Why Greg Lynn could walk free from prison

<p>Greg Lynn has applied to be freed from jail until his sentencing hearing over the murder of Carol Clay. </p> <p>The former Jetstar pilot, who was found guilty of murdering the 73-year-old while she was camping with her secret partner Russell Hill in March 2020, is appealing the guilty verdict which the jury came to after a weeks-long trial in June. </p> <p>The 57-year old appeared in the Supreme Court of Victoria on Friday where Justice Michael Croucher heard the convicted killer had been the victim of prison attacks during his six-week trial. </p> <p>The court heard Lynn's barrister Dermot Dann KC is in the process of compiling submissions calling on Justice Croucher to hold of on sentencing his client until an appeal over his conviction can be heard by the Court of Appeal. </p> <p>If granted, the "stay" of sentence could allow Lynn to apply for bail while his appeal goes through the court. </p> <p>The court also heard that Lynn had been placed in isolation within the Metropolitan Remand Prison for his own safety since the guilty verdict was read, but now fears he will be targeted by inmates at whatever prison he ultimately ends up in. </p> <p>Mr Dann said a successful appeal could result in Lynn being set free altogether without the possibility of a re-trial, due to doubts over whether he could obtain a fair trial because of the significant publicity surrounding the case and the murder conviction. </p> <p>"The chances of a fair re-trial are non-existent," Mr Dann said. </p> <p>The experienced barrister said any potential jurors would have been "polluted or poisoned" by the "inadmissible evidence" that has "flooded" news sites since the guilty verdict was delivered.  </p> <p>The court heard Mr Dann believed his client had multiple reasons to push for an appeal over his verdict, including the "unfair" way in which he claimed the Office of Public Prosecutions carried out the trial. </p> <p>Mr Dann reiterated to the court that his client has always maintained his innocence, saying, "He maintains that he's never killed any person at any time, at any place, anywhere, ever."</p> <div data-component="EmphasisedText"> <p>"The long-term future of that guilty verdict must be seen as being in grave doubt."</p> <p><span style="font-size: 16px; font-family: abcsans, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif;">The case was adjourned until a pre-sentence hearing on September 12th. </span></p> <p><em><span style="font-family: abcsans, -apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Helvetica Neue, Arial, sans-serif;">Image credits: Facebook</span></em></p> </div>

Walking or running: for the same distance, which consumes more energy?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/clement-lemineur-1529211">Clément Lemineur</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>; <a href="https://theconversation.com/profiles/clement-naveilhan-1495411">Clément Naveilhan</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>, and <a href="https://theconversation.com/profiles/francois-dernoncourt-1495410">François Dernoncourt</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a></em></p> <p>It’s Monday morning, the alarm goes off and it’s already 7:30 a.m. – and you’re 30 minutes late. Normally you need 45 minutes to walk the 3 kilometres to work, but this morning you’ll be running for 20 minutes. Yes, but by lunchtime you’re feeling more tired and you have the impression that you’ve expended more energy than usual on the trip. Yet you’ve covered the same distance as on the other days. How can this be?</p> <p>The calorie expenditure associated with any activity is called the “metabolic cost”, and corresponds to the energy consumed by our organs to cover a given distance. This metabolic cost can be determined by analysing the oxygen our bodies consume and the carbon dioxide they produce, we can estimate the amount of energy expended, and thus the metabolic cost. It was using this method that <a href="https://pubmed.ncbi.nlm.nih.gov/692303/">researchers had already answered our question back in the 1970s</a>.</p> <p>Perhaps not surprisingly, running consumes more energy than walking for the same distance covered. But why?</p> <h2>Energy lost when running</h2> <p>Imagine you’re watching someone running. Now look closely at the vertical movement (up and down) of their pelvis and head. As you can see from the diagram below, when we run, the distance that our body moves up and down is greater than when we walk. To produce this vertical movement, the muscles of the lower limbs have to generate more force, and that consumes more energy, yet doesn’t bring us any closer to our destination. So when running, part of the energy expended is used to move our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/16029949/">upward rather than forward</a>. The energy needed to cover those 3 km is therefore higher for running than for walking.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=287&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=287&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=287&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=361&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=361&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=361&amp;fit=crop&amp;dpr=3 2262w" alt="Illustration of the oscillations of running and walking" /></a><figcaption><span class="caption">Running involves much greater vertical oscillation of the centre of mass than walking. This is the main reason why running consumes more energy than walking for the same distance covered.</span> <span class="attribution"><span class="source">François Dernoncourt</span>, <span class="license">Fourni par l'auteur</span></span></figcaption></figure> <p>This difference between walking and running is not confined to what happens during the activity itself. In fact, each physical exercise causes a delayed expenditure of energy, which is added to the expenditure during the activity.</p> <p>Taking this into account, it’s once again running that uses more energy than walking. Immediately after running your 3 km, the increased energy consumption (compared with resting) lasts for several minutes, mainly because of the increase in body temperature and the replenishment of energy reserves. This additional expenditure after running is <a href="https://pubmed.ncbi.nlm.nih.gov/22446673/">more than twice that observed after walking</a>, due to the difference in intensity between the two exercises.</p> <h2>It all depends on speed</h2> <p>Running therefore involves a higher calorie expenditure than walking for the same distance covered. But this is on condition that the walking speed considered is “normal” (around 5 km/h). So, if we walk very slowly, it will take us so long to cover the 3 km that the calorie expenditure will be greater in the end. This is because the body expends a certain amount of energy per unit of time no matter what, regardless of the activity performed (known as the “basal metabolic rate”).</p> <p>The same applies if the walking speed is very fast (<a href="https://pubmed.ncbi.nlm.nih.gov/29925582/">more than 8 km/h</a>): running is more energy-efficient. Here, the coordination required to walk at such a speed means that we need to activate our muscles more, without being able to take advantage of the elasticity of our tendons, as is the case with running.</p> <p>Moreover, we have a very precise intuitive perception of the energy efficiency of a particular style of movement. If we’re on a treadmill whose speed gradually increases, the point at which we spontaneously switch from walking to running coincides with the <a href="https://www.sciencedirect.com/science/article/pii/S096663622100120X">moment when it would become more energy-consuming to walk than to run</a>.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=395&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=395&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=395&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=497&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=497&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=497&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Modelling of metabolic cost (kilocalories expended per kilogram per kilometre covered) as a function of speed (kilometres per hour) for walking and running.

Walking can prevent low back pain, a new study shows

If you do, you’re not alone. Roughly <a href="https://pubmed.ncbi.nlm.nih.gov/31208917/">70% of people</a> who recover from an episode of low back pain will experience a new episode in the following year.</p> <p>The recurrent nature of low back pain is a major contributor to the <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00098-X/fulltext">enormous burden</a> low back pain places on individuals and the health-care system.</p> <p>In our new study, published today in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00755-4/fulltext">The Lancet</a>, we found that a program combining walking and education can effectively reduce the recurrence of low back pain.</p> <h2>The WalkBack trial</h2> <p>We randomly assigned 701 adults who had recently recovered from an episode of low back pain to receive an individualised walking program and education (intervention), or to a no treatment group (control).</p> <p>Participants in the intervention group were guided by physiotherapists across six sessions, over a six-month period. In the first, third and fifth sessions, the physiotherapist helped each participant to develop a personalised and progressive walking program that was realistic and tailored to their specific needs and preferences.</p> <p>The remaining sessions were short check-ins (typically less than 15 minutes) to monitor progress and troubleshoot any potential barriers to engagement with the walking program. Due to the COVID pandemic, most participants received the entire intervention via telehealth, using video consultations and phone calls.</p> <p>The program was designed to be manageable, with a target of five walks per week of roughly 30 minutes daily by the end of the six-month program. Participants were also encouraged to continue walking independently after the program.</p> <p>Importantly, the walking program was combined with education provided by the physiotherapists during the six sessions. This education aimed to give people a better understanding of pain, reduce fear associated with exercise and movement, and give people the confidence to self-manage any minor recurrences if they occurred.</p> <p>People in the control group received no preventative treatment or education. This reflects what <a href="https://www.sciencedirect.com/science/article/abs/pii/S2468781222001308?via%3Dihub">typically occurs</a> after people recover from an episode of low back pain and are discharged from care.</p> <h2>What the results showed</h2> <p>We monitored the participants monthly from the time they were enrolled in the study, for up to three years, to collect information about any new recurrences of low back pain they may have experienced. We also asked participants to report on any costs related to their back pain, including time off work and the use of health-care services.</p> <p>The intervention reduced the risk of a recurrence of low back pain that limited daily activity by 28%, while the recurrence of low back pain leading participants to seek care from a health professional decreased by 43%.</p> <p>Participants who received the intervention had a longer average period before they had a recurrence, with a median of 208 days pain-free, compared to 112 days in the control group.</p> <p>Overall, we also found this intervention to be cost-effective. The biggest savings came from less work absenteeism and less health service use (such as physiotherapy and massage) among the intervention group.</p> <p>This trial, like all studies, had some limitations to consider. Although we tried to recruit a wide sample, we found that most participants were female, aged between 43 and 66, and were generally well educated. This may limit the extent to which we can generalise our findings.</p> <p>Also, in this trial, we used physiotherapists who were up-skilled in health coaching. So we don’t know whether the intervention would achieve the same impact if it were to be delivered by other clinicians.</p> <h2>Walking has multiple benefits</h2> <p>We’ve all heard the saying that “prevention is better than a cure” – and it’s true. But this approach has been largely neglected when it comes to low back pain. Almost all <a href="https://www.sciencedirect.com/science/article/pii/S0140673618304896?via%3Dihub">previous studies</a> have focused on treating episodes of pain, not preventing future back pain.</p> <p>A limited number of <a href="https://pubmed.ncbi.nlm.nih.gov/26752509/">small studies</a> have shown that exercise and education can help prevent low back pain. However, most of these studies focused on exercises that are not accessible to everyone due to factors such as high cost, complexity, and the need for supervision from health-care or fitness professionals.</p> <p>On the other hand, walking is a free, accessible way to exercise, including for people in rural and remote areas with limited access to health care.</p> <p>Walking also delivers many other <a href="https://www.vichealth.vic.gov.au/sites/default/files/VH_Benefits-of-Walking-Summary2020.pdf">health benefits</a>, including better heart health, improved mood and sleep quality, and reduced risk of several chronic diseases.</p> <p>While walking is not everyone’s favourite form of exercise, the intervention was well-received by most people in our study. Participants <a href="https://pubmed.ncbi.nlm.nih.gov/37271689/">reported</a> that the additional general health benefits contributed to their ongoing motivation to continue the walking program independently.</p> <h2>Why is walking helpful for low back pain?</h2> <p>We don’t know exactly why walking is effective for preventing back pain, but <a href="https://www.e-jer.org/journal/view.php?number=2013600295">possible reasons</a> could include the combination of gentle movements, loading and strengthening of the spinal structures and muscles. It also could be related to relaxation and stress relief, and the release of “feel-good” endorphins, which <a href="https://my.clevelandclinic.org/health/body/23040-endorphins">block pain signals</a> between your body and brain – essentially turning down the dial on pain.</p> <p>It’s possible that other accessible and low-cost forms of exercise, such as swimming, may also be effective in preventing back pain, but surprisingly, <a href="https://pubmed.ncbi.nlm.nih.gov/34783263/">no studies</a> have investigated this.</p> <p>Preventing low back pain is not easy. But these findings give us hope that we are getting closer to a solution, one step at a time.<!-- Below is The Conversation's page counter tag.

