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

<p><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.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/209004/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/deborah-lancastle-1452267">Deborah Lancastle</a>, Associate Professor of Psychology, <a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Best cities to discover on foot revealed

<p dir="ltr">When it comes to travelling and exploring new places, there is no better way to experience everything a new city has to offer than just by walking around. </p> <p dir="ltr">By keeping on your feet rather than using public transport, you get the chance to explore more hidden corners of your destination and truly soak up the new culture, all while getting your steps in. </p> <p dir="ltr">That being said, there are definitely some cities that are easier to traverse on foot than others. </p> <p dir="ltr">But now, one company has put in the hard work to determine the 100 best cities around the world for travellers who want to walk their way to new experiences. </p> <p dir="ltr"><a href="https://www.guruwalk.com/">GuruWalk</a>, a company that offers free walking tours worldwide, has compiled the list based on booking and search data for 800 cities across 120 countries. </p> <p dir="ltr">In terms of countries as a whole, Spain topped the list with 28 cities appearing in the top 100, while Rome, Italy took out the top spot for most walkable city. </p> <p dir="ltr">Rome’s walkability is largely due to the location of the tourist hotspots, with the world-class attractions all located close to each other. </p> <p dir="ltr">GuruWalk comments, “The sheer number of monuments it hosts sometimes causes tourists to not even know where to start.”</p> <p dir="ltr">“So it’s not surprising that Rome hosts more guided tours than any other place.”</p> <p dir="ltr">Check out the entire top ten list below. </p> <p dir="ltr">10.

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.

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. We took these measurements before the study started, at four weeks, after the conventional walking period, and at four and eight weeks into the eccentric walking period.</p> <p>We also tested their cognitive function using a digit symbol-substitution test at the same time points of other tests. 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.

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.

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. But while there has been plenty of research showing it’s a dangerous distraction, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0966636217309670" target="_blank" rel="noreferrer noopener">some</a> <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0179802" target="_blank" rel="noreferrer noopener">studies</a> have suggested that younger people are better at negotiating obstacles while on their phones.</p> <div class="copy"> <p>A study <a href="https://dx.doi.org/10.1016/j.heliyon.2023.e18366" target="_blank" rel="noreferrer noopener">published</a> in <em>Heliyon</em> has refuted this, finding that university students are more likely to fall if they walk while texting.</p> <p>It also found they’re less accurate texters while walking.</p> <p>“On any day it seems as many as 80% of people, both younger and older, may be head down and texting. 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.

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>

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

<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>

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.co.nz/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.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/208655/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/robin-smit-594126">Robin Smit</a>, Adjunct Associate Professor, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p><em>Image credits: </em><em>Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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.co.nz/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>

