Millions of unknown microbial genes discovered in Antarctica’s ocean reveal a hidden ecosystem that may influence carbon cycling and climate.

We become forgetful as we age. This is often seen as a universal truth, but in fact it is far from universal: some people remain incredibly sharp at 100 years old, while others experience memory loss ...

As mice age, changes in the microorganisms in their guts contribute to cognitive decline by altering signalling between the gut and brain.

As deep-sea waters warm, scientists expected trouble for the microbes that help keep ocean chemistry in balance. Instead, researchers found that Nitrosopumilus maritimus can adapt to warmer, ...

Roughly two-thirds of all emissions of atmospheric methane—a highly potent greenhouse gas that is warming planet Earth—come from microbes that live in oxygen-free environments like wetlands, rice ...

Investigating microplastics in agriculture reveals their effects on soil microbes and viruses, crucial for developing strategies for ecosystem restoration.

The experiment began with a straightforward prediction: microbes from older mice would age young ovaries. But when the results came in, the data pointed the other way. In a new study in Nature Aging, ...

Conservation biologists propose a daunting task: protecting Earth’s diversity of bacteria and other microbes. By Carl Zimmer Hundreds of scientists have joined together to save a group of species from ...

New studies show that a bacterial molecule, peptidoglycan, is present in the brain and fluctuates with sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting it ...
