Phys.org / Phonon lasers unlock ultrabroadband acoustic frequency combs
Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency combs, which consist of equally ...
Phys.org / Birds change altitude to survive epic journeys across deserts and seas
Every year, billions of birds undertake extraordinary migrations, crossing vast deserts and open seas with no place to stop, feed, or rest. A new international study published in iScience by a consortium of researchers from ...
Phys.org / Americium, curium and californium—crystallizing the rarest elements
Actinides are a group of heavy, radioactive elements that include uranium, plutonium, americium, curium, berkelium and californium. Understanding how these elements bond with other atoms (known as coordination chemistry), ...
Phys.org / How root growth is stimulated by nitrate: Researchers decipher signaling chain
When 200 natural accessions of the model plant Arabidopsis thaliana grown in a nitrate-enriched medium were compared, one observation stood out: some accessions formed significantly longer lateral roots than others. Genetic ...
Phys.org / Blood marker from dementia research could help track aging across the animal world
A protein called neurofilament light chain (NfL)—studied in humans in the context of neurodegenerative diseases and aging—is also detectable in the blood of numerous animals, and NfL levels increase with age in mice, ...
Phys.org / Social media advertising suppresses voting in targeted communities, research shows
Messages intended to suppress votes can be precisely delivered to particularly vulnerable and consequential groups of people via social media and keep millions of them from casting ballots, according to a new study that is ...
Phys.org / Neutron scattering helps clarify magnetic behavior in altermagnetic material
Scientists at the U.S. Naval Research Laboratory (NRL) have identified the true source of a magnetic effect seen in the material ruthenium dioxide (RuO₂), helping resolve an active debate in the rapidly growing field of ...
Phys.org / Study identifies oaks, dry duff and debris as top power line failure risks
Wildfires and power outages caused by vegetation near powerlines have contributed to some of the state's most destructive fires.
Phys.org / Scientists home in on Acinetobacter baumannii's resistance evolution
Acinetobacter baumannii is a bacteria which can become a virulent killer in health-care settings among severely ill patients. The germ has rapidly developed drug resistance to even last-line carbapenem drugs. Now a group ...
Phys.org / A hidden step before meiosis could reshape efforts to treat infertility
In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a group of specialized cells, known as "germ cells," which will later form sperm and eggs, these inherited ...
Phys.org / Could a recently reported high-energy neutrino event be explained by an exploding primordial black hole?
The KM3NeT collaboration is a large research group involved in the operation of a neutrino telescope network in the deep Mediterranean Sea, with the aim of detecting high-energy neutrino events. These are rare and fleeting ...
Phys.org / Quantum entanglement pushes optical clocks to new precision
By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze ...
