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 ...

A novel method to manipulate the inner structure of cells connects several scientific fields and could represent a ...

For the first time, high-resolution time-lapse videos of tiny bits of living plants show how they assemble their protective cell walls, researchers report March 21 in Science Advances. The image ...

Brain cells are constantly swallowing material from the fluid that surrounds them—signaling molecules, nutrients, even pieces of their own surfaces—in a process known as endocytosis that is essential ...

Researchers have identified a new type of visual cell in deep-sea fish larvae that challenges a century of knowledge about ...

The beta cells of the pancreas are responsible for releasing the hormone insulin, which is vital for the absorption of glucose from the bloodstream. Various factors can impair the ability of these ...

It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...
