What is methanol? How does it get into drinks and cause harm?

It means methanol is processed differently in our bodies and is much more toxic than ethanol.</p> <p>Methanol is used in a <a href="https://pubchem.ncbi.nlm.nih.gov/compound/Methanol">variety of industrial and household products</a>, such as windshield cleaning fluids, antifreeze and fuel. It’s not safe for human consumption.</p> <h2>What makes methanol toxic?</h2> <p>The difference is in how methanol is metabolised, or broken down in our bodies.</p> <p>Ethanol is metabolised into a chemical compound called acetaldehyde. Acetaldehyde is toxic, but is rapidly converted to acetate (also known as acetic acid, found in vinegar). Generating an acid may sound bad, but acetate actually <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6699882/">produces energy and makes important molecules</a> in the body.</p> <p>By contrast, methanol is metabolised into <a href="https://www.cancer.gov/about-cancer/causes-prevention/risk/substances/formaldehyde">formaldehyde</a> (a chemical used in <a href="https://www.safework.nsw.gov.au/hazards-a-z/hazardous-chemical/priority-chemicals/formaldehyde">industrial glues</a> and for embalming corpses, for example) and then to <a href="https://pubchem.ncbi.nlm.nih.gov/compound/Formic-Acid">formic acid</a> (the chemical in some ant bites that makes them hurt so much).</p> <p>Unlike acetate, which the body uses, formic acid <a href="https://pubmed.ncbi.nlm.nih.gov/1665561/">poisons the mitochondria</a>, the powerhouses of the cells.</p> <p>As a result, a person exposed to methanol can go into severe <a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">metabolic acidosis</a>, which is when too much acid builds up in the body.</p> <p>Methanol poisoning can cause nausea, vomiting, and abdominal pain. The acidosis then causes depression of the central nervous system which can cause people with methanol poisoning to fall unconscious and go into a coma, as well as retinal damage leading to vision loss. This is because the retinas are full of active mitochondria and sensitive to them being damaged.</p> <p>Death is not inevitable if only a small amount of methanol has been consumed, and rapid treatment will greatly reduce damage.</p> <p>However, permanent vision damage can occur even at <a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">non-lethal doses</a> if treatment is not administered quickly.</p> <h2>What does treatment involve?</h2> <p><a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">Treatment</a> is mainly supportive care, such as intubation and mechanical ventilation to help the patient to breathe.</p> <p>But it can also involve drugs such as <a href="https://go.drugbank.com/drugs/DB01213">fomepizole</a> (which inhibits the generation of toxic formic acid) and dialysis to remove methanol and its metabolites from the body.</p> <h2>How does methanol get into alcoholic drinks?</h2> <p>Methanol can turn up in any alcoholic beverage, but it’s most likely in beverages with higher alcohol content, such as spirits, and traditionally brewed drinks, such as fruit wines.</p> <p>Methanol can get into alcoholic beverages in a number of ways. Sometimes it’s added <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8303512/">deliberately and illegally</a> during or after manufacturing as a cheaper way to increase the alcohol content in a drink.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5028366/">Traditional brewing methods</a> can also inadvertently generate methanol as well as ethanol and produce toxic levels of methanol depending on the microbes and the types of plant materials used in the fermentation process.</p> <p>We don’t yet know how the Australian teenagers came to be poisoned in this tragedy. But it is a good idea when travelling (particularly in areas with traditionally fremented drinks, such as south-east Asia, the Indian subcontinent and parts of Africa) to always be careful.</p> <p>The Australian government’s <a href="https://www.smartraveller.gov.au/before-you-go/safety/partying#methanol">Smartraveller website</a> advises that to avoid methanol poisoning you should be careful drinking cocktails and drinks made with spirits, drink only at reputable licensed premises and avoid home-made alcoholic drinks.</p> <p>Drinking only mass-produced commercial brews can be safer, though understandably people often want to try locally made drinks as part of their adventure.<!-- Below is The Conversation's page counter tag.

Alan Jones once seemed unassailable. What ended it was a peculiarly Sydney story of media, politics and power

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/denis-muller-1865">Denis Muller</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>For decades it seemed Alan Jones was unassailable.</p> <p>A finding against him of professional misconduct by the Australian Broadcasting Authority (2000); a <a href="https://www.smh.com.au/entertainment/tv-and-radio/tribunal-upholds-that-jones-incited-hatred-20121002-26x8h.html">finding</a> that he incited hatred, serious contempt and severe ridicule of Lebanese Muslims (2009); propositions of violence against two women prime ministers (<a href="https://www.abc.net.au/news/2011-10-20/alan-jones-says-gillard-remark-best-left-unsaid/3579658">2011</a> and <a href="https://www.abc.net.au/news/2020-05-21/alan-jones-breached-rules-in-jacinda-ardern-comment/12271476">2019</a>); verdicts against him and his employer amounting to millions of dollars in defamation actions (most notably <a href="https://www.abc.net.au/news/2018-09-12/alan-jones-defamed-wagners-court-decision-brisbane-qld/10230384">one for $3.75 million</a> in 2018): none of these ended his career.</p> <p>Quite the reverse. Only weeks after the Australian Broadcasting Authority found in its “cash for comments” inquiry that Jones and others had misled their listeners by presenting paid endorsements as editorial opinion, he was hosting an event for then prime minister John Howard.</p> <p>Howard was to become a fixture on the Jones program throughout the 11 years of his prime ministership.</p> <p>The day after the Australian Communications and Media Authority found Jones was likely to have encouraged violence and vilification of Australians of Lebanese and Middle Eastern background, Howard <a href="https://www.theage.com.au/national/jones-wins-friends-in-high-places-20070412-ge4n4f.html">described him</a> as “an outstanding broadcaster”. “I don’t think he’s a person who encourages prejudice in the Australian community, not for one moment, but he is a person who articulates what a lot of people think.”</p> <p>By 2001, Jones had become a kind of on-air policy-maker for the New South Wales government. In November that year, he dined with the then Labor premier, Bob Carr. They discussed a range of government policies, particularly policing. At that time, Jones was a relentless critic of the NSW police.</p> <p>The following week, <a href="https://www.abc.net.au/news/2012-10-01/newton-alan-jones/4288824">Carr dispatched</a> his police minister-designate, Michael Costa, to Jones’s home to discuss policing policy.</p> <p>In 2011 he said Julia Gillard, then Australia’s prime minister, should be taken out to sea and dumped in a chaff bag. In August 2019 he said Scott Morrison, who was then Australia’s prime minister, should “shove a sock” down the throat of his New Zealand counterpart Jacinda Ardern.</p> <p>He was an outspoken climate-change denier, and these grotesqueries were part of his campaign against political recognition of this reality.</p> <figure><iframe src="https://www.youtube.com/embed/Od6I1YbrBoM?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Jones’s power, which made him so apparently untouchable, came from his weaponising of the microphone for conservative political ends in ways that resonated with his vast and rusted-on audience of largely working-class older people across Sydney’s sprawling western suburbs.</p> <p>These suburbs contain many marginal state and federal electorates where the fates of governments can be decided. Their populations provide fertile ground for seeding by right-wing radio shock jocks, of whom Jones and his rival John Laws were pre-eminent examples.</p> <p>In Australia, this is a peculiarly Sydney phenomenon. It is not seen to the same degree in any other capital city, even though they too have large areas of socioeconomic disadvantage like western Sydney.</p> <p>Why that should be so is a complex question, but there are aspects of Sydney life that mark it out as different. It is really two cities. One is the largely prosperous and scenically dazzling east and north. The other, much larger, consists of dreary tracts of increasingly crowded housing stretching for many kilometres to the west and southwest.</p> <p>In Sydney argot, the inhabitants of these respective worlds are called “silvertails” and “fibros”, the latter referring to the cladding of the homes that proliferated in western Sydney between and after the two world wars.</p> <p>This two-cities effect makes the gap between the “haves” and the “have-nots” highly visible in a way that has no parallel in other Australian capitals. It engenders deep-seated grievance and cynicism, which the likes of Jones, who lives in a multimillion-dollar apartment on Circular Quay, have relentlessly exploited.</p> <p>Jones coined the term “Struggle Street” to encapsulate the hardships of his listeners’ lives.</p> <p>To these powerless people, Jones and Laws gave a voice, and as their audiences grew, prime ministers and premiers courted and feared them.</p> <p>In the end, Jones’s impregnability was breached by not the power elite turning on one of their own, but by the journalism of a redoubtably tenacious Sydney Morning Herald investigative reporter, Kate McClymont.</p> <p>In December 2023, <a href="https://www.smh.com.au/national/he-d-go-the-grope-alan-jones-accused-of-indecently-assaulting-young-men-20231205-p5epai.html">she claimed</a> Jones had used his position of power, first as a teacher and later as the country’s top-rating radio broadcaster, to allegedly prey on a number of young men.</p> <p>In response to McClymont’s work, the NSW police set up Strike Force Bonnefin, run by the State Crime Command’s Child Abuse Squad, to conduct an investigation into Jones.</p> <figure><iframe src="https://www.youtube.com/embed/0ExkpCtfmA8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>On November 18 2024, Jones was arrested at his Circular Quay home and charged initially with 24 sexual offences against eight males. The following day, two <a href="https://www.abc.net.au/news/2024-11-19/alan-jones-charged-with-additional-offences-nsw-police/104617680">additional charges</a> were laid involving a ninth male.</p> <p>Through his lawyers, Jones has denied the charges and was bailed to appear in Sydney’s Downing Centre Local Court on December 18. He <a href="https://www.smh.com.au/national/alan-jones-arrested-over-allegations-he-indecently-assaulted-young-men-20241118-p5krdu.html">was ordered</a> to surrender his passport and not to contact or harass the alleged victims.</p> <p>The charges relate to offences alleged to have been committed by Jones between 2001 and 2019, the youngest alleged victim being 17 at the time.</p> <p>Those dates coincide almost exactly with Jones’s most influential years, from 2002 to 2020.</p> <p>McClymont <a href="https://www.smh.com.au/national/a-stunning-development-kate-mcclymont-on-alan-jones-arrest-and-what-s-next-20241118-p5krln.html">has spoken</a> about the reluctance of some of her interviewees to speak, for fear of what Jones might do: "People were too afraid to take on Alan Jones.

