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 / 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 / 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 / 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 / How a hidden receptor switch could open new paths for cancer and neurological treatments
A research team at Leipzig University has identified a mechanism in adhesion G protein-coupled receptors (adhesion GPCRs), a specific group of membrane receptors. This mechanism is essential for the activity of many of these ...
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 / 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, ...
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 / 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 / CO₂ emissions from cultivated peat soils may be lower than assumed
Organic soils cover less than 9% of Norway's land area, and about 65,000 hectares are currently used as agricultural land. Emissions from these areas are presently estimated at more than 2 million tons of CO₂ equivalents ...
Dialog / Not so dark with Alena Tensor: Math framework could explain dark matter without invisible particles
Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, ...