7 hot things to do this winter

<p>The best thing about winter in Australia is that in most parts of the country the weather doesn’t stop you from spending time outside. While swims at the beach might be out, there are still many things you can do out in the fresh winter air. We’ve rounded up some of our favourites.</p> <p><strong>1. Christmas in July picnic</strong><br />While people may think picnics are a summer-only activity, when it’s a sunny winter's day there is nowhere better to be than outdoors. As long as you suitably rug up, a picnic in your local park with family and friends is the perfect way to spend the day. With July coming up why don’t you get your family and or friends together and throw a Christmas in July party. It’s even an appropriate time get out the Christmas jumpers – something we cannot do on December 25th in this country.</p> <p><strong>2. A trip to the zoo</strong><br />Visiting the zoo is a great day out for all, young and old. Many zoos across the country put on special shows and activities during the school holidays (think June/July), so this is a great time to think about taking younger family members or the grandkids.</p> <p><strong>3. Wine and cheese tasting</strong><br />Whether you want to head out to some wineries for the day or have your own wine and cheese tasting soiree at home, winter is the perfect time to kick back with a lovely glass of red and a platter of cheeses. While Australia has many amazing wineries that everyone should try, we also love the idea of holding a wine tasting party. You can assign one type of wine to each of your guests and even theme the day (wines from one country or each person brings a wine from where they grew up) to make it more fun.</p> <p><strong>4. Walk in a national park</strong><br />We are so blessed with beautiful national parks in Australia, and many of them have lots of walking trails ranging from easy to more strenuous. While rainy, snowy or extremely windy days won’t be ideal for heading out for a walk, the crisp winter air combined with the sun offers the perfect conditions for a long walk. Just don’t forget a raincoat, some water and your mobile phone in case you need them.</p> <p><strong>5. A day trip to a remote pub</strong><br />Life is all about experiences and they say that those who mix things up, are generally happier people. So quick, get out of town for the day. Research small towns nearby and look for a lovely pub to go for a nice lunch at. You might even want to make a special playlist of old songs to make the car journey extra fun.</p> <p><strong>6. Have a bake off with your friends</strong><br />It is winter, so there are bound to be some rainy or snowy days. On these days when you’re restricted to indoor activities, why not invite the grandkids, family or friends over and have a mini bake-off. Competition aside, at the end of the bake-off you’ll have some warm treats to enjoy with a nice cuppa.</p> <p><strong>7. Start a winter book club</strong><br />There’s no better time to start a book club than during winter. Not only is winter the perfect time to curl up on the couch with a blanket and catch up on reading, it is also a time when you’ll be more inclined to spend time indoors by the fire or heater. Why not turn your extra time spent reading into a book club? It gives you an excuse to catch up and spend hours on end chatting with friends – even if the conversation veers away from the book.</p> <p><em>Images: Getty</em></p>

Are you financially literate? Here are 7 signs you’re on the right track

<p>With the cost of living and interest rates rising, a growing number of Australians are struggling to manage their <a href="https://www.smh.com.au/money/planning-and-budgeting/almost-half-of-australia-is-financially-stressed-here-s-one-way-to-fix-it-20221011-p5bowq.html">finances</a>. Many are experiencing real <a href="https://www.anu.edu.au/news/all-news/australians-under-increasing-financial-stress#:%7E:text=The%2520level%2520of%2520financial%2520stress,say%2520they%2520are%2520struggling%2520financially">financial stress</a>.</p> <p>But even in the best of times, managing your finances is hard. Every day, you’re making complex financial decisions (some of which carry huge ramifications) and there are more financial products and services available than ever before. Navigating this minefield can be overwhelming and lead to financial anxiety.</p> <p>Being financially literate helps. But what does “financial literacy” mean in practice?</p> <p>Here are seven signs you’ve got the basics covered.