Microbiology

At sea, biologists discovered microbial partners that together produce nitrogen, a nutrient essential for life. The pair are in the process of merging into a single organism.

Many microbes and cells are in deep sleep, waiting for the right moment to activate. Biologists discovered a widespread protein that abruptly shuts down a cell’s activity — and turns it back on just as fast.

Microbiologists are searching for a universal theory of how bacteria form communities based not on their species but on the roles they play.

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.
