“Hypocrite”: Hughesy's on-air clash with Greens leader

<p>Dave “Hughesy” Hughes had a fiery debate with Australian Greens Leader Adam Bandt about veganism on-air on<em> </em>The Fox’s <em>Fifi, Fev & Nick</em>. </p> <p>Before Bandt appeared on the show, a clip played of Hughesy, who is a vegan, calling for the leader to "quit the party" after learning the Greens leader wasn't a vegan. </p> <p>He questioned how Bandt could advocate for climate action without adopting a plant-based lifestyle, and the Greens leader was brought onto the show to explain his stance. </p> <p>“So you are not a vegan?” Hughesy asked the politician. </p> <p>“I’m not….” replied Bandt. “I applaud those who are, I applaud those who have made the shift. I’ve been thinking about it …”</p> <p>Hughesy then loudly interjected “ … URGH, THINKING ABOUT IT?”</p> <p>The Greens leader replied: “I don’t have a good drop-dead reason, but I’ve been thinking about it, and I can probably give you three justifications for it.</p> <p>"Firstly, we’ve made big changes at home and basically only eat meat for special occasions, the rest of the time we’re vegan or vegetarian at home.”</p> <p>“…. THERE’S ONE WAY, ADAM, THERE’S ONE WAY …” the presenter yelled in response. </p> <p>Hughesy's co-star Fev then tried to make light of the situation and asked him: “What are you doing Dave?"</p> <p>"Adam is doing the version of Leonardo DiCaprio and his private jet flying around the world while banging on about climate change, but you flew to Brisbane on the weekend,” he continued suggesting that Hughesy too was being a hypocrite by getting on a flight recently. </p> <p>“But I don’t bang on about it,” exclaimed Hughesy.</p> <p>“Adam is the leader of the Greens … it’s hypocritical! C’mon, you can do it, Adam, you can become a vegan! Be the change you want to see in the world, buddy!”</p> <p>Hughesy adopted the vegan lifestyle for his own health, but he has previously revealed that it comes with its challenges and his family were also not that enthusiastic about the change. </p> <p><em>Image: news.com.au/ Fifi, Fev & Nick</em></p>

I’m due for a cervical cancer screening. What can I expect? Can I do it myself? And what happened to Pap smears?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/karen-canfell-22668">Karen Canfell</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/deborah-bateson-16105">Deborah Bateson</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/megan-smith-131901">Megan Smith</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Cervical screening in Australia has <a href="https://pubmed.ncbi.nlm.nih.gov/34499374/">changed</a> over the past seven years. The test has changed, and women (and people with a cervix) now have much more choice and control. Here’s why – and what you can expect if you’re aged 25 to 74 and are <a href="https://www.health.gov.au/our-work/national-cervical-screening-program">due for a test</a>.</p> <h2>When and why did the test change?</h2> <p>In 2017, Australia became one of the first two countries to transition from Pap smears to tests for the presence of the human papillomavirus (HPV).</p> <p>HPV causes virtually all cervical cancers, so testing for the presence of this virus is a very good indicator of a person’s current and future risk of the disease.</p> <p>This contrasts with the older Pap smear technology, which involved inspection of cells every two years for the changes resulting from HPV infection.</p> <p>The change to screening was supported by a very large body of <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(13)62218-7/abstract">international</a> and <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002388">Australian</a> data showing primary testing for HPV is more accurate than Pap smears.</p> <p>Women and people with a cervix who do not have HPV detected on their test are at a very low risk of developing cervical cancer over the next five years, or even longer. This was the basis for lengthening the screening interval when HPV screening was introduced.</p> <p>Australia now <a href="https://www.health.gov.au/our-work/national-cervical-screening-program">recommends</a> five-yearly HPV screening, starting at age 25 up to the age of 74 for eligible people, whether or not they have been vaccinated against HPV. Many other countries are following suit to transition to HPV screening.</p> <p>All established screening tests – which are conducted in people without any symptoms – are associated with health benefits but also with some harms. These can include the psychological and clinical consequences of receiving a “positive” screening result, which needs to be investigated further.</p> <p>However, recent World Health Organization (WHO) <a href="https://www.nejm.org/doi/full/10.1056/NEJMsr2030640">reviews of the evidence</a> have found:</p> <ul> <li>HPV is a more effective screening test than Pap smears or any other method</li> <li>it substantially reduces incidence and death rates from cervical cancer</li> <li>it is the method of cervical screening that has the <a href="https://www.nature.com/articles/s41591-023-02600-4">best balance</a> of benefits to harms.</li> </ul> <p>As a consequence, the WHO now unequivocally <a href="https://www.who.int/publications/i/item/9789240030824">recommends</a> HPV screening as the best-practice method.</p> <h2>Now you can collect your own sample</h2> <p>One of the major benefits of switching to HPV screening is it opened the door for a person being able to <a href="https://www.health.gov.au/self-collection-for-the-cervical-screening-test">collect their own sample</a> (which was impossible with the Pap smear). If HPV is present, it can be detected in the vagina rather than having to directly sample the cervix.</p> <p>In 2022, Australia became one of the <a href="https://www.health.gov.au/ministers/the-hon-greg-hunt-mp/media/landmark-changes-improving-access-to-life-saving-cervical-screenings">first countries</a> in the world to introduce a universal option to choose self-collection within a major national-level screening program. This means people eligible for screening, under the guidance of a primary care practitioner, can now choose to collect their own vaginal sample, in privacy, using a simple swab.</p> <p>By the end of 2023, <a href="https://www.ncsr.gov.au/about-us/news-and-media/self-collection-for-cervical-screening--at-an-all-time-high.html">27% of people</a> were choosing to take the test this way, but this is on an upward trajectory and is likely to increase further, with an <a href="https://acpcc.org.au/self-collection-campaign/">awareness campaign</a> due to start next month.</p> <h2>So what happens when I have a test?</h2> <p>You’ll receive an invitation from the <a href="https://www.ncsr.gov.au/information-for-participants/participant-forms-and-guides.html#cervical-forms">National Cancer Screening Register</a> to attend your first screen when you turn 25. If you’re older, you’ll receive reminders when you are due for your next test. You will be invited to visit your GP or community health service for the test.</p> <p>You should be asked whether you would prefer to have a clinician collect the test or whether you would prefer to take the sample yourself.</p> <p>There’s no right or wrong way. The accuracy of testing has been <a href="https://www.bmj.com/content/363/bmj.k4823">shown</a> to be equivalent for clinician or self-collected sampling. This is a matter of choice.</p> <p>If the clinician does the test, they will undertake a pelvic examination with a speculum inserted into the vagina. This enables the doctor or nurse to view the cervix and take a sample.</p> <p>If you are interested in the self-collection option, check whether the practice is offering it when making an appointment.</p> <p>If you opt for self-collection, you’ll be able to do so in private. You’ll be given a swab (which looks like a COVID test swab with a longer stem), and you’ll be given instructions about how to insert and rotate the swab in the vagina to take the sample. It takes only a few minutes.</p> <h2>What does it mean if my test detects HPV?</h2> <p>If your test detects HPV, this means you have an HPV infection. These are very common and by itself doesn’t mean you have cancer, or even pre-cancer (which involves changes to cervical cells that make them more likely to develop into cancer over time).</p> <p>It does mean, however, that you are at higher risk of having a pre-cancer, or developing one in future, and that you will benefit from further follow-up or diagnostic testing. Your doctor or nurse will <a href="https://www.cancer.org.au/clinical-guidelines/cervical-cancer/cervical-cancer-screening">guide you</a> on the next steps in line with national guidelines.</p> <p>If you require a diagnostic examination, this will involve a procedure called colposcopy, where the cervix is closely examined by a gynaecologist or other specially trained healthcare practitioner, and a small sample may be taken for detailed examination of the cells.</p> <p>If you have a pre-cancer, you can be treated simply and quickly, usually without needing to be admitted to hospital. Treatment involves ablating or removing a small area of the cervix. This treatment will drastically reduce your risk of ever developing cervical cancer.</p> <h2>What does this mean for cervical cancer rates?</h2> <p>Cervical screening for HPV is a very effective method of preventing cervical cancer. Because of Australia’s HPV screening, combined with HPV vaccination in younger people, Australia is <a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(18)30183-X/fulltext">expected</a> to achieve such low rates of cervical cancer by 2035 that it will be considered eliminated.</p> <p>Last year, the government launched a <a href="https://www.health.gov.au/sites/default/files/2023-11/national-strategy-for-the-elimination-of-cervical-cancer-in-australia.pdf">national strategy for cervical cancer elimination</a> which provides key recommendations for eliminating cervical cancer, and for doing so equitably in all groups of women and people with a cervix.</p> <p>One of the best things you can do to protect yourself is to have your cervical screening test when you become eligible, whether or not you have been vaccinated against HPV.</p> <p><em>Marion Saville, a pathologist and Executive Director at the Australian Centre for the Prevention of Cervical Cancer, co-authored this article.</em><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/229495/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/karen-canfell-22668"><em>Karen Canfell</em></a><em>, Professor & Director, Daffodil Centre, A Joint Venture with Cancer Council NSW, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/deborah-bateson-16105">Deborah Bateson</a>, Professor of Practice, The Daffodil Centre, a joint venture with Cancer Council NSW, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/megan-smith-131901">Megan Smith</a>, Principal Research Fellow, The Daffodil Centre, a joint venture with Cancer Council NSW, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Craig McLachlan set to return to Aussie screens

