OpenAI Says Dead Teen Violated TOS When He Used ChatGPT To Plan Suicide

Par :BeauHD
27 novembre 2025 à 00:02
An anonymous reader quotes a report from Ars Technica: Facing five lawsuits alleging wrongful deaths, OpenAI lobbed its first defense Tuesday, denying in a court filing that ChatGPT caused a teen's suicide and instead arguing the teen violated terms that prohibit discussing suicide or self-harm with the chatbot. The earliest look at OpenAI's strategy to overcome the string of lawsuits came in a case where parents of 16-year-old Adam Raine accused OpenAI of relaxing safety guardrails that allowed ChatGPT to become the teen's "suicide coach." OpenAI deliberately designed the version their son used, ChatGPT 4o, to encourage and validate his suicidal ideation in its quest to build the world's most engaging chatbot, parents argued. But in a blog, OpenAI claimed that parents selectively chose disturbing chat logs while supposedly ignoring "the full picture" revealed by the teen's chat history. Digging through the logs, OpenAI claimed the teen told ChatGPT that he'd begun experiencing suicidal ideation at age 11, long before he used the chatbot. "A full reading of his chat history shows that his death, while devastating, was not caused by ChatGPT," OpenAI's filing argued. [...] All the logs that OpenAI referenced in its filing are sealed, making it impossible to verify the broader context the AI firm claims the logs provide. In its blog, OpenAI said it was limiting the amount of "sensitive evidence" made available to the public, due to its intention to handle mental health-related cases with "care, transparency, and respect." The Raine family's lead lawyer called OpenAI's response "disturbing." "They abjectly ignore all of the damning facts we have put forward: how GPT-4o was rushed to market without full testing. That OpenAI twice changed its Model Spec to require ChatGPT to engage in self-harm discussions. That ChatGPT counseled Adam away from telling his parents about his suicidal ideation and actively helped him plan a 'beautiful suicide.' And OpenAI and Sam Altman have no explanation for the last hours of Adam's life, when ChatGPT gave him a pep talk and then offered to write a suicide note." OpenAI is leaning on its usage policies to defend against this case, emphasizing that "ChatGPT users acknowledge their use of ChatGPT is 'at your sole risk'" and that Raine should never have been allowed to use the chatbot without parental consent.

Newegg Sparks Debate With New PayPal-Integrated AI Shopping Push

BrianFagioli writes: Newegg's new partnership with PayPal is another sign that mainstream e-commerce is shifting control from users to AI-driven intermediaries. Instead of shoppers visiting Newegg directly, PayPal's agentic commerce system pushes product discovery through AI platforms like Perplexity where recommendations, checkout, and fraud checks all happen inside someone else's controlled environment. Newegg stays the merchant of record, but the real influence shifts to the platforms that decide which products their AI agents mention. That may sound convenient, but it also means discovery becomes guided by training data and commercial integrations rather than user intent. Slashdot readers will likely notice the other issue. This setup puts PayPal deeper into the shopping pipeline at a time when many users already avoid the company over account freezes and dispute policies. An AI-mediated shopping experience where PayPal becomes the silent gatekeeper by default is not going to sit well with everyone. And with AI agents shaping purchasing decisions based on behavior and context, the concept of intent-driven shopping starts to look a lot like quiet nudging rather than empowerment. Newegg may see this as the future, but the community will probably ask whether users truly want AI systems and PayPal deciding how they shop.

European Lawmakers Seek EU-Wide Minimum Age To Access AI Chatbots, Social Media

Par :BeauHD
26 novembre 2025 à 21:25
The European Parliament has passed a non-binding resolution urging an EU-wide minimum age of 16 to access social media, video-sharing platforms, and AI chatbots, with parental consent allowed for ages 13-16 and a hard ban for anyone under 13. "It also proposes additional measures, including a ban on addictive design features that keep children hooked to screens and manipulative advertising and gambling-like elements," reports Reuters. Furthermore, the draft "calls for the outright blocking of websites that don't follow EU rules and to address AI tools that can create fake or inappropriate content." The resolution "carries no legal weight" but reflects the growing concern on the issue of AI companions and algorithm-driven platforms even. "Any binding legislation would require formal proposals from the European Commission, followed by negotiations between EU member states and Parliament in a process that typically takes years to complete," notes the report.

