Loch Ness monster back in headlines after "most exciting" photo in decades

<p>A recent potential Loch Ness monster sighting has generated immense excitement among monster enthusiasts, who claim these photographs are the most captivating seen in decades.</p> <p>The incident unfolded when Chie Kelly, 51, inadvertently captured images of an unidentified, sizeable creature gliding across the surface of Loch Ness five years ago in August.</p> <p>At the time, she hesitated to release the images, fearing public ridicule. However, her decision changed after the largest 'Nessie' search in over half a century took place last month – called The Quest Weekend.</p> <p>Kelly, accompanied by her family, was enjoying a meal at an inn nestled on the shores of the Scottish loch when she began snapping photos.</p> <p>According to the <a href="https://lochness.com/findings-revealed-from-the-quest-weekend/" target="_blank" rel="noopener">Lochness.com website</a>, Chie Kelly "had lunch in the Dores Inn and then started walking around. I was just taking pictures with my Canon camera of Scott and our daughter Alisa, who was then five, when about 200 metres from the shore, moving right to left at a steady speed was this creature.</p> <p>"It was spinning and rolling at times. We never saw a head or neck. After a couple of minutes, it just disappeared and we never saw it again.</p> <p>"At first I wondered if it was an otter or a pair of otters or a seal, but we never saw a head and it never came up again for air.</p> <p>"It was making this strange movement on the surface. We did not hear any sound. There were these strange shapes below the surface. I could not make out any colours – the water was dark. I could not accurately assess its length, but the two parts that were visible were less than two metres long together.</p> <p>"I don’t know what it was, but it was definitely a creature – an animal. At the time I did not want to face public ridicule by making the photographs public. But I met Steve Feltham at the weekend and showed him the images, and he said immediately that they were ‘very interesting’.”</p> <p>Feltham has dedicated more than 30 years to the search for Nessie since abandoning his job and selling his house in 1991. After looking at the images, he said, “These are the most exciting surface pictures I have seen. They are exactly the type of pictures I have been wanting to take for three decades.</p> <p>"It is rare to see something so clear on the surface. They are vindication for all the people who believe there is something unexplained in Loch Ness. They are remarkable. I have studied them and still do not know what it is. I persuaded them that these pictures were so important they should make them public. They warrant further investigation. It is not driftwood – it is a moving creature and totally unexplained.”</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CrRewR8txip/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/CrRewR8txip/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by Chie Tchié Kelly-Kano (@kelly.chie)</a></p> </div> </blockquote> <p>Reports of the Loch Ness monster have spanned ancient history, with stories dating back to an Irish missionary allegedly rescuing a swimmer from a creature in the loch during the 7th century.</p> <p>The completion of a road adjacent to the loch in 1933 led to a surge in monster sightings.

Got no COVID-19 symptoms? A gene mutation might be the reason

<div class="copy"> <p>A global study has unearthed a possible genetic reason why some people infected with the virus that causes COVID-19 show no symptoms.</p> <p>Human leukocyte antigens – or HLAs – are important genes that support immune function in the human body, particularly in identifying viral pathogens.</p> <p>And a particular variation in the HLA-B complex has been found to at least double the likelihood that a person infected with SARS-CoV-2 will be asymptomatic.</p> <p>For people who inherit a copy of the HLA-B15 variant from one parent, there was a 2.4 times greater chance of avoiding symptoms. Homozygous carriers — born with copies of the variant from each parent — were 8.5 times more likely to avoid symptoms.</p> <p>It’s a somewhat common variant among certain ethnicities – about 1 in 10 people with European ancestry are potential carriers – but having the gene is not a guaranteed protector against coronavirus symptoms.</p> <p>The findings, <a href="https://doi.org/10.1038/s41586-023-06331-x" target="_blank" rel="noreferrer noopener" data-type="URL" data-id="https://doi.org/10.1038/s41586-023-06331-x">published</a> in <em>Nature</em>, have emerged from a joint study between researchers at the University of California San Fransisco and Australian institutions including Latrobe University, Monash University and the QIMR Berghofer Centre.</p> <p>The research came about almost by accident.</p> <div class="in-content-area content-third content-right"> </div> <p>Co-lead authors Professor Stephanie Gras from Latrobe and Jill Hollenbach from UCSF first met at a research conference in May 2022 and pooled their resources to track the association of possible gene variations with COVID-19 symptoms.</p> <p>Their teams narrowed a group of 30,000 people with high-quality HLA data to a cohort of about 1,500 unvaccinated people who tested positive for the virus. They then focussed on five locations of interest in the HLA genes while monitoring the emergence of symptoms to determine which variants, if any, might have a greater linkage to being COVID asymptomatic.</p> <p>“The [SARS-CoV-2] virus gets inside cells and ‘presents’ some small part of the virus on the surface via the HLA molecule,” Gras explains.</p> <p>“Those act as a red flag for T cells. The cell sends the signal to the T cell that it has been infected with the virus, and the T cells get activated and kill that [infected] cell.</p> <p>“HLA-B15 can actually present a small part of the spike protein that is very similar between SARS-CoV-2 and seasonal coronaviruses… [that] circulate every year in the population and give us the common cold during winter most of the time. They share some similarities.”</p> <p>The understanding provides a possible application for future treatments. Now an association between the variant and asymptomatic cases has been identified, the Gras and Hollenbach teams have begun to study the interaction between HLA-B15 and the SARS-CoV-2 spike protein at the atomic level.</p> <p>That research is already underway, including at the Australian Synchrotron at the Australian Nuclear Science and Technology Organisation.</p> <p>“We’re doing atomic-level models of proteins to understand the interaction,” Gras says.</p> <p>“We want to compare the T cells within people who are asymptomatic with HLA-B15 and people who are not asymptomatic with HLA-B15. Actually, HLA-B15 is not a magic bullet, you can have it and still have severe COVID.”</p> <p><em>Image credits: Getty Images</em></p> </div> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/health/covid/got-no-covid-19-symptoms-a-gene-mutation-might-be-the-reason/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/matthew-agius">Matthew Ward Agius</a>. </em></p> </div>

