Is still water better for you than sparkling water?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Still or sparkling? It’s a question you’ll commonly hear in a café or restaurant and you probably have a preference. But is there any difference for your health? If you love the fizz, here’s why you don’t have to pass on the sparkling water. <h2>What makes my water sparkle?</h2> This article specifically focuses on comparing still filtered water to carbonated filtered water (called “sparkling water” or “unflavoured seltzer”). Soda water, mineral water, tonic water and flavoured water are similar, but not the same product. The bubbles in sparkling water are created by adding carbon dioxide to filtered water. It reacts to produce carbonic acid, which makes sparkling water more acidic (a pH of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5747581/">about 3.5</a>) than still (closer to neutral, with a pH around 6.5-8.5). <h2>Which drink is healthiest?</h2> Water is the best way to hydrate our bodies. Research shows when it comes to <a href="https://pubmed.ncbi.nlm.nih.gov/26702122/">hydration</a>, still and sparkling water are <a href="https://www.jstage.jst.go.jp/article/jnsv/58/5/58_333/_article">equally effective</a>. Some people believe water is healthier when it comes from a sealed bottle. But in Australia, tap water is <a href="https://www.waterquality.gov.au/guidelines/drinking-water">monitored very carefully</a>. Unlike bottled water, it also has the added benefit of fluoride, which can help protect young children against <a href="https://linkinghub.elsevier.com/retrieve/pii/S0002-8177(14)60225-7">tooth decay</a> and cavities. Sparkling or still water is always <a href="https://pubmed.ncbi.nlm.nih.gov/30354445/">better</a> than artificially sweetened flavoured drinks or juices. <h2>Isn’t soda water bad for my teeth and bones?</h2> There’s no evidence sparkling water damages your bones. While drinking a lot of soft drinks is linked to increased <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071508/">fractures</a>, this is largely due to their association with higher rates of obesity. Sparkling water is more acidic than still water, and acidity can soften the teeth’s <a href="https://pubmed.ncbi.nlm.nih.gov/35635779/">enamel</a>. Usually this is not something to be too worried about, unless it is mixed with sugar or citrus, which has much higher levels of acidity and can harm teeth. However, if you grind your teeth often, the softening could enhance the <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/teeth-grinding#risk-factors-for-tooth-grinding">damage it causes</a>. If you’re undertaking a home whitening process, sparkling water <a href="https://pubmed.ncbi.nlm.nih.gov/39123328/">might discolour</a> your teeth. In most other cases, it would take a lot of sparkling water to pass by the teeth, for a long period of time, to cause any noticeable damage. <h2>How does drinking water affect digestion?</h2> There is a <a href="https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/expert-answers/digestion/faq-20058348">misconception</a> drinking water (of any kind) with a meal is bad for digestion. While theoretically water could dilute stomach acid (which breaks down food), the practice of drinking it doesn’t appear <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11045127/">to have any negative effect</a>. Your digestive system simply adapts to the consistency of the meal. Some people do find that carbonated beverages cause some stomach upset. This is due to the build-up of <a href="https://www.sciencedirect.com/science/article/pii/S0939475309000787">gases</a>, which can cause bloating, cramping and discomfort. For people with an <a href="https://www.nature.com/articles/s41598-023-44916-8">overactive bladder</a>, the acidity might also aggravate the <a href="https://journals.physiology.org/doi/full/10.1152/ajpcell.00441.2022">urinary</a> system. Interestingly, the fizzy “<a href="https://pubmed.ncbi.nlm.nih.gov/34399552/">buzz</a>” you feel in your mouth from sparkling water fades the more you drink it. <h2>Is cold water harder to digest?</h2> You’ve chosen still or sparkling water. What about its temperature? There are surprisingly few studies about the effect of drinking cold water compared to room temperature. There is some evidence colder water (at two degrees Celsius) might inhibit <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7000532/">gastric contractions</a> and slow down digestion. Ice water may constrict blood vessels and cause <a href="https://www.sciencedirect.com/science/article/abs/pii/0306362383900642">cramping</a>. However other research suggests drinking cold water might temporarily boost <a href="https://academic.oup.com/jcem/article/88/12/6015/2661518">metabolism</a>, as the body needs to expend energy to warm it up to body temperature. This effect is minimal and unlikely to lead to significant <a href="https://academic.oup.com/jcem/article/91/9/3598/2656772">weight loss</a>. <h2>Which water wins?</h2> The bottom line is water is essential, hydrates us and has countless other <a href="https://news.com.au/lifestyle/health/diet/fewer-than-25-per-cent-simple-question-most-aussies-cant-answer/news-story/04693f23f03d9e8b6483cf34b47d9fcb">health benefits</a>. Water, with carbonated bubbles or without, will always be the healthiest drink to choose. And if you’re concerned about any impact to teeth enamel, one trick is to follow sparkling water with a glass of still. This helps rinse the teeth and return your mouth’s acidity back to normal.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237125/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, Associate Professor of Science & Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, Senior Teaching Fellow, Medical Program, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Australia’s gender pay gap has hit a record low – but we still have work to do

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/leonora-risse-405312">Leonora Risse</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Australia’s gender pay gap – a key measure of economic inequality between men and women – has fallen to a record low of 11.5%. That’s down from 13% this time last year, the steepest annual fall since 2016. Ten years ago, it was almost 19%. The latest figures are great news for our economy and our society – evidence we’re getting better at recognising and fairly valuing women’s capabilities and contributions. More opportunities are now open to women in the workforce, helping them gain and retire with greater financial independence than in previous decades. But national averages don’t tell the whole story. While gender pay gaps have fallen in some industries, they’ve also been rising in others. Today, August 19, is <a href="https://www.wgea.gov.au/pay-and-gender/equal-pay-day-2024">equal pay day</a>. This marks the 50 extra days past the end of the last financial year that Australian women would need to work for their earnings to match those of their male colleagues. This offers us a timely opportunity to reflect on what exactly has driven this year’s improvement – and where we still have work to do. <h2>Women’s earnings picking up pace</h2> We calculate the gender pay gap by comparing the average weekly ordinary-time, full-time <a href="https://www.abs.gov.au/statistics/labour/earnings-and-working-conditions/average-weekly-earnings-australia">earnings</a> for men and women. In dollar terms, women are now earning $231.50, or 11.5%, less than men, on average, in their weekly full-time pay packet. <hr /> <iframe id="HwwJ5" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/HwwJ5/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> The recent narrowing is being driven by women’s average earnings growth picking up pace. This contrasts with <a href="https://www.abc.net.au/news/2018-10-02/fact-check-gender-pay-gap/10302358">earlier periods</a> in which the narrowing of the gap tended to be due to a slowdown in the growth of men’s earnings. <hr /> <iframe id="R7uFE" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/R7uFE/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>What’s behind the improvement?</h2> While changes in the gender pay gap reflect a range of economy-wide factors, the Albanese government has been quick to attribute the recent fall to the various <a href="https://www.linkedin.com/feed/update/urn:li:activity:7229747376511447040/">targeted actions</a> it has taken since coming to office. Let’s look at whether and how these actions have played a role. First, the government sought to make wage information more transparent. It <a href="https://theconversation.com/pay-secrecy-clauses-are-now-banned-in-australia-heres-how-that-could-benefit-you-195814">banned pay secrecy clauses</a> and now requires the gender pay gaps of all large companies in Australia to be <a href="https://theconversation.com/qantas-pays-women-37-less-telstra-and-bhp-20-fifty-years-after-equal-pay-laws-we-still-have-a-long-way-to-go-223870">publicly reported</a>. These reforms took effect from 2023, targeting private companies. The gender pay gap in the private sector, though higher to begin with, has fallen more swiftly than that of the public sector, suggesting these actions have had an effect. <hr /> <iframe id="ZKMdm" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/ZKMdm/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> Second, the government targeted gender-patterned biases in industrial relations – including the <a href="https://theconversation.com/50-years-after-equal-pay-the-legacy-of-womens-work-remains-118761">legacy effects</a> of past decisions – and instilled gender equity as a new objective of Australia’s Fair Work Act. The Fair Work Commission is now required to take gender equity into account in its wage deliberations, including its <a href="https://www.fwc.gov.au/documents/resources/2024fwcfb3500.pdf">minimum wage decision</a>. The government also introduced multi-employer bargaining in an attempt to strengthen workers’ bargaining capacity in female-concentrated sectors. The effects of these changes will continue to flow across the workforce as the Fair Work Commission undertakes its review of modern awards, prioritising those affecting <a href="https://www.fwc.gov.au/hearings-decisions/major-cases/gender-undervaluation-priority-awards-review">female-concentrated industries</a>. <figure class="align-right zoomable"><figcaption></figcaption></figure> And third, further addressing the historical undervaluation of “women’s work”, the government directly addressed low pay in female-concentrated sectors by supporting a pay rise for <a href="https://www.fairwork.gov.au/newsroom/news/15-per-cent-wage-increase-aged-care-sector">aged care workers</a>. Targeting the low pay and under-valuation of an industry that is about 87% female helped fuel the downward momentum in the overall gender pay gap. The government’s recently announced pay rise for <a href="https://ministers.education.gov.au/anthony-albanese/pay-rise-early-educators-while-keeping-fees-down-families">early childhood education and care workers</a> – a workforce that is around 95% female – will also target gender patterns in low pay once they come into effect. These government actions have been essential for undoing the gender biases embedded in existing systems. And they have complemented other initiatives that have taken effect in the past year, such as the <a href="https://www.respectatwork.gov.au/new-positive-duty-employers-prevent-workplace-sexual-harassment-sex-discrimination-and-victimisation">Respect At Work Act</a>, requiring employers to proactively stamp out sexual harassment. But there is still a way to go to keep closing the gender gaps across all parts of the workforce. <h2>Falling in some industries, rising in others</h2> Breaking down the gender pay gap in earnings by sector paints a more varied picture. In industries like construction, public administration and safety, and retail trade, it has fallen notably over the past two years. <hr /> <iframe id="poLND" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/poLND/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> But it remains high in industries like healthcare and social assistance, at over 20%, and finance and insurance at 18%. <hr /> <iframe id="6cLnT" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/6cLnT/2/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> In some industries, the gap has actually increased over the past two years. In arts and recreation services, as well as electricity, gas, waste and water services, it’s been continually rising. <hr /> <iframe id="M8fve" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/M8fve/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>That could reflect a bigger shift</h2> It’s important to interpret these figures carefully. In some instances, a widening of the gender pay gap can reflect a positive shift in an industry’s makeup, if it reflects more women joining a male-dominated sector at entry level, and growing a pipeline of senior women for the future. That’s why the Workplace Gender Equality Agency (WGEA) gives organisations a chance to explain these dynamics in their <a href="https://www.wgea.gov.au/about/our-legislation/publishing-employer-gender-pay-gaps">employer statements</a>, which are published on the WGEA website alongside organisations’ gender pay gaps. Over time, the entry of more women at the junior level can flow through to more gender balance as these women progress to senior and decision-making roles. The real test will be to ensure – by fostering more gender equitable, inclusive and respectful work cultures and systems – that they do.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236894/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/leonora-risse-405312">Leonora Risse</a>, Associate Professor in Economics, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I’ve recovered from a cold but I still have a hoarse voice. What should I do?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/yeptain-leung-1563747">Yeptain Leung</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Cold, flu, COVID and <a href="https://theconversation.com/rsv-is-everywhere-right-now-what-parents-need-to-know-about-respiratory-syncytial-virus-208855">RSV</a> have been <a href="https://www.abc.net.au/news/2024-06-21/flu-whooping-cough-rsv-cases-up-as-covid-cases-unkown/104002964">circulating across Australia this winter</a>. Many of us have caught and recovered from <a href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">one of these</a> common upper respiratory tract infections. But for some people their impact is ongoing. Even if your throat isn’t <a href="https://theconversation.com/sore-throats-suck-do-throat-lozenges-help-at-all-184454">sore</a> anymore, your voice may still be hoarse or croaky. So what happens to the voice when we get a virus? And what happens after? Here’s what you should know if your voice is still hoarse for days – or even weeks – after your other symptoms have resolved. <h2>Why does my voice get croaky during a cold?</h2> A healthy voice is normally clear and strong. It’s powered by the lungs, which push air past the vocal cords to make them vibrate. These vibrations are amplified in the throat and mouth, creating the voice we hear. The vocal cords are two elastic muscles situated in your throat, around the level of your laryngeal prominence, or Adam’s apple. (Although everyone has one, it tends to be more pronounced in males.) The vocal cords are small and delicate – around the size of your fingernail. Any small change in their structure will affect how the voice sounds. When the vocal cords become inflamed – known as laryngitis – your voice will sound different. Laryngitis is a common part of upper respiratory tract infections, but can also be caused through misuse. <figure class="align-center "><img src="https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=366&fit=crop&dpr=1 600w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=366&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=366&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=460&fit=crop&dpr=1 754w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=460&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=460&fit=crop&dpr=3 2262w" alt="Two drawn circles comparing normal vocal cords with inflamed, red vocal cords." /><figcaption>Viruses such as the common cold can inflame the vocal cords. <a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458117">Pepermpron/Shutterstock</a></figcaption></figure> Catching a virus triggers the body’s defence mechanisms. White blood cells are recruited to kill the virus and heal the tissues in the vocal cords. They become inflamed, but also stiffer. It’s harder for them to vibrate, so the voice comes out hoarse and croaky. In some instances, you may find it hard to speak in a loud voice or have a reduced pitch range, meaning you can’t go as high or loud as normal. You may even “lose” your voice altogether. Coughing can also make things worse. It is the body’s way of trying to clear the airways of irritation, including your own mucus dripping onto your throat (<a href="https://www.health.harvard.edu/staying-healthy/treatments-for-post-nasal-drip">post-nasal drip</a>). But coughing slams the vocal cords together with force. Chronic coughing can lead to persistent inflammation and even thicken the vocal cords. This thickening is the body trying to protect itself, similar to developing a callus when a pair of new shoes rubs. Thickening on your vocal cords can lead to physical changes in the vocal cords – such as developing a growth or “nodule” – and further deterioration of your voice quality. <figure class="align-center "><img src="https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=376&fit=crop&dpr=1 600w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=376&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=376&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=473&fit=crop&dpr=1 754w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=473&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=473&fit=crop&dpr=3 2262w" alt="Diagram compares healthy vocal cords with cords that have nodules, two small bumps." /><figcaption>Coughing and exertion can cause inflamed vocal cords to thicken and develop nodules. <a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458126">Pepermpron/Shutterstock</a></figcaption></figure> <h2>How can you care for your voice during infection?</h2> People who use their voices a lot professionally – such as teachers, call centre workers and singers – are often desperate to resume their vocal activities. They are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7478078/">more at risk</a> of forcing their voice before it’s ready. The good news is most viral infections resolve themselves. Your voice is usually restored within five to ten days of recovering from a cold. Occasionally, your pharmacist or doctor may prescribe cough suppressants to limit additional damage to the vocal cords (among other reasons) or mucolytics, which break down mucus. But the most effective treatments for viral upper respiratory tract infections are hydration and rest. Drink plenty of water, avoid alcohol and exposure to cigarette smoke. <a href="https://www.healthdirect.gov.au/laryngitis#:%7E:text=You%20can%20help%20your%20voice%20recover%20by%3A%201,avoid%20nasal%20decongestants%20%28these%20make%20your%20throat%20drier%29">Inhaling steam</a> by making yourself a cup of hot water will also help clear blocked noses and hydrate your vocal cords. Rest your voice by talking as little as possible. If you do need to talk, don’t whisper – this <a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199704001730">strains the muscles</a>. Instead, consider using “<a href="https://www.instagram.com/reel/C0d-oNIMM1y/">confidential voice</a>”. This is a soft voice – not a whisper – that gently vibrates your vocal cords but puts less strain on your voice than normal speech. Think of the voice you use when communicating with someone close by. During the first five to ten days of your infection, it is important not to push through. Exerting the voice by talking a lot or loudly will only exacerbate the situation. Once you’ve recovered from your cold, you can speak as you would normally. <h2>What should you do if your voice is still hoarse after recovery?</h2> If your voice hasn’t returned to normal after <a href="https://www.healthdirect.gov.au/laryngitis">two to three weeks</a>, you should seek medical attention from your doctor, who may refer you to an ear nose and throat specialist. If you’ve developed a nodule, the specialist would likely refer you to a speech pathologist who will show you how to take care of your voice. Many nodules can be <a href="https://britishvoiceassociation.org.uk/voicecare_vocal-nodules.htm">treated</a> with voice therapy and don’t require surgery. You may have also developed a habit of straining your vocal cords, if you forced yourself to speak or sing while they were inflamed. This can be a reason why some people continue to have a hoarse voice even when they’ve recovered from the cold. In those cases, a speech pathologist may play a valuable role. They may teach you to exercises that make voicing more efficient. For example, <a href="https://www.youtube.com/watch?v=fwNPp-RS4IY">lip trills</a> (blowing raspberries) are a fun and easy way you can learn to relax the voice.

