How clean is the International Space Station?

State-of-the-art molecular analysis of dust samples from the International Space Station (ISS) has been employed to reveal new information about some of the potential bacterial agents present in the astronauts' space environment. ...

Researchers find hydrogen-supported life beneath glaciers

Using years of data collected from ice-covered habitats all over the world, a Montana State University team has discovered new insights into the processes that support microbial life underneath ice sheets and glaciers, and ...

Our microbes are starving, and that's a good thing

Each of us is only half human. The other half is microbial. Trillions of viruses, fungi, bacteria and other microscopic organisms coat our skin and line our vital organs.

Machine learning begins to understand human gut

The communities formed by human gut microbes can now be predicted more accurately with a new computer model developed in a collaboration between biologists and engineers, led by the University of Michigan and the University ...

Do gut microbes shape our evolution?

Scientists increasingly realize the importance of gut and other microbes to our health and well-being, but one UC Berkeley biologist is asking whether these microbes—our microbiota—might also have played a role in shaping ...

The evolutionary link between diet and stomach acidity

An analysis of data on stomach acidity and diet in birds and mammals suggests that high levels of stomach acidity developed not to help animals break down food, but to defend animals against food poisoning. The work raises ...
