Phys.org / Reversible electric control unlocks persistent chiral phonon states
Atoms in a material are rarely still. They jiggle back and forth in collective lattice vibrations known as phonons. Their motion can also carry a rotational element: In 2023, scientists at PSI experimentally proved the existence ...
Medical Xpress / MLC1 antibody identified as possible trigger of rare neurological autoimmune disorder
Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease of the central nervous system in which the immune system attacks structures in the brain, spinal cord and optic nerve. It mostly affects astrocytes, ...
Medical Xpress / Atherosclerosis may meet key criteria for autoimmune disease, evidence suggests
In autoimmune diseases, the immune system turns against the body through pathogenic high-affinity B cells or T cells, leading to severe organ damage. Multiple sclerosis (nervous system paralysis), type 1 diabetes (a strong ...
Phys.org / 'Quiet' pulsar suddenly reveals three glitches in 15 years of observations
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. ...
Phys.org / Extreme pressure turns blue pigment into record-long single-atom copper chains
As the electronics in our technology keep shrinking, traditional silicon-based chips are approaching their fundamental physical limits. Yet the wires connecting them might be able to shrink beyond conventional dimensions, ...
Phys.org / Neutrophil vesicles help Candida albicans evade immune-cell engulfment
The immune system is a highly sophisticated defense network designed to protect against pathogens. A research team from the Universities of Würzburg and Jena and the Leibniz Institute for Natural Product Research and Infection ...
Phys.org / New model measures economic risks solar storms pose to US power grid
In 1967, a solar storm nearly triggered World War III by jamming early-warning radar systems in the United States, causing U.S. leaders to think the Soviet Union was responsible. Though society averted catastrophe thanks ...
Phys.org / Ancient charcoal reveals evidence of wildfires near the South Pole
A journey back in time to the Late Cretaceous: A swampy rainforest with conifers and tree ferns stretches as far as the eye can see, dinosaurs roam through the misty wetlands, and the climate is mild and warm. The average ...
Phys.org / Dark plasma regions reveal overlooked source of reactive atomic oxygen
Scientists from Tokyo Metropolitan University have found a way to make plasma more effective for its wide-ranging uses, from antimicrobial applications to surface conditioning in the semiconductor industry. They mapped the ...
Phys.org / Reconstructed ancient protein maps how bacterial enzymes evolved distinct functions
How do related proteins develop different functions? This is the question investigated by a research team involving Kiel University, DESY and the Center for Structural Systems Biology (CSSB). Led by Holger Sondermann, professor ...
Medical Xpress / Scientists in China discover new tick-borne virus that causes flu-like illness
Scientists in China have identified a novel tick-borne virus that causes an influenza-like illness characterized by fever, fatigue, gastrointestinal (GI) symptoms and abnormal lab findings. The team, led by researchers from ...
Medical Xpress / Why scientists are looking to provoke disagreement among AI brain models
When people wanted to create better artificial intelligence, they looked to the brain for inspiration. Now the tables are turning, and researchers are using AI models to better understand the brain. But how do we judge which ...
