What is doxing, and how can you protect yourself?

<p><em><a href="https://theconversation.com/profiles/rob-cover-13135">Rob Cover</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>The Australian government has brought forward <a href="https://www.theguardian.com/australia-news/2024/feb/12/albanese-government-to-propose-legislation-to-crack-down-on-doxing">plans to criminalise doxing</a>, bringing nationwide attention to the harms of releasing people’s private information to the wider public.</p> <p>The government response comes after the <a href="https://www.smh.com.au/national/hundreds-of-jewish-creatives-have-names-details-taken-in-leak-published-online-20240208-p5f3if.html">public release of almost 600 names</a> and private chat logs of a WhatsApp group of Australian Jewish creative artists discussing the Israel-Hamas war.</p> <p>As a result, some of the people whose details were leaked claim they were harassed, <a href="https://www.theguardian.com/australia-news/2024/feb/09/josh-burns-jewish-whatsapp-group-channel-publication-israel-palestine-clementine-ford">received death threats</a> and even had to go into hiding.</p> <p>While we wait for <a href="https://www.smh.com.au/national/australia-news-live-federal-laws-on-doxxing-to-be-brought-forward-anniversary-of-stolen-generations-apology-20240213-p5f4eh.html?post=p55nen#p55nen">new penalties</a> for doxers under the federal Privacy Act review, understanding doxing and its harms can help. And there are also steps we can all take to minimise the risk.</p> <h2>What is doxing?</h2> <p><a href="https://www.kaspersky.com/resource-center/definitions/what-is-doxing">Doxing</a> (or doxxing) is releasing private information — or “docs”, short for documents — online to the wider public without the user’s consent. This includes information that may put users at risk of harm, especially names, addresses, employment details, medical or financial records, and names of family members.</p> <p>The Australian government <a href="https://ministers.ag.gov.au/media-centre/transcripts/media-conference-parliament-house-13-02-2024">currently defines doxing</a> as the “malicious release” of people’s private information without their consent.</p> <p>Doxing began as a form of unmasking anonymous users, trolls and those using hate speech while <a href="https://www.theatlantic.com/technology/archive/2022/04/doxxing-meaning-libs-of-tiktok/629643/">hiding behind a pseudonym</a>. Recently, it has become a weapon for online abuse, harassment, hate speech and adversarial politics. It is often the outcome of online arguments or polarised public views.</p> <p>It is also becoming more common. Although there is no data for Australia yet, according to media company <a href="https://www.safehome.org/family-safety/doxxing-online-harassment-research/">SafeHome.org</a>, about 4% of Americans report having been doxed, with about half saying their private emails or home addresses have been made public.</p> <p>Doxing is a crime in some countries such as the Netherlands and South Korea. In other places, including Australia, privacy laws haven’t yet caught up.</p> <h2>Why is doxing harmful?</h2> <p>In the context of the <a href="https://theconversation.com/au/topics/israel-hamas-war-146714">Israel-Hamas war</a>, doxing has affected <a href="https://www.haaretz.com/world-news/asia-and-australia/2024-02-06/ty-article/death-threats-boycotts-target-jewish-creatives-in-australia/0000018d-7e43-d636-adef-7eefae580000">both Jewish</a> and <a href="https://edition.cnn.com/2023/10/15/business/palestinian-americans-activists-doxxing/index.html">pro-Palestinian communities and activists</a> in Australia and abroad.</p> <p>Doxing is harmful because it treats a user as an object and takes away their agency to decide what, and how much, personal information they want shared with the wider public.</p> <p>This puts people at very real risk of physical threats and violence, particularly when public disagreement becomes heated. From a broader perspective, doxing also damages the digital ecology, reducing people’s ability to freely participate in public or even private debate through social media.</p> <p>Although doxing is sometimes just inconvenient, it is often used to publicly shame or humiliate someone for their private views. This can take a toll on a person’s mental health and wellbeing.</p> <p>It can also affect a person’s employment, especially for people whose employers require them to keep their attitudes, politics, affiliations and views to themselves.</p> <p>Studies have shown doxing particularly impacts <a href="https://journals.sagepub.com/doi/full/10.1177/0306422015605714">women</a>, including those using dating apps or experiencing family violence. In some cases, children and family members have been threatened because a high-profile relative has been doxed.</p> <p>Doxing is also harmful because it oversimplifies a person’s affiliations or attitudes. For example, releasing the names of people who have joined a private online community to navigate complex views can represent them as only like-minded stereotypes or as participants in a group conspiracy.</p> <h2>What can you do to protect yourself from doxing?</h2> <p>Stronger laws and better platform intervention are necessary to reduce doxing. Some experts believe that the fear of <a href="https://dl.acm.org/doi/abs/10.1145/3476075">punishment</a> can help shape better online behaviours.</p> <p>These punishments may include criminal <a href="https://www.esafety.gov.au/report/what-you-can-report-to-esafety">penalties</a> for perpetrators and <a href="https://www.theaustralian.com.au/breaking-news/doxxing-attack-on-jewish-australians-prompts-call-for-legislative-change/news-story/9a2f3615dbf5594fb521a8959739e1f8#:%7E:text=Alongside%20legislative%20reform%2C%20the%20ECAJ,information%2C%E2%80%9D%20Mr%20Aghion%20said.">deactivating social media accounts</a> for repeat offenders. But better education about the risks and harms is often the best treatment.</p> <p>And you can also protect yourself without needing to entirely withdraw from social media:</p> <ol> <li> <p>never share a home or workplace address, phone number or location, including among a private online group or forum with trusted people</p> </li> <li> <p>restrict your geo-location settings</p> </li> <li> <p>avoid giving details of workplaces, roles or employment on public sites not related to your work</p> </li> <li> <p>avoid adding friends or connections on social media services of people you do not know</p> </li> <li> <p>if you suspect you risk being doxed due to a heated online argument, temporarily shut down or lock any public profiles</p> </li> <li> <p>avoid becoming a target by pursuing haters when it reaches a certain point. Professional and courteous engagement can help avoid the anger of those who might disagree and try to harm you.</p> </li> </ol> <p>Additionally, hosts of private online groups must be very vigilant about who joins a group. They should avoid the trap of accepting members just to increase the group’s size, and appropriately check new members (for example, with a short survey or key questions that keep out people who may be there to gather information for malicious purposes).</p> <p>Employers who require their staff to have online profiles or engage with the public should provide information and strategies for doing so safely. They should also provide immediate support for staff who have been doxed.<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/223428/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/rob-cover-13135"><em>Rob Cover</em></a><em>, Professor of Digital Communication and Co-Director of the RMIT Digital Ethnography Research Centre, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“This is life-changing information”: Shopper discovers little-known Bunnings hack