This may create some difficulties in the presence of grandchildren or when cleaning the doll.</p> <p>The introduction of child representation therapy may also require additional staff training and time.

What causes the itch in mozzie bites? And why do some people get such a bad reaction?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting?</p> <p>Female mosquitoes <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-ento-120811-153618">need blood</a> to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse.</p> <p>So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others?</p> <h2>What happens when a mosquito bites?</h2> <p>Mosquitoes are attracted to warm blooded animals, including us. They’re attracted to the <a href="https://www.cambridge.org/core/journals/bulletin-of-entomological-research/article/abs/role-of-carbon-dioxide-in-hostfinding-by-mosquitoes-diptera-culicidae-a-review/2506B86EF63852B2D02EC3FCEE1E3B8B">carbon dioxide</a> we exhale, our body temperatures and, most importantly, <a href="https://www.abc.net.au/news/2024-11-08/mosquitoes-climate-change-skin/104548122">the smell of our skin</a>.</p> <p>The <a href="https://www.cell.com/trends/parasitology/abstract/S1471-4922(21)00237-3">chemical cocktail</a> of odours from bacteria and sweat on our skin <a href="https://www.cell.com/current-biology/fulltext/S0960-9822(23)00532-8">sends out a signal</a> to hungry mosquitoes.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S2667114X21000522">Some people’s</a> skin smells more appealing to mosquitoes, and they’re more likely to be bitten than others.</p> <p>Once the mosquito has made its way to your skin, things get a little gross.</p> <p>The mosquito pierces your skin with their “proboscis”, their feeding mouth part. But the proboscis isn’t a single, straight, needle-like tube. There are multiple tubes, <a href="https://www.npr.org/sections/health-shots/2016/06/07/480653821/watch-mosquitoes-use-6-needles-to-suck-your-blood">some designed</a> for sucking and some for spitting.</p> <p>Once their mouth parts have been inserted into your skin, the mosquito will inject some saliva. This contains a mix of chemicals that gets the blood flowing better.</p> <p>There has even been a suggestion that future medicines could be inspired by the <a href="https://www.sydney.edu.au/news-opinion/news/2018/03/29/mosquito-saliva-vital-to-the-discovery-of-future-drugs.html">anti-blood clotting properties</a> of mosquito saliva.</p> <p>It’s not the stabbing of our skin by the mosquito’s mouth parts that hurts, it’s the mozzie spit our bodies don’t like.</p> <h2>Are some people allergic to mosquito spit?</h2> <p>Once a mosquito has injected their saliva into our skin, a variety of reactions can follow. For the lucky few, nothing much happens at all.</p> <p>For most people, and irrespective of the type of mosquito biting, <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2022.1024559/full">there is some kind of reaction</a>. Typically there is <a href="https://www.sciencedirect.com/science/article/abs/pii/S0161589023002304?via%3Dihub">redness and swelling of the skin</a> that appears within a few hours, but often more quickly, after just a few minutes.</p> <p>Occasionally, the reaction can cause pain or discomfort. Then comes the <a href="https://www.abc.net.au/news/health/2023-01-20/mosquito-bites-itchy-calamine-heat-ice-antihistamine-toothpaste/101652608">itchiness</a>.</p> <p>Some people do suffer severe reactions to mosquito bites. It’s a condition often referred to as “<a href="https://www.webmd.com/allergies/what-is-skeeter-syndrome">skeeter syndrome</a>” and is an allergic reaction caused by the protein in the mosquito’s saliva. This can cause large areas of swelling, blistering and fever.</p> <p>The chemistry of mosquito spit hasn’t really been well studied. But it has been shown that, for those who do suffer allergic reactions to their bites, the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0091674904022183">reactions may differ</a> depending on the type of mosquito biting.</p> <p>We all probably get more tolerant of mosquito bites as we get older. Young children are certainly more likely to suffer more following mosquito bites. But as we get older, the reactions are less severe and may pass quickly without too much notice.</p> <h2>How best to treat the bites?</h2> <p>Research into treating bites <a href="https://linkinghub.elsevier.com/retrieve/pii/S0161589023002304">has yet to provide</a> a single easy solution.</p> <p>There are many <a href="https://www.healthline.com/health/outdoor-health/home-remedies-for-mosquito-bites">myths and home remedies</a> about what works. But there is little scientific evidence supporting their use.</p> <p>The best way to treat mosquito bites is by applying a cold pack to reduce swelling and to keep the skin clean to avoid any secondary infections. Antiseptic creams and lotions may also help.</p> <p>There is some evidence that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10309056/">heat may alleviate</a> some of the discomfort.</p> <p>It’s particularly tough to keep young children from scratching at the bite and breaking the skin. This can form a nasty scab that may end up being worse than the bite itself.</p> <p>Applying an anti-itch cream may help. If the reactions are severe, <a href="https://www.healthdirect.gov.au/insect-bites-and-stings">antihistamine medications</a> may be required.</p> <h2>To save the scratching, stop the bites</h2> <p>Of course, it’s better not to be bitten by mosquitoes in the first place. Topical <a href="https://theconversation.com/insect-repellents-work-but-there-are-other-ways-to-beat-mosquitoes-without-getting-sticky-171805">insect repellents</a> are a safe, effective and affordable way to reduce mosquito bites.</p> <p>Covering up with loose fitted long sleeved shirts, long pants and covered shoes also provides a physical barrier.</p> <p><a href="https://theconversation.com/are-mosquito-coils-good-or-bad-for-our-health-88548">Mosquito coils and other devices</a> can also assist, but should not be entirely relied on to stop bites.</p> <p>There’s another important reason to avoid mosquito bites: millions of people around the world suffer from mosquito-borne diseases. More than <a href="https://www.who.int/news-room/fact-sheets/detail/malaria">half a million people die</a> from malaria each year.</p> <p>In Australia, <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005070">Ross River virus</a> infects more than 5,000 people every year. And in recent years, there have been cases of serious illnesses caused by <a href="https://www.science.org/content/article/how-rains-pigs-and-waterbirds-fueled-shocking-disease-outbreak-australia">Japanese encephalitis</a> and <a href="https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2023.1256149/full">Murray Valley encephalitis</a> viruses.<!-- End of code.

Readers response: What was the worst hotel experience you had?

<p>We asked our readers to share their stories of the worst hotel experience that have endured while on holiday, and the response was overwhelming. Here's what they said. </p> <p><strong>Deedee Cullum</strong> - At a 5 star in Beijing. Arrived from the airport after 1am. Let into the room to find it occupied with someone having a bath. Instead of changing our room we waited in the lobby for 1 and 1/2 hours while they changed to the correct room and cleaned ours. The wet towels were neatly folded on the towel rack and the used soap was on the basin. When I turned the bedside light on I got a shock. To be fair management were most apologetic and gave us free dining in their top restaurant for the 4 days we were there. It was a few years ago but never forgotten.</p> <p><strong>Bruce Hopkins</strong> - I stopped at a Hotel in Hobart, arrived in the afternoon, checked out the next day, the whole time I stopped there, I never saw anyone on reception or any staff at all. Creepiest hotel I stayed in.</p> <p><strong>Carol Henwood</strong> - When we went to have a shower, and the towels disintegrated! The shower had black mould in all the corners. The carpet was so sticky, we kept our shoes on.  We slept on top of the bed as the sheets were crumpled and smelly. What a night.</p> <p><strong>Sheila Kell </strong>- When my eldest son was about 2 years old we took a holiday to Shute Harbour in QLD and in middle of night we heard lots of scratching so turned on light and sat up in bed and there were hundreds of field mice crawling up walls and back of bed. They apparently were having a plague, but we dressed and left. Couldn't sleep in that motel.</p> <p><strong>Christine Warner</strong> - A country pub only option one night. Our room has no lock on the door, and there were gaps in the floorboards so we could see straight down to the bar where it was very noisy. We had already been warned of people breaking in to hotel and motel rooms in that region, so we slept in the car and returned to the room in the morning for a shower.</p> <p><strong>Helen Wilson</strong> - In Singapore, they gave us a “free” breakfast while someone rummaged through our belongings and took stuff.</p> <p><em>Image credits: Shutterstock </em></p> <p> </p>

