We humans need oxygen to breath - for a lot of microbes it is a lethal poison. That is why microorganisms have developed ways to render oxygen molecules harmless. Microbiologists have now succeeded in ...

Sulfur is a fundamental element of life and all organisms need it to synthesize cellular materials. Autotrophs, such as plants and algae, acquire sulfur by converting sulfate into sulfide, which can ...

New research suggests that methanogens -- among the simplest and oldest organisms on Earth -- could survive on Mars. Methanogens, microorganisms in the domain Archaea, use hydrogen as their energy ...

Researchers test the viability of methane-producing microorganisms on different types of soils similar to those found on Mars. FAYETTEVILLE, Ark. — University of Arkansas researchers have tested the ...

Most natural methane emissions originate with microorganisms called methanogens, the metabolic rates of which, during growth in culture with unlimited substrate, change with temperature according to ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. Scientists have revealed two never-before-seen groups of microbes that live in the hot springs of Yellowstone National ...

The Methane Problem in Rice Farming Rice paddies, which provide a staple food for billions, are a substantial source of atmospheric methane, a greenhouse gas over 80 times more potent than carbon ...

The biodiversity of the Earth never ceases to astonish. One example that has radically changed the face of biology is the discovery of a group of organisms called archaea (pronounced “ar-kee-ah”). It ...