<p>A shopper has revealed the details of a little-known Bunnings store policy that will ensure a blooming garden. </p> <p>Georgia Magill, a young woman from Perth, was shopping for plants in the hardware store when she was urged by the cashier to keep her receipt.</p> <p>The uni student was shocked why she should hold on to the receipt for a small house plant, as the worker went on to explain why. </p> <p>“She was like, ‘Oh because they come with a 12 month warranty’,” Georgia explained in a now-viral TikTok video.</p> <p>“And then she goes: ‘It doesn’t really matter how they die we’ll just replace them for you within a 12 month period.’”</p> <p>The hardware store created the ‘Perfect Plant Promise’ in February 2020 which states all plants, except for seedlings, can be returned within 12 months of purchase if they die. </p> <p>Bunnings won’t just replace the plant, it also offers money back, if you’d prefer to give up on your gardening dreams.</p> <p>"This is life-changing information,” she concluded in the video. </p> <p>While the policy has been around for several years, many Aussies hadn’t heard of it either, commenting in shock on the TikTok video, which has been viewed almost 1.5 million times. </p> <p>“What? I have literally had Bunnings plants die within weeks,” one wrote,</p> <p>“I did know this… but I also refuse to let Bunnings know how many plants I’ve murdered,” another stated. </p> <p>Another person declared, “It’s such a good idea. I can’t believe I didn’t know it!!”</p> <p>Among the comments were more tips for former and current Bunnings workers, offering some extra tips on how to utilise the policy. </p> <p>“Ex Bunnings worker here, keep the original pot so we know what plant it is, not everyone in store is a plant expert,” one remarked.</p> <p>“(From a Bunnings worker) either take a photo of your receipt or ask for it to be sent via SMS as they fade! For any warranty item,” another suggested. </p> <p>However, one worker urged Aussies not to take advantage of the offer, saying, “We will return your plant with a receipt and ‘proof’ but please don’t abuse this system. Plants die.”</p> <p><em>Image credits: Getty Images / TikTok</em></p>

ChatGPT and other generative AI could foster science denial and misunderstanding – here’s how you can be on alert

