A new study analyzes three asteroid and two meteorite samples to see if space rocks smacking into Earth could’ve helped ...

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 ...

Methanogenic archaea are increasingly being recognized as functional players in the gut’s ecosystem, rather than merely producers of gas. A tightly controlled human feeding study suggests that ...

Scientists have solved a long-standing mystery about methanogens, unique microorganisms that transform electricity and carbon dioxide into methane. The results could pave the way for microbial ...

Diversity and taxonomy of methanogens / David R. Boone, William B. Whitman, and Pierre Rouvière -- Microscopy / G. Dennis Sprott and Terry J. Beveridge -- Physiological ecology of methanogens / ...

The process by which plants and algae acquire sulfur—converting sulfate into sulfide—requires a lot of energy and produces harmful intermediates and byproducts that need to be immediately transformed.

Meet methanogens — gut microbes that turn fiber into methane and extra energy. But not everyone has them. Nearly half of us are natural methane producers. That's because some people’s gut microbiomes ...

An electron microscope image of single-celled methanogens, members of the archaea branch of the tree of life. They are ubiquitous in oxygen-free environments, turning simple foods into methane, a ...

An estimated 1 billion tons of methane is produced each year by anaerobic microorganisms called methanogenic archaea. As methane is a potent greenhouse gas, increasing atmospheric concentrations of ...

The history of the Earth has been one of physical extremes—extreme atmospheric conditions, extreme chemical environments, and extreme temperatures. There was a time when the Earth was so hot all the ...
