A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and disease. Cedars-Sinai researchers have identified a biological repair process ...

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 ...

A quick revision guide covering key concepts, biomolecules, cell organelles, and essential NEET-style MCQs to boost exam preparation.

When we need to recharge, we might take a vacation or relax at the spa. But what if we could recharge at the cellular level, fighting against aging and disease with the microscopic building blocks ...

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 ...

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

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

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