Plastic is made from oil and natural gas, which started out as fossilized plant and animal material. But buried deep underground for millions of years, those materials changed in important ways.

Should there be a recommended daily intake of friendly microbes we eat? For the first time, scientists have measured their amount in our food.

"This bacterial enzyme is the most efficient carbon fixer that we know of, and we came up with a neat explanation of what it can do."

Ground is collapsing and massive lakes are draining in a matter of days. Thawing permafrost is having profound effects on the region and its infrastructure.

Microbes that safely break down antibiotics could prevent opportunistic infections and reduce the spread of antibiotic resistance.

Scientists propose a new mechanism by which oxygen may have first built up in the atmosphere

Your kitchen sponge is a better incubator for diverse bacterial communities than a laboratory Petri dish, researchers report.

Months not eating or moving don’t result in muscle wasting and loss of function for animals that hibernate. New research found gut microbes help their hosts hold onto and use nitrogen to build proteins.

New findings may help researchers hone predictions for where phytoplankton will migrate with climate change.