4 ways to cut down on meat when dining out – and still make healthy choices

<div class="theconversation-article-body"> .<a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Many of us are looking for ways to eat a healthier and more <a href="https://theconversation.com/how-sustainable-is-your-weekly-grocery-shop-these-small-changes-can-have-big-benefits-234367">sustainable diet</a>. And one way to do this is by reducing the amount of meat we eat. That doesn’t mean you need to become a <a href="https://theconversation.com/why-you-should-eat-a-plant-based-diet-but-that-doesnt-mean-being-a-vegetarian-78470">vegan or vegetarian</a>. Our <a href="https://jn.nutrition.org/article/S0022-3166(24)00333-X/fulltext">recent research</a> shows even small changes to cut down on meat consumption could help improve health and wellbeing. But not all plant-based options are created equal and some are <a href="https://pubmed.ncbi.nlm.nih.gov/30744710/">ultra-processed</a>. Navigating what’s available when eating out – including options like tofu and fake meats – can be a challenge. So what are your best options at a cafe or restaurant? Here are some guiding principles to keep in mind when cutting down on meat. <h2>Health benefits to cutting down</h2> Small amounts of lean meat can be part of a healthy, balanced diet. But the majority of Australians <a href="https://cancer.org.au/about-us/policy-and-advocacy/prevention/obesity/related-resources/meat-and-cancer#consumption">still eat more meat</a> than recommended. Only a small percentage of Australians (10%) are vegetarian or vegan. But an <a href="https://www.foodfrontier.org/wp-content/uploads/2019/10/Food-Frontier-Hungry-For-Plant-Based-Australian-Consumer-Insights.pdf">increasing</a> number opt for a <a href="https://theconversation.com/love-meat-too-much-to-be-vegetarian-go-flexitarian-73741">flexitarian</a> diet. <a href="https://theconversation.com/whats-the-difference-between-vegan-and-vegetarian-225275">Flexitarians</a> eat a diet rich in fruits and vegetables, while still enjoying small amounts of meat, dairy, eggs and fish. Our <a href="https://jn.nutrition.org/article/S0022-3166(24)00333-X/fulltext">recent research</a> looked at whether the average Australian diet would improve if we swapped meat and dairy for plant-based alternatives, and the results were promising. The study found health benefits when people halved the amount of meat and dairy they ate and replaced them with healthy plant-based foods, like tofu or <a href="https://www.heartfoundation.org.au/blog/why-you-need-legumes-in-your-life">legumes</a>. On average, their dietary fibre intake – which helps with feeling fuller for longer and digestive health – went up. Saturated fats – which increase our blood cholesterol levels, a risk factor for heart disease – went down. Including more fibre and less saturated fat helps reduce the risk of <a href="https://www.heartfoundation.org.au/healthy-living/healthy-eating/healthy-eating-to-protect-your-heart">heart disease</a>. Achieving these health benefits may be as simple as swapping ham for baked beans in a toastie for lunch, or substituting half of the mince in your bolognese for lentils at dinner. <h2>How it’s made matters</h2> For a long time we’ve known processed meats – such as ham, bacon and sausages – are bad for your health. Eating high amounts of these foods is associated with poor <a href="https://www.heartfoundation.org.au/healthy-living/healthy-eating/protein-and-heart-health">heart health</a> and some forms of <a href="https://cancer.org.au/cancer-information/causes-and-prevention/diet-and-exercise/meat-and-cancer-risk">cancer</a>. But the same can be true of many processed meat alternatives. Plant-based alternatives designed to mimic meat, such as sausages and burgers, have become readily available in supermarkets, cafes and restaurants. These products are ultra-processed and can be <a href="https://theconversation.com/we-looked-at-700-plant-based-foods-to-see-how-healthy-they-really-are-heres-what-we-found-222991">high in salt and saturated fat</a>. Our study found when people replaced meat and dairy with ultra-processed meat alternatives – such as plant-based burgers or sausages – they ate more salt and less calcium, compared to eating meat or healthy plant-based options. So if you’re cutting down on meat for health reasons, it’s important to think about what you’re replacing it with. The <a href="https://www.eatforhealth.gov.au/sites/default/files/2022-09/n55g_adult_brochure.pdf">Australian Dietary Guidelines</a> recommend eggs, legumes/beans, tofu, nuts and seeds. Tofu can be a great option. But we recommend flavouring plain tofu with herbs and spices yourself, as pre-marinated products are often ultra-processed and can be high in salt. <h2>What about when dining out?</h2> When you’re making your own food, it’s easier to adapt recipes or reduce the amount of meat. But when faced with a menu, it can be difficult to work out what is the best option. Here are our four ways to make healthy choices when you eat out: 1. Fill half your plate with vegetables When cutting down on meat, aim for half your plate to be vegetables. Try to also eat <a href="https://theconversation.com/were-told-to-eat-a-rainbow-of-fruit-and-vegetables-heres-what-each-colour-does-in-our-body-191337">a variety of colours</a>, such as leafy green spinach, red capsicum and pumpkin. When you’re out, this might look like choosing a vegetable-based entree, a stir-fry or ordering a side salad to have with your meal. 2. Avoid the deep fryer The Australian Dietary Guidelines <a href="https://www.eatforhealth.gov.au/sites/default/files/files/the_guidelines/n55a_australian_dietary_guidelines_summary_130530.pdf">recommend limiting</a> deep fried foods to once a week or less. When dining out, choose plant-based options that are sautéed, grilled, baked, steamed, boiled or poached – instead of those that are crumbed or battered before deep frying. This could mean choosing vegetarian dumplings that are steamed not fried, or poached eggs at brunch instead of fried. Ordering a side of roast vegetables instead of hot chips is also a great option. 3. Pick wholegrains Scan the menu for wholegrain options such as brown rice, wholemeal pizza or pasta, barley, quinoa or wholemeal burger buns. Not only are they good sources of protein, but they also provide more <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/grain-cereal-foods-mostly-wholegrain-and-or-high-cereal-fibre">dietary fibre</a> than refined grains, which help keep you fuller for longer. 4. If you do pick meat – choose less processed kinds You may not always want, or be able, to make a vegetarian choice when eating out and with other people. If you do opt for meat, it’s better to steer clear of processed options like bacon or sausages. If sharing dishes with other people, you could try adding unprocessed plant-based options into the mix. For example, a curry with lentils or chickpeas, or a vegetable-based pizza instead of one with ham or salami. If that’s not an option, try choose meat that’s a lean cut, such as chicken breast, or options which are grilled rather than fried.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236505/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, PhD candidate at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, NHMRC Emerging Leadership Fellow and Senior Research Fellow at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The tragic reason Miriam Margolyes is still working at 83

Miriam Margolyes has shared the tragic reason that she is still working in showbiz at the age of 83. The acting legend has long suffered with spinal stenosis – a condition that occurs when the spinal canal or neural foramen narrows, putting pressure on the spinal cord and nerve roots. Despite suffering from the debilitating illness, the 83-year-old British star has appeared on numerous TV shows over the years. Now, speaking candidly to the Radio Times, Margolyes admitted that she is still working to fund her medical bills. She said, “I’m worried that I won’t have enough money for carers when I finally get paralysed or whatever it is that’s going to happen to me.” Despite dealing with the physical constraints that come from both her spinal stenosis and her age, which she finds “limiting and depressing”, she said she refuses to slow her pace. “When you know that you haven’t got long to live and I’m probably going to die within the next five or six years, if not before, I’m loath to leave behind performing. It’s such a joy.” “I yearn to play roles that don’t confine me to wheelchairs, but I’m just not strong enough.” Margolyes recently underwent major heart surgery, speaking candidly about the operation with the Table Manners podcast. “I’ve got a cow’s heart now,” she said. “Well, not the whole heart. I’ve had an aortic valve replaced by a cow’s aortic valve. “I don’t know how common it is. I’d never heard of that operation. But it saves you from having open-heart surgery, which would be infinitely more invasive.” In the same interview, Margolyes revealed she expected to be a wheelchair soon. “When you get old you become obviously aware of your vulnerability. I have a bad back, I’m probably going to be in a wheelchair soon and you have to come to terms with what life throws at you.” Image credits: Ken McKay/ITV/Shutterstock Editorial

