New research proves travelling can slow down the ageing process

<p>It turns out that going on holiday is good for you in more ways than one. </p> <p>According to new research conducted at Edith Cowan University in Western Australia, travelling can actually slow the ageing process both physically and mentally.</p> <p>The study, published in the <a title="Journal of Travel Research" href="https://journals.sagepub.com/doi/10.1177/00472875241269892#:~:text=The%20principle%20of%20entropy%20increase%20provides%20a%20dynamic%20perspective%20to,Silva%20%26%20Annamalai%2C%202008)." target="_blank" rel="noopener">Journal of Travel Research</a>, is believed to be the first-ever that applied the theory of entropy - the general trend of the universe towards death and disorder – to tourism.</p> <p>"Tourism isn't just about leisure and recreation. It could also contribute to people's physical and mental health," ECU PhD candidate Fangli Hu said.</p> <p>"Ageing, as a process, is irreversible. While it can't be stopped, it can be slowed down."</p> <p>According to the research, travelling, exploring new corners of the world and engaging in unique and relaxing activities can stimulate stress responses and elevate metabolic rates, positively influencing metabolic activities and the body's self-organising capabilities.</p> <p>"Leisurely travel activities might help alleviate chronic stress, dampen over-activation of the immune system, and encourage normal functioning of the self-defence system," Fangli added.</p> <p>While some people prefer relaxing holidays, others prefer to stay on their feet and keep active during their travels, enjoying the many well-known benefits of exercise.</p> <p>It can "enhance the body's immune function and self-defence capabilities, bolstering its hardiness to external risks".</p> <p>In response to their study, the experts suggested that "travel therapy could serve as a groundbreaking health intervention."</p> <p>Despite the positive results of the research, experts also warned that travelling can exposed to infectious diseases, accidents, injuries, violence, water and food safety issues, and concerns related to inappropriate tourism engagement, which in turn will have the opposite effect on our health.</p> <p>"Conversely, tourism can involve negative experiences that potentially lead to health problems, paralleling the process of promoting entropy increase," Fangli said.</p> <p><em>Image credits: Shutterstock </em></p>

As the northern hemisphere high season ends, Aotearoa New Zealand is preparing for an influx of visitors ahead of its summer tourism season.</p> <p>And much like those other <a href="https://www.nytimes.com/2024/09/08/world/europe/greece-cruise-ships-tourists-islands.html">tourist hotspots</a>, the government is looking at how to manage the negative effects of tourism on local communities and the environment. This includes tripling the <a href="https://www.theguardian.com/world/article/2024/sep/04/new-zealand-to-nearly-triple-tourist-tax-for-international-visitors">international tourist tax</a> from NZ$35 to $100.</p> <p>The aim of the increase is to <a href="https://www.theguardian.com/world/2022/aug/11/new-zealand-tourism-minister-makes-pitch-to-the-rich-as-he-spurns-10-a-day-travellers">attract tourists</a> who are more mindful of their impact and willing to contribute to its mitigation, while also <a href="https://theconversation.com/welcome-to-nz-now-pay-up-the-risks-and-rewards-of-raising-the-foreign-tourist-tax-232138">reducing visitor numbers</a> to protect the country’s unique landscapes and cultures.</p> <p>But are there other ways the tourism industry can evolve to ensure benefits for both travellers and the communities they are visiting? So called “slow travel” could be the answer.</p> <h2>Hunting the perfect photo</h2> <p>Overtourism isn’t just about too many people in one place. It’s also about <em>how</em> people travel.</p> <p><a href="https://edition.cnn.com/travel/social-media-tourism-effect-scn-wellness/index.html">Instagram-famous</a> landmarks draw massive crowds, <a href="https://www.rnz.co.nz/news/national/406195/visitors-ignore-ban-continue-to-visit-mermaid-pools-in-northland-hapu">disrupting local life</a> and sometimes even <a href="https://www.nzherald.co.nz/travel/vermot-town-famous-for-fall-foliage-bans-instagram-tourists-from-streets/BHKEYKKUTNHORFT6QCZ5TW333A/#google_vignette">leading to closures</a>.</p> <p>Travellers often pack their itineraries with as many sights as possible, racing from one place to another in a frenzy to capture the perfect photo. This hurried approach not only creates <a href="https://www.cntraveler.com/galleries/2015-06-19/barcelona-bhutan-places-that-limit-tourist-numbers">congestion</a> but also limits <a href="https://www.nature.com/articles/s41599-024-02859-z">meaningful engagement with the destination</a>.</p> <p>And it’s not just a numbers game. The way tourists behave also plays a critical role.</p> <p>A <a href="https://www.rnz.co.nz/national/programmes/ninetonoon/audio/2018690535/tropical-trash-the-impact-of-holidaying-in-the-pacific">2019 report</a> from the United Nations raised concerns about trash from tourists in developing small island states, including the Pacific Islands. According to the report, a tourist visiting these communities produced about 7kg of waste a day, compared to about 2.5kg produced by a local.</p> <p>The issue is not necessarily about travelling less, but about <a href="https://www.sciencedirect.com/science/article/pii/S2211973623000284">travelling more responsibly</a>. The tourism industry needs to be encouraging travel habits that allow both visitors and locals to enjoy tourism without compromising the integrity of the destination.</p> <h2>The rise of slow travel</h2> <p>Mindfulness – being fully present in the moment – has gained popularity since the 1970s. The concept has influenced a number of sectors, including <a href="https://slowfoodauckland.co.nz/">slow food</a>, <a href="https://ourwayoflife.co.nz/slow-fashion-101-what-to-buy-and-what-to-avoid-to-reduce-your-clothing-footprint/">slow fashion</a>, and now <a href="https://www.lakewanaka.co.nz/wanaka-stories/how-to-be-a-slow-mindful-traveler-in-wanaka/">slow travel</a>.</p> <p>It’s about <a href="https://link.springer.com/chapter/10.1007/978-3-031-63569-4_44#:%7E:text=Slow%20travel%2C%20mindful%20travel%2C%20or,spiritual%20well%2Dbeing%20of%20people">experiencing destinations</a> at a relaxed pace, focusing on deeper connections with local cultures and sustainability. This often means <a href="https://guestnewzealand.com/about-us/eco-travels-new-zealand/">staying longer in fewer places</a> and choosing eco-friendly transport.</p> <p>Understanding slow travel and mindfulness is important because they create <a href="https://www.forbes.com/sites/rogersands/2024/06/08/the-beauty-of-slow-travel/">richer, more memorable experiences</a>. Fast, <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">hectic travel</a> often leaves little positive impact. Slow immersive travel, on the other hand, fosters lasting memories and reduces overtourism, pollution and cultural damage.</p> <p><a href="https://www.tandfonline.com/doi/full/10.1080/00913367.2024.2325144">Research</a> shows when we consciously immerse ourselves in our surroundings we can have more meaningful experiences. Surprisingly, <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">even luxury travel</a> – often dismissed as wasteful – can encourage respect and mindfulness for those who invest financially and mentally in their journey, unlike cheaper, mainstream tourism.</p> <p>Activities such as “<a href="https://www.sciencedirect.com/science/article/pii/S2666957921000197">forest bathing</a>”, <a href="https://www.visitutah.com/articles/mindful-hiking">hiking</a> or engaging with <a href="https://www.outofyourcomfortzone.net/a-guide-to-slow-travel-immersing-yourself-in-local-cultures/">local cultures</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6723984/">boost wellbeing and meaning</a>, going beyond just “taking a photo for likes”.</p> <p>This mindful approach can <a href="https://www.sciencedirect.com/science/article/pii/S0160738321001419">change our behaviour on a personal level</a>. By focusing attention on fewer experiences, <a href="https://www.tandfonline.com/doi/full/10.1080/00913367.2024.2325144">travellers can heighten</a> their sense of awe and appreciation, making the travel more memorable.</p> <p>This idea is evident in “<a href="https://journals.sagepub.com/doi/abs/10.1177/002216786200200102?casa_token=PrIQTkCMjx0AAAAA:wtswfg0cuEuQec0zVg-Mbf9MuXYoqhQkWbaQCGdjxWkYUpVOwBu8Op5jC6V4nOghnow3xpwN3fDn">peak experiences</a>”. Disney, for example, creates <a href="https://ideaexchange.uakron.edu/docam/vol9/iss2/6/">emotionally-charged moments</a> that stick in visitors’ minds.

Even in busy places like Disneyland, focusing on one unique element can make the experience feel slower and more meaningful.</p> <h2>The sustainability of tourism</h2> <p>In the <a href="https://www.sciencedirect.com/science/article/pii/S0261517724000487">Faroe Islands</a>, slow travel helps protect local traditions and landscapes by encouraging thoughtful visitor behaviour, such as using local guides to minimise environmental impact.</p> <p>New Zealand can leverage its natural beauty to offer similar immersive experiences. <a href="https://www.nzherald.co.nz/travel/travel-well-what-is-mindful-hiking-walking-for-wellbeing-boost/67MYS6ZSNXC7ZH6OTZ2DLBGFL4/">Tramping</a> (hiking), for example, can promote a mindful connection with the environment.</p> <p>But even here, there needs to be a focus on balancing tourism with preservation. Popular spots, such as the Department of Conservation huts and the Te Araroa Trail, are <a href="https://www.wildernessmag.co.nz/te-araroa-trail-shows-pressure/">already becoming crowded</a>. It is essential to educate visitors on <a href="https://www.mpi.govt.nz/outdoor-activities/tramping-tips-to-prevent-spreading-pests-and-diseases/biosecurity-considerations-walking-and-tramping/">responsible practices</a> – such as cleaning equipment – to ensure they understand their <a href="https://www.doc.govt.nz/heritage-and-visitor-strategy#:%7E:text=The%20natural%2C%20cultural%20and%20historic,wellbeing%2C%20enabling%20communities%20to%20thrive.">role in protecting nature</a>.</p> <p>Travel that fosters a deeper appreciation for local cultures and environments benefits both visitors and the destinations they explore.