What’s the difference between MSG and table salt? A chemist explains

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>It’s dinner time. You’ve worked hard to prepare a nutritious and tasty meal. But after taking your first bite you feel something is missing. Perhaps you should have added more salt? Pepper? Or maybe even something more exotic like monosodium glutamate, better known as MSG?</p> <p>There are many <a href="https://theconversation.com/explainer-what-are-e-numbers-and-should-you-avoid-them-in-your-diet-43908">food additives</a> used in both home cooking and commercial products. These ingredients improve the flavour, smell, texture, appearance and longevity of foods.</p> <p>Salt and MSG are two well-known food additives. Both contain sodium, but there are plenty of differences which you can use to your benefit.</p> <h2>What is a salt?</h2> <p>Salts are made of positively and negatively charged components called ions. Salts generally dissolve in water, and are brittle. The names of salts often feature a metal (positively charged) followed by a non-metal (negatively charged).</p> <p>The common kitchen ingredient we call “salt” is just one type of salt. To distinguish it from all other salts, we should more specifically refer to it as “table salt”. Chemically, it’s sodium chloride.</p> <h2>Sodium chloride</h2> <p>After the quick chemistry lesson above, we can see that table salt, sodium chloride, contains a positively charged sodium and a negatively charged chlorine.</p> <p>These charged components are arranged in crystals of salt in a regular repeating pattern. Each sodium ion is surrounded by six chloride ions and each chloride ion is surrounded by six sodium ions. This arrangement gives the crystal a “cubic” form. If you look closely at salt, you may see cube-shaped crystals.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">The chemical structure of table salt forms a cube of sodium and chloride ions.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/sodium-chloride-nacl-structure-ionic-crystal-2417242373">Sandip Neogi/Shutterstock</a></span></figcaption></figure> <p>Sodium chloride is very abundant. It is found <a href="https://theconversation.com/i-have-always-wondered-why-is-the-sea-salty-83489">dissolved in Earth’s oceans</a>. Mineral deposits of salt, known as halite or rock salt, formed from the evaporation and crystallisation of ancient seas.</p> <p>Depending on the source, the salt may contain many other trace minerals that can even add colour to it, such as the pink-coloured Himalayan salt from Pakistan. Salt can also be fortified with <a href="https://www.who.int/publications/i/item/9789240053717">sodium iodide</a> as a public health measure.</p> <p>Describing the taste of salt is quite difficult without using the word “salty”. It’s a very common food additive, as it is so abundant and versatile. It is an essential ingredient for many traditional food preservation techniques for meats (pork and fish), vegetables (kimchi, sauerkraut and pickles), and dairy (cheese and butter).</p> <p>Salt is considered a universal flavouring agent. It can mask bitter flavours and bring out sweet, sour and <a href="https://theconversation.com/the-asian-roots-of-umami-the-fifth-taste-central-to-thanksgiving-fare-50699">umami</a> (savoury) ones.</p> <p>Despite popular depictions of <a href="https://theconversation.com/that-neat-and-tidy-map-of-tastes-on-the-tongue-you-learned-in-school-is-all-wrong-44217">taste maps</a>, there is no one place on the tongue where we taste salt. Other sodium salts can also give a “salty” taste, but the effect declines (and can even turn to bitter) with negatively charged components other than chloride.</p> <h2>MSG or monosodium glutamate</h2> <p>Monosodium glutamate is also a salt. The glutamate is the negatively charged form of glutamic acid, an amino acid that is found in nature as a building block of proteins.</p> <p>MSG, and more generally glutamates, are found in a wide range of foods including tomatoes, Parmesan cheese, soy sauce, dried seaweeds, Worcestershire sauce and protein-rich foods. All of these foods impart umami flavours, which are described as savoury or meaty.</p> <p>Commercial MSG is not extracted from the environment but produced by bacterial fermentation. Glucose is converted to glutamic acid, which is further processed by adding sodium hydroxide to form MSG (and water).</p> <p>MSG is sold as crystals, but they have a long, prismatic shape rather than the cubic form of sodium chloride. It’s worth tasting a few crystals of MSG directly to experience the native taste of umami.</p> <p>Despite decades of bad press and concern, <a href="https://theconversation.com/msg-is-back-is-the-idea-its-bad-for-us-just-a-myth-or-food-science-237871">MSG is considered safe</a> to consume in the concentrations typically found in or added to foods.</p> <p>Table salt and MSG both contain sodium, but at different percentages of the total weight: table salt has around 40% sodium, versus just 14% in MSG. You are also more likely to be routinely adding table salt to your food rather than MSG.</p> <p>Eating too much sodium is well known to be unhealthy. <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">Potassium-enriched substitutes</a> have been suggested for a range of health benefits.</p> <h2>A flavour enhancer</h2> <p>The flavour of MSG can be elevated further by combining it with other food additives, known as sodium ribonucleotides.</p> <p>Japanese and Korean cooks figured this secret out long before chemists, as boiling dried fish and seaweed produces foundation stocks (dashi) containing a mix of naturally sourced glutamates and ribonucleotides.</p> <p>Ribonucleotides are classified as “generally considered as safe” by <a href="https://www.cfsanappsexternal.fda.gov/scripts/fdcc/index.cfm?set=FoodSubstances&amp;id=DISODIUMINOSINATE&amp;sort=Sortterm_ID&amp;order=ASC&amp;startrow=1&amp;type=basic&amp;search=disodium">food standards authorities</a>. Humans consume many grams of the natural equivalent in their diets.</p> <p>What can be more problematic are the carbohydrates- and fat-rich foods that have their flavours enhanced, which can potentially lead us to eat excessive calories.</p> <p>The combination of MSG and ribonucleotides produces a more-ish sensation. Next time you see a bag of potato chips or instant noodles, have a quick look to see if it contains both MSG (E621) and a ribonucleotide source (E627–E635).</p> <p>I personally keep a jar of MSG in my kitchen. A little goes a long way to elevate a soup, stew or sauce that isn’t quite tasting the way you want it to, but without adding too much extra sodium.<!-- Below is The Conversation's page counter tag.

Readers response: What’s the best advice you’ve received on staying healthy as you age?

<p>We asked our readers what the best advice they’ve received on staying healthy as you age is, and the response was overwhelming. Here's what they said. </p> <p><strong>Fred Pilcher </strong>- Don't smoke. That's the most important advice you're likely to get. If you do smoke, quit now. Today. I've lost parents and friends to lung cancer and emphysema - both terrible ways to go. (I say this as a former two pack a day addict.)</p> <p><strong>Kate Caddey</strong> - Stay as fit as you can. Walk, do the stretch, balance and dance offerings. Travel the slightly harder way with ups and downs included. Stay curious about people you meet and about everything in general. Never stop learning.</p> <p><strong>Marie Jones</strong> - Keep laughing.</p> <p><strong>Gloria Hickey</strong> - Keep active, but wish I had been told to have my B12 added to yearly blood work too. </p> <p><strong>Peter Connolly</strong> - Best advice I got was "Whatever you do, go out with a bang. There is absolutely no point in lying in bed in a hospital, dying of nothing!"</p> <p><strong>Terry Dolman</strong> - Enjoy being happy. It takes more energy to be grumpy than smile. Plus, a good Friend in Vietnam now said "don't carry the past plus a drink of whisky a day." </p> <p><strong>Heather Dixon</strong> - Keep busy.</p> <p><strong>Lydia Poli </strong>- Enjoy the ride while you can!</p> <p><strong>Marlene Cochrane</strong> - Don't stop moving.

Readers response: What advice would you give someone visiting Australia?

<p>We asked our readers what advice they would give to someone travelling to Australia, including where tourists need to see and what hidden gems cannot be missed. Here's what they said. </p> <p><strong>Peggy Rice</strong> - Respect our rules, the outback needs to be researched, swim between flags, don't swim with crocodiles. It's the best country in the world, let's keep it that way. Also do yourself a favour and put Tasmania on your list of beauty.</p> <p><strong>Kay L Bayly</strong> - Number 1 advice! Check distances between desired destinations. It is a much bigger country than most people understand.</p> <p><strong>Michael Pender</strong> - Bring a sense of humour.</p> <p><strong>Toni Stewart</strong> - You will need a year at least to see all the different areas from desert, scrub, rainforest, cities, beaches, country side fabulous little towns and lots of festivals.</p> <p><strong>Maureen Prince</strong> - We don’t have Kangaroos running the streets. Koalas are not in everybody's back yard trees. Whilst we do have snakes you’d be very unfortunate if you were to come across a venomous one. We don’t all go around saying “Good day mate”. Our scenery is incredible. Our food is superb and, best of all, we have good friends who do say “Good day mate”.</p> <p><strong>Tina Shaw</strong> - Leave preconceptions at customs. See who we are and you'll have a fantastic time.</p> <p><strong>Dianne Savage</strong> - Put Tasmania on your must do list.</p> <p><strong>Margaret Higgs</strong> - Use sunscreen, wear a hat, drink lots of fluids.</p> <p><strong>Cheryl Anne</strong> - Don't assume you can cover the whole country in 6 weeks.</p> <p><strong>Sarah Hayse-Gregson</strong> - Obey the beach culture. The flags, lifesavers are there for a reason. If a sign says, “beach closed” there’s no one to assist you if you get into difficulty. Our lifesavers are volunteers, don’t forget that. They give up their free time to monitor the beaches and are highly trained. Never turn your back to the sea.</p> <p><strong>Ann Lusby</strong> - Watch out for drop bears.</p> <p><em>Image credits: Shutterstock </em></p>

