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 zoom into the birth of cosmic rainstorms with new CERN study
Every second, particles zip through your body at nearly the speed of light. They rain down from a storm high in the sky, where cosmic rays, a powerful type of interstellar matter, constantly strike atoms in Earth's atmosphere. ...
Phys.org / Snail shells are surprising weather time capsules
Snails carry weather records on their backs that could be used to map prehistoric cyclones, a University of Queensland study has shown. The project led by School of the Environment researchers examined the rings on the shell ...
Phys.org / How the 2024 solar superstorm drained Earth's radiation belt
In May 2024, Earth experienced its most intense geomagnetic storm since the Halloween storms of 2003. This "superstorm" filled night skies in many parts of the world with colorful aurorae, and it disrupted some infrastructure, ...
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 / Unused natural gas behind NYC's $300 million waste of a potent greenhouse gas
Methane emissions from the New York City metropolitan area are largely driven by natural gas use, according to a new study published today in Atmospheric Chemistry and Physics by researchers at the Lamont-Doherty Earth Observatory, ...
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 / 40-year-old prediction of how plastics 'mix' confirmed for the first time
A "mixing" phenomenon between plastic layers that had been predicted only in theory for 40 years has now been experimentally confirmed.
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 / Series of reactions reveals how complex carbon chemistry can begin in frigid space
Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a chemical journey that could eventually deliver ...
Phys.org / Parakeets, male or female, love a good fight
In a study of monk parakeets, researchers at the University of Cincinnati and Duke University found that sex has little to no impact on who initiates fights, who is targeted or who rises in the dominance hierarchy.