To-do list got you down? Understanding the psychology of goals can help tick things off – and keep you on track

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/kim-m-caudwell-1258935">Kim M Caudwell</a>, <a href="https://theconversation.com/institutions/charles-darwin-university-1066">Charles Darwin University</a></em></p> <p>It feels like we are living in busy times.</p> <p>According to the <a href="https://www.oecdbetterlifeindex.org/topics/work-life-balance/">OECD Better Life Index</a>, 12.5% of Australians report working at least 50 hours a week, higher than the OECD average. Many Australians are also <a href="https://www.abc.net.au/news/2023-08-03/multiple-job-holders-hit-record-high-abs/102679190">working more than one job to buffer against cost-of-living pressures</a>.</p> <p>Psychology has long been interested in our goals – our mental representations of desirable outcomes. Much of this research is on how we form, pursue and attain goals, plus how goals make us feel. Across studies, we see a consistent pattern of <a href="https://link.springer.com/article/10.1007/s10902-013-9493-0#Sec34">successful goal pursuit and wellbeing</a>. So, having time to work toward our goals is important.</p> <p>With this in mind, what is the best way to get things done – and how can we get better at achieving our goals, especially when we feel time poor?</p> <h2>Make a list</h2> <p>Most of us approach multiple goals with the age-old “to-do” list. First, you write down everything you need to do. Then you “check” or tick things off as you do them.</p> <p>One reason to-do lists are useful is because we are more likely to remember things we haven’t completed, rather than things we have. This is known as the <a href="https://www.youtube.com/watch?v=E-F1U4bV2m8">Zeigarnik effect</a>.</p> <p>While to-do lists are easy to write, they don’t always work. There are however <a href="https://hbr.org/2021/01/i-tried-4-to-do-list-methods-heres-what-worked">various approaches for to-do lists</a> that may improve their effectiveness.</p> <p>Another thing to consider is the wide range of apps, tools and platforms that can make tasks more fun and outsource mental load. Adding elements of game play like point scoring or competition – called “<a href="https://theconversation.com/how-gamification-could-revolutionise-creative-thinking-in-the-workplace-122852">gamification</a>” – can <a href="https://www.sciencedirect.com/science/article/pii/S0747563221002867">help people work toward goals in educational and work settings</a>. Similarly, app-based reminders can help people reach <a href="https://doi.org/10.1177/2047487320905717">physical rehabilitation goals and form good exercise habits</a>.</p> <h2>Finding your why</h2> <p>Researchers have focused a lot on the psychology of <em>why</em> people pursue goals – and how this affects their approach to tasks.</p> <p>For example, some people want to complete a university degree because they want to get a job. Others may be more interested in developing skills or knowledge. In both cases, there is a desired outcome – albeit with differing reasons.</p> <p>Our goals can be differentiated by who or what is driving them. Goals that feel like our own, and for which we experience a sense of intrinsic motivation, are known as “self-concordant”. These goals represent enduring personal interests, are aligned with values and are positively <a href="https://link.springer.com/article/10.1007/s12144-020-01156-7">linked to wellbeing</a>.</p> <p><a href="https://link.springer.com/article/10.1007/s10648-006-9012-5">Goal orientation theory</a> offers a similar perspective. Using the same example, you may study so you score well on a test (a performance goal) or because you want to be sure you develop your knowledge (a mastery goal). Mastery goals tend to lead to <a href="https://link.springer.com/article/10.1007/s10869-010-9201-6">better results and self-regulation</a>.</p> <h2>Juggling goals – 4 to-do tips</h2> <p>So, what happens when we have multiple – perhaps even competing – goals, or goals that aren’t so enjoyable? We might want to finish writing a report or assignment, then read a few chapters of a textbook – but also go to the gym and binge a few episodes of our favourite TV show.</p> <p>In such scenarios, psychological science offers some insights into how we might stay task-focused, and on track to tick more items off our to-do list.</p> <p><strong>1. Beware the <a href="https://www.pwc.pl/en/articles/planning-fallacy-part-I-cognitive-traps.html">planning fallacy</a>.</strong> This happens when we underestimate the amount of resources (such as time) it will take to reach a goal. As writer and religious thinker William Penn put it: “Time is what we want most, but what we use worst”. Think through the all the steps and time required to complete your goal.</p> <p><strong>2. Monitor your progress.</strong> <a href="https://eprints.whiterose.ac.uk/91437/8/3_PDFsam_Does%20monitoring%20goal.pdf">Incorporating goal monitoring</a> into an activity can boost progress. And reviewing your estimations and expectations against your actual times and achievements can be used to calculate a “<a href="https://www.indeed.com/career-advice/career-development/estimating-time-for-tasks">fudge ratio</a>” to aid future planning. For instance, you could multiply your expected time on tasks by 1.5 to help buffer against the planning fallacy.</p> <p><strong>3. Focus on mastery.</strong> Self-concordant goals and tasks feel easier, and their underlying tasks may be <a href="https://journals.sagepub.com/doi/full/10.1177/0146167215575730">less subject to forgetting</a>. Tedious but necessary goals (such as doing the dishes or filling out forms) are less intrinsically motivating. This means <a href="https://www.emerald.com/insight/content/doi/10.1108/EBHRM-04-2014-0013/full/html#idm45933122746592">planning, reminders and support become more important to goal progress</a>.</p> <p><strong>4. Plan for derailments.</strong> People vary in their ability to plan and might forget to take a goal-directed action at an appropriate time (this could be one reason the <a href="https://www.sbs.com.au/news/article/the-streaming-services-winning-the-battle-for-attention-and-the-feature-australians-want/9crrpafgd">average Australian streams 27 hours of video each week</a>). <a href="https://www.tandfonline.com/doi/full/10.1080/10463283.2024.2334563">Implementation intentions</a> bring our attention back toward our goals by linking them to an environmental marker. These simple “if-then” plans are shown to <a href="https://cancercontrol.cancer.gov/brp/research/constructs/implementation-intentions#:%7E:text=Implementation%20intentions%20are%20formed%20for,might%20otherwise%20undermine%20goal%20striving.">help overcome issues with self-regulation</a>. Such a statement might be “if I see the ‘next episode’ icon appear, I will get up and turn off the TV so I can read a chapter of my textbook”.</p> <p>With time being frustratingly finite, it is inevitable we will run out of time to do all of the things on our to-do list. Finding an approach that works for us will take time and effort. But it’s probably a worthy goal in itself.<!-- Below is The Conversation's page counter tag.

