Wisconsin scientists find a way to make human collagen in the lab

...ould stand perpetual guard in the body and provide instant warning of invading viruses or bacteria. "We can have total control of what goes on these very thin extended fibers," says Raines. "We are able to build these molecules up one atom at a time and we can manipulate them in very precise ways." The new...

Oops! Researchers publish new findings on the brain's response to costly mistakes

...has looked inside the human brain and captured the instant when someone makes a costly mistake.

One component is used to control steering,...

Hopkins researchers discover how brain protein might control memory

...ke more Arc protein almost immediately. "Arc is an instant and reliable readout for active cells in the brain," says Worley. But although scientists knew that active cells were making copious amounts of Arc, no one knew exactly what Arc was doing in those cells until now. To figure out what Arc was doing...