<p><em><a href="https://theconversation.com/profiles/gale-sinatra-1234776">Gale Sinatra</a>, <a href="https://theconversation.com/institutions/university-of-southern-california-1265">University of Southern California</a> and <a href="https://theconversation.com/profiles/barbara-k-hofer-1231530">Barbara K. Hofer</a>, <a href="https://theconversation.com/institutions/middlebury-1247">Middlebury</a></em></p> <p>Until very recently, if you wanted to know more about a controversial scientific topic – stem cell research, the safety of nuclear energy, climate change – you probably did a Google search. Presented with multiple sources, you chose what to read, selecting which sites or authorities to trust.</p> <p>Now you have another option: You can pose your question to ChatGPT or another generative artificial intelligence platform and quickly receive a succinct response in paragraph form.</p> <p>ChatGPT does not search the internet the way Google does. Instead, it generates responses to queries by <a href="https://www.washingtonpost.com/technology/2023/05/07/ai-beginners-guide/">predicting likely word combinations</a> from a massive amalgam of available online information.</p> <p>Although it has the potential for <a href="https://hbr.org/podcast/2023/05/how-generative-ai-changes-productivity">enhancing productivity</a>, generative AI has been shown to have some major faults. It can <a href="https://www.scientificamerican.com/article/ai-platforms-like-chatgpt-are-easy-to-use-but-also-potentially-dangerous/">produce misinformation</a>. It can create “<a href="https://www.nytimes.com/2023/05/01/business/ai-chatbots-hallucination.html">hallucinations</a>” – a benign term for making things up. And it doesn’t always accurately solve reasoning problems. For example, when asked if both a car and a tank can fit through a doorway, it <a href="https://www.nytimes.com/2023/03/14/technology/openai-new-gpt4.html">failed to consider both width and height</a>. Nevertheless, it is already being used to <a href="https://www.washingtonpost.com/media/2023/01/17/cnet-ai-articles-journalism-corrections/">produce articles</a> and <a href="https://www.nytimes.com/2023/05/19/technology/ai-generated-content-discovered-on-news-sites-content-farms-and-product-reviews.html">website content</a> you may have encountered, or <a href="https://www.nytimes.com/2023/04/21/opinion/chatgpt-journalism.html">as a tool</a> in the writing process. Yet you are unlikely to know if what you’re reading was created by AI.</p> <p>As the authors of “<a href="https://global.oup.com/academic/product/science-denial-9780197683330">Science Denial: Why It Happens and What to Do About It</a>,” we are concerned about how generative AI may blur the boundaries between truth and fiction for those seeking authoritative scientific information.</p> <p>Every media consumer needs to be more vigilant than ever in verifying scientific accuracy in what they read. Here’s how you can stay on your toes in this new information landscape.</p> <h2>How generative AI could promote science denial</h2> <p><strong>Erosion of epistemic trust</strong>. All consumers of science information depend on judgments of scientific and medical experts. <a href="https://doi.org/10.1080/02691728.2014.971907">Epistemic trust</a> is the process of trusting knowledge you get from others. It is fundamental to the understanding and use of scientific information. Whether someone is seeking information about a health concern or trying to understand solutions to climate change, they often have limited scientific understanding and little access to firsthand evidence. With a rapidly growing body of information online, people must make frequent decisions about what and whom to trust. With the increased use of generative AI and the potential for manipulation, we believe trust is likely to erode further than <a href="https://www.pewresearch.org/science/2022/02/15/americans-trust-in-scientists-other-groups-declines/">it already has</a>.</p> <p><strong>Misleading or just plain wrong</strong>. If there are errors or biases in the data on which AI platforms are trained, that <a href="https://theconversation.com/ai-information-retrieval-a-search-engine-researcher-explains-the-promise-and-peril-of-letting-chatgpt-and-its-cousins-search-the-web-for-you-200875">can be reflected in the results</a>. In our own searches, when we have asked ChatGPT to regenerate multiple answers to the same question, we have gotten conflicting answers. Asked why, it responded, “Sometimes I make mistakes.” Perhaps the trickiest issue with AI-generated content is knowing when it is wrong.</p> <p><strong>Disinformation spread intentionally</strong>. AI can be used to generate compelling disinformation as text as well as deepfake images and videos. When we asked ChatGPT to “<a href="https://www.scientificamerican.com/article/ai-platforms-like-chatgpt-are-easy-to-use-but-also-potentially-dangerous/">write about vaccines in the style of disinformation</a>,” it produced a nonexistent citation with fake data. Geoffrey Hinton, former head of AI development at Google, quit to be free to sound the alarm, saying, “It is hard to see how you can prevent the bad actors from <a href="https://www.nytimes.com/2023/05/01/technology/ai-google-chatbot-engineer-quits-hinton.html">using it for bad things</a>.” The potential to create and spread deliberately incorrect information about science already existed, but it is now dangerously easy.</p> <p><strong>Fabricated sources</strong>. ChatGPT provides responses with no sources at all, or if asked for sources, may present <a href="https://economistwritingeveryday.com/2023/01/21/chatgpt-cites-economics-papers-that-do-not-exist/">ones it made up</a>. We both asked ChatGPT to generate a list of our own publications. We each identified a few correct sources. More were hallucinations, yet seemingly reputable and mostly plausible, with actual previous co-authors, in similar sounding journals. This inventiveness is a big problem if a list of a scholar’s publications conveys authority to a reader who doesn’t take time to verify them.</p> <p><strong>Dated knowledge</strong>. ChatGPT doesn’t know what happened in the world after its training concluded. A query on what percentage of the world has had COVID-19 returned an answer prefaced by “as of my knowledge cutoff date of September 2021.” Given how rapidly knowledge advances in some areas, this limitation could mean readers get erroneous outdated information. If you’re seeking recent research on a personal health issue, for instance, beware.</p> <p><strong>Rapid advancement and poor transparency</strong>. AI systems continue to become <a href="https://www.nytimes.com/2023/05/01/technology/ai-google-chatbot-engineer-quits-hinton.html">more powerful and learn faster</a>, and they may learn more science misinformation along the way. Google recently announced <a href="https://www.nytimes.com/2023/05/10/technology/google-ai-products.html">25 new embedded uses of AI in its services</a>. At this point, <a href="https://theconversation.com/regulating-ai-3-experts-explain-why-its-difficult-to-do-and-important-to-get-right-198868">insufficient guardrails are in place</a> to assure that generative AI will become a more accurate purveyor of scientific information over time.</p> <h2>What can you do?</h2> <p>If you use ChatGPT or other AI platforms, recognize that they might not be completely accurate. The burden falls to the user to discern accuracy.</p> <p><strong>Increase your vigilance</strong>. <a href="https://www.niemanlab.org/2022/12/ai-will-start-fact-checking-we-may-not-like-the-results/">AI fact-checking apps may be available soon</a>, but for now, users must serve as their own fact-checkers. <a href="https://www.nsta.org/science-teacher/science-teacher-januaryfebruary-2023/plausible">There are steps we recommend</a>. The first is: Be vigilant. People often reflexively share information found from searches on social media with little or no vetting. Know when to become more deliberately thoughtful and when it’s worth identifying and evaluating sources of information. If you’re trying to decide how to manage a serious illness or to understand the best steps for addressing climate change, take time to vet the sources.</p> <p><strong>Improve your fact-checking</strong>. A second step is <a href="https://doi.org/10.1037/edu0000740">lateral reading</a>, a process professional fact-checkers use. Open a new window and search for <a href="https://www.nsta.org/science-teacher/science-teacher-mayjune-2023/marginalizing-misinformation">information about the sources</a>, if provided. Is the source credible? Does the author have relevant expertise? And what is the consensus of experts? If no sources are provided or you don’t know if they are valid, use a traditional search engine to find and evaluate experts on the topic.</p> <p><strong>Evaluate the evidence</strong>. Next, take a look at the evidence and its connection to the claim. Is there evidence that genetically modified foods are safe? Is there evidence that they are not? What is the scientific consensus? Evaluating the claims will take effort beyond a quick query to ChatGPT.</p> <p><strong>If you begin with AI, don’t stop there</strong>. Exercise caution in using it as the sole authority on any scientific issue. You might see what ChatGPT has to say about genetically modified organisms or vaccine safety, but also follow up with a more diligent search using traditional search engines before you draw conclusions.</p> <p><strong>Assess plausibility</strong>. Judge whether the claim is plausible. <a href="https://doi.org/10.1016/j.learninstruc.2013.03.001">Is it likely to be true</a>? If AI makes an implausible (and inaccurate) statement like “<a href="https://www.usatoday.com/story/news/factcheck/2022/12/23/fact-check-false-claim-covid-19-vaccines-caused-1-1-million-deaths/10929679002/">1 million deaths were caused by vaccines, not COVID-19</a>,” consider if it even makes sense. Make a tentative judgment and then be open to revising your thinking once you have checked the evidence.</p> <p><strong>Promote digital literacy in yourself and others</strong>. Everyone needs to up their game. <a href="https://theconversation.com/how-to-be-a-good-digital-citizen-during-the-election-and-its-aftermath-148974">Improve your own digital literacy</a>, and if you are a parent, teacher, mentor or community leader, promote digital literacy in others. The American Psychological Association provides guidance on <a href="https://www.apa.org/topics/social-media-internet/social-media-literacy-teens">fact-checking online information</a> and recommends teens be <a href="https://www.apa.org/topics/social-media-internet/health-advisory-adolescent-social-media-use">trained in social media skills</a> to minimize risks to health and well-being. <a href="https://newslit.org/">The News Literacy Project</a> provides helpful tools for improving and supporting digital literacy.</p> <p>Arm yourself with the skills you need to navigate the new AI information landscape. Even if you don’t use generative AI, it is likely you have already read articles created by it or developed from it. It can take time and effort to find and evaluate reliable information about science online – but it is worth it.<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/204897/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/gale-sinatra-1234776">Gale Sinatra</a>, Professor of Education and Psychology, <a href="https://theconversation.com/institutions/university-of-southern-california-1265">University of Southern California</a> and <a href="https://theconversation.com/profiles/barbara-k-hofer-1231530">Barbara K.

