Studies show that Nitrosopumilus maritimus microbes are able to adapt to ocean warming and iron deficiency, while maintaining their crucial role in the nitrogen cycle. This adaptability may influence the biochemistry and resilience of marine ecosystems in the face of climate change.
A new study has revealed that ancient archaea—the closest relatives of eukaryotes—possessed the genetic machinery for oxygen respiration even before their symbiosis with bacteria. This discovery changes our understanding of how complex cells originated.
A study of microbial life deep within a meteorite crater in Sweden has revealed that archaea and bacteria can survive and produce methane without access to light or external hydrogen. These findings support the hypothesis that life could potentially exist beneath the surface of Mars.
