Hidden fuel for ocean microbes: Urea emerges as key energy source for marine ammonia oxidizers

Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen cycling. Yet, despite their ubiquity, scientists have long puzzled over how these microbes can flourish ...

Extreme engineering: Unlocking design secrets of deep-sea microbes

The microbe Pyrodictium abyssi is an archaeon—a member of what's known as the third domain of life—and an extremophile. It lives in deep-sea thermal vents, at temperatures above the boiling point of water, without light or ...

From the volcanic crater to the lab: Extremophiles offer a lesson in survival

"Adapt or perish, now as ever, is nature's inexorable imperative," wrote H. G. Wells. This principle—that survival requires change—was mastered billions of years ago by single-celled organisms living in extreme heat. Over ...

Uncovering a new genetic code in archaea opens doors for bioengineering applications

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in which one or two additional ...