Think you’ve decided what to buy? Actually, your brain is still deciding – even as you put it in your basket

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/tijl-grootswagers-954175">Tijl Grootswagers</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>; <a href="https://theconversation.com/profiles/genevieve-l-quek-1447582">Genevieve L Quek</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>, and <a href="https://theconversation.com/profiles/manuel-varlet-156210">Manuel Varlet</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> You are standing in the cereal aisle, weighing up whether to buy a healthy bran or a sugary chocolate-flavoured alternative. Your hand hovers momentarily before you make the final grab. But did you know that during those last few seconds, while you’re reaching out, your brain is still evaluating the pros and cons – influenced by everything from your last meal, the health star rating, the catchy jingle in the ad, and the colours of the letters on the box? Our recently published <a href="https://www.nature.com/articles/s41598-024-62135-7">research</a> shows our brains do not just think first and then act. Even while you are reaching for a product on a supermarket shelf, your brain is still evaluating whether you are making the right choice. Further, we found measuring hand movements offers an accurate window into the brain’s ongoing evaluation of the decision – you don’t have to hook people up to expensive brain scanners. What does this say about our decision-making? And what does it mean for consumers and the people marketing to them? <h2>What hand movements tell us about decision-making</h2> There has been <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-psych-010419-051053">debate within neuroscience</a> on whether a person’s movements to enact a decision can be modified once the brain’s “motor plan” has been made. Our research revealed not only that movements can be changed after a decision – “in flight” – but also the changes matched incoming information from a person’s senses. To study <a href="https://doi.org/10.1038/s41598-024-62135-7">how our decisions unfold over time</a>, we tracked people’s hand movements as they reached for different options shown in pictures – for example, in response to the question “is this picture a face or an object?” When choices were easy, their hands moved straight to the right option. But when choices were harder, new information made the brain change its mind, and this was reflected in the trajectory of their hand movements. When we compared these hand movement trajectories to brain activity recorded using neuroimaging, we found that the timing and amount of evidence of the brain’s evaluation matched the movement pattern. Put simply, reaching movements are shaped by ongoing thinking and decision-making. By showing that brain patterns match movement trajectories, our research also highlights that large, expensive brain scanners may not always be required to study the brain’s decision evaluation processes, as movement tracking is much more cost-effective and much easier to test on a large scale. <h2>What does this mean for consumers and marketers?</h2> For consumers, knowing our brains are always reevaluating decisions we might think of as “final” can help us be more aware of our choices. For simple decisions such as choosing a breakfast cereal, the impact may be small. Even if you have preemptively decided on a healthy option, you might be tempted at the last minute by the flashy packaging of a less healthy choice. But for important long-term decisions such as choosing a mortgage, it can have serious effects. On the other side of the coin, marketers have long known that many purchase decisions are <a href="https://www.sciencedirect.com/science/article/pii/S0969698912000781">made on the spot</a>. They use strategies such as attractive packaging and strategic product placement to influence people’s decisions. New ways of studying how people’s brains process information – right up to the last minute – can help marketers design more effective strategies. <h2>Opportunities for further research</h2> Further research in this area could explore how different types of information, such as environmental cues or memories, affect this continuous decision evaluation process in different groups of people. For example, how do people of different ages process information while making decisions? Our finding – that hand movements reflect the inner workings of the brain’s decision making process – could make future studies cheaper and more efficient. The ability to fine-tune marketing in this way has implications beyond just selling products. It can also make public strategic messaging far more effective. This could include tailoring a public health campaign on vaping specifically for people aged under 30, or targeting messaging about superannuation scams more effectively at those of retirement age. The act of reaching for a product is not a simple consequence of a decision already made; it’s a highly dynamic process. Being aware of what influences our last-minute decision-making can help us make better choices that have better outcomes.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/234167/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/tijl-grootswagers-954175">Tijl Grootswagers</a>, Senior Research Fellow in Cognitive Neuroscience, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>; <a href="https://theconversation.com/profiles/genevieve-l-quek-1447582">Genevieve L Quek</a>, Research Fellow, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>, and <a href="https://theconversation.com/profiles/manuel-varlet-156210">Manuel Varlet</a>, Associate Professor in Cognitive Neuroscience, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Still fab after 60 years: how The Beatles’ A Hard Day’s Night made pop cinema history

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/alison-blair-223267">Alison Blair</a>, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a> I first saw A Hard Day’s Night at a film festival over 20 years ago, at the insistence of my mum. By then, it was already decades old, but I remember being enthralled by its high-spirited energy. A Beatles fan, mum had introduced me to the band’s records in my childhood. At home, we listened to Please Please Me, the band’s 1963 single, and the Rubber Soul album from 1965, which I loved. Television regularly showed old black-and-white scenes of Beatlemania that, to a ten-year-old in the neon-lit 1980s, seemed like ancient history. But then, I’d never seen a full-length Beatles film. I had no idea what I was in for. When the lights went down at Dunedin’s Regent Theatre, the opening chord of the film’s title song announced its intentions: an explosion of youthful vitality, rhythmic visuals, comical high jinks and the electrifying thrill of Beatlemania in 1964. This time, it didn’t seem ancient at all. Since that first viewing, I’ve returned to A Hard Day’s Night again and again. I now show it to my students as a historically significant example of pop music film making – visually inventive cinema, emblematic of a fresh era in youth culture, popular music and fandom. <h2>Beatlemania on celluloid</h2> A musical comedy depicting a chaotic 36 hours in the life of the Beatles, A Hard Day’s Night has now reached its 60th anniversary. Directed by <a href="https://www.imdb.com/name/nm0504513/">Richard Lester</a>, the film premiered in London on July 6 1964, with its first public screening a day later (incidentally, also Ringo Starr’s birthday), and the <a href="https://www.discogs.com/master/24003-The-Beatles-A-Hard-Days-Night">album of the same name</a> released on July 10. The band’s popularity was by then reaching dizzying heights of hysteria, all reflected in the film. The Beatles are chased by hordes of fans, take a train trip, appear on TV, run from the police in a Keystone Cops-style sequence, and play a televised concert in front of screaming real-life Beatles fans. Side one of the album provides the soundtrack, and the film inspired pop music film and video from then on, from the <a href="https://www.imdb.com/title/tt0060010/">Monkees TV series</a> (1966–68) to the Spice Girls’ <a href="https://www.imdb.com/title/tt0120185/">Spice World</a> (1997) and music videos as we know them today. <h2>The original music video</h2> Postwar teen culture and consumerism had been on the rise since the 1950s. In 1960s Britain, youth music TV programmes, notably <a href="https://www.imdb.com/title/tt0196287/">Ready Steady Go!</a> (1963–66), meant pop music now had a developing visual culture. The youthful zest and vitality of ‘60s London was reflected in the pop-cultural sensibility, modern satirical humour and crisp visual impact of A Hard Day’s Night. Influenced by <a href="https://nofilmschool.com/french-new-wave-cinema">French New Wave</a> film making, and particularly the early 1960s work of <a href="https://www.imdb.com/name/nm0000419/">Jean-Luc Godard</a>, A Hard Day’s Night employs <a href="https://indiefilmhustle.com/cinema-verite/">cinéma vérité</a>-style hand-held cinematography, brisk jump cuts, unusual framing and dynamic angles, high-spirited action, and a self-referential nonchalance. The film also breaks the “fourth wall”, with characters directly addressing the audience in closeup, and reveals the apparatus of the visual performance of music: cameras and TV monitors are all part of the frame. Cutting the shots to the beat of the music – as in the Can’t Buy Me Love sequence – lends a visual rhythm that would later become the norm in music video editing. Lester developed this technique further in the second Beatles film, <a href="https://www.imdb.com/title/tt0059260/">Help!</a> (1965). The closing sequence of A Hard Day’s Night is possibly the film’s most dynamic: photographic images of the band edited to the beat in the style of stop-motion animation. Sixty years on, it still feels fresh, especially as so much contemporary film making remains hidebound by formulaic Hollywood rules. <figure class="align-center "><img src="https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=453&fit=crop&dpr=1 600w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=453&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=453&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=569&fit=crop&dpr=1 754w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=569&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/604790/original/file-20240704-17-ov77mn.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=569&fit=crop&dpr=3 2262w" alt="A Hard Day's Night movie poster" /><figcaption>A new pop aesthetic: original film poster for A Hard Day’s Night. Getty Images</figcaption></figure> <h2>Slapstick and class awareness</h2> As with much popular culture from the past, the humour in A Hard Day’s Night doesn’t always doesn’t land the way it would have in 1964. And yet, there are moments that seem surprisingly modern in their razor-sharp irony. In particular, the band’s Liverpudlian working-class-lad jibes and chaotic energy contrast brilliantly with the film’s upper-class characters. Actor Victor Spinetti’s comically over-anxious TV director, constantly hand-wringing over the boys’ rebelliousness, underscores the era-defining change the Beatles represented. Corporate pop-culture consumerism is also satirised. John Lennon “snorts” from a Coca-Cola bottle, a moment so knowingly silly it registers as more contemporary than it really is. George Harrison deflects a journalist’s banal questions with scathingly witty answers, and cuts a fashion company down to size by describing their shirt designs as “grotesque”. And there is Paul McCartney’s running joke that his grandfather – played by Wilfred Brambell from groundbreaking sitcom <a href="https://www.imdb.com/title/tt0057785/">Steptoe and Son</a> (1962–74) – is “very clean”. Even the film’s old-fashioned visual slapstick still holds up in 2024. Showing the film to this year’s students, I didn’t expect quite as much laughter when Ringo’s attempts to be chivalrous result in a fall-down-a-hole mishap. In 2022, the <a href="https://www.criterion.com/">Criterion Collection</a> released a high-resolution restoration of the film, so today A Hard Day’s Night can be seen in all its fresh, black-and-white, youthful vigour. Happy 60th, A Hard Day’s Night. And happy 84th, Ringo. Both still as lively and energetic as ever.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/228598/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/alison-blair-223267">Alison Blair</a>, Teaching Fellow in Music, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a> Image credits: THA/Shutterstock Editorial This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why it’s still a scientific mystery how some can live past 100 – and how to crack it

