Phys.org / Gentle chemical glow helps scientists capture sharper images of living cells
We reach for brighter, better lighting for sharper pictures, whether we're photographing a puppy or a microscopic cell. In most cases, the light comes from outside the object being photographed. A recent study explored a ...
Phys.org / Turning a quantum battery's environmental sensitivity into an advantage
Quantum batteries, devices that store energy by exploiting quantum mechanical phenomena, could, in principle, be charged faster and more efficiently than classical ones. Despite their potential, connecting these batteries ...
Phys.org / Male Neanderthal pelvises resemble those of modern females, challenging decades-old assumptions
A new study by the Department of Anatomy and Anthropology at Tel Aviv University, published in Scientific Reports, offers an explanation for one of the striking differences between men and women: the evolutionary development ...
Phys.org / Astronomers catch hot birth of galaxy cluster more than 11 billion light-years away
Astronomers have detected an enormous cloud of gas tens of millions of degrees hot surrounding one of the most extreme structures known in the early universe. The study offers one of the clearest views yet of a galaxy cluster ...
Medical Xpress / Psychedelic exposure during adolescence disrupts a brain circuit linked to lasting social avoidance in rats
Psychedelics, drugs that alter people's perceptions, mood and thoughts, have recently shown promise for the treatment of some psychiatric disorders. Yet many psychedelic drugs remain controlled substances in most countries ...
Phys.org / Shrews exhibit reversible size changes in their skulls and noses to get through the winter
Scientists had previously observed that some species of shrews undergo a form of biological plasticity in which their bodies, skulls, brains and some organs shrink in the winter, then regrow in the spring. Now, a new study ...
Medical Xpress / Experimental drug shows promise in reversing high blood pressure's toll on kidneys and heart in mice
High blood pressure affects nearly 1 in 8 people worldwide, and its impact goes far beyond a number on a blood pressure monitor. It can quietly damage the heart, kidneys and brain, making it one of the world's biggest preventable ...
Medical Xpress / Compound produced after eating pomegranates targets stiff-heart failure pathway, early tests suggest
A compound produced in the body after eating pomegranates improves heart function by up to 80% in a type of heart failure with limited treatment options.
Medical Xpress / AI-calculated brain age predicts dementia risk years before doctors can see it
Memory clinics still rely on visual rating scales to assess brain atrophy, yet these tools lack the sensitivity to catch subtle changes associated with early dementia. A measure of how old a person's brain appears on brain ...
Medical Xpress / High-dose vitamin D may improve cognition among those at risk of dementia, study finds
With more than 7 million Americans living with Alzheimer's dementia—a number projected to reach nearly 13 million by 2050—new Emory University research suggests that higher vitamin D supplement intake may be associated with ...
Phys.org / AI agents coordinate behavior based on majority opinion—even when said opinions are meaningless
A new study published in Science Advances takes a closer look at how AI agents' choices are influenced by their peers. The team found that more advanced models tend to follow the majority when shown other agents' choices, ...
Phys.org / Lost 'mega-escarpment' across ancient USA may explain Grand Canyon's missing billion years
Scientists have found evidence that a colossal cliff stretching thousands of kilometers across ancient North America may have exposed the heart of the Grand Canyon nearly a billion years before it was carved by the Colorado ...
