Phys.org / AI tool could help veterinarians track heart disease more precisely
For dogs with heart disease, a fraction of a centimeter can make a life-changing difference. Veterinarians often rely on chest radiographs to monitor subtle changes in heart size that help determine when treatment should ...
Phys.org / Chemical fingerprints reveal hidden binary pasts of massive stars
More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether through mass transfer, ...
Phys.org / Rangers and scientists map vulnerable reefs in the remote Groote Archipelago
For thousands of years, the Anindilyakwa people have lived in deep connection with the waters surrounding Groote Eylandt, a remote island in the Gulf of Carpentaria.
Phys.org / Radiation vest tested on NASA moonshot can cut astronauts' exposure in solar storms, study suggests
A new study suggests a protective vest tested on a manikin during NASA's first Artemis moonshot could drastically cut the radiation exposure of lunar astronauts during severe solar storms.
Phys.org / Wars between nations face persistent escalation risk, decades of conflict data suggest
Military leaders frequently underestimate how big the wars they engage in will get. Gen. Douglas MacArthur predicted U.S. troops could come home from the Korean War in time for Christmas, just months after the conflict started. ...
Phys.org / Bumblebees can learn to associate new smells with their queen
Bumblebees are able to learn to associate new odors with their colony's queen, instead of being preprogrammed to recognize the queen's pheromones from birth, according to a new study led by researchers at Penn State. For ...
Phys.org / Oxytocin nudges distrustful men to invest 15% more in anonymous trust game
In 2005, a research team led by University of Zurich economics professor Ernst Fehr published a study in the journal Nature that provided evidence for the first time that intranasally administered oxytocin can increase trusting ...
Phys.org / Mathematical model shows how birds create a synchronized dawn chorus
Every morning, groups of birds start singing and chirping around the same time, typically when the sun starts rising. While zoologists have been studying this collective bird behavior, called the dawn chorus, for decades, ...
Phys.org / Genome study reveals centromeres as one of the fastest-changing regions in human DNA
A centromere is a specific region on a chromosome that ensures that, when a cell divides, the chromosome separates accurately so each new cell receives the correct amount of genetic material. Despite their essential role, ...
Phys.org / Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...
Phys.org / First evidence of Neanderthal bone tool use in Romania discovered
Deep in the Vârghiș Gorges, tucked away in the dark recesses of a cave, researchers have found the first evidence that Neanderthals used bone tools in Romania.
Phys.org / Many US public parks sit surprisingly close to hazardous waste sites and facilities that release toxic chemicals
While parks, playgrounds and hiking trails are generally thought of as "healthy" spaces, researchers from the University of Michigan have found that many of them overlap with old toxic waste sites or sit dangerously close ...
