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 / New light-emitting nanoparticles can detect subtle chemical differences
A team of researchers from University of Toronto Engineering has created a new type of dye-sensitized nanoparticle that can detect target chemicals at very low concentrations while also distinguishing between molecules with ...
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 / Room-temperature skyrmion-based synapses could pave the way for energy-efficient AI
Artificial intelligence is transforming how information is generated, processed and stored, but its rapid expansion is also driving unprecedented demand for computing power and electricity. Developing hardware that can process ...
Phys.org / Getting photons into shape for reliable quantum communication
The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two atoms, for example) exchange ...
Phys.org / Lebanon: 400,000 years of climate and landscape history rediscovered
An international research team led by Dr. Gabriele Russo of the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen has re-examined historical fossil collections from Lebanon using modern ...
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 / 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 / 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 / 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 / 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.
