Better sleep is a protective factor against dementia

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, <a href="https://theconversation.com/institutions/monash-university-1065"><em>Monash University</em></a></em></p> <p>Dementia is a progressive loss of cognitive abilities, such as memory, that is significant enough to have an impact on a person’s daily activities.</p> <p>It can be caused by a number of different diseases, including <a href="https://alzheimer.ca/en/about-dementia/what-alzheimers-disease">Alzheimer’s</a>, which is the most common form. Dementia is caused by a loss of neurons over a long period of time. Since, by the time symptoms appear, many changes in the brain have already occurred, many scientists are focusing on studying the risk and protective factors for dementia.</p> <p>A risk factor, or conversely, a protective factor, is a condition or behaviour that increases or reduces the risk of developing a disease, but does not guarantee either outcome. Some risk factors for Alzheimer’s disease and dementia, such as age or genetics, are not modifiable, but there are several other factors we can influence, <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">specifically lifestyle habits and their impact on our overall health</a>.</p> <p>These risk factors include depression, lack of physical activity, social isolation, high blood pressure, obesity, diabetes, excessive alcohol consumption and smoking, as well as poor sleep.</p> <p>We have been focusing our research on the question of sleep for over 10 years, particularly in the context of the <a href="https://www.nhlbi.nih.gov/science/framingham-heart-study-fhs">Framingham Heart Study</a>. In this large community-based cohort study, ongoing since the 1940s, the health of surviving participants has been monitored to the present day. As researchers in sleep medicine and epidemiology, we have expertise in researching the role of sleep and sleep disorders in cognitive and psychiatric brain aging.</p> <p>As part of our research, we monitored and analyzed the sleep of people aged 60 and over to see who did — or did not — develop dementia.</p> <h2>Sleep as a risk or protective factor against dementia</h2> <p>Sleep appears to play an essential role in a number of brain functions, such as memory. Good quality sleep <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2793873">could therefore play a vital role in preventing dementia</a>.</p> <p>Sleep is important for maintaining <a href="https://www.science.org/doi/10.1126/science.1241224">good connections in the brain</a>. Recently, research has revealed that sleep seems to have a function similar to that of a garbage truck for the brain: <a href="https://doi.org/10.1016/j.mad.2023.111899">deep sleep could be crucial for eliminating metabolic waste from the brain</a>, including clearing certain proteins, such as those known to accumulate in the brains of people with Alzheimer’s disease.</p> <p>However, the links between deep sleep and dementia still have to be clarified.</p> <h2>What is deep sleep?</h2> <p>During a night’s sleep, we go through several <a href="http://ceams-carsm.ca/en/a-propos-du-sommeil/">sleep stages</a> that succeed one another and are repeated.</p> <p>NREM sleep (non-rapid eye movement sleep) is divided into light NREM sleep (NREM1 stage), NREM sleep (NREM2 stage) and deep NREM sleep, also called slow-wave sleep (NREM3 stage). The latter is associated with several restorative functions. Next, REM sleep (rapid eye movement sleep) is the stage generally associated with the most vivid dreams. An adult generally spends around 15 to 20 per cent of each night in deep sleep, if we add up all the periods of NREM3 sleep.</p> <p>Several sleep changes are common in adults, such as going to bed and waking up earlier, sleeping for shorter periods of time and less deeply, and waking up more frequently during the night.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=279&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=279&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=279&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=350&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=350&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=350&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Sleep stages, and the role of deep sleep for brain health.</span> <span class="attribution"><span class="source">(Andrée-Ann Baril)</span></span></figcaption></figure> <h2>Loss of deep sleep linked to dementia</h2> <p>Participants in the <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2810957">Framingham Heart Study</a> were assessed using a sleep recording — known as polysomnography — on two occasions, approximately five years apart, in 1995-1998 and again in 2001-2003.</p> <p>Many people showed a reduction in their deep slow-wave sleep over the years, as is to be expected with aging. Conversely, the amount of deep sleep in some people remained stable or even increased.</p> <p>Our team of researchers from the Framingham Heart Study followed 346 participants aged 60 and over for a further 17 years to observe who developed dementia and who did not.</p> <p>Progressive loss of deep sleep over time was associated with an increased risk of dementia, whatever the cause, and particularly Alzheimer’s type dementia. These results were independent of many other risk factors for dementia.</p> <p>Although our results do not prove that loss of deep sleep causes dementia, they do suggest that it could be a risk factor in the elderly. Other aspects of sleep may also be important, such as its duration and quality.</p> <h2>Strategies to improve deep sleep</h2> <p>Knowing the impact of a lack of deep sleep on cognitive health, what strategies can be used to improve it?</p> <p>First and foremost, if you’re experiencing sleep problems, it’s worth talking to your doctor. Many sleep disorders are underdiagnosed and treatable, particularly through behavioural (i.e. non-medicinal) approaches.</p> <p>Adopting good sleep habits can help, such as going to bed and getting up at consistent times or avoiding bright or blue light in bed, like that of screens.</p> <p>You can also avoid caffeine, limit your alcohol intake, maintain a healthy weight, be physically active during the day, and sleep in a comfortable, dark and quiet environment.</p> <p>The role of deep sleep in preventing dementia remains to be explored and studied. Encouraging sleep with good lifestyle habits could have the potential to help us age in a healthier way.<!-- Below is The Conversation's page counter tag.

Whooping cough is surging in Australia. Why, and how can we protect ourselves?

<p><em><a href="https://theconversation.com/profiles/laurence-don-wai-luu-1415508">Laurence Don Wai Luu</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p>Australia is facing a whooping cough outbreak. Some <a href="https://nindss.health.gov.au/pbi-dashboard/">2,799 cases</a> were recorded in the first three months of 2024. Cases are highest in Queensland and New South Wales, with more than 1,000 recorded in each state.</p> <p>The last time Queensland recorded more than 1,000 cases in three months was <a href="https://nindss.health.gov.au/pbi-dashboard/">the first quarter of 2013</a>. This was at the tail end of a significant outbreak that spanned 2008 until 2012 – Australia’s largest reported outbreak since the <a href="https://www1.health.gov.au/internet/main/publishing.nsf/Content/cda-cdi2205-pdf-cnt.htm/$FILE/cdi2205c.pdf">widespread introduction</a> of whooping cough vaccines <a href="https://www1.health.gov.au/internet/main/publishing.nsf/Content/cda-pubs-annlrpt-oz_dis19_91.htm/$FILE/ozdis1917_91.pdf">in the 1950s</a>. More than 140,000 cases were recorded during this period, with the number peaking at 38,748 in 2011.</p> <p>There was a smaller outbreak between <a href="https://nindss.health.gov.au/pbi-dashboard/">2014 and 2017</a>, with more than 60,000 cases in these years.</p> <p>So what is whooping cough, why are cases rising now, and how can you protect yourself?</p> <h2>It’s most dangerous for babies</h2> <p>Whooping cough is a serious and <a href="https://www.healthdirect.gov.au/whooping-cough">highly contagious</a> respiratory disease. Also called pertussis, it’s caused by the bacteria <em>Bordetella pertussis</em>.</p> <p>The initial symptoms of whooping cough resemble other cold and flu-like symptoms. These include runny nose, sneezing, mild cough and fever. However, as the disease progresses into the second week, the coughing fits become worse and more frequent. After or between bouts of coughing, patients may gasp for air and produce the characteristic “whoop” noise.</p> <p>The disease is also sometimes called the “100-day cough” as it can last for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7150027/">6–12 weeks</a>. It’s especially serious and can be life-threatening in newborns who are yet to receive their vaccinations. In older children who are fully vaccinated, as well as adolescents and adults, the disease is normally less severe. However, even in adults, the coughing can lead to <a href="https://www.nejm.org/doi/full/10.1056/NEJMicm1701940">fractured ribs</a>.</p> <p>Antibiotics are used to <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/ebch.1845">treat whooping cough</a> but are most effective when given during the initial stages of the illness. The best protection in the first instance is <a href="https://www.healthdirect.gov.au/whooping-cough">vaccination</a>, which prevents most cases of serious illness, and reduces the spread of whooping cough in the community.</p> <p>It’s recommended children are given six doses of a whooping cough vaccine (which is combined with vaccines for other diseases) between the ages of roughly two months and 13 years. Vaccination is free under the <a href="https://www.health.gov.au/topics/immunisation/vaccines/whooping-cough-pertussis-immunisation-service">National Immunisation Program</a> for children and pregnant women. Vaccinating women against whooping cough during pregnancy protects newborns in their first months of life.</p> <p>Immunity from these vaccines wanes over time, so it’s also recommended adults receive a booster, particularly those who may come into frequent contact with babies.</p> <h2>Why are cases rising now?</h2> <p>Whooping cough outbreaks generally occur <a href="https://www.healthdirect.gov.au/whooping-cough">every 3–4 years</a>. Due to COVID measures such as border closures, social isolation and masks, the number of cases declined dramatically during 2020–23. If trends had followed the usual outbreak cycle, this might have been around the time we’d have seen another outbreak.</p> <p>Missed <a href="https://ncirs.org.au/ncirs-study-confirms-decline-childhood-vaccination-coverage-throughout-covid-19-pandemic">routine whooping cough vaccinations</a> at the height of the pandemic may mean Australia is more vulnerable now. Reduced immunity in the population could be one of the reasons we’re seeing a rise in whooping cough cases in Australia and other countries including the <a href="https://www.gov.uk/government/publications/pertussis-epidemiology-in-england-2024/confirmed-cases-of-pertussis-in-england-by-month">United Kingdom</a> and the <a href="https://www.nyc.gov/assets/doh/downloads/pdf/han/advisory/2024/han-advisory-5.pdf">United States</a>.</p> <p>In Australia, cases have been particularly high during this outbreak in children aged 10–14.</p> <h2>A potential superbug</h2> <p>Over the past two decades, whooping cough has been getting better at evading vaccines and antibiotics. Most vaccines used in Australia and other developed countries stimulate your immune system to recognise and target <a href="https://immunisationhandbook.health.gov.au/contents/vaccine-preventable-diseases/pertussis-whooping-cough">three to five components</a> of the bacteria.</p> <p>Over time, the bacteria that causes whooping cough has been slowly acquiring mutations in these genes. These mutations make the bacteria look slightly different to the one used in the vaccine, helping it better hide from the immune system.</p> <p>Most of these changes were small. But in 2008, a new strain appeared in Australia that no longer produced <a href="https://wwwnc.cdc.gov/eid/article/20/4/13-1478_article">pertactin</a>, one of the components targeted by the vaccine. This means your immune system, like a detective, has one less clue to recognise the bacteria.</p> <p>This new strain rapidly increased from <a href="https://wwwnc.cdc.gov/eid/article/25/6/18-0240_article">5% of strains found in 2008</a>, to become the dominant strain in less than ten years, making up <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6537726/">90% of strains</a> by 2017. This pertactin-negative strain was shown to survive better in <a href="https://pubmed.ncbi.nlm.nih.gov/26432908/">vaccinated mice</a> and may have contributed to the high number of cases in the 2008–12 outbreak.</p> <p>Worryingly, since 2013, <a href="https://www.cdc.gov/drugresistance/biggest-threats.html">antibiotic-resistant strains</a> of whooping cough have become <a href="https://www.tandfonline.com/doi/full/10.1080/22221751.2019.1587315">widespread in China</a>. While there are other antibiotics available, these are not recommended for infants <a href="https://www.health.nsw.gov.au/Infectious/whoopingcough/Pages/workers-managing-cases.aspx">younger than two months</a> (the age group at most risk of serious disease). These resistant strains are increasingly <a href="https://wwwnc.cdc.gov/eid/article/26/10/20-1035_article">spreading through Asia</a> but are not yet in Australia.</p> <h2>What next?</h2> <p>It’s too early to know how big this outbreak will be or what strains are responsible for it. Greater tracking of whooping cough strains, like we do with COVID, is needed to inform future vaccine design and treatments.</p> <p>Importantly, although the bacteria is evolving, current vaccines are still very effective at preventing serious disease and reducing transmission. They remain our best tool to limit this outbreak.</p> <p>To protect oneself, vulnerable newborns, and the wider community, everyone should ensure they are up-to-date with their <a href="https://immunisationhandbook.health.gov.au/contents/vaccine-preventable-diseases/pertussis-whooping-cough">whooping cough vaccinations</a>. You can check this with your GP if you’re not sure. And anyone with cold or flu-like symptoms should <a href="https://ncirs.org.au/ncirs-fact-sheets-faqs/pertussis">stay away</a> from infants.<!-- Below is The Conversation's page counter tag.