</p> <h2>1. You track your cashflow</h2> <p>By tracking your cashflow on a regular basis, you’re ensuring your expenses don’t exceed your income. In other words, you make sure you’re earning more than you spend.</p> <p>A good sign you’ve successfully managed your cashflow is that you have a surplus or a buffer.</p> <p>These left-over funds can be used to boost savings, pay off debt or meet other financial commitments.</p> <p>Cashflow management allows you to assess whether there are opportunities to increase your savings and/or reduce spending. Being able to manage your earnings and spending is a key financial skill.</p> <h2>2. You have a budget – and you follow it</h2> <p>Setting and following a budget requires financial discipline, which is a key part of financial literacy.</p> <p>By following a budget, you’re putting a measure in place to live within your means and reduce the risk of overspending.</p> <p>With all the competing demands that come with managing money, your budget can be a tool to keep you on track. And developing this habit over time can empower you to make wise financial decisions.</p> <h2>3. You understand the difference between good debt and bad debt</h2> <p>Love it or hate it, debt forms part of our financial portfolios and sustains the financial institutions we interact with. Knowing how to make debt work for you is a skill and a sign of good financial knowledge. It is crucial to understand the difference between good debt and bad debt.</p> <p>Good debt is debt used to improve your long-term financial position or net worth, such as a home loan.</p> <p>Bad debt tends to be consumption-driven and doesn’t have lasting value. Examples include payday loans or retail accounts.</p> <h2>4. You have your money in various places</h2> <p>One of the key concepts of financially literacy is understanding the importance of diversification.</p> <p>By having your money spread across various places (such as a savings account, property, the share market, superannuation and so on), you’ve reduced the concentration of risk.</p> <p>This helps protect your wealth in tough economic times.</p> <h2>5. You understand how financial assets work, along with their pros and cons</h2> <p>Financial assets refers to things like cash, shares and bonds. It’s important to understand how financial assets work and how they can either help or hurt your financial position.</p> <p>For instance, savings accounts are a safe financial instrument that earn interest on the amount accumulated within the account. But the fact they’re so safe also means that they won’t outperform inflation.</p> <p>This type of knowledge is an imperative part of financial literacy.</p> <h2>6. You’re aware of your financial strengths and weaknesses</h2> <p>Financially literate people reflect on their capabilities.</p> <p>When you can appreciate where your financial strengths and weaknesses lie, you can make better financial decisions and prioritise your needs.</p> <p>On the other hand, being oblivious to your strengths and weaknesses means you miss opportunities to improve your financial health.</p> <p>For example, perhaps you buy unnecessary stuff when you feel sad. Or maybe you panic when faced with tough financial choices and make quick decisions just to make the problem go away.</p> <p>Neglecting to reflect on patterns of behaviour can lead to serious and possibly irreversible financial mistakes.</p> <h2>7. You set financial goals and put measures in place to meet them</h2> <p>Financially literate people plan for their finances. This involves setting goals for either earnings, savings, investments, and debt management or putting measures in place to protect wealth (via, for example, insurance to protect your wealth against loss).</p> <p>Setting goals is one thing, but it’s also important to have a system and habits in place to achieve them.</p> <p>Make sure you understand what you’re trying to achieve with your goals, why the goals are important and how you’ll achieve them.</p> <p>Boosting your financial literacy can feel tough at first. But tackling your finances head on, controlling spending, participating in financial markets, handling debt, being able to understand financial assets and working towards financial goals can help you feel in control of your financial situation.</p> <p><em>This article originally appeared on <a href="https://theconversation.com/are-you-financially-literate-here-are-7-signs-youre-on-the-right-track-202331" target="_blank" rel="noopener">The Conversation</a>.</em></p> <p><em>Images: Getty</em></p>

