Everything the brain does—from storing memories to interpreting sights to regulating emotions—requires energy, all produced ...

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus ...

Where do these mitochondria come from? It is very likely that injuries cause cell lysis, degradation, and tissue breakdown (necrosis), which release the contents of cells, including broken ...

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 ...

The researchers who made the discovery propose that the independent mitochondria may be released by cells for signaling purposes, although more work is needed to validate that hypothesis. “It’s very ...

Scientists at Sanford Burnham Prebys and collaborators across the country published findings March 5, 2025, in Nature Communications showing that the mitochondria powering our cells also control ...

For instance, the length of the leaf cell above is ten times the diameter of a red blood cell. If you increase a number by one order of magnitude, you are multiplying the number by 10. If you ...