Accused mushroom killer moved to protected unit over safety fears

<p>Erin Patterson, accused of poisoning three elderly individuals and attempting to murder several others, finds herself secluded within the confines of a protected unit in a Victorian prison. The move, reportedly necessitated by safety concerns, places Patterson away from the general prison population, reflecting the gravity of the allegations against her.</p> <p>According to sources cited by <a href="https://www.heraldsun.com.au/truecrimeaustralia/the-mushroom-ccok/accused-mushroom-murderer-in-jail-unit-with-pedophile-rapist/news-story/824c4f35c9d9b8f7553af2704836ea82" target="_blank" rel="noopener">the Herald Sun</a>, Patterson now resides in the protected wing of the Dame Phyllis Frost Centre, a correctional facility in Victoria. The decision to relocate her stems from fears that she may face harm from fellow inmates due to the nature of her alleged crimes.</p> <p>The <em>Herald's</em> insider disclosed, "If Erin got out of protection, the girls would hurt her."</p> <p>Allegations of her involvement in the deaths of three elderly individuals have evidently rendered her a target among fellow inmates, necessitating stringent security measures.</p> <p>“She allegedly killed three elderly people," the source continued. “There’s a rule, you don’t touch the elderly and you don’t touch babies so because of that, you go into protection."</p> <p>Patterson stands accused of several crimes, including the murder of her former in-laws, Don and Gail Patterson, alongside Gail's sister Heather Wilkinson. Their deaths, following the consumption of a meal containing deadly mushrooms at Patterson's residence in Leongatha, shook the community.</p> <p>Furthermore, Patterson faces charges of attempted murder, notably targeting her ex-husband Simon and Heather Wilkinson's husband Ian, with the alleged attempts spanning over various dates.</p> <p>As Patterson awaits her court appearance scheduled for May, the case continues to captivate public attention. In the coming months, the court will delve deeper into the intricacies of the case, striving to uncover the truth behind the allegations.</p> <p><em>Image: News.com.au</em></p>

Young musician dies weeks after writing final song

<p>Cat Janice has died aged 31 with her family by her side.</p> <p>The young musician, who had a large following on TikTok, had been battling cancer since January 2022 when doctors diagnosed her with sarcoma, a rare malignant tumour. </p> <p>She was declared cancer-free on July 22 that same year, following extensive surgery, chemo and radiation therapy. </p> <p>The mum-of-one was sadly re-diagnosed with cancer in June last year and despite fighting hard in the second round of her treatments, Janice told fans in January that her cancer "won" and that she "fought hard but sarcomas are too tough".</p> <p>Janice's family have announced her passing in a statement shared to her Instagram. </p> <p>"From her childhood home and surrounded by her loving family, Catherine peacefully entered the light and love of her heavenly creator," they said. </p> <p>"We are eternally thankful for the outpouring of love that Catherine and our family have received over the past few months."</p> <p>Before she died, Janice publicly announced that all her music would be signed over to her 7-year-old son, Loren, to support him in the future. </p> <p>Just weeks before her death, she released her final song <em>Dance You Outta My Head </em> in the hope it would spread "joy and fun". </p> <p>"My last joy would be if you pre saved my song 'Dance You Outta My Head' and streamed it because all proceeds go straight to my 7-year-old boy I'm leaving behind," she said, before the song was released. </p> <p>The song went viral, and took he number one spot in several countries and the number five spot on the Apple Itunes globally.</p> <p>Her family have said that the love she received for her final song, was unbelievable parting gift she could have ever received.</p> <p>"Cat saw her music go places she never expected and rests in the peace of knowing that she will continue to provide for her son through her music. This would not have been possible without all of you."</p> <p><em>Images: Instagram</em></p>

What ‘psychological warfare’ tactics do scammers use, and how can you protect yourself?

<p><em><a href="https://theconversation.com/profiles/mike-johnstone-106590">Mike Johnstone</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/georgia-psaroulis-1513050">Georgia Psaroulis</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>Not a day goes by without a headline <a href="https://www.vice.com/en/article/qjvaym/people-share-worst-scam-stories">about a victim being scammed</a> and losing money. We are constantly warned about new scams and staying safe from cybercriminals. Scamwatch has <a href="https://www.scamwatch.gov.au/research-and-resources/tools-resources/online-resources/spot-the-scam-signs">no shortage of resources</a>, too.</p> <p>So why are people still getting scammed, and sometimes spectacularly so?</p> <p>Scammers use sophisticated psychological techniques. They exploit our deepest human vulnerabilities and bypass rational thought to tap into our emotional responses.</p> <p>This “<a href="https://www.thecut.com/article/amazon-scam-call-ftc-arrest-warrants.html">psychological warfare</a>” coerces victims into making impulsive decisions. Sometimes scammers spread their methods around many potential victims to see who is vulnerable. Other times, criminals focus on a specific person.</p> <p>Let’s unpack some of these psychological techniques, and how you can defend against them.</p> <h2>1. Random phone calls</h2> <p>Scammers start with small requests to establish a sense of commitment. After agreeing to these minor requests, we are more likely to comply with larger demands, driven by a desire to act consistently.</p> <p>The call won’t come from a number in your contacts or one you recognise, but the scammer may pretend to be someone you’ve engaged to work on your house, or perhaps one of your children using a friend’s phone to call you.</p> <p>If it is a scammer, maybe keeping you on the phone for a long time gives them an opportunity to find out things about you or people you know. They can use this info either immediately or at a later date.</p> <h2>2. Creating a sense of urgency</h2> <p>Scammers fabricate scenarios that require immediate action, like claiming a bank account is at risk of closure or an offer is about to expire. This tactic aims to prevent victims from assessing the situation logically or seeking advice, pressuring them into rushed decisions.</p> <p>The scammer creates an artificial situation in which you are frightened into doing something you wouldn’t ordinarily do. Scam calls <a href="https://theconversation.com/we-have-filed-a-case-under-your-name-beware-of-tax-scams-theyll-be-everywhere-this-eofy-162171">alleging to be from the Australian Tax Office</a> (ATO) are a great example. You have a debt to pay (apparently) and things will go badly if you don’t pay <em>right now</em>.</p> <p>Scammers play on your emotions to provoke reactions that cloud judgement. They may threaten legal trouble to instil fear, promise high investment returns to exploit greed, or share fabricated distressing stories to elicit sympathy and financial assistance.</p> <h2>3. Building rapport with casual talk</h2> <p>Through extended conversation, scammers build a psychological commitment to their scheme. No one gets very far by just demanding your password, but it’s natural to be friendly with people who are friendly towards us.</p> <p>After staying on the line for long periods of time, the victim also becomes cognitively fatigued. This not only makes the victim more open to suggestions, but also isolates them from friends or family who might recognise and counteract the scam.</p> <h2>4. Help me to help you</h2> <p>In this case, the scammer creates a situation where they help you to solve a real or imaginary problem (that they actually created). They work their “IT magic” and the problem goes away.</p> <p>Later, they ask you for something you wouldn’t normally do, and you do it because of the “social debt”: they helped you first.</p> <p>For example, a hacker might attack a corporate network, causing it to slow down. Then they call you, pretending to be from your organisation, perhaps as a recent hire not yet on the company’s contact list. They “help” you by turning off the attack, leaving you suitably grateful.</p> <p>Perhaps a week later, they call again and ask for sensitive information, such as the CEO’s password. You <em>know</em> company policy is to not divulge it, but the scammer will ask if you remember them (of course you do) and come up with an excuse for why they really need this password.</p> <p>The balance of the social debt says you will help them.</p> <h2>5. Appealing to authority</h2> <p>By posing as line managers, officials from government agencies, banks, or other authoritative bodies, scammers exploit our natural tendency to obey authority.</p> <p>Such scams operate at varying levels of sophistication. The simple version: your manager messages you with an <em>urgent</em> request to purchase some gift cards and send through their numbers.</p> <p>The complex version: your manager calls and asks to urgently transfer a large sum of money to an account you don’t recognise. You do this because <a href="https://www.wsj.com/articles/fraudsters-use-ai-to-mimic-ceos-voice-in-unusual-cybercrime-case-11567157402">it sounds exactly</a> like your manager on the phone – but the scammer <a href="https://www.forbes.com/sites/thomasbrewster/2021/10/14/huge-bank-fraud-uses-deep-fake-voice-tech-to-steal-millions/?sh=1329b80e7559">is using a voice deepfake</a>. In a recent major case in Hong Kong, such a scam even involved a <a href="https://edition.cnn.com/2024/02/04/asia/deepfake-cfo-scam-hong-kong-intl-hnk/index.html">deepfake video call</a>.</p> <p>This is deeply challenging because artificial intelligence tools, such as Microsoft’s VALL-E, can create <a href="https://arstechnica.com/information-technology/2023/01/microsofts-new-ai-can-simulate-anyones-voice-with-3-seconds-of-audio/">a voice deepfake</a> using just three seconds of sampled audio from a real person.</p> <h2>How can you defend against a scam?</h2> <p>First and foremost, <strong>verify identity</strong>. Find another way to contact the person to verify who they are. For example, you can call a generic number for the business and ask to be connected.</p> <p>In the face of rampant voice deepfakes, it can be helpful to <strong>agree on a “safe word” with your family members</strong>. If they call from an unrecognised number and you don’t hear the safe word just hang up.</p> <p>Watch out for <strong>pressure tactics</strong>. If the conversation is moving too fast, remember that someone else’s problem is not yours to solve. Stop and run the problem past a colleague or family member for a sanity check. A legitimate business will have no problem with you doing this.</p> <p>Lastly, if you are not sure about even the slightest detail, the simplest thing is to hang up or not respond. If you really owe a tax debt, the ATO will write to you.<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/223959/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/mike-johnstone-106590"><em>Mike Johnstone</em></a><em>, Security Researcher, Associate Professor in Resilient Systems, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/georgia-psaroulis-1513050">Georgia Psaroulis</a>, Postdoctoral research fellow, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan 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.