From maxing out to slowing down, how much do heart rates vary across sports?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/gregory-peoples-1556509">Gregory Peoples</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>A classic image of the Olympics and Paralympics is an athlete at the end of a race struggling for breath, their heart obviously racing.</p> <p>But at the other end of the scale are athletes such as archers and shooters, who need to slow their heart rates down as much as possible.</p> <p>Athletes in speed and endurance events regularly push their heart rate to the maximum. But these athletes usually have low heart rates at rest.</p> <p>What causes our heart rates and respiratory (breathing) rates to change so much, and is this healthy?</p> <h2>When heart rates and respiratory rates rise</h2> <p>If you are still and calm as you read this, your heart is probably beating 60–100 times per minute and you are likely breathing 12–20 times per minute.</p> <p>These are the <a href="https://theconversation.com/what-should-my-heart-rate-be-and-what-affects-it-98945">normal ranges for a resting adult</a>.</p> <p>During physical activity when muscles are contracting, the muscles need more oxygen to provide them with energy to work.</p> <p>To deliver this extra oxygen (<a href="https://theconversation.com/curious-kids-why-is-blood-red-229121#:%7E:text=Haemoglobin%20is%20like%20a%20red,oxygen%2C%20our%20blood%20is%20red.">carried in our blood</a>), our heart pumps blood faster. In other words, our heart rate increases.</p> <p>We also breathe faster to get more oxygen into our lungs to be delivered to the exercising muscles.</p> <figure><iframe src="https://www.youtube.com/embed/3YOap5k0R_8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Your resting heart rate can tell you plenty about your health and fitness.</span></figcaption></figure> <h2>How fast can our heart rate get during exercise?</h2> <p>Aerobic means “with oxygen”. In <a href="https://my.clevelandclinic.org/health/articles/7050-aerobic-exercise">aerobic exercise</a> (“cardio”) you use large muscles repetitively and rhythmically. For example, walking, running, cycling, swimming and rowing.</p> <p>Muscles that are contracting during aerobic exercise use a lot of energy and need ten times <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4551211/">more oxygen than at rest</a>.</p> <p>High intensity aerobic events that involve large muscles or the entire body cause the highest heart rates.</p> <p>An <a href="https://www.heartonline.org.au/resources/calculators/target-heart-rate-calculator">estimate</a> of maximum heart rate (beats per minute) is 220 minus your age. This equates to 195 beats per minute for a 25-year-old – close to the average age of the Australian Olympic team of 26.5 years.</p> <p>Athletes competing in Olympic events of endurance or speed will reach their maximum heart rate.</p> <p>You can usually only maintain maximum heart rate for a few minutes. But in a 2000-metre rowing race, the rowers maintain intense effort at close to maximum heart rate for 6–8 minutes.</p> <p>This is one of the toughest events for the heart. It’s no wonder rowers often collapse in the boat <a href="https://www.bbc.com/news/uk-england-cambridgeshire-68731840">as they cross the finish line</a>.</p> <p>Highly trained endurance athletes can have a maximum heart rate higher than expected for their age. <a href="https://olympics.com/en/athletes/eliud-kipchoge">Eliud Kipchoge</a> from Kenya is considered the greatest marathon runner of all time. During his <a href="https://au.coros.com/stories?world-record">world record run</a> in the 2022 Berlin marathon, he ran with a heart rate of around 180 beats per minute for almost the entire race.</p> <h2>How does breathing change with exercise?</h2> <p>Our breathing changes with exercise to increase oxygen uptake from the air.</p> <p>At low-to-moderate intensity exercise, you start to take deeper breaths. This brings in more air and oxygen with each breath. However, there is a limit to how much the chest can expand.</p> <p>With higher intensity exercise, respiratory rate increases to increase oxygen intake.</p> <p>Elite athletes can breathe <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4818249/">more than 50 times</a> per minute. This is driven by <a href="https://theconversation.com/what-is-breathwork-and-do-i-need-to-do-it-231192">our diaphragm</a>, the most important muscle of breathing.</p> <p><a href="https://www.abc.net.au/news/2024-07-28/paris-olympics-grace-brown-cycling-gold-medal-australia/104151466">Grace Brown</a>, Olympic gold medal cyclist in Paris, <a href="https://inscyd.com/article/grace-brown-olympic-gold-physiology/">breathes close to a maximal oxygen uptake</a> when she is cycling at high intensity.</p> <h2>Some athletes need to slow things down</h2> <p>Archery and shooting athletes perform better with a lower heart rate.

Captain Cook memorial vandalised ahead of January 26th

<p>A memorial honouring Captain Cook in Catani Gardens, St  Kilda has been vandalised ahead of Australia Day. </p> <p>The statue of the British colonialist was cleanly sawn off from its stone base, which was also defaced with red graffiti and the chilling message: “The colony will fall”.</p> <p>The memorial is believed to have been cut down around 3:30 am on Thursday, after members of the public alerted police. </p> <p>“Several people were seen loitering in the area around the time of the incident,” police said.</p> <p>Liberal MP Angus Taylor called the incident an “egregious act of vandalism" and said that it is one of the acts that "everyone should condemn.”</p> <p>“Captain Cook was a man of the enlightenment. Why would they do this to I think a great human being,” he said on <em>Today</em>.</p> <p>Port Phillip councillor Marcus Pearl described the incident as “disheartening” and called for the vandal to be held accountable for their actions. </p> <p>“This is not a solitary act of mischief,” he said.</p> <p>“It’s a repeated pattern of disrespect, especially evident around Australia Day for the past six years. Such acts blatantly disregard our community’s hard-fought principles of debate and democratic expression.”</p> <p>The Captain Cook statue has been a target of multiple vandalism attempts, with vandals covering it in bright coloured paint, both in 2018 and 2022. </p> <p>The Port Phillip councillor has urged people not to let this incident “fuel division” but instead drive “constructive, inclusive conversations." </p> <p>“Our community’s strength lies in its ability to engage in respectful and open discussions,” he said.</p> <p><em>Images: Today</em></p> <p> </p>

Victoria Beckham's cooking skills hilariously slammed by her own daughter

<p>Victoria Beckham's cooking skills have been playfully roasted by her daughter, Harper Beckham.</p> <p>In an Instagram story shared to her 31.4 million followers, the former Spice Girl documented a family baking session featuring herself, husband David Beckham, and their daughter Harper.</p> <p>David was filmed in the middle of whipping up an apple crumble using apples from the "Beckham Orchard," while Harper was busy baking chocolate chip cookies.</p> <p>While the father-daughter duo were channeling their inner baker, Victoria was filming the moment and asked Harper whether she inherited her culinary talents from her mum or dad.</p> <p>"Did you learn to cook from daddy or mummy?" Victoria asked Harper in the light-hearted clip.</p> <p>With a mischievous grin, Harper retorted, "Mummy, you can't even make cereal!"</p> <p>"Oh wow, Mummy can't even make cereal," Victoria responded. </p> <p>"Well you can make chicken Kiev but that comes from M&amp;S," the 12-year-old said, adding insult to injury. </p> <p>M&amp;S (Marks and Spencer) is the local British retailer, which specialises in clothing, food and home products among other things. </p> <p>Victoria hilariously captioned the video: "I get it Harper… I can't cook."</p> <p>The Beckhams often invite fans into their kitchen through their social media, and document their cooking escapades. </p> <p>Watch the full clip <a href="https://kitchen.nine.com.au/latest/harper-beckham-roasts-mum-victoria-beckham-cooking-skills-in-new-clip/e538cdaa-f295-427d-b334-4bb7351da1bd" target="_blank" rel="noopener">here</a>. </p> <p><em>Images: Instagram</em></p>

"I didn't do anything. I love them": Woman who cooked meal with deadly mushrooms speaks out

<p>A Victorian woman who cooked the meal that resulted in the suspected mushroom poisoning,  which left three elderly family members dead and one fighting for his life has tearfully broken her silence. </p> <p>Erin Patterson, 48, served the lunch to four people at Leongatha on July 29, including her former in-laws Don and Gail Patterson, who after falling sick later that evening, passed away from symptoms consistent with death cap mushroom poisoning.  </p> <p>Gail's sister Heather Wilkinson also passed away, with Heather’s husband, Ian in a critical condition at Melbourne’s Austin Hospital after suffering from the suspected poisoning. </p> <p>"I didn't do anything. I love them," Erin told  <em>A Current Affair. </em></p> <p>A clearly distraught Erin confused Don for Ian, who is currently being treated for his symptoms. </p> <p>"I'm devastated that they're gone and I hope with every fibre of my being that Don pulls through."</p> <p>“I’m so devastated by what’s happened, by the loss of Don, Don is still in hospital, by the loss of Ian and Heather and Gail," she repeated. </p> <p>“They were some of the best people I’ve ever met.</p> <p>“Gail was like the mum I didn’t have because my mum passed away four years ago, Gail had never been anything but good and kind to me,” she added.</p> <p>“Ian and Heather were some of the best people I’d ever met. They never did anything wrong to me.</p> <p>“I’m so devastated about what’s happened and the loss to the community and to the families and to my own children. They've lost their grandmother," she said, and added that she felt "so sorry" that they lost their lives.</p> <p>Erin was interviewed by police and later on released. Officials had also removed her two children from her care as a “precaution”. </p> <p>Homicide Squad Detective Inspector Dean Thomas also added that police are still determining whether this was an accident or a crime. </p> <p>“We’re working to determine what has gone on, to see if there is any nefarious activity that has occurred or if it was accidental.”</p> <p>“We have to keep an open mind,” he said.</p> <p>Police were also still unsure where the mushrooms were sourced from, and that it was a "complex case". </p> <p><em>Image: A Current Affair</em></p>

Cooking (and heating) without gas: what are the impacts of shifting to all-electric homes?

