Hardy bacteria in a lab survived pressures comparable to an asteroid strike on the red planet, suggesting a hypothetical scenario in which our planet was seeded with life. By Robin George Andrews No ...

Scientists are learning how to program bacteria like tiny biological machines. By editing DNA and building genetic circuits, ...

Researchers from King's College London and the University of Surrey have developed a new technique to measure the content of ...

Antibiotic use has been linked to changes in the gut’s bacterial species that can last for four to eight years 1. The gut ...

Some extremophiles are beyond extreme, thriving in conditions that would wipe out most life-forms. Piezophiles are organisms that prefer high-pressure conditions and have adapted their metabolisms ...

When you hear the words “greenhouse gas,” your mind probably goes to carbon dioxide, the concentration of which has been steadily rising worldwide, leading to a feedback loop of absorbing and trapping ...

"Extremophile" bacteria could survive asteroid impacts that are strong enough to launch them into space, suggesting that life ...
