Phys.org / Study reveals hidden 'chemical currency' fueling the ocean's carbon cycle
A new study, led by Woods Hole Oceanographic Institution (WHOI) and Columbia University, identifies a diverse set of molecules released by marine phytoplankton that fuel microbial life and help drive Earth's carbon cycle. ...
Phys.org / Why heights and snakes still hit harder: Study tracks fear sweat in 119 people
Fear-eliciting images of modern and ancestral threats are equally likely to evoke physiological reactions, despite their distinct evolutionary origins, according to a study published in the open-access journal PLOS One by ...
Phys.org / California's lead-ammo bans are working, but expanding condor ranges undercut gains
Recent data showing an increase in lead exposure and deaths among critically endangered California condors seems to fly in the face of decades of conservation measures, including bans on lead bullets and public-education ...
Phys.org / Rapid melting of Antarctic sea ice is largely driven by ocean warming, research reveals
Sea ice around Antarctica expanded for several decades until a dramatic decline in 2015. The reasons behind this are revealed by research led by the University of Gothenburg, which is published in Nature Climate Change.
Phys.org / 3D model predicts mosquito flight paths from sight and CO₂ cues
A mosquito finds its target with the help of certain cues in its environment, such as a person's silhouette and the carbon dioxide they exhale. Now researchers at MIT and Georgia Tech have found that these visual and chemical ...
Phys.org / Beavers can convert stream corridors to persistent carbon sinks
Beavers could engineer riverbeds into promising carbon dioxide sinks, according to a new international study led by researchers at the University of Birmingham. The paper, published in Communications Earth & Environment, ...
Phys.org / Snail-derived compound could be a safer anticoagulant compared to heparin
For more than a century, heparin has been the go-to anticoagulant to prevent harmful blood clots in blood vessels or the heart from forming or getting larger. However, a major side effect is an increased risk of excessive ...
Phys.org / Satellite data reconstruct 2025 LA fires, showing rapid spread in first day
A severe drought, powerful Santa Ana winds and a not-fully-extinguished brushfire combined to create the most destructive wildfire in the history of Los Angeles in early 2025. The Palisades Fire, which fully ignited on Jan. ...
Phys.org / How AI deep learning is helping scientists protect California's coastal ecosystems
Researchers at UCLA's Institute of the Environment and Sustainability have developed the most high-resolution statewide maps of California's kelp forests to date, giving researchers, conservationists and community members ...
Phys.org / Durable dual-atom catalyst enables high-temperature CO₂ to CO conversion
The conversion of carbon dioxide (CO₂) into carbon monoxide (CO), an industrial feedstock, has attracted significant attention as a key step for producing synthetic fuels and chemical products. However, because CO₂ is ...
Phys.org / White-rot fungi show promise for reducing pharmaceutical residues in biosolids
Antidepressants and other psychoactive drugs are designed to affect the human brain. But after they enter the water system in excrement or unused drugs flushed down the drain, traces of these compounds can enter the environment ...
Phys.org / Abalone shells could help trace seafood origins
The rocks beneath our feet are leaving a hidden signature in the shells of marine snails along Australia's ancient coastline, according to new research led by Adelaide University scientists. A study published in Proceedings ...
