OpenAI has fired three researchers, at least two of whom worked in safety research, for allegedly mishandling sensitive company information outside established procedures. A company spokesperson said the dismissals were not related to raising safety concerns but to policy violations involving access to sensitive data, including material tied to an external organisation that evaluates AI models.
Scientists studying Mars's chaotic terrain—regions of jumbled, collapsed mesas and deep depressions—say crater counts and geological analysis date these formations to between 2.0 and 3.8 billion years ago. The terrain is concentrated near ancient giant river valleys, and researchers have found water-related minerals such as hematite and phyllosilicates in these regions.
Apple TV has begun streaming "The Last First: Winter K2," a documentary directed by Amir Bar-Lev that holds a 100% Rotten Tomatoes score. The film covers a 2021 winter expedition to summit K2, centering on climbers John Snorri Sigurjónsson and the Sadpara father-son team, and had previously opened in select theaters.
Amazon unveiled two new Kindle accessories: a $34.99 Bluetooth remote called Kindle Click for turning pages and adjusting brightness without touching the screen, and a $79.99 magnetic cover with physical page-turn buttons for new Signature Edition Paperwhite and Colorsoft models. Both ship Oct. 28 alongside a refreshed Kindle lineup featuring flush screens, wraparound color, optional aluminum housings, and user-replaceable batteries to meet EU rules.
California Gov. Gavin Newsom signed Senate Bill 1246, requiring autonomous vehicle companies such as Tesla, Waymo and Zoox to provide local support when their robotaxis malfunction or interfere with emergency crews. Operators can face penalties if a vehicle blocks police or firefighters for more than 30 minutes, and the law sets new accountability rules for crashes, breakdowns or roadway obstructions.
Breakthrough T1D, a major diabetes nonprofit, dismissed three board members of its affiliated venture-capital arm, the T1D Fund. The nonprofit says the move was meant to safeguard donor interests, while the ousted members contend it undermined the fund's independence.
A developer built a system where AI language models, including Opus 5.5, produce paintings by writing programs that control a physics-based simulation of oil paint on linen, including bristle brushes, wet paint, drying and layered glazes. No image-generation model is used; most models paint in the style of Caspar David Friedrich based only on written research rather than seeing his actual artwork. Of 75 paintings produced, 46 were created incrementally at a simulated easel, with the model working passage by passage and periodically stepping back to assess progress.
Researchers described a complete fossil of Norellraptor barsboldi, a microraptorine dinosaur showing feather traces on its limbs and tail. The team found that flight-related adaptations seen in this group also appeared independently in the bird lineage Avialae, but developed in a different sequence. The findings were published in Nature Communications.
Researchers have developed a gene-editing approach that restricts edits to particular cells depending on their position or context within tissue, rather than editing indiscriminately. The technique aims to limit changes to only the intended cell population, reducing effects on surrounding cells.
Nature has released an interactive quiz asking readers to identify women who have won Nobel prizes in physics, chemistry and physiology or medicine. The feature accompanies the publication's broader look at the long-standing gender gap among science Nobel winners since the prizes began in 1901, and will be updated once this year's winners are announced.
Author Hernan Diaz spoke with Nature about his new novel 'Ply,' describing how studying physics shaped his worldview and influenced his writing. The interview, published on nature.com, explores the connection between scientific thinking and his literary work.
At the UN General Assembly in September, Panama's president José Raúl Mulino proposed a Universal Declaration of the Rights of Nature, which would recognize nature as a legal 'subject of rights' with intrinsic value. On 24 September, Panama, Tonga and Vanuatu launched the For Nature Coalition of States, joined by founding members Palau and Dominica, to build diplomatic support for the idea within the UN's Harmony with Nature process.