What is doxing, and how can you protect yourself?

<p><em><a href="https://theconversation.com/profiles/rob-cover-13135">Rob Cover</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>The Australian government has brought forward <a href="https://www.theguardian.com/australia-news/2024/feb/12/albanese-government-to-propose-legislation-to-crack-down-on-doxing">plans to criminalise doxing</a>, bringing nationwide attention to the harms of releasing people’s private information to the wider public.</p> <p>The government response comes after the <a href="https://www.smh.com.au/national/hundreds-of-jewish-creatives-have-names-details-taken-in-leak-published-online-20240208-p5f3if.html">public release of almost 600 names</a> and private chat logs of a WhatsApp group of Australian Jewish creative artists discussing the Israel-Hamas war.</p> <p>As a result, some of the people whose details were leaked claim they were harassed, <a href="https://www.theguardian.com/australia-news/2024/feb/09/josh-burns-jewish-whatsapp-group-channel-publication-israel-palestine-clementine-ford">received death threats</a> and even had to go into hiding.</p> <p>While we wait for <a href="https://www.smh.com.au/national/australia-news-live-federal-laws-on-doxxing-to-be-brought-forward-anniversary-of-stolen-generations-apology-20240213-p5f4eh.html?post=p55nen#p55nen">new penalties</a> for doxers under the federal Privacy Act review, understanding doxing and its harms can help. And there are also steps we can all take to minimise the risk.</p> <h2>What is doxing?</h2> <p><a href="https://www.kaspersky.com/resource-center/definitions/what-is-doxing">Doxing</a> (or doxxing) is releasing private information — or “docs”, short for documents — online to the wider public without the user’s consent. This includes information that may put users at risk of harm, especially names, addresses, employment details, medical or financial records, and names of family members.</p> <p>The Australian government <a href="https://ministers.ag.gov.au/media-centre/transcripts/media-conference-parliament-house-13-02-2024">currently defines doxing</a> as the “malicious release” of people’s private information without their consent.</p> <p>Doxing began as a form of unmasking anonymous users, trolls and those using hate speech while <a href="https://www.theatlantic.com/technology/archive/2022/04/doxxing-meaning-libs-of-tiktok/629643/">hiding behind a pseudonym</a>. Recently, it has become a weapon for online abuse, harassment, hate speech and adversarial politics. It is often the outcome of online arguments or polarised public views.</p> <p>It is also becoming more common. Although there is no data for Australia yet, according to media company <a href="https://www.safehome.org/family-safety/doxxing-online-harassment-research/">SafeHome.org</a>, about 4% of Americans report having been doxed, with about half saying their private emails or home addresses have been made public.</p> <p>Doxing is a crime in some countries such as the Netherlands and South Korea. In other places, including Australia, privacy laws haven’t yet caught up.</p> <h2>Why is doxing harmful?</h2> <p>In the context of the <a href="https://theconversation.com/au/topics/israel-hamas-war-146714">Israel-Hamas war</a>, doxing has affected <a href="https://www.haaretz.com/world-news/asia-and-australia/2024-02-06/ty-article/death-threats-boycotts-target-jewish-creatives-in-australia/0000018d-7e43-d636-adef-7eefae580000">both Jewish</a> and <a href="https://edition.cnn.com/2023/10/15/business/palestinian-americans-activists-doxxing/index.html">pro-Palestinian communities and activists</a> in Australia and abroad.</p> <p>Doxing is harmful because it treats a user as an object and takes away their agency to decide what, and how much, personal information they want shared with the wider public.</p> <p>This puts people at very real risk of physical threats and violence, particularly when public disagreement becomes heated. From a broader perspective, doxing also damages the digital ecology, reducing people’s ability to freely participate in public or even private debate through social media.</p> <p>Although doxing is sometimes just inconvenient, it is often used to publicly shame or humiliate someone for their private views. This can take a toll on a person’s mental health and wellbeing.</p> <p>It can also affect a person’s employment, especially for people whose employers require them to keep their attitudes, politics, affiliations and views to themselves.</p> <p>Studies have shown doxing particularly impacts <a href="https://journals.sagepub.com/doi/full/10.1177/0306422015605714">women</a>, including those using dating apps or experiencing family violence. In some cases, children and family members have been threatened because a high-profile relative has been doxed.</p> <p>Doxing is also harmful because it oversimplifies a person’s affiliations or attitudes. For example, releasing the names of people who have joined a private online community to navigate complex views can represent them as only like-minded stereotypes or as participants in a group conspiracy.</p> <h2>What can you do to protect yourself from doxing?</h2> <p>Stronger laws and better platform intervention are necessary to reduce doxing. Some experts believe that the fear of <a href="https://dl.acm.org/doi/abs/10.1145/3476075">punishment</a> can help shape better online behaviours.</p> <p>These punishments may include criminal <a href="https://www.esafety.gov.au/report/what-you-can-report-to-esafety">penalties</a> for perpetrators and <a href="https://www.theaustralian.com.au/breaking-news/doxxing-attack-on-jewish-australians-prompts-call-for-legislative-change/news-story/9a2f3615dbf5594fb521a8959739e1f8#:%7E:text=Alongside%20legislative%20reform%2C%20the%20ECAJ,information%2C%E2%80%9D%20Mr%20Aghion%20said.">deactivating social media accounts</a> for repeat offenders. But better education about the risks and harms is often the best treatment.</p> <p>And you can also protect yourself without needing to entirely withdraw from social media:</p> <ol> <li> <p>never share a home or workplace address, phone number or location, including among a private online group or forum with trusted people</p> </li> <li> <p>restrict your geo-location settings</p> </li> <li> <p>avoid giving details of workplaces, roles or employment on public sites not related to your work</p> </li> <li> <p>avoid adding friends or connections on social media services of people you do not know</p> </li> <li> <p>if you suspect you risk being doxed due to a heated online argument, temporarily shut down or lock any public profiles</p> </li> <li> <p>avoid becoming a target by pursuing haters when it reaches a certain point. Professional and courteous engagement can help avoid the anger of those who might disagree and try to harm you.</p> </li> </ol> <p>Additionally, hosts of private online groups must be very vigilant about who joins a group. They should avoid the trap of accepting members just to increase the group’s size, and appropriately check new members (for example, with a short survey or key questions that keep out people who may be there to gather information for malicious purposes).</p> <p>Employers who require their staff to have online profiles or engage with the public should provide information and strategies for doing so safely. They should also provide immediate support for staff who have been doxed.<!-- Below is The Conversation's page counter tag.

"Worth it": Insane amount woman spends to clone dead cat

<p>Kelly Anderson from Texas, US was devastated when she lost her "soulmate" cat Chai more than four years ago. </p> <p>Not long after, in what she calls "fate", Anderson decided to clone her beloved pet, a process which cost her a whopping $USD25,000 ($AUD38,000).</p> <p>"It was just one of those moments where I had been talking about cloning a few weeks before and fate kicked in," she told <em>Weekend Today</em>.</p> <p>"I remembered the conversation and decided to clone."</p> <p>The process took about four years, which is roughly twice the average time it takes to clone a pet. </p> <p>"It was not money that I had come easily to me but it was a very important process for me to do," she said.</p> <p>"It was 100 per cent worth it. The process saved my life."</p> <p>Anderson added that Belle, the successfully cloned cat, has grown to be as "bold, bossy, sassy" as Chai, and their personalities have become more alike. </p> <p>Despite the similarities, Anderson said that she doesn't set any expectations on Belle to be Chai's replacement. </p> <p>"I would still say she's very much her own cat and I treat her that way. I always try to treat them as individuals.</p> <p>"I never wanted to put expectations on Belle to be Chai. But I would say that they're very similar in a lot of ways."</p> <p><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">According to</span><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;"> </span><em><a href="https://www.bbc.com/news/business-60924936" target="_blank" rel="noopener">BBC</a>, </em>the process itself involves extracting DNA from the pet to be cloned, then injecting that into a donor egg that has had its genetic material removed. The egg then grows into an embryo before being implanted into a surrogate mother, who then gives birth to the kitten. </p> <p>Pet cloning has become an increasingly popular practice, , despite how controversial and expensive it is, with celebrities like Barbra Streisand and Simon Cowell using the process to clone their own beloved pets. </p> <p>Anderson, who decided to document her story on social media added that people have mixed reactions to the process. </p> <p>"I think there's people who are fascinated and don't even realise that we're cloning animals ... so a lot of people are learning about cloning," she said. </p> <p>"But a lot of people also have opinions. So it's a mixed bag."</p> <p><em>Images: Weekend Today</em></p> <p> </p>