More Than Half of New Articles On the Internet Are Being Written By AI

Par :BeauHD
26 novembre 2025 à 20:45
An anonymous reader quotes a report from the Conversation: The line between human and machine authorship is blurring, particularly as it's become increasingly difficult to tell whether something was written by a person or AI. Now, in what may seem like a tipping point, the digital marketing firm Graphite recently published a study showing that more than 50% of articles on the web are being generated by artificial intelligence. [...] It's important to clarify what's meant by "online content," the phrase used in the Graphite study, which analyzed over 65,000 randomly selected articles of at least 100 words on the web. These can include anything from peer-reviewed research to promotional copy for miracle supplements. A closer reading of the Graphite study shows that the AI-generated articles consist largely of general-interest writing: news updates, how-to guides, lifestyle posts, reviews and product explainers. The primary economic purpose of this content is to persuade or inform, not to express originality or creativity. Put differently, AI appears to be most useful when the writing in question is low-stakes and formulaic: the weekend-in-Rome listicle, the standard cover letter, the text produced to market a business. A whole industry of writers -- mostly freelance, including many translators -- has relied on precisely this kind of work, producing blog posts, how-to material, search engine optimization text and social media copy. The rapid adoption of large language models has already displaced many of the gigs that once sustained them. The dramatic loss of this work points toward another issue raised by the Graphite study: the question of authenticity, not only in identifying who or what produced a text, but also in understanding the value that humans attach to creative activity. How can you distinguish a human-written article from a machine-generated one? And does that ability even matter? Over time, that distinction is likely to grow less significant, particularly as more writing emerges from interactions between humans and AI... "If you set aside the more apocalyptic scenarios and assume that AI will continue to advance -- perhaps at a slower pace than in the recent past -- it's quite possible that thoughtful, original, human-generated writing will become even more valuable," writes author Francesco Agnellini, in closing. "Put another way: The work of writers, journalists and intellectuals will not become superfluous simply because much of the web is no longer written by humans."

Texas Buys $5 Million In BTC ETF As States Edge Toward First Government Crypto Reserves

Texas has purchased $5 million worth of BlackRock's bitcoin ETF as an initial step toward creating the first state-level bitcoin reserve in the U.S. "[O]ther states having previously invested in such funds with public-employee retirement money," notes CoinDesk. "Michigan has been building such an investment, and Wisconsin sold its $350 million pension-fund stake in the BlackRock ETF in May. From the report: A few weeks ago, Texas moved past its deadline to "capture the industry's best practices so it can utilize these practices in the implementation and management" of its bitcoin BTC reserve, according to its formal request for information issued in September. Entities across the industry provided input on how it could set up and manage the stockpile conceived of in the Texas Strategic Bitcoin Reserve and Investment Act. Last week, the state comptroller's office moved to secure $5 million in BlackRock's iShares Bitcoin Trust (IBIT) as a placeholder, a spokesman for the Texas Comptroller of Public Accounts told CoinDesk on Tuesday. It's an opening move as the state continues to work toward a contract with a custodian, he said, which will take place after it develops its formal request for proposal.

