Making art is a uniquely human act, and one that provides a wellspring of health benefits

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/girija-kaimal-1486183">Girija Kaimal</a>, <a href="https://theconversation.com/institutions/drexel-university-1074">Drexel University</a> When you think about the word “art,” what comes to mind? A child’s artwork pinned to the fridge? A favorite artist whose work always inspires? Abstract art that is hard to understand? Each of these assumes that making art is something that other people do, such as children or “those with talent.” However, as I explain in my book “<a href="https://global.oup.com/academic/product/the-expressive-instinct-9780197646229?q=the%20expressive%20instinct&lang=en&cc=ca">The Expressive Instinct</a>,” art is intrinsic to human evolution and history. Just as sports or workouts exercise the body, creating art exercises the imagination and is essential to mental as well as physical well-being. I am a <a href="https://scholar.google.com/citations?user=C8R2XOYAAAAJ&hl=en">professor of art therapy</a> who studies how creative self-expression affects physical and emotional health. In our clinical research studies, my colleagues and I are finding that any form of creative self-expression – including drawing, painting, fiber arts, woodworking or photography – can <a href="https://doi.org/10.1080/08322473.2017.1375827">reduce stress</a>, improve mood and increase self-confidence. As a sickly child who needed to stay home from school a lot, I found that making art helped me cope. Today, creating art is my sanctuary. I use it as a sounding board to better understand myself and a way to recharge and learn from the challenges of life. <h2>The uniquely human attribute of creativity</h2> Although everyone has their own concept of what defines art, one thing is universally true: Creativity is a defining feature of the human species. How so? Well, human brains are not computers processing data. They are biological prediction machines that perceive the environment through memories and the senses, with the capacity to <a href="https://doi.org/10.3389/fnhum.2010.00025">use that information to imagine</a> plausible future scenarios. These inherent predictive and imaginative capacities are the wellspring of humanity’s abilities to survive and thrive – because self-expression is a safety valve that helps us cope with uncertainty. No one truly knows the future; they must live each day not sure of what will happen tomorrow. Art can help us all practice this imaginative muscle in a useful way. In our study examining brain activity while using virtual reality tools to create 3-D digital artwork, my team demonstrated that <a href="https://doi.org/10.1080/07421656.2021.1957341">creative expression is a natural state of being</a>. The brain naturally uses fewer cognitive resources to be expressive and creative, compared with the <a href="https://doi.org/10.1080/07421656.2021.1957341">brain power needed to do a rote task</a> that requires conscious effort. Seemingly ordinary everyday activities can provide opportunities to tap into one’s natural creativity and imagination: whipping up a meal from leftovers, figuring out an alternate route to work, dancing a little jig in response to hearing a song, or planting and tending a garden. We have repeatedly found in our studies that even a single session of real and honest self-expression can improve self-confidence and <a href="https://doi.org/10.1177/1534735420912835">reduce feelings of stress</a>, <a href="https://doi.org/10.1016/j.ejon.2019.08.006">anxiety and burnout</a>. This is partly because <a href="https://doi.org/10.1016/j.aip.2017.05.004">creativity activates reward pathways</a> in the brain. Using our hands and bodies to express ourselves activates dopamine pathways and helps us feel good. Dopamine is a neural messenger that is associated with feeling a <a href="https://doi.org/10.1016%2Fj.ajpath.2015.09.023">sense of hope, accomplishment or reward</a>. Our brains are wired to secrete <a href="https://theconversation.com/why-does-experiencing-flow-feel-so-good-a-communication-scientist-explains-173505">feel-good hormones whenever we move</a>, create something or engage in any type of expressive activity. Tapping into the creative resources within is <a href="https://theconversation.com/drawing-making-music-and-writing-poetry-can-support-healing-and-bring-more-humanity-to-health-care-in-us-hospitals-204684">one of the most underrated seeds of well-being</a> in the world. By comparison, bottling up or <a href="https://www.scientificamerican.com/article/why-the-secrets-you-keep-are-hurting-you/">denying these feelings can cause distress</a>, anxiety and fear because we have not processed and expressed them. This is probably one of the reasons why every community around the world has its own creative and expressive practices. Even our ancestors in Indigenous communities all around the world intuitively knew that <a href="https://doi.org/10.1016/j.aip.2021.101879">self-expression was essential</a> to emotional health and social connection. Being unable to share our lives, <a href="https://www.scientificamerican.com/article/why-the-secrets-you-keep-are-hurting-you/">keeping secrets</a> and feeling isolated and lonely tend <a href="https://doi.org/10.1016/j.neubiorev.2020.02.002">to worsen our health</a>. To our brains, social isolation feels like a chronic disease because it interprets this loneliness and inability to express as a threat to survival. Since creative expression can engage the senses, it can also be a body workout: a sensual as well as emotional and cognitive experience. Being active in expression – be it art, music, dance, drama, writing, culinary arts or working with nature – imparts a sense of confidence and hope that <a href="https://global.oup.com/academic/product/the-expressive-instinct-9780197646229?q=the%20expressive%20instinct&lang=en&cc=ca">challenges can be navigated and overcome</a>. <h2>The role of art therapy</h2> Given the integral role of art in our lives, it makes sense that making art can help people manage transitions, adversity and trauma, such as the stresses of puberty, the death of a loved one or <a href="https://doi.org/10.1016/j.ejon.2019.08.006">experiencing a serious illness</a>. According to a global study, 1 in 2 people will experience a <a href="https://doi.org/10.1016/S2215-0366(23)00193-1">mental-health-related challenge in their lifetime</a>, whether from life’s challenges, genetic predispositions or a combination of the two. This is where art therapy can come in. Art therapy is <a href="https://arttherapy.org/about-art-therapy/">a regulated mental health profession</a> in which clinical psychotherapists with extensive clinical training offer psychotherapy to patients with diagnosed mental health needs. The origins of art therapy go back to <a href="https://doi.org/10.1136/bmjopen-2017-021448">attempts to treat soldiers struggling with post-traumatic stress</a> during the 20th century’s two world wars. Today there is evidence that traumatic experiences tend to be stored as <a href="http://orcid.org/0000-0002-7316-0473">sounds, images and physical sensations</a> in the brain. When someone <a href="https://doi.org/10.1001/jama.2019.20825">lacks the words</a> to process these experiences through traditional talk therapy, art therapy can provide an indirect way to express and externalize those feelings and memories. <figure><iframe src="https://www.youtube.com/embed/e-IiUcUVAwk?wmode=transparent&start=3" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>The process of making art can help people process feelings that they aren’t able to put into words.</figcaption></figure> One of art therapy’s unique strengths is that it provides nonverbal ways of communicating, processing and eventually managing the symptoms of post-traumatic stress disorder, or PTSD. In fact, in a recent study, my team has found that a personal history of trauma is related to <a href="https://doi.org/10.3389/fpsyg.2024.1337927">how people react to evocative images</a>. Images of distress and pain resonate with us when we have known similar kinds of distress ourselves. This implies that our life stories make us sensitized to distress in others and even personalize it more. Creative self-expression is especially relevant in coping with trauma because it provides an outlet through which a person <a href="https://doi.org/10.1177/1534735420912835">can regain a sense of agency</a> and control. <h2>How to bring creativity into daily life</h2> For those new to exploring art as a creative pursuit or for well-being reasons, engaging in creative activities begins with letting go of unrealistic expectations. Being creative isn’t about becoming a famous artist or even a mediocre one. It is about allowing ourselves to flex the creative muscle that we all have and enjoying all the sensory and emotional aspects of imagining. Next, think about activities that made you feel free to explore when you were a child. Did you like singing, playing in the outdoors, dancing, making up pretend plays, or writing little tales? Allow yourself to indulge in any and all of these creative pursuits that made you feel relaxed and joyful. A <a href="https://doi.org/10.1016/j.aip.2021.101879">cultural tradition</a>, tinkering with electronics, making a gift for someone or simply paying attention to everyday beauty – any of these can be a creative activity. And just like any muscle, the more you exercise it, the stronger it becomes. Over time, you will notice yourself getting more confident and adventurous in your creative practices. Whatever it is, make time for this creative pursuit every week – which is possibly the hardest step of them all. If it seems “unimportant” compared with the demands of daily life, such as work or family, try thinking of it as another form of sustenance. Remember that creativity is just as critical to human health as <a href="https://theconversation.com/helping-children-eat-healthier-foods-may-begin-with-getting-parents-to-do-the-same-research-suggests-225157">eating nutritious meals</a> or <a href="https://theconversation.com/yoga-modern-research-shows-a-variety-of-benefits-to-both-body-and-mind-from-the-ancient-practice-197662">getting exercise</a> and <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">good rest</a>. So as the Latin saying goes: “Plene vivere.” Live fully.  <a href="https://theconversation.com/profiles/girija-kaimal-1486183">Girija Kaimal</a>, Professor of Art Therapy Research, <a href="https://theconversation.com/institutions/drexel-university-1074">Drexel University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mind

It may be macabre, but dark tourism helps us learn from the worst of human history