A few tightly linked biological processes, sometimes called the <a href="https://pubmed.ncbi.nlm.nih.gov/23746838/">“hallmarks of ageing”</a>, including our supply of stem cells and communication between cells, act to keep us healthy in the early part of our lives – with <a href="https://theconversation.com/the-secret-to-staying-young-scientists-boost-lifespan-of-mice-by-deleting-defective-cells-54068">problems arising as these start to fail</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/34699859/">Clinical trials are ongoing</a> to see if targeting some of these hallmarks can improve <a href="https://pubmed.ncbi.nlm.nih.gov/31542391/">diabetic kidney disease</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/29997249/">aspects of</a> <a href="https://pubmed.ncbi.nlm.nih.gov/33977284/">immune function</a> and age-related <a href="https://pubmed.ncbi.nlm.nih.gov/30616998/">scarring of the lungs</a> among others. So far, so good. Unfortunately, big, unanswered questions remain in the biology of ageing. To evaluate what these are and how to address them, the <a href="https://www.afar.org/">American Federation For Aging Research</a>, a charity, recently convened a series of <a href="https://www.afar.org/imported/AFAR_GeroFuturesThinkTankReport_November2021.pdf">meetings for leading scientists and doctors</a>. The experts agreed that understanding what is special about the biology of humans who survive more than a century is now a key challenge. These centenarians <a href="https://www.statista.com/chart/18826/number-of-hundred-year-olds-centenarians-worldwide/">comprise less than 0.02% of the UK population</a> but have exceeded the life expectancy of their peers by almost 50 years (babies born in the 1920s typically had a life expectancy of less than 55). How are they doing it? We know that centenarians live so long because they are unusually healthy. They remain in good health for about 30 years longer than most normal people and when they finally fall ill, they are only sick for a very short time. This <a href="https://pubmed.ncbi.nlm.nih.gov/27377170/">“compression of morbidity”</a> is clearly good for them, but also benefits society as a whole. In the US, the medical care costs for a centenarian in their last two years of life <a href="https://www.cdc.gov/nchs/data/series/sr_10/sr10_198.pdf">are about a third of those of someone who dies in their seventies</a> (a time when most centenarians don’t even need to see a doctor). The children of centenarians are also much healthier than average, indicating they are inheriting something beneficial from their parents. But is this genetic or environmental? <h2>Centenarians aren’t always health conscious</h2> Are centenarians the poster children for a healthy lifestyle? For the general population, watching your weight, not smoking, drinking moderately and eating at least five servings of fruit and vegetables a day can <a href="https://pubmed.ncbi.nlm.nih.gov/27296932/">increase life expectancy by up to 14 years</a> compared with someone who does none of these things. This difference <a href="https://publications.parliament.uk/pa/ld5801/ldselect/ldsctech/183/18305.htm#_idTextAnchor012">exceeds that seen</a> between the least and most deprived areas in the UK, so intuitively it would be expected to play a role in surviving for a century. But astonishingly, this needn’t be the case. <a href="https://pubmed.ncbi.nlm.nih.gov/21812767/">One study</a> found that up to 60% of Ashkenazi Jewish centenarians have smoked heavily most of their lives, half have been obese for the same period of time, less than half do even moderate exercise and under 3% are vegetarians. The children of centenarians appear no more health conscious than the general population either. Compared to peers with the same food consumption, wealth and body weight, however, <a href="https://pubmed.ncbi.nlm.nih.gov/29050682/">they have half the prevalence of cardiovascular disease</a>. There is something innately exceptional about these people. <h2>The big secret</h2> Could it be down to rare genetics? If so, then there are two ways in which this could work. Centenarians might carry unusual genetic variants that extend lifespan, or instead they might lack common ones that cause late-life disease and impairment. Several studies, including our own work, <a href="https://pubmed.ncbi.nlm.nih.gov/32860726/">have shown</a> that centenarians have just as many bad genetic variants as the general population. Some even carry two copies of the largest known common risk gene for Alzheimer’s disease (APOE4), but still don’t get the illness. So a plausible working hypothesis is that centenarians carry rare, beneficial genetic variations rather than a lack of disadvantageous ones. And the best available data is consistent with this. Over 60% of centenarians have genetic changes that alter the genes which regulate growth in early life. This implies that these remarkable people are human examples of a type of lifespan extension observed in other species. Most people know that <a href="https://pubmed.ncbi.nlm.nih.gov/28803893/">small dogs tend to live longer than big ones</a> but fewer are aware that this is a general phenomenon across the animal kingdom. <a href="https://pubmed.ncbi.nlm.nih.gov/26857482/">Ponies can live longer than horses</a> and many strains of laboratory mice with dwarfing mutations <a href="https://pubmed.ncbi.nlm.nih.gov/29653683/">live longer than their full-sized counterparts</a>. One potential cause of this is reduced levels of a growth hormone called IGF-1 – although human centenarians <a href="https://pubmed.ncbi.nlm.nih.gov/28630896/">are not necessarily shorter than the rest of us</a>. Obviously, growth hormone is necessary early on in life, but there is increasing evidence that high levels of IGF-1 in mid to late life <a href="https://pubmed.ncbi.nlm.nih.gov/18316725/">are associated with increased late-life illness</a>. The detailed mechanisms underlying this remain an open question, but even among centenarians, women with the lowest levels of growth hormone <a href="https://pubmed.ncbi.nlm.nih.gov/24618355/">live longer than those with the highest</a>. They also have better cognitive and muscle function. That doesn’t solve the problem, though. Centenarians are also different from the rest of us in other ways. For example, they tend to have good cholesterol levels – hinting there may several reasons for their longevity. Ultimately, centenarians are “natural experiments” who show us that it is possible to live in excellent health even if you have been dealt a risky genetic hand and chose to pay no attention to health messages – but only if you carry rare, poorly understood mutations. Understanding exactly how these work should allow scientists to develop new drugs or other interventions that target biological processes in the right tissues at the right time. If these become a reality perhaps more of us than we think will see the next century in. But, until then, don’t take healthy lifestyle tips from centenarians.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/172020/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/richard-faragher-224976">Richard Faragher</a>, Professor of Biogerontology, <a href="https://theconversation.com/institutions/university-of-brighton-942">University of Brighton</a> and <a href="https://theconversation.com/profiles/nir-barzilai-1293752">Nir Barzilai</a>, Professor of Medicine and Genetics, <a href="https://theconversation.com/institutions/albert-einstein-college-of-medicine-3638">Albert Einstein College of Medicine</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Trying to save money? Our research suggests paying in cash – while you still can

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/lachlan-schomburgk-1535737">Lachlan Schomburgk</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>; <a href="https://theconversation.com/profiles/alex-belli-1538870">Alex Belli</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>, and <a href="https://theconversation.com/profiles/arvid-o-i-hoffmann-1150527">Arvid O. I. Hoffmann</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Cash is in crisis. In Australia, it’s now only used for 16% of in-person transactions, down from <a href="https://www.rba.gov.au/publications/bulletin/2023/jun/cash-use-and-attitudes-in-australia.html">about 70%</a> in 2007. The situation is so dire that on Monday, independent federal MP Andrew Gee introduced a <a href="https://www.smh.com.au/politics/federal/saving-the-lobster-prawn-and-pineapple-mps-fight-to-force-shops-to-take-cash-20240603-p5jit4.html">private member’s bill</a> that would force businesses to accept cash or else face big fines. The reality is that over the past decade, technological advancements have utterly transformed the way we pay for goods and services. Phones and smartwatches can now easily be used to pay by card, and buy-now-pay-later schemes and cryptocurrency payments offer further alternatives. The shift away from cash only <a href="https://www.worldbank.org/en/news/press-release/2022/06/29/covid-19-drives-global-surge-in-use-of-digital-payments">accelerated</a> throughout the COVID pandemic, as health experts recommended avoiding using it for hygiene reasons. Despite these big changes in how we spend money, Australians have perhaps been more focused on how much amid a stubborn cost-of-living crisis. In light of this, our research team wanted to investigate how our choice of payment method can interact with our actual spending habits. Our <a href="https://www.sciencedirect.com/science/article/pii/S0022435924000216#bib0104">latest research</a> offers a simple solution for anyone looking to save money — carry more cash! <h2>We pay less when we pay cash</h2> Drawing on both academic and industry sources, our research team combined the results from more than four decades of prior research on spending behaviour and payment methods into a large dataset. This data spanned 71 research papers, 17 countries, and more than 11,000 participants. State-of-the-art meta-analysis techniques then allowed us to collectively analyse the results from all these prior studies, and re-examine their insights. We found that cashless payments were indeed associated with higher levels of consumer spending compared to cash transactions, something that is referred to in the literature as the “cashless effect”. This cashless effect was consistent across all other payment methods in the data set. Put simply, it doesn’t matter whether you use a credit card, debit card or a buy-now-pay-later service – you are likely to spend more money using cashless methods than when you pay with cash. <h2>The pain of paying</h2> Under the traditional economic view that consumers behave rationally, there should be no differences in spending behaviour between different payment methods – money is money after all. But the existence of the cashless effect shows that the payment methods we use do indeed influence our spending behaviour. The leading theory to explain this effect attributes it to differences in the “pain of paying”, a concept <a href="https://www.researchgate.net/publication/280711796_The_Pain_of_Paying">first coined in 1996</a> that describes the emotions we feel when spending money. Importantly, our choice of payment method can influence the level of pain felt. When paying with cash, we have to physically count out notes and coins and hand them over. Humans seek to avoid losses, and paying by cash sees us physically lose a tangible object. Conversely, nothing has to be handed over to pay cashlessly. We don’t lose anything tangible with a swipe or a tap, so it feels less painful. Preliminary neurological evidence suggests that the “pain of paying” isn’t just an abstract metaphor, and we may feel actual psychological pain with each transaction we make. <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2901808">Research</a> employing functional magnetic resonance imaging (fMRI) scans to observe brain activity in consumers has shown that paying activates brain regions related to experiencing psychological discomfort. Picture this: You’re at a theme park, excited for a fun day. You use your smartwatch to pay for snacks, souvenirs and rides. It’s all so convenient that you don’t realise how much you’re spending until you check your account later and see that you have completely blown your budget! This is the cashless effect in action − if nothing is physically handed over, it’s easy to lose track of how much is spent. <h2>A great tool for budgeting – while it lasts</h2> The cost of living crisis has made spending control front-of-mind for many people. Our meta-analysis suggests that returning to “cold hard cash” whenever possible could be one valuable tool to help. The increased friction felt when using cash could help people better control their money, even just by providing a moment to pause and consider whether a transaction is necessary. This could help individuals make more mindful decisions, saving money while they can in an increasingly cashless world.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231499/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lachlan-schomburgk-1535737">Lachlan Schomburgk</a>, PhD Researcher in Marketing, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>; <a href="https://theconversation.com/profiles/alex-belli-1538870">Alex Belli</a>, Senior Lecturer in Marketing, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>, and <a href="https://theconversation.com/profiles/arvid-o-i-hoffmann-1150527">Arvid O.

Money & Banking

Becoming a landlord while still renting? ‘Rentvesting’ promises a foot on the property ladder, but watch your step

