A researchers' propensity for risky projects is passed down to their doctoral students -- and stays with trainees after they leave the laboratory, according to an analysis of thousands of current and former PhD students and their mentors. From a report: Science involves taking risks, and some of the most impactful discoveries require taking big bets. However, scientists and policymakers have raised concerns that the current academic system's emphasis on short-term outcomes encourages researchers to play it safe. Studies have shown, for example, that risky research is less likely to be funded. Anders Brostrom, an economist studying science policy at the University of Gothenburg in Sweden, and his colleagues decided to examine the role of doctoral education in shaping risk-related behaviour -- an area that Brostrom says has been largely overlooked. "We often focus on thinking about how we can change the funding systems to make it more likely for people to take risks, but that's not the only lever we have," says Chiara Franzoni, an economist at the Polytechnic University of Milan in Italy. This study is "refreshing" because "we've discussed policy interventions a lot, but we haven't discussed training," she adds. [...] The team found that students' risk-taking dispositions matched those of their supervisors. This link was stronger when students and their supervisors communicated frequently, and weaker when students were also mentored by scientists outside their lab.

An anonymous reader shares a report: A hit song has been excluded from Sweden's official chart after it emerged the "artist" behind it was an AI creation. I Know, You're Not Mine -- or Jag Vet, Du Ar Inte Min in Swedish -- by a singer called Jacub has been a streaming success in Sweden, topping the Spotify rankings. However, the Swedish music trade body has excluded the song from the official chart after learning it was AI-generated. "Jacub's track has been excluded from Sweden's official chart, Sverigetopplistan, which is compiled by IFPI Sweden. While the song appears on Spotify's own charts, it does not qualify for inclusion on the official chart under the current rules," said an IFPI Sweden spokesperson. Ludvig Werber, IFPI Sweden's chief executive, said: "Our rule is that if it is a song that is mainly AI-generated, it does not have the right to be on the top list."

OpenAI said Friday that it will begin testing ads on ChatGPT in the coming weeks, as the $500 billion startup seeks new revenue streams to fund its continued expansion and compete against rivals Google and Anthropic. The company had previously resisted embedding ads into its chatbot, citing concerns that doing so could undermine the trustworthiness and objectivity of responses. The ads will appear at the bottom of ChatGPT answers on the free tier and the $8-per-month ChatGPT Go subscription in the U.S., showing only when relevant to the user's query. Pro, Business, and Enterprise subscriptions will remain ad-free. OpenAI expects to generate "low billions" of dollars from advertising in 2026, FT reported, and more in subsequent years. The revenue is intended to help fund roughly $1.4 trillion in computing commitments over the next decade. The company said it will not show ads to users under 18 or near sensitive topics like health, mental health, or politics.

Seattle was late to the light rail party -- the city rejected transit ballot measures in 1968 and 1971, missing out on federal funding that built Atlanta's MARTA, and didn't approve a plan including rail until 1996 -- but the Pacific Northwest city is now in the middle of a multibillion-dollar building boom that has produced the highest post-pandemic ridership recovery of any US light rail system. The Link system opened its first line in 2009, funded largely by voter-approved tax measures from 2008 and 2016. The north-south 1 Line now stretches 41 miles after a $3 billion extension to Lynnwood opened in June 2025 and a $2.5 billion leg to Federal Way debuted in December. Ridership is up 24% since 2019, and 3.4 million people rode Link trains in October 2025. Test trains have been running since September across the I-90 floating bridge over Lake Washington -- what Sound Transit claims is the world's first light rail on a floating structure -- preparing for a May 31 opening. The Crosslake Connection is part of the 2 Line, a 14-mile, $3.7 billion extension voters approved in 2008 that was originally slated to open in 2020. The expansion hasn't come without problems. Sound Transit faces a roughly $30 billion budget shortfall, and a planned Ballard extension has ballooned to $22 billion, double original estimates.

An anonymous reader quotes a report from the Guardian: Screen time spent gaming or on social media does not cause mental health problems in teenagers, according to a large-scale study. [...] Researchers at the University of Manchester followed 25,000 11- to 14-year-olds over three school years, tracking their self-reported social media habits, gaming frequency and emotional difficulties to find out whether technology use genuinely predicted later mental health difficulties. Participants were asked how much time on a normal weekday in term time they spent on TikTok, Instagram, Snapchat and other social media, or gaming. They were also asked questions about their feelings, mood and wider mental health. The study found no evidence for boys or girls that heavier social media use or more frequent gaming increased teenagers' symptoms of anxiety or depression over the following year. Increases in girls' and boys' social media use from year 8 to year 9 and from year 9 to year 10 had zero detrimental impact on their mental health the following year, the authors found. More time spent gaming also had a zero negative effect on pupils' mental health. "We know families are worried, but our results do not support the idea that simply spending time on social media or gaming leads to mental health problems -- the story is far more complex than that," said the lead author Dr Qiqi Cheng. The research, published in the Journal of Public Health, also examined whether how pupils use social media makes a difference, with participants asked how much time spent chatting with others, posting stories, pictures and videos, browsing feeds, profiles or scrolling through photos and stories. The scientists found that actively chatting on social media or passive scrolling feeds did not appear to drive mental health difficulties. The authors stressed that the findings did not mean online experiences were harmless. Hurtful messages, online pressures and extreme content could have detrimental effects on wellbeing, but focusing on screen time alone was not helpful, they said.

Amazon is expanding the Fallout universe with Fallout Shelter, a ten-episode reality competition show where contestants face survival-style challenges and moral dilemmas for a cash prize. Engadget reports: Prime Video has greenlit a unscripted reality show titled Fallout Shelter. It will be a ten-episode run with Studio Lambert, the team behind reality projects including Squid Game: The Challenge and The Traitors, as its primary producer. Bethesda Game Studios' head honcho Todd Howard is attached as an executive producer. Amazon's description of Fallout Shelter is: "Across a series of escalating challenges, strategic dilemmas and moral crossroads, contestants must prove their ingenuity, teamwork and resilience as they compete for safety, power and ultimately a huge cash prize." [...] The name echos the free-to-play mobile game Bethesda released in 2015. Fallout Shelter lets people build and improve their out Vault-Tec residence, managing the resources for a growing cadre of underground survivors. It seems pretty likely that there will be some type of tie-in between the game and the show, but any details about that might pop up closer to when the program is ready to air. It's currently casting, and no release timeline has been shared.

New York Governor Kathy Hochul is proposing first-of-its-kind legislation that would require 3D printers sold in the state to include built-in software designed to block the printing of gun parts used to make "ghost guns." The plan would also add criminal penalties for making 3D-printed firearms and hold printer owners or manufacturers liable if safety controls aren't in place. 3D Printing Industry reports: "From the iron pipeline to the plastic pipeline, these proposals will keep illegal ghost guns off of New York streets, and enhance measures to track and block the production of dangerous and illegal firearms in our state," Hochul said. In addition to mandating printer-level safeguards and restricting access to CAD files, the proposed legislation would require law enforcement agencies to report any recovered 3D printed firearms to a statewide database. The measure also includes a provision requiring commercial gun manufacturers to redesign pistols so they cannot be easily converted for automatic fire. "These illegal firearms are being manufactured in homes and used in crimes right now, which is why I have been working with my colleagues in Albany and the private sector over the past several years to stop their proliferation. Passing these measures will reduce crime and strengthen public safety for all New Yorkers," said Manhattan District Attorney Alvin Bragg.
