Phys.org / Ancient seabird guano reveals how climate change may shape future populations
By analyzing peat cores, researchers have shown how populations of nesting seabirds have fluctuated on a sub-Antarctic island over 8,000 years. They found that bird numbers rose and fell alongside shifts in climate, offering ...
Phys.org / Emerging in Alaska, dominant H5N1 strain spread continent-wide through migratory birds
An international group of scientists mapped the spread of the current dominant strain of highly pathogenic avian influenza virus through North American bird populations in 2024. Led by scientists from St. Jude Children's ...
Phys.org / As polar ice changes, so do the rules governing it
Sea ice is not just solid frozen water. It's riddled with tiny pockets and channels of liquid brine. Whether those pockets connect to form pathways determines whether seawater, nutrients and gases can move through the ice, ...
Phys.org / Machine learning tool pinpoints optimal locations for tree planting, offering a powerful tool for climate mitigation
Afforestation—establishing forests on previously non-forested land, or where forests have not existed for a long time—is one of the nature-based and cost-effective solutions for climate change mitigation because it offsets ...
Phys.org / Can naked mole rats peacefully hand over power?
Naked mole rats keep kingdoms underground. One queen bears all the children, while others maintain complex subterranean tunnels, forage for food, take care of newborns, and perform other necessary upkeep. This society hinges ...
Phys.org / Ocean eddies are amplifying climate extremes in coastal seas, study finds
New research reveals a powerful yet overlooked driver of climate change: intensifying ocean eddies. These swirling currents—that break off from major currents—are redistributing heat and nutrients in the ocean and amplifying ...
Phys.org / Marine sponge bacterium enzyme reveals a two-part route to make terpenoids
The molecular structure of an enzyme from a marine bacterium with potential industrial uses has been determined by RIKEN researchers. The insights they have gained could help make a range of useful compounds through genetic ...
Phys.org / Color test 'sniffs out' dangerous staph strains fast
Researchers have developed a rapid color-changing test that can distinguish between different strains of golden staph, including those likely to be virulent and antibiotic resistant. Golden staph is a major human pathogen ...
Phys.org / Rapid melatonin test can help astronauts and others easily monitor their biological rhythm
A simple test developed at Washington State University could eventually allow astronauts and others in round-the-clock occupations to monitor their biological rhythms in just minutes using a drop of blood, a paper test strip, ...
Phys.org / Hawai'i's songbirds are raiding neighbors' nests, and the losses could deepen a growing survival crisis
High in the forests of Hawai'i, songbirds are stealing twigs and moss from one another's nests. UC Riverside researchers found this quiet canopy crime is surprisingly common and could threaten species already struggling to ...
Phys.org / Referee decisions in soccer frequently overturned following VAR-assisted review: No external influences found
In an analysis of a video-assisted, pitch-side review of soccer (UK football) referee calls in the English Premier League, referees overturned their original call 95% of the time. However, these decisions had no statistical ...
Phys.org / Self-propulsion or slow diffusion: How bacteria, cells, and colloids respond to stimuli
What physical processes govern the movement of microscopic structures capable of interacting with their environment? The answer lies in two mechanisms: self-propulsion, to escape unfavorable locations; and slow diffusion, ...