"I started walking the long way": many young women first experience street harassment in their school uniforms

<p>Can you remember the first time you were harassed in a public space? What comes to mind? Can you remember how old you were, or what you were doing? Perhaps this is not something you have personally experienced, although we know <a href="https://australiainstitute.org.au/report/everyday-sexism/">87% of young Australian women</a> have been harassed in public.</p> <p>We spoke to 47 adult women and LGBTQ+ people in <a href="https://www.streetharassmentjustice.com/">our recent study</a> on street-based and public harassment about their earliest memories of feeling sexualised, uncomfortable or unsafe on the street. Many mentioned they first experienced street harassment in their school uniforms. We heard variations of the phrase “it happened when I was in my school uniform” repeatedly from participants.</p> <p>For many, <a href="https://theconversation.com/whistling-and-staring-at-women-in-the-street-is-harassment-and-its-got-to-stop-38721">street harassment</a> began or became more frequent when they started wearing a high school uniform. Some participants, however, reflected on experiences from when they were even younger, wearing a primary school uniform. </p> <p>Studies from the United Kingdom have shown <a href="https://plan-uk.org/street-harassment/its-not-ok">35% of girls</a> wearing school uniforms have been sexually harassed in public spaces. Despite the importance of schools in the daily lives of young people, and the high rates of street harassment they experience, there’s been surprisingly little attention paid to the harassment of young people in school uniform. </p> <p>Findings from our <a href="https://www.tandfonline.com/doi/full/10.1080/09540253.2023.2193206">new research</a> show school-related harassment is a serious issue that has largely flown under the radar in Australia.</p> <h2>It happens beyond the school gates</h2> <p>We know young people experience <a href="https://researchdirect.westernsydney.edu.au/islandora/object/uws:55181/">sexual</a>, <a href="https://www.glsen.org/sites/default/files/2019-10/GLSEN%202015%20National%20School%20Climate%20Survey%20%28NSCS%29%20-%20Executive%20Summary.pdf">homophobic and transphobic</a>harassment from their peers and even teachers while they’re at school. </p> <p>But participants also told us about harassment occurring outside their school grounds. This was perpetrated by strangers (usually individual adult men, or groups of adult men), while they were in uniform and, therefore, clearly identifiable as school children. </p> <p>This took many forms, ranging from catcalling, staring or leering, wolf-whistling, and being followed by men in cars while walking to school, through to public masturbation and men rubbing themselves against victim-survivors (usually while travelling to school on public transport), sexual assault and rape. </p> <p>As one interviewee told us, "walking from high school to home […] that’s where most of the harassment I’ve experienced happened […] As soon as I stopped wearing a school uniform it happened less. So that’s disgusting for a lot of reasons."</p> <p>As another interviewee shared, these experiences were really scary not just because of what was happening at that moment but because the perpetrator “knows which school you go to” because of the uniform worn.</p> <h2>The ‘sexy schoolgirl’</h2> <p>Why is it that young people – and particularly young women and girls – are so routinely harassed in school uniform? We found harassment of schoolgirls was seen as being culturally sanctioned through the “sexy schoolgirl” trope. </p> <p>As one interviewee noted, "when you go on Google images and search for ‘school boy’ it will come up with a five-year-old boy but then ‘school girl’ it will come up with the sexy school girl costume."</p> <p>Participants discussed being targeted because they were viewed as vulnerable and (paradoxically) as both sexually innocent and sexualised, "that was part of the allure for them [the perpetrators], the innocence of a schoolgirl, a fearful schoolgirl in that situation, was like hot to them, they were really getting off on it."</p> <p>Another interviewee told us, "I went from being an innocent child to a child that felt uncomfortable and didn’t know why I was sexualised – and I didn’t understand it because I didn’t understand what sex really was."</p> <p>Because they were so young, many participants often lacked a framework or language to understand their experiences. For many, these experiences were also so routine they simply formed part of the background hum of everyday life. </p> <p>It was often not until years after these formative experiences that participants were able to articulate them as sexual harm and reflect on the impacts. </p> <h2>Trying to avoid harassment</h2> <p>Across our interviews, many participants discussed changing the way they presented themselves or changing the routes they took to school. They often focused on changing their own behaviour and <a href="https://policy.bristoluniversitypress.co.uk/the-right-amount-of-panic">made their lives smaller</a> in an attempt to avoid further harassment. </p> <p>For example, "I started walking the long way. I started just going through the main roads, avoiding the back streets, even though it was a longer walk to be extra safe."</p> <p>In the longer-term, participants commonly described feeling unsafe, hyper-vigilant, and distrustful of men in public spaces. </p> <h2>‘What if there’s a paedophile on the tram?’: school responses</h2> <p>Unfortunately, the view that victim-survivors are responsible for their own harassment was often reinforced by schools if harassment was reported. </p> <p>Numerous participants told us how they were reminded of school uniform policies (such as mandated length of skirts and dresses) when they went to teachers for help. </p> <p>One participant recounted an experience where her teacher asked, "Why would you wear your skirt like this [short]? Whose attention are you trying to get? […] what if there’s a paedophile when you’re on the tram home from school […] thinking ‘this is the best day of [my] life’."</p> <p>Others did not seek help from their teachers because of this focus on students’ appearance at school – they felt they would simply be blamed for what happened.</p> <p>These types of responses teach young people to think street harassment and other forms of gendered violence are their fault. It also tells them their bodies are sites of risk that need to be managed and contained to avoid harassment.</p> <h2>School uniform harassment is not ‘normal’</h2> <p>While schools and school-related contexts were often sites of harm for our participants, schools nonetheless have a vitally important role to play here. Harassment in school uniform should not be seen as a “normal” part of growing up. </p> <p>There is an urgent need to provide young people with a framework to understand their experiences.</p> <p>Educational efforts must challenge the idea that harassment must simply be endured. Instead, schools should help young people understand harassment as a form of violence, and offer safe and supportive spaces to talk with peers and adults about their experiences. This should be incorporated into existing sex and relationships education <a href="https://www.bodysafetyaustralia.com.au/">in an age-appropriate way</a>.</p> <p>Importantly, responses to harassment should never blame or implicate young people themselves. It’s time for outdated practices such as measuring school uniform length to be relegated to the past where they belong. </p> <p>In the words of one participant, “the length of my skirt is not influencing how much I learn”.</p> <p><strong><em>If this article has raised issues for you, or if you’re concerned about someone you know, call <a href="https://kidshelpline.com.au/">Kids Helpline</a> on 1800 55 1800 or <a href="https://www.1800respect.org.au/">1800RESPECT</a> on 1800 737 732.</em></strong></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/i-started-walking-the-long-way-many-young-women-first-experience-street-harassment-in-their-school-uniforms-202718" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Take a walk on the wild side with the Wildlife Photographer of the Year awards