Are catnip and treats like it safe for cats? Here’s how they affect their minds and moods

<p><em><a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/anne-quain-12802">Anne Quain</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Cats kept indoors can <a href="https://safeandhappycats.com.au/">live a good life</a> when they get access to a variety of positive experiences. Examples include performing natural behaviours, feeling safe at home and using their full sensory capabilities, including their sense of smell.</p> <p>Plants such as catnip, cat thyme and silver vine are potent smelly stimulants that can affect cat minds and moods.</p> <p>Ever wondered if these mind-altering substances are safe gifts for our feline friends? And importantly, is it OK to provide these, or is offering catnip to a cat like offering alcohol to a child?</p> <h2>Catnip, cat thyme and silver vine, oh my!</h2> <p>Owners who are concerned about their cats feeling bored and frustrated might offer them fresh or dried catnip (<em>Nepeta cataria</em>), silver vine (<em>Actinidia polygama</em>), cat thyme (<em>Teucrium marum</em>) or other plant materials such as valerian (<em>Valeriana officinalis</em>) and Tatarian honeysuckle (<em>Lonicera tatarica</em>). These last couple <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">could offer an alternative</a> if your cat doesn’t respond to catnip.</p> <p>Toys filled with the leaves or extracts of these plants can cause apparently euphoric behaviour in domestic cats (as well as big cats like leopards and jaguars). Not all cats respond this way to these smells, which is <a href="https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-022-01369-1">believed to have a genetic basis</a>.</p> <h2>Are these treats safe for cats?</h2> <p>Cats have a highly developed sense of smell. Some plants release chemical compounds to deter insects or to attract predators of insects that might otherwise destroy them. This includes <a href="https://www.science.org/doi/10.1126/sciadv.aba0721">nepetalactone</a>, an ingredient isolated from catnip and silver vine.</p> <p>Indeed, <a href="https://www.science.org/content/article/why-cats-are-crazy-catnip">it has been argued </a> that exposure to nepetalactone leads to an increase in feel-good hormones in cats. It may also act as a <a href="https://www.science.org/doi/10.1126/sciadv.abd9135">natural mosquito repellent</a> (note that it does not repel all mosquitoes and is not effective for flea or tick control).</p> <p>This may be why sniffing catnip, silver vine and some other plants causes cats to roll on their backs and rub their chins, cheeks and bodies on the plants. Other <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">observed behaviours</a> include: licking, shaking their head while carrying plant material in their mouth, drooling, kicking the plant material with their hind feet, and a “wavelike” motion of the skin over their backs as muscles contract and relax.</p> <p>These responses <a href="https://bmcvetres.biomedcentral.com/articles/10.1186/s12917-017-0987-6">generally don’t last long</a>, usually seconds to minutes, before cats relax or resume their normal behaviour.</p> <p>Rather than becoming addicted to these substances, cats are more likely to become habituated and desensitised, with the plants having less effect over time.

How to protect yourself from cyber-scammers over the festive period

<p><em><a href="https://theconversation.com/profiles/rachael-medhurst-1408437">Rachael Medhurst</a>, <a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a></em></p> <p>The festive season is a time for joy, family and festive cheer. However, it’s also a prime target for cybercriminals. As online shopping ramps up, so does the risk of falling prey to cyber-attacks. That’s why it’s crucial to be extra vigilant about your <a href="https://blog.tctg.co.uk/12-cyber-security-tips-of-christmas">cybersecurity</a> during this time.</p> <p>Here are some essential tips to safeguard yourself and your data during the festive period:</p> <h2>Phishing</h2> <p>Phishing is when criminals use scam emails, text messages or phone calls to trick their victims. Their <a href="https://www.ncsc.gov.uk/collection/phishing-scams">goal</a> is often to make you visit a certain website, which may download a virus on to your computer, or steal bank details or other personal data.</p> <p>This type of scam tends to <a href="https://www.egress.com/blog/phishing/holiday-phishing-scam-guide">increase</a> at this time due to the amount of people having bought or received new gadgets and technology.</p> <p>Look out for there being no direct reference to your name in any communications, with wording such as “Dear Sir/Madam” or other terms such as “valued customer” being used instead. Grammar and spelling mistakes are also often present.</p> <p>Be wary of any suspicious links or attachments within emails too, and don’t click them. It’s better to contact the company directly to check if the message is genuine. You can also <a href="https://www.ncsc.gov.uk/collection/phishing-scams">report</a> suspicious messages and phishing scams to the government’s National Cyber Security Centre.</p> <h2>Shopping safely online</h2> <p>The convenience of online shopping is undeniable, especially during the festive season. However, it’s crucial to prioritise your security when buying online.</p> <p>Before entering your personal and financial information on any website, ensure it’s legitimate and secure. Look for the “https” in the address bar and a <a href="https://theconversation.com/the-vast-majority-of-us-have-no-idea-what-the-padlock-icon-on-our-internet-browser-is-and-its-putting-us-at-risk-216581">padlock</a> icon, which indicates a secure and encrypted connection.</p> <p>When creating passwords for online shopping accounts, use strong, unique combinations of letters, numbers and symbols. Avoid using the same password for multiple accounts, as a breach on one site could compromise all your others.</p> <p>As with shopping in the real world, be cautious when encountering offers that are significantly below usual prices or which make extravagant promises. Always conduct thorough research on the seller and product before making a purchase. If a deal seems too good to be true, it probably is.</p> <p>And if you are out shopping in towns or city centres, there will often be a large number of public wifi options available to you. However, criminals can intercept the data that is transferred across such open and unsecured wifi. So, avoid using public wifi where possible, especially when conducting any financial transactions.</p> <h2>Social media</h2> <p>While social media platforms provide people with a means to keep in touch with family and friends over the festive period, they are often a goldmine for <a href="https://www.which.co.uk/consumer-rights/advice/how-to-spot-a-social-media-scam-aMtwF3u1XKGt">scams</a> and malware (software designed to disrupt, damage or gain unauthorised access to a computer). In the spirit of the festive season, people often share an abundance of personal information on social media, often without considering the potential consequences.</p> <p>This trove of data can make people vulnerable to cyber-attacks. Scammers can exploit this information to gain unauthorised access to social media accounts, steal personal information, or even commit identity theft. To protect yourself, be mindful of what you share.</p> <p>Be wary when interacting with posts and direct messages, especially if they contain suspicious links or attachments. Before clicking on anything, hover over the link to verify its destination. If it shows a website you don’t recognise or seems unrelated to the message, do not click on it. If you receive a message from someone you know but the content seems strange or out of character, contact them directly through a trusted channel to verify its authenticity.</p> <p>Likewise, be wary of messages containing urgent requests for money or personal information from businesses. Genuine organisations will never solicit sensitive details through social media.</p> <p>There are many buy and sell platforms available on social media. But while such platforms can be a great place to find a unique gift, it is also important to remember that not all sellers may be legitimate. So, it’s vital that you don’t share your bank details. If the seller sends a link to purchase the item, do not use it. When meeting to collect an item, it’s generally safer to use cash rather than transferring funds electronically.</p> <figure><iframe src="https://www.youtube.com/embed/aO858HyFbKI?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Advice for staying safe online.</span></figcaption></figure> <h2>Package delivery scams</h2> <p>As well as being a time for giving and receiving gifts, the festive season is also ripe for cybercriminals to exploit the excitement surrounding <a href="https://www.citizensadvice.org.uk/about-us/about-us1/media/press-releases/scams-linked-to-parcel-deliveries-come-top-in-2023/">package deliveries</a>.</p> <p>Scammers often pose as legitimate delivery companies, sending emails or text messages claiming that a delivery attempt was unsuccessful or requiring additional fees for processing, or even customs clearance. Typically, these messages contain links or phone numbers that, when clicked or called, lead to fake websites or automated phone systems designed to collect personal information or payments.</p> <p>To protect yourself, always verify the legitimacy of any delivery notifications you receive. Check the sender’s email address or phone number against the official contact information for the delivery company. If the information doesn’t match or seems suspicious, don’t click any links or provide personal details.</p> <p>Legitimate delivery companies will never ask for upfront payment or sensitive information through unsolicited messages or calls.</p> <p>Remember, cybercriminals are skilled at manipulating the festive spirit to their advantage. Stay vigilant, exercise caution, and don’t let your excitement for gifts and deliveries compromise your cybersecurity.<!-- Below is The Conversation's page counter tag.

“He gave his life to protect his siblings”: Tragic end for third child in shed fire

<p>In a heart-wrenching turn of events, the devastating shed fire that took place in Geelong, Victoria, on the weekend has claimed the life of a brave young hero.</p> <p>Isaac, the four-year-old boy who had been fighting for his life after the fire that tragically claimed the lives of two of his siblings, Ashlynn, aged 18 months, and Saige, just three years old, has succumbed to his injuries. The incident took place on a quiet Sunday morning in Corio, leaving the local community in shock and mourning.</p> <p>The children had been inside a shed on their family's property when the fire erupted, turning a normal day into an unimaginable nightmare. Despite the heroic efforts of Isaac, who valiantly shielded his younger siblings from the flames, the consequences were too grave for him to overcome. The fire rapidly consumed the shed, taking the lives of Ashlynn and Saige before they could be rescued.</p> <p>Isaac's father, Kane McGregor, described the extent of his son's injuries, with third-degree burns covering a staggering 82 percent of his young body. As if this wasn't enough, Isaac began showing signs of kidney and liver failure, all stemming from his courageous act to protect his siblings during the harrowing incident.</p> <p>“[Jasmine, their mother] said once she finally got the couch moved and grabbed Mavis first, Isaac had the other two huddled under him so they didn’t burn,” McGregor said. “What four-year-old huddles over their two little siblings? I couldn’t be any prouder of him.”</p> <p>Tragically, despite the valiant efforts of medical professionals, young Isaac couldn't overcome the devastating injuries he sustained.</p> <p>The loss of this young hero has left a deep void in the hearts of those who followed his courageous story. A <a href="https://www.gofundme.com/f/in-memory-of-Issac-saige-and-ashlynn" target="_blank" rel="noopener">GoFundMe page</a>, originally organised to raise funds for the children's medical expenses and support, posted an update following Isaac's death. It read, "Issac sadly grew his wings and reunited with his baby brother and sister. He will always be remembered as the heroic young boy who gave his life trying to protect his siblings."</p> <p>Mavis, Isaac's six-year-old sister, was the sole survivor among the siblings, though she, too, suffered severe injuries, with third-degree burns covering 30 percent of her body. She is currently in critical condition and is set to undergo surgery to address her injuries. Despite the physical and emotional trauma that Mavis has endured, there is hope that she will recover and heal in due course.</p> <p>The circumstances surrounding the fire remain unclear, and an investigation is underway to determine the exact cause of the tragedy. A couch inside the shed, initially used as a dog bed, became the source of the fire that swiftly engulfed the structure. The local authorities are diligently preparing a report for the Coroner to gain a deeper understanding of the events leading up to this devastating incident.</p> <p><em>Image: GoFundMe</em></p>

