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 ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

Cells can also send out packages called exosomes, lipid vesicles that bubble off from the cell membrane. But for about 20 ...

A study of the fossilised fur of six mammals from the Jurassic and Cretaceous periods has found they were all greyish-brown in colour, which would have helped them hide from dinosaurs ...

Aortic dissection is a life-threatening condition with complex immunological underpinnings. This article explored the causal relationships among immune cells, inflammatory proteins, and aortic ...

The duplication and inheritance of both the endoplasmic reticulum (ER) and Golgi apparatus is coupled to cell-cycle progression. Although the exact mechanisms underlying ER and Golgi inheritance ...

Automatic cell analysis with the help of artificial intelligence Date: February 25, 2025 Source: University of Göttingen Summary: Identifying and delineating cell structures in microscopy images ...

In the last few years, metabolism has been shown to be controlled by cross-organelle communication. The relationship between the endoplasmic reticulum and mitochondria/lysosomes is the most studied; ...

How bulk cytoplasm generates forces to separate post-anaphase microtubule (MT) asters in Xenopus laevis and other large eggs remains unclear. Previous models proposed that dynein-based, inward ...

Regulation of stem cell fate is best understood at the level of gene and protein regulatory networks, though it is now clear that multiple cellular organelles also have critical impacts. A growing ...

Organelles are distributed to daughter cells, via inheritance pathways. However, it is unclear whether there are mechanisms beyond inheritance, which ensure that organelles are present in all cells.
