From the flamboyant blossoms and birds of rainforests to the living rainbows of coral reefs, Earth’s surface is teeming with ...

Indeed, archaea and bacteria appear very similar biologically (members of both groups consist of tiny cells without much internal structure) and different from eukaryotes. However, until ...

Most life on Earth relies on the sun's energy for survival, but what about organisms in the deep sea that live beyond the ...

Our results thus indicate that, despite the potentially suitable conditions, AOA and anammox bacteria do not necessarily occupy similar niches, at least not at our site in the Arabian Sea ...

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings ...

The origins of life on Earth have long fascinated scientists, particularly the nature of the last universal common ancestor ...

I am an environmental microbiologist who studies microbial communities in diverse ecosystems. Microbes (Bacteria and Archaea) are ubiquitous in the environment and play essential roles in the cycling ...

But there are none. Instead, there is a yawning gulf. On one side there are the tiny bacteria and archaea, collectively known as prokaryotes. On the other side there are the huge and unwieldy ...

An oxygen sensor protein protects the enzymatic machinery of biological nitrogen fixation from serious damage, and its use in ...

Only simple, single-celled organisms were present, like bacteria and archaea, and the entire planet was covered with them. Asteroid impact during that time was frequent, and one such impact was from a ...
