Scooping the guts out of bacteria and refilling the exoskeletons with an expansive fluid reveals if whether a microbe is structurally strong or weak.

Understanding more about how a microorganism produces methane and carbon dioxide could help scientists cut greenhouse gases in the atmosphere.

Around 2 billion years ago, there was a mass die-off of microbes. Researchers say it rivals the loss of life from the dinosaurs' extinction.

Microbes from salty, subzero waters in the Arctic could give researchers a glimpse of the kinds of environments where they might one day find alien life.

A warmer tundra means more greenhouse gases from microbes, new research shows. That's bad news for fighting climate change.

"...it just shows how much is still out there in the ocean that we don't know."

New research shows "a new way that tiny microorganisms can have an outsized impact on a large-scale geological process and the Earth's climate."

Researchers are working on "sustainable, carbon-neutral, and low-cost" bioplastics.

There may have been many evolutionary paths in the development of organs that host useful bacteria.

Connections between gut bacteria may be just as important as which bacteria you have in your microbiome.