KISS concert halted as Gene Simmons falls ill on stage

<p>KISS singer Gene Simmons gave fans - and bandmates - a fright when dehydration got the better of him live on stage, and the group were forced to bring their entire concert to a halt. </p> <p>In a video from the event, KISS’ Paul Stanley can be seen addressing the crowd, telling them that “we’re gonna have to stop to take care of him. Because we love him, right?”</p> <p>He goes on to call for a cheer for Simmons, with the 73-year-old catching his breath on a chair on stage - the same chair that he remained in for the rest of the show, after a five minute break to assure he was well enough to continue.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="pt">Gene Simmons, baixista e vocalista do Kiss, passa mal e show é brevemente interrompido na Arena da Amazônia. <a href="https://t.co/nphJEj1PQo">pic.twitter.com/nphJEj1PQo</a></p> <p>— A Crítica (@ACritica) <a href="https://twitter.com/ACritica/status/1646372105523478529?ref_src=twsrc%5Etfw">April 13, 2023</a></p></blockquote> <p>And while fans were concerned for the singer, he later took to social media to assure them that he was “fine” and looking forward to the band’s next stadium performance. </p> <p>“I’m fine. Yesterday at Manaus Stadium in Brazil, [I] experienced weakness because of dehydration,” he explained. “We stopped for about five minutes, I drank some water, and then all was well. Nothing serious.”</p> <p>“Brazil is hotter than hell!!” one fan responded, “so glad you're okay and I can't wait to see you in São Paulo! Take care, god of thunder!!”</p> <p>“Even the God of Thunder needs hydration,” another agreed. “Good to hear you're doing well.”</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Hey everybody, thanks for the good wishes.

Humidity and temperature were sky high. I was dehydrated and was forced to sit for a song,” he said. “We got back on stage in 5 minutes &amp; finished the show.”</p> <p>It was enough for his fans, who were quick to share their delight that their star was okay, as well as voicing their excitement for upcoming shows - with a good portion of requests for the singer to take care of himself, and avoid a repeat performance. </p> <p>“Happy to hear you're doing better,” one wrote. “Even more happy it wasn’t anything serious.Ya'll take care.”</p> <p>“Frankly, I don’t know [how] you do it every night.

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

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

Severe COVID-19 linked to signs of ageing in the brain

<p dir="ltr">COVID-19 infection has been associated with the same molecular changes seen in ageing brains, including higher levels of activity from genes associated with the ageing process.</p> <p dir="ltr">As we age, our brains shrink - with a five percent decline in weight per decade after the age of 40 - while our memory and levels of neurotransmitters like serotonin and dopamine decline.</p> <p dir="ltr">With previous research finding that people who are infected with Covid can experience neurological conditions after they recover, as well as declines in cognitive performance that mimic accelerated ageing, a team of researchers from Harvard Medical School examined the brain tissue of 54 deceased people, including 21 who had severe Covid infections.</p> <p dir="ltr">They found that changes in how genes were expressed in the brains of Covid-infected people were similar to what is seen in older brains.</p> <p dir="ltr">Using a particular kind of analysis called whole-transcriptome sequencing, the team were able to investigate which genes were being switched on and off in a person at the time of their death, comparing brain samples from people infected with Covid and those who hadn’t been infected (from before the pandemic).</p> <p dir="ltr">In comparison to the uninfected group, the Covid group showed higher levels of activity for genes associated with immunity. Meanwhile, genes linked to cognition, memory and the activity of synapses, which are essential for helping impulses travel through the nervous system, had lower levels of expression.</p> <p dir="ltr">"We also observed significant associations of cellular response to DNA damage, mitochondrial function, regulation of response to stress and oxidative stress, vesicular transport, calcium homeostasis, and insulin signalling/secretion pathways previously associated with ageing processes and brain ageing," they wrote.</p> <p dir="ltr">"Altogether, our analyses suggest that many biological pathways that change with natural ageing in the brain also change in severe COVID-19."</p> <p dir="ltr">Also investigating the trigger of these changes, they found increased levels of activity in several inflammatory pathways associated with ageing in the brain, and that specific immune cells influence the expression of several of these genes.</p> <p dir="ltr">This supports the hypothesis that the neurological symptoms that can accompany Covid are caused by inflammation triggered by the virus.</p> <p dir="ltr">But they also explored the other hypothesis, that the neurological symptoms are caused by the virus infiltrating and infecting the brain - specifically the frontal cortex - by looking to see whether there was evidence of Covid RNA (which contains the virus’ genetic material it needs to replicate).</p> <p dir="ltr">“In agreement with previous studies, SARS-CoV-2 viral RNA was not detected in samples from individuals with COVID-19, suggesting that the observed gene expression changes are unlikely due to the effects of the viral RNA in the frontal cortex,” they wrote.</p> <p dir="ltr">With these findings, the researchers concluded that managing Covid-induced inflammation could protect against the development of the neurological symptoms associated with Covid.</p> <p dir="ltr">They also argue that following up with patients recovering from Covid could be beneficial in reducing the risk or delaying the neurological symptoms and cognitive decline.</p> <p dir="ltr">Speaking to <em>Nature</em>, neuropathologist Marianna Bugiani, who wasn’t involved in the study, said that it’s still difficult to know whether these changes to gene expression are permanent or whether they are also seen in people experiencing mild bouts of Covid.</p> <p dir="ltr">“It opens a plethora of questions that are important, not only for understanding the disease, but to prepare society for what the consequences of the pandemic might be,” she said.</p> <p><span id="docs-internal-guid-df4fb67d-7fff-854d-6942-559608bd9c1f">“And these consequences might not be clear for years.”<br /></span></p> <p>The researchers published their findings in the journal <a href="https://doi.org/10.1038/s43587-022-00321-w" target="_blank" rel="noopener"><em>Nature Aging</em></a>.</p> <p><em>Image: Getty Images</em></p>

