Gut microbe linked to depression in large health study | Science

by

The trillions of bacteria in and on our bodies can bolster our health and contribute to disease, but just which microbes are the key actors has been elusive. Now, a study involving thousands of people in Finland has identified a potential microbial culprit in some cases of depression. The finding, which emerged from a study … Read more

How Gut Microbe Symbiosis Helps Squirrels Keep Their Muscles During Hibernation

by

Ground squirrels spend the end of summer gorging on food, preparing for hibernation. They need to store a lot of energy as fat, which becomes their primary fuel source underground in their hibernation burrows all winter long.   While hibernating, ground squirrels enter a state called torpor. Their metabolism drops to as low as just … Read more

Soil Microbe Could Clean Up Nuclear Waste

by

Fission in nuclear reactors forges radioactive metal by-products so toxic that they must be stored deep underground, at great cost and effort, for millennia. But a protein made by a common microbe could help ease this hazardous burden, researchers report in the Journal of the American Chemical Society. Two of nuclear waste’s most problematic ingredients … Read more