Top tips to protect your outdoor furniture

<p>If you have outdoor furniture, it’s important to look after it properly so it will stay in good condition over the years. Remember to invest in UV and water-resistant<strong> </strong>chair covers<span style="text-decoration: underline;"><strong> </strong></span>and pillows in order to ensure you can enjoy your outdoor furniture without the hassle of replacing all your items. Here’s how to care for your furniture.</p> <p><strong>1. Wooden</strong></p> <p>To get your wooden outdoor furniture ready for use, clean with hot soapy water or a hardwood cleaning fluid at the beginning of the season. If the furniture is very dirty then you can lightly sand the furniture after cleaning. It is a good idea to oil or paint your outdoor furniture after cleaning.</p> <p>If you want your furniture to age naturally, then oil the furniture with two coats and leave to dry for 48 hours. Use hardwood oil for eucalyptus and teak oil for teak furniture. If you want your outdoor furniture to look new, then use a stained oil. If you want to completely transform your furniture then paint with 2-3 coats and it should last for roughly three years.</p> <p><strong>2. Metal</strong></p> <p>When you wash your metal outdoor furniture be sure to clean it with a non-abrasive cloth. If the furniture is made from steel, you need to treat any scratches that expose the bare metal underneath to prevent rust. If rust has already set it on your furniture, remove it using steel wool and then touch it up using an exterior metal paint of the same colour.</p> <p>If your furniture is made from aluminium, it won’t rust but it may suffer from aluminium oxidation. This won’t decrease the strength of the furniture but it will change the colour of the metal over time. To prevent this from happening, make sure you clean it regularly and store it away or keep it covered during the winter months.</p> <p>One tip to keep your metal furniture in pristine condition is to polish it with car wax after you have finished cleaning it. The wax will help the furniture be more water resistant.</p> <p><strong>3. Rattan</strong></p> <p>Synthetic rattan is UV and weather-resistant so it won’t be as worn out by the weather conditions. Whenever it needs a refresh, wash with soapy water. It is important to keep an eye on the frame underneath as if that is made from steel rather than aluminium, you will need to abide by the metal care rules.</p> <p><strong>4. Resin</strong></p> <p>Resin outdoor furniture is fairly easy to look after. Wash it regularly with soap to keep it in great condition. If there is dirt or stains that are particularly hard to get out, then wash your furniture with a pressure washer.</p> <p><em>Image credits: Getty Images</em></p>

The strange history of these 5 common superstitions

<p><strong>Where superstitions come from</strong></p> <p>You probably engage in many of these superstitions as second nature, but have you ever thought about where they come from?</p> <p><strong>Superstition: Black cats are bad omens</strong></p> <p><span style="text-decoration: underline;"><em>The backstory</em></span>: Despite centuries of royal treatment (Egyptians worshipped them; the Norse goddess Freya rode in a chariot pulled by them), cats took a big hit to their reputation in the 1200s, when Pope Gregory IX, waging a culture war on pagan symbols, damned cats as servants of Satan.</p> <p>As a result, cats – especially black ones – were killed across Europe. One unintended consequence, according to some historians: The cat-deprived continent may have allowed disease-carrying rodents to flourish and spread the bubonic plague of 1348.</p> <p>Rumours that the feline’s fangs and fur were venomous persisted, and by the witch-hunting days of the 1600s, many Puritans believed black cats to be “familiars” – supernatural demons that serve witches – and avoided them (to borrow an apt phrase) like the plague.</p> <p><strong>Superstition: Never walk under a ladder</strong></p> <p><span style="text-decoration: underline;"><em>The backstory</em></span>: Depending on your background, a ladder leaning against a wall can represent an honest day’s work, a textbook geometry problem, or a symbol of the Holy Trinity that, if breached, will damn your soul. That last bit is what some ancient Christians believed – that any triangle represented the Trinity, and disrupting one could summon the Evil One.</p> <p>These days, our under-ladder phobia is a smidge more practical: Avoid it because you might get beaned by falling tools, debris, or an even less lucky human.</p> <p><strong>Superstition: Break a mirror and see seven years of bad luck</strong></p> <p><span style="text-decoration: underline;"><em>The backstory</em></span>: Numerous ancient cultures agree: Your reflection doesn’t just reveal whether you’re having a bad hair day – it also holds a piece of your soul. To break a mirror, then, is to fracture your very essence, leaving you vulnerable to bad luck.</p> <p>So why should the sentence last seven years? Some writers cite the ancient Romans, who are said to have believed that the human body and soul fully regenerate every seven years. Any poor pleb who fractured his or her soul in the looking glass would therefore have to endure the bad karma until the soul renewed again.</p> <p><strong>Superstition: A full moon brings out the crazies</strong></p> <p><span style="text-decoration: underline;"><em>The backstory</em></span>: Ever wonder where the word lunatic came from? Look no further than luna, the Latin word for the moon. Many Greeks knew that the moon and its goddess, Luna, held the tides in their thrall, and Aristotle considered the human brain – the “moistest” organ – particularly susceptible to Luna’s pull.</p> <p>Ancient physician Hippocrates agreed, writing, “One who is seized with terror, fright and madness during the night is being visited by the goddess of the moon.” Today, some emergency room workers still believe the full moon means trouble.</p> <p><strong>Superstition: Say “God bless you” after a sneeze or risk something worse than a cold</strong></p> <p><span style="text-decoration: underline;"><em>The backstory</em></span>: You’ve probably heard the myth that a sneeze stops the heart (it doesn’t) or separates body from soul (science declines to comment there). But to explain the ritual of post-sneeze “blessing,” we can look to another pope.</p> <p>During the first recorded plague pandemic, in the sixth century, severe sneezing often portended sudden death. As a desperate precaution, Pope Gregory I supposedly asked followers to say “God bless you” every time someone sneezed. Today, it’s just polite.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/culture/this-is-the-history-behind-these-5-common-superstitions" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

It is a vital part of many ecosystems and cultures. Yet human activities in the current era, sometimes called the “<a href="https://theconversation.com/did-the-anthropocene-start-in-1950-or-much-earlier-heres-why-debate-over-our-world-changing-impact-matters-209869">Anthropocene</a>”, are reshaping patterns of fire across the planet.</p> <p><a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">In our new research</a>, published in the Annual Review of Environment and Resources, we used satellite data to create global maps of where and how fires are burning. We calculated about 3.98 million square kilometres of Earth’s land surface burns each year. We also examined research spanning archaeology, climatology, ecology, Indigenous knowledge and paleoecology, to better understand the causes and consequences of fires.</p> <p>Our international team found strong evidence fires are burning in unexpected places, at unusual times and in rarely observed ways. These changes in fire patterns are threatening human lives and modifying ecosystems.</p> <p>But the future does not have to be bleak. There are many opportunities to apply knowledge and practice of fire to benefit people and nature.</p> <h2>Here’s how fire patterns are changing</h2> <p>Exploring multiple approaches and scales enables a deeper understanding of where, when and how fires burn.</p> <p>Satellite data provide evidence of changes in fire patterns at a global scale. <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020RG000726">Annual fire season length</a> increased by 14 days from 1979 to 2020 and <a href="https://www.nature.com/articles/s41586-021-04325-1">night fires</a>, which indicate fires that cannot be quickly controlled, increased in intensity by 7.2% from 2003 to 2020.</p> <p>Other changes are apparent only when we look at data from particular regions. An increase in fire size and the frequency of large fires has recently been observed in <a href="https://www.pnas.org/doi/abs/10.1073/pnas.2103135118">forests and woodlands of the western United States</a>. Meanwhile fire-dependent grasslands and savannahs across <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.14711">Africa</a> and <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL082327">Brazil</a> have experienced reductions in fire frequency.</p> <p>It’s also important to consider the timescale and type of fire when interpreting changes. In Australia, <a href="https://www.nature.com/articles/s41467-021-27225-4">satellite records show</a> the frequency of very large forest fires has increased over the past four decades. At longer time scales, <a href="https://link.springer.com/article/10.1007/s13280-020-01339-3">charcoal and pollen records</a> indicate the frequency of low-intensity fires <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">decreased in parts of southeastern Australia</a> following British colonisation in 1788.</p> <h2>Changes in fire affect air, land and water</h2> <p>Many animals and plants have evolved strategies that enable them to thrive under particular fire patterns. This means changes to fire characteristics can <a href="https://www.science.org/doi/10.1126/science.abb0355">harm populations and ecosystems</a>.</p> <p><a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/conl.12905">Large and intense fires</a> are reducing the available forest habitat preferred by the greater glider. But a <a href="https://theconversation.com/research-reveals-fire-is-pushing-88-of-australias-threatened-land-mammals-closer-to-extinction-185965">lack of fire can be problematic too</a>. Threatened species of native rodents can benefit from food resources and habitats that flourish shortly after fire.</p> <p>There is evidence that emissions from recent fires are already modifying the atmosphere. The historically exceptional 2019–20 Australian wildfires produced <a href="https://www.science.org/doi/10.1126/science.abe1415#:%7E:text=Intense%2C%20widespread%20bushfires%20in%20Australia,from%20a%20moderate%20volcanic%20eruption.">record-breaking levels of aerosols</a> over the Southern Hemisphere, as well as substantial carbon emissions.</p> <p>The <a href="https://www.nature.com/articles/s41893-020-00610-5">wildfire smoke-related health costs</a> of the 2019–20 wildfires in Australia included an estimated 429 smoke-related premature deaths as well as 3,230 hospital admissions for cardiovascular and respiratory disorders.</p> <p>Changes in fire patterns are modifying water cycles, too. In the western United States, <a href="https://www.pnas.org/doi/10.1073/pnas.2009717118">fires are reaching higher elevations</a> and having strong impacts on <a href="https://www.pnas.org/doi/10.1073/pnas.2200333119">snow</a> and water availability.</p> <p>New studies are revealing how the air, land and water that support life on Earth are connected by fires. Smoke plumes from the 2019–20 Australian wildfires transported nutrients to the Southern Ocean, resulting in <a href="https://www.nature.com/articles/s41586-021-03805-8">widespread phytoplankton blooms</a>.</p> <h2>Humans are responsible for the changes</h2> <p>Human drivers such as climate change, land use, fire use and suppression, and transportation and extinction of species <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">are causing shifts in fire patterns</a>.</p> <p>Increasing global temperatures and more frequent heatwaves and droughts increase the likelihood of fire by promoting hot, dry and windy conditions.