Four artists explain how science informs and inspires their work

<p>“The greatest scientists are artists as well,” said Albert Einstein. For as long as artistic expression has existed, it has benefited from interplay with scientific principles – be it experimentation with new materials or the discovery of techniques to render different perspectives. Likewise, art has long contributed to the work and communication of science.</p> <p>We asked four outstanding artists to comment on their work and its relationship to science. “Science is my muse,” replied Xavier Cortada, who marked the discovery of the ‘God particle’ with a set of triumphal banners. The same can be said for the other three: Suzanne Anker renders small worlds in petri dishes, Lia Halloran explores serendipity in science, and Daniel Zeller translates images from alien realms in his own artistic language.</p> <p>Credit: Raul Valverde</p> <p><strong>Suzanne Anker</strong></p> <p><img style="width: 496px; height: 496px;" src="https://oversixtydev.blob.core.windows.net/media/7843784/art-suzanne-anker-um.jpg" alt="" data-udi="umb://media/b5d9c04404f441f7a95f03be92b1a842" /></p> <p>Employed as a container for working with fungi, bacteria and even embryos, the glass dish named after bacteriologist Jules Petri is not only a fundamental of laboratory research: it has become a cultural icon.</p> <p>In my Remote Sensing series I use the Petri dish to juxtapose microscopic and macroscopic worlds. The title refers to new digital technologies that can picture places too toxic or inaccessible to visit.</p> <p>The fabrication of this piece began with 2D digital photographs, which were then converted into 3D virtual models. This petri dish with its luxuriant growth emerged from the 3D printer.</p> <p>These micro-landscapes offer the viewer a top-down topographic effect assembled by zeros and ones. Each configuration of these works takes the geometry of a circle, inspired by the Petri dish, and crosses the divide between the disciplines of art and science.</p> <p>The ‘bio art’ of Suzanne Anker explores the intersection of art and the biological sciences. Based in New York, Anker works in a variety of traditional and experimental mediums ranging from digital sculpture and installation to large-scale photography and plants grown under LED lights. Her work has been exhibited at the J. Paul Getty Museum in Los Angeles, the Pera Museum in Istanbul, and the International Biennial of Contemporary Art of Cartagena de Indias, Colombia. Anker is co-author of The Molecular Gaze: Art in the Genetic Age (2004) and co-editor of Visual Culture and Bioscience (2008). </p> <p><a href="http://www.suzanneanker.com">www.suzanneanker.com</a></p> <p>Credit: Lia Halloran</p> <p><strong>Lia Halloran</strong></p> <p><img style="width: 500px; height: 500px;" src="https://oversixtydev.blob.core.windows.net/media/7843785/art-lia-halloran-um.jpg" alt="" data-udi="umb://media/b408465517604d788b927db09d523746" /></p> <p>The 18th-century French astronomer Charles Messier set his telescopic sights on the grand prize of finding a lonely, wandering comet. He ended up amassing an astronomical inventory filled with galaxies, clusters and nebulae. A catalogue of 110 objects is credited to his journals and drawings.</p> <p>Deep Sky Companion is a series of 110 pairs of paintings and photographs of night sky objects drawn from the Messier catalogue.</p> <p>These works are about discovery and all the things we find when we are not seeking them. It relates to my own challenging first stabs at observing the night sky. In college I was given a small Celestron telescope for Christmas. Observing the Orion Nebula and nearby galaxies seemed to create a fold in time between Messier and myself.</p> <p>I would imagine his sessions observing through his telescope and the drawings he made to classify the natural world and make sense of the unknown above him.</p> <p>Each painting in the Deep Sky Companion series was created in ink on semi-transparent paper, which was then used as a negative to create the positive photographic equivalent using standard black-and-white darkroom printing. This process connects to the historical drawings by Messier, here redrawn and then turned back into positives through a photographic process mimicking early glass-plate astrophotography.</p> <p>Lia Halloran is an artist and academic based in Los Angeles. At Chapman University, in California’s Orange County, she teaches painting as well as courses that explore the intersection of art and science. Her art often makes use of scientific concepts and explores how perception, time and scale inform the human desire to understand the world, and our emotional and psychological place within it. She has held solo exhibitions in New York, Miami, Boston, Los Angeles, London, Vienna and Florence. Her work is held in public collections that include the Guggenheim in New York. </p> <p><a href="http://www.liahalloran.com">www.liahalloran.com</a></p> <p>Credit: Courtesy NASA Art Program</p> <p><strong>Daniel Zeller</strong></p> <p><img style="width: 440px; height: 440px;" src="https://oversixtydev.blob.core.windows.net/media/7843786/art-daniel-zeller-um.jpg" alt="" data-udi="umb://media/0f926a1a4fbf4b3ba0ca9804420ba3a8" /></p> <p>I was very grateful to have the Cassini mission as a launching point for this drawing. (Cassini’s 20-year mission ended in September 2017 when it crashed into Saturn.) There are obvious reasons Titan is so appealing: Saturn’s largest moon has an atmosphere, deserts and seas – it is an alien world with some characteristics we can relate to.</p> <p>The probe generated so much fascinating source material it was difficult to choose any single viewpoint, but there was something particularly intriguing about the image of Titan I finally settled on. Greyscale imagery naturally lends itself to broad interpretation, and the radar-mapping method suited my curiosity and my process; it seems to relay its subject as somehow simultaneously familiar and completely alien. Titan’s surface became a scaffold on which I could build and explore. The relative ambiguity of the source image allowed me wide latitude to interpret the moon as a stand-in for any not-yet-discovered world or landscape, while still allowing it to be grounded in the recognisable projection of topography.</p> <p>The Cassini mission was a truly amazing foray into the unknown. We are greatly enriched by the knowledge it collected. My work is but a humble homage to our immediate neighbourhood – once so far away and now a little bit closer – and to what is yet to be discovered on many frontiers.</p> <p>Daniel Zeller is an illustrator and painter based in New York.

