Phys.org / Saber-toothed cats' spinal tumors suggest inbred species struggled to survive
The fossilized spines of saber-toothed cats in the La Brea Tar Pits reveal evidence of an unexpectedly high prevalence of rare spinal nerve tumors, suggesting that the species became inbred just before extinction. These tumors, ...
Medical Xpress / U.S. poll reveals many young adults may not be ready to manage their own health care
Many young adults may be entering adulthood without the practical skills needed to manage their own health care, suggests a new national poll. Nearly 1 in 6 parents said their young adult child, ages 18–25, doesn't handle ...
Medical Xpress / Emergency physician burnout: 1 in 10 leaving specialty in Canada
Burnout is pushing emergency physicians to leave the specialty or reduce clinical hours, adding to the body of research pointing to a crisis in health care in Canada, according to a new study published in CMAJ (Canadian Medical ...
Medical Xpress / Working memory rapidly updates its priorities after distractions, study finds
When humans tackle many everyday tasks, ranging from driving to completing household chores and work assignments, they rely heavily on working memory. This is the brain's ability to temporarily store and manipulate important ...
Phys.org / A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
Phys.org / Gamma-ray pulsations reveal extreme 3.2-millisecond pulsar 3,900 light-years away
By analyzing the data from NASA's Fermi gamma-ray space telescope, Chinese astronomers have investigated a recently identified millisecond pulsar known as PSR J0435+3233. As a result, they found that the pulsar exhibits gamma-ray ...
Phys.org / Angola's oldest burials, including its only known ancient cremation, uncovered at a 15th-century site doomed by a dam
As the construction of a hydroelectric dam loomed, archaeologists raced to uncover Angola's earliest dated burials and its only known cremation at a 15th-century settlement before it vanished beneath the water.
Dialog / Near a black hole, gravity changes a quantum circuit's readings, not its rules
Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...
Phys.org / Tigray's old grapevines have survived against the odds: New research uncovers their genetic and historic value
The northern highlands of Ethiopia are among Africa's oldest agricultural landscapes. Some of the world's most important crops originated here, particularly pulses and grains, including teff. Yet another crop has a less well-known ...
Medical Xpress / Kids do feel the cold, so why won't they wear a sweater?
It happens just when you need to leave. Bags are packed. Shoes are on. Then your child decides a sweater is impossible. You say, "Put your sweater on." They say, "I'm not cold." Do kids really not feel the cold like adults ...
Phys.org / Twisted laser light distinguishes mirror-image molecules by their fragment counts
Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers ...
Tech Xplore / 3D-printable material can heal the body, build better robots and recover critical minerals
A new type of 3D-printable material developed by researchers at The University of Texas at Austin mimics human tissue's ability to sort and filter, allowing certain molecules to pass through while keeping others out. This ...
