Metabolism, far from being just a housekeeping function, underlies all changes in cell size and function ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

Viruses typically aren’t considered ‘alive,’ as many core biological functions are outsourced to their potential hosts. But a newly discovered organism appears to straddle the line between virus and ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

Even after decades of peering into cells, biologists are still finding surprises. In a twist, researchers at the University of Virginia and the National Institutes of Health uncovered a new organelle, ...

It is well established that cellulose synthesis in higher plants requires three different but related cellulose synthase (CESA) isoforms. Here the authors provide convincing biochemical and cryo ...

White blood cells help your body fight inflammation and infections. A high or low white blood cell count may be associated with a number of short-term or long-term health conditions. White blood cells ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...

More than a billion years ago a hungry cell devoured a tiny blue-green alga. But instead of the former simply digesting the latter, the duo struck a remarkable evolutionary deal. Now scientists are ...

LONDON — Could genes from the dawn of life hold the key to a stem cell revolution? A groundbreaking experiment could make it reality. Researchers have successfully created a living mouse using genetic ...

Researchers have developed synthetic genes that function like the genes in living cells. The artificial genes can build intracellular structures through a cascading sequence that builds ...

Animal and plant cells have different energy-producing structures inside them. For animals, that’s mitochondria, which convert chemical energy from food into a form that our cells can use. Plants and ...