My art wound up honouring the Nobel Prize-winning discovery of the Higgs boson, the particle that imbues all the others with mass. Five banners depict the five experiments used to make the discovery.</p> <p>Identifying the Higgs required the most complex machine humans have ever built, the Large Hadron Collider (LHC). The particle accelerator shoots protons at almost the speed of light along a 27 km tunnel. Every second 40 million protons collide with one another. These high-energy collisions make new particles and new mass.</p> <p>The LHC’s detectors did not directly measure the Higgs.</p> <p>They measured the paths taken by the photons, quarks and electrons created in the collisions. The curvature of the paths  revealed the charge and momentum of the particles, and the size of the signal their energy. The data told scientists there was another particle – the Higgs boson – produced in the collisions.</p> <p>Let me tell you why these experiments were so important. When physicists first came up with the Standard Model of physics, a theory to describe the forces and particles of nature, they couldn’t figure out how to give those particles mass.</p> <p>This was quite a problem, because particles with no mass would move at the speed of light and be unable to slow down enough to form atoms. Without atoms the universe would be very different.</p> <p>In the 1960s British physicist Peter Higgs and others independently came up with a theory to solve that problem. Just as marine creatures move in water, all particles in the universe move in a fundamental energy field – now commonly known as the Higgs field. As particles travel through the field, their intrinsic properties generate more or less mass – much as the properties of an animal create different degrees of drag as it moves through water.  Think of a barracuda and a manatee. The sleeker barracuda is going to move faster.</p> <p>Mathematically, the theory required the existence of a particle representing the ‘excited state’ of the field. This new particle – dubbed the Higgs boson – would be to the Higgs field what photons are to the electromagnetic field. Finding the particle involved scientists from 182 universities and institutes in 42 countries. On 4 July 2012, half a century after it was first postulated, CERN scientists announced its discovery.</p> <p>The detection itself was intricate and multilayered, and so were the artworks I created. Stained glass references the LHC as a modern-day cathedral that helps us understand the universe and shape our new world view. The oil painting technique honours those who came before us, the repetition of motifs across the five works celebrates internationalism, and rendering the work as ‘banners’ marks this as a monumental event.</p> <p>Most importantly, the background for the banners honours the scientific collaboration. It is composed of words from the pages of 383 joint publications and the names of more than 4,000 scientists, engineers and technicians. With this piece I wanted to create art from the very words, charts, graphs and ideas of this coalition of thinkers.</p> <p>It was a supremely important moment for humanity. I wanted the art to mark that event at the exact location where the experiment took place. These five banners hang at the exact location of the LHC, where the Higgs boson was discovered. That is where a scientific theory crystallised into a proven truth.</p> <p>It is my hope these banners will inspire future generations of physicists to continue to move humanity forward.</p> <p>Xavier Cortada is a painter based in Miami, Florida. His art regularly involves collaboration with scientists. As well as his art installation for CERN, he has worked with a population geneticist on a project exploring our ancestral journey out of Africa 60,000 years ago, with a molecular biologist to synthesise DNA from participants visiting his museum exhibit, and with botanists on eco-art projects. He estimates his installation at the South Pole using a moving ice sheet as an instrument to mark time will be completed in 150,000 years.</p> <p><a href="http://www.cortada.com">www.cortada.com</a></p> <p><strong>Related reading:</strong></p> <ul> <li><a href="https://cosmosmagazine.com/society/when-arts-and-science-collide/">When arts and science collide</a></li> <li><a href="https://cosmosmagazine.com/biology/how-eye-disorders-may-have-influenced-the-work-of-famous-painters/">Eye disorders influence famous painters</a></li> <li><a href="https://cosmosmagazine.com/technology/sciences-war-on-art-fraud/?hilite=%27artist%27">Science’s war on art fraud</a></li> </ul> <p>This article was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/cosmos-editors">Cosmos</a>. </p>