Chris Hemsworth’s Alzheimer’s gene doesn’t guarantee he’ll develop dementia

<p>Chris Hemsworth, famous for his role as the god Thor in Marvel Cinematic Universe movies, has announced he will be <a href="https://www.theguardian.com/film/2022/nov/21/chris-hemsworth-to-take-time-off-from-acting-after-discovering-alzheimers-risk" target="_blank" rel="noopener">taking a break</a> from acting after being told he has two copies of the <a href="https://www.nia.nih.gov/news/study-reveals-how-apoe4-gene-may-increase-risk-dementia" target="_blank" rel="noopener">APOE4 gene</a>, increasing his risk of Alzheimer’s.</p> <p>Having one copy of the <a href="https://www.science.org/doi/abs/10.1126/science.8346443" target="_blank" rel="noopener">APOE4 gene</a> increases your risk for Alzheimer’s 2-3 times. Two copies increases your risk 10-15 times.</p> <p>But the key here is “risk”. Having one or more copies of the gene doesn’t guarantee Chris or anyone else in a similar situation will go on to develop Alzheimer’s, the most common form of dementia.</p> <p><strong>Sharing the news</strong></p> <p>Hemsworth’s willingness to share his concerns about developing Alzheimer’s with millions should be applauded. It’s a reminder to all of us to keep an eye on our health and reduce our risk of future illness.</p> <p>Alzheimer’s, and dementia more broadly, is <a href="https://www.dementiastatistics.org/statistics/global-prevalence/" target="_blank" rel="noopener">set to challenge</a> health-care systems worldwide.</p> <p>In Australia alone there are <a href="https://www.dementia.org.au/statistics" target="_blank" rel="noopener">up to</a> 500,000 people with dementia, supported by almost 1.6 million carers. By 2036, about <a href="https://www.dementia.org.au/sites/default/files/NATIONAL/documents/The-economic-cost-of-dementia-in-Australia-2016-to-2056.pdf" target="_blank" rel="noopener">450 people</a> are predicted to be diagnosed daily. So understanding how APOE4 alters the risk for the major cause of dementia may be pivotal in preventing cases.</p> <p>But not all people with the APOE4 gene go on to develop Alzheimer’s. This means that there may be a combination of environmental factors interplaying with the gene that lead some people to develop Alzheimer’s, while others do not.</p> <p><strong>What’s APOE4 got to do with Alzheimer’s?</strong></p> <p>Most Australians have APOE3 or APOE2 genes. In Caucasians it’s only <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5531868/" target="_blank" rel="noopener">about 15%</a>, like Hemsworth, who have inherited an APOE4 gene.</p> <p>The APOE gene types are best known for their role in modulating the metabolism of lipids (fats), such as cholesterol and triglycerides.</p> <p>They code for synthesis of different versions of the protein APOE, with subtle differences in structure. The APOE proteins become an integral part of lipoproteins in the blood. These are the fat-carrying particles your GP measures to consider your risk of heart disease.</p> <p>APOE proteins have a similar function in the brain, to modulate lipid levels. But in the context of Alzheimer’s, researchers study it for its effect on the integrity of brain cells.</p> <p>Accumulating evidence <a href="https://www.sciencedirect.com/science/article/pii/S0197458022000550" target="_blank" rel="noopener">suggests</a> APOE4, is associated with brain inflammation and cellular damage.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">APOE4 is the strongest genetic risk factor for Alzheimer’s disease. A study in <a href="https://twitter.com/Nature?ref_src=twsrc%5Etfw">@Nature</a> establishes a functional link between APOE4, cholesterol, myelination and memory, offering therapeutic opportunities for Alzheimer’s disease. <a href="https://t.co/bNsmDVPfFW">https://t.co/bNsmDVPfFW</a> <a href="https://t.co/58odE1JASl">pic.twitter.com/58odE1JASl</a></p> <p>— Nature Portfolio (@NaturePortfolio) <a href="https://twitter.com/NaturePortfolio/status/1594762841487249410?ref_src=twsrc%5Etfw">November 21, 2022</a></p></blockquote> <p><strong>Can we prevent Alzheimer’s?</strong></p> <p><strong>1. Look after your capillaries</strong></p> <p>Damaged and leaky blood vessels (capillaries) in the brain lead to inflammation, the death of brain cells and cognitive impairment. In fact, in Alzheimer’s, damaged capillaries are the earliest sign of the type of brain damage that causes disease.</p> <p>The protein encoded by the APOE4 gene may be less able to support healthy capillaries in the brain. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0163782709000563" target="_blank" rel="noopener">We suggested</a> APOE4 increases the abundance of specific complexes of lipoproteins and proteins in blood that silently damage brain capillaries, causing them to leak.</p> <p>We also see more brain capillary leakage in mice fed Western-style diets richer in saturated fats.</p> <p>The relationship between how the APOE proteins mediate lipid metabolism and capillary health in humans is poorly understood.</p> <p>But we have 60 years of research knowledge to say with confidence that eating foods good for the heart should also be good for the brain. This is particularly relevant for people with the APOE4 gene.</p> <p>So if you have the APOE4 gene and want to minimise your risk of Alzheimer’s, a healthy diet is a good place to start.</p> <figure class="align-center zoomable"><em><a href="https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=3 2262w" alt="Capillaries" /></a></em><figcaption><em><span class="caption">Looking after your capillaries with a healthy diet is a good place to start.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-illustration/system-many-small-capillaries-branch-out-1745173364" target="_blank" rel="noopener">Shutterstock</a></span></em></figcaption></figure> <p><strong>2.