Hospice nurse shares what happens to the body after death

<p dir="ltr">A hospice nurse has revealed the reality of what happens to our bodies in the minutes, hours and days after we die. </p> <p dir="ltr">In her efforts to break down the taboo around conversations about death, Julie McFadden, a hospice nurse from the US, posts candid videos about death and dying to help us be more informed and prepared. </p> <p dir="ltr">In Julie’s latest video, she explains exactly what happens to the human body in the moments, hours and days after someone dies. </p> <p dir="ltr">Nurse Julie said that in the immediate moments after death, the body completely relaxes, beginning the first stage of decomposition, called hypostasis.</p> <p dir="ltr">“All of the things in your body that are holding fluids in, relaxes. That's why death can be messy sometimes.”</p> <p dir="ltr">She clarified that because of how relaxed the body becomes, those who have just died may urinate, have bowel movements or experience bodily fluids coming out of their nose, mouth, ears or eyes. </p> <p dir="ltr">Nurse Julie added, “I like to talk about it so people aren't surprised if that happens - very normal and to be expected sometimes.”</p> <p dir="ltr">This is also when the stage of decomposition called autolysis, or “the self-digestion” stage, occurs and enzymes begin to break down oxygen-deprived tissue, also causing the body temperature to drop. </p> <p dir="ltr">As the body settles in the hours after death, Nurse Julie said the blood will begin to pool downward toward the ground.</p> <p dir="ltr">She said, “If you let someone lie there for long enough - which we do sometimes; you don't have to hurry up and make sure your loved one leaves the house - if you turn them you will notice usually the back of their legs the whole backside of them will look purple or darker that's because all their blood is pulling down.”</p> <p dir="ltr">“Gravity is pulling it down. So they will eventually get a darker colour tone of skin on their backside.”</p> <p dir="ltr">One to two hours after death is also when rigor mortis - or the stiffening of a body’s muscles - sets in and continues for about the next 24 hours</p> <p dir="ltr">Nurse Julie said, “I have seen people become very stiff almost immediately - like a few minutes - after death and other people, their body takes longer.”</p> <p dir="ltr">Additionally, about 12 hours after death, the body will feel cool to the touch. </p> <p dir="ltr">About a day to a day and a half after a person dies, rigor mortis subsides and the body will begin to loosen again, as Nurse Julie said the body's tissues relax and cause the stiffness to break down.</p> <p dir="ltr">By this time, the body is usually in the mortuary, which will prepare the body in whichever way the family has requested, whether it is for burial or cremation. </p> <p dir="ltr">She added, “In a world where people didn't have access to a mortuary or a healthcare system and they just died naturally, our bodies are built to, after death, decompose.”</p> <p dir="ltr"><em>Image credits: Shutterstock / Instagram / YouTube</em></p>

What’s the difference between liquid and powder laundry detergent? It’s not just the obvious

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>When shopping for a laundry detergent, the array of choices is baffling. All of the products will likely get your laundry somewhat cleaner. But what gets the best outcome for your clothes and your budget?</p> <p>Do you want whiter whites? Do you need enzymes? And what’s the difference between a powder and liquid detergent?</p> <p>As is often the case, knowing more about the chemistry involved will help you answer those questions.</p> <h2>What is a detergent?</h2> <p>The active ingredients in both laundry powders and liquids are “surfactants”, also known as detergents (hence the product name). These are typically charged or “ionic” molecules that have two distinct parts to their structure. One part interacts well with water and the other interacts with oils.</p> <p>This useful property allows surfactants to lift grease and grime from fabrics and suspend it in the water. Surfactants can also form bubbles.</p> <p>Metal salts dissolved in your water can limit the performance of the surfactants. So-called hard water contains lots of dissolved calcium and magnesium salts which can readily form soap scum.</p> <p>Modern laundry detergents therefore contain phosphates, water softeners and other metal “sequestrants” to stop the formation of soap scum. Phosphates can cause algal blooms in fresh water environments. This is why modern detergent formulations <a href="https://accord.asn.au/sustainability/phosphorus-standard/">contain smaller amounts of phosphates</a>.</p> <p>Many products also contain optical brighteners. These chemicals absorb ultraviolet light and release blue light, which provides the “whiter white” or “brighter colour” phenomenon.</p> <p>Laundry detergents typically contain fragrances. These aren’t essential to the chemistry of cleaning, but give the impression the clothes are fresh.</p> <p>Lastly, some laundry detergents contain enzymes – more on those later.</p> <h2>What’s in laundry powder?</h2> <p>While detergents and ingredients to avoid soap scum are the most important components, they aren’t the most abundant. The main ingredients in powders are salts (like sodium sulfate) that add bulk and stop the powder from clumping.</p> <p>Another common salt added to laundry powders is sodium carbonate, also known as washing soda. Washing soda (a chemical cousin of <a href="https://theconversation.com/vinegar-and-baking-soda-a-cleaning-hack-or-just-a-bunch-of-fizz-225177">baking soda</a>) helps to chemically modify grease and grime so they dissolve in water.</p> <p>Laundry powders also frequently contain oxidising agents like sodium percarbonate. This is a stable combination of washing soda and hydrogen peroxide. An additive known as tetraacetylethylenediamine activates the percarbonate to give a mild bleaching effect.</p> <p>Chemically, powders have an advantage – their components can be formulated and mixed but kept separate in a solid form. (You can usually see different types of granules in your laundry powder.)</p> <h2>What’s in laundry liquid?</h2> <p>The main ingredient of laundry liquid is water. The remaining ingredients have to be carefully considered. They must be stable in the bottle and then work together in the wash.</p> <p>These include similar ingredients to the powders, such as alkaline salts, metal sequestrants, water softeners and surfactants.</p> <p>The surfactants in liquid products are often listed as “ionic” (charged) and “non-ionic” (non-charged). Non-ionic surfactants can be liquid by default, which makes them inappropriate for powdered formulations. Non-ionic surfactants are good at suspending oils in water and don’t form soap scum.</p> <p>Liquid detergents also contain preservatives to prevent the growth of microbes spoiling the mixture.</p> <p>There are also microbial implications for inside the washing machine. Liquid products can’t contain the peroxides (mild bleaching agents) found in powdered products. Peroxides kill microbes. The absence of peroxides in liquid detergents makes it more likely for <a href="https://www.mdpi.com/1420-3049/27/1/195#B15-molecules-27-00195">mould biofilms to form</a> in the machine and for bacteria to be transferred between items of clothing.</p> <p>As an alternative to peroxides, liquids will typically contain only optical brighteners.</p> <p>Liquids do have one advantage over powders – they can be added directly to stains prior to placing the item in the wash.</p> <p>A recent “convenience” version of liquid formulas are highly concentrated detergent pods. Colourful and bearing a resemblance to sweet treats, these products have been found to be <a href="https://poisoncenters.org/track/laundry-detergent-packets">dangerous to young children and people with cognitive impairment</a>.</p> <p>Pods also remove the option to add less detergent if you’re running a smaller load or just want to use less detergent in general.</p> <h2>So, what about enzymes?</h2> <p>Enzymes are naturally evolved proteins included in laundry products to remove specific stains. Chemically, they are catalysts – things that speed up chemical reactions.</p> <p>Enzymes are named for the molecules they work on, followed by the ending “-ase”. For example, lipase breaks down fats (lipids), protease breaks down protein, while amylase and mannanase break down starches and sugars.</p> <p>These enzymes are derived from organisms found in cool climate regions, which helps them function at the low temperature of washing water.</p> <p>Running an excessively hot wash cycle can damage or denature the enzyme structure, stopping them from assisting in your wash. Think of an egg white <a href="https://theconversation.com/how-to-make-the-perfect-pavlova-according-to-chemistry-experts-196485">changing from translucent to white while cooked</a> – that’s protein denaturing.</p> <p>If your detergent contains enzymes, the washing temperature should be neither too hot nor too cold. As a guide, temperatures of 15–20°C are used in <a href="https://environment.ec.europa.eu/document/download/557d8ab5-4e75-41a4-a901-1548be7f685d_en">standard laundry tests</a>.</p> <h2>Is powder or liquid better?</h2> <p>We make consumer choices guided by performance, psychology, cost, scent, environmental considerations and convenience.</p> <p>It’s worth experimenting with different products to find what works best for you and fits your needs, household budget and environmental considerations, such as having <a href="https://theconversation.com/curious-kids-why-can-some-plastics-be-recycled-but-others-cant-229270">recyclable packaging</a>.</p> <p>Personally, I wash at 20°C with half the recommended dose of a pleasant-smelling laundry powder, packaged in recyclable cardboard, and containing a wide range of enzymes and an activated peroxide source.</p> <p>Knowing a little chemistry can go a long way to getting your clothes clean.</p> <p>However, laundry detergent manufacturers don’t always disclose the full list of ingredients on their product packaging.</p> <p>If you want more information on what’s in your product, you have to look at the product website. You can also dig a little deeper by reading documents called <a href="https://theconversation.com/a-new-tiktok-trend-has-people-drinking-toxic-borax-an-expert-explains-the-risks-and-how-to-read-product-labels-210278">safety data sheets</a> (SDS).