<p>The People’s Choice Award winners of the 2022 Wildlife Photographer of the Year awards have been revealed, featuring stunning images of some of the world’s most majestic creatures. </p> <p>Competition for the coveted People’s Choice Award was fierce, with over 39,000 images submitted for consideration. 25 pictures were shortlisted from there, and a staggering 60,466 votes were received to crown the winner: German photographer Sascha Fonseca. </p> <p>Sascha’s image, titled “World of the snow leopard”, presents a snow leopard at sunset in Ladakh in northern India, with a breathtaking snow-covered mountain range backdrop. </p> <p>“Thick snow blankets the ground, but the big cat’s dense coat and furry footpads keep it warm,” the image was captioned. “Sascha captured this image during a three-year bait-free camera-trap project high up in the Indian Himalayas. He has always been fascinated by snow leopards, not only because of their incredible stealth but also because of their remote environment, making them one of the most difficult large cats to photograph in the wild.”</p> <p>The winning images, selected for their “artistic composition, technical innovation, and truthful interpretation of the natural world”, boast not only a winner, but four other highly commended finalists as well. </p> <p>"This year’s record number of votes illustrates how wildlife photography can engage and inspire audiences with the wonder of nature,” said Director of the Natural History Museum Douglas Gurr.</p> <p>The other finalist feature a leopard with some unexpected cargo titled “Holding on” by Igor Altuna, a moment of “Fox affection” in the snow by Brittany Crossman, a polar bear basking in the sun “Among the flowers” by Martin Gregus, and a magnificent “Portrait of Olobor” the lion by Maasai Mara. </p> <p>The Wildlife Photographer of the Year competition, produced by the Natural History Museum, provides amateur and professional photographers from around the world with a global platform for their work. 2022 marked the 58th year of competition, and the 59th is currently being judged, with the 2023 winners to be announced in October. </p> <p><em>All image credits: Wildlife Photographer of the Year awards</em></p>