<p>Six years after being "crucified" in the public eye, Craig McLachlan is set to make his return to Aussie screens. </p> <p>The 58-year-old was unexpectedly approached by movie producers who asked him to star in a new feature film, almost seven years since his last on-screen project. </p> <p>Speaking exclusively with <a href="https://www.dailymail.co.uk/tvshowbiz/article-13716307/Craig-McLachlan-Neighbours-Rocky-Horror-comeback-movie.html" target="_blank" rel="noopener"><em>Daily Mail Australia</em></a>, McLachlan said his return to the big screen had helped him deal with the "poisonous hate" that had eaten away at him since he was hounded out of the industry six years ago.</p> <p>In 2018, McLachlan was forced to quit his leading role as Frank-N-Furter in a 2018 production of <em>The Rocky Horror Picture Show</em> after three of his former female co-stars accused him of serious inappropriate behaviour while performing alongside him four years earlier.</p> <p>The former <em>Neighbours</em> star was charged with 13 offences of assault and indecent assault after Victoria Police investigated the allegations but he was ultimately acquitted on all counts following a four-week trial in December 2020.</p> <p>Now, McLachlan candidly admitted that he was unlikely to ever find it in his heart to forgive the former co-stars who accused him of sexual harassment, and that he still blames them for "ruining" his life.</p> <p>"Here's the thing: hate is a poisonous thing. You have to get rid of the hate – and I've done that," he said.</p> <p>"Forgiveness is a different story. That’s hard s**t to do."</p> <p>McLachlan said he had "fallen out of love" with show business after his "public crucifixion" but decided to accept the role after discussing the opportunity with long-term partner Vanessa Scammell. </p> <p>"I only just went and met with the producers and the director last week and agreed to do it," he said.</p> <p>"I wasn't expecting to be approached about a return to acting… and certainly not about signing on to do a film – it was a complete surprise."</p> <p>"But it's a fantastic Australian production and Vanessa and I sat down and discussed it - and talked about whether it was the right thing for both of us. When you've had your life destroyed like mine has been, you need to take a little time to rest and recalibrate."</p> <p>"I haven't rushed into anything. I needed to think about what we wanted to do and what - physically - I could do. And we decided this was the right thing for us."</p> <p>McLachlan, who has been in therapy since the allegations first came to light, said he was grateful for his partner's support during the difficult few years, and is happy to be making his return to screen with a new lease on life. </p> <p>"When the s**t kicks off in the media, people start running for cover and they're afraid to put their heads up to support you publicly because they're worried about them getting chopped off," he said. </p> <p>"I'll be forever grateful to those people who did stand by me – people like Vanessa – who helped me keep going."</p> <p>"Irrespective of what anyone has ever said or alleged about me, nothing I do or say would ever be done intentionally to make anyone else feel uncomfortable. I know that’s not who I am."</p> <p>"But as for forgiveness? Ask me again about forgiveness a little further down the track."</p> <p><em>Image credits: Getty Images </em></p>

Does screen use really impact our thinking skills? Our analysis suggests it could

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michoel-moshel-1433565">Michoel Moshel</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/jennifer-batchelor-1485101">Jennifer Batchelor</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/joanne-bennett-1485102">Joanne Bennett</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>, and <a href="https://theconversation.com/profiles/wayne-warburton-402810">Wayne Warburton</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p>Screens have become seamlessly integrated into our daily lives, serving as indispensable tools for work, education and leisure. But while they enrich our lives in countless ways, we often fail to consider the potential impact of screen time on our cognitive abilities.</p> <p>In a <a href="https://link.springer.com/article/10.1007/s11065-023-09612-4">new meta-analysis</a> of dozens of earlier studies, we’ve found a clear link between disordered screen use and lower cognitive functioning.</p> <p>The findings suggest we should exercise caution before advocating for more screen time, and before introducing screens into even more aspects of daily life.</p> <h2>Young people’s screen time is increasing</h2> <p>In 2020, a UNSW Gonski Institute for Education report <a href="https://www.gie.unsw.edu.au/sites/default/files/documents/UNSW%20GIE%20GUD%20Phase%201%20Technical%20Report%20MAR20%20v2.pdf">noted a concerning statistic</a>: about 84% of Australian educators believe digital technologies are distracting in a learning environment.</p> <p>And according to the ABC, a recent Beyond Blue <a href="https://www.abc.net.au/news/2023-09-18/mental-health-depression-anxiety-support-coming-for-schools/102831464">survey</a> of Australian teachers identified excessive screen time as the second-most significant challenge for young people, just behind mental health issues.</p> <p>Despite mounting concerns, more than half of Australian schools have embraced a “<a href="https://www.linewize.io/anz/blog/the-rise-of-byod-in-australian-schools">bring your own device</a>” policy. Students are spending more time online than <a href="https://read.oecd-ilibrary.org/education/students-computers-and-learning_9789264239555-en#page46">ever before</a> and starting at increasingly younger ages. A 2021 report by <a href="https://www.commonsensemedia.org/sites/default/files/research/report/8-18-census-integrated-report-final-web_0.pdf">Common Sense Media</a> estimated tweens spend an average of 5 hours and 33 minutes using screen-based entertainment each day, while teenagers devote a whopping 8 hours and 39 minutes.</p> <p>A surge in screen use has led to some individuals, including children, adolescents and adults, developing screen-related addictions. One example is gaming disorder, for which <a href="https://journals.sagepub.com/doi/full/10.1177/0004867420962851">2–3% of people</a> meet the criteria.</p> <h2>What is ‘disordered screen use’?</h2> <p>The impact of screens on our cognitive abilities – that is, our thinking skills such as attention, memory, language and problem-solving – has sparked much debate.</p> <p>On one hand, some researchers and reporters claim screen use can have negative effects, such as <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-022-12701-3">health problems</a>, shortened attention <a href="https://time.com/3858309/attention-spans-goldfish/">spans</a> and hindered <a href="https://www.researchgate.net/publication/312489265_The_relationship_between_television_exposure_and_children's_cognition_and_behaviour_A_systematic_review">development</a>.</p> <p>On the other, schools are <a href="https://www.smh.com.au/education/tech-takeover-classrooms-crowded-with-digital-devices-20200125-p53ul1.html">increasingly adopting</a> technology to boost student engagement. Tech companies are also marketing their products as tools to help you enhance your problem-solving and memory skills.</p> <p>Our <a href="https://link.springer.com/article/10.1007/s11065-023-09612-4">recent study</a> sought to understand the potential cognitive consequences of “disordered screen-related behaviours”. This is a broad category of problematic behaviours that may include screen dependency, and persisting with screen use even when it’s harmful.</p> <p>We conducted a meta-analysis of 34 studies that explored various forms of screen use (including gaming, internet browsing, smartphone use and social media use) and compared the cognitive performance of individuals with disordered screen use to those without it.</p> <p>Our findings paint a concerning picture.</p> <h2>Differences in cognitive function</h2> <p>Across these rigorously peer-reviewed studies, individuals with disordered screen use consistently demonstrated significantly poorer cognitive performance compared to others.</p> <p>The most affected cognitive domain was attention, and specifically sustained attention, which is the ability to maintain focus on an unchanging stimulus for an extended period.</p> <p>The second-most notable difference was in their “executive functioning” – particularly in impulse control, which is the ability to control one’s automatic responses.</p> <p>Interestingly, the type of screen activity didn’t make a difference in the results. The trend also wasn’t confined to children, but was observed across all age groups.</p> <h2>Two ways to interpret the results</h2> <p>Why do people with disordered screen-related behaviours have poorer cognitive functioning?</p> <p>The first explanation is that disordered screen use actually leads to poorer cognitive function, including poorer attention skills (but we’ll need more experimental and longitudinal studies to establish causality).</p> <p>If this is the case, it may be the result of being constantly bombarded by algorithms and features designed to capture our attention. By diverting our focus outward, screen use may weaken one’s intrinsic ability to concentrate over time.</p> <p>Crucially, impaired attention also <a href="https://akjournals.com/view/journals/2006/10/1/article-p77.xml">makes it harder to disengage</a> from addictive behaviours, and would therefore make it harder to recognise when screen use has become a problem.</p> <p>The second explanation is that people who already have poorer cognitive functioning (such as less inhibitory control) are more likely to engage in disordered screen use.</p> <p>This could be a result of the plethora of addictive cues designed to keep us glued to our screens. Being bombarded by these could make it harder to <a href="https://akjournals.com/view/journals/2006/9/4/article-p990.xml">pull the brakes</a> on screen use.</p> <p>Although the literature doesn’t seem to favour this explanation – and does seem to suggest that cognitive functioning is impaired as a result of disordered screen use – it’s still a possibility we can’t rule out.</p> <p>Attention is the bedrock of everyday tasks. People with weakened attention may struggle to keep up in less stimulating environments, such as a static workplace or classroom. They may find themselves turning to a screen as a result.</p> <p>Similarly, people with less inhibitory control would also find it more challenging to moderate their screen use. This could be what drives them towards problematic screen-related behaviours in the first place.</p> <h2>Who should shoulder the responsibility?</h2> <p>Research indicates people with impaired cognitive functioning usually aren’t as well equipped to moderate their own screen time.</p> <p>Many users with disordered screen use are <a href="https://www.sciencedirect.com/science/article/pii/S0747563220302326?casa_token=BQv_N_MFffYAAAAA:AsGkAfdwXjCZHJB463G40Mx-ckS2Q1c8jSOn2SWR_9iW64eWaQsru1IJAZBDCgSPXwhZ3Qwl">young</a>, with mainly males engaging in internet gaming and mainly females engaging in social media use. Neurodiverse people are <a href="https://www.mdpi.com/1660-4601/19/9/5587">also at greater risk</a>.</p> <p>Tech companies are driven by the goal of <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">capturing our attention</a>. For instance, Netflix chief executive Reed Hastings acknowledged the company’s <a href="https://www.theguardian.com/technology/2017/apr/18/netflix-competitor-sleep-uber-facebook">most formidable competitor was sleep</a>.</p> <p>At the same time, researchers find themselves struggling to keep up with the pace of technological innovation. A potential path forward is to encourage open-access data policies from tech companies, so researchers can delve deeper into the study of screen use and its effect on individuals. <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/216828/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michoel-moshel-1433565">Michoel Moshel</a>, PhD/Masters Clinical Neuropsychology Candidate, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/jennifer-batchelor-1485101">Jennifer Batchelor</a>, Associate Professor, School of Psychological Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/joanne-bennett-1485102">Joanne Bennett</a>, Lecturer, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>, and <a href="https://theconversation.com/profiles/wayne-warburton-402810">Wayne Warburton</a>, Associate Professor, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Breast cancer screening in Australia may change. Here’s what we know so far