"What did we do?": Bride shares heartbroken reaction to empty wedding

<p>A bride has recalled the devastating moment she made a grand entrance to her wedding, only to discover almost no guests showed up. </p> <p>Kalina Marie took to TikTok to share the gut-wrenching video of the moment her and her new husband Shane stepped inside the lavishly decorated hall with their son, as they tried to come to terms with the fact that only a handful of people showed to celebrate with them. </p> <p>“This is our entrance to our Masquerade ball,” Ms Marie, who is from Oregon in the US, wrote in the caption of her clip, which has since amassed over seven million views. </p> <p>“The Masquerade ball that I have talked EXCESSIVELY about for the last 10 months. The same ball that I not only digitally invited over 75 people to. But ALSO spent money to send 25 beautiful invitations out to."</p> <p>“FIVE PEOPLE SHOWED UP!!!!!!! Like, are you kidding me!?!? As you see in the video, we enter the venue. And no one is there. The invite said 1pm. My mum messaged me at 1:15pm that no one was there. My husband and I finally showed up at 2 o’clock, to five people, in a venue planned for 40.”</p> <div class="embed" style="font-size: 16px; box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; outline: currentcolor !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; border-style: none; vertical-align: baseline; width: 600px; max-width: 100%; outline: currentcolor !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7433899067664551198&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40kalina_marie_23%2Fvideo%2F7433899067664551198&amp;image=https%3A%2F%2Fp16-pu-sign-useast8.tiktokcdn-us.com%2Fobj%2Ftos-useast8-p-0068-tx2%2F7f29587f56a44788903eea92cd974c62_1730839526%3Flk3s%3Db59d6b55%26x-expires%3D1731499200%26x-signature%3DbUQfTW%252F8BrelG0Dy5rCNSzBBbiQ%253D%26shp%3Db59d6b55%26shcp%3D-&amp;key=5b465a7e134d4f09b4e6901220de11f0&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> <p>She said she “dreamt” that she would walk into a bunch of people “hooting and hollering” for them, but instead ended up having to “hold herself together” because she had “no idea” how to deal with her venue being almost completely empty.</p> <p>“All the wasted food and drinks,” Ms Marie continued. “All the empty tables and chairs. Every moment of my reception changed to adapt.”</p> <p>“It just makes me think, like, why? What did we do? Am I that bad of a person? What did my husband ever do to deserve any of this?” she questioned. “Why couldn’t we matter enough for people to show up?”</p> <p>She revealed that it makes her “sick” that she still has “friends” who haven’t even messaged her to congratulate her or tell her why they didn’t come, adding, “I honestly can’t wrap my head around this yet.”</p> <p>The heart-breaking video quickly wrapped up millions of views and comments, with many empathising with the new bride, with one person writing, "This hurts my heart for you."</p> <p>Thousands of others tried to lighten the mood, praising Ms Marie for how beautiful she looked and vowing to attend a do-over wedding.</p> <p>“NAH, RE-DO THIS. WE ALL SHOWING UP,” read a top comment, while another wrote, “Let’s do it over. This time invite me and the rest of us. We’ll show up and out. I love you beautiful and congratulations!!” </p> <p><em>Image credits: TikTok</em></p>

Matcha is having a moment. What are the health benefits of this green tea drink?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Matcha has experienced a surge in popularity in recent months, leading to reports of <a href="https://www.smh.com.au/goodfood/sydney-eating-out/global-matcha-shortage-hits-australia-as-skyrocketing-popularity-rivals-coffee-20241101-p5kn6v.html">global shortages</a> and price increases.</p> <p>If you haven’t been caught up in the craze, matcha is a powdered version of green tea. On a cafe menu you might see a hot or iced matcha latte, or even a matcha-flavoured cake or pastry. A quick google brings up <a href="https://www.foodandwine.com/tea/matcha-tea/matcha-recipes">countless recipes</a> incorporating matcha, both sweet and savoury.</p> <p>Retailers and cafe owners <a href="https://www.smh.com.au/goodfood/sydney-eating-out/global-matcha-shortage-hits-australia-as-skyrocketing-popularity-rivals-coffee-20241101-p5kn6v.html">have suggested</a> the main reasons for matcha’s popularity include its “instagrammable” looks and its purported health benefits.</p> <p>But what are the health benefits of matcha? Here’s what the evidence says.</p> <h2>First, what is matcha?</h2> <p><a href="https://www.mdpi.com/1420-3049/26/1/85">Matcha</a> is a finely ground powder of green tea leaves, which come from the plant <em>Camellia sinensis</em>. This is the same plant used to make green and black tea. However, the <a href="https://naokimatcha.com/blogs/articles/how-matcha-is-made-in-japan">production process</a> differentiates matcha from green and black tea.</p> <p>For matcha, the tea plant is grown in shade. Once the leaves are harvested, they’re steamed and dried and the stems are removed. Then the leaves are carefully ground at controlled temperatures to form the powder.</p> <p>The <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6571865/">production process</a> for green tea is simpler. The leaves are picked from the unshaded plants, heated and then dried. We then steep the dried leaves in hot water to get tea (whereas with matcha the whole leaf is consumed).</p> <p>With black tea, after the leaves are picked they’re exposed to air, which leads to oxidation. This makes the leaves black and gives the tea a different flavour.</p> <h2>A source of phytonutrients</h2> <p>Phytonutrients are <a href="https://theconversation.com/phytonutrients-can-boost-your-health-here-are-4-and-where-to-find-them-including-in-your-next-cup-of-coffee-132100">chemical compounds found in plants</a> which have a range of benefits for human health. Matcha contains several.</p> <p>Chlorophyll gives plants such as <em>Camellia sinensis</em> their green colour. There’s some evidence chlorophyll may have <a href="https://www.mdpi.com/2223-7747/12/7/1533">health benefits</a> – including anti-inflammatory, anti-cancer and anti-obesity effects – due to its antioxidant properties. Antioxidants neutralise free radicals, which are unstable molecules that harm our cells.</p> <p>Theanine has been shown to <a href="https://www.mdpi.com/2504-3900/91/1/32">improve sleep</a> and <a href="https://link.springer.com/article/10.1007/s11130-019-00771-5?crsi=662497574&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct">reduce stress and anxiety</a>. The only <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/theanine">other known</a> dietary source of theanine is mushrooms.</p> <p>Caffeine is a phytonutrient we know well. Aside from increasing alertness, caffeine has also demonstrated <a href="https://www.tandfonline.com/doi/full/10.1080/10408398.2022.2074362?casa_token=ADALIs6M3iAAAAAA%3AXpY35se0zLddAEIbZAaeCcDaNWm94s2WJaDHfXDRvVZgYq_xTxsCFuvtrtNXMXAL9uNIvLlYzO30aA#abstract">antioxidant effects</a> and some protection against a range of chronic and neurodegenerative diseases. However, too much caffeine can have negative side effects.</p> <p>Interestingly, shading the plants while growing appears to <a href="https://scijournals.onlinelibrary.wiley.com/doi/pdfdirect/10.1002/jsfa.9112?casa_token=KxVD9i9p4BsAAAAA:OwGTauXFHAndyJkam8WuXrmGQ2k1kaSRu5pOqJOrhSyRSeWkDwdrI23qaD5WVH1HGqZLFdsjP9ZTvolw">change the nutritional composition</a> of the leaf and may lead to higher levels of these phytonutrients in matcha compared to green tea.</p> <p>Another compound worth mentioning is called catechins, of which there are several different types. Matcha powder similarly has <a href="https://theconversation.com/matcha-tea-what-the-current-evidence-says-about-its-health-benefits-202782">more catechins</a> than green tea. They are strong antioxidants, which <a href="https://link.springer.com/article/10.1186/s41702-020-0057-8">have been shown</a> to have protective effects against bacteria, viruses, allergies, inflammation and cancer. Catechins <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/catechin#:%7E:text=Catechin%20is%20naturally%20present%20in,containing%20many%20catechins%20%5B130%2C131%5D.">are also found</a> in apples, blueberries and strawberries.</p> <h2>What are the actual health benefits?</h2> <p>So we know matcha contains a variety of phytonutrients, but does this translate to noticeable health benefits?</p> <p>A review published in 2023 identified only <a href="https://www.sciencedirect.com/science/article/pii/S2665927122002180">five experimental studies</a> that have given matcha to people. These studies gave participants about 2–4g of matcha per day (equivalent to 1–2 teaspoons of matcha powder), compared to a placebo, as either a capsule, in tea or in foods. Matcha decreased stress and anxiety, and improved memory and cognitive function. There was no effect on mood.</p> <p>A <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0309287">more recent study</a> showed 2g of matcha in older people aged 60 to 85 improved sleep quality. However, in <a href="https://www.mdpi.com/2072-6643/16/17/2907">younger people</a> aged 27 to 64 in another study, matcha had little effect on sleep.</p> <p>A <a href="https://link.springer.com/article/10.1007/s11130-022-00998-9">study in people with obesity</a> found no difference in the weight loss observed between the matcha group and the control group. This study did not randomise participants, and people knew which group they had been placed in.</p> <p>It could be hypothesised that given you consume all of the leaf, and given levels of some phytonutrients may be higher due to the growing conditions, matcha may have more nutritional benefits than green tea. But to my knowledge there has been no direct comparison of health outcomes from green tea compared to matcha.</p> <h2>There’s lots of evidence for green tea</h2> <p>While to date a limited number of studies have looked at matcha, and none compared matcha and green tea, there’s quite a bit of research on the health benefits of drinking green tea.</p> <p>A <a href="https://www.sciencedirect.com/science/article/pii/S0944711317300867?casa_token=dpbAEQQ7Is4AAAAA:U6aggqZM_G0KJ8hkhx0TGSvQywr4utlgKzwUnUj9x5t9eWd-FKENjbTvUv6s4TBTaPYrob-qQkk">systematic review of 21 studies</a> on green tea has shown similar benefits to matcha for improvements in memory, plus evidence for mood improvement.</p> <p>There’s also evidence green tea provides other health benefits. Systematic reviews have shown green tea leads to <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ptr.6697?casa_token=1eAbmeGillYAAAAA%3ABNGBB6EuRFXIDWHgsa7E798wfC0MQK2r3yOmAlFzR2sxyD9Xt837VoCel0l6Tsh3RRO19t-YUm1GqO7Y">weight loss in people with obesity</a>, lower levels of <a href="https://link.springer.com/article/10.1186/s12937-020-00557-5">certain types of cholesterol</a>, and <a href="https://journals.lww.com/md-journal/fulltext/2020/02070/Effect_of_green_tea_supplementation_on_blood.36.aspx/1000">reduced blood pressure</a>. Green tea may also <a href="https://www.nature.com/articles/s41430-020-00710-7">lower the risk of certain types of cancer</a>.</p> <p>So, if you can’t get your hands on matcha at the moment, drinking green tea may be a good way to get your caffeine hit.</p> <p>Although the evidence on green tea provides us with some hints about the health benefits of matcha, we can’t be certain they would be the same. Nonetheless, if your local coffee shop has a good supply of matcha, there’s nothing to suggest you shouldn’t keep enjoying matcha drinks.</p> <p>However, it may be best to leave the matcha croissant or cronut for special occasions. When matcha is added to foods with high levels of added sugar, salt and saturated fat, any health benefits that could be attributed to the matcha may be negated.<!-- Below is The Conversation's page counter tag.