How tracking menopause symptoms can give women more control over their health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/deborah-lancastle-1452267">Deborah Lancastle</a>, <em><a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a></em></p> <p>Menopause can cause more symptoms than hot flushes alone. And some of your symptoms and reactions might be due to the menopause, even if you are still having periods. Research shows that keeping track of those symptoms can help to alleviate them.</p> <p>People sometimes talk about the menopause as though it were a single event that happens when you are in your early 50s, which is <a href="https://www.mayoclinic.org/diseases-conditions/menopause/symptoms-causes/syc-20353397#:%7E:text=Menopause%20is%20the%20time%20that,is%20a%20natural%20biological%20process.">the average time</a> to have your last period. But the menopause generally stretches between the ages of 45 and 55. And some women will experience an earlier “medical” menopause because of surgery to remove the womb or ovaries.</p> <p>The menopause often happens at one of the busiest times of life. You might have teenagers at home or be supporting grown-up children, have elderly parents, be employed and have a great social life. If you feel exhausted, hot and bothered, irritable and can’t sleep well, you might be tempted to think that it is because you never get a minute’s peace. But that is why monitoring symptoms is important.</p> <p><a href="https://journals.lww.com/menopausejournal/Abstract/2023/03000/Symptom_monitoring_improves_physical_and_emotional.7.aspx">My team recently tested</a> the effects of tracking symptoms and emotions during the menopause. We asked women to rate 30 physical and 20 emotional symptoms of the menopause.</p> <p>The physical and psychological symptoms included poor concentration, problems with digesting food, stress and itchy skin, as well as the obvious symptoms like hot flushes and night sweats. Women tracked positive emotions like happiness and contentment, and negative emotions like feeling sad, isolated and angry.</p> <p>There were two groups of women in this study. One group recorded their symptoms and emotions every day for two weeks. The other group recorded their symptoms and emotions once at the beginning of the fortnight and once at the end.</p> <p>The results showed that the women who monitored their symptoms and emotions every day reported much lower negative emotions, physical symptoms and loneliness at the end of two weeks than at the beginning, compared to the other group.</p> <p>As well as this, although the loneliness scores of the group who monitored every day were lower than the other group, women in both groups said that being in the study and thinking about symptoms helped them feel less lonely. Simply knowing that other women were having similar experiences seemed to help.</p> <p>One participant said: “I feel more normal that other women are doing the same survey and are probably experiencing similar issues, especially the emotional and mental ones.”</p> <h2>Why does monitoring symptoms help?</h2> <p>One reason why tracking might help is that rating symptoms can help you notice changes and patterns in how you feel. This could encourage you to seek help.</p> <p>Another reason is that noticing changes in symptoms might help you link the change to what you have been doing. For example, looking at whether symptoms spike after eating certain foods or are better after exercise. This could mean that you change your behaviour in ways that improve your symptoms.</p> <p>Many menopause symptoms are known as “non-specific” symptoms. This is because they can also be symptoms of mental health, thyroid or heart problems. It is important not to think your symptoms are “just” the menopause. You should always speak to your doctor if you are worried about your health.</p> <p>Another good thing about monitoring symptoms is that you can take information about how often you experience symptoms and how bad they are to your GP appointment. This can help the doctor decide what might be the problem.</p> <p>Websites such as <a href="https://healthandher.com">Health and Her</a> and <a href="https://www.balance-menopause.com">Balance</a> offer symptom monitoring tools that can help you track what is happening to your physical and emotional health. There are several apps you can use on your phone, too. Or you might prefer to note symptoms and how bad they are in a notebook every day.<!-- Below is The Conversation's page counter tag.

Do parolees really ‘walk free’? Busting common myths about parole

Here’s what the evidence says about three of the most common misconceptions.</p> <h2>Myth 1: people on parole walk free</h2> <p>Parole is the conditional release of an incarcerated person (parolee) by a parole board authority, after they have served their non-parole period (minimum sentence) in jail. This isn’t always reflected in headlines.</p> <p><a href="https://www.9news.com.au/national/snowtown-murders-bodies-in-barrels-murders-mark-haydon-release-south-australia/f4b62a72-ec3d-4238-94d2-64697fbcdef3">Some coverage</a> suggests people on parole are released early and “walk free” without conditions. This is not true.</p> <p>According to the <a href="https://www.adultparoleboard.vic.gov.au/what-parole/purpose-and-benefits">Adult Parole Board of Victoria</a>: "Parole provides incarcerated people with a structured, supported and supervised transition so that they can adjust from prison back into the community, rather than returning straight to the community at the end of their sentence without supervision or support."</p> <p>Parole comes with strict conditions and requirements, such as curfews, drug and alcohol testing, electronic monitoring, program participation, to name a few.</p> <p>People with experience of parole highlight its punitivism and continued extension of surveillance.</p> <h2>Myth 2: most parolees reoffend</h2> <p>Another myth is that the likelihood all parolees reoffend is high. Research over a number of years has consistently found parole reduces reoffending.</p> <p>For example, <a href="https://journals.sagepub.com/doi/abs/10.1177/0004865815585393?journalCode=anja">a 2016 study in New South Wales</a> found at the 12 month mark, a group of parolees reoffended 22% less than an unsupervised cohort.</p> <p>A <a href="https://www.bocsar.nsw.gov.au/Publications/CJB/2022-Report-Effect-of-parole-supervision-on-recidivism-CJB245.pdf">2022 study</a> by the NSW Bureau of Crime Statistics and Research found parole was especially successful in reducing serious recidivism rates among incarcerated people considered to be at a high risk of reoffending.</p> <p>More recently in Victoria, <a href="https://www.adultparoleboard.vic.gov.au/system/files/inline-files/Adult%20Parole%20Board%20Annual%20Report%202022-23_0.pdf">the Adult Parole Board</a> found over 2022–23, no parolees were convicted of committing serious offences while on parole.</p> <p>In contrast, unstructured and unconditional release increases the risk of returning to prison.</p> <h2>Myth 3: parole is easy to get</h2> <p>While the number of parolees reoffending has dropped, so too has the total number of people who are exiting prison on parole.</p> <p>Over a decade ago, Victoria underwent significant parole reforms, largely prompted by high-profile incidents and campaigns. In just five years following Jill Meagher’s tragic death in 2012, the Victorian government passed <a href="https://www.tandfonline.com/doi/full/10.1080/10345329.2018.1556285">13 laws reshaping parole</a>.</p> <p>The result is the number of people on parole in Victoria has halved since 2012, despite incarceration numbers remaining steady.</p> <p><iframe id="maNRy" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/maNRy/" width="100%" height="400px" frameborder="0"></iframe></p> <p>These reforms have made it more difficult for people convicted of serious offences to get parole, as well as preventing individuals or specific groups from being eligible for parole (such as police killers, <a href="https://theconversation.com/no-body-no-parole-laws-could-be-disastrous-for-the-wrongfully-convicted-191083">“no body, no parole” prisoners</a>, and certain high-profile murderers).</p> <p>Similar laws can be found in other states. For example, no body, no parole was introduced in all other Australian states and territories, except for Tasmania and the Australian Capital Territory.</p> <p>As a consequence, more people are being released at the end of their full sentence. This can be detrimental not only for the incarcerated person but the wider community, because they are not receiving the reintegration support parole provides.</p> <p>Aside from restricted access due to political intervention, parole is facing a new crisis, which has nothing to do with eligibility or suitability.</p> <p>Last year, 40% of Victorian parole applications were denied, often due to reasons <a href="https://www.adultparoleboard.vic.gov.au/system/files/inline-files/Adult%20Parole%20Board%20Annual%20Report%202022-23_0.pdf">unrelated to suitability</a>.</p> <p>Housing scarcity played a significant role, with 59% of rejections (or 235 applications) citing a lack of suitable accommodation as one of the reasons parole was denied. This is playing out <a href="https://www.abc.net.au/news/2023-08-11/women-on-bail-parole-increased-risk-of-homelessness-qld/102717002">across the country</a>.</p> <p>Parole is vulnerable to community and media hype, and political knee-jerk reactions in response to high profile incidents involving a person on parole. Because of the actions of a few, parole as a process has been restricted for many.</p> <p>While the wider community are active in advocacy efforts to restrict parole from certain people or groups (for example, this petition for <a href="https://www.change.org/p/lyns-law-no-body-no-parole">Lyn’s Law in NSW</a>), public efforts to restrict parole seem at odds with its purposes.</p> <p>Despite this, research suggests when the public are educated about the purposes and intent of parole, they are more likely to be <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3125829">supportive of it</a>.</p> <p>The susceptibility of parole to media and community influence results in frequent, impactful changes affecting individuals inside and outside prisons. Headlines such as “walking free” have the potential to mislead the public on the purpose and structure of parole. Coverage should portray parole beyond mere early termination of a sentence by accurately reflecting its purpose and impact.<!-- Below is The Conversation's page counter tag.