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/james-graham-1264059">James Graham</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> As home ownership moves further out of reach for many Australians, “rentvesting” is being touted as a lifesaver. Rentvesting is the practice of renting one property to live in yourself, while simultaneously purchasing an investment property somewhere cheaper and leasing it out. Ideally, “rentvestors” get to enjoy the capital gains on an investment property while living where they actually want to live, allowing them to cash in and upsize to their dream home later. It might seem like a savvy way to game the property market. But what are the risks of such an investment strategy? And how might broad adoption of this behaviour affect housing affordability in Australia? <h2>A rising tide lifts all boats differently</h2> The aim of the rentvesting game is to buy cheap property now, ride the expected capital gains, and move into a more desirable home down the track. The hope is that by climbing the first rung of the property ladder early, the whole thing won’t be pulled up out of reach. The first problem with this strategy, however, is that capital gains on housing are not always and everywhere equal. Generally, the cheapest properties available to rentvestors will be houses in the regions or apartments in the city. But both regional housing and apartment properties <a href="https://www.abc.net.au/news/2024-02-20/house-apartment-price-gap-widens-record-high-property-market/103484076">tend to appreciate more slowly</a> than the inner-city houses rentvestors might hope to live in one day. They might get a foot on the property ladder, but the rungs themselves are slowly drifting apart. Would-be rentvestors should also be aware that investments by “out-of-town” buyers tend to generate <a href="https://academic.oup.com/rfs/article-abstract/29/2/486/1902789">much lower returns</a> – both capital gains and rental yields – than investments by locals. Out-of-towners don’t know the local market trends, don’t know which neighbourhoods to avoid, and aren’t able to monitor their investments as effectively from afar. Avoiding the regions by investing in city apartments presents its own difficulties. Large, unexpected maintenance bills and poor strata management are <a href="https://www.abc.net.au/news/2024-03-21/a-world-of-hidden-charges:-strata-company-insiders/103617944">common complaints</a>. <h2>Different costs lead to different returns</h2> Perhaps the potential rentvestor should invest in something more straightforward instead, like stocks. After all, the return on equities in Australia has <a href="https://academic.oup.com/qje/article/134/3/1225/5435538">outperformed housing</a> in recent decades. However, it is much easier to borrow to invest in property than it is to borrow to invest in the stock market. And leverage is the investor’s secret weapon. For example, if house prices were to appreciate at 10% per year, then using a mortgage and a A$100,000 deposit on a $1 million property would earn you a 100% return on equity before costs. But while both investors and homeowners would earn that same basic return, their costs could be very different. For starters, property investors face capital gains tax on the proceeds of property sales, <a href="https://www.ato.gov.au/individuals-and-families/investments-and-assets/capital-gains-tax/property-and-capital-gains-tax/your-main-residence-home/eligibility-for-main-residence-exemption">unlike those selling their primary residence</a>. Banks also typically charge <a href="https://www.rba.gov.au/chart-pack/interest-rates.html">higher interest rates</a> on mortgages to investors than to homeowners. At times, the Australian Prudential Regulation Authority has also imposed caps on bank lending against investment properties, making it more difficult to find mortgage financing in the first place. Highly leveraged properties require mortgage insurance, too. Investors may need to take out larger insurance policies against the properties themselves, reflecting the higher risks associated with investment properties. Then, you also have to throw in property management fees, council rates, strata management fees and regular and unexpected maintenance costs. <h2>Negative gearing offers little benefit</h2> What about negative gearing? Property investors that generate losses on their property can deduct these costs against the tax bill on their other income. But negative gearing disproportionately benefits high-income earners with large tax bills. The <a href="https://www.abs.gov.au/statistics/labour/earnings-and-working-conditions/personal-income-australia/latest-release">median Australian individual income</a> is around $55,00, which generates a tax bill of about $8,000 – not a lot from which investment property losses can be deducted. The bigger picture is that while negative gearing helps defray the regular costs of managing a property, it doesn’t do anything to change expected capital gains. At the end of the spreadsheet tally, an investment property could end up earning rentvestors significantly less than they could have gained by simply buying their first home. <h2>Effects on housing affordability</h2> Rentvesting is new enough that its prevalence and influence awaits formal academic study. But economists might speculate about its implications for the housing market more broadly. The simplest analysis suggests that a rentvestor occupies one rental property while supplying an additional rental property to the market. If, instead, they had bought a home, they would vacate a rental property while removing another property from the market. In this case, even rentvesting en masse would have zero net effect on the housing market. But a more nuanced perspective might consider where rentvestors are renting and where they are investing. Perhaps they are most likely to rent properties in the already-crowded inner city, but purchase investment properties in regional areas where other first home buyers would like to live. This would increase demand for rentals in the city and reduce the supply of owner-occupier properties in the regions, worsening the affordability of both. Of course, if these rentvestors all eventually move up the property ladder – selling in the region and purchasing in the city – this effect would be reversed. From that longer-term perspective, rentvestors would ultimately have little effect. <h2>We still need more houses</h2> Rentvesting is not a panacea for Australia’s housing market woes. Potential investors should weigh the benefits of property investment against its substantial costs and risks. Additionally, they need to carefully consider the obvious alternative: simply buying their first home up-front. We have good reason to be wary of yet another get-rich-quick scheme involving the housing market. But initial considerations suggest that for the market overall, rentvestor behaviour is no worse than someone simply buying their first home, which we would otherwise encourage. Rather than criticising those seeking a way though our housing market morass, we might instead redouble our efforts to increase the supply of housing.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229116/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/james-graham-1264059">James Graham</a>, Lecturer in Economics, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why are adults without kids hooked on Bluey? And should we still be calling it a ‘kids’ show’?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/jessica-balanzategui-814024">Jessica Balanzategui</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/djoymi-baker-1269345">Djoymi Baker</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> “Bluey mania” shows no sign of abating. Bluey’s season finale, The Sign, was the <a href="https://tvtonight.com.au/2024/04/the-sign-breaks-abc-iview-records.html">most viewed ABC program</a> of all time on iView. A “hidden” follow-up episode, aptly named The Surprise, created a storm of <a href="https://www.dailymail.co.uk/tvshowbiz/article-13338251/Bluey-fans-wild-mystery-ending-surprise-episode-meaning.html">headlines</a> around the world, many of which <a href="https://mashable.com/article/bluey-surprise-baby-who-is-the-father">have a decidedly adult tone</a>. As highlighted in social media fan communities <a href="https://www.washingtonpost.com/arts-entertainment/2023/02/08/bluey-adult-fandom-tiktok/">and</a> <a href="https://gizmodo.com/bluey-disney-plus-bbc-australian-animation-adult-fans-1850426890">articles</a>, the show has struck a chord with adults, many of whom aren’t parents. What do they get from a show that is ostensibly “for kids”? <h2>Parents love Bluey (sometimes more than kids)</h2> Our <a href="https://www.infrastructure.gov.au/sites/default/files/documents/pfpp--australian-children%27s-television-cultures-actc.pdf">research</a> with <a href="https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiDjeXNluuFAxW2bmwGHf2aDvoQFnoECA8QAQ&url=https%3A%2F%2Fwww.aph.gov.au%2FDocumentStore.ashx%3Fid%3Dec6900b5-42b0-4c3d-b200-5c05ae895fec%26subId%3D751969&usg=AOvVaw2BpyYjP_6i62kXdJqyrplx&cshid=1714522763110954&opi=89978449">children aged 7-9</a> and their parents provides evidence of how enraptured adults are by Bluey. Our findings also suggest it’s the parents who often drive household Bluey obsessions. As one mum told us: "If we could tell the Australian TV gods something that we’d like to have on Australian TV, it would be more Bluey, don’t get rid of Bluey. […] Bluey is loved by mums a lot." Another explained how the show provided learning for parents: "It’s the gentle parenting, kindness, empathy for the children, the humour […] And helping kids [and] families work through real life situations with kindness and compassion." When one eight-year-old and his mum told us about their favourite shows, the following exchange took place: <blockquote> Mum:: What about Bluey? Son: I sometimes [watch it]… Mum: You don’t want to say. He doesn’t want to say he watches Bluey. Bluey’s fantastic. Son: I sometimes- Mum: He wants to be a big boy. […] Everyone in this room probably loves Bluey. It’s not just for kids. Son: Enough about that. </blockquote> Beyond families, Bluey has also attracted teen and adult fans without kids – in part thanks to a <a href="https://www.washingtonpost.com/arts-entertainment/2023/02/08/bluey-adult-fandom-tiktok/">vibrant TikTok community</a> (aka <a href="https://www.tiktok.com/search?lang=en&q=blueytok&t=1714526488575">#blueytok</a>). While some commentary suggests this adult fandom <a href="https://slate.com/culture/2024/04/bluey-the-sign-episode-ending-parents-adults-kids-disney-plus.html">is “weird”</a>, Bluey is only the latest in a long line of “children’s” shows with a passionate adult fanbase. <h2>Shifting barriers in television</h2> The distinction between “children’s” and “adult” television has long been crucial to our cultural understandings of what separates a child from an adult. In the 1950s, <a href="https://journals.sagepub.com/doi/10.1177/1749602020911359">academics were concerned</a> children were watching TV content that was too mature for them, turning them into “adultised children”, and that adults watching kids’ shows were becoming “infantile adults”. The industry took note. In 1957, a reduction in children’s TV production in the United States made space for so-called “kidult” shows designed for both age groups. Since then, the boundaries between children’s and adult television have continually shifted. In television’s early days, science fiction was associated with child audiences (which is why many initially assumed Star Trek was <a href="https://www.bloomsbury.com/au/to-boldly-go-9781838609733/">a kids’ show</a>). These boundaries were also influenced by television scheduling. Warner Bros’ early animation shorts were initially all-ages theatrical releases, but in 1960 were packaged into the Bugs Bunny Show – pitched for kids and aired on Saturday mornings. As a result, by 1967 animation was considered <a href="https://web.mit.edu/sp.778/www/Documents/From_Saturday_morning_to_---elevision_cartoons.pdf">kids’ fare</a>. The boundaries shifted again in the 1980s as adult Japanese anime such as Akira (1988) became popular in the West. In 1989, The Simpsons debuted on TV. Our research reveals even today there is confusion regarding the show’s suitability for young children. Some of our seven-to-nine-year-old participants described secretly watching it without their parents’ knowledge. <h2>Childhood healing</h2> Bluey’s adult appeal is credited to the show’s playful <a href="https://www.forbes.com/sites/paultassi/2024/04/14/disneys-giant-new-bluey-episode-the-sign-is-making-parents-cry/?sh=3c4a664f6234">yet emotionally complex</a> content. One reason adults tune into today’s kids’ TV is because it’s far more diverse than the shows they could access growing up. Take 19-year-old Bluey fan <a href="https://www.wired.com/story/bluey-internet-fandom/">Darby Rose</a>, who points to an episode in which a Jack Russell terrier has ADHD. “As a neurodivergent person myself, this representation makes me ecstatic,” Rose says. This is also true of many teen programs, with the queer-friendly high-school romance Heartstopper attracting a large <a href="https://time.com/6301556/heartstopper-netflix-season-2-fans/">adult following</a>. It’s not just <a href="https://theconversation.com/beyond-bluey-why-adults-love-re-watching-australian-kids-tv-from-their-childhoods-169727">childhood nostalgia</a> that drives adults to kids’ shows (although <a href="https://www.reddit.com/r/bluey/comments/x1xgf9/what_trips_down_memory_lane_and_nostalgia_does/">this is one aspect</a>). Watching kids’ shows can be self-affirming for adults who missed out on seeing their identity onscreen growing up. Some adult fans <a href="https://www.huffpost.com/entry/bluey-adults_n_65e774c1e4b0f9d26cac99a7">even say</a> Bluey has helped them heal childhood wounds. <h2>Children’s television meets adult fan cultures</h2> Watching “adult” television enables kids to feel more grown-up. Conversely, adults can watch children’s television to embrace aspects of their personality they feel social pressure to repress. The latter is often the case for “Bronies” (a portmanteau for “bro” and “pony”): adult male fans of the animated kids’ show My Little Pony: Friendship is Magic (2010-20). The community has attracted much <a href="https://www.mirror.co.uk/tv/tv-previews/military-men-obsessed-little-pony-6498303">controversy</a>. But <a href="https://researchportal.tuni.fi/en/publications/its-ok-to-be-joyful-my-little-pony-and-brony-masculinity">research</a> has found the reasons behind being a Brony aren’t suspicious or bizarre, but are empowering in unexpected ways. As Bronies themselves have explained, the fandom allows them to rethink what masculinity means to them, with the support of other fans online and at events such as <a href="https://www.npr.org/2019/08/14/750595032/the-friends-we-made-along-the-way-after-9-years-bronycon-calls-it-quits">BronyCon</a>. Why can’t “manliness” include watching a cute show about ponies with friendship at its heart? <h2>The changing nature of children’s television</h2> The rise of streaming has led to yet another shift. On-demand viewing means freedom from the constraints of TV scheduling, which historically set the terms for “child” and “adult” viewing. As <a href="https://www.routledge.com/Netflix-Dark-Fantastic-Genres-and-Intergenerational-Viewing-Family-Watch-Together-TV/Baker-Balanzategui-Sandars/p/book/9781032121895">our book details</a>, Netflix has invested in the expansion of cultural expectations around what makes “child-appropriate” television. Netflix’s mega hit Stranger Things deliberately pushes at these boundaries to attract a wide audience, from children and teens, to families, to adults without kids. As co-creator <a href="https://www.empireonline.com/movies/features/stranger-things-duffer-brothers-share-secrets-hit-show/">Matt Duffer explains</a>, the aim was to get children hooked on the show, and then later in the season “scare the shit out of them. Then the parents can get mad.” Parents certainly aren’t mad about their children getting hooked on Bluey. They may even be the secret to its global success: to keep the children watching, get the adults hooked.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/228610/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jessica-balanzategui-814024">Jessica Balanzategui</a>, Senior Lecturer in Media, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/djoymi-baker-1269345">Djoymi Baker</a>, Lecturer in Media and Cinema Studies, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: ABC This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

MH370 disappearance 10 years on: can we still find it

<a href="https://theconversation.com/profiles/charitha-pattiaratchi-110101">Charitha Pattiaratchi</a>, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a> It has been ten years since Malaysia Airlines passenger flight MH370 <a href="https://theconversation.com/lessons-to-learn-despite-another-report-on-missing-flight-mh370-and-still-no-explanation-100764">disappeared on March 8 2014</a>. To this day it remains one of the biggest aviation mysteries globally. It’s unthinkable that a modern Boeing 777-200ER jetliner with 239 people on board can simply vanish without any explanation. Yet multiple searches in the past decade have still not yielded the main wreckage or the bodies of the victims. At a remembrance event held earlier this week, the Malaysian transport minister announced <a href="https://www.reuters.com/world/asia-pacific/malaysia-says-mh370-search-must-go-10-years-after-plane-vanished-2024-03-03/">a renewed push for another search</a>. If approved by the Malaysian government, the survey will be conducted by United States seabed exploration firm Ocean Infinity, whose efforts were unsuccessful in 2018. <h2>What happened to MH370?</h2> The flight was scheduled to fly from Kuala Lumpur to Beijing. Air traffic control lost contact with the aircraft within 60 minutes into the flight over the South China Sea. Subsequently, it was tracked by military radar crossing the Malay Peninsula and was last located by radar over the Andaman Sea in the northeastern Indian Ocean. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=375&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=375&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=375&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=471&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=471&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579774/original/file-20240305-18-vdbysn.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=471&fit=crop&dpr=3 2262w" alt="A map of the region showing the initial search areas on 8-16 March." /></a><figcaption>The planned route, final route and initial search area for MH370 in Southeast Asia. <a class="source" href="https://en.wikipedia.org/wiki/Timeline_of_Malaysia_Airlines_Flight_370#/media/File:MH370_initial_search_Southeast_Asia.svg">Andrew Heenen/Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> Later, automated satellite communications between the aircraft and British firm’s Inmarsat telecommunications satellite indicated that the plane ended up in the southeast Indian Ocean <a href="https://hub.arcgis.com/datasets/4c94d33cfc144f7d8b78943dee56e29b/explore">along the 7th arc</a> (an arc is a series of coordinates). This became the basis for defining the initial search areas by the Australian Air Transport Safety Bureau. Initial air searches were conducted in the South China Sea and the Andaman Sea.

