Researchers develop online training module to counteract the negative effects of stress on adolescents

Mon, 2022-08-22 10:59
Adolescents are showing record levels of anxiety, depression and stress. A team of researchers working on a project made possible by two grants from the U.S. National Science Foundation has developed a 30-minute online training module that teaches…

New research uncovers the internal structure of spider silk

Mon, 2022-08-22 10:58
Scientists at William & Mary funded by the U.S. National Science Foundation studied spider silk in such detail they were able to determine the structure of the silk fibers. Spider silk is known for its strength and durability. "Scientists all over…

Legacy of ancient ice ages shapes how seagrasses respond to environmental threats today

Thu, 2022-08-18 10:03
Deep evolution casts a longer shadow than previously thought, scientists report in a paper published in Proceedings of the National Academy of Sciences. U.S. National Science Foundation-supported scientists looked at eelgrass communities — the…

Smoke from Western wildfires can influence Arctic sea ice, researchers find

Thu, 2022-08-18 10:02
Sea ice and wildfires may be more interconnected than previously thought, according to U.S. National Science Foundation-supported research published in Science Advances. By digging into the differences between climate models, researchers at the…

Interaction between humans and the environment is focus of 15 new NSF-funded projects

Wed, 2022-08-17 12:59
From Southwestern deserts to tropical mangrove reefs, everywhere humans live or go we impact the environment, and the environment impacts us. Fifteen new projects totaling more than $21.6 million funded by the U.S. National Science Foundation will…

Physicists research how aerosol particulates from wind instruments move through the air

Wed, 2022-08-17 10:31
Researchers at the University of Pennsylvania supported by two grants from the U.S. National Science Foundation have studied the aerosols of musicians playing wind instruments. The findings will inform safety guidelines for not only musical…

Rare plants attract rare bees and birds in urban gardens

Tue, 2022-08-16 11:18
Little is known about what drives rare biodiversity in cities. Rare plant species in urban gardens may be the answer. The plants in turn attract rare bee and bird species, according to a Dartmouth College-led study looking at urban gardens in…

New model developed to predict landslides along wildfire burn scars

Tue, 2022-08-16 11:18
A wildfire followed by an intense rainstorm is often a recipe for disaster. Without vegetation to cushion rainfall, water runoff can turn into a fast-moving, highly destructive landslide, called a "debris flow," which often has the power to wipe out…

Integrative biological science and training are the focus of 4 new institutes

Mon, 2022-08-15 14:07
From understanding the multifaceted transmission of disease to deciphering how living organisms adapt to harsh conditions, answering big questions in biology requires interdisciplinary research and scientists engaging and partnering with those from…

Invasive species' success may lie in living fast, dying young

Mon, 2022-08-15 10:24
For some species conquering new territory, it might be better to live fast and die young. In a new study, biologists at the University of Iowa looked at why a type of freshwater snail that has invaded ecosystems worldwide has been so successful…

Oldest DNA from domesticated American horse lends credence to shipwreck theory

Mon, 2022-08-15 10:24
An abandoned Caribbean colony unearthed centuries after it had been forgotten and a case of mistaken identity in the archaeological record have conspired to rewrite the history of Assateague, a barrier island off the Virginia and Maryland coasts…

Engineers improve catalyst that destroys 'forever chemicals' with sunlight

Thu, 2022-08-11 10:33
Chemical engineers at Rice University have improved their design for a light-powered catalyst that rapidly breaks down PFOA, or perfluorooctanoic acid, one of the world's most problematic "forever chemical" pollutants. These pollutants aren't easily…

'Plaza' in ancient city of Cahokia near today’s St. Louis was likely inundated year-round

Thu, 2022-08-11 10:32
The ancient North American city of Cahokia had as its focal point a feature now known as Monks Mound, a giant earthwork surrounded on its north, south, east and west by large rectangular open areas. These flat zones, called plazas by archaeologists…