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/brooke-nickel-200747">Brooke Nickel</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/katy-bell-134554">Katy Bell</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>The way women are screened for breast cancer in Australia may <a href="https://www.cancer.org.au/about-us/policy-and-advocacy/early-detection/breast-cancer/rosa/key-findings">change</a>.</p> <p>There’s international debate on the <a href="https://www.bmj.com/content/385/bmj.q1353">age</a> women should be invited for screening. But an even larger change being considered worldwide is whether to screen women at <a href="https://www.nature.com/articles/s41416-021-01550-3">high and low risk</a> of breast cancer differently.</p> <p>But what such a “risk-based” approach to screening might look like in Australia is not yet clear.</p> <p>Here’s why researchers and public health officials are floating a change to breast cancer screening in Australia, and what any changes might mean.</p> <h2>Why breast cancer screening may need to change</h2> <p>Mass screening (known as population-based screening) for breast cancer was introduced in Australia and many other developed countries in the 1980s and 90s.</p> <p>This was based on <a href="https://pubmed.ncbi.nlm.nih.gov/26756588/">robust research</a> that found early detection and treatment of cancers before there were symptoms prevented some women from dying from breast cancer.</p> <p>These programs offer regular breast cancer screening to women within a specific age group. For example, <a href="https://www.aihw.gov.au/reports/cancer-screening/national-cancer-screening-programs-participation/contents/breastscreen-australia">in Australia</a>, women aged 40-74 years can have free mammograms (x-rays of the breasts) every two years. The BreastScreen program sends invitations for screening to those aged 50-74.</p> <p>However, evidence has been mounting that mammography screening could be inadvertently causing <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)61611-0/abstract">harm</a> for some women.</p> <p>For some, screening causes a false alarm that may cause anxiety, and unnecessary tests and procedures. Even though these tests rule out cancer, these women may remain anxious and perceive something is wrong <a href="https://bmjopen.bmj.com/content/13/4/e072188">for many years</a>.</p> <p>A more insidious harm is <a href="https://theconversation.com/five-warning-signs-of-overdiagnosis-110895">overdiagnosis</a>, where screening detects a non-growing or slow-growing lesion that looks like “cancer” under the microscope, but would not have progressed or caused harm if it had been left alone. This means some women are having unnecessary surgery, radiotherapy and hormone therapy that will not benefit them, but may harm.</p> <p>Although trials have shown screening reduces the risk of dying from breast cancer, questions are being raised about how much it <a href="https://www.bmj.com/content/352/bmj.h6080.abstract">saves lives overall</a>. That is, it’s uncertain how much the reduced risk of dying from breast cancer translates into improvements in a woman’s overall survival.</p> <h2>How about better targeting women?</h2> <p>One idea is to target screening to those most likely to benefit. Under such a “<a href="https://www.nature.com/articles/s41416-021-01550-3">risk-based</a>” approach, a women’s personal risk of breast cancer is estimated. This may be based on her age and many other factors that may include breast density, family history of breast cancer, body-mass index, genetics, age she started and stopped her periods, and the number of children she’s had.</p> <p>Women who are at higher risk would be recommended to start screening at a younger age and to screen more frequently or to use different, more sensitive, imaging tests. Women at lower risk would be recommended to start later and to screen less often.</p> <p>The idea of this more “precise” approach to screening is to direct efforts and resources towards the smaller number of women most likely to benefit from screening via the early detection of cancer.</p> <p>At the same time, this approach would reduce the risk of harm from false positives (detection of an anomaly but no cancer is present) and overdiagnosis (detection of a non-growing or slow-growing cancer) for the larger number of women who are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6230256/">unlikely to benefit</a>.</p> <p>On face value this sounds like a good idea, and could be a favourable change for breast cancer screening.</p> <h2>But there’s much we don’t know</h2> <p>However, it’s uncertain how this would play out in practice. For one thing, someone’s future risk of a cancer diagnosis includes the risk of detecting both <a href="https://www.acpjournals.org/doi/10.7326/m17-2792">overdiagnosed cancers</a> as well as potentially lethal ones. This is proving to be a problem in risk-based screening for <a href="https://www.nature.com/articles/s41698-022-00266-8">prostate cancer</a>, another cancer prone to overdiagnosis.</p> <p>Ideally, we’d want to predict someone’s risk of <a href="https://www.thelancet.com/journals/landig/article/PIIS2589-7500(23)00113-9/fulltext">potentially lethal cancers</a> as these are the ones we want to catch early.</p> <p>It is also still uncertain how many women found to be at <a href="https://pubmed.ncbi.nlm.nih.gov/31701797/">low risk</a> will accept a recommendation for <a href="https://pubmed.ncbi.nlm.nih.gov/23092125/">less screening</a>.</p> <p>These uncertainties mean we need robust evidence the benefits outweigh the harms for Australian women before we make changes to the breast cancer screening program.</p> <p>There are several international <a href="https://www.nature.com/articles/s41416-021-01550-3">randomised controlled trials</a> (the gold standard for research) under way to evaluate the effectiveness of risk-based screening compared to current practice. So it may be prudent to wait for their findings before making changes to policy or practice.</p> <p>Even if such trials did give us robust evidence, there are still a number of issues to address before implementing a risk-based approach.</p> <p>One key issue is having enough staff to run the program, including people with the skills and time to discuss with women any concerns they have about their calculated risk.</p> <h2>How about breast density?</h2> <p>Women with dense breasts are at <a href="https://www.sciencedirect.com/science/article/pii/S0960977622001618#:%7E:text=Mammographic%20density%20is%20a%20well,increased%20risk%20of%20breast%20cancer.">higher risk of breast cancer</a>. So notifying women about their breast density has been proposed as a “first step” on the pathway to risk-based screening. However, this ignores the many other factors that determine a woman’s risk of breast cancer.</p> <p>Legislation in the <a href="https://www.fda.gov/radiation-emitting-products/mammography-quality-standards-act-and-program">United States</a> and changes in some <a href="https://australianbreastcancer.org.au/news-stories/latest-news/breast-density-reporting-at-all-sa-clinics/">Australian states</a> mean some women are already being notified about their breast density. The idea is to enhance their knowledge about their breast cancer risk so they can make informed decisions about future screening.</p> <p>But this has happened before we know what the best options are for such women. An <a href="https://www.mja.com.au/journal/2023/219/9/psychosocial-outcomes-and-health-service-use-after-notifying-women-participating">ongoing Australian trial</a> is investigating the effects that breast density notification has on individual women and the health system.</p> <h2>What next?</h2> <p>Robust evidence and careful planning are needed before risk-based screening or other changes are made to Australia’s breast cancer screening program.</p> <p>Where changes are made, there needs to be early evaluation of both the <a href="https://www.bmj.com/content/350/bmj.h1566.abstract">benefits and harms</a>.

