Medical Xpress / Arthritis origins may begin before birth
Researchers at the Kennedy Institute have discovered that some joints may be more susceptible to inflammatory arthritis before birth, offering new insight into why rheumatoid arthritis attacks particular joints while sparing ...
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 / 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 / Drug-carrying nanoparticles shrink venous malformations by 70% in mice
Venous malformations are abnormally shaped veins that develop when the cells lining blood vessels grow too fast when they aren't supposed to. Children can be born with them, and as the child grows, the venous malformations ...
Phys.org / The impact of recent super El Niños on sea level rise
El Niños and La Niñas are the third-most dominant influences on Earth's climate, after the sun and the greenhouse effect. But they haven't been easy to decipher or to predict in terms of when they will happen and what exact ...
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 / 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 / Stellar stream beyond Milky Way offers new tool to map dark matter
In the image above, a faint trail of stars can be seen stretching across the galaxy. These structures, known as globular cluster stellar streams, are coherent stellar structures that retain a record of their dynamical history ...
Phys.org / Microbes turn CO₂ into protein and vitamin B9 at commercially viable prices
Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing ...
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 / African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising ...
