A recent study suggests that these microbes may also influence an important aspect of fitness – muscle strength. Muscle strength is a crucial feature of health for many reasons. It supports our joints ...

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 ...

Urban parks are a vital component of urban ecosystems and provide distinctive habitats for soil microorganisms. Yet ...

Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin ...

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

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 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, ...

A study on wild northern cardinals shows that stress can change gut microbes and affect bird health in measurable ways.

Jérôme Comte is a member of the Groupe de Recherche Interuniversitaire en Limnologie (GRIL), and has received funding from NSERC, Genome Canada, Génome Québec, FRQNT and OSMOZ. Christophe Langevin is ...

At the northern edge of Chile’s Atacama Desert sits a pile of rocks that’s so big that you can see it from space—and it’s teeming with invisible activity. Billions of microbes are hard at work ...