<p><em><a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Gas connections for all new housing and sub-divisions will be <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">banned in Victoria</a> from January 1 next year. The long-term result of the state government’s significant change to planning approvals will be all-electric housing. The ACT made <a href="https://www.climatechoices.act.gov.au/policy-programs/preventing-new-gas-network-connections">similar changes</a> early this year, in line with a shift away from gas across <a href="https://www.bbc.com/news/science-environment-47559920">Europe</a> and <a href="https://www.theguardian.com/environment/2023/jan/19/gas-stove-culture-war-united-states">other locations</a>, although the NSW Premier Chris Minns has <a href="https://www.theguardian.com/australia-news/2023/jul/31/nsw-wont-ban-gas-in-new-homes-as-premier-declares-i-dont-need-another-complication">baulked</a> at doing the same.</p> <p>Around <a href="https://www.energy.vic.gov.au/renewable-energy/victorias-gas-substitution-roadmap">80% of homes</a> in Victoria are connected to gas. This high uptake was driven by gas being seen as more affordable and sustainable than electricity over past decades. The situation has <a href="https://www.iea.org/events/net-zero-by-2050-a-roadmap-for-the-global-energy-system">changed dramatically</a> as renewable electricity generation increases and <a href="https://www.abc.net.au/news/2023-07-27/aemo-wholesale-electricity-prices-fall-impact-power-bills/102654498">costs fall</a>.</p> <p><a href="https://theconversation.com/all-electric-homes-are-better-for-your-hip-pocket-and-the-planet-heres-how-governments-can-help-us-get-off-gas-207409">Research</a> has suggested for more than a decade that the benefits of all-electric homes <a href="https://bze.org.au/research_release/energy-efficient-buildings-plan/">stack up in many locations</a>. New homes built under mandatory building energy performance standards (increasing from <a href="https://thefifthestate.com.au/innovation/building-construction/victoria-kicks-the-can-down-the-road-again-on-the-national-construction-code/">6 to 7 stars</a> in Victoria in May 2024) need smaller, cheaper heating and cooling systems. Installing reverse-cycle air conditioning for cooling provides a cost-effective heater as a bonus.</p> <p>Savings from not requiring gas pipes, appliances and gas supply infrastructure help to offset the costs of highly efficient electric appliances. Mandating fully electric homes means economies of scale will further reduce costs.</p> <h2>How does this ban help?</h2> <p>To achieve environmentally sustainable development, reforms of planning policy and regulation <a href="https://theconversation.com/sustainable-cities-australias-building-and-planning-rules-stand-in-the-way-of-getting-there-84263">are essential</a> to convert innovation and best practice to mainstream practice. Planning policy is particularly important for apartment buildings and other housing that may be rented or have an owners’ corporation. Retrofits to improve energy efficiency can be difficult in these situations.</p> <p>Banning gas in new and renovated housing will <a href="https://grattan.edu.au/report/getting-off-gas/">cut greenhouse gas emissions</a>. It’s also <a href="https://theconversation.com/gas-cooking-is-associated-with-worsening-asthma-in-kids-but-proper-ventilation-helps-151591">healthier for households</a> and <a href="https://www.sustainability.vic.gov.au/research-data-and-insights/research/research-reports/the-victorian-healthy-homes-program-research-findings">reduces healthcare costs</a> as well as <a href="https://grattan.edu.au/report/getting-off-gas/">energy bills and infrastructure costs</a>. The Victorian government suggests the change will save all-electric households <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">about $1,000 a year</a>. Houses with solar will be even better off.</p> <p>The government appears to be offering wide support to ensure these changes happen, but this will need to be monitored closely.</p> <p>Some households will face extra costs for electric appliances and solar panels. The government’s announcement of <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">$10 million</a> for Residential Electrification Grants should help with some of these costs while the industry adjusts.</p> <p>There will be impacts and benefits for the local economy. Some jobs may be lost, particularly in the gas appliance and plumbing industry. The government has announced financial support to retrain people and they will still have essential roles in the existing housing sector.</p> <p>Many gas appliances are imported, including ovens, cooktops and instantaneous gas water heaters. Some components of efficient electric products, such as hot water storage tanks, are made locally. Local activities, including distribution, sales, design, installation and maintenance, comprise much of the overall cost.</p> <h2>Challenges of change must be managed</h2> <p>Sustainability benefits will depend on what <a href="https://grattan.edu.au/report/getting-off-gas/">happens with the energy network</a>. We need more renewable energy, energy storage and smarter management of electricity demand.</p> <p>The shift to all-electric homes may mean winter peak demand for heating increases. Energy market operators and governments will have to monitor demand changes carefully to avoid the reliability issues we already see in summer. However, improving energy efficiency, energy storage and demand management will help reduce this load (and household costs).</p> <p>While the benefits are clear for new homes, the changes may <a href="https://www.bsl.org.au/research/publications/enabling-electrification/">increase gas costs and energy poverty</a> for residents of existing housing who don’t shift to efficient electric solutions. The government has reconfirmed financial rebates to help households switch from gas.</p> <p>In addition, existing housing may face building quality and performance issues. Some may require electrical wiring upgrades as part of the transition.</p> <p>Social acceptance of some electric appliances may also be an issue. For example, <a href="https://www.rmit.edu.au/about/schools-colleges/property-construction-and-project-management/research/research-centres-and-groups/sustainable-building-innovation-laboratory/projects/heet-housing-energy-efficiency-transitions">our research</a> has found some households dislike the way heating from reverse cycle air conditioners feels. Others do not like cooking on induction cooktops.</p> <p>Consumer education and modifications to appliances and buildings may be needed to increase acceptance and avoid backlash.</p> <p>Some electric appliances are available overseas but not in Australia. Higher demand may increase the range of imports. For example, floor-mounted heat pumps can make heating feel similar to gas heating while still providing effective cooling.</p> <p>We should not assume electric appliances are all equal. To improve consumer protection, action is needed on weak standards and limited and inconsistent public information. For example, information on noise levels and efficiency under a range of weather conditions must be standardised.</p> <p>Moving housing away from gas is an <a href="https://link.springer.com/book/10.1007/978-981-99-2760-9">important step</a> in the transition to a zero-carbon economy and energy system. Careful management is needed to ensure this transition is effective, accepted and fair.</p> <p>Continued planning reforms are also essential to ensure environmentally sustainable development of housing and communities. Other urgent priorities include urban cooling and greening, and <a href="https://theconversation.com/turning-the-housing-crisis-around-how-a-circular-economy-can-give-us-affordable-sustainable-homes-208745">circular economy approaches</a> to reduce the material and waste impacts of housing and thus the carbon that goes into building and running homes.<!-- Below is The Conversation's page counter tag.

Too big, too heavy and too slow to change: road transport is way off track for net zero

<p><a href="https://theconversation.com/profiles/robin-smit-594126">Robin Smit</a>, <em><a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p>The need to cut the emissions driving climate change is urgent, but it’s proving hard to decarbonise road transport in Australia. Its share of the nation’s total greenhouse gas emissions <a href="https://ageis.climatechange.gov.au/">doubled</a> from 8% in 1990 to 16% in 2020. New vehicles sold in Australia have <a href="https://theconversation.com/we-thought-australian-cars-were-using-less-fuel-new-research-shows-we-were-wrong-122378">barely improved</a> average emissions performance for the last decade or so.</p> <p>The federal government <a href="https://www.dcceew.gov.au/climate-change/publications/australias-emissions-projections-2022">publishes</a> emission forecasts to 2035 – 15 years short of 2050, the net-zero target date. Our <a href="https://www.transport-e-research.com/_files/ugd/d0bd25_7a6920bdd9e8448385863a7c23ec9ecf.pdf">newly published study</a> forecasts road transport emissions through to 2050. The estimated reduction by 2050, 35–45% of pre-COVID levels in 2019, falls well short of what’s needed.</p> <p>Our findings highlight three obstacles to achieving net zero. These are: Australia’s delay in switching to electric vehicles; growing sales of large, heavy vehicles such as SUVs and utes; and uncertainties about hydrogen as a fuel, especially for freight transport. These findings point to policy actions that could get road transport much closer to net zero.</p> <h2>How was this worked out?</h2> <p>Emissions and energy use vary from vehicle to vehicle, so reliable forecasting requires a detailed breakdown of the on-road fleet. Our study <a href="https://www.transport-e-research.com/software">used</a> the Australian Fleet Model and the net zero vehicle emission model (n0vem).</p> <p>The study focused on so-called <a href="https://www.cummins.com/news/2022/05/26/well-wheel-emissions-simplified">well-to-wheel emissions</a> from fuel production, distribution and use while driving. These activities account for about 75–85% of vehicle emissions. (<a href="https://theconversation.com/how-climate-friendly-is-an-electric-car-it-all-comes-down-to-where-you-live-179003">Life-cycle assessment</a> estimates “cradle-to-grave” emissions, including vehicle manufacture and disposal.)</p> <p>Working with European Union colleagues, our emissions simulation drew on an updated <a href="https://www.transport-e-research.com/_files/ugd/d0bd25_7a6920bdd9e8448385863a7c23ec9ecf.pdf">EU scenario</a> (EU-27) showing the changes in the EU vehicle fleet needed to meet the latest (proposed) CO₂ targets. Our study assumed Australia will be ten years behind the EU across all vehicle classes.</p> <p>We further modified the scenario to properly reflect Australian conditions. For instance, the EU has a much higher proportion of plug-in hybrid vehicles than Australia, where buyers are now bypassing them for wholly electric vehicles.</p> <h2>Energy use is shifting, but too slowly</h2> <p>Using this modified scenario, the simulation produces a forecast fall in total wheel-to-wheel emissions from Australian transport from 104 billion tonnes (Mt) in 2018 to 55-65Mt in 2050. Within the range of this 35–45% reduction, the outcome depends largely on the balance of renewable and fossil-fuel energy used to produce hydrogen.</p> <p>The modelling nonetheless predicts a large shift in energy use in road transport in 2050, as 2019 was basically 100% fossil fuels.</p> <p>The on-road energy efficiency of battery electric vehicles is roughly twice that of fuel cell electric (hydrogen) vehicles and roughly three times that of fossil-fuelled vehicles of similar type.</p> <p>The modelling results make this clear. In 2050, battery electric vehicles account for about 70% of total travel, but 25% of on-road energy use and only about 10% of total emissions.</p> <p>In contrast, fossil-fuelled vehicles account for about 25% of total travel in 2050, 60% of energy use and 75-85% of emissions. That’s even allowing for expected efficiency improvements.</p> <p>This means the shift to a mostly electric fleet by 2050 plus the use of hydrogen is predicted to fall short of what’s needed to get to net zero. It will require aggressive new policies to increase the uptake of electric vehicles across all classes.</p> <h2>Lighter vehicles make a big difference</h2> <p>But that is not the whole story. One neglected issue is the growing proportion of <a href="https://theconversation.com/we-may-be-underestimating-just-how-bad-carbon-belching-suvs-are-for-the-climate-and-for-our-health-190743">big, heavy passenger vehicles</a> (SUVs, utes). This trend is very noticeable in Australia. The laws of physics mean heavier vehicles need much more energy and fuel per kilometre of driving, and so produce more emissions.</p> <p>Currently, a large diesel SUV typically emits a kilogram of CO₂ for every 3 kilometres of driving, compared to 15km for a light electric vehicle and 200 kilometres for an e-bike. An average electric vehicle currently emits 1kg of CO₂ every 7km.</p> <p>This distance is expected to be around 60km in 2050, when renewables power the electricity grid. A lightweight electric car will more than double the distance to 125km per kilogram of CO₂. Reducing vehicle weights and optimising energy efficiency in transport will be essential to meet emission targets.</p> <p>The study modelled the impacts of <a href="https://www.automotiveworld.com/special-reports/vehicle-lightweighting-2/">lightweighting</a> passenger vehicles while keeping buses and commercial vehicles the same. If Australians had driven only small cars in 2019 for personal use, total road transport emissions would have been about 15% lower.</p> <p>The reduction in emissions from simply shifting to smaller cars is <a href="https://www.dcceew.gov.au/climate-change/publications/national-greenhouse-accounts-2019/national-inventory-report-2019">similar to</a> emissions from domestic aviation and domestic shipping combined. Importantly, lightweighting cuts emissions for all kinds of vehicles.</p> <h2>The uncertainties about hydrogen</h2> <p>Fuel cell electric vehicles using hydrogen account for only a few percent of all travel, but most will likely be large trucks. As a result, in our scenarios, they use a little over 10% of total on-road energy and produce 5-20% of total emissions, depending on the energy source used for hydrogen production and distribution.</p> <p>The modified EU scenario includes a significant uptake of hydrogen vehicles by 2050. That’s by no means guaranteed.</p> <p>The uptake in Australia has been negligible to date. That’s due to costs (vehicle and fuel), the need for new hydrogen fuel infrastructure, less mature technology (compared to battery electric vehicles) and limited vehicle availability. <a href="https://theconversation.com/we-must-rapidly-decarbonise-transport-but-hydrogens-not-the-answer-166830">Unresolved aspects</a> of hydrogen in transport include lower energy efficiency, the <a href="https://theconversation.com/for-australia-to-lead-the-way-on-green-hydrogen-first-we-must-find-enough-water-196144">need for clean water</a>, uncertainty about leakage, fuel-cell durability and value for consumers.</p> <h2>How do we get back on track?</h2> <p>Our study suggests Australia is on track to miss the net-zero target for 2050 mainly because of the large proportions of fossil-fuelled vehicles and large and heavy passenger vehicles.</p> <p>These two aspects could become targets for new policies such as public information campaigns, tax incentives for small, light vehicles, bans on selling fossil fuel vehicles and programs to scrap them. Other options to cut emissions include measures to reduce travel demand, optimise freight logistics and shift travel to public transport, to name a few.</p> <p>The study confirms the scale of the challenge of decarbonising road transport. Australia will need “all hands on deck” – government, industry and consumers – to achieve net zero in 2050.<!-- Below is The Conversation's page counter tag.