Only walking for exercise? Here’s how to get the most out of it

<p><em><a href="https://theconversation.com/profiles/ken-nosaka-169021">Ken Nosaka</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>We’re living longer than in previous generations, with <a href="https://www.aihw.gov.au/reports/older-people/older-australians/contents/demographic-profile">one in eight</a> elderly Australians now aged over 85. But the current <a href="https://pubmed.ncbi.nlm.nih.gov/26561272/">gap</a> between life expectancy (“lifespan”) and health-adjusted life expectancy (“healthspan”) is about ten years. This means many of us live with significant health problems in our later years.</p> <p>To increase our healthspan, we need planned, structured and regular physical activity (or exercise). The <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">World Health Organization recommends</a> 150–300 minutes of moderate-intensity exercise – such as brisk walking, cycling and swimming – per week and muscle strengthening twice a week.</p> <p>Yet few of us meet these recommendations. <a href="https://doi.org/10.1186/s12966-019-0797-2">Only 10%</a> meet the strength-training recommendations. <a href="https://pubmed.ncbi.nlm.nih.gov/32488898/">Lack of time</a> is one of the most common reasons.</p> <p>Walking is cost-effective, doesn’t require any special equipment or training, and can be done with small pockets of time. <a href="https://link.springer.com/epdf/10.1007/s00421-024-05453-y?sharing_token=1vDsDJTN5WzPxi5YmSEkOfe4RwlQNchNByi7wbcMAY5hnPeFvF3FY4v2z1P9M2M0oiR78kXv1Yzj0ODMgckqhKOGHUABEd9UOPOfV5kPAj1jf1IYMIYkdIBv-DUEcKCOiDdNyj6MFypeDhSyeYQrWu_bvlAYtPUmOSaldFpmycA%3D">Our preliminary research</a>, published this week, shows there are ways to incorporate strength-training components into walking to improve your muscle strength and balance.</p> <h2>Why walking isn’t usually enough</h2> <p>Regular walking <a href="http://theconversation.com/health-check-in-terms-of-exercise-is-walking-enough-78604">does not appear</a> to work as muscle-strengthening exercise.</p> <p>In contrast, exercises consisting of “eccentric” or muscle-lengthening contractions <a href="http://theconversation.com/its-ok-to-aim%20lower-with-your-new-years-exercise-resolutions-a-few-minutes-a-day-can-improve-your-muscle-strength-193713">improve</a> muscle strength, <a href="https://pubmed.ncbi.nlm.nih.gov/31130877/">prevent muscle wasting</a> and improve other functions such as balance and flexibility.</p> <p>Typical eccentric contractions are seen, for example, when we sit on a chair slowly.

It consisted of four weeks of normal walking followed by eight weeks of eccentric walking.</p> <p>The number of eccentric steps in the eccentric walking period gradually increased over eight weeks from 100 to 1,000 steps (including lunges, downhill and downstairs steps). Participants took a total of 3,900 eccentric steps over the eight-week eccentric walking period while the total number of steps was the same as the previous four weeks.</p> <p>We measured the thickness of the participants’ front thigh muscles, muscle strength in their knee, their balance and endurance, including how many times they could go from a sitting position to standing in 30 seconds without using their arms.

And we asked participants to complete a questionnaire relating to their activities of daily living, such as dressing and moving around at home.</p> <p>Finally, we tested participants’ blood sugar, cholesterol levels and complement component 1q (C1q) concentrations, a potential <a href="https://faseb.onlinelibrary.wiley.com/doi/abs/10.1096/fj.14-262154">marker of sarcopenia</a> (muscle wasting with ageing).</p> <h2>What did we find?</h2> <p>We found no significant changes in any of the outcomes in the first four weeks when participants walked conventionally.</p> <p>From week four to 12, we found significant improvements in muscle strength (19%), chair-stand ability (24%), balance (45%) and a cognitive function test (21%).</p> <p>Serum C1q concentration decreased by 10% after the eccentric walking intervention, indicating participants’ muscles were effectively stimulated.</p> <p>The sample size of the study was small, so we need larger and more comprehensive studies to verify our findings and investigate whether eccentric walking is effective for sedentary people, older people, how the different types of eccentric exercise compare and the potential cognitive and mental health benefits.</p> <p>But, in the meantime, “eccentric walking” appears to be a beneficial exercise that will extend your healthspan. It may look a bit eccentric if we insert lunges while walking on the street, but the more people do it and benefit from it, the less eccentric it will become. <!-- Below is The Conversation's page counter tag.

"Eventful walk home": Barnaby Joyce explains why he was found collapsed on footpath

<p>Barnaby Joyce, the Nationals frontbencher, has recently found himself at the centre of public attention after a video surfaced showing him lying on a footpath in Canberra, seemingly in an inebriated state.</p> <p>In a statement to Seven's <em>Sunrise</em> on Monday morning, Joyce attributed the incident to mixing alcohol with prescription medication.</p> <p>“It was a very eventful walk home, wasn’t it,” he said to host Nat Barr. "I’m on a prescription drug, and they say certain things may happen to you if you drink, and they were absolutely 100 per cent right. They did.”</p> <p>Barr then replied: “So you mixed alcohol with prescription medication, did you, and this is what happened?”</p> <p>“That’s exactly what I said, yep,” Joyce responded.</p> <p>In the video footage captured on Lonsdale Street in Braddon, initially obtained by <em>The Daily Mail</em>, <span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Joyce can be seen lying on his back, mumbling into his phone, prompting concerns from passersby.</span></p> <p>Prime Minister Anthony Albanese urged Joyce to provide a credible explanation. “People will certainly make their own judgements on that," Albanese told the ABC. "People will see that footage, they will look for an explanation that has some credibility and they’ll look for leadership from the leader of the Liberal Party and the leader of the National Party about this.”</p> <p>Treasurer Jim Chalmers expressed concern for Joyce's wellbeing, calling for an explanation while refraining from personal attacks.</p> <p>The incident has prompted discussions within political circles, with Nationals leader David Littleproud stating that Joyce would receive the necessary support. However, Joyce's decision to skip a party meeting where the incident was to be discussed indicates ongoing uncertainty surrounding the situation.</p> <p><em>Images: Sunrise / Seven</em></p>

Joyous news as injured policewoman walks again after huge fundraiser

<p>Ella Cutler, the brave WA police officer who faced a <a href="https://www.oversixty.com.au/health/caring/police-officer-in-critical-condition-after-terrifying-cliff-fall" target="_blank" rel="noopener">life-threatening fall in Europe</a> just three months ago, has triumphantly walked out of the hospital, defying all odds. The inspiring journey of her recovery, coupled with the overwhelming support from a generous community, has captured the hearts of thousands of people around the country and even further afield.</p> <p>On that fateful day in Croatia, Ella's world took a devastating turn when she plummeted several metres from a wall at a popular tourist spot (image below), leaving her body shattered. Doctors initially gave her a mere five percent chance of survival, painting a grim picture for the spirited detective constable. However, Ella's determination, coupled with the unwavering support of her family and a compassionate community, has defied the bleak prognosis.</p> <p>Amid the challenges, Ella faced yet another hurdle as her insurer denied funding for both medical costs and the flight back to her home in Perth. The reason? She had been enjoying a night out and had a few drinks on the ill-fated evening. Undeterred by this setback, Ella's family launched a fundraiser to bridge the financial gap, and the response was <a href="https://www.oversixty.com.au/health/caring/positive-news-for-injured-wa-police-officer-in-croatia" target="_blank" rel="noopener">nothing short of extraordinary</a>.</p> <p>The community rallied together, pouring in close to $530,000 in donations from across the country. It became the largest GoFundMe campaign ever in Western Australia, showcasing the incredible power of collective compassion. This outpouring of support not only covered the substantial medical expenses but also became the lifeline that brought Ella back to her home in late September.</p> <p>A recent video shared by WA Police is a testament to Ella's indomitable spirit. Smiling, talking and walking with the aid of crutches and braces, she left rehabilitation at Fiona Stanley Hospital in Murdoch, just south of Perth. The joy in her eyes and the gratitude in her words were palpable as she expressed her thanks to the thousands who contributed to her recovery.</p> <p>"Thank you so much for bringing me home. Your kindness is overwhelming," Ella said, her words echoing the sentiments of a grateful heart.</p> <p>Ella, accompanied by her family, recently met with WA Police Commissioner Col Blanch, displaying an unwavering determination to return to the job she loves. Despite a laundry list of injuries, including fractures to her skull, spine, ribs and limbs – as well as punctured lungs – Ella remains undaunted. Her journey to full recovery is far from over, requiring months of care, multiple surgeries and extensive physical rehabilitation.</p> <p>As Ella takes each step toward recovery, she not only defies the odds but also stands as a living example of how a community united can overcome even the most challenging circumstances.</p> <p><em>Images: WA Police / Seven News</em></p>

How 22 minutes of exercise a day could reduce the health risks from sitting too long