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/dr-neil-robinson-1312179">Dr Neil Robinson</a>, <a href="https://theconversation.com/institutions/university-of-salford-878">University of Salford</a> Dark tourism has become a much more well-covered pasttime in recent years, in which a macabre fascination lead tourists to travel to various places not served by Thomas Cook: the sites of battles and genocides, war cemeteries, prisons, and even <a href="http://www.theatlantic.com/international/archive/2014/07/the-rise-of-dark-tourism/374432/">current warzones such as Syria</a>. The 20th century alone has provided such a <a href="http://www.therichest.com/expensive-lifestyle/location/10-great-places-to-visit-for-dark-tourism/">long list of places</a> at which catastrophes or great loss of life and suffering has occurred. Sites visited range from the spot from which JFK was assassinated, to prisons such as Alcatraz in San Francisco, through to battlefields of the World Wars, or the vestiges of genocides such at Auschwitz in Poland or Tuol Sleng in Phnom Penh, Cambodia. It’s not everybody’s cup of tea, but we shouldn’t condemn those for whom this is an interest. Dark tourism appears to be a manifestation of our media-rich society through which information found online may persuade us to see historical sites in person. But its origins can be traced back much further than the fascination with death and disasters of the 19th and 20th century. In the 11th century, people and pilgrims often visited places with religious significance such as Jerusalem, where the location of Christ’s crucifixion is a popular attraction; tourists visited Gettysburg, the site of the bloodiest battle of the American Civil War in 1863; and in more recent centuries, the Grand Tour offered an opportunity for the wealthy to experience Europe, with sites such as the classical ruins of the Colosseum in Rome – which in the name of entertainment saw execution, torture and death – one of the must-see attractions. Today, in parallel with the growth in popularity of dark tourism is the enormous growth of social media and the 24-hour news economy. The ease of access to such blanket coverage through the web, Facebook and Twitter has increased people’s awareness of, and fascination for, these historical sites of war, conflict and catastrophe. For example, the last decade has brought a surge in visitor numbers to <a href="https://theconversation.com/from-fiction-to-gallows-humour-how-chernobyl-survivors-are-still-coping-with-trauma-57923">Chernobyl</a>, where guides take visitors around the abandoned city of Pripyat (radiation levels permitting) which has been deserted since the nuclear power plant explosion on April 26, 1986. The 30th anniversary this year has in itself <a href="http://www.dailymail.co.uk/travel/travel_news/article-3526271/Chernobyl-tourists-pose-photos-eerie-sites.html">added to interest in visiting</a> the overgrown and crumbling city. As with tourism of any kind, this greater footfall brings benefits. In this case, not just the economic boost but also as a tool of education and even conflict resolution. For example, the <a href="http://www.belfasttours.com/package/belfast-political-mural-tour">taxi tours of Belfast’s murals</a>, which document Northern Ireland’s Troubles, offer visitors a way to understand the history and provide the communities involved a means to reflect and move on from the conflict. This model is <a href="http://www.h-net.org/reviews/showpdf.php?id=25852">viewed with interest</a> and hope by moderates on both sides of the Arab-Israeli divide searching for a peaceful solution for the long term. The tours of <a href="http://whc.unesco.org/en/list/916">Robin Island prison</a> in South Africa, where Nelson Mandela spent 18 years incarcerated among many others, starkly present how those imprisoned by a corrupt and discriminatory political regime can later engage in peace and reconciliation. The <a href="http://www.bruisedpassports.com/africa/5-reasons-you-must-go-for-a-township-tour-in-south-africa">Soweto township tours</a> in Johannesburg have acted in part as a means through which generations of South Africans can better understand their country’s dark past and help to establish truth and reconciliation for the future. Dark tourism should not in my opinion by viewed as unethical, repugnant or even a self-indulgent activity. Certainly some dark tourists may engage in their pursuits for all the wrong reasons, seeing death and destruction as a commodity to be consumed with little thought for those who caught up in its wake. But others visit such sites to pay their respects, to better understand the magnitude of death and destruction, and to inform the outside world of the details of terrible events – even in some case offering to help. These are positive effects that may come from so much pain and suffering. We should strive to better understand the origins of the terrible events of human history to be more able to prevent us repeating them. In this regard, that more people visit sites associated with dark tourism and learn about them should be seen as a positive.<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/60966/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dr-neil-robinson-1312179">Dr Neil Robinson</a>, Lecturer in Business, <a href="https://theconversation.com/institutions/university-of-salford-878">University of Salford</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Trouble

Julian Assange has been in the headlines for almost two decades. Here’s why he’s such a significant public figure

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/matthew-ricketson-3616">Matthew Ricketson</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> “The price of freedom is eternal vigilance” is a famous quotation usually attributed to Thomas Jefferson, a founder of US democracy. For Julian Assange, the price of freedom has been five years in jail while he fought extradition to the United States to face charges no democracy worthy of the name should ever have brought. It is profoundly heartening news to see Assange’s release from London’s Belmarsh prison and flight home to Australia via a US territory in the western pacific. He’ll face a hearing and sentencing <a href="https://theconversation.com/julian-assange-plea-deal-what-does-it-mean-for-the-wikileaks-founder-and-what-happens-now-233207">this morning</a> in Saipan in the Northern Mariana Islands, to formalise a plea deal with the US government. It is profoundly disheartening, though, to see the lengths to which a nation state has gone to punish a publisher who released documents and videos that revealed US troops allegedly committing war crimes in the Iraq war two decades ago. Assange has been a controversial international figure for so many years now it’s easy to lose sight of what he has done, why he attracted such fiercely polarised views, and what his incarceration means for journalism and democracy. <h2>What did he do?</h2> Assange, an Australian national, came to prominence in the 2000s for setting up <a href="https://wikileaks.org/">WikiLeaks</a>, a website that published leaked government, military and intelligence documents disclosing a range of <a href="https://www.bbc.com/news/technology-47907890">scandals</a> in various countries. Most of the documents were released in full. For Assange, this fulfilled his aim of radical transparency. For critics, it led to the release of documents that could <a href="https://www.aljazeera.com/news/2011/9/3/wikileaks-criticised-over-uncensored-cables">endanger the lives</a> of intelligence sources. This remains a point of contention. Some have asserted Assange’s attitude toward those named in leaked documents was cavalier and that the publication of some documents was <a href="https://apnews.com/article/b70da83fd111496dbdf015acbb7987fb">simply unnecessary</a>. But critics, especially those in the US military, have been unable to point to <a href="https://theconversation.com/a-new-book-argues-julian-assange-is-being-tortured-will-our-new-pm-do-anything-about-it-183622">specific instances</a> in which the release of documents has led to a person’s death. In 2010, Joe Biden, the then vice-president, <a href="https://www.nbcnews.com/id/wbna40702904">acknowledged</a> WikiLeaks’ publications had caused “no substantive damage”. Then US Defense Secretary Robert Gates <a href="https://www.npr.org/2019/04/12/712659290/how-much-did-wikileaks-damage-u-s-national-security">said</a> at the time countries dealt with the US because it was in their best interests, “not because they believe we can keep secrets”. The key to WikiLeaks’ success was that Assange and his colleagues found a way to <a href="https://www.bbc.com/news/technology-11026659">encrypt the documents</a> and make them untraceable, to protect whistleblower sources from official retribution. It was a strategy later <a href="https://www.theguardian.com/technology/2014/jun/05/guardian-launches-securedrop-whistleblowers-documents">copied</a> by mainstream media organisations. WikiLeaks became famous around the globe in April 2010 when it released hundreds of thousands of <a href="https://www.bbc.com/news/technology-47907890">documents</a> in tranches known as the Afghan war logs, the Iraq war logs and Cablegate. They revealed numerous alleged war crimes and provided the raw material for a shadow history of the disastrous wars waged by the Americans and their allies, including Australia, in Afghanistan and Iraq following the September 11 2001 terrorist attacks. Documents are one thing, video another. Assange released <a href="https://upload.wikimedia.org/wikipedia/commons/transcoded/6/61/CollateralMurder.ogv/CollateralMurder.ogv.360p.vp9.webm">a video</a> called “Collateral Murder”. It showed US soldiers in a helicopter shooting and killing Iraqi civilians and two Reuters journalists in 2007. Apart from how the soldiers in the video speak – “Hahaha, I hit them”, “Nice”, “Good shot” – it looks like most of the victims are civilians and the journalists’ cameras are mistaken for rifles. When one of the wounded men tries to crawl to safety, the helicopter crew, instead of allowing their US comrades on the ground to take him prisoner as required by <a href="https://www.icrc.org/en/rules-of-war">the rules of war</a>, seeks permission to shoot him again. <hr /> <iframe id="tc-infographic-1064" class="tc-infographic" style="border: none;" src="https://cdn.theconversation.com/infographics/1064/0f0903c8d2249ac24316f2a86f5e0f231b6546e6/site/index.html" width="100%" height="400px" frameborder="0"></iframe> <hr /> The soldiers’ request for authorisation to shoot is granted. The wounded man is carried to a nearby minibus, which is then shot to pieces with the helicopter’s gun. The driver and two other rescuers are killed instantly while the driver’s two young children inside are seriously wounded. US army command investigated the matter, <a href="https://theconversation.com/a-new-book-argues-julian-assange-is-being-tortured-will-our-new-pm-do-anything-about-it-183622">concluding</a> the soldiers acted in accordance with the rules of war. Despite this, US prosecutors <a href="https://www.theguardian.com/media/2020/jun/15/julian-assange-indictment-fails-to-mention-wikileaks-video-that-exposed-us-war-crimes-in-iraq">didn’t include</a> the video in its indictment against Assange, leading to accusations it didn’t want such material further exposed in public. Equally to the point, the public would never have known an alleged war crime had been committed without the release of the video. <h2>Going into exile</h2> Assange and WikiLeaks had no sooner become famous than it all began to come to a halt. He was alleged to have sexually assaulted <a href="https://www.bbc.com/news/world-europe-50473792">two women</a>. He holed up the <a href="https://www.nytimes.com/2012/08/17/world/americas/ecuador-to-let-assange-stay-in-its-embassy.html">Ecuadoran embassy</a> in London for <a href="https://apnews.com/article/7276b35e8d5944e7b5ca280ab0390b26">seven years</a> to avoid being extradited to Sweden for questioning over the alleged assaults, from where he could then be extradited to the US. Then he was <a href="https://mondediplo.com/2024/02/11assange">imprisoned in England</a> for the past five years. It has been confusing to following the byzantine twists and turns of the Assange case. His character has been reviled by his opponents and revered by his supporters. Even journalists, who are supposed to be in the same business of speaking truth to power, have adopted contradictory stances towards Assange, oscillating between giving him awards (a <a href="https://www.walkleys.com/board-statement-4-16/">Walkley</a> for his outstanding contribution to journalism) and shunning him (<a href="https://www.nytimes.com/2019/05/23/opinion/julian-assange-wikileaks.html">The New York Times</a> has said he is a source rather than a journalist). <h2>Personal suffering</h2> After Sweden eventually <a href="https://www.bbc.com/news/world-europe-50473792">dropped</a> the sexual assault charges, the US government swiftly ramped up its request to extradite Assange to face charges under the Espionage Act, which, if successful, could have led to a jail term of up to <a href="https://www.theguardian.com/media/article/2024/jun/25/explainer-who-is-julian-assange-and-what-are-the-details-of-his-plea-deal#:%7E:text=After%20his%20departure%20from%20the,to%20175%20years%20in%20prison.">175 years</a>. Until this week, most of the recent headlines about Assange have been about this extradition attempt. Most recently, he was granted the <a href="https://theconversation.com/julian-assanges-appeal-to-avoid-extradition-will-go-ahead-it-could-be-legally-groundbreaking-227859">right to appeal</a> the UK Home Secretary’s order that he be extradited to the US. This brings us to now, where if all goes according to legal planning, Assange will <a href="https://theconversation.com/julian-assange-plea-deal-what-does-it-mean-for-the-wikileaks-founder-and-what-happens-now-233207">plead guilty</a> to one count under the US Espionage Act, then fly back to Australia. But the long, protracted and very public case, legal or otherwise, has raised questions yet to be fully reckoned with. Nils Melzer, the United Nations Special Rapporteur on Torture, thoroughly investigated the case against Assange and laid it out in forensic detail in a <a href="https://theconversation.com/a-new-book-argues-julian-assange-is-being-tortured-will-our-new-pm-do-anything-about-it-183622">2022 book</a>. In it, he wrote: <blockquote> The Assange case is the story of a man who is being persecuted and abused for exposing the dirty secrets of the powerful, including war crimes, torture and corruption. It is a story of deliberate judicial arbitrariness in Western democracies that are otherwise keen to present themselves as exemplary in the area of human rights. </blockquote> He’s also suffered significantly in legal and diplomatic processes in at least four countries. Since being imprisoned in 2019, <a href="https://www.theguardian.com/media/article/2024/jun/25/julian-assange-plea-deal-with-us-free-to-return-australia#:%7E:text=WikiLeaks%20said%20on%20X%20that,isolated%2023%20hours%20a%20day%E2%80%9D">Assange’s team says</a> he’s spent much of that time in solitary confinement for up to 23 hours a day, has been denied all but the most limited access to his legal team, let alone family and friends, and was kept in a <a href="https://www.bbc.com/news/uk-54060427">glass box</a> during his seemingly interminable extradition hearing. His physical and mental health have suffered to the point where he has been put on <a href="https://www.cbsnews.com/news/wikileaks-julian-assange-at-very-high-risk-of-suicide-attempt-psychiatric-expert-tells-court/">suicide watch</a>. Again, that seems to be the point, as Melzer writes: <blockquote> The primary purpose of persecuting Assange is not – and never has been – to punish him personally, but to establish a generic precedent with a global deterrent effect on other journalist, publicists and activists. </blockquote> So while Assange himself is human and his suffering real, his lengthy time in the spotlight have turned him into more of a symbol. This is true whether you think of him as the hero exposing the dirty secrets of governments, or as something much more sinister. If his experience has taught us anything, it’s that speaking truth to power can come at an unfathomable personal cost.<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/233232/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/matthew-ricketson-3616">Matthew Ricketson</a>, Professor of Communication, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Vianney Le Caer/Shutterstock Editorial This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Police appeal for help in solving discovery of mystery body