"Forgotten pizza cook" Pete Evans' wild new look

<p dir="ltr">Former Seven personality Pete Evans has made an unexpected appearance on social media, though many took a moment longer than usual to realise who it was they were looking at in the clip.</p> <p dir="ltr">The former chef and <em>My Kitchen Rules</em> judge was a far cry from the polished persona audiences had come to expect from his days at the helm of the hit cooking competition, roaming through an outdoor kitchen in a ‘Food is Medicine’ t-shirt and unexpected mullet cut.</p> <p dir="ltr">The footage marked a new chapter in Evans’ public fall from grace, and as one account sharing the content wrote, it had “captured a quick raw video of the set up” for a cooking retreat with eight guests and “approx 25 recipes”.</p> <p dir="ltr">It did provide some insight into Evans’ new ‘career’ path, with the chef having turned his back on the entertainment industry in 2020, after 11 years as a household name hosting <em>My Kitchen Rules</em>. </p> <p dir="ltr">His controversial opinions on health - and his mounting support in conspiracy theories as well as his non-scientifics views - had initially turned attention his way, but it was his take on the global COVID-19 pandemic that sealed his fate. </p> <p dir="ltr">Also in 2020, Evans received a $25,000 fine from the TGA for his part in peddling a $15,000 ‘Biocharger’ device with the incorrect claim that it could combat the coronavirus.</p> <p dir="ltr">Evans was quickly removed from social media - namely Facebook and Instagram - for spreading misinformation during the pandemic, and lost 15 different sponsors in just 38 hours after sharing a meme that contained a neo-Nazi symbol with his remaining followers. It was estimated that the latter act alone could cost Evans millions of dollars.</p> <p dir="ltr">In the time since, Evans has purchased a $1 million tourist ‘healing’ retreat close to Byron Bay, where he offers the likes of ‘fasting retreats’ - charging $2250 a head for a “5-day juice, water, and froth fast” with Evans.</p> <p dir="ltr">When news of the venture broke on social media, opinion poured in thick and fast, with most condemning the experience. </p> <p dir="ltr">However, it wasn’t enough to keep Evans from returning to the internet, with the 50-year-old launching his presence on the alternative platform, Telegram, where he shares the likes of detail on his retreats, his experience with bitcoin, anti-vaccination takes, and right-wing political opinion.</p> <p dir="ltr">As one user wrote in response - and on behalf of the majority - to the fresh footage of the disgraced chef, “I won’t have what he’s having”. </p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Obviously vaccines are bad. Not ‘licking toads’ though. That’s cool.

Is it true the faster you lose weight the quicker it comes back? Here’s what we know about slow and fast weight loss

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>When people decide it’s time to lose weight, they’re usually keen to see quick results. Maybe they have an event coming up or want relief from health problems and discomfort.</p> <p>But expert guidelines typically recommend slower weight loss for the treatment of obesity. This tallies with a a widely held opinion that fast weight loss is more quickly regained. Slow weight loss is generally perceived as better for your health and more sustainable. Many programs offering “the fastest way to lose weight” are considered fad diets that severely restrict calories or eliminate some foods.</p> <p>But does slow and steady really win the weight-loss race? Or is fast weight loss just as effective and safe?</p> <h2>What’s the difference between slow and fast weight loss?</h2> <p>Governing bodies typically <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/weight-loss-a-healthy-approach">recommend</a> a weight loss of 0.5 to 1 kilogram each week, which would be defined as slow weight loss.</p> <p>So <a href="https://medlineplus.gov/ency/patientinstructions/000885.htm#:%7E:text=Rapid%20weight%20loss%20diet%20is,a%20week%20over%20several%20weeks.">fast weight loss</a> – also termed “rapid weight loss” – is losing more than 1 kilo a week over several weeks.</p> <h2>What does the research say about fast weight loss?</h2> <p>There are several well-conducted studies examining differing approaches.</p> <p>One <a href="https://pubmed.ncbi.nlm.nih.gov/25459211/">study</a> of 200 people randomly assigned them to fast or slow weight loss – 12 weeks versus 36 weeks – aimed at a 15% reduction in weight.</p> <p>The fast weight loss group was put on a very low energy diet using meal replacements, including shakes, bars and soups, three times per day. The slow weight loss group was advised on the <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">Australian Guide to Healthy Eating</a> with the goal to eat 500 calories less than they used for energy (creating a calorie deficit) each day. They also used one to two meal replacements daily.</p> <p>Some 50% of the slow weight loss group and 81% of the fast weight loss group achieved 12.5% or more weight loss during this time.</p> <p>After this initial phase, those who had lost 12.5% or more were then placed on a weight maintenance diet for approximately 2.75 years.</p> <p>By the three-year mark, 76% of those in the slow weight loss and the same percentage of those in the fast weight loss group had regained their lost weight.</p> <p>So, it didn’t matter if they had lost it slow or fast, they still regained the weight.</p> <p>However, another <a href="https://www.sciencedirect.com/science/article/pii/S2405844020308513#bib17">study</a> on 101 postmenopausal women found fast weight loss resulted in better outcomes than a slow weight loss group at the three-year mark.</p> <p>But there are other factors to consider, aside from weight loss, when it comes to the differing ways of losing weight – such as changes in body composition and bone mineral density.</p> <p>This is best highlighted by a large <a href="https://pubmed.ncbi.nlm.nih.gov/32576318/">meta-analysis</a>. These type of studies combine the results of all previous well-conducted studies on the topic.</p> <p>While this <a href="https://pubmed.ncbi.nlm.nih.gov/32576318/">analysis</a> found the magnitude of weight loss was similar for both approaches, slow weight loss resulted in better outcomes than fast weight loss with respect to metabolism or how many calories we burn at rest.</p> <p>There were no differences in the amount of fat-free mass or muscle mass lost between the slow and fast weight loss groups. But slow weight loss resulted in greater reductions in fat mass and therefore a better fat-to-muscle ratio.</p> <p>Slow weight loss also seems better for bone density, because rapid weight loss results in a <a href="https://www.sciencedirect.com/science/article/pii/S2405844020308513#bib17">twice as much bone loss</a> and puts a person at increased risk of brittle bones or osteoporosis.</p> <h2>What about other diet approaches?</h2> <p>Research shows it doesn’t matter what type of macronutrient diet you follow – moderate or high-protein diet, low or high-carbodyrate diet, low or high-fat diet. All diet approaches achieve similar <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa0804748">weight loss outcomes</a>.</p> <p>The same can be said for fashionable ways of cutting calories from the diet, such as intermittent fasting. <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2114833">Research</a> has shown such diets don’t result in any better weight loss results than any of its predecessors. This is because our body is extremely good at <a href="https://theconversation.com/whats-the-weight-set-point-and-why-does-it-make-it-so-hard-to-keep-weight-off-195724">protecting against weight loss</a>.</p> <h2>When you want to lose weight consider …</h2> <p><strong>Your metabolism</strong> When you lose large amounts of weight, you resting metabolic rate – the energy you burn at rest – will lower. Keeping your resting metabolic rate high is essential for keeping the weight off. Unfortunately, once it slows down, your resting metabolic rate doesn’t recover to the level it was pre-dieting <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/oby.21538">even after you regain weight</a>.</p> <p>However, research has confirmed <a href="https://pubmed.ncbi.nlm.nih.gov/32576318/">slow weight loss</a> preserves your resting metabolic rate compared with rapid weight loss. As does a weight loss program <a href="https://www.sciencedirect.com/science/article/pii/S2161831323002867?via%3Dihub">that includes exercise</a> rather than one that focuses on diet alone.</p> <p><strong>Side effects</strong> While restrictive diets can achieve rapid results, studies suggest they can come with adverse effects. This includes a <a href="https://pubmed.ncbi.nlm.nih.gov/16350561/">higher risk of gallstones</a> and deficiencies that can result in poor immune function, fatigue and a <a href="https://pubmed.ncbi.nlm.nih.gov/32613096/">decrease in bone density</a>. Such restrictive diets can make it challenging to meet your nutritional needs.</p> <p><strong>Sustainability</strong> Many fast weight loss diets restrict or exclude foods required for long-term health. Carbohydrates are often banned, yet wholegrain carbohydrates are an essential source of nutrition, helping with weight loss and <a href="https://www.sciencedirect.com/science/article/pii/S0002822301001948">prevention of disease</a>. Including meal replacements as part of a restrictive diet is also not sustainable for long.</p> <h2>The bottom line?</h2> <p>Regardless of how you lose the weight, it’s very difficult to maintain losses. Our bodies work to keep our weight around a <a href="https://theconversation.com/whats-the-weight-set-point-and-why-does-it-make-it-so-hard-to-keep-weight-off-195724">set point</a> by adjusting our biological systems and imposing a series of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4766925/">physiological changes</a> within the body to ensure we regain weight we lose. This stems from our hunter-gatherer ancestors, whose bodies developed this survival response to adapt to periods of deprivation when food was scarce.</p> <p>Successful long-term weight loss comes down to:</p> <p><strong>1.</strong> following evidence-based programs based on what we know about the science of obesity</p> <p><strong>2.</strong> losing weight under the supervision of qualified health-care professionals</p> <p><strong>3.</strong> making gradual changes to your lifestyle – diet, exercise and sleep – to ensure you form health habits that last a lifetime.</p> <p>At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

