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 ...
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 / 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 ...
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 / 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 / Two-color X-ray pulses capture the same nanoparticle at two moments in time
One big dream of ultrafast science has been to watch changes in nanoparticles or biomolecules on their natural timescale. Experimentally, this can be realized by taking two snapshots of the same object only femtoseconds apart. ...
Phys.org / Isle of Jura research casts new light on how rivers carve through landscapes
The waters of the remote Scottish island of Jura have long been famous for making whiskey. Now, the island's rivers have helped geologists learn more about how rivers erode rocks, providing new evidence that what streams ...
Phys.org / Tiny polymer particles keep water jets stable for longer
Tiny, soft polymer particles—known as microgels—can help to stabilize extremely thin liquid jets. How this works is the finding of a study led by researchers at TU Darmstadt, which has been published in Nature Communications. ...
Phys.org / Decades-old museum specimens reveal 10 extraordinary new worms
Scientists have discovered that one of the most unusual creatures in the animal kingdom is far more diverse and evolutionarily complex than previously known. An international team led by the University of Göttingen has reconstructed ...
Phys.org / Six unusual structures identified at Earth's core-mantle boundary with the help of deep learning
Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study ...
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. ...
