Beyond bacteria, fungi and archaea are emerging as powerful regulators of digestion, immunity, and disease risk, revealing ...

Featured oral presentation at Digestive Disease Week 2025 demonstrates significant modulatory effects of palatable elemental diet on methanogens in managing the gut microbiome beyond just bacteria ...

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 ...

Methanogens are organisms so tiny that most people never notice them, yet they are nearly everywhere — in lakes and wetlands, wastewater treatment systems and landfills, and even inside the human ...

Two-thirds of global methane release is likely due to natural emission during anaerobic (oxygen-free) activity of single-celled microorganisms called archaea. The protein mechanism has now been ...

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

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 ...

Just call them archaea (ar-kee-uh) - archaebacteria are no more. Archaea were once considered to be quite similar to bacteria, but these prokaryotes are just weird enough to be classified in their own ...

Microbiology has always been about recognizing the scale of what is unknown. In the beginning, the unknown was that microbes existed at all. The invention of the microscope proved that these tiny, ...

It's tough to be a microbe. Microbes often live in extreme environments and feed on waste materials-processing them in ways that are often useful-and they perform their tasks every day without any ...