5 negotiation tactics to grab crazy property deals in a slowing market

<p>Rising interest rates have started to put the handbrakes on Australia’s runaway property market, and that’s good news for homebuyers who are now in a far stronger position to negotiate on a property than they have been over the last few years.</p> <p>One of the most apparent advantages for buyers in the current market is the reduced levels of competition. Fewer buyers mean that prices aren’t being driven higher, and if you’re a good negotiator, it’s possible to swoop in and find yourself a bargain.</p> <p>If you’re new to negotiating for property or unsure where to start, here are five tactics that will help you achieve a strong result at the negotiating table.</p> <ol> <li><strong>Know the market</strong></li> </ol> <p>You can’t succeed in a negotiation if you don’t know the value of the asset that you’re trying to buy in the first place. That’s why any good negotiator will always start by doing their research. You need to know the market better than your competition and don’t get caught up in any hype or opinions from a sales agent.</p> <p>Start by finding what comparable properties are selling for in the market. Look for the last three months of sales around your property. The sales should be of similar property types, sizes, ages, and land components. Another good way to get an idea of the price is to speak with local agents in the area. When you have a fair market value, you then know your “walk away price,” and you won’t find yourself getting emotional and overbidding.</p> <ol start="2"> <li><strong>Understand the vendor’s motivations</strong></li> </ol> <p>In any negotiation, there is a saying that whoever needs the deal least will likely be the one that comes out on top. When looking at potential properties to buy, you can be the world’s best negotiator, but if the vendor doesn’t need to sell, they will likely either wait for their price or walk away.</p> <p>Whenever you start looking at a property, try to ascertain as much information about the vendor as possible. That will give you an understanding of how motivated they are to sell, which will then impact how much you initially want to offer.</p> <ol start="3"> <li><strong>Be the strong bidder, not the highest</strong></li> </ol> <p>In a property transaction, price is just one piece of the puzzle. When a vendor weighs up an offer on their property, they are interested in the price, but the terms can also play a big part.</p> <p>For example, if you’re a cash buyer who can settle quickly, that might be far more appealing to a vendor than a higher offer that needs three months to settle. Similarly, a larger deposit could give a vendor more certainty that the transaction will occur.</p> <p>As a buyer, getting your finances in place ahead of time and then tailoring your terms to suit the vendor might give you an edge in a negotiation even if you’re not the highest bidder. Ultimately, the vendor wants their problem solved, and your job is to find out what it is and then make a strong offer that addresses those immediate needs.</p> <p>If you are ever tempted to make an unconditional offer, be sure you’ve done extensive due diligence and can secure finance, as there could be significant costs if you have to back out of the deal.</p> <ol start="4"> <li><strong>Unique offers</strong></li> </ol> <p>A great way to make your offer seem stronger than it might actually be is to come in with an odd-numbered amount. An offer price of $596,200 instead of $590,000 or $600,000 reflects that you’ve taken the time to do your due diligence, making your offer stand out.</p> <p>Another approach is to make a written offer with a deadline. That way, you can speed up the negotiation process, and it might prevent the sales agent from pitting your bid against another buyer to drive up the price.</p> <ol start="5"> <li><strong>Know the property</strong></li> </ol> <p>It’s critical to clearly understand what you’re buying before entering any negotiation. While you might have done your comparable sales analysis and have an excellent overall picture of what similar properties are selling for, you still need to investigate this particular property.</p> <p>Several things can impact the property’s value, which can help you negotiate. For example, if an awkward tenant occupies the property, it will be less appealing to many homebuyers, which you can use to your advantage. There may also be issues with the property, such as problematic zoning, service locations, or even large trees that can alter its value.</p> <p>The most obvious factor to consider is the state of the property and whether it needs renovation or repairs. In the current market, homebuyers are less interested in buying a property that needs work due to the cost of materials and difficulty finding tradespeople. That will give you a strong starting point to negotiate around the price.</p> <p>While getting a great deal is essential, it’s crucial not to compromise on the property’s quality. Quality is more important than a bargain, and a property’s performance will ultimately determine its value.</p> <p>A slowing real estate market presents an opportunity for buyers to negotiate and secure a great property deal. By understanding the local market, paying attention to the vendor’s motivations, and putting forward intelligent offers, you can potentially grab an excellent property deal in a slowing market.</p> <p><strong><em>Rasti Vaibhav is the author of The Property Wealth Blueprint (RRP $39.95) and Founder of Get RARE Properties, a bespoke independent buyers' agency that has been helping hundreds of clients across Australia secure their financial freedom through property. </em></strong></p> <p><strong><em>For more information, visit <a href="https://getrare.com.au">https://getrare.com.au</a></em></strong></p> <p><em>Image credits: Getty Images</em></p> <p style="margin: 0px; font-stretch: normal; font-size: 12px; line-height: normal; font-family: Helvetica; color: #0d0d14; min-height: 14px;"> </p>

Slowing down in old age may point to a more sinister concern

<p dir="ltr">It’s widely accepted that we tend to lose muscle strength and general mobility as we get older, which tends to make completing general tasks, and simply moving through the world, more difficult. </p> <p dir="ltr">While these aches and pains are a common symptom of getting older, new <a href="https://www.ecu.edu.au/schools/medical-and-health-sciences/our-staff/profiles/post-doctoral-research-fellows/dr-marc-sim">research</a> conducted by the Edith Cowan University (ECU) indicates this could also be a signal for another sinister health concern of ageing: late-life dementia.</p> <p dir="ltr">Research teams from ECU’s Nutrition &amp; Health Innovation Research Institute and Centre for Precision Health have investigated the link between muscle function and dementia, examining more than 1000 women with an average age of 75. </p> <p dir="ltr">In collaboration with the University of Western Australia, the team measured the women’s grip strength and the time it took for them to rise from a chair, walk three metres, turn around and sit back down — known as a timed-up-and-go (TUG) test.</p> <p dir="ltr">These tests were repeated after five years to monitor any loss of physical performance.</p> <p dir="ltr">Over the next 15 years, almost 17 per cent of women involved in the study were found to have had a dementia event, categorised as a dementia-related hospitalisation or death.</p> <p dir="ltr">The team found lower grip strength and slower TUG were significant risk factors for presenting with dementia, independent of genetic risk and lifestyle factors such as smoking, alcohol intake and physical activity levels.</p> <p dir="ltr">The women with the weakest grip strength were found to be more than twice as likely to have a late-life dementia event than the strongest individuals. </p> <p dir="ltr">A similar relationship emerged between TUG performance and dementia, with the slowest in their TUG test more than twice as likely to experience dementia than the quickest.</p> <p dir="ltr">Senior researcher Dr Marc Sim said grip strength may be a measure of brain health due to the overlapping nature of cognitive and motor decline.</p> <p dir="ltr">“Possibly due to a range of underlying similarities, grip strength may also present as a surrogate measure of cardiovascular disease, inflammation and frailty, which are known risk factors for dementia,” Dr Sim said.</p> <p dir="ltr">Dr Sim went on to say that the findings could help healthcare professionals to identify dementia risk in patients earlier.</p> <p dir="ltr">“Incorporating muscle function tests as part of dementia screening could be useful to identify high-risk individuals, who might then benefit from primary prevention programs aimed at preventing the onset of the condition such as a healthy diet and a physically active lifestyle.”</p> <p dir="ltr">“The exciting findings were that decline in these measures was associated with substantially higher risk, suggesting that if we can halt this decline, we may be able to prevent late-life dementias.”</p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