7 tips to help turn your cat into a friendly member of the family

<p><strong>How to make your cat love you</strong></p> <p>Getting a cat to be more affectionate is the yearning of many a pet owner. Some cats are antisocial when it comes to being picked up, cuddled or petted (much less sitting in a person’s lap). Other kitties are born loving this sort of attention.</p> <p>If you’re not lucky enough to have a cat who automatically seeks out your affection, trying to entice that reclusive furball to become your snuggle buddy may take some motivation and determination on your part. Your pet may never convert to a drooly lap cat, even after weeks of effort on your part, but at the very least you’ll probably strengthen your relationship with your cat.</p> <p><strong>Get the basics down</strong></p> <p>The initial stage of coaxing a cat into being more lovable is to let her recognise your positive intentions by dependably offering her good food, clean water, fun toys to play with and a litterbox that is cleaned regularly. When she’s happier, you’ll be happier, and these mutual good feelings will carry over into your relationship together.</p> <p>Spend extra time with your cat, letting her see you not as her owner but as her friend, meal provider and guardian. If she’s not coming up to you to say hi, be proactive: Walk over to her (as long as she’s not super-shy) and lavish affection on her. Once she gets used to all this attention, she might very well start seeking it out from you.</p> <p><strong>Be affectionate while feeding </strong></p> <p>While preparing her food (or making a production of opening that can of food), talk to your kitty. When she begins eating, gently stroke her a few times. This will help her associate being petted with a positive experience.</p> <p><strong>Be playful </strong></p> <p>Instead of trying to force a hug from your reluctant cat, play with her a little, maybe getting her to paw at a piece of string or chase after a laser pointer.</p> <p><strong>Try a little catnip</strong></p> <p>Bringing out a tin of catnip often brings timid felines out of their shells, and aloof cats sometimes become far friendlier under the influence of catnip.</p> <p><strong>Use the "slow blink"</strong></p> <p>Remember that using the “slow blink” as a non-verbal statement saying “I love you” will go a much longer way with your cat, versus a direct stare, which she may take as a threat.</p> <p><strong>Don't chase</strong></p> <p>Don’t try to push affection on your cat – for example, running after her. This might work with a dog, but chasing usually causes a scaredy cat to jolt off in another direction feeling victimised. And I should hope it goes without saying, but don’t punish or yell at your shy cat.</p> <p><strong>Give them a treat</strong></p> <p>Each time you share a session of tenderness with your cat, give her a treat. Let her see that this affectionate behaviour has its rewards.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/pets/7-tips-to-make-your-cat-more-friendly" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Finding a live brain worm is rare. 4 ways to protect yourself from more common parasites

<p><em><a href="https://theconversation.com/profiles/vincent-ho-141549">Vincent Ho</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p><a href="https://www.theguardian.com/australia-news/2023/aug/28/live-worm-living-womans-brain-australia-depression-forgetfulness">News reports</a> this morning describe how shocked doctors removed a live worm from a woman’s brain in a Canberra hospital last year. The woman had previously been admitted to hospital with stomach symptoms, dry cough and night sweats and months later experienced depression and forgetfulness that led to a brain scan.</p> <p>In the <a href="https://wwwnc.cdc.gov/eid/article/29/9/23-0351_article">case study</a> published in Emerging Infectious Diseases journal, doctors describe removing the live 8cm-long nematode (roundworm) from the brain of the 64-year-old woman who was immunosuppressed. The worm was identified as <em>O. robertsi</em> which is native to Australia, where it lives on carpet pythons. The woman may have come into contact with worm eggs via snake faeces while foraging for Warrigal greens to eat.</p> <p>It’s important to note this is an extremely rare event and headlines about brain worms can be alarming. But there are more common parasites which can infect your body and brain. And there are ways you can minimise your risks of being infected with one.</p> <h2>Common parasites and how they get in</h2> <p>Parasitic infection is extremely common. Arguably the most widespread type is pinworm (<em>Enterobius vermicularis</em> also called threadworm), which is thought to be present in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6522669/">over a billion people</a> worldwide, especially children. Pinworms grow to around 1cm in length and are specific to human hosts. They cause intense bottom itching and get passed from person-to-person. It’s a myth that you can get it from pets.</p> <p><a href="https://www.cdc.gov/parasites/giardia/pathogen.html#:%7E:text=Giardia%20duodenalis%20is%20a%20protozoan,Giard%20of%20Paris%20and%20Dr.">Giardia</a> (<em>Giardia duodenalis</em>) is also very common and can contaminate food, water and surfaces. This water-borne parasite is associated with poor sanitation and causes stomach symptoms like diarrhoea, cramps, bloating, nausea and fatigue. Giardia cysts (little sacs of immature parasite) spread disease and are passed out in faeces, where they can remain viable in the environment for months before being consumed by someone else. They can also be ingested via foods (such as sheep meat) that is raw or undercooked.</p> <p><a href="https://www.cdc.gov/dpdx/hookworm/index.html">Two types</a> of hookworm – <em>Necator americanis</em> and <em>Ancylostoma duadonale</em> – are found in soil. Only <em>Ancylostoma duodenale</em> is an issue in Australia and is typically found in <a href="https://www.cdc.gov/dpdx/hookworm/index.html">remote communities</a>.</p> <p>When a person is infected (usually via barefeet or contaminated footwear) these worms enter the bloodstream and then hit the lungs. From the bronchi in the upper lungs, they are swallowed with secretions. Once in the gut and small bowel they can <a href="https://www.who.int/news-room/fact-sheets/detail/soil-transmitted-helminth-infections#:%7E:text=Transmission,these%20eggs%20contaminate%20the%20soil.">cause anaemia</a> (low iron). This is because they are consuming nutrients and affecting iron absorption. They also release an anticoagulant that stops the human host’s blood clotting and causes tiny amounts of blood loss.</p> <p>Fortunately, these very common parasites do not infect the brain.</p> <p>Across the world, it’s estimated <a href="https://pubmed.ncbi.nlm.nih.gov/22491772/">30–50% of people</a> are infected with <em>Toxoplasma</em>. Most people will be asymptomatic but many carry the <a href="https://theconversation.com/one-in-three-people-are-infected-with-toxoplasma-parasite-and-the-clue-could-be-in-our-eyes-182418">signs of infection</a>.</p> <p>The parasites can remain in the body for years as tiny tissue cysts. These cysts can be found in brain, heart and muscle. Infants can be born with serious eye or brain damage if their mothers are infected during pregnancy. People with compromised immunity – such as from AIDS or cancer treatment – are also at risk of illness from infection via pet cats or uncooked meat.</p> <h2>Then there are tapeworms and amoebas</h2> <p>Tapeworms can infect different parts of the body including the brain. This is called <a href="https://www.cdc.gov/parasites/resources/pdf/npis_in_us_neurocysticercosis.pdf">neurocysticercosis</a> and is the leading cause of epilepsy worldwide. Neurocysticercosis is uncommon in the Western world and infection is usually via eating pork that is uncooked or prepared by someone who is infected with tapeworm (<em>Taenia solium</em>). It is more likely in locations where pigs have contact with human faeces via sewerage or waterways.</p> <figure class="align-right zoomable"><figcaption></figcaption></figure> <p>Tapeworm larvae can infect muscle and soft tissue. Brain tissue can provide a home for larvae because it is soft and easy to get to via blood vessels. Brain infection can cause headaches, dizziness, seizures, cognitive impairment and even dementia, due to an increase in <a href="https://www.cdc.gov/parasites/cysticercosis/gen_info/faqs.html">cerebral spinal fluid pressure</a>.</p> <p><em><a href="https://www.cdc.gov/parasites/naegleria/general.html">Naegleria fowleri</a></em> is an amoeba found in lakes, rivers and springs in warm climates including <a href="https://www.sahealth.sa.gov.au/wps/wcm/connect/public+content/sa+health+internet/public+health/water+quality/naegleria+fowleri#:%7E:text=How%20common%20are%20Naegleria%20fowleri,frequently%20found%20in%20the%20environment.">in Australia</a>. People swimming in infected waters can have the parasite enter their body through the nose. It then travels to the brain and destroys brain tissue. The condition is <a href="https://www.cdc.gov/parasites/naegleria/general.html#:%7E:text=Top%20of%20Page-,What%20is%20the%20death%20rate%20for%20an%20infected%20person%20who,States%20from%201962%20to%202022.">almost always fatal</a>.</p> <h2>Yikes! 4 ways to avoid parasitic infection</h2> <p>That all sounds very scary. And we know being infected by a snake parasite is very rare – finding one alive in someone’s brain is even rarer. But parasites are all around us. To minimise your risk of infection you can:</p> <p><strong>1.</strong> avoid undercooked or raw pork. Freezing meat first may reduce risks (though home freezers <a href="https://www.cdc.gov/parasites/trichinellosis/prevent.html">may not get cold enough</a>) and it must be cooked to a <a href="https://www.sciencedirect.com/science/article/pii/S0924224418301560#:%7E:text=and%20time%20conditions.-,Cooking%20at%20core%20temperature%2060%E2%80%9375%20%C2%B0C%20for%2015,relied%20upon%20in%20home%20situations.">high internal temperature</a>. Avoid pork if you are travelling in places with poor sanitation</p> <p><strong>2.</strong> avoid jumping or diving into warm fresh bodies of water, especially if they are known to carry <em>Naegleria fowleri</em>. Although only a <a href="https://www.cdc.gov/parasites/naegleria/graphs.html">handful of cases</a> are reported each year, you should assume it’s present</p> <p><strong>3.</strong> practise good <a href="https://www.cdc.gov/handwashing/when-how-handwashing.html#:%7E:text=Follow%20Five%20Steps%20to%20Wash%20Your%20Hands%20the%20Right%20Way&amp;text=Wet%20your%20hands%20with%20clean,for%20at%20least%2020%20seconds.">hand hygiene</a> to reduce the risk of rare and common infections. That means washing hands thoroughly and often, using soap, scrubbing for at least 20 seconds, rinsing and drying well. Clip and clean under fingernails regularly</p> <p><strong>4.</strong> to avoid soil-borne parasites wear shoes outside, especially in rural and remote regions, wash shoes and leave them outside.<!-- Below is The Conversation's page counter tag.