"I loved him very much": Pink reveals heartbreaking inspiration behind hit track

<p>Multi award winning singer-songwriter Pink has opened up about the heartache that inspired her 2006 hit song ‘Who Knew’. </p> <p>The 43-year-old was chatting to fellow singer Kelly Clarkson on Kelly’s talk show when she made the tragic admission that ‘Who Knew’ is about the loss of two of her friends to drug overdose. </p> <p>“I lost several friends, unfortunately, to overdose,” she told Kelly, “and the second one was very, very, very close to me, and I loved him very much.” </p> <p>The singer was referring to her dear friend Sekou Harris, who died of a heroin overdose at just 14 years old.</p> <p>In a 2012 interview with <em>Entertainment Weekly</em>, Pink said of the song and its inspiration, “I always wanted to write a song for a friend of mine, Sekou Harris, who overdosed on heroin and died. And I never knew how because I didn’t want to force it and write some cheesy overdose song.”</p> <p>When Kelly mentioned that experiencing so much loss “sucks”, Pink countered that loss is unavoidable and that people “need music for that”. </p> <p>“I need music to help me through my feelings,” she said, “and I can numb down really easy.” </p> <p>She opened up about how the song has evolved over the years, and provided her comfort when faced with the deaths of those close to her heart. </p> <p>"But the thing that I love about the song now, after all these years, is that I never get tired of performing it, and it's taken on so many different meanings over the years,” she admitted, “it was about my grandmother at one point. It was about my dog.</p> <p>"I've lost people, so it's always sort of fresh in my heart." </p> <p>This isn’t the first time that Pink has been honest about her history with drugs. In her 2012 <em>EW </em>interview, the singer confessed that she understood addiction, as she “was a hardcore partier from 12 to 15. I was like a candy raver and I was on all the club drugs. Selling Ecstasy and crystal meth and Special K. I overdosed on Thanksgiving of ’95. And then I never took drugs again, ever.”</p> <p>In the same year, Pink told <em>Shape Magazine </em>that although she wasn’t hospitalised, she got the wake-up call she needed, and turned her attention to her wildly successful music career. </p> <p>Viewers of <em>The Kelly Clarkson Show</em> got a bonus look at that very career after the interview, with Pink and Kelly taking to the stage to perform a stunning duet of Pink’s ‘Who Knew’. </p> <p><em>Image: Getty</em></p> <p> </p>

How satellites, radar and drones are tracking meteorites and aiding Earth’s asteroid defence

<p>On July 31 2013 a <a href="https://cneos.jpl.nasa.gov/fireballs/" target="_blank" rel="noopener">constellation of US defence satellites</a> saw a streak of light over South Australia as a rock from outer space burned through Earth’s atmosphere on its way to crash into the ground below.</p> <p>The impact created an explosion equivalent to about 220 tonnes of TNT. More than 1,500km away, in Tasmania, the bang was heard by detectors normally used to listen for <a href="https://www.dfat.gov.au/international-relations/security/asno/Pages/australian-ims-stations" target="_blank" rel="noopener">extremely low-frequency sounds</a> from illegal tests of nuclear weapons.</p> <p>These were two excellent indications that there should be a patch of ground covered in meteorites somewhere north of Port Augusta. But how could we track them down?</p> <p>My colleagues and I who work on the <a href="https://dfn.gfo.rocks/" target="_blank" rel="noopener">Desert Fireball Network (DFN)</a>, which tracks incoming asteroids and <a href="https://dfn.gfo.rocks/meteorites.html" target="_blank" rel="noopener">the resulting meteorites</a>, had a couple of ideas: weather radar and drones.</p> <p><strong>Eyes in space</strong></p> <p>Finding meteorites is not an easy task. There is a network of high-quality ground-based sensors called the <a href="https://gfo.rocks/" target="_blank" rel="noopener">Global Fireball Observatory</a>, but it only covers about 1% of the planet.</p> <p>The <a href="https://cneos.jpl.nasa.gov/fireballs/" target="_blank" rel="noopener">US satellite data</a> published by NASA covers a much larger area than ground-based detectors, but it only picks up the biggest fireballs. What’s more, they <a href="https://academic.oup.com/mnras/article/483/4/5166/5256650" target="_blank" rel="noopener">don’t always give an accurate idea of the meteor’s trajectory</a>.</p> <p>So, to have any chance to find a meteorite from these data, you need a little outside help.</p> <p><strong>Weather radars</strong></p> <p>In 2019, Australia’s Bureau of Meteorology started making its weather radar data <a href="https://www.openradar.io/" target="_blank" rel="noopener">openly available</a> to researchers and the public. I saw this as an opportunity to complete the puzzle.</p> <p>I combed through the record of events from the Desert Fireball Network and NASA, and cross-matched them with nearby weather radars. Then I looked for unusual radar signatures that could indicate the presence of falling meteorites.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&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/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=334&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=334&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=334&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=420&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=420&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=420&amp;fit=crop&amp;dpr=3 2262w" alt="An annoyed aerial photo showing the locations of the Woomera radar station and the falling meteorites." /></a><figcaption><span class="caption">The Woomera weather radar station captured reflections from the falling meteorites.</span> <span class="attribution"><span class="source">Curtin University</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>And bingo, the 2013 event was not too far from the Woomera radar station.