Cooking mistakes that are making your food unhealthy

<p><strong>Boiling your veggies</strong></p> <p>A review published in the <em>International Journal of Gastronomy and Food Science</em> in 2016 showed that boiling vegetables resulted in a high loss of vitamin C and folate. One study found that broccoli, for example, lost about 33 per cent of its vitamin C. “Water-soluble vitamins leach out,” says Nishta Saxena, a registered dietitian. “If you’re not using the fluids in something like a soup, you’re missing out on nutrients.”</p> <p><strong>Rinsing raw chicken</strong></p> <p>While your favourite old cookbooks likely tell you to rinse a chicken before roasting, this outdated advice is a safety hazard. Running poultry under the tap may remove some of the bacteria (including salmonella and campylobacter, which can cause diarrhoea, vomiting and fever), but it’s also likely to transfer it around your kitchen –as far as nearly one metre from the sink, according to research from Drexel University in Philadelphia. “Droplets can spread from your hands to counter­tops and even onto the floor, which can be a concern, especially if you have small children,” says Saxena. To stay safe, skip the rinse and wash your hands thoroughly after you’re finished prepping your bird.</p> <p><strong>Removing skins from produce</strong></p> <p>Peeling your produce rids your food of an important layer of nutrients. “Significant amounts of vitamins, minerals and fibre are found in the skins,” says Liz Powell, a registered dietitian. Researchers at the University of Maine estimate that the skins of potatoes, for example, contain 10 to 12 times more antioxidants than the flesh. Peeling fruits and vegetables also strips away a dose of insoluble fibre, which is crucial for digestion and bowel function. Concern about herbicide or pesticide residue isn’t a good enough reason to forego the peelings, says Powell. Washing your fresh produce will remove some pesticide residues from the surface, she says. You can also opt for organic varieties of heavily sprayed produce, such as peaches.</p> <p><strong>Blending everything</strong></p> <p>A smoothie is a smart way to sneak in some greens (and down your breakfast in a hurry), but liquid meals tend to be unbalanced. They’re often lacking in protein, healthy fat and complex carbohydrates. These components work together to keep us feeling full and satisfied, Powell says. “Without them, it’s not really a balanced meal.” Powell recommends adding a scoop of yoghurt or protein powder and part of an avocado or a spoonful of hemp hearts for protein and fat. To sneak in a complex carb, you can add some oats to the blender or have a piece of wholegrain toast on the side, she says.</p> <p><strong>Overdressing salads</strong></p> <p>“Salads have this health halo – we think we can add anything to them and they’ll still be a nutritious choice, but it’s just not true,” says Saxena. “If you’re topping your bowl with dried cranberries, candied pecans and a sweet goat cheese, you’ve easily added 30 grams of sugar to your so-called healthy lunch.” Chopped, raw nuts and seeds are better options to beef up the flavour profile of your greens. Oil-based dressings also tend to be more nutritious than their creamy counterparts.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/home-tips/cooking-mistakes-that-are-making-your-food-unhealthy" target="_blank" rel="noopener">Reader's Digest</a></em>. </p>

8 air fryer cooking tips you need to know

<p><strong>Check your air fryer's temperature</strong></p> <p>Just like with ovens, temperatures may vary between air fryer models. Test your air fryer to see if it runs above or below the selected temperature setting. You’ll want your fryer nice and hot.</p> <p><strong>Know your air fryer's cooking times</strong></p> <p>Since air fryer temperatures vary, so do cook times. That’s why air fryer recipes have wider time ranges. So, to find your air fryer cooking times you’ll need to experiment. Start checking the food at the shortest time, and check back a little later if it’s not done.</p> <p><strong>Give it a shake (or a flip)</strong></p> <p>To help food crisp, always turn, rotate, or shake contents in air fryer basket (just like flipping French fries, fish fillets, or homemade chicken strips halfway through cooking in a traditional oven).</p> <p><strong>Cook food in a single layer for best results</strong></p> <p>Allow plenty of air circulation to get even cooking and crispy results. One exception where you can stack and pack foods is if you’re roasting veggie side dishes in the air fryer. For instance, you can load the basket with a 400 grams of Brussels sprouts and roast them at 180° for 12-15 minutes, stirring once.</p> <p><strong>Bake up a little treat</strong></p> <p>Yes, you can bake homemade cookies in the air fryer! All it takes is a few minutes and chilled dough on stand-by. Models differ in their “baking” functions, so test just one or two cookies at first. You may need to adjust the temperature or cooking time.</p> <p><strong>Seeing smoke? Here's what to do </strong></p> <p>First off, don’t panic. Simply unplug the air fryer and remove the food basket. Make sure no food is lodged in the heating coil. Return food to the air fryer and continue cooking. If smoke persists, there may be oil or residue on the heating element. Unplug the machine, cool, and then wipe the coil clean with a damp cloth, just like the heating coil on an electric stove. From now on, make sure to clean your air fryer regularly.</p> <p><strong>Use a thermometer when cooking meat</strong></p> <p>Because the food can brown nicely on the outside before reaching an appropriate temperature on the inside, checking the temp with a meat thermometer is an important step for safety. That goes for previously frozen foods and fresh ones.</p> <p><strong>It's a quick option when cooking for one or two </strong></p> <p>Any more than that, and you may have to cook in batches – so be sure to account for that in your timing.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/8-air-fryer-cooking-tips-you-need-to-know" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Historic Swedish sailing ship slow to give up its secrets

<div> <p>The Swedish ship Vasa was supposed to be a beacon of military might when it launched in 1628, but it sank after sailing just over a kilometre, killing roughly 30 people  in the process.</p> <p>Since its recovery in 1961, the ship, its contents and the people who perished with it have become a valuable insight into 17th-century Swedish life.</p> <p>Now, an international team of researchers has looked closer at one of the skeletons, referred to as G, and have confirmed that it’s female.</p> <p>“Through osteological analysis it has been possible to discover a great deal about these people, such as their age, height and medical history. Osteologists recently suspected that G could be female, on the basis of the pelvis. DNA analysis can reveal even more,” says Dr Fred Hocker, director of research at the Vasa Museum, Sweden.</p> <p>“It is very difficult to extract DNA from bone which has been on the bottom of the sea for 333 years, but not impossible”, says Professor Marie Allen, a forensic geneticist at Uppsala University in Sweden.</p> <p>“Already some years ago we had indications that skeleton G was not a man but a woman. Simply put, we found no Y-chromosomes in G’s genetic material. But we could not be certain and wanted to confirm the result.”</p> <p>They were able to do that with a technique developed by the US Department of Defense’s Armed Forces Medical Examiner System’s Armed Forces DNA Identification Laboratory (AFMES-AFDIL).</p> <p>“We took new samples from bones for which we had specific questions. AFMES-AFDIL has now analysed the samples, and we have been able to confirm that G was a woman, thanks to the new test,” says Allen.</p> <p>Allen, along with AFMES-AFDIL collaborator Dr Kimberly Andreaggi, is now investigating the DNA for more detail about G.</p> <p>“Today we can extract much more information from historic DNA than we could earlier and methods are being continuously refined. We can say if a person was predisposed to certain illnesses, or even very small details, such as if they had freckles and wet or dry ear wax,” says Allen.</p> <p>The Vasa Museum, meanwhile, is collecting information for a book about the people who died on the ship.</p> <p>“We want to come as close to these people as we can. We have known that there were women on board Vasa when it sank, and now we have received confirmation that they are among the remains,” says museum historian Dr Anna Maria Forssberg.</p> <p>“I am currently researching the wives of seamen, so for me this is especially exciting, since they are often forgotten even though they played an important role for the navy.”</p> </div> <div id="contributors"> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/history/vasa-shipwreck-female/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian. </em></p> <p><em>Images: Getty</em></p> </div>

Chris Hemsworth to slow down in Hollywood

<p>Chris Hemsworth has revealed he’s taking a break from acting following the news that he is at very high risk of developing Alzheimer’s disease later in life.</p> <p>While he may be slowing down, <em>Page Six </em>reported that the Aussie actor’s upcoming schedule is not quite so idle.</p> <p>Hemsworth has four projects in the works, including the return of his iconic <em>Thor</em> character in the highly anticipated <em>Avengers</em> sequel, and an untitled Hulk Hogan biopic. Although after those four projects, a source said, “he doesn’t plan to take on many roles because of [learning about his high risk for] Alzheimer’s.”</p> <p>Speaking to <em>Vanity Fair</em>, Hemsworth, 39, said he’s “not talking about retiring by any means,”</p> <p>The 39-year-old discovered he’s at high risk for Alzheimer’s while filming the National Geographic and Disney+ docuseries, <em>Limitless</em>.</p> <p>He told <em>Vanity Fair</em> about “the intensity [of] navigating” the test results and highlighted while it’s not a diagnosis, it’s a scary sign that the disease is more likely to develop in him than most other people.</p> <p>“Most of us, we like to avoid speaking about death,” he said. “Then to all of a sudden be told some big indicators are actually pointing to this as the route which is going to happen, the reality of it sinks in. Your own mortality.”</p> <p>He revealed learning that he’s “eight to 10 times more likely” to develop Alzheimer’s, “triggered something in me to want to take some time off.”</p> <p>“I’ve been completing the things I was already contracted to do,” he said, adding that he plans to “go home and … to have a good chunk of time off and just simplify. Be with the kids, be with my wife.”</p> <p><em>Image credit: Getty</em></p>

Tangy apricot Bavarian whip, fried rice medley and bombe Alaska: what Australia’s first food influencer had us cooking

