Researchers studied ancient iron-oxidizing bacteria to understand their role in Earth's early iron formations. The study found that nitrate-reducing bacteria produced toxic nitrogen monoxide, ...

Distributing iron particles produced by bacteria could "fertilize" microscopic ocean plants and ultimately lower atmospheric carbon levels, according to a new paper in Frontiers. "It is important that ...

MADISON, Wis. -- Research published this week by University of Wisconsin-Madison scientists shows how bacteria can degrade solid bedrock, jump-starting a long process of alteration that creates the ...

Scientists have long been fascinated by the organic-mineral filaments that extend from the surface of some iron-oxidizing bacteria living in environments from streams to hydrothermal vents. But ...