Study Claims To Provide First Direct Evidence of Dark Matter

Par :BeauHD
26 novembre 2025 à 10:00
An anonymous reader quotes a report from the Guardian: Nearly a century ago, scientists proposed that a mysterious invisible substance they named dark matter clumped around galaxies and formed a cosmic web across the universe. What dark matter is made from, and whether it is even real, are still open questions, but according to a study, the first direct evidence of the substance may finally have been glimpsed. More work is needed to rule out less exotic explanations, but if true, the discovery would go down as a turning point in the decades-long search for the elusive substance that is said to make up 27% of the cosmos. "This could be a crucial breakthrough in unraveling the nature of dark matter," said Prof Tomonori Totani, an astrophysicist at the University of Tokyo, who said gamma rays emanating from the centre of the Milky Way appeared to bear the signature of the substance. [...] To search for potential dark matter signals, Totani analysed data from Nasa's Fermi Gamma-ray Space Telescope, which detects the most energetic photons in the electromagnetic spectrum. He spotted a pattern of gamma rays that appeared to match the shape of the dark matter halo that spreads out in a sphere from the heart of the galaxy. The signal "closely matches the properties of gamma-ray radiation predicted to be emitted by dark matter," Totani told the Guardian. Details are published in the Journal of Cosmology and Astroparticle Physics. If Totani has seen dark matter at work, the observations suggest it is made from elementary particles 500 times more massive than the proton. But far more work is needed to rule out other astrophysical processes and background emissions that could explain the signals. Totani said the "decisive factor" would be detecting gamma rays with the same spectrum from other regions of space, such as dwarf galaxies. According to Prof Justin Read, an astrophysicist at the University of Surrey, the lack of significant signals from such galaxies strongly argues against Totani having seen gamma rays emitted from dark matter particle annihilation. Prof Kinwah Wu, a theoretical astrophysicist at UCL, urged caution, saying: "I appreciate the author's hard work and dedication, but we need extraordinary evidence for an extraordinary claim," he said. "This analysis has not reached this status yet. It is a piece of work which serves as an encouragement for the workers in the field to keep on pressing."

China Launches An Emergency Lifeboat To Bring Three Astronauts Back To Earth

China launched an uncrewed Shenzhou 22 spacecraft to serve as an emergency lifeboat for three astronauts aboard the Tiangong space station after a docked return craft was found to have a cracked window likely caused by space debris. "A Long March 2F rocket fired its engines and lifted off with the Shenzhou 22 spacecraft, carrying cargo instead of a crew, at 11:11 pm EST Monday (04:11 UTC Tuesday)," reports Ars Technica. "The spacecraft docked with the Tiangong station nearly 250 miles (400 kilometers) above the Earth about three-and-a-half hours later." From the report: Chinese engineers worked fast to move up the launch of the Shenzhou 22, originally set to fly next year. On November 4, astronauts discovered one of the two crew ferry ships docked to the Tiangong station had a damaged window, likely from an impact with a small fragment of space junk. [...] Now, 20 days after the saga began, the Tiangong outpost again has a lifeboat for its long-term residents. Astronauts Zhang Lu, Fu Wei, and Zhang Hongzhang will return to Earth on the Shenzhou 22 spacecraft next year, soon after the arrival of their three replacements. The Tiangong astronauts will head outside the station on a spacewalk to inspect the damaged window on Shenzhou 20. Eventually, Shenzhou 20 will depart Tiangong and reenter the atmosphere with cargo. Assuming a smooth landing, Chinese engineers will have an opportunity to get a closer look at the damage on the ground to inform the design of future spacecraft. A preliminary assessment of the window indicates the crack is in the outermost layer of heat-insulating glass in Shenzhou 20's porthole window, according to Chinese state media. Engineers on the ground conducted simulations and wind tunnel ablation tests to determine whether the window might fail during reentry. "The results showed that the cracks would still propagate further," reported CCTV, China's government-run television network. "We held review meeting, and everyone agreed that ensuring the safe return of the astronauts was too risky with the glass damaged," Zhou said. While this crew is just one month into their planned six-month expedition, an emergency could force them to leave the station and return home at any time. Although remote, another collision with space junk, a major systems failure, or a medical emergency involving one of the astronauts could trigger an evacuation. That's why Chinese officials wanted to quickly launch Shenzhou 22 to give the crew a ticket home.The International Space Station follows the same policy, with SpaceX's Dragon spacecraft and Russian Soyuz ships serving as lifeboats until their crews' scheduled return to Earth.