Eating leafy greens could be better for oral health than using mouthwash

Aussie grandma and former Greens candidate jailed in Japan claims she was scammed

<p>Donna Nelson, a 57-year-old Perth grandmother, has found herself entangled in a nightmarish situation in a Japanese prison, accused of a crime she vehemently denies.</p> <p>Nelson, an Aboriginal health advocate and former Greens candidate, has been incarcerated for nearly a year without a trial date set, facing allegations of attempting to smuggle two kilograms of meth into Japan. However, her plight is not as straightforward as it may seem, and her family and legal team are tirelessly fighting to clear her name.</p> <p>The ordeal began on January 4, when Nelson was arrested at Narita Airport in Tokyo. Authorities claimed to have discovered drugs concealed within a false compartment in her luggage. According to the prosecution, a customs officer suspected her of acting suspiciously. But the narrative has taken a complex turn as Nelson's defence team unveiled a shocking revelation: she alleges she was deceived and manipulated by a Nigerian scammer who had groomed her for two years.</p> <p>Since her arrest, Nelson has been confined to Chibu prison, located an hour outside Tokyo. Her living conditions are appalling; she spends 23 hours a day isolated in her cell, showers are allowed only every three days, and communication with other inmates and visitors is strictly prohibited. This form of treatment is a reflection of Japan's infamous "hostage justice" strategy, aimed at coercing confessions from detainees.</p> <p>The only individuals granted access to Nelson are her lawyers, Australian embassy representatives, and a pastor. Legal representatives have identified a significant issue with translation throughout the case, and it could very well hinge on an inaccurate translation by the customs officer at the time of her arrest.</p> <p>Rie Nishida from Shinjuku International Law Firm, one of Nelson's lawyers, explained, "The main evidence from the prosecution is mainly a customs officer who said she acted suspiciously. There's a lot of mistranslation that's also the difficulty in this case."</p> <p>This mistranslation issue is not trivial; it extends to the messages exchanged between Nelson and the man she believed she had a romantic connection with, who ultimately turned out to be a scammer.</p> <p>Matthew Owens, another member of the legal team and a translator for the case, noted, "Some of them were completely wrongly translated, so we had to re-translate those messages and submit them back to the prosecutor."</p> <p>Nelson remains steadfast in her conviction that she is innocent of the accusations against her. Her lawyer, Owens, relayed her message, saying, "Donna wants to say that she is going to be able to prove her innocence, she's 100 per cent confident of that, and she wants everyone in Australia and the world to know she is innocent."</p> <p>If found guilty, Nelson could face a harrowing 20-year sentence in a Japanese prison, a terrifying prospect for both her and her family. Her five daughters and grandchildren are distraught, but they are not giving up the fight to prove her innocence. They believe they have evidence to substantiate the claim that she was scammed and unjustly accused.</p> <p><em>Image: Australian Greens</em></p>

Why does my hair turn green from the swimming pool?

<p><em><a href="https://theconversation.com/profiles/magdalena-wajrak-1432339">Magdalena Wajrak</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>If you are a blonde like me and enjoy laps in a swimming pool, you may have noticed your hair acquires a green tint after frequent swims in chlorinated water.</p> <p>This happens to both bleached and natural blondes. In fact, the green tinge happens to everyone, but it’s less visible on dark hair and those whose hair isn’t damaged by chemical treatments such as bleaching.</p> <p>But what exactly causes this green discoloration, and what can we do about it? Most of us blame the chlorine in the pool water. However, although chlorine does play a part, it is not the main culprit.</p> <h2>Which chemicals in the pool turn the hair green?</h2> <p>The element to blame for the green staining of hair is copper.</p> <p>The main source of copper is copper sulfate (CuSO₄), a compound added to swimming pools to prevent the growth of algae. <a href="https://www.sciencedirect.com/science/article/pii/S1568988320301803?via%3Dihub">Contact with algae</a> can cause skin irritation and respiratory issues, and ingesting water with algae can lead to serious gastrointestinal problems. Only a small amount (around 0.5mg per litre or 0.5 parts per million) of copper sulfate is needed to prevent algal growth.</p> <p>However, copper can also enter swimming pools through the corrosion of water pipes, so concentrations may be higher in some pools.</p> <p>Copper sulfate crystals are greenish-blue in colour. So, when hair comes into contact with copper ions – a positively charged variant of a copper atom with extra electrons – those ions get absorbed by the hair and cause the greenish hue.</p> <p>Scientists were fascinated by the green “pool hair” phenomenon as far back as the 1970s, so we actually have research data on copper being the cause.</p> <p>One very <a href="https://jamanetwork.com/journals/jamadermatology/article-abstract/538197">interesting study in 1978</a> performed experiments by immersing hair samples into water containing different concentrations of copper ions, chlorine and various pH values (neutral and basic). Their results showed hair exposed to free copper ions does turn green.</p> <p>Furthermore, when hair is oxidised (meaning electrons are removed from the hair proteins) by chlorine, it actually damages the hair, enhancing the absorption of copper ions. Hair submerged in water with chlorine but without copper ions did not turn green. Meanwhile, hair exposed to water with only copper ions and no chlorine still formed a green colour.</p> <p>Hence, chlorine by itself does not play a role in causing the green hue we see in “pool hair”, but it does exacerbate it.</p> <h2>So, how does copper get into the hair?</h2> <p><a href="https://doi.org/10.1007/978-1-4684-0943-7_24">Other research teams</a> have conducted <a href="https://doi.org/10.1071/ch9682437">more extensive studies</a>, using sophisticated instruments, such as scanning electron microscopy, to examine how exactly copper ions attach to the hair.</p> <p>Our hair is predominantly composed of protein called keratin. Keratin is classified as a “structural fibrous protein”, meaning it has an elongated, sheet-like structure.</p> <p>The keratin structure is composed of various <a href="https://chem.libretexts.org/Courses/University_of_Kentucky/UK%3A_CHE_103_-_Chemistry_for_Allied_Health_(Soult)/Chapters/Chapter_4%3A_Structure_and_Function/4.4%3A_Functional_Groups">chemical groups</a> (types of atom groupings with similar properties), such as carboxyl groups, amino groups and disulfide groups. Copper ions have the ability to form bonds with these groups, forming a copper-keratin complex. This complex remains in the hair, causing it to appear green.</p> <p>Interestingly, the most recent study <a href="https://doi.org/10.32657/10356/142466">conducted in 2020</a>, showed copper ions mainly bind to the disulfide groups. This study also found other metal ions such as zinc, lead, chromium and mercury also bind to hair in the same way. This is very useful in <a href="https://theconversation.com/forensic-breakthrough-study-suggests-humans-can-be-identified-by-the-proteins-in-their-hair-65051">forensic analysis</a>, for example, because forensic scientists can analyse hair samples to determine if a person has been exposed to a particular metal.</p> <p>Light-coloured hair already has the most visible green discoloration, but research has shown that damaged hair, caused by bleaching, straightening, or exposure to sun, is the <a href="https://pubmed.ncbi.nlm.nih.gov/19586601/">most susceptible</a> to the binding of copper ions. This is because in damaged hair the disulfide groups have “broken bonds” (the link that holds the elements within these groups together is broken), making it easier for the copper ions to bind to the hair.</p> <h2>Can I prevent the green colour or get rid of it?</h2> <p>To prevent your hair from turning green in a swimming pool, you have two basic options. The first is a physical barrier – just wear a swim cap.</p> <p>The second option is chemical – you can pre-treat your hair with an alkaline shampoo. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0891584918310050">Studies have shown</a> under alkaline pH conditions, the copper ions won’t attach to the hair. To treat your hair before going to the pool, you can either use a shampoo with a pH higher than 7, or you can even try mixing some baking soda into your regular shampoo.</p> <p>But what can you do if your hair has already turned greenish? Well, you can try washing your hair with a shampoo designed to achieve this, typically marketed as a “chlorine removal” shampoo. These products contain a chemical called EDTA – it can bind to metal ions (such as copper) and thus will remove copper from the hair.</p> <p>You may have heard tomato sauce or ketchup is a good way to get the green out of your pool hair – potentially because the red pigments are supposed to “cancel out” the green ones. However, I’m not aware of any scientific evidence this would work.</p> <p><em>Correction: This article has been amended to clarify that alkaline shampoos have a pH higher than 7, not lower.</em><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/211736/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/magdalena-wajrak-1432339"><em>Magdalena Wajrak</em></a><em>, Senior lecturer, Chemistry, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p><em>Image </em><em>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.