Last July, a farmer was clearing bushland on a property between Clifton Beach and Goats Beach in Tasmania, when he made a grisly discovery. He found skeletal remains along with a number of personal items believed to belong to the deceased. “Police attended and recovered the remains, which showed no signs of physical injuries,” Sergeant Lee Taylor said. The remains had been in the area between five and 50 years, according to police. “A forensic examination at the scene located several items with the remains, including a pair of black dress shoes with several store-bought orthotics in the heel, a short sleeve top and unreadable identification paperwork, and an old campsite nearby which may be related,” Taylor said. Forensic analysis of the remains found that they belonged to a Caucasian male , but no DNA matches were made, with police having to use facial reconstruction and releasing the image to the public, in hopes that someone could identify him. “With DNA taken from the remains not matching to any DNA comparisons, state or nationally, Australian Federal Police have provided a craniofacial reconstruction of the man’s potential appearance,” Taylor said. Anybody with information or who can identify the man is asked to contact the police. Images: 7News

Hope: A double-edged sword in the human experience

Hope has long been cherished as a source of strength in times of adversity. Yet, as explored in this edited extract from his new book The Human Condition by author Tony Grey, this fundamental emotion is not without its complexities and potential pitfalls. --- As in the host of challenges explored in The Human Condition, the feeling of expectation and desire for something beneficial to happen, which we call hope, is as fundamental to the human condition as the will to survive; they’re linked within the evolutionary imperative. As Cicero pointed out, “dum spiro spero” (while I breathe I hope). Hope is a rolling prayer to life as time moves on, a whisper to the soul that things will turn out all right. The sentiment is generally unchallenged. Why should it be? In times of trouble, we need the balm of hope. Samuel Johnson said, “Hope is a species of pleasure, and perhaps, the chief pleasure this world affords.” While usually positive about hope, Greek philosophers were sometimes ambivalent about it, citing its propensity, through wishful thinking, to encourage indolence or actually cause harm. In Sophocles’ play Antigone, the Chorus sings, “Hope whose wanderings are so wide is to many men a comfort, but to many a false lure of giddy desires.” Plato observes that hope breeds a confidence which can exacerbate a precondition of arrogance in the powerful, leading to serious wrongdoing. “It is among these men that we find the ones who do the greatest evils.” Napoleon and Hitler are examples. And so is the Japanese government responsible for the Pearl Harbour attack. At the World War Two surrender on the deck of the USS Missouri, a Japanese general was heard to say when he looked at the sky blackened by Allied aircraft flying past and the sea bursting with warships, “How did we ever hope we could win?” On the other hand, Plato stressed the motivational properties of hope when directed towards a good aim. And Aristotle links hope with the virtue of megalopsychia (high-mindedness) resulting from its inspirational role. I have an experience of this in my family. My nephew was born to my sister with intellectual disability, and other difficulties. His condition seemed hopeless. Nevertheless, from the first, hope was my sister’s support; it gave her the energy to carry on. Through the gloom it afforded a glimpse into the future where progress beckoned. And all along she demonstrated that hope is ineluctably linked to love. Aided by her husband, the father, she worked day and night teaching and inspiring the boy. When old enough he went to a special needs school and gradually progressed, indefatigably supported at home. Over time his condition improved so that eventually he could take and keep a simple job, cook food, and have friends (similarly disabled), a state absolutely unforeseeable at his early stage of life. Throughout all the difficulties, frustrations and threats of despair, hope sustained my sister and guided her to the wonderful achievement of saving a human life. In most instances, hope is personal in the sense that something specific to the individual or those who are close is wanted. However, it can range far beyond that into areas involving others such as team sports, politics, economic activity, justice, national and tribal identity, international relations – notably war, and pandemics like Covid. Within these fields, hope calls out for the survival and well-being of humanity and its prospects for moral and material progress. Such hope embraces faith in something bigger than the individual. If human beings have a purpose, its linked to that, and its fulfillment is somehow bound up in hope. This approach cries out for exploring a whole array of other challenges inherent in the human condition. ABOUT THE AUTHOR Tony Grey is an accomplished author residing in Sydney.

"An insult to human dignity": Mother of Bondi stabbing victim hits out at the media

The mother of Bondi stabbing victim Jade Young has hit out at how social media and major news outlets reported on her daughter's death. Jade Young, 47, was one of six people fatally stabbed by Joel Cauchi during his violent rampage at Bondi Junction Westfield on April 13th. Following the tragedy, graphic videos and images of the attacks were circulated online. Now, Jade's mother Elizabeth Young, writing in the <a href="https://www.smh.com.au/national/nsw/my-daughter-was-killed-in-the-bondi-junction-attack-how-my-family-found-out-is-shameful-20240429-p5fnbw.html" target="_blank" rel="noopener">Sydney Morning Herald</a> on Wednesday, said it was “shameful” how her family found out about Jade’s death. “Members of my family recognised Jade and her husband Noel in uncensored vision being played on a mainstream TV news feed, with vision of Jade lying on the ground at the shopping centre, receiving CPR,” she wrote. “The vision, shared on social media and picked up — and used by — multiple news media programs shared my daughter’s final moments with millions. Finding out that a loved one has been murdered is a horror that I do not wish on anyone. But seeing the vision of their last moments and knowing it has been broadcast to millions of people is an appalling breach of privacy and an insult to human dignity.” Ms Young went on to say how some of the major media organisations that shared violent images of the Bondi stabbing “approached our family within hours of the attack, offering their condolences … and the opportunity to share our family’s story”. “These same media organisations reported the failure of a certain popular social media platform to take down videos, without acknowledging their own complicity,” she said. “I am not surprised at their hypocrisy, but I am angry.” “Sharing violent images or personal material from the lives of victims of crime is not free speech — it is enormously profitable for some but it’s speech with a steep price for the victims,” she said. “Those who run social media platforms are remote from the pain inflicted by their uploads and the dystopia they have helped create. It is the victims who bear the cost.” Last week, hundreds of mourners attended a public memorial for Ms Young, an acclaimed architect and mother-of-two, where mourners were encouraged to wear colourful clothing “in memory of Jade”.

Elephant tourism often involves cruelty – here are steps toward more humane, animal-friendly excursions

