Medical Xpress / Stunning new maps of myelin-making mouse brain cells advance understanding of nervous system disorders
Johns Hopkins scientists say they have used 3D imaging, special microscopes and artificial intelligence (AI) programs to construct new maps of mouse brains showing a precise location of more than 10 million cells called oligodendrocytes. ...
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 / 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 / Scientists reveal best- and worst-case scenarios for a warming Antarctica
The climate crisis is warming Antarctica fast, with potentially disastrous consequences. Now scientists have modeled the best- and worst-case scenarios for climate change in Antarctica, demonstrating just how high the stakes ...
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 / The Princess of Bagicz: Dendrochronology settles debate over age of rare Roman-era wooden coffin
Dr. Marta Chmiel-Chrzanowska and her colleagues conducted a multidisciplinary analysis of the only known preserved wooden coffin from the Roman Iron Age, the Princess of Bagicz. The study, published in Archaeometry, used ...
Phys.org / NASA targets March for first moon mission by Artemis astronauts after fueling test success
NASA aims to send astronauts to the moon in March after acing the latest rocket fueling test.
Phys.org / Call me invasive: New evidence confirms the status of the giant Asian mantis in Europe
In the realm of entomology, few creatures command as much fascination as the mantis. Throughout history, these striking insects have been deeply woven into local myths and legends, sometimes respected as mystical soothsayers ...
Medical Xpress / Toxic exposure creates disease risk over 20 generations, epigenetic inheritance study suggests
A single exposure to a toxic fungicide during pregnancy can increase the risk of disease for 20 subsequent generations—with inherited health problems worsening many generations after exposure. Those are the findings of ...
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 / Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein ...
