Phys.org / Magma repeatedly breaks and heals during eruptions, microscopic evidence suggests

Explosive volcanic eruptions can be as destructive as they are difficult to predict, launching pyroclasts—the fragments of magma and rock blasted from a volcano—into the air and surrounding areas. These particles can have ...

Phys.org / Hidden receptor interactions may explain past failures of brain disorder drugs

Metabotropic glutamate receptors, which are important but difficult drug targets, interact in surprisingly varied ways with their principal regulatory proteins, according to two new studies led by Weill Cornell Medicine investigators. ...

Phys.org / Scientists discover dispersal mechanism and new gene family in harmful E. coli strains

Researchers from Tokyo Metropolitan University have identified how certain dangerous bacteria spread. They studied chain-like adherence pattern (CLAP) varieties of Shiga toxin-producing E. coli (STEC), finding that single ...

Phys.org / AI models enable cross-species mapping of cell biology

Researchers at Stanford Medicine have developed two new artificial intelligence models of the biological cell. The first, called universal cell embedding, paved the way for a second-generation model called TranscriptFormer, ...

Phys.org / Speedy electrons for brilliant laser light: Research paves the way for compact, inexpensive free-electron lasers

Extremely short, intense light flashes are in high demand to investigate atoms, molecules and new materials. Free-electron lasers (FELs) produce these flashes. But around the world, beam time available at large-scale user ...

Phys.org / How prehistoric coastal flooding shaped the Northern Adriatic

Researchers have shown how dramatic sea-level rise over a 5,000-year period profoundly changed the coasts of northern Italy, Slovenia and northern Croatia. Successive shaping and reshaping of coastal features influenced the ...

Phys.org / Structural study explains how cells stabilize protective membrane pockets

Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can result. Their structure ...

Phys.org / Active black holes reveal star-forming rings and shock waves in nine nearby galaxies

A new study of nine nearby galaxies has shown that actively growing supermassive black holes may contribute to, rather than prevent, star formation in their host galaxies.

Phys.org / Physicists help uncover 'spooky' quantum effect in the Large Hadron Collider

Physicists at the University of Oxford have helped confirm that one of the strangest phenomena in physics—quantum entanglement—occurs even among some of the heaviest and most fleeting particles ever created. The discovery, ...

Phys.org / Antibody cocktails could steer viruses into evolutionary dead ends

When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS-CoV-2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study from Harvard's ...

Phys.org / Radiation-tolerant rotifers rebuild broken chromosomes over successive generations

DNA repair mechanisms are essential for maintaining the integrity of our genome. When they malfunction, they can cause disease or contribute to the development of cancer. Nature, however, offers remarkable examples of organisms ...

Phys.org / Three DNA loops prove essential for efficient wing tissue regeneration in fruit flies

After an injury, DNA not only changes its activity but also the way it is organized spatially within the cell nucleus. In this process, certain regions of DNA establish new physical contacts through chromatin loops that act ...
