Phys.org / Tooth fossil analysis suggests 'brawn before bite' in early Asian mammals
An analysis of fossil teeth from mammals that lived in China following the most recent major mass extinction suggests size came before both shape and function as diets diversified.
Phys.org / One‑step process generates high entropy alloy nanoparticles in milliseconds for catalyst creation
A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could accelerate the discovery of new materials for energy and electronic applications. The study, published ...
Medical Xpress / Billions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
A sweeping global review led by researchers at the University of British Columbia has found that mRNA vaccines—now administered billions of times worldwide—are safe and highly effective at preventing infectious diseases like ...
Phys.org / Wildfires rage in southern France, 3,000 people evacuated
Nearly 3,000 people have been evacuated in southwestern France as Prime Minister Sebastien Lecornu sounded the alarm over an early outbreak of wildfires in the wake of a record-breaking heat wave.
Phys.org / World's largest particle smasher halts for upgrade to boost hunt for dark matter
The world's most powerful particle accelerator will shutter operations Monday for four years of renovations to dramatically boost its collision capacity and the potential for unlocking one of the greatest mysteries of the ...
Medical Xpress / A portable ultrasound system could make reliable breast imaging more accessible
For people at high risk of developing breast cancer, yearly mammograms may not be enough to detect tumors early. To make earlier diagnosis easier, an MIT team has developed portable detectors based on ultrasound, which could ...
Tech Xplore / Aquifer 'thermal batteries' may cut AI data center cooling demand and save water
Aquifer-based geothermal systems, known as aquifer thermal energy storage, could help ease the environmental stress stemming from artificial intelligence data centers in the United States. Researchers at the Prairie Research ...
Phys.org / Hantaviruses may have co-evolved with rodents for ages, helping explain silent spread
What does a hantavirus do inside its rodent hosts? How do these viruses move through animal populations? And how is it that they cause almost no apparent symptoms in rodents, yet can be nearly fatal in humans? Specially Appointed ...
Phys.org / Sound waves reconstruct Alaska fireball path after cameras miss key details
When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something ...
Phys.org / One amino acid may signal the 'point of no return' in dying leaves
Before a leaf dies, plants recover nutrients that the rest of the plant can reuse for growth and survival. Researchers at Umeå Plant Science Center have now identified a metabolic "point of no return" linked to the amino ...
Medical Xpress / Researcher investigates enthusiasm as a distinct psychological emotion
Enthusiasm receives little attention in psychology. PhD researcher Rijn Vogelaar aims to change that. His doctoral dissertation research shows that enthusiasm is a distinct emotion that not only gives people energy, but also ...
Phys.org / How boundary geometry helps embryonic cells organize themselves
One of the most striking biological transitions in nature happens early in development, when an embryo transforms from a simple ball of cells into a highly ordered structure with distinct tissue layers that later develop ...