My Royal Melbourne Seniors Classic Adventure: A day on the greens (and in the bunkers!)

<p dir="ltr">G'day to all past, present, and emerging golf enthusiasts!</p> <p dir="ltr">If you're a senior golfer like me, hunting for inspiration, adventure, and authentic golf yarns — this is for you.</p> <p dir="ltr">Picture this: a crisp August morning, and sixty-two senior golfers gathered on Royal Melbourne's West Course for the Vic Seniors Classic 2023. Here's the story of how it all went down...</p> <p dir="ltr">Before anything else, I mustered the guts to jump in. Ever heard of "imposter syndrome"? Trust me, I was its best mate. But the requirements were clear: age 55+ (I'm a proud 65-year-old), GA Handicap under 24.5 (18.5), and a $225 entry fee. Wait, $225? Given that Royal Melbourne's green fees dance around $1000, caddy fee included, it was a no-brainer.</p> <p dir="ltr">Fueled by the temptation of playing a top-notch course for a quarter of the fee, I submitted my application without hesitation. Before I knew it, my name adorned the list of players.</p> <p dir="ltr">As the day approached, I was geared up to tackle the Royal Melbourne challenge.</p> <p dir="ltr">The 8 am shotgun start meant groups teed off from various holes. I found myself at the 11th tee, flanked by two fierce competitors: Peter (Daily Handicap 1) and Damian (12). Yours truly? A modest 20.</p> <p dir="ltr">Standing over the ball, knees a tad wobbly, I swung that driver. The ball sailed gracefully, landing centre fairway, while their shots had taken a wilder route into the rough. The lesson? 'How near,' not 'how far'.</p> <p dir="ltr">Now, let's talk about those Royal Melbourne greens. Rumour had it, they were "super fast". Super fast? Imagine sliding a ball across your kitchen's polished tiles — yep, that rapid.</p> <p dir="ltr">Around the course, bunkers became my stern mentors — big, deep, and oh-so unforgiving.</p> <p dir="ltr">Post 18 holes, scorecards were in, followed by the triumphant crowning of winners over lunch.</p> <p dir="ltr">Rodney Ware (75 gross) and Kevin Naismith (81 gross) led in men's gross, while Wayne Moon (72 net) and Craig Lonsdale (73 net) dominated the net division. Melinda Crawford (16, scratch stableford) and Louise Yuen (29 handicap points) shone in the women's.</p> <p dir="ltr">Kudos to winners, fellow players, Royal Melbourne and Golf Australia for the unforgettable day.</p> <p dir="ltr">By the way, can you see yourself on those hallowed Royal Melbourne greens? If your inner golfer nods, I'm your cheerleader. Consider joining me for the 2024 Royal Melbourne Seniors Classic.</p> <p dir="ltr">And as I wrap up, let me leave you with the timeless words of the legendary Peter Thomson: "Golf is a game of how near, not how far".</p> <p dir="ltr">Until next time, keep those swings buttery, putts steadfast, and steer clear of those tricky bunkers.</p> <p dir="ltr">PS: My result? T43rd (net) among the 48 male players. Next time I'll be swinging even better.</p> <p dir="ltr"><strong><em>About the Writer: Mike Searles is a Melbourne retiree who's living the golfing dream.</em></strong></p> <p><em>Image credits: Getty Images</em></p>

Mystery object washed up on WA beach finally identified

<p>Ok space enthusiasts and beachcombers. Here's one for the X-Files – Intergalactic Travel edition.</p> <p>Picture this: A strange and baffling object, looking like it's straight out of a sci-fi flick, decided to take a little trip to Green Head beach, about 250 kilometres north of Perth on the pristine WA coastline.</p> <p>As soon as the locals caught sight of this extraterrestrial-looking thingamajig, the news spread like wildfire, and it made international headlines faster than a speeding rocket, with all kinds of fascinating theories popping up as to what on <em>Earth</em> (or not on Earth) it could be.</p> <p>Was it a UFO? A top-secret government experiment gone awry? Well, turns out it was nothing that exciting. The Australian Space Agency put on their Sherlock Holmes hats and deduced that this enigmatic piece of debris probably came from a satellite launch vehicle. Eureka! Case closed!</p> <p>Of course, when something weird and otherworldly shows up on your doorstep, you can't be too careful. So, the local authorities played it safe and put the object under police guard for an entire week. (Better safe than sorry, right?)</p> <p>And who needs a red carpet when you have a front-end loader to transport your newfound cosmic artifact? The experts were summoned to figure out where this space junk came from, and they concluded it was most likely a fuel tank from some rocket launched by the Indian Space Research Organisation. </p> <p>Professor Alice Gorman from Flinders University explained to <a href="https://www.abc.net.au/news/2023-07-31/australian-space-agency-identifies-space-junk-green-head/102669472" target="_blank" rel="noopener">ABC News</a> that this fuel containment vessel was meant to fall off after launch. And it turns out that statistically, we've been pretty lucky not to have had more collisions with falling rocket parts. Imagine explaining that to your insurance company? "A rocket booster landed on my house. Is that covered?"</p> <p>But here comes the tricky part: What to do with all of this space garbage? Should they ship it back to India like some interstellar postcard, or leave it Down Under as an intergalactic souvenir?</p> <p>While India is technically (and legally) responsible for their space debris, they could decide to gift it to Australia if they so choose. It could be like an exotic space decoration for the country - "The Land of Kangaroos and Rocket Wreckage."</p> <p>Even better, the Green Head community itself appear to have come up with a few fabulous ideas. Forget the Sydney Opera House: let's make the space debris a tourist attraction! Move over, Eiffel Tower - we've got our own piece of space history right here.</p> <p>The WA Premier even suggested storing it next to space debris from NASA's Skylab space station (remember that?) in some kind of attempt to build a cosmic cabinet of curiosities. </p> <p>Of course, the local council is also very keen on keeping this celestial treasure. They're hoping the Indian government won't come back to claim it, to the point that everyone in the surrounding Shire of Coorow is buzzing with excitement over the possibility of having their very own space souvenir to draw crowds of star trekkers.</p> <p>And so while the mystery of the object on the beach has been solved, the debate over its fate is just beginning. Will it become a star attraction in a local park? Or will it be shipped off to India like an interplanetary package return? Only time will tell.</p> <p><em>Images: Nine News</em></p>

