Scientists Are Trying To Study Human Neurons… In Rat Brains?
Scientists have a tricky time studying neurons, partially because they are remarkably difficult to grow in a lab. They need other cells around them, and they don’t replicate or reproduce like other cells do. In a new study in Nature, researchers figured out that they can take a ball of human brain ... Show More

Black bears are moving into the neighborhood. How do we coexist?
Living with black bears is complicated. They’re huge, hungry, and they really don’t care about your hostas. After a long period of being overhunted, black bears are on the rebound. And as they begin returning to parts of their native ranges, they’re finding humans there, too.Repo ... Show More

Why Scientists Just Mapped Every Synapse In A Fly Brain
To really understand the human brain, scientists say you'd have to map its wiring. The only problem: there are more than 100 trillion different connections to find, trace and characterize. But a team of scientists has made a big stride toward this goal, a complete wiring diagram ... Show More
