One DNA letter can trigger complete sex reversal

Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development in mice. In the new study, published in Nature Communications, a single-letter insertion in a non-coding ...

Mathematical model predicts fish freshness in real time

Every day, fish caught in oceans and seas around the world pass through a long journey before reaching supermarkets, restaurants, and home kitchens. Along the way, their freshness steadily declines, often in ways that are ...

Glucose transport may hinge on a fleeting transition-like state

Stockholm University and SciLifeLab researchers have uncovered how glucose transporters move nutrients into cells, bridging a long-standing gap between structure and function in membrane biology. "Our study shows that these ...

AI uncovers hidden immune defenses inside bacteria

Researchers at the Massachusetts Institute of Technology (MIT) have discovered thousands of new proteins that protect bacteria from virus attacks using an AI system called DefensePredictor. What would usually take months ...

Split shift: A surprising twist in the biology of aging

A new Yale study of flatworms, a species with the unique ability to regenerate, reveals that disruptions in the body's internal map of cellular organization may play a part in age-related decline.

Researchers clarify how cells remove damaged endoplasmic reticulum

The cell's endoplasmic reticulum (ER) plays a central role in protein synthesis, folding, and calcium (Ca²⁺) storage. When damaged, ER-phagy (self-eating) removes affected ER regions via double-membrane vesicles called autophagosomes. ...

Pigeons tend to respond 'at the edge of chaos,' study finds

If you were rewarded for following a particular pattern of behavior, wouldn't you keep doing it? The answer turns out to be more nuanced than you might think. In a new study, University of Iowa researchers report that pigeons ...