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a> Suju Kali is a 50-year-old elephant in Nepal who has been carrying tourists for over 30 years. Like many elephants I encounter through my <a href="https://doi.org/10.1080/10888705.2022.2028628">research</a>, Suju Kali exhibits anxiety and can be aggressive toward strangers. She suffers from emotional trauma as a result of prolonged, commercial human contact. Like Suju Kali, many animals are trapped within the tourism industry. Some venues have no oversight and little concern for animal or tourist safety. Between 120,000 and 340,000 animals are used globally in a variety of wildlife tourism attractions, including <a href="https://doi.org/10.1371/journal.pone.0138939">endangered species</a> like elephants. Over a quarter of the world’s <a href="https://www.iucnredlist.org/species/7140/45818198">endangered elephants</a> reside in captivity with little oversight. Wildlife tourism – which involves viewing wildlife such as primates or birds in conservation areas, feeding or touching captive or “rehabilitated” wildlife in facilities, and bathing or riding animals like elephants – is <a href="https://doi.org/10.1080/14724049.2022.2156523">tricky business</a>. I know this because I am <a href="https://scholar.google.com/citations?user=YbweA2MAAAAJ&hl=en">a researcher studying human relationships with elephants</a> in both tourism and conservation settings within Southeast Asia. These types of experiences have long been an <a href="https://kathmandupost.com/money/2021/06/17/tourism-is-nepal-s-fourth-largest-industry-by-employment-study">extremely popular and profitable</a> part of the <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002074">tourism market</a>. But now, many travel-related organizations are urging people not to participate in, or <a href="https://www.usatoday.com/story/travel/destinations/2018/04/27/animal-welfare-travelers-how-enjoy-wildlife-without-harming/544938002/">calling for an outright ban on, interactive wildlife experiences</a>. Tourism vendors have started marketing more “ethical options” for consumers. Some are attempting to truly improve the health and welfare of wildlife, and some are transitioning captive wildlife into touch-free, non-riding or lower-stress environments. In other places, organizations are attempting to <a href="https://www.fao.org/documents/card/es/c/b2c5dad0-b9b9-5a3d-a720-20bf3b9f0dc2/">implement standards of care</a> or create manuals that outline good practices for animal husbandry. This marketing, academics argue, is often simply “<a href="https://doi.org/10.1016/j.gecco.2017.11.007">greenwashing</a>,” <a href="http://dx.doi.org/10.1080/13683500.2023.2280704">applying marketing labels to make consumers feel better</a> about their choices without making any real changes. Worse, research shows that some programs marketing themselves as ethical tourism may instead be widening economic gaps and harming both humans and other species that they are meant to protect. <h2>No quick fix</h2> For example, rather than tourist dollars trickling down to local struggling families as intended by local governments, many tourism venues are owned by nonresidents, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">meaning the profits do not stay in the area</a>. Likewise, only a small number of residents can afford to own tourism venues, and venues do not provide employment for locals from lower income groups. This economic gap is especially obvious in Nepalese elephant stables: Venue owners continue to make money off elephants, while elephant caregivers continue to work 17 hours a day for about US$21 a month; tourists are led to believe they are “<a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">promoting sustainability</a>.” Yet, there are no easy answers, especially for elephants working in tourism. Moving them to sanctuaries is difficult because with no governmental or global welfare oversight, elephants may end up in worse conditions. Many kindhearted souls who want to “help” elephants know little about their biology and mental health needs, or what it takes to keep them healthy. Also, feeding large animals like Suju Kali is pricey, <a href="https://doi.org/10.3390/ani14010171">costing around $19,000 yearly</a>. So without profits from riding or other income, owners – or would-be rescuers – can’t maintain elephants. Releasing captive elephants to the jungle is not a choice – many have never learned to live in the wild, so they cannot survive on their own. <h2>Hurting local people</h2> Part of the problem lies with governments, as many have marketed tourism as a way to fund conservation projects. For example in Nepal, a percentage of ticket sales from elephant rides are given to community groups to use for forest preservation and support for local families. Increasing demand for <a href="https://www.routledge.com/Tourism-and-Animal-Ethics/Fennell/p/book/9781032431826">wildlife-based tourism</a> may increase traffic in the area and thus put pressure on local governments to further limit local people’s access to forest resources. This may also lead to <a href="https://www.worldanimalprotection.org/latest/news/un-world-tourism-organisation-urged-create-better-future-animals/">increased demands on local communities</a>, as was the case in Nepal. In the 1970s, the Nepalese government removed local people from their lands in what is now Chitwan National Park as part of increasing “conservation efforts” and changed the protected area’s boundaries. Indigenous “Tharu,” or people of the forest, were forced to abandon their villages and land. While some were offered access to “buffer zones” in the 1990s, many remain poor and landless today. In addition, more and more desirable land surrounding conservation areas in Nepal is being developed for tourist-based businesses such as hotels, restaurants and shops, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">pushing local poor people farther away</a> from central village areas and the associated tourism income. Some activists would like humans to simply release all wildlife back into the wild, but <a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">there are multiple issues</a> with that. Elephant habitats throughout Southeast Asia have been transformed into croplands, cities or train tracks for human use. Other problems arise from the fact that tourism elephants have <a href="https://doi.org/10.4324/9781315457413">never learned</a> how to be elephants in their natural elements, as they were <a href="https://www.pugetsound.edu/sites/default/files/file/8342_Journal%20of%20Tourism%20%282009%29_0.pdf">separated from their herds</a> at an early age. So tourism may be vital to providing food, care and shelter to captive elephants for the rest of their lives and providing jobs for those who really need them. Because elephants can live beyond 60 years, this can be a large commitment. <h2>How to be an ethical tourist</h2> To protect elephants, tourists should check out reviews and photos from any venue they want to visit, and look for clues that animal welfare might be impacted, such as tourists allowed to feed, hold or ride captive wildlife animals. Look for healthy animals, which means doing research on what “healthy” animals of that species should look like. If a venue lists no-touch demonstrations – “unnatural” behaviors that don’t mimic what an elephant might do of their own accord, such as sitting on a ball or riding a bike, or other performances – remember that the behind-the-scenes training used to achieve these behaviors can be <a href="https://doi.org/10.21832/9781845415051-014">violent, traumatic or coercive</a>. Another way to help people and elephant is to to use small, local companies to book your adventures in your area of interest, rather than paying large, international tourism agencies. Look for locally owned hotels, and wait to book excursions until you arrive so you can use local service providers. Book homestay programs and attend cultural events led by community members; talk to tourists and locals you meet in the target town to get their opinions, and use local guides who provide wildlife viewing opportunities <a href="https://nepaldynamicecotours.com/">while maintaining distance from animals</a>. Or tourists can ask to visit <a href="https://www.americanhumane.org/press-release/global-humane-launches-humane-tourism-certification-program/">venues that are certified</a> by international humane animal organizations and that <a href="https://www.su4e.org/">do not allow contact</a> with wildlife. Or they can opt for guided hikes, canoe or kayak experiences, and other environmentally friendly options. While these suggestions will not guarantee that your excursion is animal-friendly, they will help decrease your impact on wildlife, support local families and encourage venues to stop using elephants as entertainment. Those are good first steps.<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/219792/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, Visiting Assistant Professor, Department of Biology, Project Dragonfly, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

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. 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. 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. 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. 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. "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. "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. "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. "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’.” 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. "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.” <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&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&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Chie Tchié Kelly-Kano (@kelly.chie)</a> </div> </blockquote> 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.

Despite numerous searches over the years, a DNA survey conducted in 2018 failed to provide any evidence of a plesiosaur or other large animals residing in the lake. Images: Instagram / Chie Kelly

If the world were coming to an end, what would be the most ethical way to rebuild humanity ‘off planet’?

<a href="https://theconversation.com/profiles/evie-kendal-734653">Evie Kendal</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Last week, scientists announced that for the first time on record, Antarctic ice has failed to “substantially recover” over winter, in a “once in 7.5-million-year event”. Climate change is the <a href="https://theconversation.com/antarctica-is-missing-a-chunk-of-sea-ice-bigger-than-greenland-whats-going-on-210665">most likely culprit</a>. Petra Heil, a sea ice physicist from the Australian Antarctic Division, <a href="https://www.abc.net.au/news/2023-07-24/antarctic-sea-ice-levels-nosedive-five-sigma-event/102635204">told the ABC</a> it could tip the world into a new state. “That would be quite concerning to the sustainability of human conditions on Earth, I suspect.” And in March, a senior United Nations disarmament official <a href="https://press.un.org/en/2023/sc15250.doc.htm">told the Security Council</a> the risk of nuclear weapons being used today is higher than at any time since the end of the Cold War. Both warnings speak to concerns about Earth’s security. Will our planet be able to support human life in the future? And if not, will humanity have another chance at survival in space? <h2>‘Billionauts’ and how to choose who goes</h2> Over the past few years, we’ve witnessed the rise of the “billionaut”. The ultra-wealthy are engaged in a <a href="https://theconversation.com/billionaire-space-race-the-ultimate-symbol-of-capitalisms-flawed-obsession-with-growth-164511">private space race</a> costing billions of dollars, while <a href="https://www.forbes.com/sites/oliverwilliams1/2021/12/21/billionaire-space-race-turns-into-a-publicity-disaster/?sh=79056f7e5e4d">regular citizens often condemn</a> the wasted resources and contribution to global carbon emissions. Space – described in the <a href="https://www.unoosa.org/oosa/en/ourwork/spacelaw/treaties/introouterspacetreaty.html">Outer Space Treaty</a> as being the “province of all mankind” – risks instead becoming the playground of the elite few, as they try to escape the consequences of environmental destruction. But if we have to select humans to send into space for a species survival mission, how do we choose who gets to go? In Montreal last month, the <a href="https://irg.space/irg-2023/">Interstellar Research Group</a> explored the question: how would you select a crew for the first interstellar mission? A panel led by <a href="https://www.erikanesvold.com/">Erika Nesvold</a>, a co-editor of the new book <a href="https://global.oup.com/academic/product/reclaiming-space-9780197604793?cc=au&lang=en&">Reclaiming Space</a>, discussed the perspectives of gender minorities, people with disabilities and First Nations groups regarding the ideal composition for an off-world crew. I was on the panel to discuss my contribution to the book, which explores how we can promote procreation in our new off-world society, without diminishing the reproductive liberty of survivors. <h2>The ultra-wealthy and reproductive slavery</h2> The first step in deciding how to allocate limited spaces on our “lifeboat” is identifying and rejecting options that are practically or ethically unacceptable. The first option I rejected was a user-pay system, whereby the wealthy can purchase a seat on the lifeboat. A 2022 Oxfam report showed the investments of just 125 billionaires collectively contribute 393 million tonnes of carbon dioxide equivalent per year: <a href="https://www.oxfam.org/en/press-releases/billionaire-emits-million-times-more-greenhouse-gases-average-person#:%7E:text=Recent%20data%20from%20Oxfam's%20research,%C2%B0C%20goal%20of%20the">a million times more</a> than the average for most global citizens. If the ultra-wealthy are the only ones to survive an environmental apocalypse, there’s a risk they would just create another one, on another planet. This would undermine the species survival project. The second option I rejected was allowing a reproductive slave class to develop, with some survivors compelled to populate the new community. This would disproportionately impact cis-gender women of reproductive capacity, demanding their gestational labour in exchange for a chance at survival. Neither a user-pay system nor reproductive slave labour would achieve the goal of “saving humanity” in any meaningful way. Many would argue preserving human values - including equality, reproductive liberty, and respect for diversity - is more important than saving human biology. If we lose what makes us unique as a species, that would be a kind of extinction anyway. But if we want humanity to survive, we still need to build our population in our new home. So what other options do we have? <h2>Reproduction and diversity</h2> How can we avoid discrimination on the basis of reproductive capacity – including age, sexuality, <a href="https://theconversation.com/infertility-through-the-ages-and-how-ivf-changed-the-way-we-think-about-it-87128">fertility status</a> or personal preference? We could avoid any questions about family planning when selecting our crew. This would align with <a href="https://www.seek.com.au/career-advice/article/illegal-interview-questions-what-employers-have-no-right-to-ask">equal opportunity policies</a> in other areas, like employment. But we would then have to hope enough candidates selected on other merits happen to be willing and able to procreate. Alternatively, we could reserve a certain number of places for those who agree to contribute to population growth. Fertility would then become an inherent job requirement. This might be similar to taking on a role as a <a href="https://theconversation.com/surrogacy-laws-why-a-global-approach-is-needed-to-stop-exploitation-of-women-98966">surrogate</a>, in which reproductive capacity is essential. But what if, after accepting such a position on the mission, someone changed their mind about wanting children? Would they be expected to provide some sort of compensation? Would they be vulnerable to retaliation? The more we focus on procreation, the less diversity we will preserve in the species as a whole – especially if we deliberately select against diverse sexualities, disabilities and older people. A lack of diversity would also threaten the long-term viability of the new society. For example, even if we exclude all physiologically or socially infertile people from the initial crew, these traits will reappear in future generations. The difference is: these children would be born into a less accepting community. Cooperation will be essential for the new human society – so promoting hostility would be counterproductive. So, what options are left? Using a random global sample to select travellers might alleviate concerns about equity and fairness. But the ability of a random sample to maximise our survival as a species would depend on how large the sample can be. A global sample would minimise bias. But there’s a risk it might yield a crew without doctors, engineers, farmers or other essential personnel. <h2>Random selection versus a points-based system</h2> The best balance between competing needs might be a stratified random sampling method, involving randomly selecting survivors from predetermined categories. Reproductive potential might be one category. Others might focus on other elements of practical usefulness or contribution to human diversity. Another option is a points-based system, whereby different skills and characteristics are ranked in terms of their desirability. In this system, an elderly person who speaks multiple languages may score higher than a physiologically fertile young person, due to their ability to substantially contribute to language preservation and education. This does not entirely eliminate the potential for discrimination, of course. Someone would need to decide which traits are most desirable and valuable to the new human society. However we determine our lifeboat candidates, it should be carefully considered. In our attempt to “save humanity”, we must avoid sacrificing the very things that make us human. <hr /> Evie Kendal is a contributor to <a href="https://global.oup.com/academic/product/reclaiming-space-9780197604793?cc=au&lang=en&">Reclaiming Space: Progressive and Multicultural Visions of Space Exploration</a> (Oxford University Press)<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/210647/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evie-kendal-734653">Evie Kendal</a>, Senior lecturer of health promotion, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Human remains found in search for missing teenager