Mysterious liquid turns popular rock pool green

<p>A mysterious liquid has turned a popular public rock pool at Cronulla beach fluorescent green.</p> <p>The liquid, believed to be a natural fluorescent dye, fluorescein, was seen pouring into the usually clear waters of the pool on Friday.</p> <p>The dye is often used to help experts track the flow of water to identify any leaks and has low toxicity, which means it is harmless despite the daunting colour.</p> <p>“We believe the discolouration is likely to be fluorescein dye, which is commonly used in plumbing/drain testing and dissipates quickly once diluted,” a spokesperson for the New South Wales Environmental Protection Authority said.</p> <p>According to Australian dye manufacturer, Tintex, the dye is also used to “locate leaks in plumbing, tracing pipe locations, detect drain damage and water pathways,” and is odourless and non-toxic to the environment.</p> <p>However, in a safety data sheet, Tintex has also warned about the potential health effects which include eye irritation, skin irritation, irritation of the digestive tract and respiratory tract irritation.</p> <p>Many locals are cautious despite the claim that the dye is mostly harmless.</p> <p>One user wrote on a Facebook page for Cronulla locals that dye was “legal to use in a stormwater drain”.</p> <p>“Doesn’t look good whatever it is,” another responded, while other cautious residents replied that they wouldn’t swim in the area until the dye fully dissipates.</p> <p><em>Images: Facebook</em></p>

6 best screening hedge plant

<h4>Lillipilly</h4> <p>With its dense screen and fast growing habit, lillipilly can grow up to eight metres tall but should be pruned to thicken the foliage. The Syzygium smithii variety is commonly known as ‘Neighbours Be Gone’.</p> <h4>Juniper</h4> <p>A conifer such as Juniperas spartan is an excellent choice due to its dense evergreen dark blue-green coloured foliage. This column-shaped hardy plant grows to three metres in 10 years and no trimming or pruning is required.</p> <h4>Camellia</h4> <p>Camellias come in two main varieties, japonica and sasanqua. For hedging, the sasanqua is the preferred choice with its faster growing habit, smaller leaves and better sun tolerance. The flowers in autumn are an added bonus.</p> <h4>Photinia</h4> <p>Photinias come in larger and smaller leaf varieties with the smaller leaf types more suitable for hedges up to two metres. With an overall deep green leaf appearance, the new growth comes as striking red foliage.</p> <h4>Murraya</h4> <p>A great alternative to box hedges with a somewhat similar texture but lighter green leaves, murraya is fast growing and easy to care for, with a pretty flush of orange blossom scented flowers in spring and summer.</p> <h4>English Box</h4> <p>Box is the most popular choice for hedging and is the best choice for a more formal look. Its slow growing tendency means it will not provide privacy for several years, but the bonus is it’s easy to maintain.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/gardening-tips/best-screening-hedge-plants" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

How to make your next holiday better for the environment

<p><a href="https://theconversation.com/profiles/brendan-canavan-228682">Brendan Canavan</a>, <em><a href="https://theconversation.com/institutions/university-of-nottingham-1192">University of Nottingham</a></em></p> <p>Being an environmentally friendly tourist can be challenging. Tourism is an industry that brings many <a href="https://www.unwto.org/EU-guidebook-on-sustainable-tourism-for-development">negative environmental impacts</a> – our pleasure often comes at the expense of local habitats or wildlife.</p> <p>Maya Bay on Thailand’s uninhabited Phi Phi Leh island became famous as the location of the 2000 Hollywood movie The Beach. But this led to rapid growth in visitors to the bay – as many as 8,000 a day at its peak – and put enormous strain on the bay’s natural habitats.</p> <p>In 2018, the bay was <a href="https://edition.cnn.com/travel/article/maya-bay-thailand-recovery-c2e-spc-intl/index.html">closed to tourists</a> for four years to let its coral reefs and wildlife recover.</p> <p>But tourism can also be an inspiring way to connect with oneself, with others and with new places. As tourists, we can learn, share and contribute to positive environmental practices.</p> <p>As a tourist, you also have influence. The money you spend, the social interactions you have and the resources you consume all <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517715300224?casa_token=TaXMOLW6Sp4AAAAA:PEnSG1AaAZ-MiuTNZ1wJfLRrzaNVIbaBsk1cKsP8M-_6KjruLO9tp09BqqzGnJTIZbN8_CoP4Q">help to shape an area</a>.</p> <p>So here are four pieces of advice for making your next holiday better for the environment.</p> <h2>Spend locally</h2> <p>We’ve all heard variations on the mantra “<a href="https://cleanisland.org/history-of-the-leave-only-footprints-initiative/#:%7E:text=%E2%80%9CTake%20only%20memories%2C%20leave%20only,the%20Leave%20Only%20Footprints%20program.">take only memories, leave only footprints</a>”. This message of less consumption and lower impact is a good ethos for environmentally sensitive tourism. The first thing to do is think about how you can leave more positive footprints behind.</p> <p>An excellent way to make the most of your economic footprint is to stay and shop in <a href="https://www.tandfonline.com/doi/full/10.1080/09669580802359293?casa_token=eNeLWWRPHxIAAAAA:9bT4S5-0O5b2JQWrYKgmjtDxrZzlv0P-H-9T2SoWT1fX6tFRkoVenNNcfmJbHV9ebhF2kP7XIEgz">independent businesses</a>. These businesses tend to pay local taxes and are owned by and employ local people.

In 2010, the country’s Khama Rhino Sanctuary employed 26 permanent staff and many more casual labourers.</p> <p>This economic security can, in turn, prompt local people to appreciate the importance of protecting vulnerable animal species like rhinos. <a href="https://www.tandfonline.com/doi/abs/10.1080/09669582.2021.1932927?casa_token=rffO3wgsu6UAAAAA:7dounwsgVunXCW4-NERDNDX9Ks_OVfa3z5TfZDojAdiVVKuXbU52_3DnRNfALNjMCW0PzGPPOu0MQQ">Separate research</a> on people living around Kenya’s Maasai Mara nature reserve found that people whose livelihoods were dependent on tourism were more likely to support efforts to conserve local wildlife.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/524360/original/file-20230504-19-znuosc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Two white rhinos drinking from a pond." /><figcaption><span class="caption">Two white rhinos at Khama Rhino Sanctuary, Botswana.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/white-rhinoceros-ceratotherium-simum-squarelipped-khama-2060738441">Al Carrera/Shutterstock</a></span></figcaption></figure> <h2>Tread lightly</h2> <p>Tourism creates waste and uses up resources. Treading carefully will minimise the environmental impact you have on your holiday destination.</p> <p>A simple way to lower your environmental footprint is to use fewer resources at every stage of your holiday. A single tourist uses <a href="https://www.e-unwto.org/doi/pdf/10.18111/9789284414529">300 litres</a> of water in their holiday accommodation on average each night. Reusing towels, flushing the toilet less and shortening your shower time can all help to reduce demand for water resources.</p> <p>Thinking about the footprints you leave as a tourist is a useful mindset. You may even become more aware of the positive legacy you can leave behind.</p> <p>Learn about the local area and the environmental issues that matter there. If habitat loss is a problem, contribute to local organisations that support conservation. Organisations like the <a href="https://www.nationaltrust.org.uk/holidays">National Trust</a> even offer holidays in the UK that help to fund their work.</p> <h2>Place matters</h2> <p>Tourism shifts you away from the familiar and gives you <a href="https://www.sciencedirect.com/science/article/abs/pii/S0160738312001211?casa_token=zHTCleS_F3kAAAAA:jWMOOtEJzH8OXySUqafP5Z7koLFOtNSJ2Ik4ncoA9wPCHTW-1MRNJJwRvYtoopoSqCwTRm_TeA">space for self-reflection</a>.