Surprising new coronavirus symptom has people itching for information

<p>As the world continues to battle coronavirus, new symptoms are emerging that have people looking at their feet.</p> <p>With headaches, muscle aches, a dry cough, fever, chills and losing your sense of taste and smell are established, doctors in Italy have noticed a rash appearing on people diagnosed with coronavirus’ toes.</p> <p>Viral rashes can occur when anyone has a virus, but dermatologists in Italy investigated the rate of skin-related symptoms in COVID-19 patients, they discovered one in five coronavirus patients had developed a rash.</p> <blockquote class="twitter-tweet"> <p dir="ltr">COVID TOES! As more patients throughout the country are getting tested for COVID-19 and more research is being conducted, more symptoms are starting to emerge, including signs and skin changes to your feet...Sudden onset increase redness, pain, blistering, itchiness. <a href="https://twitter.com/hashtag/COVIDTOES?src=hash&amp;ref_src=twsrc%5Etfw">#COVIDTOES</a> <a href="https://t.co/ldm7zA5BqQ">pic.twitter.com/ldm7zA5BqQ</a></p> — Jason Mendivil, DPM (@Dr_JMendivil) <a href="https://twitter.com/Dr_JMendivil/status/1253038875657846786?ref_src=twsrc%5Etfw">April 22, 2020</a></blockquote> <p>Texan dermatologist Dr Sanober Amin sparked interest when she suggested that “some skin findings are more consistent with superficial clotting in blood vessels close to the skin”.</p> <p>“It looks like the blood vessels are getting clotted, so patients are presenting with painful bumps on their toes. A lot of these patients are younger population and most of them didn’t have any COVID symptoms or had mild symptoms to begin with,” she said.</p> <p><iframe src="https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2Fphoto%2F%3Ffbid%3D714584779277938%26set%3Da.363761154360304&amp;show_text=true&amp;width=552&amp;height=702&amp;appId" width="552" height="702" style="border: none; overflow: hidden;" scrolling="no" frameborder="0" allowtransparency="true" allow="encrypted-media"></iframe></p> <p>For scientists, the rash is just more evidence that COVID is one of the “great imitators” as it can present with symptoms that sound like a cold or flu.</p> <p>“There’s clearly a respiratory syndrome, and that’s why people end up in the hospital. Some people get a gastrointestinal illness with diarrhoea, maybe some abdominal pain, which may or may not be associated with a respiratory illness,” Dr Joseph Vinetz, an infectious disease specialist at Yale School of Medicine said.</p> <p>However, Australian infectious diseases expert and ANU Professor Peter Collignon remains cautious.</p> <p>“The one thing that you have to be a bit careful of is people with COVID can have other infections too,’’ he said.</p> <p>“And some of those pictures looked like foot and mouth disease, which is a virus children get. So, you’ve got to be careful that what’s being attributed to COVID is not just another virus they have at the same time.</p> <p>“You can’t assume that just because someone has COVID that COVID is the cause of a rash.”</p> <p>The phenomena of COVID toes has not yet been recognised as a symptom by the World Health Organisation and more work needs to be done to investigate whether or not it is a legitimate symptom.</p> <p>“This is a manifestation that occurs early on in the disease, meaning you have this first, then you progress,” says the University of Pennsylvania’s chief of infectious disease Dr Ebbing Lautenbach.</p> <p> “Sometimes this might be your first clue that they have COVID when they don’t have any other symptoms.”</p> <p>“The short answer is, nobody knows.”</p>