Tasmanian Police have discovered human remains in their search for missing 14-year-old Shyanne-Lee Tatnell. After a huge ground and air search, the remains were found on a bush track at Nabowla, in the north-east of Tasmania. While police have yet to confirm the remains are those of the missing teen, they have notified Shyanne-Lee's parents of the discovery. Shyanne-Lee went missing almost three months ago on April 30th, and was last seen on a main road in Launceston. Northern District Commander Kate Chambers said a crime scene had been declared where the remains were found. "It is with a heavy heart that I can confirm that remains were located late this afternoon during our extensive search. While these have not yet been forensically confirmed, they are believed to be human remains," Chambers said. "We have been in regular contact with Shyanne-Lee's family throughout the investigative process, and have notified them about this latest development." "Our thoughts continue to be with them and Shyanne-Lee's loved ones during this difficult time." Police went on to confirm that no arrests have been made, but declared that the investigation into Shyanne-Lee's disappearance now likely had a “criminal element” as they are “following a specific line of inquiry". Tasmania Police, with the assistance of NSW Police, the Australian Federal Police, SES and community volunteers, launched what’s believed to be Northern Tasmania’s largest police operation on Wednesday in the search for clues as to Shyanne-Lee’s whereabouts.

10 reasons humans kill animals – and why we can’t avoid it

<a href="https://theconversation.com/profiles/benjamin-allen-100036">Benjamin Allen</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> As long as humans have existed, they’ve killed animals. But the necessity of some types of animal killing are now questioned by many. So can humans ever stop killing animals entirely? And if not, what’s the best way forward? <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062">New research</a> I led investigates these questions. My colleagues and I identified the ten main reasons why humans kill animals. We found the need for some types of animal killing is questionable, but several forms are inescapable – a necessary part of humanity’s involvement in a single, functioning, finite global food web. But the debate doesn’t end there. Even if humans must kill animals in some cases, they can modify their behaviours to improve the welfare of animals while they are alive, and to reduce an animal’s suffering when it is killed. Doing so may improve the lives of animals to a greater extent than efforts to eliminate human killing entirely. <h2>Why humans kill animals</h2> Critics of animal-killing come from a variety of perspectives. Some oppose it on <a href="http://refhub.elsevier.com/S0048-9697(23)03906-2/rf0005">moral grounds</a>. Others claim animals should have <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13494">rights equal</a> to humans, and say animal killing is a criminal act. Many people view any animal killing as <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13126">cruel</a>, regardless of whether the animal suffers. But as valid and important as these views might be, they largely fail to address why humans kill animals – and why in many cases, it can’t be avoided. Our research sought to shed light on this. We focus our discussion on vertebrate animals which are almost universally recognised as “sentient” (or able to perceive and feel things). We identified ten main reasons humans kill animals: 1. Wild harvest or food acquisition: such as killing wild animals for meat 2. Human health and safety: such as reactively killing an animal when it attacks you 3. Agriculture and aquaculture: such as killing that occurs in the global meat industries, or killing required to produce crops 4. Urbanisation and industrialisation: such as clearing bushland to build homes 5. Wildlife control: such as programs that eradicate introduced animals to stop them killing native ones 6. Threatened species conservation: such as unintentionally killing animals when relocating them 7. Recreation, sport or entertainment: such as trophy hunting or bull fighting, and animal killing required to feed domestic pets 8. Mercy or compassion: such as euthanasing an animal hit by a car 9. Cultural and religious practice: such as animal sacrifice during the Islamic celebration of <a href="https://www.theguardian.com/world/2023/jul/01/sydney-muslims-take-eid-al-adha-livestock-sacrifice-into-their-own-hands">Eid al-Adha</a>, or those associated with the <a href="https://www.jstor.org/stable/1594756">Yoruba</a> religion of West Africa 10. Research, education and testing: such as the laboratory use of rodents or primates. <h2>Understanding human killing behaviour</h2> So how best should we understand the above types of animal killing? Our research considers them in ecological terms – as behaviours consistent with our predatory and competitive roles in the global food web. Such behaviours are intended to improve human prospects for acquiring food or to protect and enhance life. These are innate life objectives for any sentient animal. Maintenance of all life on Earth requires obtaining, using, disposing of and recycling chemical elements. Ecosystems can be thought of as a “battleground” for these elements. <a href="https://theconversation.com/peter-singers-fresh-take-on-animal-liberation-a-book-that-changed-the-world-but-not-enough-205830">Some people argue</a> that directly killing animals is unacceptable, or that adopting certain lifestyles or diets, such as veganism, can eliminate or greatly reduce animal killing. But in our view, achieving a no-killing lifestyle is a physical and ecological impossibility. For instance, most plant foods come from crops grown on land where animals have been <a href="https://www.mdpi.com/2076-2615/11/5/1225">killed or displaced</a>. And while an animal-free diet for humans might temporarily reduce the number of animals killed, this won’t last forever. As human populations continue to grow, more land will eventually be needed to meet their food requirements. At that point, humans will have to directly or indirectly kill animals again or risk dying themselves. Humans also need space to live, which <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb1045">results in</a> animal killing when habitat is razed. Of course, in rare cases an individual human may live without killing animals directly. Perhaps they live in a cave in the forest, and get sustenance from wild berries and mushrooms. But that human still lives inside the food web, and is competing against other animals for finite resources. In these cases, other animals may suffer and die because the human’s use of berries and caves leaves less food and space for them. Even if that human could do no harm at all to any animal, it’s still impossible for societies at large to live in this way. Some forms of animal killing are certainly not essential for human existence. Good examples are recreational hunting, euthanasia or keeping pets (which requires killing animals to feed them). And we certainly do not condone direct human participation in all forms of animal killing. It’s also important to note that in many cases, current levels of animal killing are <a href="https://www.opsociety.org/stop-unsustainable-fishing/">unsustainable</a>. Human populations have increased to the point where animals must be killed on enormous scales to feed, house and protect ourselves. If this continues, animal <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb0905">populations</a> will <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb0910">crash</a> – and with them, human populations. Nevertheless, we maintain that the overall necessity of animal killing is an unavoidable reality for humanity as a whole. A variety of direct and indirect forms of animal killing will undoubtedly remain an ongoing human endeavour. <h2>Taking responsibility</h2> So what are the implications of all this? We hope our research leads to a constructive dialogue, which starts with accepting that human existence on Earth is dependent on animal killing. It should then focus on the nuances of animal welfare and sustainability. Humans are the only known animals with an ethical or moral conscience. That means we have <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb0650">a responsibility</a> to assume a stewardship role over all other animals, to resolve negative interactions between them as best as possible, and to ensure good welfare for as many animals as we can. Directing our attention in this way is likely to improve the lives of animals to a greater extent than trying to prevent humans from killing animals altogether – efforts my colleagues and I believe will ultimately be in vain.<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/209218/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/benjamin-allen-100036">Benjamin Allen</a>, Wildlife ecologist, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Possibly carcinogenic to humans": WHO's dire warning over common ingredient

The World Health Organisation (WHO) has called for one of the world’s most popular artificial sweeteners to be declared a possible carcinogen. The push will be led by the WHO’s research team for the International Agency for Research on Cancer (IARC), pitting it against the food industry and regulators. The sweetener, known as Aspartame, is used in products from Coca-Cola diet drinks, such as Diet Coke and Coke Zero, to Mars’ Extra chewing gum and some Snapple drinks. Later this month, the IARC will list Aspartame for the first time as “possibly carcinogenic to humans” The ruling from the IARC has assessed whether the sweetener is hazardous to humans or not, although it does not stipulate how much of the product a person can safely consume. This advice for individual consumers comes from a different organisation, known as JECFA (the Joint WHO and Food and Agriculture Organisation’s Expert Committee on Food Additives), who make consumption guidelines alongside national regulators. Despite the claims from the WHO, since as early as 1981 JECFA has said aspartame is safe to consume within accepted daily limits. An adult weighing 60kg would have to drink between 12 and 36 cans of diet soft drink, depending on the amount of aspartame in the beverage, every day to be at risk. Its view has been widely shared by national regulators, including in the United States and Europe. These conflicting reports have angered some regulators and consumers alike, with Japan’s Ministry of Health, Labour and Welfare official Nozomi Tomita writing to the WHO, “kindly asking both bodies to coordinate their efforts in reviewing aspartame to avoid any confusion or concerns among the public.” Image credits: Getty Images

Human remains found in search for missing actor

Californian hikers have discovered human remains in the wilderness area where actor Julian Sands disappeared more than five months ago, according to authorities. Officials have not yet identified the victim. The remains were transported to the coroner’s office for confirmation, which is expected to be completed next week, The New York Post reported. Sands was reported missing on January 13 after he failed to return from a hiking trip in Mount Baldy, located about 72 kilometres east of Los Angeles. The search – consisting of 80 volunteers and officials – resumed on June 12 after a temporary suspension. Police have conducted eight ground and air searches since the actor's disappearance on the mountain. “Despite the recent warmer weather, portions of the mountain remain inaccessible due to extreme alpine conditions. Multiple areas include steep terrain and ravines, which still have 10-plus feet [about 16 metres] of ice and snow,” San Bernardino County Sheriff’s Office said. Sands’ family spoke publicly for the first time since he vanished, releasing a statement on June 23 to express their gratitude for the ongoing search and rescue efforts. “We are deeply grateful to the search teams and co-ordinators who have worked tirelessly to find Julian,” the family said. “We continue to hold Julian in our hearts, with bright memories of him as a wonderful father, husband, explorer, lover of the natural world and the arts, and as an original and collaborative performer.” Sands is known for starring in films such as Arachnophobia, A Room with a View, Warlock and Leaving Las Vegas. Mt. Baldy is renowned for being one of the most dangerous peaks to climb in California. According to the Los Angeles Times, six people have died with crews conducting over 100 searches as daredevils and avid hikers alike are drawn to the daunting challenge of the more-than-16,000 metre climb. In January, officials found hiker Jin Chung, 75, who had become lost on Mount Baldy and was hospitalised with a leg injury and other weather-related injuries. Before Chung’s brief disappearance, a mother of four fell more than 500 to 700 feet to her death. Crystal Paula Gonzalez, renowned as a “hiking queen”, slipped on the steep icy hillside and later died from her injuries, officials reported. Image credit: Facebook / Getty

