New model sheds light on day/night cycle in the global ocean

Tue, 2022-08-30 10:40
Phytoplankton are the foundation of all life on the planet. Understanding how these photosynthetic organisms react to their ocean environment is important to understanding the rest of the food web. But computer models of the global ocean…

Stars determine their own masses

Tue, 2022-08-30 10:38
Last year, a team of astrophysicists launched Star Formation in Gaseous Environments, or STARFORGE, a project that produces the most realistic, highest-resolution 3D simulations of star formation to date. Now, the scientists have used these…

Subsurface water on Mars defies expectations

Mon, 2022-08-29 10:55
A new analysis of seismic data from the InSight mission to Mars has revealed some surprises. The first: the top 300 meters of the subsurface beneath the InSight landing site near the Martian equator contains little to no ice. "We find that Mars'…

Even modest climate change may dramatically alter Earth's northernmost forests

Mon, 2022-08-29 10:52
Even relatively modest climate warming and associated precipitation shifts may dramatically alter Earth's northernmost forests. The woodlands constitute one of the planet's largest nearly intact forested ecosystems and are home to a big chunk of the…

Engineers build a self-aware, self-training robot that can avoid obstacles and assess damage

Thu, 2022-08-25 10:59
Engineers at Columbia University working on a project enabled by the National Artificial Intelligence Institute in Dynamic Systems and three separate grants from the U.S. National Science Foundation have built a robot that learns from itself instead…

Day or night — your brain is always listening

Thu, 2022-08-25 10:56
You're fast asleep. But your brain isn't taking the night off, according to new research funded by the U.S. National Science Foundation. Researchers studied activity in the human cerebral cortex in response to music and other sounds. They observed…

NSF announces new awards to understand coastal systems and tackle coastal hazards

Wed, 2022-08-24 12:00
U.S. coastlines are heavily populated areas with critical public resources, such as housing, transportation infrastructure, freshwater supplies, and electricity generation and distribution facilities. These coastlines are also increasingly vulnerable…

Researchers create an immersible glove with a secure grip

Wed, 2022-08-24 10:48
Researchers at Virginia Tech, working on a project made possible by a grant from the U.S. National Science Foundation, have developed a glove they designed based on the adhesive abilities of the octopus. The result is a glove that can be used…

First light observations of chemically rich star HD 222925 captured

Wed, 2022-08-24 10:47
The U.S. National Science Foundation's NOIRLab-operated Gemini South Telescope used its latest upgrade — GHOST, the Gemini High-resolution Optical SpecTrograph — to capture observations of HD 222925, a star more than 1,400 light years away. The star…

Researchers use artificial intelligence to create a 'treasure map' of undiscovered ant species

Tue, 2022-08-23 10:18
Although small, invertebrates have an outsized influence on their environments, pollinating plants, breaking down organic matter and speeding up nutrient cycling. And what they lack in stature, they make up for in diversity. With more than 1 million…

Understanding how rechargeable aqueous zinc batteries work

Tue, 2022-08-23 10:18
Researchers have hoped that rechargeable zinc-manganese dioxide batteries — which promise safety, low cost and environmental sustainability — could be developed into a viable option for grid storage applications. Engineers at the University of…

New NSF awards seek to broaden participation in biology through research experiences for recent college graduates

Mon, 2022-08-22 12:01
To reduce the barriers to entry into careers in the biological sciences and produce a more diverse workforce, the U.S. National Science Foundation has made 12 new awards totaling more than $35 million through its Research and Mentoring for…

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…
