Ellis L. Reinherz is in the Department of Medicine, Harvard Medical School, Boston, Massachusetts 02115, USA, and at the Dana-Farber Cancer Institute, Boston, USA. Immune cells called T cells have ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

The cell nucleus is considered to be the control center of vital cellular processes, but its material properties continue to puzzle scientists. An international research team has now developed a new ...

More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the origin of life itself—this merger radically changed the ...

Pili are short, hair-like structures on the cell surface of prokaryotic cells. They can have a role in movement, but are more often involved in adherence to surfaces, which facilitates infection, and ...

Plant a seed and, if the conditions are right, the seed grows. The process seems simple enough at first glance and is something many of us may feel like we learned in elementary school.

The structure of the rat parietal cell was examined by electron microscopy. The intercellular and intracellular canalculi are lined by microvilli which are more numerous and larger than those of other ...

A new structure in human cells has been discovered. The structure is a new type of protein complex that the cell uses to attach to its surroundings and proves to play a key part in cell division. A ...

At the heart of our cells, a previously unknown structure has just been identified, shedding new light on essential biological mechanisms. This discovery could transform our understanding of certain ...

Kanazawa University, report in ACS Applied Nano Materials a new method to precisely measure nuclear elasticity—the stiffness ...

A previously unknown structure discovered in our cells could pave the way toward new treatments for various genetic disorders. The existence of the organelle—which has been dubbed the "hemifusome"—was ...