Britain Plots Atomic Reboot As Datacenter Demand Surges

Par :BeauHD
26 novembre 2025 à 03:30
The UK is seeking to fast-track new atomic development to meet soaring energy demands driven by AI and electrification. According to a new report published by the government's Nuclear Regulatory Taskforce, excessive regulation has made Britain the most expensive place in the world to build nuclear projects. The report is calling for a sweeping overhaul to accelerate reactor construction -- everything from "streamlining regulation" to relaxing environmental and safety constraints. The Register reports: The document outlines 47 recommendations for the government, which come under five general areas: providing clearer leadership and direction for the nuclear sector; simplifying the regulatory approval process for atomic projects; reducing risk aversion; addressing incentives to delay progress; and working with the nuclear sector to speed delivery and boost innovation. Among the recommendations is that a Commission for Nuclear Regulation should be established, becoming a "unified decision maker" across all other regulators, planners, and approval bodies. The report also talks of reforming environmental and planning regimes to speed approvals, echoing the government's earlier decisions to streamline the planning process to make it easier for datacenter projects to get built. It recommends amending the cost cap for judicial reviews and limiting legal challenges to Nationally Strategic Infrastructure Projects (NSIPs), while indemnifying nuclear developers against any damages they might incur as a result of proceeding with their project while a judicial review is still being decided. Another recommendation that may be cause for concern is that the government should modify the Habitats Regulations to reduce costs. These are rules created to protect the most important and vulnerable natural sites and wildlife species across the UK. The report also states that radiation limits for workers are overly conservative and well below what could be appropriately considered "broadly acceptable," claiming that they are many times less than what the average person in the UK normally receives in a year.

Plex Is Now Enforcing Remote Play Restrictions On TVs

26 novembre 2025 à 02:02
Plex is beginning to enforce new restrictions on remote streaming for its TV apps, requiring either a Plex Pass or the cheaper Remote Watch Pass to watch media from servers outside your home network. How-To Geek reports: Plex is now rolling out the remote watch changes to its Roku TV app. This means that you will need a Plex Pass or Remote Watch Pass for your Plex account if you want to stream media from a server outside your home. If you're only watching media from your own server on the same local network as your Roku device, or the owner of the server you're streaming from has Plex Pass, you don't have to do anything. Plex says this change will come to the other TV apps in 2026, such as Fire TV, Apple TV, and Android TV. Presumably, that will happen when the redesigned app arrives on those platforms. Roku was just the first TV platform to get the new app, which caused a wave of complaints from users about removed functionality and a more clunky redesign. Plex is addressing some of those complaints with more updates, but adding another limitation at the same time isn't a great look. The Remote Watch Pass costs $2 per month or $20 per year, but there's no lifetime purchase option. You can also use a Plex Pass, which normally costs $7 per month, $70 per year, or $250 for a lifetime license. However, there's currently a 40% off sale for Plex Pass subscriptions.

Warner Music Group has reached a licensing deal with Suno that will let users create AI-generated music using the voices and likenesses of artists who opt in. WMG says participating artists will have "full control" over how their likeness and music are used. "These will be new creation experiences from artists who do opt in, which will open up new revenue streams for them and allow you to interact with them in new ways," Suno says, adding that users will be able to "build around" an artist's sounds "and ensure they get compensated." WMG is also dropping its previous lawsuit accusing Suno of scraping copyrighted material. "Along with the licensing agreement, Suno is planning to use licensed music from WMG to build next-gen music generation models that it claims will surpass its flagship v5 model," adds The Verge. "It will also start requiring users to have a paid account to download songs starting next year, with each tier providing a specific number of downloads each month."

An anonymous reader quotes a report from PCMag: Four new features are coming to Google Maps, including a way to hide your identity in reviews. Maps will soon let you use a nickname and select an alternative profile picture for online reviews, so you can rate a business without linking it to full name and Google profile photo. Google says it will monitor for "suspicious and fake reviews," and every review is still associated with an account on Google's backend, which it believes will discourage bad actors. Look for a new option under Your Profile that says Use a custom name & picture for posting. You'll then be able to pick an illustration to represent you and add a nickname. Google didn't explain why it is introducing anonymous reviews; it pitched the idea as a way to be a business's "Secret Santa." Some users are nervous to publicly post reviews for local businesses as it may be used to track their location or movements. It may encourage more people to contribute honest feedback to its platform, for better or worse. Further reading: Gemini AI To Transform Google Maps Into a More Conversational Experience

