Researchers uncover the “body-snatching” tactics of fungi that flourish immediately after wildfires.

A newly identified group of viruses may help suppress eukaryotes’ immune response and promote tolerance of endosymbiotic bacteria.

Researchers suggest the viruses can help endosymbiotic bacteria get along with their hosts.

Contrary to some hypotheses, the organelles did not descend from any known lineage of Alphaproteobacteria, researchers find.

A new study reports which types of corals make the most of the sunlight they receive. 

Spotted salamander (Ambystoma maculatum) embryos are tinted green by the oxygen-producing algae (Oophila amblystomatis) that grow inside.