Google Earth/Author provided</figcaption></figure> <h2>What have searches for MH370 found so far?</h2> On March 18 2014, ten days after the disappearance of MH370, a search in the southern Indian Ocean <a href="https://www.atsb.gov.au/publications/2014/considerations-on-defining-the-search-area-mh370">was led by Australia</a>, with participation of aircraft from several countries. This search continued until April 28 and covered an area of 4,500,000 square kilometres of ocean. No debris was found. Two underwater searches of the Indian Ocean, 2,800km off the coast of Western Australia, have also failed to find any evidence of the main crash site. The initial seabed search, led by Australia, covered 120,000 square kilometres and extended 50 nautical miles across the 7th arc. It took 1,046 days and was suspended on January 17 2017. A second search by Ocean Infinity in 2018 <a href="https://oceaninfinity.com/conclusion-of-current-search-for-malaysian-airlines-flight-mh370/">covered over 112,000 square kilometres</a>. It was completed in just over three months but also didn’t locate the wreckage. <h2>What about debris?</h2> While the main crash site still hasn’t been found, several pieces of debris have washed up in the years since the flight’s disappearance. In fact, in June 2015 officials from the Australian Air Transport Safety Bureau determined that debris might arrive in Sumatra, contrary to the ocean currents in the region. The strongest current in the Indian Ocean is the South Equatorial Current. It flows east to west between northern Australia and Madagascar, and debris would be able to cross it. Indeed, on July 30 2015 a large piece of debris – a <a href="https://en.wikipedia.org/wiki/Flaperon">flaperon</a> (moving part of a plane wing) – washed up on Reunion Island in the western Indian Ocean. It was later confirmed to belong to MH370. Twelve months earlier, using an oceanographic drift model, our University of Western Australia (UWA) modelling team had predicted that any debris originating from the 7th arc would end up in the western Indian Ocean. In subsequent months, additional aircraft debris was found in the western Indian Ocean in Mauritius, Tanzania, Rodrigues, Madagascar, Mozambique and South Africa. The UWA drift analysis accurately predicted where floating debris from MH370 would beach in the western Indian Ocean. It also guided American adventurer Blaine Gibson and others to directly recover several dozen pieces of debris, three of which <a href="https://www.newsweek.com/where-blaine-gibson-now-malaysia-airlines-mh370-debris-hunter-1787369">have been confirmed</a> to be from MH370, while several others <a href="https://www.airlineratings.com/news/mh370-debris-now-for-the-facts/">are deemed likely</a>. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=602&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=602&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=602&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=757&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=757&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579756/original/file-20240305-22-q62h9n.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=757&fit=crop&dpr=3 2262w" alt="A detailed satellite map showing locations of debris found on the shores of Africa and Madagascar." /></a><figcaption>Predicted locations of landfall from results of University of Western Australia drift modelling.

The aggregation of many dots, particularly close to land, is an indication of the density of particles – higher probability of debris making landfall. These are highlighted by red circles. Charitha Pattiaratchi/UWA, Author provided</figcaption></figure> To date, these debris finds in the western Indian ocean are the only physical evidence found related to MH370. It is also independent verification that the crash occurred close to the 7th arc, as any debris would initially flow northwards and then to the west, transported by the prevailing ocean currents. These results are consistent with other drift studies undertaken by independent researchers globally. <h2>Why a new search for MH370 now?</h2> Unfortunately, the ocean is a chaotic place, and even oceanographic drift models cannot pinpoint the exact location of the crash site. The proposed new search by Ocean Infinity has significantly narrowed down the target area within latitudes 36°S and 33°S. This is approximately 50km to the south of the locations where UWA modelling indicated the release of debris along the 7th arc. If the search does not locate the wreckage, it could be extended north. Since the initial underwater searches, technology has tremendously improved. Ocean Infinity is using a fleet of autonomous underwater vehicles with improved resolution. The proposed search will also use remotely controlled surface vessels. In the area where the search is to take place, the ocean is around 4,000 metres deep. The water temperatures are 1–2°C, with low currents. This means that even after ten years, the debris field would be relatively intact. Therefore, there is a high probability that the wreckage can still be found. If a future search is successful, this would bring closure not just to the families of those who perished, but also the thousands of people who have been involved in the search efforts.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224954/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/charitha-pattiaratchi-110101">Charitha Pattiaratchi</a>, Professor of Coastal Oceanography, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

Should we still be using RATs to test for COVID? 4 key questions answered

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> We’re currently navigating <a href="https://www.thenewdaily.com.au/life/health/2023/11/15/covid-australia-eighth-wave">an eighth wave</a> of <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">COVID infections</a> in Australia. However the threat COVID poses to us is significantly less than it has ever been, thanks to immunity we’ve acquired through <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(22)00801-5/fulltext">a combination</a> of prior infection and vaccination. That said, COVID is by no means behind us. The threat of severe illness remains higher for many people, and we’re all potentially at risk of developing <a href="https://www.health.gov.au/topics/covid-19/long-covid">long COVID</a>. While many people appear to be doing fewer rapid antigen tests (RATs) than they used to – if any at all – with rising cases, and as we head towards the festive season, testing continues to be important. So what do you need to know about testing in this wave? Here are four key questions answered. <h2>1. When should I do a RAT?</h2> There are a few situations where determining your COVID status is important to inform your actions, particularly during an uptick in infections. With more circulating virus, your index of suspicion that you have COVID if you’re experiencing cold-like symptoms should be higher. RATs work best when they’re used to confirm whether you have COVID when you <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/how-testing-works-covid-19">have respiratory symptoms</a> and are infectious. So the primary use of RATs should be to determine your COVID status when you’re sick. A positive test should prompt you to isolate, and if you’re eligible, to seek antivirals. Testing might also be worthwhile if you’ve come into contact with someone with COVID but you haven’t developed symptoms. If you find you have in fact contracted the virus, you can take steps to avoid spreading it to other people (you can infect others even <a href="https://www.healthline.com/health/what-is-asymptomatic-covid#prevalence">when you’re asymptomatic</a>). This is especially important if you’re going to be socialising in large groups or in contact with people who are vulnerable. Another situation in which to consider testing, particularly at this time of year, is before attending large social gatherings. While the reliability of a RAT is never perfect, do the test as close to the event as possible, because your disease status <a href="https://www.businessinsider.com/omicron-rapid-test-hour-before-party-not-day-before-expert-2021-12">can change quickly</a>. <h2>2. Should I test multiple times?</h2> Yes. RATs are not as sensitive as PCR tests, which is the trade-off we make for being able to do this test at home and <a href="https://www.wsj.com/articles/public-health-officials-pursue-covid-19-tests-that-trade-precision-for-speed-11599562800">getting a rapid result</a>. This means that while if you test positive with a RAT you can be very confident you have COVID, if you test negative, you cannot be as confident that you don’t have COVID. That is, the test may give you a false negative result. Although RATs from different manufacturers have different accuracies, all RATs approved by Australia’s Therapeutic Goods Administration must have a sensitivity of <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia#:%7E:text=For%20rapid%20antigen%20tests%2C%20this,specificity%20of%20at%20least%2098%25.">at least 80%</a>. The way to increase your confidence in a negative result is to do multiple RATs serially – each negative test increases the confidence you can have that you don’t have COVID. If you have symptoms and have tested negative after your first RAT, <a href="https://www.fda.gov/medical-devices/safety-communications/home-covid-19-antigen-tests-take-steps-reduce-your-risk-false-negative-results-fda-safety">the advice</a> is to repeat the test after 48 hours, and potentially a third time after another 48 hours if the second test is also negative. <h2>3. Do RATs detect the latest variants?</h2> Since RATs <a href="https://www.healthdirect.gov.au/covid-19/testing#:%7E:text=Rapid%20antigen%20tests%2C%20or%20RATs,of%20proteins%20of%20the%20virus.">detect particular surface proteins</a> on SARS-CoV-2 (the virus that causes COVID), it’s theoretically possible that as the virus evolves, the reliability of these tests may be affected. However, RATs were designed to detect a part of the virus that is not as likely to mutate, so the hope is these tests <a href="https://www.health.com/do-covid-tests-work-new-variants-7967102">will continue to hold up</a> as SARS-CoV-2 evolves. The performance of RATs is continually being assessed by manufacturers. So far, there’s been no change reported in the ability of these tests to <a href="https://www.ama.com.au/articles/tga-updated-advice-rats-nearing-expiry-and-rats-efficacy-current-strains#:%7E:text=The%20TGA%20has%20received%20evidence,19%20RAT%20post%2Dmarket%20review.">detect the latest variants</a>. <h2>4. Can I rely on expired RATs?</h2> At this point in the pandemic, you might have a few expired tests at the back of your cupboard. Technically the most appropriate advice is to say you should never use a diagnostic test <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia">past its expiry date</a>. As a general principle the performance of a test cannot be guaranteed beyond this date. The risk is that over time the components of the RAT degrade and if you use a test that’s not working optimally, it’s more likely to indicate <a href="https://www.health.com/can-you-use-expired-covid-test-6827970">you don’t have COVID</a> when you actually do, which may have consequences. However, as for all things COVID, the answer is not so black and white. Since these tests were new when they were introduced earlier in the pandemic, manufacturers didn’t have specific data on their performance over time, and so the expiry dates given were necessarily conservative. It’s likely these tests will work beyond the expiry dates on the packet, but just how long and how well they work is a bit of an unknown, so we need to be cautious. The other thing to consider is ensuring you store RATs correctly. Storage instructions should be found on the packet, but the key issue is making sure they’re not exposed to extreme temperatures. In particular, <a href="https://7news.com.au/lifestyle/health-wellbeing/how-to-properly-store-your-at-home-covid-19-rapid-antigen-tests-c-5465412">high temperatures</a> may damage the chemicals in the test which may reduce its sensitivity. <h2>The path from here</h2> Regular upticks in COVID cases are something we’re going to have to get used to.

The debate: Should kids over 18 pay rent if they’re still living at home?

Parents have shared their thoughts on letting their children live at home rent free, as the age old debate of paying board stirred up some strong opinions. A <a href="https://honey.nine.com.au/money/should-children-over-the-age-of-18-pay-board-if-they-still-live-at-home-reader-poll-exclusive/77876711-2950-4bf3-bb30-716442a6fd74" target="_blank" rel="noopener">nine.com.au</a> reader survey asked the question: Should children over the age of 18 pay board if they still live at home? The responses were many and varied, as a whopping 72 percent of respondents said grown up kids should be contributing financially to the household. One person commented, "If children have employment, it's important that they clearly understand that life is not free and they need to budget, show accountability and responsibility." Another wrote, "If the children over 18 are working, then yes, they should contribute or give money to the parents to bank for them." Others said children shouldn't be expected to pay board, and would rather their kids save money for bigger financial commitments. "My parents did not charge me board even though I was working because they did not need the money and told me to save for my first car, which I did," one person shared. Another wrote their parenting tactic, writing, "I let my children not pay board. So they could save for a deposit on a house. They did and they all (3) have a house." Despite many people sharing their strong opinions on the matter, most respondents said it was not a black and white question, as many households have individual circumstances that affect their decision. "Depends on if they are working or not and what income the parents have. My son is 22 but unemployed due to health problem, we just pool our unemployment payment so it differs for each family situation, not a YES or No answer," one reader wrote. Another said it depends on their employment and study status, writing, "Yes if they're working almost full time, not if they're studying and just working part time to cover living expenses." The poll comes as Aussies have struggled with a rise in basic living costs, with <a href="https://www.finder.com.au/australian-household-spending-statistics" target="_blank" rel="noopener">ABS</a> data showing that Australian households spent a total of $1.2 trillion on what was classed as general living costs in 2022. This sum is close to $100 billion more than in 2021. The average household spent $130,353 in 2022, which is the equivalent of $2507 per week. This is a 20.4 per cent jump on the previous year.