Poland Probes Apple Again Over App Tracking Transparency Rules

Par :BeauHD

Poland has launched a new antitrust investigation into Apple's App Tracking Transparency rules, questioning whether Apple misled users about privacy while giving its own apps a competitive advantage over third-party developers. AppleInsider reports: On November 25, Poland's UOKiK has started another investigation into App Tracking Transparency, and whether Apple had restricted competition in mobile advertising. Reuters reports that, to the anti-monopoly regulator, ATT may have limited advertisers' ability to collect user data for advertising purposes while simultaneously favoring Apple's ad program. On November 25, Poland's UOKiK has started another investigation into App Tracking Transparency, and whether Apple had restricted competition in mobile advertising. Reuters reports that, to the anti-monopoly regulator, ATT may have limited advertisers' ability to collect user data for advertising purposes while simultaneously favoring Apple's ad program. This is not the first time that Poland has looked into ATT rules. In December 2021, the regulator held a similar probe following criticism from advertisers. It's not clear what that complaint determined, or if it is still ongoing. Regardless, in the new complaint, the logic is that Apple had a competitive advantage since its own apps were not subject to ATT rules, but third-party apps did have to deal with ATT. Since Apple didn't visibly ask for consent for its first-party apps in the same way, there is a presumption that Apple's rules only applied to other companies. This is despite Apple's repeated insistence that it doesn't use the same kinds of collected data in its own apps and services for marketing purposes, as well as its stance on privacy in general. In short, Apple apps don't use the data, so it doesn't pop up a dialog box asking the user if the app can use the data. There is also the argument that, in setting up an account with Apple, users are providing blanket consent to the company. Implementing ATT on its own apps would therefore be a waste of time, since that consent was already granted. Apple said that it will work with the regulator on the matter, but warned that it could force them to withdraw the feature "to the detriment of European consumers."

'AI Can't Think'

Par :BeauHD
25 novembre 2025 à 22:40
In an essay published in The Verge, Benjamin Riley argues that today's AI boom is built on a fundamental misunderstanding: language modeling is not the same as intelligence. "The problem is that according to current neuroscience, human thinking is largely independent of human language -- and we have little reason to believe ever more sophisticated modeling of language will create a form of intelligence that meets or surpasses our own," writes Riley. Slashdot reader RossCWilliams shares the report, writing: The article goes on to point out that we use language to communicate. We use it to create metaphors to describe our reasoning. That people who have lost their language ability can still show reasoning. That human beings create knowledge when they become dissatisfied with the current metaphor. Einstein's theory of relativity was not based on scientific research. He developed it as thought experiment because he was dissatisfied with the existing metaphor. It quotes someone who said, "common sense is a collection of dead metaphors." And that AI, at best, can rearrange those dead metaphors in interesting ways. But it will never be dissatisfied with the data it has or an existing metaphor. A different critique (PDF) has pointed out that even as a language model AI is flawed by its reliance on the internet. The languages used on the internet are unrepresentative of the languages in the world. And other languages contain unique descriptions/metaphors that are not found on the internet. My metaphor for what was discussed was the descriptions of the kinds of snow that exist in Inuit languages that describe qualities nowhere found in European languages. If those metaphors aren't found on the internet, AI will never be able create them. This does not mean that AI isn't useful. But it is not remotely human intelligence. That is just a poor metaphor. We need a better one. Benjamin Riley is the founder of Cognitive Resonance, a new venture to improve understanding of human cognition and generative AI.

