This microbe can survive doses of radiation that would obliterate any other living thing. Here’s what this means for science ...

Scientists trace an ancient microbe, Asgard archaea, that gave rise to humans, animals, and plants more than 2 billion years ...

The vast community of microbes in the human gastrointestinal tract–the gut microbiome, has many close links to human health..

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple loop at the cell’s center. A giant microbe called Thiovulum imperiosus has now ...

Can life exist without the very metabolic machinery that defines it? The discovery of Candidatus Sukunaarchaeum mirabile ...

A new study reveals how gut bacteria may initiate ulcerative colitis by weakening immune defenses before inflammation occurs.

Evolutionary diagrams usually connect humans and monkeys with common primate ancestors, but now, scientists say there’s a missing link that deserves a spot on that family tree – our bacteria, fungi, ...

If something similar occurs in humans, and given growing evidence that the gut microbiome matters for health, genetic influence on human health may be underestimated in large studies; genes may affect ...

It may be small, its habitat harsh, but a newly discovered single-celled microbe leads the hottest existence known to science. Its discoverers have preliminarily named the roughly micron-wide speck ...

Cramped in a small submarine 2,500 meters below the Pacific’s surface in 2006, microbiologist Hiroyuki Imachi scanned the ocean floor for signs of microbial life. As the sub drifted over the bottom of ...