Our <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">new research</a> compared three weight-loss methods, to see if one delivered more weight loss than the others:</p> <ul> <li>altering calorie distribution – eating more calories earlier rather than later in the day</li> <li>eating fewer meals</li> <li>intermittent fasting.</li> </ul> <p>We analysed data from 29 clinical trials involving almost 2,500 people.</p> <p>We found that over 12 weeks or more, the three methods resulted in similar weight loss: 1.4–1.8kg.</p> <p>So if you do want to lose weight, choose a method that works best for you and your lifestyle.</p> <h2>Eating earlier in the day</h2> <p>When our metabolism <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/metabolic-syndrome">isn’t functioning properly</a>, our body can’t respond to the hormone insulin properly. This can lead to weight gain, fatigue and can increase the risk of a number of chronic diseases such as diabetes.</p> <p>Eating later in the day – with a <a href="https://pubmed.ncbi.nlm.nih.gov/23512957/">heavy dinner</a> and late-night snacking – seems to lead to <a href="https://pubmed.ncbi.nlm.nih.gov/33172509/">worse metabolic function</a>. This means the body becomes less efficient at converting food into energy, managing blood sugar and regulating fat storage.</p> <p>In contrast, consuming calories <a href="https://pubmed.ncbi.nlm.nih.gov/31151228/">earlier</a> in the day appears to <a href="https://pubmed.ncbi.nlm.nih.gov/29754952/">improve</a> metabolic function.</p> <p>However, this might not be the case for everyone. Some people naturally have an evening “chronotype”, meaning they wake up and stay up later.</p> <p>People with this chronotype appear to have <a href="https://pubmed.ncbi.nlm.nih.gov/36803075/">less success losing weight</a>, no matter the method. This is due to a combination of factors including genes, an increased likelihood to have a poorer diet overall and higher levels of hunger hormones.</p> <h2>Eating fewer meals</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/30700403/">Skipping breakfast</a> is common, but does it hinder weight loss? Or is a <a href="https://pubmed.ncbi.nlm.nih.gov/28967343/">larger breakfast and smaller dinner</a> ideal?</p> <p>While <a href="https://pubmed.ncbi.nlm.nih.gov/28137935/">frequent meals</a> may reduce disease risk, recent studies suggest that compared to eating one to two meals a day, eating six times a day might increase <a href="https://pubmed.ncbi.nlm.nih.gov/32437566/">weight loss success</a>.</p> <p>However, this doesn’t reflect the broader research, which tends to show consuming <a href="https://pubmed.ncbi.nlm.nih.gov/33485709/">fewer meals</a> can lead to greater weight loss. <a href="https://pubmed.ncbi.nlm.nih.gov/39485353/">Our research</a> suggests three meals a day is better than six. The easiest way to do this is by cutting out snacks and keeping breakfast, lunch and dinner.</p> <p>Most studies compare three versus six meals, with limited evidence on whether <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7490164/">two meals is better than three</a>.</p> <p>However, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">front-loading your calories</a> (consuming most of your calories between breakfast and lunch) appears to be better for weight loss and may also help <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9605877/">reduce hunger</a> across the day. But more studies with a longer duration are needed.</p> <h2>Fasting, or time-restricted eating</h2> <p>Many of us eat over a period of more than <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">14 hours a day</a>.</p> <p>Eating late at night <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">can throw off</a> your body’s natural rhythm and alter how your organs function. Over time, this can increase your risk of type 2 diabetes and other chronic diseases, particularly among <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8617838/">shift workers</a>.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/35194176/">Time-restricted eating</a>, a form of intermittent fasting, means eating all your calories within a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">six- to ten-hour window</a> during the day when you’re most active. It’s not about changing what or how much you eat, but <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">when you eat it</a>.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">Animal studies</a> suggest time-restricted eating can lead to weight loss and improved metabolism. But the evidence in humans is still limited, especially about the long-term benefits.</p> <p>It’s also unclear if the benefits of time-restricted eating are due to the timing itself or because people are eating less overall. When we looked at studies where participants ate freely (with no intentional calorie limits) but followed an eight-hour daily eating window, they naturally consumed about 200 fewer calories per day.</p> <h2>What will work for you?</h2> <p>In the past, clinicians have thought about weight loss and avoiding weight gain as a simile equation of calories in and out. But factors such as how we distribute our calories across the day, how often we eat and whether we eat late at night may also impact our metabolism, weight and health.</p> <p>There are no easy ways to lose weight. So choose a method, or combination of methods, that suits you best. You might consider</p> <ul> <li>aiming to eat in an eight-hour window</li> <li>consuming your calories earlier, by focusing on breakfast and lunch</li> <li>opting for three meals a day, instead of six.</li> </ul> <p>The <a href="https://link.springer.com/article/10.1007/s13679-024-00555-2">average adult gains 0.4 to 0.7 kg per year</a>. Improving the quality of your diet is important to prevent this weight gain and the strategies above might also help.</p> <p>Finally, there’s still a lot we don’t know about these eating patterns. Many existing studies are short-term, with small sample sizes and varied methods, making it hard to make direct comparisons.</p> <p>More research is underway, including well-controlled trials with larger samples, diverse populations and consistent methods. So hopefully future research will help us better understand how altering our eating patterns can result in better health.<!-- Below is The Conversation's page counter tag.

Readers response: What piece of travel memorabilia brings back the best memories for you?

<p>When we travel, many of us love to pick up a souvenir to remind us of our holidays and the destinations we loved. </p> <p>We asked our readers what piece of travel memorabilia brings back the best memories, and the response was overwhelming. Here's what they said.</p> <p><strong>Jan Hall</strong> - Christmas Decorations! Then when I put my tree up it’s like a trip down memory lane, first one was 1973 from Singapore our first overseas holiday.</p> <p><strong>Debra Stone</strong> - A letter opener with a Paua shell on the handle. New Zealand wouldn't let us take it in our luggage, so we posted it home to ourselves!</p> <p><strong>Becky Murfet</strong> - In 1984 we went to Europe and I collected match boxes from different countries. Have them in a large glass bowl. Great to look at for memories sake.</p> <p><strong>Caron Castner</strong> - Stines from Germany.</p> <p><strong>Margie Buckingham</strong> - A palm-sided wooden carved elephant from a side trip off my cruise from Singapore to Malaysia &amp; Thailand and back to celebrate my 40th. It sits on my mantelpiece so to deliberately trigger good memories of a younger me.</p> <p><strong>Frank Nieuwenhuis</strong> - 2300 year old oil lamp bought in Israel.</p> <p><strong>Fay Russell</strong> - Turkish tea set. </p> <p><strong>Valma Blake</strong> - Of all the things I've bought on my travels, my favourite is my cat ornament collection that are decorated relative to the country or area I visited.</p> <p><em>Image credits: Shutterstock </em></p>

