Phys.org / Black hole feeding frenzy ends in lingering cosmic indigestion
Black holes are often portrayed as cosmic gluttons that swallow everything that comes too close. But new observations of a dramatic black hole outburst—led by Warwick Postdoctoral Fellow Dr. Noel Castro Segura—suggest the ...
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 / 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 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 / 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 / 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 / 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 / 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 / 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.
Dialog / Bacteria may identify a virus without recognizing its DNA
When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it can do any harm. Biology ...
Phys.org / Tiny fossils crack a Cretaceous cold case: Ocean acidification triggered one of the ocean's most severe extinctions
A 113-million-year-old marine murder mystery may finally be solved. Using chemical clues locked inside microscopic fossils, Northwestern University scientists found evidence that ocean acidification drove one of the largest ...