And many alternative types of tourism are too. These tourists can become powerful advocates for the protection of the places they care deeply about. Surf tourists, for example, have driven <a href="https://www.sas.org.uk/">various campaigns</a> against the discharge of sewage into UK bathing waters.</p> <p>You and those you travel with can be similar cheerleaders for the places you care about.

Can death on the screen feel the same as a ‘real’ one?

<p>Death is a part of life, an adage usually reserved for those who physically exist in our lives – family, friends, colleagues, acquaintances. So what happens when a profound death experience happens on the screen? Is that still a legitimate experience of mourning?</p> <p>Last week, the popular TV show <em>Succession</em> had a significant “on screen” death - where even the cast filming the scene spoke as if the response to the trauma had a very <a href="https://www.independent.co.uk/arts-entertainment/tv/news/succession-episode-three-logan-dead-b2317366.html">real feeling</a>. </p> <p>In the same way as the cast, social media reactions to the sudden and unexpected death of a person with a complex character, after four seasons of growing to understand them, can feel like the death of someone you actually know. </p> <p>The <a href="https://royalsocietypublishing.org/doi/full/10.1098/rstb.2017.0267#d3e765">research</a> behind this phenomenon can be found as far back as the 1970s when early understandings around the death of a main character on children’s television served to provide real world insight into the irreversibility of death as a universal experience.</p> <p>Over time, as popular culture and television became more nuanced, the diversity of the ways in which death occurred in fictional programs began to <a href="https://www.sagepub.com/sites/default/files/upm-binaries/5234_Bryant__Death,_Dying,_Dead,_Popular_Culture.pdf">replicate the complexity</a> of “real” loss in our lives. Via television, we get access to catastrophic loss, multiple casualty events, loss after significant illness – as well as seeing how death impacts the people left behind.</p> <p>In the most recent episode of <em>Succession</em>, we also see what happens when a death occurs involving a person where their character or relationship to others is strained. We see ways in which grief is not always a byproduct of love.</p> <h2>Why does this grief feel real from an armchair perspective?</h2> <p>Death on screen can also act as a trigger or a reminder of the losses we have endured.</p> <p>When a show realistically portrays grief in its purest form, the emotive or reflective reaction can unlock our own grief. Engaging with the small screen is an overt act of escapism, often for entertainment. We might be switching on a program with the intention of relaxation, only to be met with trauma and sadness.</p> <p>When a sudden loss is brought into our lounge rooms, or via the devices on our laps, we experience shock, confusion and anger about the abruptness of an event, just like the feelings we can experience when loss happens suddenly in our real lives.</p> <p>Safe reporting of sudden and traumatic death on fictional TV shows is not covered by media reporting guidelines. Warnings prior to a scene, or consistent information at the end of an episode about seeking additional support, might be minimal. </p> <p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0266722">Recent research</a> identifies multiple contexts related to warnings where TV shows may note that an episode will explore death, however, the complexity of how this might be portrayed is limited.</p> <figure> <h2>What is this grief called?</h2> <p>While there is no rulebook for grief, reacting emotionally to a small screen death can bring about concerns that we look silly or that we lack awareness of the distinction between reality and fiction. This form of <a href="https://journals.sagepub.com/doi/full/10.1177/00302228211014775?casa_token=qZ3_RQR6xw0AAAAA%3Awv53_SeeKUgDIH34Z3diViJjcghG-dJb39n--oZP5-Gz-vCRn8RTQOmNxVFZ34fnNjdrwNDriq8GCg">parasocial grieving</a>, described as having feelings attached to a pseudo-relationship, does feel real, does have consequences and does need space to be managed. </p> <p>We don’t all watch the same shows, we don’t all respond to the death of a character the same way, we might even struggle to understand why people have the reactions they do when a TV death occurs. I would encourage you to pause for a moment and remember the ones that did get under our skin. </p> <p>In 1985, Australian viewers lived through the death of <a href="https://www.theguardian.com/tv-and-radio/2020/feb/06/how-mollys-death-on-a-country-practice-touched-a-nation-the-writers-room-was-shedding-tears">Molly from <em>A Country Practice</em></a>, where the final image of a mother’s end-stage cancer diagnosis played out while watching her daughter fly a kite. </p> <p>Teens watching Sarah Michelle Gellar stumble across the sudden untimely death of her mother in <em><a href="https://www.theatlantic.com/entertainment/archive/2017/03/the-body-the-radical-empathy-of-buffys-best-episode/519051/">Buffy the Vampire Slayer </a></em>shaped many feelings when there is a catastrophic loss without warning. </p> <p>In the last decade, the <a href="https://www.theguardian.com/culture/australia-culture-blog/2013/aug/08/offspring-fans-mourn-patrick">sudden death of Patrick from <em>Offspring </em></a>had people legitimately calling in sick from work the next day. </p> <p>The <a href="https://www.youtube.com/watch?v=kAgpbPIVy0M">global reaction</a> to the Red Wedding scene in <em>Game of Thrones</em> had forums on Reddit unpacking why so many characters were murdered and sharing the impact of the sights and sounds of blood and murder and traumatic grief.</p> <p>We engage in a social contract when we connect to a TV show. We expect to be removed from our real life and engage in the viewing of other spaces. Death in those spaces – and the reactions to that loss – can feel as if they break that contract.</p> <p><em>Image credits: HBO</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/can-death-on-the-screen-feel-the-same-as-a-real-one-203549" target="_blank" rel="noopener">The Conversation</a>. </em></p> </figure>

Age, not weight, should be the big decider in whether to screen for diabetes

<p><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Because it’s possible to be diabetic or prediabetic without any symptoms, and early diagnoses lead to better health outcomes, lots of countries have screening programs for diabetes.</span></p> <div class="copy"> <p>In the US, overweight or obese people between 35 and 70 are recommended to regularly get diabetes tests.</p> <p>But <a href="https://www.ajpmonline.org/article/S0749-3797(23)00006-5/fulltext" target="_blank" rel="noreferrer noopener">new research</a> in the <em>American Journal of Preventative Medicine</em> has called this into question, suggesting that screening based purely on age will catch the greatest proportion of diabetic and prediabetic people.</p> <p>“It might sound counterintuitive because we think of being overweight or obese as the primary cause of diabetes,” says lead author Dr Matthew O’Brien, an associate professor of medicine at Northwestern University Feinberg School of Medicine, US.</p> <p>“But if we make decisions about diabetes testing based on weight, we will miss some people from racial and ethnic minority groups who are developing prediabetes and diabetes at lower weights.”</p> <p>The researchers examined data from all the 2021 diabetes screenings recommended by the US Preventive Services Task Force. Based on this data, they recommend screening every US adult aged between 35 and 70.</p> <p>“All major racial and ethnic minority groups develop diabetes at lower weights than white adults, and it’s most pronounced for Asian Americans,” says O’Brien.</p> <p>Roughly half of US adults have Type 2 diabetes or prediabetes, and 81% of adults with prediabetes don’t know they have it. Diagnoses are delayed in ethnic minorities, compared to white people.</p> <p>“Diabetes is a condition in which unacceptable racial and ethnic disparities persist,” says O’Brien.</p> <p>“That’s why we need a screening approach that maximises equity. If we can find everyone earlier, it helps us reduce these disparities and the bad outcomes that follow.”</p> <p>The researchers also found that it might be beneficial for members of some ethnic minorities to receive earlier screening, but they don’t formally recommend it.</p> <p>“It’s imperative that we identify a screening approach that is equitable across the entire US population,” says O’Brien.</p> <p>“Our findings illustrate that screening all adults aged 35 to 70 years, regardless of weight or body mass index, performs equitably across all racial and ethnic groups.”</p> <p>This age cut-off also makes it much simpler for clinicians to decide whether someone should get a diabetes test.</p> <p>“There are many ways to nudge patients and providers to complete this testing, which should be the focus of future research,” says O’Brien.</p> <p>In Australia, diabetes tests are recommended based on a <a href="https://www.healthdirect.gov.au/diabetes-screening-tests" target="_blank" rel="noreferrer noopener">range of risk factors</a>, including age, waist measurement, ethnicity, physical activity and family history. Diabetes Australia has a <a href="https://www.diabetesaustralia.com.au/risk-calculator/" target="_blank" rel="noreferrer noopener">risk calculator</a> with which you can determine your own risk.</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=240911&title=Age%2C+not+weight%2C+should+be+the+big+decider+in+whether+to+screen+for+diabetes" width="1" height="1" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /></div> <div id="contributors"> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/health/diabetes-tests-screening-age-weight/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by <a href="https://cosmosmagazine.com/contributor/ellen-phiddian">Ellen Phiddian</a>. </em></p> <p><em>Images: Shutterstock</em></p> </div>

