A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

Many biological processes are regulated by electricity-from nerve impulses to heartbeats to the movement of molecules in and ...

Microtubules are dynamic, tubular polymers composed of αβ-tubulin dimers that form an essential framework within eukaryotic cells. They orchestrate a wide range of cellular functions including ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as ...

Researchers have found a way to revive tired or damaged cells by giving them a fresh supply of mitochondria, the tiny ...

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Akhilesh Gaharwar, a biomedical engineer and one of the researchers on the project at Texs A&M, said they have found a way to ...

A team of researchers has generated one of the most detailed 3D maps of human chromosomes, cataloging over 140,000 DNA looping interactions.

A new study identifies molecular factors that promote small vessel disease—and an active drug that can restore impaired ...
