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 ...

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

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 ...

Scientists at St. Jude Children's Research Hospital have characterized a hidden intermediate state at the center of Src ...

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

Gene regulation is the process by which cells control the expression of their genes, determining when, where, and to what extent each gene is expressed. It is a fundamental mechanism that allows cells ...

Researchers shifted the focus to the internal properties of the membrane itself, specifically its viscosity, highlighting its critical role in controlling deformation and dynamics during essential ...

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

In specialized chambers throughout leading medical centers worldwide, patients breathe pure oxygen at pressures significantly higher than normal atmospheric conditions. This treatment, known as ...

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