"It's still there": Karl Stefanovic breaks silence on feud with Michael Clarke

Karl Stefanovic has broken his silence on the status of his friendship with Michael Clarke, almost one year after their infamous brawl made headlines. In December last year while on holiday in Noosa, the Today host and the former Aussie cricketer came to blows as Clarke was at the centre of a blazing row with his ex-girlfriend Jade Yarbrough and her brother-in-law Stefanovic in a public park. The expletive-ridden fight made headlines, with both men keeping relatively quiet about what eventuated from the argument. Now, Stefanovic has broken his silence on The Kyle and Jackie O Show, as Kyle Sandilands asked what the status of their friendship was. "Have you reconciled with Michael Clarke yet, your personal self, regardless of the sisters [Jade and Jasmine Yarbrough]?" Kyle asked Karl live on air. "Kyle, it's like a sticker. You rip it off but it's still there," Karl said, revealing peace had not yet been brokered between the pair. "There's still a bit of stick," Jackie O said, and Karl confirmed she was correct. "Is that like one of those stickers they put on your car when you're parked in a No Standing spot and you can't get that bastard off, when you try to pick away?" Kyle asked. "Yeah. That is really, really deep," Karl agreed with a laugh. Karl's admission comes just weeks after Michael Clarke <a href="https://oversixty.com.au/entertainment/tv/michael-clarke-breaks-silence-on-that-stoush-in-noosa-with-karl-stefanovic" target="_blank" rel="noopener">told his side</a> of the story on A Current Affair for the first time.

I've spoken about them, I haven't spoken about them." <p style="font-size: 16px; box-sizing: border-box; margin-top: 0px; margin-bottom: 1rem; caret-color: #212529; color: #212529; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji';">"For me, again, I think the most important thing is that you get out of bed every day and try and do your best.

Worried about getting a blood test? 5 tips to make them easier (and still accurate)

<a href="https://theconversation.com/profiles/sapha-shibeeb-1481231">Sapha Shibeeb</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Blood tests are a common medical procedure, offering valuable insights into a person’s health. Whether you’re getting a routine check-up, diagnosing a medical condition or monitoring treatment progress, understanding the process can make the experience more comfortable and effective. For the majority of patients, blood collections are a minor inconvenience. Others may feel <a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618506000041">uneasy and anxious</a>. Preparation strategies can help get you through the procedure. <h2>How blood is collected</h2> During venipuncture (blood draw), the phlebotomist (blood collector) inserts a needle through the skin into a vein and a small amount of blood is collected and transferred into a test tube. Tubes are sent to a laboratory, where the blood is analysed. A laboratory technician may count or examine cells and measure the levels of minerals/salts, enzymes, proteins or other substances in the sample. For some tests, blood plasma is separated out by spinning (centrifuging) the sample. Others pass a light beam through the sample to determine the amount of a chemical present. For collection, the phlebotomist usually selects a vein in the crook of your elbow, where veins are readily accessible. Blood can also be drawn from veins in the wrists, fingers or heels. A tourniquet may be applied to restrict blood flow and make the chosen vein puff out. <h2>Different tests require different preparation</h2> Before a blood test, the GP or health-care provider will give you specific instructions. These may include fasting for up to 12 hours or temporarily discontinuing certain medications. It is crucial to follow these guidelines meticulously as they can significantly impact the accuracy of your test results. For example, fasting is required before glucose (blood sugar) and lipids (blood fats) testing because blood sugar and cholesterol levels typically increase after a meal. If the blood test requires fasting, you will be asked not to eat or drink (no tea, coffee, juice or alcohol) for about eight to 12 hours. Water is allowed but smoking should be avoided because it can increase <a href="https://diabetesjournals.org/care/article/19/2/112/19825/Acute-Effect-of-Cigarette-Smoking-on-Glucose">blood sugar, cholesterol and triglyceride levels</a>. Generally, you will be asked to fast overnight and have the blood collection done in the morning. Fasting for longer than 15 hours could impact your results, too, by causing dehydration or the release of certain chemicals in the blood. If you have diabetes, you must consult your doctor prior to fasting because it can increase the risk of hypoglycemia (low blood sugar) in people with type 1 diabetes. Most type 2 diabetics can safely fast before a blood test but there are some exceptions, such as people who are taking certain medications including insulin. <h2>5 tips for a better blood test</h2> To improve your blood collection experience, consider these tips: 1. Hydrate Drink plenty of water right up to 30 minutes before your appointment. Adequate hydration improves blood flow, making your veins more accessible. Avoid <a href="https://academic.oup.com/labmed/article/34/10/736/2657269">strenuous exercise</a> before your blood test, which can increase some blood parameters (such as liver function) while decreasing others (such as sodium). 2. Loose clothing Wear clothing that allows easy access to your arms to ensure a less stressful procedure. 3. Manage anxiety If the sight of blood or the procedure makes you anxious, look away while the needle is inserted and try to keep breathing normally. Distraction can help – virtual reality has been <a href="https://pubmed.ncbi.nlm.nih.gov/31889358/">trialled</a> to reduce needle anxiety in children. You could try bringing something to read or music to listen to. 4. Know your risk of fainting If you’re prone to fainting, make sure to inform the phlebotomist when you arrive. You can have your blood drawn while lying down to minimise the risk of passing out and injury. Hydration helps maintain blood pressure and can also <a href="https://www.ahajournals.org/doi/10.1161/01.CIR.0000101966.24899.CB">reduce the risk</a> of fainting. 5. Discuss difficult veins Some people have smaller or scarred veins, often due to repeated punctures, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4989034/">chemotherapy</a> or blood thinner use. In such cases, venipuncture may require multiple attempts. It is important to talk to the phlebotomist if you feel discomfort or significant pain. A finger prick can be performed as an alternative for some tests, such as blood glucose levels. But other comprehensive tests require larger blood volume. <h2>Blood draws after lymph node removal</h2> Historically, there were concerns about drawing blood from an arm that had undergone lymph node removal. This was due to the risk of <a href="https://www.cancer.gov/about-cancer/treatment/side-effects/lymphedema/lymphedema-pdq#:%7E:text=Lymphedema%20is%20the%20build%2Dup,the%20way%20that%20it%20should.">lymphedema</a>, a condition marked by fluid build-up in the affected arm. Lymph nodes may have been removed (<a href="https://www.ncbi.nlm.nih.gov/books/NBK564397/#:%7E:text=Lymph%20node%20dissection%2C%20also%20known,surgical%20management%20of%20malignant%20tumors.">lymphadenectomy</a>) for cancer diagnosis or treatment. However, a <a href="https://ascopubs.org/doi/10.1200/JCO.2015.61.5948">2016 study</a> showed people who’ve had lymph nodes removed are not at a higher risk of developing lymphedema following blood draws, even when drawing blood from the affected arm. <h2>After your blood test</h2> The whole blood test procedure usually lasts no more than a few minutes. Afterwards, you may be asked to apply gentle pressure over a clean dressing to aid clotting and reduce swelling. If you do experience swelling, bruising or pain after a test, follow general first aid procedures to alleviate discomfort. These include applying ice to the site, resting the affected arm and, if needed, taking a pain killer. It is usually recommended you do not do heavy lifting for a few hours after a blood draw. This is to prevent surges in blood flow that could prevent clotting where the blood was taken.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/216073/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sapha-shibeeb-1481231">Sapha Shibeeb</a>, Senior lecturer in Laboratory Medicine , <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I still can't fathom it": Wendy Harmer names and shames inappropriate guest

Wendy Harmer has named and shamed the high-profile comedian who would regularly expose his genitals to her during an ongoing radio prank. Recalling the X-rated moments in her new memoir Lies My Mirror Told Me, the 68-year-old broadcasting veteran revealed that her former 2Day FM co-host, comedian Jamie Dunn would consistently expose himself as a joke. Harmer recalled how she never found the joke amusing nor sexual in nature, writing, "I suspect Jamie was a bit of a naturist." "I still can't fathom why he would do it as a gag on radio," she said, later confirming that she saw Dunn's penis "more times" than she "cared to remember". Harmer recalled the "joke" in detail, while her former co-host, Paul Holmes, also shared his experience in the memoir, saying he never understood the reasoning behind the bizarre prank. Holmes wrote, "He'd drop his dacks, exposing his penis, raise his hands in the air and strike a pose." When approached by the Sydney Morning Herald for comment, Dunn, who was best known for voicing and operating the children's puppet Agro, admitted to exposing himself "once or twice" as a "harmless joke". In her memoir, Harmer went on to detail the early days of her career in the male-dominated media industry, and shared how she very quickly learned to stand up for herself. “I was a kid, I soon developed a more assertive attitude ... Many men I have worked with have said I’m a bit scary, they’re usually the ones who got second billing,” Harmer told the Sydney Morning Herald. “Certainly, I would not like my daughter to have gone through some of the things I went through in the workplace.” Image credits: Getty Images

Will we still have antibiotics in 50 years? We asked 7 global experts

Almost since antibiotics were <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937522/#:%7E:text=Since%20the%20introduction%20in%201937,operate%20some%2070%20years%20later.">first discovered</a>, we’ve been aware bacteria can learn how to overcome these medicines, a phenomenon known as antimicrobial resistance. The World Health Organization says we’re currently <a href="https://www.who.int/news/item/20-09-2017-the-world-is-running-out-of-antibiotics-who-report-confirms">losing to the bugs</a>, with resistance increasing and too few new antibiotics in the pipeline. We wanted to know whether experts around the world think we will still have effective antibiotics in 50 years. Seven out of seven experts said yes. Lori Burrows - Biochemist, Canada Yes! Antibiotics are a crucial component of modern medicine, and we can't afford to lose them. Despite the rise of resistance in important pathogens (bugs), and the substantial decrease in new drugs in development, we have multiple tools at our disposal to protect antibiotics. Stewardship - the principle of using antibiotics only when absolutely necessary - is key to maintaining the usefulness of current antibiotics and preventing resistance to new drugs from arising. New diagnostics, such as the rapid tests that became widely available during the pandemic, can inform stewardship efforts, reducing inappropriate antibiotic use for viral diseases. Finally, researchers continue to find creative ways, including the use of powerful artificial intelligence approaches, to identify antimicrobial compounds with new targets or new modes of action. Other promising tactics include using viruses that naturally kill bacteria, stimulating the host's immune system to fight the bacteria, or combining existing antibiotics with molecules that can enhance antibiotic activity by, for example, increasing uptake or blocking resistance. André Hudson - Biochemist, United States Yes. The real question is not whether we will have antibiotics 50 years from now, but what form of antibiotics will be used. Most antibiotics we use today are modelled after natural products isolated from organisms such as fungi and plants. The use of <a href="https://news.mit.edu/2020/artificial-intelligence-identifies-new-antibiotic-0220">AI</a>, machine learning, and other <a href="https://www.theguardian.com/technology/2023/may/25/artificial-intelligence-antibiotic-deadly-superbug-hospital">computational tools</a> to help design novel, unnatural compounds that can circumvent the evolution of antibiotic resistance are only in the very early stages of development. Many of the traditional medicines such as penicillins and other common antibiotics of today which are already waning in efficacy, will probably be of very little use in 50 years. Over time, with the aid of new technology, I predict we will have new medicines to fight bacterial infections. Ray Robins-Browne - Microbiologist, Australia Yes, we will have antibiotics (by which I mean antimicrobial drugs), because people will still get infections despite advances in immunisation and other forms of prevention. Having said this, drugs of the future will be quite different from those we use today, which will have become obsolete well within the next 50 years. The new drugs will have a narrow spectrum, meaning they will be targeted directly at the specific cause of the infection, which we will determine by using rapid, point-of-care diagnostic tests, similar to the RATS we currently use to diagnose COVID. Antimicrobials of the future won’t kill bacteria or limit their growth, because this encourages the development of resistance. Instead, they will limit the ability of the bacteria to cause disease or evade our immune systems. Raúl Rivas González - Microbiologist, Spain Yes, but not without effort. Currently, antimicrobial resistance is a leading cause of death globally, and will continue to rise. But in my opinion, there will still be useful antibiotics to combat bacterial infections within 50 years. To achieve this, innovation and investment is required. Artificial intelligence may even be able to help. An example is the compound "RS102895", which eliminates the multi-resistant superbug Acinetobacter baumannii. This was identified through a machine learning algorithm. The future of antibiotics requires substantial changes in the search for new active molecules and in the design of therapies that can eliminate bacteria without developing resistance. We are on the right path. An example is the discovery of clovibactin, recently isolated from uncultured soil bacteria. Clovibactin effectively kills antibiotic-resistant gram-positive bacteria without generating detectable resistance. Future antimicrobial therapy may consist of new antibiotics, viruses that kill bacteria, specific antibodies, drugs that counter antibiotic resistance, and other new technology. Fidelma Fitzpatrick - Microbiologist, United Kingdom Yes, but not many. Without rapid scale-up of measures to curtail the "<a href="https://www.oecd.org/health/embracing-a-one-health-framework-to-fight-antimicrobial-resistance-ce44c755-en.htm">alarming global health threat</a>" of antimicrobial resistance by 2073, there will be few effective antibiotics left to treat sepsis. The <a href="https://www.cdc.gov/drugresistance/covid19.html">Centre for Disease Control</a> has indicated a reversal of progress following the pandemic, when all focus in healthcare, government and society was on COVID. Without an approach targeting people, animals, agri-food systems and the environment, antimicrobial resistance will continue its upward trajectory. <a href="https://www.worldbank.org/en/topic/health/publication/drug-resistant-infections-a-threat-to-our-economic-future">Doing nothing</a> is unacceptable – lives will be lost, healthcare expenditure will increase and workforce productivity will suffer. The highest burden of antimicrobial resistance is in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)02724-0/fulltext">low-income countries</a>. <a href="https://www.ncbi.nlm.nih.gov/books/NBK543407/">Action plans</a> exist in most OECD, European and G20 countries. In all countries plans need to be funded and implemented across all relevant sectors as above. Better integrated data to track antibiotic use and resistance across human and animal health and the environment, in addition to research and development for new antibiotics, vaccines and diagnostics, will be necessary. Juliana Côrrea - Public health expert, Brazil Yes. However, <a href="https://www.sciencedirect.com/science/article/pii/S0188440905002730?via%3Dihub">available data</a> suggest that without a shift in the political agenda towards the control and prevention of antimicrobial resistance, several antibiotics will have lost their utility. The problem of bacterial resistance is not new and the risk of antibiotics becoming ineffective in the face of the evolutionary capacity of bacteria is one of the main problems facing global health. The creation of policies to promote the appropriate use of this resource has not progressed at the same speed as inappropriate use in human and animal health and in agricultural production. The factors that impact antibiotic use are complex and vary according to local contexts. The response to the problem goes far beyond controlling use at the individual level. We must recognise the social, political, and economic dimensions in proposing more effective governance. Yori Yuliandra - Pharmacist, Indonesia Yes. Despite their <a href="https://www.who.int/news-room/fact-sheets/detail/antimicrobial-resistance">reduced efficacy over time</a>, antibiotics continue to be produced every year. Researchers are tirelessly working to develop new and more effective antibiotics. And researchers are actively exploring combinations of antibiotics to enhance their efficacy. While antimicrobial resistance is rising, researchers have been making remarkable progress in addressing this issue. They have developed innovative antibiotic classes such as <a href="https://doi.org/10.4155/fmc-2016-0041">FtsZ inhibitors</a> which can inhibit cell division, a process necessary for bacteria to multiply. <a href="https://www.who.int/publications/i/item/9789240021303">Clinical trials</a> are currently taking place. A deeper understanding of the molecular aspects of bacterial resistance has led to the discovery of new treatment strategies, such as the <a href="https://doi.org/10.1039/D2MD00263A">inhibition of key enzymes</a> that play a pivotal role in bugs becoming resistant. And <a href="https://doi.org/10.1038/s42003-021-02586-0">advances in computer technology</a> have greatly accelerated drug discovery and development efforts, offering hope for the rapid discovery of new antibiotics and treatment strategies.

