In some deep subterranean aquifers, cells have a chemical trick for making oxygen that could sustain whole underground ecosystems.

Extreme microorganisms carpeting the Atacama Desert in Chile illuminate how life might have first taken hold on Earth’s surface.

New research reveals how marine microbes use an extra membrane that once had digestive functions to boost their yield from photosynthesis.

As researchers race to cultivate more of the intriguing cells from the deep seafloor, the few cells now growing in labs are giving us our best glimpses of the forerunners of all complex life.

“Virovores” — organisms that survive and multiply by eating viruses — might influence the flow of energy through ecosystems.

Tiny genetic sequences in a mother’s bacteria seem to hop into the infant’s bacteria, perhaps ensuring a healthy microbiome later in life.

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates.

New work suggests that the radiolytic splitting of water supports giant subsurface ecosystems of life on Earth — and could do it elsewhere, too.

The physicist Jeff Gore tests theories about microbe communities experimentally and finds new rules governing ecological stability.