How the use of lasers and small satellites helps information get through space

<p>Satellites are becoming increasingly important in our lives, as they help us meet a demand for more data, exchanged at higher speeds. This is why we are exploring new ways of improving satellite communication.</p> <p>Satellite technology is used to navigate, forecast the weather, monitor Earth from space, receive TV signals from space, and connect to remote places through tools such as satellite phones and <a href="https://www.nbnco.com.au/learn/network-technology/sky-muster-explained">NBN’s Sky Muster satellites</a>.</p> <p>All these communications use radio waves. These are electromagnetic waves that propagate through space and, to a certain degree, through obstacles such as walls.</p> <p>Each communication system uses a frequency band allocated for it, and each band makes up part of the <a href="https://imagine.gsfc.nasa.gov/science/toolbox/emspectrum1.html">electromagnetic spectrum</a> – which is the name given to the range of all types of electromagnetic radiation.</p> <p>But the electromagnetic spectrum we are able to use with current technology is a finite resource, and is now completely occupied. This means old services have to make room for new ones, or higher frequency bands have to be used.</p> <p>While this poses technological challenges, one promising way forward is optical communication.</p> <p><strong>Communication with lasers</strong></p> <p>Instead of using radio waves to carry the information, we can use light from lasers as the carrier. While technically still part of the electromagnetic spectrum, optical frequencies are significantly higher, which means we can use them to transfer data at higher speeds.</p> <p>However, one disadvantage is that a laser cannot propagate through walls, and can even be blocked by clouds. While this is problematic on Earth, and for communication between satellites and Earth, it’s no problem for communication between satellites.</p> <p>On Earth, optical communication via fibre optic cables connects continents and provides enormous data exchanges. This is the technology that allows <a href="https://www.vox.com/2015/4/30/11562024/too-embarrassed-to-ask-what-is-the-cloud-and-how-does-it-work">the cloud</a> to exist, and online services to be provided.</p> <p>Optical communication between satellites doesn’t use fibre optic cables, but involves light propagating through space. This is called “free space optical communication”, and can be used to not only deliver data from satellites to the ground, but also to connect satellites in space.</p> <p>In other words, free space optical communication will provide the same massive connectivity in space we already have on Earth.</p> <p>Some systems such as the <a href="https://artes.esa.int/edrs-global">European Data Relay System</a> are already operational, and others like SpaceX’s <a href="https://www.space.com/see-spacex-starlink-satellites-in-night-sky.html">Starlink</a> continue to be developed.</p> <p>But there are still many challenges to overcome, and we’re limited by current technology. My colleagues and I are working on making optical, as well as radio-frequency, data links even faster and more secure.</p> <p><strong>CubeSats</strong></p> <p>So far, a lot of effort has gone into the research and development of radio-frequency technology. This is how we know data rates are at their highest physical limit and can’t be further increased.</p> <p>While a single radio-frequency link can provide data rates of 10Gbps with large antennas, an optical link can achieve rates 10 to 100 times higher, using antennas that are 10 to 100 times smaller.</p> <p>These small antennas are in fact optical lenses, and their compact size allows them to be integrated into small satellites called CubeSats.</p> <p>CubeSats are not larger than a shoebox or toaster, but can employ high speed data links to other satellites or the ground.</p> <p>They are currently used for a wide range of tasks including earth observation, communications and scientific experiments in space. And while they’re not able to provide all services from space, they play an important role in current and future satellite systems.</p> <p>Another advantage of optical communication is increased security. The light from a laser forms a narrow beam, which has to be pointed from a sender to a receiver. Since this beam is very narrow, the communication doesn’t interfere with other receivers and it’s very hard, if not impossible, to eavesdrop on the communication. This makes optical systems more secure than radio electromagnetic systems.</p> <p>Optical communication can also be used for <a href="https://qt.eu/understand/underlying-principles/quantum-key-distribution-qkd/">Quantum Key Distribution</a>. This technology allows the absolute secure exchange of encryption keys for safe communications.</p> <p><strong>What can we expect from this?</strong></p> <p>While it’s exciting to develop systems for space, and to launch satellites, the real benefit of satellite systems is felt on Earth.</p> <p>High speed communication provided by optical data links will improve connectivity for all of us. Notably, remote areas which currently have relatively slow connections will experience better access to remote health and remote learning.</p> <p>Better data links will also let us deliver images and videos from space with less delay and higher resolution. This will improve the way we manage our resources, including <a href="https://www.ga.gov.au/scientific-topics/community-safety/flood/wofs">water</a>, agriculture and forestry.</p> <p>They will also <a href="https://www.ga.gov.au/scientific-topics/earth-obs/case-studies/mapping-bushfires">provide vital real-time information in disaster scenarios such as bushfires</a>. The potential applications of optical communication technology are vast.</p> <p><strong>Banding knowledge together</strong></p> <p>Working in optical satellite communication is challenging, as it combines many different fields and research areas including telecommunication, photonics and manufacturing.</p> <p>Currently, our technology is far from achieving what is theoretically possible, and there’s great room for improvement. This is why there’s a strong focus on collaboration.</p> <p>In Australia, there are two major programs facilitating this - the Australian Space Agency run by the federal government, and the <a href="https://smartsatcrc.com/">SmartSat Cooperative Research Centre</a> (CRC), also supported by the federal government.</p> <p>Through the SmartSat CRC program, my colleagues and I will spend the next seven years tackling a range of applied research problems in this area.<!-- Below is The Conversation's page counter tag.

“Poorly informed teenager”: Vladimir Putin weighs in on Greta Thunberg

<p>Russian President Vladimir Putin has taken aim at Swedish schoolgirl and climate change activist Greta Thunberg, calling her a “poorly informed teenager” who is being “used by adults”. </p> <p>The world leader, 66, said the 16-year-old should quit “telling developing countries why they should live in poverty” over her campaign to cut fossil fuel use.</p> <p>While at the energy forum today Putin expressed he did not share the same excitement about Thunberg’s United Nations speech last month. </p> <p>The swede unleashed at the UN summit in New York when she denounced world leaders for failing to tackle climate change issues. </p> <p>While Putin did not name any specific groups, he said it was “deplorable” Thunberg was being used by groups to achieve their own goals. </p> <p>“I may disappoint you,” the Russian leader said at  a session titled<span> </span>Energy Partnership for Sustainable Growth<span> </span>in Moscow, Russia. </p> <p> “But I don't share the common excitement about the speech by Greta Thunberg.</p> <p>“No one has explained to Greta that the modern world is complex and different and...people in Africa or in many Asian countries want to live at the same wealth level as in Sweden.</p> <p>“Go and explain to developing countries why they should continue living in poverty and not be like Sweden.”</p> <p>US President Donald Trump mocked Thunberg and Canadian Member of Parliament Maxime Bernier labelled her alarmist and mentally unstable. </p> <p>Thunberg was not deterred by the comments however and said the mockery of children who were protesting showed her message had become “too loud to handle”. </p> <p>Putin said while young people who paid attention to environmental issues should be supported, he believes: “when someone is using children and teenagers in personal interests, it only deserves to be condemned.</p> <p>“I'm sure that Greta is a kind and very sincere girl. But adults must do everything not to bring teenagers and children into some extreme situations.”</p> <p>Thunberg made international headlines in September as she inspired millions of people across 150 countries to take to the streets for the Global Strike 4 Climate.</p>

