Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

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 ...

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our ...

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.

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, ...