This new tech could spell end for mouse plagues

<p dir="ltr">Invasive mice populations could be a thing of the past, thanks to a new genetic tool developed by a team of Australian scientists.</p> <p dir="ltr">Researchers at the University of Adelaide have developed t-CRISPR, which uses gene editing technology to alter the fertility gene in laboratory mice to make females infertile.</p> <p dir="ltr">“This is the first time that a new genetic tool has been identified to suppress invasive mouse populations by inducing female infertility,” said lead researcher Professor Paul Thomas.</p> <p dir="ltr">“The t-CRISPR approach uses cutting-edge DNA editing technology to make alterations to a female fertility gene. Once the population is saturated with the genetic modification, all the females that are generated will be infertile.</p> <p dir="ltr">“We are also developing new versions of t-CRISPR technology that are designed to target specific pest populations to prevent unwanted spread of the gene drive.”</p> <p dir="ltr">The new tool is based on an existing technology, CRISPR-Cas9 gene editing, which has largely been applied to limiting the spread of malaria by making male mosquitoes infertile.</p> <p dir="ltr"><strong>CRISPR 101</strong></p> <p dir="ltr">Since it was unveiled in 2012, the CRISPR method has been used to edit pieces of DNA inside the cells of organisms, primarily insects.</p> <p dir="ltr">“Up until now, this technology has been aimed at insects to try and limit the spread of malaria, which causes up to 500,000 deaths worldwide per year,” Luke Gierus, a post-graduate student and the paper’s co-first author, said.</p> <p dir="ltr">The technology relies on the Cas9 protein found in bacteria, which scientists can program to find and bind to almost any 20-letter sequence of DNA in a gene with the help of a piece of RNA that matches the target DNA sequence.</p> <p dir="ltr">When it finds the target, standard CRISPR cuts the DNA, and the process of repairing the DNA introduces mutations that can disable the gene.</p> <p dir="ltr">Other variations of CRISPR can also replace faulty genes, turn genes on or off, or change one letter of the DNA code to another.</p> <p dir="ltr">In this study, the team simulated what would happen when an edited version of a fertility gene on chromosome 17, which affects the ability of sperm to swim, was introduced to populations of mice. </p> <p dir="ltr">Males who carry one copy of this gene are infertile, while females are still fertile but only have one functioning version of the gene and can pass on either the functioning or non-functioning version to their offspring.</p> <p dir="ltr">In females that had a second edited chromosome that affected their fertility, they found that male offspring would all be infertile, while only 50 percent of female offspring would be fertile.</p> <p dir="ltr">They found that 250 mice with modified genes could eradicate a population of 200,000 mice on an island in around 20 years.</p> <p dir="ltr">“The use of t-CRISPR technology provides a humane approach to controlling invasive mice without the release of toxins into the environment. We are also working on strategies to prevent failed eradication due to the emergence of gene drive resistance in the target population,” Gierus said.</p> <p dir="ltr">While t-CRISPR has been developed to specifically target mice, CSIRO Group Leader for Environmental Mitigation and Resilience Dr Owain Edwards said it could be developed to use on other invasive animals.</p> <p dir="ltr">The researchers, who collaborated with CSIRO, the Centre for Invasive Species Solutions, the Genetic Biocontrol for Invasive Rodents (GBIRd) consortium and the US Department of Agriculture, were supported by both the South Australian and NSW governments.</p> <p dir="ltr">“These promising findings demonstrate how gene drive technology may be a game changer in managing the impacts of mice on our environment, community, and agricultural sector,” South Australian Deputy Premier Dr Susan Close said.</p> <p dir="ltr">“This cutting-edge research also highlights the global leadership of the South Australian research sector, in finding solutions to social, environmental and economic challenges.</p> <p dir="ltr">“The South Australian Government is proud to have supported this proof-of-concept, having granted the University of Adelaide $1 million through the Research and Innovation Fund.”</p> <p dir="ltr">They published their findings in the journal <em><a href="https://doi.org/10.1073/pnas.2213308119" target="_blank" rel="noopener">Proceedings of the National Academy of Sciences</a></em>.</p> <p><span id="docs-internal-guid-bca82366-7fff-dcca-05a4-83502245beac"></span></p> <p dir="ltr"><em>Image: ABC News</em></p>