<p><em><a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>People in developed countries spend an average of <a href="https://doi.org/10.1136/bjsports-2022-106568">nine to ten hours</a> a day sitting. Whether it’s spending time in front of a computer, stuck in traffic, or unwinding in front of the TV, our lives have become increasingly sedentary.</p> <p>This is concerning because prolonged time spent sitting is <a href="https://bjsm.bmj.com/content/54/24/1451?s=09&amp;int_source=trendmd&amp;int_medium=cpc&amp;int_campaign=usage-042019">linked to a number of health issues</a> including obesity, heart disease, and certain types of cancers. These health issues can contribute to earlier death.</p> <p>But a <a href="https://doi.org/10.1136/bjsports-2022-106568">new study</a> suggests that for people over 50, getting just 22 minutes of exercise a day can lower the increased risk of premature death from a highly sedentary lifestyle.</p> <h2>What the researchers did</h2> <p>The team combined data from two studies from Norway, one from Sweden and one from the United States. The studies included about 12,000 people aged 50 or older who wore wearable devices to track how active and sedentary they were during their daily routines.</p> <p>Participants were followed up for at least two years (the median was 5.2 years) during the study period, which spanned 2003-2020.</p> <p>Analyses took several lifestyle and health factors into account, such as education, alcohol intake, smoking status, and previous history of heart disease, cancer and diabetes. All this data was linked to national death registries.</p> <h2>A 22 minute threshold</h2> <p>A total of 805 participants died during follow up. The researchers found people who were sedentary for more than 12 hours a day had the highest risk of death (a 38% higher risk than people who were sedentary for eight hours).</p> <p>However, this was only observed in those who did less than 22 minutes of moderate to vigorous physical activity daily. So for people who did more than 22 minutes of exercise, there was no longer a significantly heightened risk – that is, the risk became generally similar to those who were sedentary for eight hours.</p> <p>Higher daily duration of physical activity was consistently associated with lower risk of death, regardless of total sedentary time. For example, the team reported an additional ten minutes of moderate to vigorous physical activity each day could lower mortality risk by up to 15% for people who were sedentary less than 10.5 hours a day. For those considered highly sedentary (10.5 hours a day or more), an additional ten minutes lowered mortality risk by up to 35%.</p> <h2>The study had some limitations</h2> <p>The team couldn’t assess how changes in physical activity or sedentary time over several months or years may affect risk of death. And the study included only participants aged 50 and above, making results less applicable to younger age groups.</p> <p>Further, cultural and lifestyle differences between countries may have influenced how data between studies was measured and analysed.</p> <p>Ultimately, because this study was observational, we can’t draw conclusions on cause and effect with certainty. But the results of this research align with a growing body of evidence exploring the relationship between physical activity, sedentary time, and death.</p> <h2>It’s positive news</h2> <p>Research has previously suggested <a href="https://bjsm.bmj.com/content/54/24/1499">physical activity may offset</a> health risks associated with <a href="https://www.jacc.org/doi/abs/10.1016/j.jacc.2019.02.031">high sedentary time</a>.</p> <p>The good news is, even short bouts of exercise can have these positive effects. In this study, the 22 minutes wasn’t necessarily done all at once. It was a total of the physical activity someone did in a day, and would have included incidental exercise (activity that’s part of a daily routine, such as climbing the stairs).</p> <p>Several studies using wearable devices have found short bursts of high-intensity everyday activities such as stair climbing or energetic outdoor home maintenance activities such as mowing the lawn or cleaning the windows can lower <a href="https://www.nature.com/articles/s41591-022-02100-x">mortality</a>, <a href="https://academic.oup.com/eurheartj/article/43/46/4801/6771381">heart disease</a> and <a href="https://jamanetwork.com/journals/jamaoncology/fullarticle/2807734">cancer</a> risk.</p> <p>A recent study using wearable devices found moderate to vigorous bouts of activity <a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(23)00183-4/fulltext">lasting three to five minutes</a> provide similar benefits to bouts longer than ten minutes when it comes to stroke and heart attack risk.</p> <p>Several other studies have found <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">being active just on the weekend</a> provides similar health benefits as <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2794038">being active throughout the week</a>.</p> <p>Research has also shown the benefits of <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2795819">physical activity</a> and <a href="https://jamanetwork.com/journals/jama/article-abstract/2809418">reducing sedentary time</a> extend to cognitive health.</p> <p>Routines such as desk jobs can foster a sedentary lifestyle that may be difficult to shift. But mixing short bursts of activity into our day can make a significant difference towards improving our health and longevity.</p> <p>Whether it’s a brisk walk during lunch, taking the stairs, or even a short at-home workout, this study is yet another to suggest that every minute counts.<!-- Below is The Conversation's page counter tag.

Bec and Lleyton Hewitt's son on track for Aussie Open

<p>Bec and Lleyton Hewitt's little boy is growing up fast! Just a few months past his 15th birthday, Cruz Hewitt continued to demonstrate that he's well on his way to following in his famous father's illustrious footsteps.</p> <p>In mid September, Cruz secured his inaugural professional win at the Darwin Tennis International, even though he was up against much older and more experienced competitors.</p> <p>That important first pro win came on a Sunday in the first round of qualifiers at the Darwin Tennis International, a 3-6, 4-6, 10-5 thriller over 25-year-old Brian Tran. Cruz then followed that up with another impressive win, 6-3, 6(4)-7, 10-3 over 21-year-old Jerome Iaconi in the second round, before suffering a 3-6, 1-6 loss against 24-year-old Jesse Delaney in the third round of qualifiers.</p> <p>Cruz was elated to share that his famous dad was overjoyed with his victory when he spoke to reporters, emphasising the significance of his win.</p> <p>Behind the scenes, Cruz's mother, TV star Bec Hewitt, now aged 40, is more determined than ever to ensure that her family avoids the pitfalls of history repeating itself – as when Lleyton himself went through the trials of becoming an elite-level tennis player.</p> <p>An insider <a href="https://www.nowtolove.com.au/celebrity/celeb-news/lleyton-hewitt-son-cruz-tennis-78956" target="_blank" rel="noopener">exclusively shared with <em>Woman's Day</em></a>, "There was always this underlying feeling that Lleyton's parents, Glynn and Cherilyn, really pushed their boy to get the best out of himself, and it was rumoured at the time that it was their way or the highway when it came to his tennis."</p> <p>As a result, Bec has spent years advocating for her more balanced parenting approach, steering Lleyton towards her gentler perspective on raising their children (Cruz has a big sister, Mia, who was born in November 2005, and a little sister, Ava, born in October 2010). <span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Now Cruz is shaping up to be a more well-rounded individual compared to his highly-pressured dad, thanks to Bec's belief that life should not solely revolve around tennis.</span></p> <p>Bec serves as a calming influence on Cruz, just as she does with their daughters Mia and Ava. Her aspiration for her son is to have him look up to players like Roger Federer, who epitomise true champions both on and off the court. What matters most to Bec is ensuring that Cruz's mental health is as robust as his tennis skills, and she is determined not to push him too hard in pursuit of success.</p> <p>The talented young athlete has inherited more than just his 42-year-old father's formidable two-handed backhand. When asked about his most recent victory, Cruz confidently remarked to local media: "I'm pretty stoked about getting that win because I had to come from behind. I was fired up, to be honest… It's cool getting to go to different places like here in Darwin, and it's a lot of fun. But I came here to test myself at this level against some older players and see how I fare."</p> <p>He playfully added, "I also get to miss school today because I won, so that's even better!"</p> <p>With the entire tennis world closely observing Cruz's every move, the question now arises: Can he break one of his father's longest-standing records? An insider shared, "Lleyton, who these days balances family life with coaching and commentary commitments, first qualified for the 1997 Australian Open at the tender age of 15 years and 11 months, becoming the youngest in the tournament's history.</p> <p>"He went on to win the 2001 US Open and the 2002 Wimbledon. There's no reason Cruz, who exudes more confidence than most kids his age on the circuit, can't achieve the same over the next few months."</p> <p>The insider shared, "When Cruz was seven, Lleyton expressed hope that his son would make the main draw at 14. While Bec knows he was simply dreaming big for his son, she wants to shield her boy from excessive pressure and offer unwavering support, win or lose."</p> <p><em>Images: Instagram</em></p>

Surprise! Scientists find falls likely when texting and walking

<p>It seems obvious that texting while walking is <a href="https://cosmosmagazine.com/people/behaviour/millennials-most-likely-to-text-and-drive/" target="_blank" rel="noreferrer noopener">risky</a> business.