5 ways to protect your voice while barracking for the Matildas – and how to treat a hoarse voice after

<p><a href="https://theconversation.com/profiles/amy-hume-1393423">Amy Hume</a>, <em><a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>“It was definitely loud,” said Matildas player Caitlin Foord last week after the team played Denmark in Sydney, <a href="https://sport.optus.com.au/news/womens-world-cup-2023/os61164/matildas-beat-denmark-wwc-caitlin-foord-wish-loud-crowd-sydney">adding "</a>I loved it. We definitely hear it, we feel it and the louder the crowd I feel the better we are."</p> <p>Now fans are set to get even louder, whether watching at home or in a stadium, as the Australian team prepare to face England in their first-ever World Cup semi final.</p> <p>While the Matildas are warming up their limbs and muscles pre-match, spectators need to warm up our vocal folds. With a barracking job to do, we need to be match-fit. Here’s why.</p> <h2>Why do we need to warm up at all?</h2> <p>A sudden night of cheering can lead to vocal strain. The short-term risk is that you have a hoarse voice for a couple of days. Repeated vocal abuse can lead to <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/voice-disorders">permanent damage</a> that may require therapy or surgery.</p> <p>But with some good habits and preparation, you’ll be able to get loud safely. Here are five ways to build vocal stamina for tonight.</p> <h2>1. Get your body ready</h2> <p>The amount of volume you can have in your voice all begins with your body. If you are feeling tight, especially around the neck and shoulders, the muscles around the vocal folds may <a href="https://britishvoiceassociation.org.uk/voicecare_muscle-tension-dysphonia.htm">overcompensate</a>, giving you a tired or strained feeling. Before the match, take a moment to stretch your neck and shoulders for a more open and relaxed throat, ready to roar.</p> <p>And just as the Matilda’s will aim to stay well hydrated, you should too to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2925668/">protect your voice</a>. The vocal structures consist of soft tissues that vibrate better when wet.</p> <h2>2. Yawn – even though you’re excited</h2> <p>Yawning stretches your soft palate (the fleshy back portion of the roof of the mouth) and its flexibility is essential for safe screaming. A vocal technique called <a href="https://pubmed.ncbi.nlm.nih.gov/8353622/">yawn-sigh</a> can also help stretch and warm up the structures like the tongue and pharynx (the passage at the top back of the throat) that are important for voice.</p> <p>Try yawning “horizontally” – smiling widely as you yawn. Then try yawning in the usual “vertical” way. When yawning horizontally, you should feel a different stretch in the back of your mouth and throat that targets your soft palate.</p> <figure><iframe src="https://www.youtube.com/embed/aFxKt1sexVc?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">‘Yawn a lot,’ says actor Morgan Freeman. ‘It relaxes your throat muscles, it relaxes your vocal chords.’</span></figcaption></figure> <h2>3. Breathe</h2> <p>If the semi final is anything like the <a href="https://www.abc.net.au/news/2023-08-13/matildas-world-cup-win-over-france-game-stopped-nation/102723254">quarter final against France</a>, it may be hard to remember to breathe. But breath gives your voice <a href="https://voicefoundation.org/health-science/voice-disorders/anatomy-physiology-of-voice-production/breakdowns-result-voice-disorders/#:%7E:text=If%20the%20airflow%20source%20is,for%20long%20periods%20of%20time.">power</a>.</p> <p>If you roar and cheer without a decent in-breath, the muscles of your throat will tense and strain to try to make the sound louder. It’s not efficient and will tire you out quickly. So every time you go to cheer, allow a big breath in first.</p> <h2>4. Work out your vocal folds</h2> <p>Your voice is like a muscle – actually a <a href="https://www.ncbi.nlm.nih.gov/books/NBK535342/">complex arrangement</a> of cartilage, muscle, ligaments and soft layers. If you stretch it before a workout, it will not only make the exercise easier but also aid recovery time.</p> <p>Your vocal folds are small bands of muscle in the larynx, and you can think of them like elastic. If unused, they can lose stretch and have less vibration capacity to produce sound.</p> <p>Simple exercises like humming and lip trilling can help keep the elasticity of your vocal folds. Start with <a href="https://www.tandfonline.com/doi/abs/10.1179/136132802805576436?journalCode=yslh19">humming</a> at a comfortable pitch and glide up and down your range.</p> <figure><iframe src="https://www.youtube.com/embed/Ddal_OAzkLQ?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The vocal folds in action.</span></figcaption></figure> <h2>5. Put your whole self into it</h2> <p>Your <a href="https://www.frontiersin.org/articles/10.3389/fnins.2016.00506/full">voice, body and emotions</a> are constantly taking cues from one another. If you allow your body to be expressive, your voice will follow. Let your fandom take over your whole body and come into your face too – gestures and facial expressions change the sound of your voice and can bring enormous energy to your roars.</p> <p>Fully commit and trust your body and voice. When we are completely connected to communication, huge breaths can fly in, sound travels up through the vocal folds and rings through the body, giving your voice enormous carrying power.</p> <p>If you try to make your voice low pitched when it wants to come out high, or you hold back from being loud when your voice wants to be heard, tension can come into your throat and lead to strain.</p> <h2>How to treat your voice after the match</h2> <p>You got excited. You overdid the shouting. Understandable! After a full match, you may feel some level of <a href="https://pubmed.ncbi.nlm.nih.gov/20840041/#:%7E:text=Vocal%20fatigue%20is%20defined%20by,component%20of%20other%20voice%20disorders.">vocal fatigue</a>. If your voice sounds rough, hoarse or scratchy with unpredictable pitch, you might have what speech pathologists and ear, nose and throat (ENT) specialists call <a href="https://www.ncbi.nlm.nih.gov/books/NBK565881/">dysphonia</a>.</p> <p>As the Matildas jump in an ice bath, it’s your time to give your voice some TLC.</p> <p>Stretching, yawning, deep breathing and gentle <a href="https://www.ncbi.nlm.nih.gov/books/NBK534632/">voice exercises</a> like humming and trills work for recovery as well as warming up. An exercise I use with actors after a show is gentle whimpering sounds (like a puppy) to soothe vocal folds. Although it’s not widely researched, actors love it.</p> <p>Again, <a href="https://www.nidcd.nih.gov/health/taking-care-your-voice">hydration</a> is important for vocal hygiene, so drink up or <a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199716304805">try a humidifier</a>. Special techniques like <a href="https://pubmed.ncbi.nlm.nih.gov/30408272/">singing through a straw</a> into a half-glass of water can help. Avoid whispering, which can <a href="https://pubmed.ncbi.nlm.nih.gov/16503476/">produce more strain</a> than talking naturally. <a href="https://www.enthealth.org/be_ent_smart/how-to-prevent-hoarseness-dysphonia/">Avoid</a> smoking or smoky spaces, excessive throat clearing and alcohol or caffeine that can dry out the throat and thicken mucus.</p> <p>With all the love behind the Matildas, they’ve got a chance of reaching the World Cup final. Even more reason to look after your voice and maintain match fitness. Go Matildas!<!-- Below is The Conversation's page counter tag.