"Clueless": Meghan Markle told to show some gratitude

<p dir="ltr">American journalist Megyn Kelly has once again called out Meghan Markle for always talking about herself. </p> <p dir="ltr">The Duchess of Sussex came out swinging in her latest podcast titled <em>To ‘B’ or not to ‘B’?</em>, in which she hit back at her nickname, “Duchess Difficult”.</p> <p dir="ltr">She said the nickname was a way of gaslighting women and “is really a codeword for the B-word”.</p> <p dir="ltr">Kelly had enough of the Duchess’ incessant nagging and said there was another word to call her. </p> <p dir="ltr">“I wouldn’t necessarily call her the B-word, but I would definitely call her the C-word: clueless,” she said on the GB News <em>Dan Wootton Tonight</em> program.</p> <p dir="ltr">“She’s utterly clueless and I am so sick of her off-point irrelevant musings about her non-problems.”</p> <p dir="ltr">She went on to reveal that the homicide rates of more than 100,000 homeless people in California, where Meghan lives, “reached an all-time high”. </p> <p dir="ltr">“And we are supposed to give a damn if someone is calling [Meghan] the b-word or difficult?” Kelly continued.</p> <p dir="ltr">“We don’t, she doesn’t get it. No one gives a damn about these non-problems.</p> <p dir="ltr">“She should stop complaining and start showing some gratitude for what appears to be a very beautiful life of which she finds nothing to celebrate.</p> <p dir="ltr">“We don’t care. Shut up! Stop talking about yourself and show some humility and gratitude.”</p> <p dir="ltr">Meghan was given the nickname back in 2018 when she was accused of displaying “dictator” style behaviour towards her staff members - which led to one of them quitting.</p> <p dir="ltr">“My friend said to me, there’s a certain point when you come to terms with the fact that not everyone is going to like you,” Meghan continued.</p> <p dir="ltr">“The goal can’t be for everyone to like you, but the goal can be for them to respect you.”</p> <p dir="ltr"><em>Images: Getty/GB Tonight</em></p>

“We get it!”: Journalist slams Meghan Markle's flaunting of "her husband"

<p dir="ltr">American journalist Megyn Kelly has called out Meghan Markle for constantly referring to Prince Harry as “her husband”, claiming the former royal is doing it for attention.</p> <p dir="ltr">In the latest episode of her podcast, Kelly criticised the Duke and Duchess of Sussex for “ripping on the royals”, to whom she said the couple owed literally “all of their fame and most of their fortune”.</p> <p dir="ltr">She also took great annoyance with Meghan referring to Harry, who she married in 2018, as her husband.</p> <p dir="ltr">“We get it, you bagged the gorilla,” Kelly said.</p> <p dir="ltr">“Congratulations, you got the big bear, [and] you want us all to know.”</p> <p dir="ltr">Her criticism comes after Meghan spoke at length about Harry’s parenting skills in the latest episode of her podcast, <em>Archetypes</em>.</p> <p dir="ltr">“Oh, my husband? Oh, he's great!” the 41-year-old said when asked whether Harry contributed much to parenting duties.</p> <p dir="ltr">She said that Harry would help Archie while she cooks breakfast during their “chaotic” mornings.<br />“I make breakfast for all three of them. It’s very important to me. I love doing it,” Meghan added.</p> <p dir="ltr">Kelly also took aim at Meghan for claiming she had never looked up the royal family prior to her relationship with Harry, calling the duchess a “liar”.</p> <p dir="ltr">The claim in question dates back to Meghan’s interview with Oprah Winfrey, where she said she “never looked up my husband online”.</p> <p dir="ltr">“I just didn't feel the need to because everything that I needed to know, he was sharing with me — or everything we thought I needed to know, he was telling me,” she said at the time.</p> <p dir="ltr">Christopher Anderson, who appeared on the episode of Kelly’s podcast to talk about his new book, The King: The Life of Charles III, said that Meghan was like “every other young woman” and in love with the royals.</p> <p dir="ltr">“She, like every other young woman that age, they were all in love with [the royals]. There are pictures of her at the gates of Buckingham Palace when she was a teenager,” he said.</p> <p dir="ltr">“Let's get real, there's always that eligible bachelor,' Kelly replied.</p> <p dir="ltr">“For my age, it was JFK Jr., for her age it was Prince Harry.</p> <p dir="ltr">“She was a liar...that's really what we're both saying. She lied about it, she lied.”</p> <p dir="ltr">Anderson also claimed the comments made about what colour skin Meghan and Harry’s child would have - said by an unknown family member - happened before their engagement was announced, rather than while Meghan was pregnant.</p> <p dir="ltr">“It was an instant conversation about two people who are going...if they are going to be grandparents, Charles and Camilla [were] speculating on what the kids might look like,” he said.</p> <p dir="ltr">“Obviously, you have two very attractive people here and ‘Gee I wonder what colour their eyes will be, what their hair would be like.’ You know this kind of thing it was something I would say [was] relatively benign and witnessed by several people and then spun into something toxic.”</p> <p dir="ltr">Kelly added that the conversation between Charles and Camilla shouldn’t be considered racist.</p> <p dir="ltr">“You're just curious about how your baby's gonna look,” she said.</p> <p dir="ltr">“A negative judgement attached to a darker skin would be racist, but just wondering, that's not racist.”</p> <p><span id="docs-internal-guid-c7e4d5b4-7fff-8494-c3a3-25d07acece8a"></span></p> <p dir="ltr"><em>Images: Megyn Kelly (YouTube) / Spotify</em></p>

