Researchers applied mass spectrometry-based proteomics to analyze adhesives and glues found on a range of ancient Egyptian artifacts without damaging them, publishing their findings in Science Advances. Alongside expected animal collagens and egg proteins, they identified plant-derived proteins from sesame and moringa (drumstick tree) sources, expanding the known palette of binding materials used by ancient craftspeople.
Scientists at the Technical University of Denmark built a nanolaser small enough to potentially be embedded by the thousands on a single microchip, letting devices transmit data as light rather than electrical signals. The work, led by professor Jesper Mørk with colleagues Meng Xiong and Yi Yu, appeared in Science Advances.
Anthropic has disclosed that one of its AI models was linked to a fourth instance of likely criminal misuse, continuing a pattern of disclosures about how its systems can be exploited for harmful purposes. Details of the specific incident were not fully outlined in available reporting, but it adds to a growing list of documented misuse cases tied to the company's models.
A multiyear Harvard study led by psychologist Matthew K. Nock tracked over 600 high-risk adults and adolescents and successfully predicted 75 percent of suicide attempts and 87 percent of suicide-related events in the seven days before they happened. The findings, set to publish in the Journal of Psychopathology and Clinical Science, mark a sharp improvement over traditional models that forecast risk months or years out rather than days.
A Nature feature surveys six novel approaches under development for delivering drugs more precisely and effectively, ranging from advanced nanoparticle carriers to devices designed to target specific tissues. These innovations aim to overcome longstanding challenges such as poor bioavailability, degradation before reaching target sites, and off-target side effects.
A Nature retrospective highlights the scientific career of William Thomson, later Lord Kelvin, noting that his contributions extended well beyond the temperature scale that bears his name. The piece surveys his broader body of work in physics and engineering during the 19th century.
Chinese memory chipmaker CXMT told investors it is expanding its foothold in premium memory-chip segments, pointing to progress in smartphone and AI-related chip technologies as evidence. The company framed these advances as proof it is closing the gap with established global memory manufacturers.
A new study in AGU Advances models how a rare, extreme geomagnetic storm—similar in scale to the 1859 Carrington Event—would strain the modern US power grid. Researchers found the Northeast and Northern Plains, particularly higher-latitude areas, face the greatest risk of widespread grid failure, with total economic losses estimated at $1.5 to $2 billion per day.
Astronomers using the Hubble Space Telescope have identified a ten-sided cloud formation encircling Saturn's south pole, a counterpart to the long-known hexagon at the planet's north pole. The decagon, detailed in a new Science Advances study, has sides roughly 16,800 kilometers long and sits near a jet stream blowing close to 260 miles per hour, even though the shape itself drifts at less than 6 mph.
A California bill aimed at regulating surveillance-based pricing — where retailers use personal data to set individualized prices — failed to advance to Governor Newsom's desk before the legislative deadline. The California Retailers Association responded by expressing hope that lawmakers can restart negotiations next year by focusing on points of existing consensus.
Proofpoint, owned by private equity firm Thoma Bravo, is reportedly in advanced negotiations to acquire cybersecurity company Varonis Systems. News of the talks sent Varonis shares sharply higher, reflecting its roughly $5 billion market valuation.
Researchers examined a fragment of 'hiroshimaite,' fallout material from the 1945 Hiroshima atomic bombing, and identified a previously unknown alloy composed of seven elements. The discovery, imaged via scanning electron microscope, was published in Science Advances ahead of the bombing's 81st anniversary.
