Phys.org / A dying star offers a rare glimpse of how the universe recycles its raw materials
Astronomers have captured an unprecedented image of a cosmic recycling project in progress—fragments of a dying star being busted up, stripped and absorbed into interstellar space.
Medical Xpress / In vivo CRISPR screen identifies gene edits that strengthen CAR-T therapy against solid tumors
For patients with blood cancers like leukemia and lymphoma, the immunotherapy known as CAR-T cell therapy can be lifesaving. Doctors remove a patient's immune cells, called T cells, engineer them in the lab to better recognize ...
Medical Xpress / Brain inflammation may cast a long dementia shadow in older survivors of encephalitis
Encephalitis is a serious condition in which an infection or autoimmune response triggers inflammation of the brain. The resulting swelling can disrupt normal brain function, causing neurological changes such as confusion, ...
Phys.org / Unsupervised free time increases the likelihood that adolescents will engage in violent behavior, 21-country study finds
A study involving more than 58,000 adolescents from 21 countries found that "unstructured free time"—defined as periods without adult supervision or activities guided by educational, cultural or athletic goals—is strongly ...
Phys.org / Severe weather now a key predictor of where bird species occur in North America
Scorching heat waves, severe cold snaps and other extreme weather events are limiting where species can exist—and affecting biodiversity estimates—for more than 500 North American bird species, according to a new, Yale–led ...
Phys.org / Unfamiliar with rattlesnakes, blackbirds still avoid striking them while defending nests
In a rare study of snakes as nest predators, scientists found nesting birds were loath to strike rattlesnakes even though they likely had no previous experience with vipers.
Phys.org / Europe's worst medieval flood highlights risk of successive extreme events
New research involving the University of Liverpool has provided comprehensive insights into the largest flood event in Europe over the past millennium—the flood traditionally known as "St. Mary Magdalene's Flood" of 1342.
Phys.org / New evidence helps solve how earliest birds took flight
The first bird to inhabit Earth used its robust hind legs to make two or three powerful leaps while flapping its way to flight, according to a study by the University of Southampton published in Developmental Biology.
Phys.org / Graphene nanowrinkles could reshape electricity in future ultrathin devices
Rice University researchers have shown that tiny wrinkles in graphene can change the material's electrical properties, providing evidence for flexoelectricity, a phenomenon in which a material generates an electric charge ...
Medical Xpress / Taking the stairs could cut risk of early death
Taking the stairs could help you live longer—according to new research from the University of East Anglia and the Norfolk and Norwich University Hospital. The study, published today, suggests that climbing stairs significantly ...
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 / 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, ...