Excelling as a musician takes practice and requires opportunities – not just lucky genes

<p>What makes talented musicians so good at what they do?</p> <p>There’s plenty of evidence that people can be born that way. Research findings suggest that about <a href="https://doi.org/10.1136/jmg.2007.056366">half of musical ability is inherited</a>. Even if that’s true, it doesn’t mean you must have musical talent in your genes to excel on the bass, oboe or drums. </p> <p>And even if you’re fortunate enough to belong to a family that includes musicians, you would still need to study, practice and get expert guidance to play well. </p> <p>As a <a href="https://scholar.google.com/citations?user=34DZlUIAAAAJ&amp;hl=en&amp;oi=ao">music professor and conductor</a>, I’ve seen the role that practice and experience play in propelling musicians toward mastery and success. There are some factors that help a musician get started – and heredity could be one of them. But musical skill is ultimately a complex interplay between <a href="https://doi.org/10.1177%2F0022429416680096">lots of practice and high-quality instruction</a>.</p> <h2>The role genes can play</h2> <p>Of course many great musicians, including some who are world famous, are related to other musical stars.</p> <p>Liza Minnelli, the famed actress, singer and dancer, is one of the late entertainer <a href="https://hollywoodlife.com/feature/judy-garland-kids-4728886/">Judy Garland’s three children</a>. <a href="https://people.com/music/jon-batiste-everything-to-know">Jon Batiste</a> – “The Late Show” bandleader, pianist and composer who has won Emmy, Oscar and Golden Globe awards – has at least 25 musicians in his family.

