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 / 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 / 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 / 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 / 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 ...
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 / This nasal spray rewinds the aging brain, restoring memory and reversing inflammation in preclinical models
Picture this: your brain is a high-performance engine. Over decades, it doesn't just wear down, it also starts to run hot. Tiny "fires" of inflammation smolder deep within the brain's memory center, creating a persistent ...
Phys.org / Ethiopia's Afar Rift provides glimpse into life and death 100,000 years ago
The study of ancient cultures around Ethiopia during the Middle Stone Age (MSA) time period is important for understanding how some of the first Homo sapiens lived and eventually left Africa. Unfortunately, there are not ...
Phys.org / Bonobos' peaceful reputation cracks after a rival group attack leaves an infant dead
Bonobos are often described as gentle apes, generally calm primates that are seen as peacemakers in the animal kingdom. But this reputation may be coming under attack as a new study published in Scientific Reports reveals ...
Phys.org / Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover
When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at HZDR have now observed ...
Phys.org / Chandra explores interstellar medium of a bright low-mass X-ray binary
Using NASA's Chandra X-ray space telescope, astronomers have performed high-resolution X-ray spectroscopic observations of a bright low-mass X-ray binary known as GX 340+0. Results of the observational campaign, published ...
Phys.org / Droplet impacts reveal surprising physics in shear-thickening fluids
From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their flow properties change depending on how much force is applied, but the precise mechanics governing ...
