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 / History, not age, determines the genomic importance of ancient trees
Ancient trees—those that are remarkably old for their species—are declining worldwide, raising concerns about the loss of the ecological and evolutionary history they represent. Their exceptional longevity has long encouraged ...
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 / Hybrid bioprinter creates capillary networks narrower than 10 micrometers
More than 100,000 people are awaiting an organ transplant in the United States, with a new candidate added to the list every 10 minutes. Even if the transplant is carried out successfully, recipients must take immunosuppressive ...
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 / Californians are twice as likely as Louisianans to be childfree—but demographics tell more of the story
Across the United States, the number of people who do not have and do not want to have children is growing. While they are twice as likely to live in California as Louisiana, individual demographic characteristics are the ...
Phys.org / Mirage or miracle? JWST finds earliest known 'black hole star' at cosmic dawn
Little red dots have puzzled astronomers since their discovery in James Webb Space Telescope (JWST) data from the universe's deep past. Their "powering engines" might resemble a newly discovered phenomenon dubbed a "black ...
Phys.org / Spontaneous magnons synchronize with external signals at room temperature
Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient ...
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 / 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 / Immune 'reprogramming' could protect poultry from deadly diseases without antibiotics
University of Bristol–led researchers have identified a naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections. This development, published today, Aug. ...
Phys.org / 20-year study finds pre-K impacts a child's academic future
Students who attended public school pre-K performed better academically through high school than those in family-based child care, according to new research from Florida International University.
