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 / 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 / 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 / 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 / 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 / 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 ...
Phys.org / Hiding in plain sight: Discovery of cryptic species could double the number of vertebrates
There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That's not because of any errors ...
Phys.org / New 'scimitar-crested' Spinosaurus species discovered in the central Sahara
A paper published in Science describes the discovery of Spinosaurus mirabilis, a new spinosaurid species found in Niger. A 20-person team led by Paul Sereno, Ph.D., Professor of Organismal Biology and Anatomy at the University ...
Phys.org / Triplet superconductivity—physicists may have found the missing link for quantum computers
Many physicists are searching for a triplet superconductor. Indeed, we could all do with one, although we may not know it yet—or understand why. Triplet superconductors could be the key to achieving the most energy-efficient ...
Phys.org / Helping beekeepers fight mites through more effective treatments
Researchers from the USDA's Agricultural Research Service (ARS) and the University of California, Davis, are helping beekeepers protect their colonies from destructive varroa mites. In a new study, the researchers investigate ...
