Phys.org / Open-source AI may aid climate and development but deepen inequality, experts warn
Open-source artificial intelligence is advancing faster than the world can govern it, and the consequences could reshape the future of sustainability, democracy and global development. In a new comment published in Nature ...
Medical Xpress / New treatment shows promise for patients with rare blood disorder
A new treatment that involves growing a patient's immune cells and then infusing them back into their body has shown promise for people with the rare blood disorder aplastic anemia. Results from the Phase 1 trial, led by ...
Phys.org / X-rays reveal how platinum oxidizes in real time inside hydrogen devices
Electrolysers produce hydrogen. Fuel cells, in turn, generate electricity from hydrogen. Both technologies are considered key building blocks of the energy transition, offering well-established solutions for storing, transporting ...
Phys.org / One storm pushed world's rarest great ape closer to extinction in Sumatra
Climate change-fueled landslides wiped out nearly one in 10 remaining members of the world's rarest great ape species on Indonesia's Sumatra island, scientists said Wednesday.
Phys.org / New cavity control strategy improves performance of blue vertical-cavity surface-emitting lasers
GaN-based vertical-cavity surface-emitting lasers (VCSELs) are promising for displays, sensing and optical communication, but improving efficiency remains challenging. Researchers have now shown that "cavity tuning," which ...
Phys.org / 'Cold insurance' for crops: Researchers unlock 'on-demand' climate resilience
Rapidly intensifying global climate instability is causing increasingly erratic temperature fluctuations. When sudden cold snaps strike during a crop's critical flowering window, they trigger irreversible pollen abortion, ...
Phys.org / Sharks, seals, hunters, tourists: How wildlife‑human interactions matter for conservation
Our relationships with wildlife are dynamic. They can change rapidly and unexpectedly.
Medical Xpress / How body clock may shape inflammation, cancer risk and timing of future treatments
Daily life is shaped by the solar day, influencing when we wake up, eat, work and sleep. Inside the body, a similar internal timing system—present in nearly every cell—known as the circadian clock synchronizes many biological ...
Phys.org / How ice-age sea-level falls may have turned seafloor volcanoes into ocean fertilizer
Ice-age sea-level declines may have turned seafloor volcanoes into natural iron fertilizer for plankton, potentially enhancing ocean carbon storage, Boston College researchers report in the journal Nature Geoscience.
Medical Xpress / First large-scale atlas of senescent cells could help inform future therapies for age-related diseases
A research consortium has established a new framework to identify and catalog senescent cells—cells that stop dividing but remain active in the body. Because senescent cells accumulate with age and are thought to contribute ...
Medical Xpress / AI-designed universal vaccine clears first human trial, targets future coronavirus threats with needle-free delivery
The first human clinical trial of a universal Sarbeco coronavirus vaccine, developed by the University of Cambridge and spin-out DIOSynVax (DVX) Ltd, has shown that the vaccine is safe and has no significant side effects.
Phys.org / Carbon dioxide removal slow to take off, alarming scientists
Carbon dioxide removal experts have sounded the alarm in Milan this week over a shortfall in research and investment in the nascent sector viewed as essential for mitigating climate change.