“She’s still with us, but it won’t be long": Hughesy's heartbreaking family news

Dave 'Hughesy' Hughes has held back tears as he shared the heartbreaking details of his mum's health battle live on his radio show. Speaking candidly on 2Day FM’s Hughesy, Ed & Erin, Hughesy shared that it had been a "tough few weeks" for his family as his mum, Carmel, was nearing the end of her life. “My mum’s unwell, and the family have gathered around her, and we’re celebrating her life,” Hughesy told co-hosts Erin Molan and Ed Kavalee. “She’s still with us, but it won’t be long. She’s a beautiful woman who’s been a great matriarch of the family, and we’re all around her at the moment.” While holding back tears, Hughesy then revealed that “she’s asleep now and she probably won’t wake up again”. He explained the family had been “going through photos” recently in celebration of Carmel’s life. “Mum grew up in an orphanage, and there’s a photo of her teaching a class with nuns looking over her … She had to leave the orphanage because she didn’t want to be a teacher, so she left with nothing and went and became a nurse, and met Dad.” Reflecting on his mother’s legacy during the segment on Friday, Hughesy told his co-hosts: “She’s been a beautiful mother, who really supports her children.” He went on: “Everyone goes through [losing their parents] … but the memories of all the sacrifice, and all the good times … She’s done so well in her life. We’ll miss her a lot. “She’s always been stoic and never complained.” Despite the difficult time Hughesy and his family are going through, the comedian was still able to smile and laugh as he reflected on his mum's sense of humour that she has kept "until the end". “We were around and didn’t think she could even speak again, and one of the nurses was lifting her and said, ‘I’m sorry if I drop you’, and Mum just whispered, ‘it doesn't matter now’, and made the nurse laugh.” “So she was still coming out with zingers … she’s a beautiful woman.” Image credits: Instagram

The United Kingdom has also seen a <a href="https://twitter.com/DrEricDing/status/1702790082749448202?t=FLc5f9FoMS6ksioFS8ATpA&s=09">significant increase</a> in adult and child hospitalisations due to COVID in the past month. In Australia, more than <a href="https://www.worldometers.info/coronavirus/country/australia/">5,000 people</a> have died due to COVID so far this year. Excess deaths from any cause are <a href="https://www.abs.gov.au/statistics/health/causes-death/provisional-mortality-statistics/latest-release">13% higher</a> than expected. We expect many of these are related to COVID. The median age of COVID deaths is <a href="https://www.abs.gov.au/articles/covid-19-mortality-australia-deaths-registered-until-31-july-2023">around 85 years old</a> in Australia. But there were 267 reported deaths in people under 50 until the end of July 2023; some may have had weaker immune systems. The impacts of <a href="https://www.aph.gov.au/longandrepeatedcovid">long COVID and re-infections</a> are significant, which <a href="https://www.abc.net.au/news/2022-07-20/younger-active-female-data-reveals-long-covid-profile/101251352">one study shows</a> mainly affects people of working age and most commonly women. <h2>I’ve had a booster. Does that still protect me?</h2> We know immunity from COVID vaccines wanes over time. In a paper published in May, a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2804451?utm_source=For_The_Media&utm_medium=referral&utm_campaign=ftm_links&utm_term=050323">systematic review</a> of 40 studies showed by how much. Protection by the first two doses of the vaccine (known as the primary series) against symptomatic infection from Omicron waned from almost 53% one month after the second dose to just over 14% after six months. The same review found a booster (third or fourth dose) increased protective immunity to the same levels as the primary series. However, that immunity waned to just 30% nine months later. A number of studies have shown protection against severe disease and death from the Omicron variant also wanes over time. For example, <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(23)00365-1/fulltext#seccestitle10">a UK study</a> found a primary series plus a bivalent booster (targets two strains) provided 53% protection against hospitalisation four weeks after the booster among people aged 50 or over. Protection dropped to 36% at ten weeks. An <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4445191">Australian study</a>, yet to be independently verified by other researchers, suggests protection against death from COVID also wanes. Of 3.8 million adults over 65 years, protection of a third dose booster against death from COVID waned from an estimated 93% within three months to 56% after six months. So we believe a reasonable interpetation of the above data is to recommend a booster every six months in people aged 75 and older, and younger people with impaired immune systems. But in Australia, just over <a href="https://www.health.gov.au/sites/default/files/2023-09/covid-19-vaccine-rollout-update-15-september-2023.pdf">50%</a> of people aged 75 or older have received a booster in the past six months; only about 38% of people aged 65-74 and about 9% in those aged 18-64 years. <h2>I’ve had COVID recently. Surely that’s enough</h2> There is a widespread perception that if you’ve been infected with COVID and have had the primary series of the vaccine then you’re immune and, therefore, don’t need to get a booster. This is commonly described as having “hybrid immunity”. However, a very <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)02465-5/fulltext">large study</a> across 19 countries found infection conferred different levels of immunity, depending on the variant. While infection with COVID effectively protected against reinfection by the original, Alpha, Beta and Delta variants, this was much less effective against the Omicron BA.1 variant. Since BA.1, there have been many new sub-variants that are even more adept at evading immunity. <h2>Who can get a booster?</h2> Earlier this month, the Australian Technical Advisory Group on Immunisation (ATAGI) <a href="https://www.health.gov.au/news/atagi-update-on-the-covid-19-vaccination-program">recommended</a> all adults aged 75 or older “should receive” an additional dose of the bivalent vaccine if six months have passed since their last dose. Additionally, people aged 65-74 and immunocompromised younger adults should “consider” an additional dose. ATAGI argues that the baseline risk of severe illness in people under 65 is low if they have already been vaccinated, and particularly if they have also been infected. So, a further 2023 dose for this group would offer little additional benefit, even if it has been more than six months since their last dose. The US has taken a different approach. Last week, the Centers for Disease Control and Prevention <a href="https://www.cdc.gov/media/releases/2023/p0912-COVID-19-Vaccine.html">recommended</a> all people over six months who have not received a COVID vaccine in the previous two months should get a dose of the newly approved monovalent (single strain) vaccines. These have been developed by Pfizer and Moderna to specifically <a href="https://www.fda.gov/news-events/press-announcements/fda-takes-action-updated-mrna-covid-19-vaccines-better-protect-against-currently-circulating">target the XBB.1.5</a> sub-variant of Omicron. <a href="https://www.canada.ca/en/health-canada/news/2023/09/health-canada-authorizes-moderna-covid-19-vaccine-targeting-the-omicron-xbb15-subvariant.html">Health Canada</a> has adopted similar recommendations. These new monovalent vaccines are expected <a href="https://www.science.org/content/article/should-i-get-covid-19-booster">to be effective</a> in preventing infection by recently emerging Omicron sub-variants, such as EG.5 and FL.1.51 derived from the XBB.1.5 sub-variant, and the newer highly mutated <a href="https://www.gov.uk/government/publications/investigation-of-sars-cov-2-variants-of-concern-variant-risk-assessments/risk-assessment-for-sars-cov-2-variant-v-23aug-01-or-ba286">BA.2.86</a>, which arose from an earlier sub-variant and is a significant evolutionary leap. While Canada and the US move into the northern hemisphere winter, Australians should not believe they are at lower risk during the summer. After all, <a href="https://www.worldometers.info/coronavirus/country/australia/">two large COVID waves</a> in Australia were in the summers of 2021/22 and 2022/23. Monovalent XBB.1.5 vaccines are not yet available in Australia, but are being evaluated by the <a href="https://www.tga.gov.au/products/covid-19/covid-19-vaccines/covid-19-vaccines-regulatory-status">Therapeutic Goods Administration</a>. So, in the future, Australia’s advice about who’s eligible for a booster, and which type of booster, may change. <h2>So, how do I decide if I need a booster now?</h2> There is evidence in Australia of <a href="https://www.abc.net.au/news/2023-09-21/new-covid-strain-variant-pirola-ba-2-86-in-australia-symptoms/102873304">growth of</a> the newer subvariants, including the detection of BA.2.86. So all Australians aged 75 and over who have not had a booster in the past six months should immediately have the currently available bivalent vaccine. Younger age groups may wait until further ATAGI advice about the new monovalent vaccines. <h2>COVID is not over</h2> While there is no need for alarm, Australians need to be aware of the ongoing significant impacts of COVID. The SARS-CoV-2 virus is still a formidable foe as it continues to mutate. COVID vaccines will be <a href="https://www.pm.gov.au/media/improving-future-preparedness-inquiry-response-covid-19-pandemic">among the topics</a> the newly announced inquiry will investigate. But we cannot rely on vaccines alone. Avoiding (re)infection is also vital. Breathe <a href="https://www.coronavirus.vic.gov.au/ventilation">clean indoor air</a>, wear <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/types-of-masks.html">high quality masks</a> and get tested so you can access <a href="https://www.health.gov.au/health-alerts/covid-19/treatments/eligibility">antivirals</a> if eligible.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/213469/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michael-toole-18259">Michael Toole</a>, Associate Principal Research Fellow, <a href="https://theconversation.com/institutions/burnet-institute-992">Burnet Institute</a>; <a href="https://theconversation.com/profiles/heidi-drummer-1472642">Heidi Drummer</a>, Professor and Co-Program Director, Disease Elimination, <a href="https://theconversation.com/institutions/burnet-institute-992">Burnet Institute</a>, and <a href="https://theconversation.com/profiles/suman-majumdar-117988">Suman Majumdar</a>, Associate Professor and Chief Health Officer - COVID and Health Emergencies, <a href="https://theconversation.com/institutions/burnet-institute-992">Burnet Institute</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