<p>Our food choices are being influenced every day. On social media platforms such as YouTube, Instagram and TikTok, food and eating consistently appear on lists of trending topics. </p> <p>Food has eye-catching appeal and is a universal experience. Everyone has to eat. In recent years, viral recipes like <a href="https://www.washingtonpost.com/food/2021/02/11/baked-feta-pasta-recipe-tiktok/">feta pasta</a>, <a href="https://theconversation.com/what-is-dalgona-coffee-the-whipped-coffee-trend-taking-over-the-internet-during-coronavirus-isolation-137068">dalgona coffee</a> and <a href="https://theconversation.com/are-butter-boards-bad-for-you-an-expert-view-on-the-latest-food-trend-192260">butter boards</a> have taken the world by storm. </p> <p>Yet food influencing is not a new trend. </p> <p>Australia’s first food influencer appeared in the pages of Australia’s most popular women’s magazine nearly 70 years ago. Just like today’s creators on Instagram and TikTok, this teenage cook advised her audience what was good to eat and how to make it.</p> <h2>Meet Debbie, our teenage chef</h2> <p>Debbie commenced her decade-long tenure at the Australian Women’s Weekly in <a href="http://nla.gov.au/nla.news-page4814245">July 1954</a>. We don’t know exactly who played the role of Debbie, which was a pseudonym. Readers were never shown her full face or body – just a set of disembodied hands making various recipes and, eventually, a cartoon portrait.</p> <p>Like many food influencers today, Debbie was not an “expert” – she was a teenager herself. She taught teenage girls simple yet fashionable recipes they could cook to impress their family and friends, especially boys. </p> <p>She shared recipes for <a href="http://nla.gov.au/nla.news-page4925379">tangy apricot Bavarian whip</a>, <a href="http://nla.gov.au/nla.news-page4819441">fried rice medley</a> and <a href="http://nla.gov.au/nla.news-page4807813">bombe Alaska</a>. Debbie also often taught her readers the basics, like <a href="http://nla.gov.au/nla.news-article52249448">how to boil an egg</a>.</p> <p>Just like today, many of her recipes showed the readers step-by-step instructions through images.</p> <h2>Teaching girls to cook (and be ‘good’ women)</h2> <p>Debbie’s recipes first appeared in the For Teenagers section, which would go on to become the Teenagers Weekly lift-out in 1959. </p> <p>These lift-outs reflected a major change taking place in wider society: the idea of “teenagers” being their own group with specific interests and behaviours had entered the popular imagination.</p> <p>Debbie was speaking directly to teenage girls. Adolescents are still forming both their culinary and cultural tastes. They are forming their identities.</p> <p>For the Women’s Weekly, and for Debbie, cooking was deemed an essential attribute for women. Girls were seen to be “<a href="http://nla.gov.au/nla.news-page4818166">failures</a>” if they couldn’t at least “cook a baked dinner”, “make real coffee”, “grill a steak to perfection”, “scramble and fry eggs” and “make a salad (with dressing)”. </p> <p>In addition to teaching girls how to cook, Debbie also taught girls how to catch a husband and become a good wife, a reflection of cultural expectations for women at the time. </p> <p>Her <a href="http://nla.gov.au/nla.news-page4920059">macaroon trifle</a>, the Women’s Weekly said, was sure to place girls at the top of their male friends’ “matrimony prospect” list!</p> <h2>Food fads and fashions</h2> <p>Food fads usually reflect something important about the world around us. During global COVID lockdowns, we saw a rise in <a href="https://theconversation.com/the-historical-roots-of-your-lockdown-sourdough-obsession-137528">sourdough bread-making</a> as people embraced carbohydrate-driven nostalgia in the face of anxiety.</p> <p>A peek at Debbie’s culinary repertoire can reveal some of the cultural phenomena that impacted Australian teenagers in the 1950s and ‘60s. </p> <p>Debbie embraced teenage interest in rock'n'roll culture from the early 1960s, the pinnacle of which came at the height of Beatlemania. </p> <p>The Beatles toured Australia in June 1964. To help her teenage readers celebrate their visit, Debbie wrote an editorial on how to host a <a href="http://nla.gov.au/nla.news-article48077701">Beatles party</a>. </p> <p>She suggested the party host impress their friends by making “Beatle lollipops”, “Ringo Starrs” (decorated biscuits) and terrifying-looking “Beatle mop-heads” (cakes with chocolate hair).</p> <p><a href="http://nla.gov.au/nla.news-article55185376">A few months later</a>, she also shared recipes for “jam butties” (or sandwiches, apparently a “<a href="https://slate.com/culture/2013/03/the-beatles-and-the-mersey-beat-in-the-latest-blogging-the-beatles-how-the-beatles-popularized-the-sound-of-liverpool.html">Mersey</a> food with a Mersey name”) and a “Beatle burger”. </p> <p>We can also see the introduction of one of <a href="https://www.sbs.com.au/language/italian/en/article/spag-bol-how-australians-adopted-a-classic-italian-recipe-and-made-it-their-own/9ogvr96ea">Australia’s most beloved dishes</a> in Debbie’s recipes. </p> <p>In 1957, she showed her teen readers how to make a new dish – <a href="http://nla.gov.au/nla.news-article48076527">spaghetti bolognaise</a> – which had first appeared in the magazine <a href="http://nla.gov.au/nla.news-article46465023">five years prior</a>. </p> <p>Debbie was influencing the youth of Australia to enthusiastically adopt (and adapt) Italian-style cuisine. It stuck. While the recipe may have evolved, in 2012, Meat and Livestock Australia <a href="https://www.mla.com.au/globalassets/mla-corporate/marketing-beef-and-lamb/last-nights-dinner.pdf">reported</a> that 38% of Australian homes ate “spag bol” at least once a week.</p> <p>Our food influences today may come from social media, but we shouldn’t forget the impact early influencers such as Debbie had on young people in the past.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared in <a href="https://theconversation.com/tangy-apricot-bavarian-whip-fried-rice-medley-and-bombe-alaska-what-australias-first-food-influencer-had-us-cooking-199987" target="_blank" rel="noopener">The Conversation</a>.</em></p>

No, you shouldn’t wash raw chicken before cooking it. So why do people still do it?

<p>Food safety authorities and regulators <a href="https://foodsafety.asn.au/topic/tips-poultry/">around</a> <a href="https://www.cdc.gov/foodsafety/chicken.html#:%7E:text=after%20handling%20chicken.-,Do%20not%20wash%20raw%20chicken.,that%20previously%20held%20raw%20chicken.">the</a> <a href="https://www.food.gov.uk/safety-hygiene/cleaning">world</a> <a href="https://www.mpi.govt.nz/food-safety-home/preparing-and-storing-food-safely-at-home/clean-cook-chill/#:%7E:text=Don't%20wash%20raw%20chicken,food%20poisoning%20from%20campylobacter%20bacteria.">recommend</a> you don’t wash raw poultry before cooking. </p> <p>That’s because washing chicken can splash dangerous bacteria around the kitchen. It’s best just to thoroughly cook the chicken without washing it, so it is safe to eat.</p> <p>Despite this, chicken-washing remains common. A <a href="https://www.safefood.qld.gov.au/newsroom/does-raw-chicken-need-rinsing/">survey</a> by Australia’s Food Safety Information Council showed almost half of Australian home cooks washed whole chickens before cooking. Dutch research found <a href="https://www.foodsafetynews.com/2022/05/dutch-survey-finds-a-quarter-of-people-wash-chicken-despite-expert-advice/">25%</a> of consumers washed their chicken often or almost always.</p> <p>So why do people do it – and what does the research say about the risks of chicken-washing?</p> <h2>Chicken meat and germs</h2> <p>Incorrect cooking temperatures and cross-contamination between different foods are two of the most important factors linked to foodborne illness. </p> <p>This is particularly relevant to poultry meat. Two leading causes of foodborne illness are the bacteria <a href="https://www.cdc.gov/campylobacter/index.html">Campylobacter</a> and <a href="https://www.cdc.gov/foodsafety/communication/salmonella-food.html">Salmonella</a>, which are commonly found on raw poultry. </p> <p>In Australia, reported cases of Campylobacter and Salmonella have almost <a href="https://foodsafety.asn.au/topic/tips-poultry/">doubled</a>over the last two decades. </p> <p>Of the estimated 220,000 cases of Campylobacter infection each year, <a href="https://foodsafety.asn.au/topic/tips-poultry/">50,000</a> can be attributed either directly or indirectly to chicken meat.</p> <h2>Chicken-washing myths, busted</h2> <p>One <a href="https://doi.org/10.1016/j.foodcont.2020.107682">analysis</a> of consumer responses to an education campaign about the dangers of washing raw poultry shed light on why many people still wash raw chicken before cooking.</p> <p>Some believe there is a need to wash faeces and other matter off the chicken meat. In fact, modern processing techniques mean chicken carcasses do not need additional cleaning. </p> <p>Others believe washing with a slightly acidic solution (such as vinegar or lemon juice) will kill bacteria. </p> <p>On the contrary, <a href="https://doi.org/10.1016/j.foodcont.2018.06.034">research</a> has shown washing raw poultry in lemon juice or vinegar does not remove bacteria and can increase the cross-contamination risk.</p> <h2>Washing chicken splashes bacteria around</h2> <p>One of the more compelling arguments why washing raw poultry under a running tap is a risky activity comes from <a href="https://doi.org/10.1063/5.0083979">recent research</a> on water droplets ejected from the surface of washed chicken. </p> <p>The study clearly showed bacteria can be transferred from the surface of the chicken to surrounding surfaces via water droplets.</p> <p>Using high-speed imaging, the researchers found a higher tap height can increase splashing. </p> <p>Chicken meat is often soft and the water flow can create a divot in the surface. This leads to splashing that would not occur on a curved, hard surface. </p> <p>The researchers placed large agar plates next to the chicken surfaces to capture any water droplets. This allowed them to grow the bacteria that were transferred with the splashed water. </p> <p>They found the level of bacterial transmission increased with greater tap height and water flow rate. </p> <p>Aerated water (which is what you get when the tap is running very hard) also increased splashing and bacterial transmission. </p> <h2>What if I still really want to wash my chicken meat?</h2> <p>While washing raw poultry is not recommended, it appears some home cooks are reluctant to let go of this old habit. </p> <p>If you insist on washing chicken meat, consider doing so in a sink of water rather than under a running tap.</p> <p>Use a paper towel to mop up any liquids, dispose of the towel and clean up afterwards. </p> <p>This will help reduce the risk of cross-contamination and keep the kitchen safe. And please wash your hands after handling raw meat!</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/no-you-shouldnt-wash-raw-chicken-before-cooking-it-so-why-do-people-still-do-it-192723" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Are our phones really designed to slow down over time? Experts look at the evidence

