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 / 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 / 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 ...
