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

When, and where, did bats first take to the sky?
A consortium of researchers from around the world has sequenced the genomes of 103 bat species, tracing the evolutionary origin of bats back in time. Using both genetic samples and fossil records, the researchers place the earliest bats as arising in Europe some 60 to 65 million ... Show More

Pinky and the (lab-grown) Brain
It’s not great to be a lab rat. And it turns out, lab rats might not be that great for science either. Could the future be little lab-grown brain clumps?
Guests: Rachel Nuwer, science journalist; Lisa Genzel, professor of neuroscience at Radboud University

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