Hilarious footage emerges of Sam Neill's James Bond screen test

<p dir="ltr"><em>Jurassic Park</em> star Sam Neill appeared on the <em>Today</em> show to discuss his career and new memoir 'Did I Ever Tell You This?' but the hosts had other plans.</p> <p dir="ltr">Karl Stefanovic, Sarah Abo and Brooke Boney managed to dig up an old screen test that left the 75-year-old red-faced.</p> <p dir="ltr">"Oh, my God, no - That is so cruel to play that, so cruel," a flustered Neil said, as footage from his <em>James Bond</em> audition started rolling.</p> <p dir="ltr">In the video, a young Neill armed with a gun and donning an unbuttoned shirt bursts into a bedroom-to the surprise of a naked woman- and says the famous line "My friends called me Bond, James Bond".</p> <p dir="ltr">Neill said he was thankful that he didn’t get the part and that someone else was chosen to do the role.</p> <p dir="ltr">"I felt so awkward all day that we made that thing and it just went on and on and on," he said.</p> <p dir="ltr">"I am so relieved they offered it to someone else, they are welcome to it - you don't want to be the Bond that no-one likes, you know - that is a fate worse than death."</p> <p dir="ltr">Although he didn’t get the role of agent 007, the actor has starred in three of the J<em>urassic Park films, Event Horizon, The Dish and Peter Rabbit</em>.</p> <p dir="ltr">He also told the <em>Today </em>show hosts that he never intended on becoming a professional actor and his success was completely unexpected.</p> <p dir="ltr">"I never really imagined I would have a career in film, let alone a career as an actor," he said.</p> <p dir="ltr">"At the rather advanced age of 30 I suddenly realised I could make a living at what I loved best and I never looked back until I wrote (the memoir) and it has been good to look back - it has been really good for me."</p> <p><em>Image: Today Show, Channel 9</em></p>

Urine sample test: new way to detect and screen for early stages of Alzheimer’s disease

<p>When it comes to <a href="https://cosmosmagazine.com/science/alzheimers-peer-review/" target="_blank" rel="noreferrer noopener">Alzheimer’s disease</a>, an early diagnosis – one made well before signs of irreversible dementia are apparent – is key to providing effective intervention and treatment. Now early detection might be as simple as a urine test, allowing for wide-scale and early screening across large populations of the elderly.</p> <p>A collaboration of researchers in China investigated urine samples for biomarkers from a large group of patients with varying severity of Alzheimer’s disease, comparing them with healthy controls.</p> <p>A compound known as <a href="https://www.acs.org/content/acs/en/molecule-of-the-week/archive/f/formic-acid.html?cid=home_motw" target="_blank" rel="noreferrer noopener">formic acid</a> (which is also produced by some ant and bee species) was a particularly sensitive marker for cognitive decline associated with Alzheimer’s disease. Significant increases in urinary formic acid levels were found in all samples from Alzheimer’s sufferers (including those with only early-stage subjective cognitive decline) as compared with those from the healthy controls.</p> <p>“Alzheimer’s disease is a continuous and concealed chronic disease, meaning that it can develop and last for many years before obvious cognitive impairment emerges,” say the authors. “The early stages of the disease occur before the irreversible dementia stage, and this is the golden window for intervention and treatment.”</p> <p>When blood samples of the participants were analysed for Alzheimer’s biomarkers in combination with the urinary formic acid level, the researchers were able to predict to what stage of the disease the patient had progressed. Their report is in <em><a href="https://www.frontiersin.org/articles/10.3389/fnagi.2022.1046066/full" target="_blank" rel="noreferrer noopener">Frontiers in Ageing</a></em>.</p> <p>Other methods currently used to diagnose Alzheimer’s disease, such as positron emission tomography brain scans, <a href="https://cosmosmagazine.com/health/medicine/alzheimers-blood-test-developed/" target="_blank" rel="noreferrer noopener">invasive blood draws</a> and lumbar punctures, tend to be costly and invasive. Although other urinary biomarkers for Alzheimer’s disease have been found, none have been able to detect the disease at its earliest stages.</p> <p>The links between urinary formic acid and Alzheimer’s disease are still not fully understood, but this research is an important step towards developing tools to diagnose and treat this debilitating condition amongst a vulnerable group in society.</p> <p>“Urinary formic acid showed an excellent sensitivity for early Alzheimer’s screening,” said the authors. “The detection of urine biomarkers of Alzheimer’s is convenient and cost-effective, and it should be performed during routine physical examinations of the elderly.”</p> <p></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=227116&title=Urine+sample+test%3A+new+way+to+detect+and+screen+for+early+stages+of+Alzheimer%E2%80%99s+disease" width="1" height="1" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /></p> <p></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/health/urine-new-way-detect-alzheimers-disease/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Clare Kenyon. </em></p> <p><em>Image: Getty Images</em></p> </div>

How Jamie Durie is revolutionising greener building

<p>Jamie Durie is using his knowledge and expertise to help educate people on the importance of greener building. </p> <p>The celebrity gardener has partnered with Victorian boutique builder <a title="Chatham Homes" href="https://chathamhomes.com.au/" target="_blank" rel="noopener">Chatham Homes</a>, to help the home construction industry in confronting the challenges of living through the ongoing climate crisis. </p> <p>Jamie told <a href="https://www.nine.com.au/property/homes/how-jamie-durie-is-encouraging-greener-building/a751b122-af38-48e7-a729-b961eafb5a78" target="_blank" rel="noopener">Nine</a> that he doesn't know "of any other builder in Australia that has gone to these sorts of lengths to ensure Australian families and the environment end up with a healthier future."</p> <p>Through his work, Jamie said he is particularly keen on shedding light on the damaging nature of VOCs (Volatile Organic Compounds) that can be found in the home.</p> <p>With Jamie's assistance, Chatham Homes has made it their priority to ensure their homes are not only using low VOC paint, but also zero VOC glue in their joinery systems.</p> <p>VOCs are described as a large group of chemicals that are found in the products used to construct and maintain our homes, and can be found in paints, upholstery, glue and laminates.</p> <p>According to the <a title="Australian Government's Department of Climate Change, Energy, the Environment and Water" href="https://www.dcceew.gov.au/environment/protection/npi/substances/fact-sheets/total-volatile-organic-compounds" target="_blank" rel="noopener">Australian Government's Department of Climate Change, Energy, the Environment and Water</a>, dangerous side effects of inhaling VOCS can include irritation to the eyes, nose and throat, loss of coordination, nausea, and damage to the liver, kidney and central nervous system.</p> <p>"There are a lot of builders out there who don't know what VOCs are," Jamie tells Nine. "And you look at Chatham and they're not only using low VOC paints, they're using zero VOC glue in their joinery systems. It's really quite amazing."</p> <p>"They proof-test the entire home, they vacuum-test. So it's an 8.2 energy star rating which is the highest level of any home builder in Australia."</p> <p>Jamie reveals that the impacts of VOCs are only starting to become common knowledge.</p> <p>"The average new home has around 20 times the acceptable level of VOCs that a human being should experience. A lot of it is just coming to the surface," he says.</p> <p>"It's about building healthy buildings and providing wellbeing to Australian families. A lot of people don't realise these VOCs are carcinogenic."</p> <p>"[Chatham Homes] have taken it upon themselves to investigate and incorporate these as standard building practices in all their homes," says Jamie.</p> <p><em>Image credits: Instagram</em></p>