Three Aussie regions set to be unliveable

Three major economic centres are set to become uninhabitable by the end of the century as global temperatures are on track to warm by 2.7C. It is predicted that Broome, Darwin and Port Hedland in WA are to be pushed outside the “human climate niche”, referring to the temperature and humidity conditions in which humans can survive. The destinations are just three of the many northwestern sections of Australia facing “niche displacement” in the next 70 years. New research by The University of Exeter, published in the science journal Nature Sustainability in May 2023, calculates the human cost of climate inaction based on current insufficient policies and government inaction. According to the report, two million people will be living with unprecedented mean average temperatures (MAT) above 29C. MAT >29C is the point at which wellbeing scientifically declines, labour productivity and cognitive ability shrinks, negative pregnancy outcomes are emancipated and mortality rates soar. The report calculates that twenty per cent of Australia, around 374,977 Aussies, will be negatively impacted by the 2.7C temperature increase. Those Australians would join a third of the world’s population, including Africa, South America, and South-East Asia. A 3C warmer temperature in Darwin would mean that for 265 days of the year, temperatures would reach above 35C. At 40C, humidity soars and temperatures become lethal, the Australian Academy of Science reports. The University of Exeter report also explained the effects of a “wet-bulb temperature” where temperature and humidity are combined. In temperatures above 28C (WBT) body struggles to cool itself by sweating, and fails to do so in temperatures above 35C (WBT), which can be fatal. By limiting global warming to 1.5C, which is the goal of the Paris Agreement, 80 per cent of those at risk of rising temperatures would remain in their climate niche. However, scientists warn that a 1.5C will still cause severe and irreversible effects on people, wildlife and ecosystems. Global warming currently sits at 1.2C, but new research from The World Meteorological Organisation suggests there is a 66 per cent chance at least one year in the next five will breach the 1.5C threshold. “Despite increased pledges and targets to tackle climate change, current policies still leave the world on course for about 2.7C end-of-century global warming,” The University of Exeter report said. “These results highlight the need for more decisive policy action to limit the human costs and inequities of climate change.” The report also found the impacts of rising temperatures will not be felt equally, as estimates of the human cost of climate change “tend to be expressed in monetary terms”. “(Estimates) tends to recognise impacts on the rich more than those on the poor (because the rich have more money to lose) and tend to value those living now over those living in the future (because future damages are subject to economic discounting),” the report said. “From an equity standpoint, this is unethical — when life or health are at stake, all people should be considered equal, whether rich or poor, alive or yet to be born.” Image credit: Shutterstock

Will AI ever reach human-level intelligence? We asked 5 experts

Artificial intelligence has changed form in recent years. What started in the public eye as a burgeoning field with promising (yet largely benign) applications, has snowballed into a <a href="https://www.grandviewresearch.com/industry-analysis/artificial-intelligence-ai-market">more than US$100 billion</a> industry where the heavy hitters – Microsoft, Google and OpenAI, to name a few – seem <a href="https://theconversation.com/bard-bing-and-baidu-how-big-techs-ai-race-will-transform-search-and-all-of-computing-199501">intent on out-competing</a> one another. The result has been increasingly sophisticated large language models, often <a href="https://theconversation.com/everyones-having-a-field-day-with-chatgpt-but-nobody-knows-how-it-actually-works-196378">released in haste</a> and without adequate testing and oversight. These models can do much of what a human can, and in many cases do it better. They can beat us at <a href="https://theconversation.com/an-ai-named-cicero-can-beat-humans-in-diplomacy-a-complex-alliance-building-game-heres-why-thats-a-big-deal-195208">advanced strategy games</a>, generate <a href="https://theconversation.com/ai-art-is-everywhere-right-now-even-experts-dont-know-what-it-will-mean-189800">incredible art</a>, <a href="https://theconversation.com/breast-cancer-diagnosis-by-ai-now-as-good-as-human-experts-115487">diagnose cancers</a> and compose music. There’s no doubt AI systems appear to be “intelligent” to some extent. But could they ever be as intelligent as humans? There’s a term for this: artificial general intelligence (AGI). Although it’s a broad concept, for simplicity you can think of AGI as the point at which AI acquires human-like generalised cognitive capabilities. In other words, it’s the point where AI can tackle any intellectual task a human can. AGI isn’t here yet; current AI models are held back by a lack of certain human traits such as true creativity and emotional awareness. We asked five experts if they think AI will ever reach AGI, and five out of five said yes. But there are subtle differences in how they approach the question. From their responses, more questions emerge. When might we achieve AGI? Will it go on to surpass humans? And what constitutes “intelligence”, anyway? Here are their detailed responses. Paul Formosa: AI and Philosophy of Technology AI has already achieved and surpassed human intelligence in many tasks. It can beat us at strategy games such as Go, chess, StarCraft and Diplomacy, outperform us on many <a href="https://www.nature.com/articles/s41467-022-34591-0" target="_blank" rel="noopener">language performance</a>benchmarks, and write <a href="https://www.theatlantic.com/technology/archive/2022/12/chatgpt-ai-writing-college-student-essays/672371/" target="_blank" rel="noopener">passable undergraduate</a> university essays. Of course, it can also make things up, or “hallucinate”, and get things wrong – but so can humans (although not in the same ways). Given a long enough timescale, it seems likely AI will achieve AGI, or “human-level intelligence”. That is, it will have achieved proficiency across enough of the interconnected domains of intelligence humans possess. Still, some may worry that – despite AI achievements so far – AI will not really be “intelligent” because it doesn’t (or can’t) understand what it’s doing, since it isn’t conscious. However, the rise of AI suggests we can have intelligence without consciousness, because intelligence can be understood in functional terms. An intelligent entity can do intelligent things such as learn, reason, write essays, or use tools. The AIs we create may never have consciousness, but they are increasingly able to do intelligent things. In some cases, they already do them at a level beyond us, which is a trend that will likely continue. Christina Maher: Computational Neuroscience and Biomedical Engineering AI will achieve human-level intelligence, but perhaps not anytime soon. Human-level intelligence allows us to reason, solve problems and make decisions. It requires many cognitive abilities including adaptability, social intelligence and learning from experience. AI already ticks many of these boxes. What’s left is for AI models to learn inherent human traits such as critical reasoning, and understanding what emotion is and which events might prompt it. As humans, we learn and experience these traits from the moment we’re born. Our first experience of “happiness” is too early for us to even remember. We also learn critical reasoning and emotional regulation throughout childhood, and develop a sense of our “emotions” as we interact with and experience the world around us. Importantly, it can take many years for the human brain to develop such intelligence. AI hasn’t acquired these capabilities yet. But if humans can learn these traits, AI probably can too – and maybe at an even faster rate. We are still discovering how AI models should be built, trained, and interacted with in order to develop such traits in them. Really, the big question is not if AI will achieve human-level intelligence, but when – and how. Seyedali Mirjalili: AI and Swarm Intelligence I believe AI will surpass human intelligence. Why? The past offers insights we can't ignore. A lot of people believed tasks such as playing computer games, image recognition and content creation (among others) could only be done by humans – but technological advancement proved otherwise. Today the rapid advancement and adoption of AI algorithms, in conjunction with an abundance of data and computational resources, has led to a level of intelligence and automation previously unimaginable. If we follow the same trajectory, having more generalised AI is no longer a possibility, but a certainty of the future. It is just a matter of time. AI has advanced significantly, but not yet in tasks requiring intuition, empathy and creativity, for example. But breakthroughs in algorithms will allow this. Moreover, once AI systems achieve such human-like cognitive abilities, there will be a snowball effect and AI systems will be able to improve themselves with minimal to no human involvement. This kind of “automation of intelligence” will profoundly change the world. Artificial general intelligence remains a significant challenge, and there are ethical and societal implications that must be addressed very carefully as we continue to advance towards it. Dana Rezazadegan: AI and Data Science Yes, AI is going to get as smart as humans in many ways – but exactly how smart it gets will be decided largely by advancements in <a href="https://thequantuminsider.com/2020/01/23/four-ways-quantum-computing-will-change-artificial-intelligence-forever/" target="_blank" rel="noopener">quantum computing</a>. Human intelligence isn’t as simple as knowing facts. It has several aspects such as creativity, emotional intelligence and intuition, which current AI models can mimic, but can’t match. That said, AI has advanced massively and this trend will continue. Current models are limited by relatively small and biased training datasets, as well as limited computational power. The emergence of quantum computing will transform AI’s capabilities. With quantum-enhanced AI, we’ll be able to feed AI models multiple massive datasets that are comparable to humans’ natural multi-modal data collection achieved through interacting with the world. These models will be able to maintain fast and accurate analyses. Having an advanced version of continual learning should lead to the development of highly sophisticated AI systems which, after a certain point, will be able to improve themselves without human input. As such, AI algorithms running on stable quantum computers have a high chance of reaching something similar to generalised human intelligence – even if they don’t necessarily match every aspect of human intelligence as we know it. Marcel Scharth: Machine Learning and AI Alignment I think it’s likely AGI will one day become a reality, although the timeline remains highly uncertain. If AGI is developed, then surpassing human-level intelligence seems inevitable. Humans themselves are proof that highly flexible and adaptable intelligence is allowed by the laws of physics. There’s no <a href="https://en.wikipedia.org/wiki/Church%E2%80%93Turing_thesis" target="_blank" rel="noopener">fundamental reason</a> we should believe that machines are, in principle, incapable of performing the computations necessary to achieve human-like problem solving abilities. Furthermore, AI has <a href="https://philarchive.org/rec/SOTAOA" target="_blank" rel="noopener">distinct advantages</a> over humans, such as better speed and memory capacity, fewer physical constraints, and the potential for more rationality and recursive self-improvement. As computational power grows, AI systems will eventually surpass the human brain’s computational capacity. Our primary challenge then is to gain a better understanding of intelligence itself, and knowledge on how to build AGI. Present-day AI systems have many limitations and are nowhere near being able to master the different domains that would characterise AGI. The path to AGI will likely require unpredictable breakthroughs and innovations. The median predicted date for AGI on <a href="https://www.metaculus.com/questions/5121/date-of-artificial-general-intelligence/" target="_blank" rel="noopener">Metaculus</a>, a well-regarded forecasting platform, is 2032. To me, this seems too optimistic. A 2022 <a href="https://aiimpacts.org/2022-expert-survey-on-progress-in-ai/" target="_blank" rel="noopener">expert survey</a> estimated a 50% chance of us achieving human-level AI by 2059. I find this plausible.

