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 / 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 / How early farming unintentionally bred highly competitive 'warrior' wheat

An evolutionary "arms race" for light and space led to the early domestication of wheat, according to new research that could offer fresh insights into crop design. The study led by Dr. Yixiang Shan and Professor Colin Osborne, ...

Phys.org / Quantum trembling: Why there are no truly flat molecules

Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a ...

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 / 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 / A few weeks of X's algorithm can make you more right-wing—and it doesn't wear off quickly

A new study published in Nature has found that X's algorithm—the hidden system or "recipe" that governs which posts appear in your feed and in which order—shifts users' political opinions in a more conservative direction.

Phys.org / How fast is the universe expanding? Supernova could provide the answer

That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A research team at the ...