Researchers have found that it <a href="https://doi.org/10.1086/301704">may be hereditary</a>. But do you need it to be a great musician? Not really.</p> <h2>Most people are born with some musical ability</h2> <p>I define musical ability as the possession of talent or potential – the means to achieve something musical.</p> <p>Then there’s skill, which I define as what you attain by working at it.</p> <p>You need at least some basic musical ability to acquire musical skills. Unless you can hear and discern pitches and rhythms, you can’t reproduce them.</p> <p>But people may overestimate the role of genetics because, with very rare exceptions, <a href="https://www.apa.org/monitor/feb05/absolute">almost everyone can perceive pitches</a> and rhythms.</p> <p>My research regarding children’s musicality suggests measures of singing skills are <a href="https://doi.org/10.1177/0022429416666054">normally distributed</a> in the population. That is, pitch ability follows a <a href="https://www.investopedia.com/terms/b/bell-curve.asp">bell curve</a>: Most people are average singers. Not many are way below average or excellent. </p> <p>My team’s most recent research suggests that this distribution is <a href="https://doi.org/10.1177/00224294211032160">true for rhythm</a> in addition to pitch. </p> <p>Not surprisingly, some musical skills are correlated.</p> <p>The more training you have on specific musical skills, the <a href="https://doi.org/10.1177/00224294211011962">better you’ll test on certain others</a>. This is probably because musical experience enhances other musical abilities.</p> <p>To sum it up, an emerging body of research indicates that practice doesn’t make perfect. But for most people, it helps a lot.</p> <h2>Lessons and practice are essential</h2> <p>What about people who say they they can’t keep a beat? It turns out that they almost always can track a steady beat to music. They just haven’t done it enough.</p> <p>Indeed, the last time I gave a nonbeliever our lab’s test for rhythm perception, she performed excellently. For that and for singing, some people just need <a href="https://www.nytimes.com/2020/01/21/magazine/how-to-sing-in-tune.html">a little help</a> to move past assumptions they lack talent: You can’t say you’re incapable of something if you haven’t spent time trying. </p> <p>Some researchers and <a href="https://strategiesforinfluence.com/malcolm-gladwell-10000-hour-rule/">journalists have promoted</a> the idea it takes <a href="https://doi.org/10.1037/0033-295X.100.3.363">10,000 hours of practice or training to master</a> a new skill. </p> <p>Innate ability puts people at different starting lines toward musical mastery. But once you’ve started to study an instrument or singing style, skill development depends on many other factors. Getting lessons, practicing often and being in a musical family may make those more likely.</p> <p>For example, Lizzo, a hip-hop superstar and classically trained flute player, had the luck to <a href="https://www.thefamouspeople.com/profiles/lizzo-44986.php">grow up in family of music lovers</a>. They all had their own taste in music. Her success is a microcosm of why a well-rounded musical education for young people matters.</p> <p>The singers in the choir I lead at Penn State have a range of experience, from a little to a lot. Yet soon after they join it, they develop the ability to <a href="https://doi.org/10.1177/87551233211040726">pick a good key and starting pitch</a> as they get to know their own voices. </p> <p>Practicing more doesn’t change your baseline potential, it just changes what you can presently do. That is, if you practice a specific song over and over again, eventually you’re going to get better at it.</p> <p>Jonathon Heyward, the Baltimore Symphony’s new conductor, who has <a href="https://www.nytimes.com/2022/07/21/arts/music/jonathon-heyward-baltimore-symphony-orchestra.html">no musicians in his family</a>, has worked really hard to excel. He started taking cello lessons at age 10 and hasn’t stopped since, playing and practicing and studying.</p> <h2>Privilege can play a role</h2> <p>Socioeconomic factors can also enter the equation. While conducting research, I’ve seen high-income college students from high-income families, with more years of musical experience, perform better than their classmates who have lower-income backgrounds and had fewer opportunities.</p> <p>Genes can give someone a head start. At the same time, having a quiet space where you can practice on an acoustic instrument or a digital workstation might make a more decisive difference for the musical prospects of most children. The same goes for having money for private lessons or access to free classes.</p> <p>Even so, many of the best musicians, including jazz greats <a href="https://www.louisarmstronghouse.org/biography/">Louis Armstrong</a> and <a href="https://www.pbs.org/wnet/americanmasters/billie-holiday-about-the-singer/68/">Billie Holiday</a>, grew up facing many hardships.</p> <p>With the right conditions for practice and gaining experience, who knows where the next Liza or Lizzo will come from.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/excelling-as-a-musician-takes-practice-and-requires-opportunities-not-just-lucky-genes-186693" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Keeping to the beat controlled by 69 genes – not just our feet

<p class="spai-bg-prepared">Are you a dancing queen or do you have two left feet?

Kelly Slater’s former beachside stay goes under the hammer

<p dir="ltr">The coastal home that hosted US surfing champion Kelly Slater has been listed for sale.</p> <p dir="ltr">It isn’t the only reason Slater has been in the news lately, after he made waves when he spoke out against the Australian government’s <a href="https://www.oversixty.com.au/travel/travel-trouble/those-are-the-rules-kelly-slater-barred-from-australia" target="_blank" rel="noopener">handling of Novak Djokovic’s deportation</a> and its response to the NSW flood crisis, which he said was “nothing short of appalling”.</p> <p dir="ltr">The home’s current owner, former Quiksilver International boss Bruce Raymond, has listed the home with plans to stay local following the sale. Raymond, who learned how to surf when he was just four-years-old, has lived near the beach all his life and continues to surf everyday.</p> <p dir="ltr">“This was to be our forever home but I’m scaling down now.

Some endangered species can no longer survive in the wild. So should we alter their genes?

