It is possible that extremophile microbes lcould exist on icy moons and planets with conditions similar to subglacial waters or the ocean floor.

Around 1.7 billion years ago, eukaryotes—the building blocks of complex life—first appeared on Earth, and now scientists have ...

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, ...

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 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, ...

Scientists are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors could be the key.

Sift through your memories and excavate an image of a fossil. Maybe you’re picturing dinosaur bones, the imprint of an ammonite, or the fronds of a fern etched into stone. But there’s a whole other ...

When you hear the words “greenhouse gas,” your mind probably goes to carbon dioxide, the concentration of which has been steadily rising worldwide, leading to a feedback loop of absorbing and trapping ...

In some parts of the deep ocean, it can look like it's snowing. This "marine snow" is the dust and detritus that organisms slough off as they die and decompose. Marine snow can fall several kilometers ...

Gut dysbiosis caused by a high-fat diet can allow bacteria to move from the gut to the brain in mice, according to a new ...