He intends to be an activist and transformative president. Now Americans and the rest of the world must brace for the global fallout in Ukraine, Russia, China, Israel and Iran.</p> <p>According to the <a href="https://www.bbc.com/news/topics/cj3ergr8209t">latest tabulations</a>, more than 71 million of Trump’s followers stayed loyal to the MAGA movement despite <a href="https://theconversation.com/trump-found-guilty-5-key-aspects-of-the-trial-explained-by-a-law-professor-231236">his criminal convictions and indictments</a>, <a href="https://www.motherjones.com/politics/2024/09/trump-hate-speech-migrants-campaign-rallies-incitement/">hate speech</a> and <a href="https://www.washingtonpost.com/politics/how-fact-checker-tracked-trump-claims/2021/01/23/ad04b69a-5c1d-11eb-a976-bad6431e03e2_story.html">fire hose of lies</a>.</p> <p>Trump won the presidency with the help of blue-collar, middle-class voters in the vital centre of the political spectrum, and in open defiance of the political establishment and most political power brokers.</p> <h2>Weak centre</h2> <p>What does Trump’s comeback mean for his unique brand of nationalist authoritarianism?</p> <p>Trump’s victory shows just how weak and lacklustre the centre has become in comparison to surging extremism. The silent majority that once rallied to support Ronald Reagan’s popular agenda, for example, is now a seemingly amoral majority indifferent to Trump’s felonies and his apocalyptic vision for the country.</p> <p>It’s now clear that the <a href="https://www.nytimes.com/2024/10/23/opinion/election-polls-results-trump-harris.html">undecided centre</a> is smaller than ever. Voters on the left were dismayed about Kamala Harris’s support for Benjamin Netanyahu’s government in Israel. Some planned not to vote or <a href="https://www.forbes.com/sites/stephenpastis/2024/11/04/will-third-party-candidates-be-2024-spoilers-heres-the-latest-data-as-trump-harris-race-nearly-tied/">to vote for third-party</a> candidates.</p> <p>What’s more, Republicans have been courting working class and racialized voters for years, and their messaging is paying off. Chipping away small numbers of <a href="https://www.pewresearch.org/short-reads/2024/01/10/key-facts-about-black-eligible-voters-in-2024/">Black</a> and <a href="https://www.pewresearch.org/short-reads/2024/07/19/how-latino-voters-view-the-2024-presidential-election/">Latino</a> voters is adding up to <a href="https://thehill.com/homenews/campaign/4975849-trump-harris-2024-presidential-run/?ipid=promo-link-block1">real gains</a>.</p> <h2>‘Make extremism great again’</h2> <p>The Republican machine has grasped an essential truth: parties must redefine their centre of gravity with the shifting of the <a href="https://www.mackinac.org/OvertonWindow">Overton window</a> of political acceptability, which holds that the centre is not fixed forever; it is simply a gauge of the new extremes.</p> <p>After a decade of the upheaval Trump has fuelled, mainstreaming extremism has become a proven formula for winning elections. The most basic question emphasized by the Trump-Harris showdown was: Can <a href="https://www.thenation.com/article/politics/myth-cheney-democrats-harris-walz-campaign/">cautious centrism</a> defeat <a href="https://www.iiss.org/online-analysis/survival-online/2021/01/trump-politics-of-paranoia/">paranoid populism</a>?</p> <p>In America in 2024, it could not.</p> <p>After 1945, the centre referred to the vast number of voters who rejected <a href="https://www.latimes.com/opinion/story/2024-09-13/on-freedom-timothy-snyder-erasing-history-jason-stanley-book-review">communism and fascism</a> while embracing the welfare state and full-employment capitalism.</p> <figure class="align-left zoomable"></figure> <p>This middle “<a href="https://www.theguardian.com/politics/2003/feb/10/labour.uk1">or third way</a>” — sought by politicians from Tony Blair to Barack Obama — won repeated elections. But today, the centre has been eclipsed by loyalty to a charismatic leader.</p> <p>When the extremes cease to be red lines, reasonable parties can only intermittently eke out a win. That means extremist movements grow ever stronger. What will happen in four years is anyone’s guess. But even after Trump is gone, he will live on atop the conservative pantheon, having risen to even greater esteem among his supporters than Reagan or <a href="https://www.politico.com/magazine/story/2014/10/barry-goldwater-lasting-legacy-112210/">Barry Goldwater</a>, the Republican senator who became a conservative standard-bearer for a generation.</p> <h2>Negative voting</h2> <p>The American election turned on negative voting. The only real question was whose fear would carry the day?</p> <p>Democrats feared the loss of <a href="https://www.brookings.edu/articles/freedom-harriss-message-to-america/">reproductive freedoms</a> for women. Republicans feared immigration conspiracy theories such as “<a href="https://www.npr.org/2022/05/17/1099223012/how-the-replacement-theory-went-mainstream-on-the-political-right">the great replacement</a>” theory.</p> <p>Republicans made border security a successful culture war issue, and it will unquestionably loom even larger in future elections. Gallup has shown that 55 per cent of Americans now want immigration levels <a href="https://news.gallup.com/poll/647123/sharply-americans-curb-immigration.aspx">drastically reduced</a>, a significant rise from 41 per cent just last year.</p> <p>The United States is not alone. What began as anger over Syrian refugees in Germany has metastasized into an enormous <a href="https://www.fosterglobal.com/blog/its-not-just-the-u-s-europes-growing-anti-immigration-backlash/">anti-immigrant backlash across Europe</a>. Anti-immigration sentiment is on the rise <a href="https://immigration.ca/canada-rated-best-country-in-world-for-welcoming-immigrants/">in Canada too despite it being one of the most welcoming nations in terms of immigration</a>.</p> <h2>The rise of anti-immigration sentiment</h2> <p>Future Republican contenders will almost certainly be avowed opponents of immigration given Trump’s stunning comeback. He leveraged the issue at a time when immigrants and border security have become powerful symbols of the enormous changes brought about by globalization.</p> <p>Zygmunt Bauman, the late eminent Polish sociologist, has described the technological advancement that defines global capitalism as “<a href="https://www.theoryculturesociety.org/blog/review-ali-rattansi-bauman-and-contemporary-sociology">liquid modernity</a>.”</p> <p>He argues that constant change <a href="https://openknowledge.worldbank.org/handle/10986/40672">rewards the wealthy and the hyper-mobile</a>. The blue-collar middle class is not worse off in absolute terms, but they’re <a href="https://reviewcanada.ca/magazine/2023/01/the-shill-of-the-people/">falling behind</a> as the billionaire class surges ahead and governments fail to protect the traditional institutions of the welfare state.</p> <p>For Trump voters, the “<a href="https://www.nbcnews.com/meet-the-press/video/trump-doubles-down-on-enemy-within-rhetoric-in-final-campaign-push-222300229921">enemy within</a>” was the most potent narrative for the MAGA coalition. Xenophobia was on <a href="https://www.nytimes.com/2024/10/28/opinion/trump-rally-msg-racism.html">full display</a> during the closing days of the campaign when a comedian at Trump’s Madison Square Garden rally referred to Puerto Rico as an “<a href="https://www.bbc.com/news/articles/cy9jj2g75q4o">island of garbage</a>.”</p> <p>The full force of liquid modernity continues to degrade the institutions of advanced societies and to reward rule-breakers. It’s not hyperbole to suggest this election could transform both America and the post-war <a href="https://www.foreignaffairs.com/united-states/how-trump-will-change-world">liberal international order</a>.</p> <h2>A dark MAGA future</h2> <p>One primary takeaway from this election is that an even darker, more apocalyptic form of the MAGA movement has taken hold. At a recent rally, Elon Musk, the world’s richest man, <a href="https://www.vanityfair.com/news/story/elon-musk-donald-trump-dark-maga-twitter">joined Trump on stage in a black MAGA cap, declaring</a>: “I’m not just MAGA, I’m dark MAGA.”</p> <p>In Trump’s warped view, an electoral loss would have been proof of cheating, but a win is a triumph of the will. In America today, conspiracy theories seemingly attract votes.</p> <p>It’s hard to underestimate the impact of Trump’s toxicity on American civic life. With his new mandate, Trump has a green light to implement most, if not all, of his most extreme policies, from tariffs to cementing an absolutist approach to presidential power.</p> <p>Trump has already promised to prosecute “<a href="https://www.cnn.com/2024/09/08/politics/trump-threatens-prosecution-2024-election-officials/index.html">to the fullest extent of the law</a>” his political enemies. He has threatened to use American troops to round up 15 million undocumented immigrants. It is his stated intent to exercise enormous presidential privilege by pardoning the “patriots” who stormed the capital in January 2021 “<a href="https://www.msnbc.com/deadline-white-house/deadline-legal-blog/trump-jan-6-pardons-day-one-2024-election-rcna170194">on Day One</a>.”</p> <p>It is far from certain that the American constitutional order will survive intact.<!-- Below is The Conversation's page counter tag.