Humans are still hunting for aliens. Here’s how astronomers are looking for life beyond Earth

We have long been fascinated with the idea of alien life. The earliest written record presenting the idea of “aliens” is seen in the satiric work of Assyrian writer <a href="https://blogs.scientificamerican.com/life-unbounded/the-first-alien/">Lucian of Samosata</a> dated to 200 AD. In one novel, Lucian <a href="https://www.yorku.ca/inpar/lucian_true_tale.pdf">writes of a journey to the Moon</a> and the bizarre life he imagines living there – everything from three-headed vultures to fleas the size of elephants. Now, 2,000 years later, we still write stories of epic adventures beyond Earth to meet otherworldly beings (<a href="https://www.britannica.com/topic/The-Hitchhikers-Guide-to-the-Galaxy-novel-by-Adams">Hitchhiker’s Guide</a>, anyone?). Stories like these entertain and inspire, and we are forever trying to find out if science fiction will become science fact. <h2>Not all alien life is the same</h2> When looking for life beyond Earth, we are faced with two possibilities. We might find basic microbial life hiding somewhere in our Solar System; or we will identify signals from intelligent life somewhere far away. <div data-id="17"> </div> Unlike in <a href="https://www.britannica.com/topic/Star-Wars-film-series">Star Wars</a>, we’re not talking far, far away in another galaxy, but rather around other nearby stars. It is this second possibility which really excites me, and should excite you too. A detection of intelligent life would fundamentally change how we see ourselves in the Universe. In the last 80 years, programs dedicated to the search for extraterrestrial intelligence (SETI) have worked tirelessly searching for cosmic “hellos” in the form of radio signals. The reason we think any intelligent life would communicate via radio waves is due to the waves’ ability to travel vast distances through space, rarely interacting with the dust and gas in between stars. If anything out there is trying to communicate, it’s a pretty fair bet they would do it through radio waves. <h2>Listening to the stars</h2> One of the most exciting searches to date is <a href="https://breakthroughinitiatives.org/initiative/1">Breakthrough Listen</a>, the largest scientific research program dedicated to looking for evidence of intelligent life beyond Earth. This is one of many projects funded by US-based Israeli entrepreneurs Julia and Yuri Milner, with some serious dollars attached. Over a ten-year period a total amount of <a href="https://breakthroughinitiatives.org/initiative/1">US$100 million</a> will be invested in this effort, and they have a mighty big task at hand. Breakthrough Listen is currently targeting the closest one million stars in the hope of identifying any unnatural, alien-made radio signals. Using telescopes around the globe, from the 64-metre Murriyang Dish (Parkes) here in Australia, to the 64-antenna MeerKAT array in South Africa, the search is one of epic proportions. But it isn’t the only one. Hiding away in the Cascade Mountains north of San Francisco sits the <a href="https://www.seti.org/ata">Allen Telescope Array</a>, the first radio telescope built from the ground up specifically for SETI use. This unique facility is another exciting project, able to search for signals every day of the year. This project is currently upgrading the hardware and software on the original dish, including the ability to target several stars at once. This is a part of the non-profit research organisation, the SETI Institute. <h2>Space lasers!</h2> The SETI Institute is also looking for signals that would be best explained as “space lasers”. Some astronomers hypothesise that intelligent beings might use massive lasers to communicate or even to propel spacecraft. This is because even here on Earth we’re investigating <a href="https://www.nasa.gov/feature/goddard/2022/the-future-of-laser-communications/">laser communication</a> and laser-propelled <a href="https://www.insidescience.org/news/new-light-sail-design-would-use-laser-beam-ride-space">light sails</a>. To search for these mysterious flashes in the night sky, we need speciality instruments in locations around the globe, which are currently being developed and deployed. This is a research area I’m excited to watch progress and eagerly await results. As of writing this article, sadly no alien laser signals have been found yet. <h2>Out there, somewhere</h2> It’s always interesting to ponder who or what might be living out in the Universe, but there is one problem we must overcome to meet or communicate with aliens. It’s the speed of light. Everything we rely on to communicate via space requires light, and it can only travel so fast. This is where my optimism for finding intelligent life begins to fade. The Universe is big – really big. To put it in perspective, humans started using radio waves to communicate across large distances in 1901. That <a href="https://ethw.org/Milestones:Reception_of_Transatlantic_Radio_Signals,_1901">first transatlantic signal</a> has only travelled 122 light years, reaching just 0.0000015% of the stars in our Milky Way. Did your optimism just fade too? That is okay, because here is the wonderful thing… we don’t have to find life to know it is out there, somewhere. When we consider the <a href="https://theconversation.com/how-many-stars-are-there-in-space-165370">trillions of galaxies</a>, septillion of stars, and likely many more planets just in the observable Universe, it feels near impossible that we are alone. We can’t fully constrain the parameters we need to estimate how many other lifeforms might be out there, as famously proposed by Frank Drake, but using our best estimates and <a href="https://www.cambridge.org/core/journals/international-journal-of-astrobiology/article/numerical-testbed-for-hypotheses-of-extraterrestrial-life-and-intelligence/0C97E7803EEB69323C3728F02BA31AFA">simulations</a> the current best answer to this is tens of thousands of possible civilisations out there. The Universe <a href="https://theconversation.com/is-space-infinite-we-asked-5-experts-165742">might even be infinite</a>, but that is too much for my brain to comprehend on a weekday. <h2>Don’t forget the tiny aliens</h2> So, despite keenly listening for signals, we might not find intelligent life in our lifetimes. But there is hope for aliens yet. The ones hiding in plain sight, on the planetary bodies of our Solar System. In the coming decades we’ll explore the moons of Jupiter and Saturn like never before, with missions hunting to find traces of basic life. Mars will continue to be explored – eventually by humans – which could allow us to uncover and retrieve samples from new and unexplored regions. Even if our future aliens are only tiny microbes, it would still be nice to know we have company in this Universe.

We can pretty accurately tell when a human or dog is happy, but not so much with aggression

Humans are terrible at understanding aggressive characteristics in dogs — and unfortunately, in other humans. Being able to correctly interpret social interactions is an important skill that allows humans to react appropriately in different situations. But, research from the Dog Studies Research group at the Max Planck Institute for Geoanthropology in Germany shows while we’re generally clued in to distinguishing the nature of social interactions between children, dogs, and monkeys, we suck at identifying negative behaviour in dogs and humans. Researchers presented 96 adults with short video clips of aggressive, neutral, and playful interactions between two individuals in three different species: human children, dogs, and macaques. The clips included clues, such as body postures and facial expressions, but ended before the interaction took place. Half the study participants were asked to categorise the interaction as aggressive, neutral, or playful, while the other half were asked to predict the outcome from three sentences prepared by the experimenters describing the three possible outcomes. The researchers found that people performed better than chance for both tasks, even without prior experiences with the non-human species. They selected the correct choice of the three outcomes in 50–80% of interactions and were most accurate in categorising playful interactions, which they correctly identified 70% of the time. This wasn’t the case for predicting aggressive outcomes in humans and in pooches in particular. Participants rated aggressive contexts among dogs at chance level, and predicted outcomes below chance level. “It is possible that we are biased to assume good intentions from other humans and from ‘man’s best friend’,” says first author Dr Theresa Epperlein the DogStudies Research group in the Max Planck Institute for Geoanthropology, Germany. “Perhaps this bias prevents us from recognising aggressive situations in these species.” “Our results underscore the fact that social interactions can often be ambiguous and suggest that accurately predicting outcomes may be more advantageous than categorising emotional contexts,” adds senior author Dr Juliane Bräuer, DogStudies Research Group Leader. The research has been <a href="https://doi.org/10.1371/journal.pone.0277783" target="_blank" rel="noreferrer noopener">published</a> in the journal PLOS ONE.  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=227826&title=We+can+pretty+accurately+tell+when+a+human+or+dog+is+happy%2C+but+not+so+much+with+aggression" width="1" height="1" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" />  <div id="contributors"> <a href="https://cosmosmagazine.com/people/human-dogs-aggressive/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Imma Perfetto.

‘This case has made legal history’: young Australians just won a human rights case against an enormous coal mine

