Prince William and the Duchess of Cambridge launched the Earthshot Prize, a decade-long initiative to fund solutions for pressing environmental issues by 2030. The project will award five winners annually for ten years, aiming to generate at least 50 breakthroughs. Sir David Attenborough has called it the most prestigious environmental award in history.
Researchers are adapting carbon nanotube fibers, originally designed for aircraft wiring, for use in cardiac devices. These soft, highly conductive threads could reduce scar tissue formation and potentially transform treatment for sudden cardiac death. Human trials are expected to begin within a few years.
During a two-day French army exercise, a Boston Dynamics Spot robot used for reconnaissance ran out of battery and had to be carried by soldiers. The incident highlights the practical limits of military robotics and raises questions about oversight as the company learns of the deployment after the fact.
Scientists have unearthed 300,000-year-old Homo sapiens remains in Morocco, pushing back the origins of our species by over 100,000 years. The discovery at Jebel Irhoud challenges the long-held view that humanity emerged solely in East Africa, suggesting a more complex, continent-wide evolution.
Researchers using a high-speed electron microscope have observed dark points within light waves that move faster than light, confirming a 1978 theory. These massless vortices don't violate relativity, and the technique could reveal hidden nanoscale processes.
The Pentagon has released hazard reports detailing the size, shape, and color of unidentified aerial phenomena encountered by Navy pilots in 2013 and 2014. The reports note the objects could be drones but no operators were found, and follow the official release of three Navy videos last month.
A new study reveals that increased snowfall in East Antarctica could reduce ice melt and potentially slow sea level rise. However, scientists caution that this effect is part of a complex balancing act, and other factors may exacerbate the problem.
Researchers from the University of Colorado Anschutz Medical Campus and University College London have developed a new theory of molecular evolution using statistical mechanics. The model reveals that amino acid interactions and entrenchment drive evolutionary rates, potentially solving long-standing puzzles in reconstructing major evolutionary events.
Northrop Grumman has unveiled a full-scale prototype of the Manta Ray, an autonomous underwater vehicle developed for DARPA. The glider-like drone can operate independently for long durations, potentially anchoring to the seafloor to conserve power. Its exact mission remains classified, with speculation ranging from surveillance to payload delivery.
A study of Swedish consumers reveals that men's spending habits produce 16% more carbon emissions than women's, despite only a 2% difference in total expenditure. The gap is driven by higher spending on fuel and meat, suggesting targeted policy opportunities.
NVBOTS, a Boston-based startup, has developed a 3D printing method that uses 21 different metals in a single job, potentially disrupting traditional metal casting. The technology, still in development, offers precision and cost advantages for small, high-value parts, with industrial partner trials planned later this year.
Quantum teleportation, once a staple of science fiction, is being explored through quantum entanglement, where particles are linked regardless of distance. Scientists have already teleported a single photon or electron about 100 kilometers, though scaling up remains a challenge. Recent experiments with the Zeno effect offer a new avenue for transmitting information without entanglement.
Physicists in Barcelona have developed a floating glass bead, just a few hundred nanometers wide, that can measure individual molecules with high precision. The team believes this tabletop device could detect high-frequency gravitational waves and dark matter, offering a compact alternative to kilometer-scale detectors.
Recent reports indicate that large language models are hitting a performance ceiling, with diminishing returns from scaling up. Cognitive scientist Gary Marcus warns that the financial bubble could burst as investors realize that AGI is not imminent. Meanwhile, researchers are exploring new techniques like test-time compute to overcome these limits.
Rosie Campbell, a safety researcher at OpenAI, resigned, citing discomfort with recent shifts and the dissolution of the AGI Readiness team after Miles Brundage's exit. Her departure adds to a wave of exits amid concerns about the company's safety focus and commercial trajectory.
A new report reveals that AI-generated racist images are fueling anti-immigrant protests in the UK, with such posts gaining significantly higher engagement than organic content. Researchers warn these fabricated visuals can incite violence by framing white men as defenders, amid a surge in hate crimes.
Character.AI has quietly barred users under 18 from interacting with chatbots modeled on real celebrities and fictional fandom characters, a move that follows two lawsuits alleging harm to minors. The restriction, confirmed through platform testing, does not apply to adult accounts, and the company has not introduced age verification.
A forensic study commissioned by NPR and conducted by Arizona State University researchers found that ChatGPT's 'Sky' voice closely resembles Scarlett Johansson's, ranking higher than 98% of 600 actresses.