I wondered: is this safe?” said senior author Dr Matthew Brodie, a neuroscientist and engineer at the University of New South Wales.</p> <p>“This has made me want to investigate the dangers of texting while walking. I wanted to know if these dangers are real or imagined and to measure the risk in a repeatable way.”</p> <p>Brodie and colleagues recruited 50 undergraduate students from UNSW to take part in the study.</p> <p>Participants walked across a specially built tiled surface, fitted with a tile that could slip out halfway through.</p> <p>They were asked to either walk across the surface normally, or walk across it while texting “the quick brown fox jumps over the lazy dog”.</p> <p>The students were strapped to safety harnesses so they couldn’t fall, and told they may or may not slip.</p> <div style="position: relative; display: block; max-width: 100%;"> <div style="padding-top: 56.25%;"><iframe style="position: absolute; top: 0px; right: 0px; bottom: 0px; left: 0px; width: 100%; height: 100%;" src="https://players.brightcove.net/5483960636001/HJH3i8Guf_default/index.html?videoId=6332776122112" allowfullscreen="allowfullscreen"></iframe></div> </div> <p class="caption"><em>The methods used in the experiment. Credit: Heliyon Brodie et al.</em></p> <p>“What surprised me is how differently people responded to the threat of slipping,” says Brodie.</p> <p>“Some slowed down and took a more cautious approach. Others sped up in anticipation of slipping. Such different approaches reinforce how no two people are the same, and to better prevent accidents from texting while walking, multiple strategies may be needed.”</p> <p>The researchers recorded motion data from the students as they moved and slipped, analysing how stable they were.</p> <p>They found that texting while walking made the students significantly less stable.</p> <p>Specifically, the students “trunk angle” – the angle of their torsos – varied more when they were slipping while texting. This means they were less stable.</p> <p>Participants were also less accurate texters when they did it while walking as opposed to sitting down, and least accurate when they did slip over.</p> <p>“Pedestrians should therefore be discouraged through new educational and technology-based initiatives (for example a ‘texting lock’ on detection of walking) from texting while walking on roadside footpaths and other environments where substantial hazards to safety exist,” conclude the researchers in their paper.</p> <p><em>Image credits: Shutterstock</em></p> <p><em><a href="https://cosmosmagazine.com/health/body-and-mind/texting-walking-falls/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/ellen-phiddian/">Ellen Phiddian</a>. </em></p> </div>

Jackie O’s hilarious walk of shame after wild Logies all nighter

<p dir="ltr">Jackie O didn’t let her 5am start time stop her from partying all night at the Logies afterparty even if that meant she had to show up to work wearing last night’s dress.</p> <p dir="ltr">In a hilarious video uploaded to Instagram, Jackie O shared behind the scenes footage of what it was like for a celebrity to do the walk of shame into work after a big night out.</p> <p dir="ltr">The video starts off with her walking down a footpath in her red strapless gown laughing as she said "this is embarrassing".</p> <p dir="ltr">When someone asked why she was still wearing last night’s dress she sheepishly replied:</p> <p dir="ltr">“I have not been home, I had the craziest night”.</p> <p dir="ltr">The radio host shared a bunch of clips from her wild all-nighter, spliced together with time stamps.</p> <p dir="ltr">She looked like she had a great time, partying with fellow entertainers Grant Denyer and Chris Brown.</p> <p dir="ltr">At 1:53 am Brown, who was shocked that Jackie was still at the afterparty incredulously asked her: "What the hell are you doing here?"</p> <p dir="ltr">The radio host replied: “I know, I know,” but she didn’t think too hard about it as she continued to party all night, only leaving when <em>KIIS FM</em> intern Pete Deppeler told her it was 4am.</p> <p dir="ltr">When she got in the studio, Kyle Sandilands beamed with joy when he saw his co-star and exclaimed: “Oh my god, you’re in the same outfit?”</p> <p dir="ltr">Jackie O sheepishly repeated the same answer and told him that she hadn’t been home, to which a shocked Kyle replied, “what do you mean you haven’t been home?”</p> <p dir="ltr">She later explained on the show that she didn’t intend to have a big night out and got carried away with the festivities, all while sober.</p> <p dir="ltr">"I was planning on leaving straight after I presented that award," she added.</p> <p dir="ltr">"My car was booked [and] ready to go.

Despite the restrictions, many patients still in need of his surgical skills are expressing disbelief over the situation.</p> <p>In a message posted to social media, Dr Teo has urged his supporters to join him in solidarity for a walk across Sydney Harbour Bridge – and dozens have already committed to the walk, which will take place in September.</p> <p>“Many have asked what you can do to show your support," wrote the embattled surgeon. "Well, I would be honoured if you would join me in solidarity on the Sydney Harbour Bridge.”</p> <p>Patients are rallying their friends and family to walk with Dr Teo on September 17, in a message that emphasised that Dr Teo remains determined and will be present for the event after flying in from Spain.</p> <p>The decision to work in China and other countries came after the Health Care Complaints Commission (HCCC) found Dr Teo guilty of "unsatisfactory professional conduct", a verdict he vehemently denies.</p> <p>Dr Teo addressed those affected by brain cancer, acknowledging the severity of the disease and emphasising the importance of the Charlie Teo Foundation in offering hope and support to those affected.</p> <p>Dr Teo affirmed that while he would be working in various countries, he still considers Australia his home. He expressed sadness over his recent experiences within the Australian medical system but remains motivated by the work he continues to do worldwide. The announcement of Dr Teo's decision to focus on China garnered hundreds of supportive comments from social media users, along with comments left on news articles.</p> <p>Dr. Teo confirmed that he would soon be performing complicated brain stem surgeries in China, acknowledging that his future in Australia is likely over. As he told the <a href="https://www.dailytelegraph.com.au/news/nsw/charlie-teo-ive-been-crucified-i-have-no-choice-but-to-try-china/news-story/61bb1af2516de2705d55143c53dece47" target="_blank" rel="noopener"><em>The Saturday Telegraph</em></a>: “I am not guilty of what I am accused of. I reject what they say I have done. They just don’t believe me, so why would I show remorse for something that I deny?”</p> <p>“I could appeal, I think I would win. They wouldn’t be able to prove beyond a reasonable doubt the things they have accused me of because they are not true. But I’m not sure I have the strength to run an appeal. Furthermore, I don’t have the money to do so,” he said.</p> <p>“And then the whole emotional turmoil.”</p> <p>Dr Teo instead will focus on saving lives in countries that will allow him to. “I have just been granted privileges in China, in three different hospital,” he said. “The fact that I have been crucified over here didn’t appear to affect their decision, so I am going over there to check the facilities, make sure they are good. They just bought the latest MRI for me.”</p> <p>Dr Teo said he was committing to a future in China “because they have committed to me” and would continue to do the occasional cases in Europe and parts of Southeast Asia that required his expertise.</p> <p>He expressed disappointment but not surprise at the conditions placed on his practicing certificate following an investigation into two brain surgeries with adverse outcomes. Dr Teo categorically denied any failure to obtain proper consent or lacking empathy for his patients. He expressed his reluctance to appeal the decision due to the emotional turmoil and financial constraints associated with it. Instead, he will focus on saving lives in countries that permit his expertise.</p> <p>Having recently been granted privileges in three hospitals in China, Dr Teo expressed his commitment to this new chapter in his career. He mentioned that the accusations against him would not hold up if challenged but admitted uncertainty regarding his ability to endure an appeal process.</p> <p>Dr Teo's primary concern lies in ensuring quality facilities and patient care in China. While he plans to continue performing occasional cases in Europe and Southeast Asia, he lamented the fact that he can no longer assist patients in his home country.</p> <p>Dr. Teo criticised the recent findings by the HCCC, stating that they send a negative message to doctors who offer contrary second opinions. He expressed concern that neurosurgeons across Australia may become reluctant to undertake risky surgeries, fearing media scrutiny and judgment from colleagues who lack the necessary expertise to treat complex tumour cases.</p> <p>Dr Teo also revealed that he continues to receive regular calls from individuals suffering from rare brain tumours seeking his help, but he is forced to turn them away.</p> <p><em>Image: Wikimedia</em></p>

