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 ...

(CN) — In a breakthrough discovery driven by international collaboration, scientists have finally clarified how cells manage one of their most essential functions: energy processing. The research ...

Let’s start with a quick biology refresher: Mitochondria are the powerhouse of the cell. They convert the food we eat into ...

Mitochondria are the powerhouses in our cells, producing the energy for all vital processes. Using cryo-electron tomography, researchers have now gained insight into the architecture of mitochondria ...

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

New research finds that sleep is essential for protecting brain mitochondria by transferring toxic metabolic waste from neurons to glial cells for disposal.

Biologists have long treated the cell as a chemical factory, but a new wave of research is forcing a rethink of that familiar picture. Instead of just tiny bags of reacting molecules, our cells appear ...

When HHMI Investigator Amita Sehgal started studying sleep 25 years ago, the topic elicited a yawn from most biologists. "In the year 2000, if I had suggested to my department that we hire people ...

The flux of protons from respiratory supercomplexes (blue) to ATP producing complexes (pink) powers the regeneration of ATP in mitochondria. Mitochondria are the powerhouses in our cells, producing ...