<p>Around the world, populations of many beloved species are declining at increasing rates. According to one <a href="https://www.theguardian.com/environment/2020/sep/30/world-plant-species-risk-extinction-fungi-earth">grim projection</a>, as many as 40% of the world’s species may be extinct by 2050. Alarmingly, many of these declines are caused by threats for which few solutions exist.</p> <p>Numerous species now depend on conservation breeding programs for their survival. But these programs typically do not encourage species to adapt and survive in the wild alongside intractable threats such as climate change and disease.</p> <p>This means some species can no longer exist in the wild, which causes major downstream effects on the ecosystem. Consider, for example, how a coral reef would struggle to function without corals.</p> <p>What if there was another way? My colleagues and I have developed an intervention method that aims to give endangered species the genetic features they need to survive in the wild.</p> <p><img src="https://images.theconversation.com/files/411140/original/file-20210714-13-1bf7ccv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="bleached coral with fish" /> <span class="caption">Genetically altering coral may help them survive in a warmer world.</span> <span class="attribution"><span class="source">Rick Stuart-Smith</span></span></p> <h2>Bringing theory into practice</h2> <p>Over generations, natural selection enables species to adapt to threats. But in many instances today, the speed at which threats are developing is outpacing species’ ability to adapt.</p> <p>This problem is especially apparent in wildlife threatened by newly emerging infectious diseases such as chytridiomycosis in amphibians, and in climate-affected species such as corals.</p> <p>The toolkit my colleagues and I developed is called “targeted genetic intervention” or TGI. It works by increasing the occurrence or frequency of genetic features that impact an organism’s fitness in the presence of the threat. We outline the method in a recent <a href="https://www.sciencedirect.com/science/article/abs/pii/S0169534721003384">research paper</a>.</p> <p>The toolkit involves <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/artificial-selection">artificial selection</a> and <a href="https://www.frontiersin.org/articles/10.3389/fbioe.2019.00175/full">synthetic biology</a>. These tools are well established in agriculture and medicine but relatively untested as conservation tools. We explain them in more detail below.</p> <p>Many tools in our TGI toolkit have been discussed in theory in conservation literature in recent decades. But rapid developments in genome sequencing and synthetic biology mean some are now possible in practice.</p> <p>The developments have made it easier to understand the genetic basis of features which enable a species to adapt, and to manipulate them.</p> <p><img src="https://images.theconversation.com/files/442166/original/file-20220124-19-xc82dx.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="frog on wet rock" /> <span class="caption">Some animal species cannot adapt in time to survive threats such as disease.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>What is artificial selection?</h2> <p>Humans have long used artificial (or phenotypic) selection to promote desirable characteristics in animals and plants raised for companionship or food. This genetic alteration has led to organisms, such as domestic dogs and maize, that are dramatically different from their wild progenitors.</p> <p>Traditional artificial selection can lead to outcomes, such as high inbreeding rates, that affect the health and resilience of the organism and are undesirable for conservation. If you’ve ever owned a purebred dog, you might be aware of some of these genetic disorders.</p> <p>And when it comes to conservation, determining which individuals from a species are resistant to, say, a deadly pathogen would involve exposing the animal to the threat – clearly not in the interests of species preservation.</p> <p>Scientists in the livestock industry have developed a new approach to circumvent these problems. Called genomic selection, it combines data from laboratory work (such as a disease trial) with the genetic information of the animals to predict which individuals bear genetic features conducive to adaptation.</p> <p>These individuals are then chosen for breeding. Over subsequent generations, a population’s ability to survive alongside pervasive threats increases.</p> <p>Genomic selection has led to disease-resistant salmon and livestock that produce more milk and better tolerate heat. But it is yet to be tested in conservation.</p> <p><img src="https://images.theconversation.com/files/442161/original/file-20220124-27-11vyq0z.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="cows in green field" /> <span class="caption">Artificial selection has been used to develop traits that humans desire in livestock.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>What is synthetic biology?</h2> <p><a href="https://www.genome.gov/about-genomics/policy-issues/Synthetic-Biology">Synthetic biology</a> is a toolkit for promoting change in organisms. It includes methods such as transgenesis and gene editing, which can be used to introduce lost or novel genes or tweak specific genetic features.</p> <p>Recent synthetic biology tools such as <a href="https://medlineplus.gov/genetics/understanding/genomicresearch/genomeediting/">CRISPR-Cas9</a> have created a buzz in the medical world, and are also starting to gain the <a href="https://portals.iucn.org/library/node/48408">attention</a> of conservation biologists.</p> <p>Such tools can accurately tweak targeted genetic features in an individual organism – making it more able to adapt – while leaving the rest of the genome untouched. The genetic modifications are then passed on to subsequent generations.</p> <p>The method reduces the likelihood of unintended genetic changes that can occur with artificial selection.</p> <p>Synthetic biology methods are currently being trialled for conservation in multiple species around the world. These include the <a href="https://www.esf.edu/chestnut/resistance.htm">chestnut tree</a> and black-footed <a href="https://neo.life/2021/05/cloning-wildlife-and-editing-their-genes-to-protect-them-and-us/">ferrets</a> in the United States, and <a href="https://theconversation.com/gene-editing-is-revealing-how-corals-respond-to-warming-waters-it-could-transform-how-we-manage-our-reefs-143444">corals</a> in Australia.</p> <p>I am working with researchers at the University of Melbourne to develop TGI approaches in Australian frogs. We are trialling these approaches in the iconic southern corroboree frog, and plan to extend them to other species if they prove effective.</p> <p>Worldwide, the disease chytridiomycosis is devastating frog populations. Caused by the fungal pathogen <em>Batrachochytrium dendrobatidis</em>, it has led to the extinction of about <a href="https://www.nationalgeographic.com/animals/article/amphibian-apocalypse-frogs-salamanders-worst-chytrid-fungus">90 frog species</a> and declines in as many as 500 others.</p> <p>Many frog species now rely on conservation breeding for their continued survival. No effective solution for restoring chytrid-susceptible frogs to the wild exists, because the fungus cannot be eradicated.</p> <p><img src="https://images.theconversation.com/files/442155/original/file-20220124-23-cebr8a.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="gloved hand removed portion of DNA strand" /> <span class="caption">CRISPR technology could potentially be used to edit the genes of endangered species.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Looking ahead</h2> <p>As with many conservation approaches, targeted genetic intervention is likely to involve trade-offs. For example, genetic features that make a species resistant to one disease may make it more susceptible to another.</p> <p>But the rapid rate of species declines means we should trial such potential solutions before it’s too late. The longer species are absent from an ecosystem, the greater the chance of irreversible environmental changes.</p> <p>Any genetic intervention of this type should involve all stakeholders, including Indigenous peoples and local communities. And caution should be taken to ensure species are fit for release and pose no risk to the environment.</p> <p>By bringing the concept of TGI to the attention of the public, government, and other scientists, we hope we will spur discussion and encourage research on its risks and benefits.<!-- Below is The Conversation's page counter tag.