It took scientists 100 years to track these eels to their breeding ground

<p>The life of a European eel isn’t an easy one. They’re critically endangered, must travel up to 10,000 km to get to their spawning point and then when they get there they <a href="https://en.wikipedia.org/wiki/Eel_life_history#European_eel" target="_blank" rel="noopener">probably die</a>.  </p> <p>But they’re also incredibly difficult to keep track of. In the 1920s a Danish biologist named Johannes Schmidt, discovered the <a href="https://en.wikipedia.org/wiki/Sargasso_Sea" target="_blank" rel="noopener">Sargasso Sea</a> – due east of North America – had eel larvae. He spent the next 20 years trying to confirm his finding. But in the century since, researchers have been unable to sample either eggs or spawning adults.</p> <p>Now, a team from Europe has published a paper in <a href="https://www.nature.com/articles/s41598-022-19248-8" target="_blank" rel="noopener"><em>Scientific Reports</em></a> that shows the first direct evidence of adult European eels migrating to the Sargasso Sea to breed. This provides vitally needed information on the life cycle of these slippery suckers.</p> <p>“The European Eel is critically endangered, so it is important that we solve the mystery surrounding their complete life-cycle to support efforts to protect the spawning area of this important species,” <a href="https://www.gov.uk/government/news/ancient-mystery-of-european-eel-migration-unravelled-to-help-combat-decline-of-critically-endangered-species" target="_blank" rel="noopener">says project lead Ros Wright from the UK Environment Agency.</a></p> <p>“This is the first time we’ve been able to track eels to the Sargasso Sea … Their journey will reveal information about eel migration that has never been known before.”</p> <p>The team attached satellite tags to 26 female eels that were in rivers in the Azores archipelago – an autonomous region of Portugal in the North Atlantic Ocean – and then waited.</p> <p>When tracking had been done before in areas within Europe, like the Baltic and North Sea, the migratory routes were tracked up to 5000 kilometres, but the tracking had not gone for long enough, and the eels were heading in the right direction, but never made it all the way to the Sargasso Sea.</p> <div class="newsletter-box"> <div id="wpcf7-f6-p219813-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> <p>“The data from the tags were used to identify migratory routes that extended up to 5000 km from release, and which suggested routes taken by eels migrating from different countries converge when passing the Azores,” <a href="https://www.nature.com/articles/s41598-022-19248-8" target="_blank" rel="noopener">the team wrote in their paper.</a></p> <p>“However, although eels were tracked for six months or more, their migration speed was insufficient to reach the Sargasso Sea for the first presumed spawning period after migration commenced, prompting the hypothesis that the spawning migration period of eels may extend to more than 18 months.”</p> <p>So, the team went directly to Azores to try and get the last leg of the journey, tracking 26 of the female eels with ‘X tags’. These collect data every two minutes and when the tag releases from the eel and bobs to the surface it then connects to the ARGOS satellite. Of course, not every single one worked. Only 23 tags communicated with the system; two became detached from the eels within a week. But the remainder provided a wealth of data to the team.</p> <p>Average migration speed was between 3 and 12 kilometres a day, and they were tracked from 40 days all the way to 366 days. Five of the eels ended up in within the Sargasso Sea boundaries while one eel made it all the way to the presumed breeding area Schmidt discovered those many years before.</p> <p>This isn’t the first time that eels have been tracked in this way. A study published last year, also in <a href="https://www.nature.com/articles/s41598-021-02325-9" target="_blank" rel="noopener"><em>Scientific Reports</em></a>, which Cosmos covered at the time, looked at the spawning migrations of the Australasian short-finned eel. They found that the eels travelled for five months, around 2,620 km from south-Eastern Australia, as far north as the Coral Sea in Northern Queensland.</p> <p>The researchers in the European eel case still have much to do. The eels didn’t move fast enough to be able to make it to the spawning period on time, which means we still don’t really understand the life cycle.  </p> <p>“Rather than make a rapid migration to spawn at the earliest opportunity, European eels may instead make a long, slow spawning migration at depth that conserves their energy and reduces mortality risk,” the team wrote.</p> <p>There’s also questions of what mechanisms the eels use to be able to correctly navigate to the Sargasso Sea. As usual in science, one answer has led to plenty more questions. </p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=219813&amp;title=It+took+scientists+100+years+to+track+these+eels+to+their+breeding+ground" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/nature/animals/european-eels-life-cycle-tracking-schmidt-sargasso-sea/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Jacinta Bowler.</em></p> <p><em>Image: Getty Images</em></p> </div>