Are you at risk? Data sharing amongst health apps is more common than you think

<p><span style="font-weight: 400;">Some of the sensitive information you might share with a doctor, including your age, sex, medical conditions and current symptoms, are being shared with popular health apps.</span></p> <p><span style="font-weight: 400;">Although it’s easy to feel like these applications are helping you, a new study has found that the data that users input into these apps are being shared with third party entities.</span></p> <p><span style="font-weight: 400;">The study, published in the </span><a href="https://www.bmj.com/content/364/bmj.l920"><span style="font-weight: 400;">British Medical Journal</span></a><span style="font-weight: 400;">, has found that user data from health-related mobile apps on the Android platform is routine and not transparent at all.</span></p> <p><span style="font-weight: 400;">The information that is put into these health apps can be shared with app developers, their parent companies and potentially dozens of third-party entities. Therefore, the information that you think is private ends up being distributed on a wide scale.</span></p> <p><span style="font-weight: 400;">Lead author of the report, Dr Quinn Grundy, said that health apps are a “booming market”, but is one with many privacy failings. She told </span><a href="https://www.abc.net.au/news/science/2019-03-21/health-apps-sharing-data-common-practice-study-finds/10923484"><span style="font-weight: 400;">The ABC</span></a><span style="font-weight: 400;">:</span></p> <p><span style="font-weight: 400;">"I think many of us would expect that this kind of data should be treated differently," said Dr Grundy, an assistant professor at the University of Toronto.</span></p> <p><span style="font-weight: 400;">"Unfortunately, our study shows that that's not the case. These apps behave in much the same way as your fitness app, weather app or music app."</span></p> <p><span style="font-weight: 400;">Dr Grundy and colleagues at the University of Sydney examined 24 medicine related Android applications that are popular in Australia, North America and the United Kingdom. Some of these apps included ones that might remind you when to take a prescription.</span></p> <p><span style="font-weight: 400;">The researchers found that 19 out of 24 apps shared data outside of the application to a total of 55 different entities, owned by 46 parent companies.</span></p> <p><span style="font-weight: 400;">The information that was shared included users emails and device ID to medical conditions and drug lists.</span></p> <p><span style="font-weight: 400;">The researchers discovered that Amazon and Alphabet, the parent company of Google, received the highest volume of user data. This was closely followed by Microsoft.</span></p> <p><span style="font-weight: 400;">Dr Grundy explained that whilst most apps have a privacy policy and said that the data was stripped of identifying information, they described what was collected and shared in very general terms.</span></p> <p><span style="font-weight: 400;">"They wouldn't name specific third parties or why data was shared with them. But would say, 'we never sell your data, but we may shared anonymised, aggregated reports with third parties for legitimate business purposes'," she explained.</span></p> <p><span style="font-weight: 400;">Peter Hannay, an adjunct lecturer and security researcher at Edith Cowan University has offered a solution.</span></p> <p><span style="font-weight: 400;">"It's not a matter of 'swap to a different app'," he said.</span></p> <p><span style="font-weight: 400;">"It would be a matter of just not using those sorts of services at all."</span></p> <p><span style="font-weight: 400;">However, if you do want to use these services, he has some advice for that as well.</span></p> <p><span style="font-weight: 400;">"If the application is reminding you to take medication, I would try to find one that doesn't require permission to connect to the internet," he said.</span></p> <p><span style="font-weight: 400;">"If it's able to work offline, that's something I would consider to be desirable."</span></p> <p><span style="font-weight: 400;">Do you use any apps that require health data?

6 golden rules to keep your smartphone safe while travelling

<p>New technology means you have to think about a whole new kind of theft while on the road – the information stored on your smartphone.</p> <p><strong>1. Be careful of public Wi-Fi</strong></p> <p>Data usage can be a huge expense when travelling, so it’s always nice to see a free Wi-Fi network that doesn’t require a password pop up on your phone. Before you log on, keep in mind that these networks are accessible to everyone – including the bad guys who will try to hack into your phone. Try to use encrypted networks that require a log in as these can provide a higher level of security.</p> <p><strong>2. Turn off Bluetooth pairings</strong></p> <p>Bluetooth provides another avenue for hackers to access your phone. Switch your Bluetooth settings to ‘non-discoverable’, which means that any other devices around you won’t be able to see you. If you see a request for pairing come up from an unknown device, always reject it.</p> <p><strong>3. Don’t save your important details</strong></p> <p>It can be much easier to save your passwords or even credit card details on your phone so you don’t have to reenter them every time. But using the autofill feature means that if someone does manage to hack your phone, they have all of your details ready to go.</p> <p><strong>4. Keep your device up to date</strong></p> <p>Make sure that your phone is operating on the latest software update. These will generally include the best security settings to protect you from unsafe networks. If you’re really worried, you can install a third party security app that will act like virus protection software on your computer. This can be useful if you’re travelling in a country where malware is especially prevalent, like China or Russia.</p> <p><strong>5. Resist the urge to click</strong></p> <p>One of the most common ways that malware gets into your phone is because you invite it. If you’re browsing the web or using a new app, be wary of pop ups that ask you to click to continue or to agree to terms. A good rule of thumb is if you see anything you don’t trust come onto your screen, close the application immediately.</p> <p><strong>6. Secure the device itself</strong></p> <p>Your data is also in danger if you lose or someone steals the phone itself. This little device can give them access to just about everything you use, from your email to social media and even things like bank accounts. Make sure your phone always requires a PIN to unlock or some will even let you use a fingerprint.</p> <p>Do you generally take your smartphone on holidays, and what measures do you take to ensure its safe? Do you think it’s worth having on your trip?</p> <p>Share your thoughts in the comments.</p> <p><strong>Related links:</strong></p> <p><a href="/health/body/2016/06/tips-to-stop-eye-strain-from-phones-and-tablets/"><span style="text-decoration: underline;"><em><strong>5 tips to stop eye strain from phones and tablets</strong></em></span></a></p> <p><a href="/entertainment/technology/2016/06/how-a-mobile-phone-can-save-your-life/"><span style="text-decoration: underline;"><em><strong>How a mobile phone can save your life</strong></em></span></a></p> <p><a href="/travel/international/2016/06/flight-attendant-tips-for-an-easy-flight/" target="_blank"><span style="text-decoration: underline;"><strong><em>Flight attendant reveals 6 top tips for an easy fight</em></strong></span></a></p>