In a <a href="https://www.sclqld.org.au/caselaw/QLC/2022/21" target="_blank" rel="noopener">historic ruling</a>, a Queensland court has said the massive Clive Palmer-owned Galilee Basin coal project should not go ahead because of its contribution to climate change, its environmental impacts, and because it would erode human rights. <a href="https://theconversation.com/these-young-queenslanders-are-taking-on-clive-palmers-coal-company-and-making-history-for-human-rights-138732" target="_blank" rel="noopener">The case</a> was mounted in 2020 by a First Nations-led group of young people aged 13 to 30 called Youth Verdict. It was the first time human rights arguments were used in a climate change case in Australia. The link between human rights and climate change is being increasingly recognised overseas. In September this year, for example, a United Nations <a href="https://theconversation.com/australia-violated-the-rights-of-torres-strait-islanders-by-failing-to-act-on-climate-change-the-un-says-heres-what-that-means-191329" target="_blank" rel="noopener">committee decided</a> that by failing to adequately address the climate crisis, Australia’s Coalition government violated the human rights of Torres Strait Islanders. Youth Verdict’s success today builds on this momentum. It heralds a new era for climate change cases in Australia by youth activists, who have been frustrated with the absence of meaningful federal government policy. <h2>1.58 billion tonnes of emissions</h2> The Waratah Coal mine operation <a href="https://www.sbs.com.au/nitv/article/the-first-nations-group-fighting-clive-palmers-mining-project/6xbg2e81w" target="_blank" rel="noopener">proposes to</a> extract up to 40 million tonnes of coal from the Galilee Basin each year, over the next 25 years. This would <a href="https://www.theguardian.com/australia-news/2022/nov/25/court-finds-clive-palmers-queensland-coalmine-will-harm-future-generations-in-landmark-climate-ruling?CMP=share_btn_tw" target="_blank" rel="noopener">produce</a> 1.58 billion tonnes of carbon emissions, and is <a href="https://www.abc.net.au/news/2019-12-05/galilee-basin-farmers-object-to-palmer-mine/11764540" target="_blank" rel="noopener">four times more</a> coal extraction than Adani’s operation. While the project has already received approval at the federal government level, it also needs a state government mining lease and environmental authority to go ahead. Today, Queensland land court President Fleur Kingham has recommended to the state government that both entitlements be refused. In making this recommendation, Kingham reflected on how the global landscape has changed since the Paris Agreement in 2015, <a href="https://theconversation.com/carmichael-mine-jumps-another-legal-hurdle-but-litigants-are-making-headway-69423" target="_blank" rel="noopener">and since the last major challenge</a> to a mine in Queensland in 2016: Adani’s Carmichael mine. She drew a clear link between the mining of this coal, its ultimate burning by a third party overseas, and the project’s material contribution to global emissions. She concluded that the project poses “unacceptable” climate change risks to people and property in Queensland. The Queensland <a href="https://www.legislation.qld.gov.au/view/html/asmade/act-2019-005" target="_blank" rel="noopener">Human Rights Act</a> requires a decision-maker to weigh up whether there is any justifiable reason for limiting a human right, which could incorporate a consideration of new jobs. Kingham decided the importance of preserving the human rights outweighed the potential A$2.5 billion of economic benefits of the proposed mine. From a legal perspective, I believe there are four reasons in particular this case is so significant. <h2>1. Rejecting an entrenched assumption</h2> A major barrier to climate change litigation in Queensland has been the “<a href="https://theconversation.com/landmark-rocky-hill-ruling-could-pave-the-way-for-more-courts-to-choose-climate-over-coal-111533" target="_blank" rel="noopener">market substitution assumption</a>”, also known as the “perfect substitution argument”. This is the assertion that a particular mine’s contribution to climate change is net zero, because if that mine doesn’t supply coal, then another will. Kingham rejected this argument. She noted that the economic benefits of the proposed project are uncertain with long-term <a href="https://www.iea.org/news/world-energy-outlook-2022-shows-the-global-energy-crisis-can-be-a-historic-turning-point-towards-a-cleaner-and-more-secure-future" target="_blank" rel="noopener">global demand</a> for thermal coal set to decline. She observed that there’s a real prospect the mine might not be viable for its projected life, rebutting the market substitution assumption. This is an enormous victory for environmental litigants as this was a previously entrenched argument in Australia’s legal system and policy debate. <h2>2. Evidence from First Nations people</h2> <a href="https://www.sbs.com.au/nitv/article/on-country-evidence-in-landmark-case-against-clive-palmers-coal-project/6eiueghuy" target="_blank" rel="noopener">It was also the first time</a> the court took on-Country evidence from First Nations people in accordance with their traditional protocols. Kingham and legal counsel travelled to Gimuy (around Cairns) and Traditional Owners showed how climate change has directly harmed their Country. As Youth Verdict co-director and First Nations lead Murrawah Johnson <a href="https://www.edo.org.au/2022/04/20/landmark-hearing-into-clive-palmers-galilee-coal-project-legal-challenge-begins/" target="_blank" rel="noopener">put it</a>: We are taking this case against Clive Palmer’s Waratah Coal mine because climate change threatens all of our futures. For First Nations peoples, climate change is taking away our connection to Country and robbing us of our cultures which are grounded in our relationship to our homelands. Climate change will prevent us from educating our young people in their responsibilities to protect Country and deny them their birth rights to their cultures, law, lands and waters. This decision reflects the court’s deep engagement with First Nations’ arguments, in considering the impacts of climate change on First Nations people. <h2>3. The human rights implications</h2> In yet another Australian first, the court heard submissions on the human rights implications of the mine. The Land Court of Queensland has a unique jurisdiction in these matters, because it makes a recommendation, rather than a final judgment. This recommendation must be taken into account by the final decision-makers – in this case, the Queensland resources minister, and the state Department of Environment and Science. <a href="https://archive.sclqld.org.au/qjudgment/2020/QLC20-033.pdf" target="_blank" rel="noopener">In an earlier proceeding</a>, Kingham found the land court itself is subject to obligations under Queensland’s Human Rights Act. This means she must properly consider whether a decision to approve the mine would limit human rights and if so, whether limits to those human rights can be demonstrably justified. Kingham found approving the mine would contribute to climate change impacts, which would limit: <ul> <li>the right to life</li> <li>the cultural rights of First Nations peoples</li> <li>the rights of children</li> <li>the right to property and to privacy and home</li> <li>the right to enjoy human rights equally.</li> </ul> Internationally, there are <a href="https://theconversation.com/mass-starvation-extinctions-disasters-the-new-ipcc-reports-grim-predictions-and-why-adaptation-efforts-are-falling-behind-176693" target="_blank" rel="noopener">clear links</a> made between climate change and human rights. For example, climate change is worsening heatwaves, risking a greater number of <a href="https://theconversation.com/how-hot-is-too-hot-for-the-human-body-our-lab-found-heat-humidity-gets-dangerous-faster-than-many-people-realize-185593" target="_blank" rel="noopener">deaths</a>, thereby affecting the right to life. <h2>4. A victory for a nature refuge</h2> Kingham also considered the environmental impacts of the proposed mine on the <a href="https://bimblebox.org/about/" target="_blank" rel="noopener">Bimblebox Nature Refuge</a> – 8,000 hectares semi-arid woodland, home to a recorded 176 bird species, in the Galilee Basin. She deemed these impacts unacceptable, as “the ecological values of Bimblebox [could be] seriously and possibly irreversibly damaged”. She also observed that the costs of climate change to people in Queensland have not been fully accounted for, nor have the costs of mining on the Bimblebox Nature Refuge. Further, she found the mine would violate Bimblebox Alliance’s right to family and home. <h2>Making history</h2> This case has made legal history. It is the first time a Queensland court has recommended refusal of a coal mine on climate change grounds, and the first case linking human rights and climate change in Australia. As Kingham concluded: <blockquote> Approving the application would risk disproportionate burdens for future generations, which does not give effect to the goal of intergenerational equity. </blockquote> The future of the project remains unclear. But in a year marked by climate-related disasters, the land court’s decision offers a ray of hope that Queensland may start to leave coal in the ground.

Drop that bass (below the level of human hearing) to get bodies on the dance floor moving

People dance nearly 12% more when music includes very low frequency bass but researchers have found that it may be the sounds we don’t hear that gets our toes tapping. This is interesting news for those who’ve had an experience at a party, celebration or club when the music’s groove just isn’t making your body move and who might be tempted to reach for the nearest beverage to lubricate our joints. But maybe there’s a solution which is more subtle – and less liable to cause headaches the next day… It seems, as Meghan Trainor correctly observed in 2014, that it really is “All About That Bass.” Now, it is no revelation that bass-driven music is good for a boogie. Trainor certainly wasn’t the first to discover this critical component of the rhythm section. Researchers from Canada and Germany turned a live electronic music concert into a lab study, to find out how different qualities of music influence the body. Their results are <a href="https://doi.org/10.1016/j.cub.2022.09.035%20" target="_blank" rel="noreferrer noopener">published</a> in Current Biology. The researchers introduced over speakers levels of bass below human hearing levels. This super low pitch infrasound is made up of wavelengths of sound too long for our ears to pick up. Infrasound is common in whale song and other parts of the animal and natural world. Monitoring the crowd’s movements, the scientists found that people danced 11.8% more when the very low frequency bass was present. “I’m trained as a drummer, and most of my research career has been focused on the rhythmic aspects of music and how they make us move,” says first author Daniel Cameron, a neuroscientist from Canada’s McMaster University. “Music is a biological curiosity – it doesn’t reproduce us, it doesn’t feed us, and it doesn’t shelter us, so why do humans like it and why do they like to move to it?” Cameron and colleagues treated participants in the study to a 45-minute live set by electronic musical duo Orphx at LIVELab, a research theatre at the University. Donning motion-sensing headbands, the concert-goers’ dance moves were monitored. They were also asked to fill out survey forms before and after to ensure they didn’t detect the infrasound, to measure their enjoyment, and examine how the music felt physically. Turning the ultra-low bass playing speakers on and off every two minutes, the researchers found movement increased by 12% when the speakers were on. Vibrations experienced through touch and interactions between the inner ear and brain are closely linked to the motor system. The researchers theorise that there is a neurological link between these physiological processes and music. They believe that our anatomy can pick up on low frequencies, affecting our perception of “groove”, spontaneous movement and rhythm. Cameron suggests that the super-low frequencies may influence the vestibular system which controls body position and movement through the inner ear. “Very low frequencies may also affect vestibular sensitivity, adding to people’s experience of movement. Nailing down the brain mechanisms involved will require looking the effects of low frequencies on the vestibular, tactile, and auditory pathways,” says Cameron.

Evidence that human evolution driven by major environmental pressures discovered

The genes of ancient humans might have changed substantially due to environmental pressures and change, say an international team of researchers. A widely held belief related to human evolution is that our ancient ancestors’ ability to fashion tools, shelter, and use advanced communication skills may have helped to shield them from large environmental impacts such as changing climate, disease and exposure to other events affecting mortality. But research led out of Australian Centre for Ancient DNA at the University of Adelaide suggests that beneficial genes may have played a more important role in preserving our ancestors. Until now, the sudden increase in frequency of these genes in human groups was masked by the exchange of DNA between people during reproduction. Now, analyses of more than one thousand ancient genomes dating as far back as 45,000 years ago have found historic signals showing genetic adaptation was more common than previously thought. The study of evolutionary events, says the study’s co-lead author Dr Yassine Souilmi, has increased substantially in recent years, as these are the points where human genetics take historic turns. “Evolutionary events [are] exactly what shape our genetic diversity today,” Souilmi tells Cosmos. “That’s what makes us vulnerable to certain diseases [and] resistant to others. “Having a good understanding of evolution, we can have a better understanding of who we are.” Previous research by the Centre has uncovered a range of evolutionary trends, from historic climate change causing the demise of ancestral lions and bears, to the first interactions between humans and coronaviruses 20,000 years ago. And the broader field of research into ancient DNA has shed light on important moments in human history. Only recently did analyses of ancient genes uncover locations on the human genome associated with surviving Yersinia pestis – the bacterium that causes the bubonic plague. <h2>Single events probably triggered selection</h2> This study, published in Nature Ecology and Evolution, has similarly found environmental events might have been more influential on evolution among Eurasian groups. Such events might lead to a point of natural selection. Take, for instance, the emergence of a pathogen. If such a disease could kill people, those who managed to survive and continue reproducing would pass down favourable traits to subsequent generations. “Natural selection acts in two different mechanisms,” says Souilmi. “It only cares about whether you’re procreating successfully… when it acts, it’s either killing a lot of people, [preventing] some people from reproducing successfully, or some people are just not finding mates because they have some sort of ailment that’s not allowing them to mate successfully, or might make them undesirable. “What we’re finding is that the signal of natural selection we detected in this [research] was likely a single event, because the signal is clustered in time in a very early migration out of Africa. “Not all of the [events] we detected occurred at the same time, but the bulk of them did.” <h2>A mirror to the present</h2> This ‘agnostic’ study did not seek to identify the external pressures leading to the selection events indicated in these ancient genes, but future research by the team will seek to uncover that information. Studies like this, or those into specific pressures like the influence of the Black Death or coronaviruses on humans, show the impact of environmental change on our genetics. Souilmi says this is both insightful and cautionary, as environmental change in the present could be studied by humans in the future. He speculates that changes in the Earth’s climate, or the emergence of new pathogens, likely imposed selection pressures on ancient groups, whether through forcing shortages or changes to food supply or imposing physiological stressors. “Very likely, it’s the environment, the temperature, the weather patterns, that would have somewhat impacted the dietary regime of our ancestors out of Africa, and pathogens would have driven this [genetic] adaptation, which has shaped our genetic diversity now,” Souilmi says. “The direct lesson, socially, now, is that if we’re ever faced with events that are similar to that, we are not as immune to extreme episodes of adaptation where a lot of people might die, or be unable to reproduce. “Unless we do something to counteract the environmental changes, or viruses, bacterial or other pandemics, it could be a bad thing.” This article originally appeared on <a href="https://cosmosmagazine.com/science/human-evolution-driven-by-environment/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Matthew Agius.