US Banks Scramble To Assess Data Theft After Hackers Breach Financial Tech Firm

An anonymous reader quotes a report from TechCrunch: Several U.S. banking giants and mortgage lenders are reportedly scrambling to assess how much of their customers' data was stolen during a cyberattack on a New York financial technology company earlier this month. SitusAMC, which provides technology for over a thousand commercial and real estate financiers, confirmed in a statement over the weekend that it had identified a data breach on November 12. The company said that unspecified hackers had stolen corporate data associated with its banking customers' relationship with SitusAMC, as well as "accounting records and legal agreements" during the cyberattack. The statement added that the scope and nature of the cyberattack "remains under investigation." SitusAMC said that the incident is "now contained," and that its systems are operational. The company said that no encrypting malware was used, suggesting that the hackers were focused on exfiltrating data from the company's systems rather than causing destruction. According to Bloomberg and CNN, citing sources, SitusAMC sent data breach notifications to several financial giants, including JPMorgan Chase, Citigroup, and Morgan Stanley. SitusAMC also counts pension funds and state governments as customers, according to its website. It's unclear how much data was taken, or how many U.S. banking consumers may be affected by the breach. Companies like SitusAMC may not be widely known outside of the financial world, but provide the mechanisms and technologies for its banking and real estate customers to comply with state and federal rules and regulations. In its role as a middleman for financial clients, the company handles vast amounts of non-public banking information on behalf of its customers. According to SitusAMC's website, the company processes billions of documents related to loans annually.

EPA Approves New 'Forever Chemical' Pesticides For Use On Food

Par :BeauHD
25 novembre 2025 à 10:00
The EPA has approved new pesticides that qualify as PFAS "forever chemicals" (paywalled; alternative source), sparking criticism from scientists and environmental groups who warn these decisions could increase Americans' exposure through food and water at a time when many states are moving to restrict such substances. The Washington Post reports: This month, the agency approved two new pesticides that meet the internationally recognized definition for per- and polyfluoroalkyl substances, also known as PFAS or fluorinated substances, and has announced plans for four additional approvals. The authorized pesticides, cyclobutrifluram and isocycloseram, which was approved Thursday, will be used on vegetables such as romaine lettuce, broccoli and potatoes. The agency also announced plans to relax a rule requiring companies to report all products containing PFAS and has proposed weakening drinking water standards for the chemicals. "Many fluorinated compounds registered or proposed for U.S. pesticidal use in recent years offer unique benefits for farmers, users, and the public," EPA spokeswoman Brigit Hirsch said in a statement. "It is important to differentiate between the highly toxic PFAS such as PFOA and PFOS for which the EPA has set drinking water standards, versus less toxic PFAS in pesticides that help maintain food security," notes Doug Van Hoewyk, a toxicologist at Maine's Department of Agriculture, Conservation and Forestry. He added that concerns about food residue depend on the PFAS and the quantity. Nathan Donley, a senior scientist at the Center for Biological Diversity, also commented: "The data we have about the use of PFAS pesticides is already seven years old, and since there have been many new approvals during that time, those numbers are sure to underestimate the amount were using today."

Ozone Hole Ranked As 5th Smallest In More Than 30 Years

Par :BeauHD
25 novembre 2025 à 07:00
Scientists report that the Antarctic ozone hole in 2025 is the fifth-smallest since 1992, thanks largely to decades of global restrictions on ozone-depleting chemicals under the Montreal Protocol. ABC News reports: The ozone hole reached its greatest one-day extent for 2025 in early September, measuring 8.83 million square miles, about 30% smaller than the largest hole on record in 2006. NOAA and NASA scientists emphasize that recent findings show efforts to limit ozone-depleting chemical compounds can have a significant impact. The regulations are established by the Montreal Protocol, which went into effect in 1992. Subsequent amendments are driving the gradual recovery of the ozone layer, which remains on track to fully recover later this century as countries worldwide replace harmful substances with safer alternatives. For decades, chlorofluorocarbons (CFCs) and other ozone-depleting compounds were widely used in aerosol sprays, foams, air conditioners and refrigerators, causing significant reductions in ozone levels. Natural factors, such as temperature and atmospheric circulation, also influence ozone concentrations and are likely to have contributed to a smaller ozone hole this year, according to researchers. "This year's hole would have been more than one million square miles larger if there was still as much chlorine in the stratosphere as there was 25 years ago," said Paul Newman, a senior scientist at the University of Maryland system and longtime leader of NASA's ozone research team.