Tracking the shift in meanings of ‘anxiety’ and ‘depression’ over time

<div class="copy"> <p>The mental health terms ‘anxiety’ and ‘depression’ have become increasingly pathologised since the 1970s, according to analysis by Australian researchers of more than a million academic and general text sources. </p> <p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0288027" target="_blank" rel="noreferrer noopener">Publishing</a> in PLOS ONE, psychology and computer science researchers from the University of Melbourne tracked the frequency and meaning of the concepts ‘anxiety’ and ‘depression’ from 1970 to 2018, and words that occurred in their vicinity.</p> <p>Using natural language processing, the team analysed more than 630 million words across 871,340 academic psychology papers, as well as 400,000 texts from general sources such as magazines, newspapers and non-fiction books.</p> <p>Paper co-author psychologist Professor Nicholas Haslam has a long standing interest in how mental health terms change their meanings over time, particularly the way harm-related words like bullying, abuse and trauma tend to expand over time, incorporating new, and often less severe kinds of experiences.</p> <p>Haslam says that trend reflects progressive social change and a rising sensitivity to harm and suffering in our culture. “We emphasize [that’s] mostly a good thing,” he says.</p> <p><iframe title="The Emoji Squad: The Mysterious Group Behind the Little Icons We Love 🤝" src="https://omny.fm/shows/huh-science-explained/the-emoji-squad-the-mysterious-group-behind-the-li/embed?in_playlist=podcast&amp;style=Cover" width="100%" height="180" frameborder="0"></iframe></p> <p>The terms ‘anxiety’ and ‘depression’ were selected for analysis as prevalent, prominent mental health concepts.</p> <p>The researchers expected the emotional intensity and severity of the two terms to reduce over time as the frequency of their use increased.</p> <p>That expectation was informed by previous research using a similar approach, co-authored by Haslam and <a href="https://sciendo.com/article/10.58734/plc-2023-0002" target="_blank" rel="noreferrer noopener">publishing in</a> Sciendo, where increasing use of the word ‘trauma’ since the 1970s was associated with a shift in meaning including a broadening of use and declining severity.</p> <p>They hypothesised a similar trend for ‘anxiety’ and ‘depression’.</p> <p>“Well, we didn’t find what we expected,” Haslam says.</p> <p>Contrary to expectation, the emotional severity associated with anxiety and depression increased linearly over time. </p> <p>The authors say this is possibly due to growing pathologising of the terms, given their analysis shows use of the words increasingly linked to clinical concepts. </p> <p>In particular, the terms ‘disorder’ and ‘symptom’ have become more commonly associated with ‘anxiety’ and ‘depression’ in more recent decades, the paper says, finding similar patterns in both the academic and general texts. </p> <p>Anxiety and depression were also increasingly used together, compared to use in the ‘70s where the terms were more likely to refer to separate things.</p> <p>Haslam says, these shifts in meaning could reflect growing awareness of mental health in society and more research is needed into the implications, he says. </p> <p>But he notes this is an area where there can be “mixed blessings”.</p> <p>On the one hand, greater awareness of anxiety and depression can help people to seek appropriate treatment; and on the other, pathologising more ordinary variations in mood can risk become self-fulfilling or self-defeating.</p> <p>At a more systemic level, pathologising the milder end of the mental health spectrum could risk leading to a misallocation of resources away from the more severe and urgent mental health problems, Haslam says.</p> <p><em>Image credits: Getty Images</em></p> <p><em><a href="https://cosmosmagazine.com/people/social-sciences/tracking-the-shift-in-meanings-of-anxiety-and-depression-over-time/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/petra-stock">Petra Stock</a>. </em></p> </div>

Here’s why you need to go for a walk every single day

<p><strong>The benefits of walking every day </strong></p> <p>Twenty summers ago, Nancy Duguay stood at the side of a soccer pitch in watching her 11-year-old son sprint back and forth, and wished she had a cigarette.</p> <p>Duguay, then 39 and a cardiac-rehab nurse, was trying to quit smoking after having the habit for more than half her life. She’d sneaked her first cigarettes from her parents’ packs as a teen and hadn’t stopped since. With her hands empty as she waited for her son’s practice to end, the urge for a puff gnawed at her.</p> <p>Behind the field, the heavily forested Sugarloaf Mountain stood guard. As a kid, Duguay and her friends regularly hiked the mountain and picnicked on its peak.</p> <p>Then an idea struck her: walking instead of smoking. She told another parent that she would be back in time to pick up her son and then set off for the mountain. “In just my regular sneakers, a pair of shorts and a T-shirt,” she remembers.</p> <p>Duguay’s heart pounded as she climbed, and she stopped often to rest. When she arrived at the top, she took in the view that sweeps over the city and across the river to the rolling hills of the Gaspé Peninsula.</p> <p>“I just felt so good,” says Duguay. “My natural endorphins kicked in, and the craving was gone.”</p> <p>Almost every day since, she has gone for a walk – and the habit has changed her life. Not only did she quit smoking, but her resting heart rate dropped from 80 beats per minute to 60. The ritual has given her a lot more, as well: stress relief, mental-health management, and a sense of community.</p> <p>“There’s a psychological and physical need to do it now,” she says. “I want to keep healthy and keep moving.” Keep reading to discover more incredible health benefits of walking every day.</p> <p><strong>It's good for your body</strong></p> <p>A growing body of research confirms what Duguay discovered: there are enormous benefits in walking every day. According to a report from the Canadian Academy of Sport and Exercise Medicine, walking for 150 minutes a week can reduce the risk of most major chronic diseases by 25 to 50 per cent. In fact, light to moderate exercise has been found to be more effective than medication during rehabilitation after a stroke. For prevention of diabetes and as a secondary treatment of heart disease, walking is equally as effective as taking drugs.</p> <p>In 2019, a Journal of Clinical Oncology study reported that a small amount of physical activity – such as taking a brisk walk for 20 minutes or more a day – is linked to a lower risk of seven types of cancer. Meanwhile, more walking means better sleep, too. In a recent study of middle-aged men and women, the participants who took more steps during the day slept better at night.</p> <p>“We need to start thinking about walking as a healthy activity,” advises Dr Jane Thornton, a family physician in London, Ontario. She advocates for the idea that we consider physical activity as medicine – a philosophy that grew out of personal experience. Thornton was a shy, sedentary 14-year-old when she signed up for a beginner’s rowing class in Fredericton. While her physical fitness improved, a new social circle opened to her and her grades went up. Thornton went on to become a world-champion rower and represented Canada at the 2008 Olympics.</p> <p>A few years after competing in the Olympics and shortly before retiring from sport, she enrolled in medical school. She was surprised by the lack of information provided to physicians-in-training about the benefits of exercise. “For whatever reason, there just wasn’t any content at all on physical activity,” she says.</p> <p>In 2014, Thornton started working on a campaign with the Canadian Academy of Sport and Exercise Medicine to get doctors to prescribe physical activity for patients – including walking. “I don’t think it’s a panacea for everybody, but it is one of the easiest, best solutions we have at our disposal,” she says.</p> <p>One significant reason that walking is so good for us is fairly straightforward: when we move, our hearts work harder to transport blood to the working muscles and organs. That repeated effort strengthens the heart muscle, making it pump more efficiently at all times, sending blood around the body with fewer beats per minute. Exercise also improves the function of blood vessels, with one analysis reporting that aerobic exercise can improve our vascular health.</p> <p>Walking helps build other muscles, too, especially in the lower body, and improves balance and strength. Physiotherapists like to say “Motion is lotion.” When our bodies don’t move enough, they stiffen. Ligaments, tendons and muscles tighten when they’re not used, causing pain in joints. For back pain, especially, movement can help. When we walk, we activate the muscles that run along the spine, strengthening them. “Pain and function improve just by putting those muscles into play,” Thornton says.</p> <p>Hospitals have also begun to embrace the value of walking. At Mount Sinai in Toronto, older patients weren’t always encouraged to get up from bed because of the risk of falling. About ten years ago, that changed. Assisted by doctors, nurses and volunteers, patients are now prompted to walk to the bathroom, explore the hallways and get out of bed to eat their meals.</p> <p>Since that change, fewer patients require catheters and suffer pressure ulcers. On average, they spend less time in the hospital. “Every day that an older person is in bed, they lose five per cent of their physical functioning,” says Dr Samir Sinha, Mount Sinai Hospital’s director of geriatrics. “So getting them up and walking can reduce the chance that grandma might not be able to return home.”</p> <p><strong>It's good for your mental health </strong></p> <p>One of the most important benefits of walking every day is that it’s equally beneficial for our mental health. For Duguay, walking helped her through some of the toughest periods in her life. When her mother died of cancer, Duguay turned to the mountain to walk through her pain. “I would cry all the way up the mountain,” she remembers. In this way, walking became her antidepressant.</p> <p>According to a 2019 study led by researchers at Harvard University, people with a genetic risk for depression are less likely to struggle with the condition if they exercise – even performing light physical activity like walking.</p> <p>Walking also reduces the risk of dementia and Alzheimer’s disease. In 2019, the World Health Organization released new guidelines on dementia prevention, and its top recommendation was to get more exercise.</p> <p>“We’ve always known that exercise is good for your heart, but we’re now making a connection between exercise and cognitive improvements,” said Dr Saskia Sivananthan, chief research &amp; knowledge, translation and exchange officer at the Alzheimer Society of Canada.</p> <p>Although that link isn’t yet fully understood, Sivananthan says there are a number of possible explanations: increased blood flow to the brain increases the organ’s cell growth; physical activity stimulates certain hormones that improve well-being and may reduce brain-matter loss linked to cognitive function; and walking might also reduce inflammation in the brain.</p> <p>Meanwhile, one study from McMaster University has shown that aerobic activity that incorporates intervals of higher-intensity exertion improves memory function. According to Dr Jennifer Heisz, who worked on the research, walking promotes production of a protein, BDNF, that spurs growth of new brain cells. These cells help us create high-fidelity memories – “the type we need every day to locate our car in a busy parking lot and recognise a friend in a crowd,” she said.</p> <p><strong>It's good for your social life</strong></p> <p>Jim Button, a 56-year-old entrepreneur, was diagnosed with kidney cancer in 2014. He underwent successful surgery but, less than two years later, he learned that his cancer was back, had spread and was terminal.</p> <p>Button knew that exercise would help keep him as healthy as possible. He started walking five kilometres a day. Before his diagnosis, he’d meet with business contacts and friends at coffee shops. Now he asks them to join him on a walk. Every day over the last three years that his health has allowed, Button has gone for a walk, all the while expanding the range of his walking partners – he regularly strolls with strangers who reach out to him seeking business advice, or people recently diagnosed with cancer and other illnesses.</p> <p>“I’ve discovered that not a lot of people go for walks,” Button says. “And when they do, it opens up their mind to be a bit more honest about whatever challenge they would like to talk about.” On some walks, he says, conversation never slows. On others, little is said but much is shared, even silently.</p> <p>Inspired by Button’s strolls, Dr Lisa Bélanger – founder of Knight’s Cabin, a Canadian charity for cancer survivors and their supporters – helped found an initiative in Calgary called Walk It Out. The program is like other peer support groups, but participants walk outside while they share their experiences with the disease. “More than in a sit-down, face-to-face meeting, walking seems to allow a conversation to flow naturally,” she says.</p> <p>Bélanger, who is an expert in behavioural medicine, adds that walking has the power to undo negative thought patterns. “If you’re thinking about a problem and you go for a walk, the activity in your brain changes, and you learn and think better,” she says.</p> <p>Like Button, Nancy Duguay has corralled her community around her daily walks. The more she walked, the more people around her saw the benefits and started doing it, too. Her husband, Roger, began to accompany her on hikes on their holidays. And about seven years after Duguay’s first walk up a nearby mountain, her sister decided to try it. Now she, too, takes a walk every day, and they often go together. A small community of walkers has formed around them.</p> <p>“We’ll meet people coming down and say, ‘This was a tough one today. It was really slippery, but boy, you know, it’s worth it.’”</p> <p><strong>Put your best food forwards</strong></p> <p>To experience all the benefits of walking every day, treat it like a workout, says personal-fitness trainer Korey Samuelson:</p> <p>Walk with an upright posture, your head held straight, not looking up or down. Keep your gaze about five metres ahead.</p> <p>To move faster, put more bend in your elbows.</p> <p>Swing your arms forwards and back; moving them across the body isn’t efficient. “Just like sprinting, arm movement is important for strong walking,” says Samuelson.</p> <p>When your lead foot lands on the ground, roll from heel to toe. Your footwear should be pliable enough to allow the natural movement across your foot.</p> <p>To speed up, increase your strides per minute rather than elongating your strides. More steps per minute means you’ll travel further, faster.</p> <p>Use Nordic walking poles to increase your heart rate and burn more calories.</p> <p>Intersperse intervals of brisk walking with periods at a slower pace.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/heres-why-you-need-to-go-for-a-walk-every-single-day" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

