Phys.org / Quantum spin effects may enhance one-way electrical transport in chiral magnets
Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, researchers from Science Tokyo report. In chiral magnetic systems, electric current flows differently depending on its direction, ...
Phys.org / Ancient stardust grains were seeds for the earliest solids in the solar system
How did the first solids that made up planets, moons and asteroids form from the "hot soup" that characterized our solar system's earliest years? New research from Caltech analyzing pieces of a meteorite has found that, just ...
Phys.org / Ancient smallpox genomes reveal how European colonization brought the disease to the Americas
Researchers from Trinity College Dublin have recovered and analyzed the first ancient smallpox virus genomes ever identified in the Americas, providing the strongest direct evidence to date that the disease was introduced ...
Phys.org / Neptune's inner moons may be shattered remains of ancient icy worlds
In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Because of their small sizes and locations, these satellites have been difficult ...
Phys.org / Ancient Chinese seeds spanning 5,000 years train AI to ease archaeology's specialist bottleneck
Ancient plant seeds provide important archaeological evidence for studying the evolution of human civilization. Lingnan University and Shandong University have jointly developed the world's first artificial intelligence (AI) ...
Phys.org / Pacific Ocean pattern helps explain diverging wildfire trends in US and Australia
Two of the world's most fire-prone regions have followed strikingly different wildfire trajectories despite both experiencing a warming climate. Burned forest area has surged across the U.S. Southwest, while eastern Australia ...
Phys.org / Ancient turtle hunting could inform modern conservation throughout southern Caribbean
Despite the promise of rebounding green sea turtle numbers, many sea turtle populations continue to flounder under the pressures of changing climates, overfishing and urbanization.
Phys.org / Female birds have shorter lifespans than male birds across 35 North American species, researchers find
Birds have a lot to do in their short lives: defend territories, build nests, raise chicks and feed themselves. But the toll of these activities may be greater for female birds than for male birds. A new study by UCLA ornithologists ...
Phys.org / Chicken kidney sponge could be 'outstanding' at cleaning up polluted ports
Ports rank among the most disturbed marine environments. Pollutants like trash, oil and toxins from antifouling paints tend to accumulate in enclosed harbors. Invasive species arriving in ballast water may displace native ...
Phys.org / Scientists solve mystery of how muscle cells grow and stay healthy
In a study published in Nature Communications biophysicists unravel the mystery of how muscles form at the molecular level and maintain their function. The findings may help design treatments for muscle diseases such as dilated ...
Phys.org / Spectroscopy system detects aerosols using light reflected from traffic signs and tree trunks
Researchers have developed and tested an infrared spectroscopy system that can rapidly detect chemical aerosols from a distance by using light reflected from common surfaces such as traffic signs, tree trunks or painted surfaces. ...
Phys.org / From single projection to many possibilities: A new tool for climate risk assessment
Assessing how climate change will affect different regions usually requires running a complex chain of models. While this approach provides valuable insights, it is expensive and can cover only a limited set of scenarios ...
