A Nature Briefing Chat episode examines the widely taught story about the Bunsen burner's origins and finds the popular version doesn't hold up to scrutiny. The discussion revisits the historical record to clarify who actually contributed to the device's development and how the myth took hold.
A preprint analyzing nearly 900 recipients of NIH K career-development awards found that successful early-career researchers typically had a median of three mentors, with some reporting as many as 15. These mentors served distinct functions: research mentors mainly helped with publications and grant writing, while other mentors provided professional introductions, skill-building, or emotional support.
Researchers led by psychologist Tobias Brosch at the University of Geneva analyzed 71 studies covering over 216,000 participants to compare climate-communication strategies. Published in the Journal of Environmental Psychology, the review found that messages evoking awe, wonder or hope were more effective at motivating climate-friendly behavior than purely scientific fact-based appeals, while messages emphasizing personal responsibility often failed or backfired.
Chinese pharmaceutical companies, once known mainly for producing cheap generic medicines, are now developing original obesity and weight-loss drugs aimed at competing with Western blockbusters like Ozempic and Wegovy. Several firms are advancing candidates through clinical trials and striking licensing deals with major international drugmakers.
An amateur vacuum tube maker built a second diode tube specifically to document the process for a Make: Magazine article after his original tube, made hastily before Hackaday Superconference 2022, lacked good process photos. The piece, published in Make: Volume 86, details the tricky pinch-seal technique using Tungsten wire welded to Nickel pins and coated with oxide to bond glass and metal in a vacuum-tight seal.
OpenAI has privately pressed members of Congress for guidance on whether AI labs could legally coordinate to slow the pace of frontier AI development without violating antitrust law. The inquiry follows a blog post from chief scientist Jakub Pachocki calling for industry-wide coordination on safety, including voluntary slowdowns until shared safety standards emerge. Legal experts warn that such coordination could be seen as restricting output under the Sherman Antitrust Act, creating uncertainty that discourages collaboration.
System76 has introduced Thelio Mira AI, a Linux-based desktop workstation aimed at local AI development that supports GPU configurations offering up to 192 GB of memory. The machine is designed to let developers train, fine-tune, and iterate on demanding AI models without relying on cloud infrastructure, and it ships with standard System76 hardware warranty options of one, two, or three years.
Dutch companies LeydenJar and Powall are not manufacturing complete batteries but specializing in critical components, such as battery anodes, aiming to secure a strategic foothold in the global battery supply chain. LeydenJar's Christian Rood likens this approach to ASML's dominance in semiconductor equipment, where being indispensable in one production step grants outsized influence over an entire industry.
Apple's Audio Intelligence suite on the Watch Series 12 introduces Live Rewind, which captures the last 15 seconds of nearby audio via a double-press of the Digital Crown, transcribes it on a paired iPhone, and discards the raw audio. A companion feature, Siri Recap, generates AI-written summaries of conversations heard throughout the day. Apple says an audible chime and on-screen animation alert people nearby, but does not obtain explicit consent from every speaker captured.
A comparison of the flagship-sized iPhone 18 Pro Max and Galaxy S26 Ultra shows both share a 6.9-inch screen but differ in build: Apple mixes aluminum and glass while Samsung uses an all-glass back. Samsung's phone is lighter and thinner, has a marginally higher-resolution AMOLED display, and retains the S Pen stylus, while Apple's OLED screen edges ahead on peak brightness at 3,000 nits versus 2,600 nits.
Governor Gavin Newsom signed more than a dozen bills into law on Thursday aimed at protecting minors online. The measures target addictive design features on social media platforms and impose new restrictions on AI-driven chatbots that interact with children.
Apple introduced the AirPods 5 with a wireless charging case at its recent event, pricing them roughly $30 below the ANC-equipped AirPods 4. Hands-on impressions suggest the newer earbuds outperform their predecessor across the board despite the lower cost.
