Phys.org / How a superionic state enables long-term water storage in Earth's interior
The cycling of water within Earth's interior regulates plate tectonics, volcanism, ocean volume, and climate stability, making it central to the planet's long-term evolution and habitability and a key scientific question. ...
Phys.org / Framework sets new benchmarks for 3D atom maps in amorphous materials
Researchers at the California NanoSystems Institute at UCLA published a step-by-step framework for determining the three-dimensional positions and elemental identities of atoms in amorphous materials. These solids, such as ...
Phys.org / Corals sleep like us, but their symbionts never rest
Sleep is essential for much of the animal kingdom. During the night, neuron and tissue repair mechanisms are activated to aid recovery from daily activity. This is risky: organisms that sleep are more vulnerable to predators. ...
Phys.org / Cryoelectron tomography reveals paracrystalline architecture of proteasome storage granules
Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. ...
Phys.org / Cross-border pollution tracking reveals unequal distribution of risk and responsibility
Microscopic airborne particles known as PM2.5 contribute to 100,000 premature deaths in the United States each year. A new University of Notre Dame study finds that 40% of these deaths can be attributed to pollution that ...
Phys.org / Mineral dust accelerates Greenland ice sheet melt by promoting algae growth
Large-scale melting of the Greenland Ice Sheet is irreversible and happening at a rapid rate, and now a new international study is the first to understand why. A University of Waterloo scientist and a team of international ...
Phys.org / Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the ...
Phys.org / Laser beam flips a ferromagnet's polarity without heating the material
Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits ...
Phys.org / New radio method uncovers hidden bursts from dwarf stars and hints of exoplanets
An international team including Cornell researcher Jake Turner has developed a novel analysis method capable of uncovering previously undetectable stellar and exoplanetary signals hidden within archival radio-astronomical ...
Phys.org / Subtle rotations in ancient light: Decoding the universe's symmetry
A team of researchers studying the uncertainties associated with a phenomenon known as cosmic birefringence has developed a method to reduce uncertainties in its observational measurements, according to a new study published ...
Phys.org / Changing land use can increase threat of animal‑to‑human disease spread
Changes to land use can directly heighten the risk of diseases spreading from animals to humans, new University of Stirling–led research has shown. The study, led by Dr. Adam Fell of the University's Faculty of Natural ...
Phys.org / Record stretching of metallic bond reveals quantum conductance in gold atomic chains
Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have stretched a chain of gold atoms by a record-breaking 46%, providing direct evidence of how fundamental metal bonds behave under ...