Hacker Conference Installed a Literal Antivirus Monitoring System

Par :BeauHD
25 novembre 2025 à 03:30
An anonymous reader quotes a report from Wired: Hacker conferences -- like all conventions -- are notorious for giving attendees a parting gift of mystery illness. To combat "con crud," New Zealand's premier hacker conference, Kawaiicon, quietly launched a real-time, room-by-room carbon dioxide monitoring system for attendees. To get the system up and running, event organizers installed DIY CO2 monitors throughout the Michael Fowler Centre venue before conference doors opened on November 6. Attendees were able to check a public online dashboard for clean air readings for session rooms, kids' areas, the front desk, and more, all before even showing up. "It's ALMOST like we are all nerds in a risk-based industry," the organizers wrote on the convention's website. "What they did is fantastic," Jeff Moss, founder of the Defcon and Black Hat security conferences, told WIRED. "CO2 is being used as an approximation for so many things, but there are no easy, inexpensive network monitoring solutions available. Kawaiicon building something to do this is the true spirit of hacking." [...] Kawaiicon's work began one month before the conference. In early October, organizers deployed a small fleet of 13 RGB Matrix Portal Room CO2 Monitors, an ambient carbon dioxide monitor DIY project adapted from US electronics and kit company Adafruit Industries. The monitors were connected to an Internet-accessible dashboard with live readings, daily highs and lows, and data history that showed attendees in-room CO2 trends. Kawaiicon tested its CO2 monitors in collaboration with researchers from the University of Otago's public health department. The Michael Fowler Centre is a spectacular blend of Scandinavian brutalism and interior woodwork designed to enhance sound and air, including two grand pou -- carved Mori totems -- next to the main entrance that rise through to the upper foyers. Its cathedral-like acoustics posed a challenge to Kawaiicon's air-hacking crew, which they solved by placing the RGB monitors in stereo. There were two on each level of the Main Auditorium (four total), two in the Renouf session space on level 1, plus monitors in the daycare and Kuracon (kids' hacker conference) areas. To top it off, monitors were placed in the Quiet Room, at the Registration Desk, and in the Green Room. Kawaiicon's attendees could quickly check the conditions before they arrived and decide how to protect themselves accordingly. At the event, WIRED observed attendees checking CO2 levels on their phones, masking and unmasking in different conference areas, and watching a display of all room readings on a dashboard at the registration desk. In each conference session room, small wall-mounted monitors displayed stoplight colors showing immediate conditions: green for safe, orange for risky, and red to show the room had high CO2 levels, the top level for risk. Colorful custom-made Kawaiicon posters by New Zealand artist Pepper Raccoon placed throughout the Michael Fowler Centre displayed a QR code, making the CO2 dashboard a tap away, no matter where they were at the conference. Resources, parts lists, and assembly guides can be found here.

They argue current arms treaties don't adequately cover these emerging tools and call for a new, proactive framework to prevent the weaponization of the human mind. The Guardian reports: Michael Crowley and Malcolm Dando, of Bradford University, are about to publish a book that they believe should be a wake-up call to the world. [...] The book, published by the Royal Society of Chemistry, explores how advances in neuroscience, pharmacology and artificial intelligence are coming together to create a new threat. "We are entering an era where the brain itself could become a battlefield," said Crowley. "The tools to manipulate the central nervous system -- to sedate, confuse or even coerce -- are becoming more precise, more accessible and more attractive to states." The book traces the fascinating, if appalling, history of state-sponsored research into central nervous system (CNS)-acting chemicals. [...] The academics argue that the ability exists to create much more "sophisticated and targeted" weapons that would once have been unimaginable. Dando said: "The same knowledge that helps us treat neurological disorders could be used to disrupt cognition, induce compliance, or even in the future turn people into unwitting agents." The threat is "real and growing" but there are gaps in international arms control treaties preventing it from being tackled effectively, they say. [...] The book makes the case for a new "holistic arms control" framework, rather than relying on existing arms control treaties. It sets out a number of practical steps that could be taken, including establishing a working group on CNS-acting and broader incapacitating agents. Other proposals concern training, monitoring and definitions. "We need to move from reactive to proactive governance," said Dando. Both men acknowledge that we are learning more about the brain and the central nervous system, which is good for humanity. They said they were not trying to stifle scientific progress and it was about preventing malign intent. Crowley said: "This is a wake-up call. We must act now to protect the integrity of science and the sanctity of the human mind."
