Cells are crowded with proteins and nucleic acids. A new study measures subcellular densities across organisms to uncover how ...

For the first time, researchers at Umeå University have observed the same type of programmed cell death in microalgae as in humans. The discovery, published in Nature Communications, shows that this ...

It's tiny and needy, but is it alive? That's a question prompted by recent research that highlights a surprisingly complex part of biology. The organism in question is a microbe called Sukunaarchaeum ...

A growing number of new studies have found that, at least for some cells, death isn’t the end, but the beginning of something ...

Chloroplasts, the parts of cells that allow plants and algae to photosynthesize, are thought to have originated more than 1 billion years ago, when photosynthetic cyanobacteria lived symbiotically ...