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.

Vets share their 5 best tips for safer dog walks – and 5 things never to do

<h2>Dogs need exercise</h2> <p>Dogs need physical exercise –  and as their owner, those daily steps add up for you, too. A 2017 study published in BMC Public Health found that dog owners walk an average of 22 extra minutes per day. That’s exercise that counts toward The Heart Foundation’s recommended 150 minutes a week of moderate-intensity exercise.</p> <p>Walking outside has some major health perks for you…and, says veterinarian, Dr Megan Conrad, regular walks provide excellent mental stimulation for your pooch.</p> <p>However, Dr Conrad and some fellow veterinarians told us there are some definite do’s and don’ts of dog walking that’ll help keep you and your pup safe and strolling happily for ages to come.</p> <h2>Do: Know your dog’s walking needs</h2> <p>In general, daily walks are recommended for most dogs, Dr Conrad says. Still, “the length of your walk very much depends on breed, age, and overall physical health.” A young border collie can go for several kilometres, while an older mini poodle is likely to need a shorter walk.</p> <p>The average adult dog needs about 20 to 45 minutes of moderate exercise twice a day, which can include a brisk walk, says veterinarian, Dr Whitney Miller. But, Dr Miller says, it’s a good idea to check with your pet’s veterinarian to determine his or her individual exercise needs.</p> <h2>Don’t: Walk too much too soon</h2> <p>“Just like we would not go out and run a marathon without training first,  you cannot expect your dog to go long distances right away,” Dr Karwacki says. When you’re establishing a walking routine, go short distances first and see how your dog is doing before you tack on more mileage.</p> <h2>Do: Make adjustments for the weather</h2> <p>“The general rule is if it’s too hot or too cold for you to be outside, it’s too much for your dog as well,” says veterinarian Dr Amber Karwacki.</p> <p>This is especially true for breeds like French bulldogs, pugs, or Boston terriers that don’t handle high temperatures well. One way around the heat is to aim for early morning or nighttime walks – just make sure to equip yourself and your dog with high-visibility gear like reflective clothing and lights (and carry a torch!).</p> <p>If possible, choose an area or route that allows your dog to walk on soft grass or dirt, as this helps prevent damage to their paw pads, Dr Miller says. “If you are walking on cold ground, booties can help prevent your pet’s paws from injury, keep snow and ice from getting stuck between the pads, and provide a barrier against ice melt,” she adds.</p> <p>If you’re walking on pavement during the summer, using paw protection (and bringing plenty of water!) is a good idea, too.</p> <h2>Do: Watch your dog’s behaviour</h2> <p>“Dogs may slow down, look in your direction, or outright refuse to move if they are feeling tired or don’t want to walk,” Dr Conrad says – and it’s important to respect this cue. Take notice of any excessive panting or unusual fatigue as well, Dr Miller adds, as these are clear signs to end the walk.</p> <p>If you sense that your dog is peeing more than usual, you should contact your vet – this could be a sign of illness.</p> <h2>Do: Let your dog sniff around</h2> <p>“Behaviourally, there’s nothing wrong with your dog frequently stopping to sniff their environment, and it can be good enrichment for them,” Dr Miller explains. “Sniffing is one of the main ways your dog experiences their environment, and there can be lots to take in on a walk, even in a familiar area.”</p> <h2>Do: Use positive reinforcement</h2> <p>Avoid reprimanding your dog or using other forms of punishment, even if it seems mild, like pulling on their collar, Dr Miller says. Research, such as one 2020 study, has shown that aversive-based training can cause stress and confusion in dogs, and this can lead to poor behaviour – possibly only because they don’t understand.</p> <p>“Positive reinforcement is proven to be effective,” Dr Miller says. “It promotes a focus on teaching dogs what we want them to do, such as having good manners, rather than focusing on behaviours we deem undesired.”</p> <p>You can use treats to reward your dog when they stay politely at your side, when they observe other dogs calmly instead of charging after them, and when they return their attention to you after something distracts them.</p> <h2>Don’t: Use retractable leashes</h2> <p>Retractable leashes allow too much freedom to explore in places that may be dangerous, Dr Conrad says – and they can make it difficult to keep control of your dog. Some larger breeds of dogs may even be able to break them, and they’re known for causing skin burns, Dr Karwacki adds.</p> <p>Here, it’s also important to note the findings of an April 2023 sports medicine study at Johns Hopkins University. A team of doctors analysed 20 years’ worth of national data and reported that on average, around 21,000 people per year seek treatment for injuries related to walking their pups on leashes. The data suggests that the majority of these injuries occur in individuals between age 40 and 64, and the most common reported injuries are finger fractures, traumatic brain injury, and shoulder sprains and strain.</p> <p>That’s one more reason to choose a stable leash (not a retractable one), pay attention to your walk (don’t lose your focus by looking at your phone or getting otherwise distracted), and be mindful of the size of dog you’ll be able to manage for the coming years when you’re looking to bring a new canine companion into your life.</p> <h2>Don’t: Let them off the leash</h2> <p>Unless you’re in a dog park, “it is essential to always keep your dog on a leash when out on a walk,” even if they’re well-behaved and trained, Dr Miller says. “You may encounter local wildlife and other people or dogs that could react negatively toward an off-leash dog or could distract your dog.”</p> <p>Dr Miller recommends using a no-pull harness that’s well-fitted (meaning it doesn’t restrict your dog’s range of motion) to encourage good behaviour and limit accidental negative reinforcement, like pulling on their collar. “If your dog gets excited and pulls during the walk, simply stop walking and reward them when they are exhibiting the desired behaviour of a loose leash,” she explains. “Continue to reward while walking when your dog is at your side and not pulling. Patience and consistency are important for reinforcing good manners.”</p> <h2>Don’t: Approach other dogs without permission</h2> <p>“Some dogs are reactive or nervous around other dogs, and having a strange dog come up to them can be intimidating and scary,” Dr Conrad says.</p> <p>Plus, not every person will be comfortable with you interacting with their pet, so be sure to over-communicate and seek permission, adds Dr Miller. (Also, stay fully focused – on-leash greetings can cause leashes to tangle up, presenting safety risks for both the dogs and the walkers.)</p> <h2>Don’t: Walk right after they eat</h2> <p>Avoid going on a long walk with your dog if it’s within an hour of them eating a large meal, Dr Miller says. This reduces the risk of stomach bloat, which can be harmful to your dog. (Besides, is there any feeling more satisfying than putting their breakfast bowl in front of them right after your morning walk? We think not.)</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/pets/vets-share-their-5-best-tips-for-safer-dog-walks-and-5-things-never-to-do" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>
