Scientists have discovered how the amino acid leucine boosts the body’s energy production by protecting key mitochondrial ...

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 ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

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 ...

CHICAGO (CBS) -- Lysosomes – membrane-bound structures within each cell of humans and all animals – are sometimes known as the cells' "garbage disposals" or "cellular janitors." The structures are ...

RNA in cells performs an astounding number of functions. Messenger RNA carries the sequences of active genes to cellular machinery that turns it into proteins. And transfer RNA molecules are an ...

A novel technology that utilizes light of different wavelengths to control cellular functions by inducing reversible assembly and disassembly of molecules has been developed. This breakthrough could ...

In the rapidly evolving field of drug discovery, single-cell analysis has become an invaluable tool for understanding cellular heterogeneity and molecular pathways. However, traditional single-cell ...

Disrupted function of 'cleaning cells' in the body may help to explain why some people with obesity develop type 2 diabetes, while others do not. A study describes this newly discovered mechanism.

Which cell is the coolest? Experts weigh in on their favorite cell types and what makes each one special in science and ...