The FBI tracked Aretha Franklin for 40 years - here’s why

<p dir="ltr">Until 2007, Aretha Franklin was tracked by the Federal Bureau of Investigation, with her bumper 270-page file recently obtained by <em><a href="https://rollingstoneindia.com/aretha-franklin-was-tracked-by-the-fbi-for-40-years-heres-whats-in-her-file/" target="_blank" rel="noopener">Rolling Stone</a></em>.</p> <p dir="ltr">The Queen of Soul, who passed away in 2018 aged 76, was subjected to false phone calls and surveillance, as well as having her inner circle infiltrated by FBI sources, according to the outlet.</p> <p dir="ltr">Franklin’s file, first requested via the Freedom of Information Act shortly after her death, is reportedly filled with phrases such as “Black extremists”, “pro-communist”, “hate America”, “radical”, “racial violence”, and “militant Black power”.</p> <p dir="ltr">It also contained plenty of suspicion about the singer, her work, and the other artists and activists she associated with, as the FBI tried and failed to connect the Respect singer to the Black Liberation Army and other “radical” movements.</p> <p dir="ltr">According to the documents, Franklin’s civil rights work and association with activists including Martin Luther King Jr and Angela Davies, became a focus for the FBI, with agents tracking her addresses, phone numbers and activities.</p> <p dir="ltr">The singer’s son, Kecalf, told the <em>Rolling Stone</em> he was unsure whether Franklin knew she was under surveillance but said it was a “waste of time” for the FBI to follow her “every move” for so many years after failing to connect her to radical movements of any kind.</p> <p dir="ltr">"I'm not really sure if my mother was aware that she was being targeted by the FBI and followed. I do know that she had absolutely nothing to hide though…” he said.</p> <p dir="ltr">"It does make me feel a certain way knowing the FBI had her targeted and wanted to know her every move.</p> <p dir="ltr">"But at the same time knowing my mother and the way she ran her business I know she had nothing to hide so they wouldn't have found anything and were wasting their time. As you see…they found nothing at all."</p> <p dir="ltr">The documents obtained by <em>Rolling Stone</em>, which include some newly-declassified files and others that are heavily redacted, include a 1968 report discussing funeral plans for Martin Luther King Jr which described it as a “racial situation”.</p> <p dir="ltr">“Sammy Davis Jr., Aretha Franklin…of this group, some have supported militant Black power concept…[performance at MLK memorial by these prominent entertainers] would provide emotional spark which could ignite racial disturbance in this area,” it reads.</p> <p dir="ltr">The FBI also included files “just in case”, such as her 1971 contract with Atlantic Records to attempt to connect the <em>Blues Brothers</em> star’s business dealings to the Black Panther Party.</p> <p dir="ltr">Letters and reports of death threats were among the collection of documents as well, including one from a man threatening to kill her and her family and another extortion attempt against her.</p> <p dir="ltr">With some documents indicating that there are additional materials in the FBI’s possession that haven’t been released, <em>Rolling Stone</em> requested these records be made available.</p> <p dir="ltr">The FBI has yet to comment on the report.</p> <p><span id="docs-internal-guid-b53d2a36-7fff-78ce-80b9-125e7216fcbd"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>
