Tech Xplore / New federated learning algorithm enables private, robust, and fast AI development
Three heads are better than one. Versions of this proverb are found worldwide and throughout history. Yet in the race to achieve artificial general intelligence, engineers have centralized AI development and training to accelerate ...
Medical Xpress / Medicare prescriptions for Wegovy jumped after approval for heart disease
Medicare prescriptions for Wegovy increased sharply after the program started covering the anti-obesity medication to prevent heart problems, but just a fraction of beneficiaries likely eligible received the treatment, according ...
Phys.org / One in four managers withholds feedback from those they supervise, even when the news is positive
Performance feedback is critical for supporting career and education decisions, but in a new study published in Management Science, a research team from the University of Portsmouth, the University of Exeter and York University ...
Medical Xpress / Evidence reveals that the language of thought is not natural language
Some people find it useful to talk through their problems—but language isn't necessary for logical reasoning, cognitive neuroscientists at MIT's McGovern Institute for Brain Research say.
Phys.org / Next‑generation membranes can refine crude oil using under half the energy of distillation
Oil refining is necessary for transforming raw, unusable crude oil into valuable goods like gasoline, diesel, jet fuel and petrochemical feedstocks. However, the usual distillation process is energy-intensive, spurring researchers ...
Phys.org / Heat waves push tropical forests past photosynthesis limits across 57 million hectares
As heat waves continue one after another, we are feeling their effects on our own bodies: It becomes harder for us to function normally. Trees also have their limits when temperatures are too high. Above a certain critical ...
Medical Xpress / Hidden pathway drives COVID-19 infection, triggers damaging inflammation in the lungs
New research has uncovered a hidden pathway that allows COVID-19 to infect the immune system and trigger damaging inflammation in the lungs. The study by La Trobe University and WEHI researchers found SARS-CoV-2, the virus ...
Phys.org / Fossils found decades ago reveal extinct 3.5 million-year-old giant salamander species
In the late 1990s in the Ajimu region of Japan's Oita Prefecture, researchers discovered three fossilized vertebrae belonging to the Cryptobranchidae family of giant salamanders. These were embedded in the Tsubusugawa Formation, ...
Tech Xplore / AI agent tests whether machines can speak for patients at life's end
Across aging societies, a gap is widening: People live longer, but families grow smaller. A rising number could reach the end of life, unable to make their own medical decisions and with no next of kin or trusted friend to ...
Medical Xpress / Softening aging ovaries could help extend fertility as women get older
Fertility declines as women get older for many reasons, such as a drop in egg quality, decreased follicle numbers and hardening of ovarian tissues. That's a problem for would-be mothers in many countries who prefer to have ...
Phys.org / Fish DNA and 10,000 crystals rewrite Colorado River's Grand Canyon origin story
For more than 150 years, scientists have debated when and how the Colorado River first carved its way through the Grand Canyon. Now, a new study led by researchers at the University of New Mexico offers evidence that the ...
Medical Xpress / Medical AI may look less biased on paper but not in practice, new study finds
Large language models (LLMs) are only as good as the data they learn from. If their training data contains social biases, the models may unintentionally repeat those biases in their responses. As their use increases with ...