6 reasons cats need some indoor rules

<p><strong>Kitty cat behaviours</strong></p> <p>Cat behaviour is both wildly entertaining and, at times, perplexing. Even the most in-tune owner has to wonder why cats knock things over, why cats love boxes or why cats meow at people but chirp at birds and squirrels. What cat lovers do know is that kitties crave spaces with bird’s-eye views to observe their world – you know, like kitchen counters.</p> <p>But if you’re trying to keep foods toxic to cats away from your little lion, or you’re just fed up with constantly cleaning your kitchen to get rid of cat hair and little pieces of cat litter, here’s how to keep cats off counters for good.</p> <p><strong>Why do cats like to climb on counters?</strong></p> <p>It’s a curious conundrum: Why do cats hate water yet jump on kitchen counters to play with a dripping faucet? An even more puzzling question: Why do cats like to hang out on our countertops in the first place?</p> <p>“Cats are both predators and prey, so being able to survey their territory from above keeps them safe from predators and allows them to spot prey to catch,” says Samantha Bell, a cat expert with Best Friends Animal Society. That’s understandable, but domestic cats don’t have to catch their food, and they certainly don’t have to worry about predators, so why do they like to be up on the counter so much?</p> <p>“Counters are so attractive to cats because they’re up high, sturdy, right in the middle of the action and full of food,” Bell says. (Which may be one reason your cat licks you when you’re making a meal – it smells food on your hands.)</p> <p>Your actions can reinforce this counter-jumping habit. If you pet and talk to your cat while it’s on the counter, it’ll quickly learn that this is a place where it can get attention, says Dr Ragen T.S. McGowan, an animal behaviour scientist with Purina. “Many cats will jump up on the counter just to be close to human family members,” she says.</p> <p><strong>Can you train a cat to not be on your counters?</strong></p> <p>Absolutely, but there are two vital cat facts you should know when it comes to how to keep cats off counters, Bell says. To start, you can’t extinguish instinctive behaviours, like climbing high to be near the action.</p> <p>Furthermore – and this is a biggie – punishment doesn’t work. In fact, it can even cause cat anxiety and destructive behaviours. Here are a few ways you can teach your kitty to stay off your counters for good.</p> <p><strong>Remove the reward</strong></p> <p>You can train a cat to do a lot of things, and yes, staying off the counters is one of them. Here’s a critical question to ask when figuring out how to keep cats off counters: What is your cat’s reward for counter surfing?</p> <p>We know our feline friends hop on countertops to get food and attention and to socialise with humans. Maybe your cat is motivated by one or all of those factors. Or maybe it loves watching birds out the kitchen window. Whatever the case may be, you can train a cat to stay off the counters by removing rewards and positive reinforcement, McGowan says.</p> <p>Let’s say your cat is curious about the water dripping from the sink tap, likes to watch birds out the window or wants to nibble on food left on the counter. “Remove the reward by drawing the shades, fixing the tap or removing food from the countertops when possible,” says McGowan.</p> <p>And don’t fall into the trap of rewarding this bad behaviour. “For many cats, even the act of picking them up off the counter is rewarding and thus reinforces the behaviour,” says McGowan. Think about it: Your cat may rub against you while it’s on the counter and purr when you pick it up – both ways cats show affection. When you pick it up, you’re giving affection and attention and essentially telling your cat that climbing on the counter is a good way to get cuddles.</p> <p><strong>Redirect the cat's attention</strong></p> <p>Your cat may be climbing to get your attention, but before you give in and pet it, redirect its attention from the counter. “If their motivation is touch [being picked up or petted], then tossing a treat or toy and petting them only after they are on the floor can help to redirect them,” says McGowan.</p> <p>As tempting as it is, don’t pet your cat when it’s on the counter, as this can inadvertently reward the behaviour. Instead, call your cat to another part of the kitchen before giving it a treat or toy. Otherwise, McGowan says, it might learn a new trick: “If I get on the counter, Mum or Dad will throw a treat.”</p> <p>Consistently provide the rewards when your cat is not on the counter, and it’ll learn that being in other places gets it a reward, according to McGowan.</p> <p><strong>Teach it that counters are boring</strong></p> <p>It’s the old switcheroo! With this technique, you’re training your cat to choose a new place to hang out, one that’s still at the height level it prefers. Place a tall chair or stool near the counter, then reward your four-legged friend each time it sits there.</p> <p>We know what you’re thinking: This sounds counterintuitive. Won’t the cat use the barstool to jump onto the counter? “Yes, but they were getting on the counter anyway. The point is that you only reward them when they’re on the stool,” says Bell. “When you catch your cat on the stool, reward them with something of great value to them.”</p> <p>Don’t place the cat on the stool yourself. But you can lure it up to the stool by putting treats on it. If your cat jumps up on the counter during this training phase, play it cool. Remember, some cats have learned that being picked up from the counter means they’re going to get affection and cuddles. “Don’t say anything. Don’t look at them. Just quickly and gently set them on the ground,” says Bell.</p> <p>The goal is to show your cat there is nothing exciting about being on the counter. It only gets rewarded when it’s on the stool or high chair. “They learn quickly which location gets rewarded,” Bell adds.</p> <p>Granted, training takes some time and patience, but once cats realise rewards come when they’re on the barstool, you’ll have cat-free counters, Bell says. Once your pet nails the behaviour, you can stop giving it treats every time it gets on the stool. “That could cause a slot machine behaviour effect of ‘I’ll keep trying until I win,’” she says.</p> <p><strong>Set up cat-climbing alternatives</strong></p> <p>You’ve probably heard the saying “location, location, location.” It tops the wish list of most hopeful home buyers. For cats, that location is vertical. “Cats are drawn to high places to perch and survey the world, as they feel more secure from a high vantage point,” McGowan says. You can satisfy their desire for elevated living without sacrificing your clean countertops.</p> <p>For a simple and free option, Bell suggests putting a nightstand close to a dresser so your cat can easily jump to the dresser. Make it extra comfy and put a cosy blanket or cat bed on top of the dresser.</p> <p>You can give your cat a bird’s-eye view with products that put it at eye level with the action – wall shelves and bridges, window seats perfect for cat naps and cat trees with built-in scratching posts, toys and plush hideaways.

Facebook Messenger scams are on the rise – here’s how to protect yourself

<p><strong>Facebook Messenger scams prey on our vulnerabilities</strong></p> <p>Scams through Facebook’s Messenger platform are being reported at higher rates than ever before, according to AARP, citing its own data as well as that of the government. Since Facebook’s early days, cybercriminals have been mining Facebook’s direct-messaging capabilities to scam unsuspecting victims out of money. One of the earliest Facebook Messenger scams involved a message, purportedly from a friend, claiming they were stuck in a foreign country and in desperate need of immediate financial assistance to get out. It wasn’t really the friend, however, but rather a scammer who had hacked into the friend’s account. </p> <p>Imposter scams such as “the friend in a foreign country” have evolved and proliferated over the years. The common thread is the scammer either creates an account impersonating an actual Facebook account or hacks into an existing Facebook account. In either case, the scammer then uses the fake/hacked account to send private messages to the account holder’s friends that elicit either money or personal information. The messages vary, but all are designed to prey on our human vulnerabilities, including:</p> <ul> <li>the desire to be a “hero”</li> <li>the desire to appear “generous”</li> <li>the desire to win “free money”</li> <li>the desire to be loved and admired</li> <li>the desire to avoid shame or punishment</li> </ul> <p>If a scammer tries to message you, report them, Facebook advises, but that begs the larger question of how does one recognise a Facebook Messenger scam?</p> <p><strong>Current Messenger Facebook scams</strong></p> <p>According to Facebook and our cybersecurity experts, here are the most common Facebook Messenger scams today:</p> <p><span style="text-decoration: underline;"><em>Romance scams</em></span>. Preying on our desire to be loved and admired, romance scammers appear as attractive strangers with sad stories and a desire to love and be loved. The most effective romance scammers will friend a number of mutual friends before reaching out to any of them, in an attempt to make themselves seem less like strangers and more like people in the same social network. Many use photos they’ve stolen off the Internet and many pose as members of the military or as doctors, in an attempt to inspire trust, admiration, and even authority. What they all have in common is they can’t meet you just yet because they’re somewhere far away, and although it may take a bit of time, even as much as several weeks, they will eventually ask you to send money so that they can come to see you.</p> <p><span style="text-decoration: underline;"><em>Lottery scams</em></span>. Preying on our desire for “free money,” lottery scammers appear as friends or organisations who are thrilled to tell you you’ve won money in some lottery or contest. The common thread? It’s a contest you have no recollection of having entered and to get the prize, you’ll have to either pay a fee or “refundable” advance or provide personal information.</p> <p><span style="text-decoration: underline;"><em>Inheritance scams</em></span>. Also preying on our desire for free money, inheritance scammers claim to be lawyers or others who represent someone who has died and supposedly left you their estate or some portion of it – but first, you’ll have to fork over some money or personal information.</p> <p><span style="text-decoration: underline;"><em>Loan scams</em></span>. Another variation on the “free money” theme is the loan scam, whereby the scammer promises low-interest loans with no money down – except for a “refundable” application fee. Facebook points out that loan scammers may send messages via Messenger and also leave posts and comments on Pages and in Groups to legitimise themselves. However, legitimate lenders wouldn’t offer loans via Facebook Messenger, nor would they ask you for money to proceed with a loan application.</p> <p><span style="text-decoration: underline;"><em>Donation scams</em></span>. Facebook specifically warns users to watch out for “famous people” or people claiming to represent a charity hitting them up for a donation. Donation scams, which are easy money for a scammer because they are a direct request for payment, prey on our desire to be perceived, or to perceive ourselves, as generous.</p> <p><span style="text-decoration: underline;"><em>“Hey, is this you?” scams</em></span>. Consumer Affairs warns of this “phishing scam” that uses the threat of shame to goad you into giving up personal information. The scammer hacks into one of your Facebook friend’s Messenger accounts and sends you a video, asking if it’s really you in the video, and implying there’s something in the video that could embarrass you. If you ever get a message like this, Consumer Affairs urges you to ignore and delete it to avoid giving away personal information or introducing a virus onto your computer.</p> <p><strong>Red flags to watch out for</strong></p> <p>Unfortunately, Facebook Messenger scams evolve rapidly (as soon as we suss them out, there are several more to replace them). So, it’s a good idea to be aware of these warning signs that we culled from our experts:</p> <p><span style="text-decoration: underline;"><em>Someone is asking you for money</em></span>. While Facebook warns specifically against strangers asking for money, Rachel Wilson, investigative coordinator for The Smith Investigation Agency, points out to Reader’s Digest that any time anyone asks you for money over Messenger, it’s immediately suspect. “If friends or family ask you to help them in an emergency, always call to speak with them personally to confirm that the message originated with them.”</p> <p><span style="text-decoration: underline;"><em>Someone is getting a little too personal</em></span>. When someone sends you a message requesting personal information, especially financial information, it should be considered suspicious, advises Sean Messier, credit industry analyst for Credit Card Insider. Messier suggests not revealing any such information until you’re certain the message-sender is who they claim to be, but it’s probably also a good idea to never reveal any such information over Messenger at all.</p> <p><span style="text-decoration: underline;"><em>Someone is offering something for free</em></span>. You know how they say there’s no such thing as a free lunch? Well, there’s no such thing as free money on Facebook, points out Robert Siciliano, security expert. This is true for any kind of “free money” Messenger message, including those involving lotteries, loans, contest winnings, inheritances, lost bank accounts, and reimbursements of money owed.</p> <p><span style="text-decoration: underline;"><em>Someone who wants to take the conversation off Facebook (to text or email, etc)</em></span>. Facebook warns against taking conversations off Facebook unless you’re absolutely certain, beyond a shadow of a doubt, the message sender is who they say they are.</p> <p><span style="text-decoration: underline;"><em>Messages that seem out of character for the sender</em></span>. If a message seems “out of the norm” for the sender, trust your instincts and ignore it. This is doubly true if the message includes an attachment. Be very wary of opening attachments in general, and particularly if something seems “off” about the message or the sender.</p> <p><span style="text-decoration: underline;"><em>Messages rife with spelling and grammatical errors</em></span>. Facebook points out that when a message is filled with typos and grammatical errors, you should have your guard up. A single typo is one thing, but things like the misspelling of names and places are a big red flag.</p> <p><span style="text-decoration: underline;"><em>Messages from new accounts with few friends</em></span>. Roger Thompson, CEO of Thompson Cybersecurity Labs, points out that new accounts with few friends should always be considered suspicious until confirmed otherwise. Friend requests from such accounts and from duplicate friend accounts should be considered suspect as well.</p> <p>To avoid getting hacked (and used by a cybercriminal in an imposter scam), Wilson recommends updating your social media passwords regularly and always use two-factor authentication. She also notes that with Facebook use increasing among seniors, it would be a good deed to speak to older family members about Messenger scams and how to avoid them.</p> <p><em>Image credits: Getty Images </em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/true-stories-lifestyle/science-technology/facebook-messenger-scams-are-on-the-rise-heres-how-to-protect-yourself" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>