Australian beachgoers are told to always ‘swim between the flags’ – but what if there aren’t any?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/rob-brander-111027">Rob Brander</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>This summer, millions of people will flock to Australia’s beaches – and tragically, not all will survive. Last summer, 54 people <a href="https://issuu.com/surflifesavingaustralia/docs/slsa_summerdrowningreport_2022.23">drowned</a> along the Australian coast. This included 28 people in New South Wales – the highest number in the state’s recorded history.</p> <p>About 80% of the drownings occurred at beaches and almost half were due to people caught in offshore flowing <a href="https://www.sciencedirect.com/science/article/pii/S0012825216303117">rip currents</a>.</p> <p>Crucially, all of these drownings occurred in locations not patrolled by professional lifeguards or volunteer surf lifesavers. That is a stark statistic.</p> <p>The core safety message promoted to beachgoers is to always “swim between the flags” on patrolled beaches. But clearly, unpatrolled beaches represent the major beach safety challenge in Australia – and this must be addressed.</p> <h2>All drownings are preventable</h2> <p>A <a href="https://www.sciencedirect.com/science/article/pii/S1326020023000961">recent study</a> showed coastal drowning rates in Australia did not change between 2004 and 2021. This was despite significant financial investment into coastal safety by all levels of government during this time.</p> <p>And in 2023, the NSW government <a href="https://www.nsw.gov.au/media-releases/splash-for-surf-life-saving-as-patrol-season-begins">announced</a> the biggest ever funding commitment to Surf Life Saving NSW (SLSNSW) – A$23 million over four years.</p> <p>This raises important questions for both beach safety providers and their funding bodies. Are we doing enough to address the issue of drowning on unpatrolled beaches? Why aren’t we seeing a decrease in the number and rate of beach drowning? Is the current approach working? Are we doing enough evaluation?</p> <p>These questions need to be answered because beach drowning, like all types of drowning, is preventable.</p> <h2>The ‘swim between the flags’ message is not enough</h2> <p>The safest place to swim on Australian beaches is between the red and yellow flags, under the supervision of trained lifeguards and surf lifesavers. This is the core safety message promoted to beachgoers, and should always take precedent.</p> <p>But it’s unrealistic to assume beachgoers will always adhere to the message – in part, because the flags and lifeguards aren’t everywhere at all times.</p> <p><a href="https://www.theguardian.com/australia-news/2023/dec/02/ai-rip-detection-technology-australia-beach-safety-drownings#:%7E:text=Fewer%20than%205%25%20of%20Australia%27s,is%20unpatrolled%20or%20temporarily%20unpatrolled.">Less than 5%</a> of Australia’s 11,000 beaches are patrolled, and most of those are patrolled only seasonally. Patrols rarely cover early mornings and evenings when many people choose to swim, and the supervised flagged area may only cover a tiny percentage of the length of the beach.</p> <p>A <a href="https://nhess.copernicus.org/articles/22/909/2022/">recent study</a> documented why beachgoers swim at unpatrolled beaches. The reasons included proximity to their holiday accommodation and because the location is quieter and less crowded than patrolled beaches.</p> <p>So while most Australians know they should swim between the flags, many choose not to, or simply don’t have the option. This can have fatal consequences. Surf Life Saving Australia’s latest National Coastal Safety Report <a href="https://issuu.com/surflifesavingaustralia/docs/ncsr23?fr=xKAE9_zU1NQ">report</a> reported that 75% of the 902 coastal drowning deaths over the previous decade occurred more than 1km from a surf lifesaving service.</p> <h2>Getting it right</h2> <p>There’s an obvious need in Australia for a beach safety campaign that directly addresses safety on unpatrolled beaches. But we have to get it right – and taking an evidence-based approach is crucial.</p> <p>For example, it seems logical to teach beachgoers how to identify dangerous rip currents. But <a href="https://www.sciencedirect.com/science/article/pii/S0278434322000760?casa_token=pYdktxnHyagAAAAA:mBxg-eaXyKJUNDOCJWFSntEcDV7jE6uDEg0bRxugetG7rHelw-_v8zuEXPwUKoGxkL-DNYI">research has shown</a> that people armed with this knowledge might become emboldened to swim at unpatrolled beaches.</p> <p>In 2018, Surf Life Saving Australia launched the “<a href="https://www.youtube.com/watch?v=j47ML57SPyk">Think Line</a>” campaign, which encourages beachgoers to spend a few minutes thinking about beach safety when they arrive at the beach. It’s a simple concept that could become generational over time. But it requires more promotion, more collaboration between beach safety providers, and more research into whether the message is changing beachgoer behaviour in a positive way.</p> <p>Other efforts to improve safety on unpatrolled beaches include investment in technology such as <a href="https://www.surflifesaving.com.au/emergency-response-beacons/#:%7E:text=The%20ERB%20uses%20the%20latest,reassurance%20in%20an%20emergency%20situation.">emergency response beacons</a>. However, to date there’s been little to no evidence-based evaluation of their effectiveness.</p> <p>Research into beach safety is a powerful tool. It provides evidence that can identify which educational approaches are working and which are not. Yet, funding of beach safety research pales in comparison to the amounts invested in untested safety interventions, or upgrades to existing surf club facilities and equipment.</p> <p>It’s globally accepted that lifeguards are the best beach safety intervention. So why aren’t we directing more funding into increasing the presence of local government lifeguard services?</p> <p>This expansion should involve extending lifeguard patrol hours during the summer on patrolled beaches and adding seasonal lifeguards on popular but hazardous unpatrolled beaches.</p> <h2>Staying safe this summer</h2> <p>Preventing drownings on our beaches requires a new approach – and some serious questions about where funding should be best directed. Otherwise, the terrible drowning death toll will continue.</p> <p>In the meantime, you might find yourself wanting to swim at an unpatrolled beach this summer, or to swim early in the morning before lifeguards start duty. To help you understand the hazards and stay safe, UNSW Sydney has developed a new <a href="https://news.unsw.edu.au/en/if-in-doubt--don-t-go-out">educational resource</a>, including a <a href="https://youtu.be/3qXDBvO8mdc">video</a>. They are both worth a look; in fact, they may just save a life.<!-- Below is The Conversation's page counter tag.

What does a good death look like when you’re really old and ready to go?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/naomi-richards-182120">Naomi Richards</a>, <a href="https://theconversation.com/institutions/university-of-glasgow-1269">University of Glasgow</a></em></p> <p><a href="https://www.huffingtonpost.co.uk/entry/hawaii-legalizes-assisted-suicide_us_5ac6c6f5e4b0337ad1e621fb">Hawaii</a> recently joined the growing number of states and countries where doctor-assisted dying is legal. In these jurisdictions, help to die is rarely extended to those who don’t have a terminal illness. Yet, increasingly, very old people, without a terminal illness, who feel that they have lived too long, are arguing that they also have a right to such assistance.</p> <p>Media coverage of <a href="https://www.washingtonpost.com/news/to-your-health/wp/2018/05/09/this-104-year-old-plans-to-die-tomorrow-and-hopes-to-change-views-on-assisted-suicide/?utm_term=.b00a9036f9bc">David Goodall</a>, the 104-year-old Australian scientist who travelled to Switzerland for assisted dying, demonstrates the level of public interest in ethical dilemmas at the <a href="https://www.bmj.com/content/361/bmj.k1891.full">extremities of life</a>. Goodall wanted to die because he no longer enjoyed life. Shortly before his death, he told reporters that he spends most of his day just sitting. “What’s the use of that?” he asked.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0277953615002889?via%3Dihub">Research</a> shows that life can be a constant struggle for the very old, with social connections hard to sustain and health increasingly fragile. <a href="https://www.ncbi.nlm.nih.gov/pubmed/25982088">Studies</a> looking specifically at the motivation for assisted dying among the very old show that many feel a deep sense of loneliness, tiredness, an inability to express their individuality by taking part in activities that are important to them, and a hatred of dependency.</p> <p>Of the jurisdictions where assisted dying is legal, some make suffering the determinant (Canada, for example). Others require a prognosis of six months (California, for example). Mainly, though, the focus is on people who have a terminal illness because it is seen as less of an ethical problem to hasten the death of someone who is already dying than someone who is simply tired of life.</p> <h2>Why give precedence to physical suffering?</h2> <p>Assisted dying for people with psychological or existential reasons for wanting to end their life is unlikely to be supported by doctors because it is not objectively verifiable and also potentially remediable. In the Netherlands, despite the legal power to offer assistance where there is no life-limiting illness, doctors are <a href="https://www.ncbi.nlm.nih.gov/pubmed/25693947">seldom convinced</a> of the unbearable nature of non-physical suffering, and so will rarely administer a lethal dose in such cases.</p> <p>Although doctors may look to a physical diagnosis to give them confidence in their decision to hasten a patient’s death, physical symptoms are often not mentioned by the people they are assisting. Instead, the most common reason given by those who have received help to die is <a href="https://www.nejm.org/doi/full/10.1056/NEJMms1700606">loss of autonomy</a>. Other common reasons are to avoid burdening others and not being able to enjoy one’s life – the exact same reason given by Goodall. This suggests that requests from people with terminal illness, and from those who are just very old and ready to go, are not as different as both the law – and doctors’ interpretation of the law – claim them to be.</p> <h2>Sympathetic coverage</h2> <p>It seems that the general public does not draw a clear distinction either. Most of the media coverage of Goodall’s journey to Switzerland was sympathetic, to the dismay of <a href="http://www.carenotkilling.org.uk/press-releases/centenarians-assisted-suicide/">opponents</a> of assisted dying.</p> <p>Media reports about <a href="https://www.theguardian.com/tv-and-radio/2014/sep/02/mary-berry-great-british-bake-off-centenarian-assisted-dying">ageing celebrities</a> endorsing assisted dying in cases of both terminal illness and very old age, blur the distinction still further.</p> <p>One of the reasons for this categorical confusion is that, at root, this debate is about what a good death looks like, and this doesn’t rely on prognosis; it relies on <a href="https://www.tandfonline.com/doi/full/10.1080/01459740.2016.1255610">personality</a>. And, it’s worth remembering, the personalities of the very old are as diverse as those of the very young.</p> <p>Discussion of assisted suicide often focuses on concerns that some older people may be exposed to coercion by carers or family members. But older people also play another role in this debate. They make up the rank and file <a href="http://www.ep.liu.se/ej/ijal/2012/v7/i1/a01/ijal12v7i1a01.pdf">activists</a> of the global right-to-die movement. In this conflict of rights, protectionist impulses conflict with these older activists’ demands to die on their own terms and at a time of their own choosing.</p> <p>In light of the <a href="https://www.nih.gov/news-events/news-releases/worlds-older-population-grows-dramatically">unprecedented ageing</a> of the world’s population and increasing longevity, it is important to think about what a good death looks like in deep old age. In an era when more jurisdictions are passing laws to permit doctor-assisted dying, the choreographed death of a 104-year-old, who died listening to Ode to Joy after enjoying a last fish supper, starts to look like a socially approved good death.<!-- Below is The Conversation's page counter tag.

Readers response: What’s one thing you wish you had known before retiring?

<p>When it comes time to retire, there are always things we wish we knew first before entering our golden years. </p> <p>We asked our readers what they wish they knew before retiring, and the response was overwhelming. Here's what they said. </p> <p><strong>Margaret Walsh</strong> - As long as you are fit and active, it's great. Just don't get crook or disabled, it sucks.</p> <p><strong>Judi Bradshaw</strong> - I retired 9 times and kept going back to work as I didn't find myself ready to stop work, but finally retired at 73. Took awhile to adjust but now 75 and full time travellers, just loving life.</p> <p><strong>Marcus von Moger</strong> - How good it was going to be.</p> <p><strong>Chris Bailey</strong> - How boring it is, I’d go back to work in a heartbeat if I could.</p> <p><strong>Ellen Fowler</strong> - That the government would keep changing the rules. </p> <p><strong>Michael L Carrigg</strong> - Just how long it takes dealing with government departments that clearly are understaffed, especially in the front line service areas.</p> <p><strong>Jim Burgess</strong> - Finding reasonably priced accommodation.</p> <p><strong>Nicol Kyriakidou</strong> - That it would be so great! Having the whole day to yourself. Taking it easy, meeting friends, going shopping. Doing everything at your leisure.</p> <p><strong>Gaye Johnson</strong> - You never get a day off!!!</p> <p><strong>David Brown</strong> - How good it is. I should have retired 20 years earlier.</p> <p><em>Image credits: Shutterstock </em></p>