<p>It’s usually around this time of year you hear people complain about their phones slowing down. Apple and Google release new versions of their operating systems (OS) and suddenly there’s a slew of people <a href="https://www.bbc.com/news/technology-51413724">claiming their old devices have started to lag</a> – conveniently just before Christmas. </p> <p>But do manufacturers really slow down our phones on purpose to nudge us towards shiny new ones, <a href="https://www.npr.org/2020/11/18/936268845/apple-agrees-to-pay-113-million-to-settle-batterygate-case-over-iphone-slowdowns">as has been claimed</a>? </p> <p>The answer to this, as usual, is complicated. Let’s take a look at the evidence.</p> <h2>The ol’ operating system shuffle</h2> <p>Every year, usually around <a href="https://infonewt.com/apple-release-patterns">May and June</a>, tech companies announce their new OS updates. The main news surrounding the releases is often <a href="https://www.macstories.net/stories/ios-and-ipados-15-the-macstories-overview/">new system features</a>such as <a href="https://support.apple.com/en-au/HT204380">Facetime</a> enhancements, improvements to <a href="https://www.theverge.com/2021/6/7/22522993/apple-siri-on-device-speech-recognition-no-internet-wwdc">voice assistants</a>, or a <a href="https://www.wired.com/2013/06/ios7-redesign/">fancier system design</a>.</p> <p>But did you know these features are optimised for the new hardware traditionally released during the summer, and the chips that come with it? </p> <p>As such, system updates have to be programmed to work towards two goals. The first is to support the new hardware and chip, which deliver the newest features. </p> <p>The second is to continue to work with existing hardware that won’t support the new features. And this means coding the OS so it’s not reliant on the new features having to work.</p> <p>This challenge exists for desktop OSs as well, as evidenced by the recent removal of old systems <a href="https://www.theverge.com/2021/6/29/22555371/microsoft-windows-11-cpu-support-hardware-requirements-tpm-response">from the Windows 11 compatibility list</a>. Microsoft decided coding around new features was an insurmountable challenge in some instances. </p> <h2>Hardships with hardware</h2> <p>So your old smartphone won’t support new features – fair enough. But why does it feel like the new OS update is making existing features slower? To understand this, you need to first understand some of the mechanics of chip design.</p> <p>Apple used to use other manufacturers’ chips for its devices, but for the past few years has made its own custom silicon. This is referred to as a “<a href="https://anysilicon.com/what-is-a-system-on-chip-soc/">system on a chip (SoC)</a>, as the entire system exists on a single chip designed and manufactured by Apple.</p> <p>But even if manufacturers design their own chips, it can be hard to predict what consumers will want in the future, and thus which upgrades will come with future iterations of a device. </p> <p>Manufacturers have to write OS updates to suit the latest hardware, so consumers who purchase it can take advantage of the latest features. In doing so, they must work around the fact that older hardware doesn’t have the same capacity. </p> <p>These workarounds mean older devices will run more slowly with the new OS installed, even for tasks the system had done for years. The latest OS is not written to make your old device slower, but because it’s written for the latest device, it can’t help but run more slowly on old hardware. </p> <p>Examples of this abound in the industry, <a href="https://arstechnica.com/gadgets/2020/09/ios-14-on-the-iphone-6s-and-se-performance-is-fine-other-stuff-is-not/">with many articles written</a> about a newly released OS version running slow on older devices until the manufacturer optimises it (if they ever do).</p> <p>You might be wondering: if a new OS will slow down old phones, why install the update at all? </p> <p>Well, it’s because people don’t like being told to stick with old features. Apple <a href="https://9to5mac.com/2021/06/07/apple-will-let-users-stay-on-ios-14-and-receive-security-updates-even-after-ios-15-is-released/">recently allowed</a> users of its latest devices to keep the old system, but this is unusual. There is usually a <a href="https://www.popsci.com/update-every-gadget/">push for users to install new OS versions</a>.</p> <h2>It’s all business</h2> <p>The truth is device manufacturers are in the business to make money. And this means being able to sell new devices. </p> <p>While there is often an <a href="https://theconversation.com/upgrade-rage-why-you-may-have-to-buy-a-new-device-whether-you-want-to-or-not-153105">implied expectation</a> from consumers that manufacturers will commit to maintaining old products, at the same time they need to write updates that will work for their latest hardware. </p> <p>Meanwhile, tech companies aren’t doing enough to educate users on how to adjust their settings to get the best out of their phones, or <a href="https://www.wired.com/story/remove-bloatware-phone/">how to manage software bloat</a> which might contribute to a phone slowing down. </p> <p>Compounding this are other factors such as network connection issues, like when the 3G mobile network was stopped.</p> <h2>Burden of proof</h2> <p>There’s something else to consider, too. If an OS update was designed to intentionally slow down a phone over time, this would be very difficult to prove. </p> <p>The system codes are "closed source”, so experts can’t look into them. The best we can do is run timers on different processes and see if they are slowing down over time.</p> <p>But even if they are, is it because of a system update that can’t be supported by old hardware, or is it malicious conduct from the manufacturer? Could the code be written to force the device to sleep for half a second, every ten seconds, with a sleep command? </p> <p>It’s hard to say for sure, although our personal opinion is this is highly unlikely.</p> <h2>Choose not to play</h2> <p>Ultimately, the issue comes down to how device manufacturers sell their products. </p> <p>The best option for their bottom line is to deliver OS updates and features that work with the latest hardware, even if this leaves old devices behind. The evidence suggests manufacturers are not intentionally slowing phones down, but are prioritising the latest release so you’ll buy it. </p> <p>In the meantime, if your slow device is getting you down, the best option is to resist the urge to upgrade. You might get prompts directing you to install the latest OS version (and the frequency of these will depend on the company) but you can ignore them. </p> <p>There may be auto-updates which you can’t avoid, but in most cases these are for security purposes and don’t include major changes or new features. It’s only once these security updates stop coming that you should upgrade.</p> <p>Until then, a phone running on its original OS should, in theory, run well for a long time.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/are-our-phones-really-designed-to-slow-down-over-time-experts-look-at-the-evidence-170962" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Do you use predictive text? Chances are it’s not saving you time – and could even be slowing you down

<p>Typing is one of the most common things we do on our mobile phones. A recent survey suggests that millenials spend <a href="https://www.provisionliving.com/blog/smartphone-screen-time-baby-boomers-and-millennials/">48 minutes</a> each day texting, while boomers spend 30 minutes.</p> <p>Since the advent of mobile phones, the way we text has changed. We’ve seen the introduction of autocorrect, which corrects errors as we type, and word prediction (often called predictive text), which predicts the next word we want to type and allows us to select it above the keyboard.</p> <p>Functions such as autocorrect and predictive text are designed to make typing faster and more efficient. But research shows this isn’t necessarily true of predictive text.</p> <p>A <a href="https://dl.acm.org/doi/10.1145/2858036.2858305">study</a> published in 2016 found predictive text wasn’t associated with any overall improvement in typing speed. But this study only had 17 participants – and all used the same type of mobile device.</p> <p>In 2019, my colleagues and I published <a href="https://doi.org/10.1145/3338286.3340120">a study</a> in which we looked at mobile typing data from more than 37,000 volunteers, all using their own mobile phones. Participants were asked to copy sentences as quickly and accurately as possible.</p> <p>Participants who used predictive text typed an average of 33 words per minute. This was slower than those who didn’t use an intelligent text entry method (35 words per minute) and significantly slower than participants who used autocorrect (43 words per minute).</p> <h2>Breaking it down</h2> <p>It’s interesting to consider the poor correlation between predictive text and typing performance. The idea seems to make sense: if the system can predict your intended word before you type it, this should save you time. </p> <p>In my most <a href="https://doi.org/10.1145/3411764.3445566">recent study</a> on this topic, a colleague and I explored the conditions that determine whether predictive text is effective. We combined some of these conditions, or parameters, to simulate a large number of different scenarios and therefore determine when predictive text is effective – and when it’s not.</p> <p>We built a couple of fundamental parameters associated with predictive text performance into our simulation. The first is the average time it takes a user to hit a key on the keyboard (essentially a measure of their typing speed). We estimated this at 0.26 seconds, based on <a href="https://dl.acm.org/doi/10.1145/2470654.2466180">earlier research</a>.</p> <p>The second fundamental parameter is the average time it takes a user to look at a predictive text suggestion and select it. We fixed this at 0.45 seconds, again based on <a href="https://dl.acm.org/doi/10.1145/1240624.1240723">existing data</a>.</p> <p>Beyond these, there’s a set of parameters which are less clear. These reflect the way the user engages with predictive text – or their strategies, if you like. In our research, we looked at how different approaches to two of these strategies influence the usefulness of predictive text.</p> <p>The first is minimum word length. This means the user will tend to only look at predictions for words beyond a certain length. You might only look at predictions if you’re typing longer words, beyond, say, six letters – because these words require more effort to spell and type out. The horizontal axis in the visualisation below shows the effect of varying the minimum length of a word before the user seeks a word prediction, from two letters to ten.</p> <p>The second strategy, “type-then-look”, governs how many letters the user will type before looking at word predictions. You might only look at the suggestions after typing the first three letters of a word, for example. The intuition here is that the more letters you type, the more likely the prediction will be correct. The vertical axis shows the effect of the user varying the type-then-look strategy from looking at word predictions even before typing (zero) to looking at predictions after one letter, two letters, and so on.</p> <p>A final latent strategy, perseverance, captures how long the user will type and check word predictions for before giving up and just typing out the word in full. While it would have been insightful to see how variation in perseverance affects the speed of typing with predictive text, even with a computer model, there were limitations to the amount of changeable data points we could include.</p> <p>So we fixed perseverance at five, meaning if there are no suitable suggestions after the user has typed five letters, they will complete the word without consulting predictive text further. Although we don’t have data on the average perseverance, this seems like a reasonable estimate.</p> <h2>What did we find?</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/12/graph-text.jpg" alt="" />Above the dashed line there’s an increase in net entry rate while below it, predictive text slows the user down. The deep red shows when predictive text is most effective; an improvement of two words per minute compared to not using predictive text. The blue is when it’s least effective. Under certain conditions in our simulation, predictive text could slow a user down by as much as eight words per minute. </p> <p>The blue circle shows the optimal operating point, where you get the best results from predictive text. This occurs when word predictions are only sought for words with at least six letters and the user looks at a word prediction after typing three letters.</p> <p>So, for the average user, predictive text is unlikely to improve performance. And even when it does, it doesn’t seem to save much time. The potential gain of a couple of words per minute is much smaller than the potential time lost.</p> <p>It would be interesting to study long-term predictive text use and look at users’ strategies to verify that our assumptions from the model hold in practice. But our simulation reinforces the findings of previous human research: predictive text probably isn’t saving you time – and could be slowing you down.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/do-you-use-predictive-text-chances-are-its-not-saving-you-time-and-could-even-be-slowing-you-down-170163" target="_blank" rel="noopener">The Conversation</a>. </em></p>
