The New Gel That Regrows Brains
A new healing gel helped mice regrow brain tissue after a stroke, and scientists suspect someone out there is producing a bunch of ozone-destroying CFCs in ...
==========
A lot of us grew up hearing that you can’t regrow brain cells -- usually after we bumped our head on something. Scientists still debate whether that’s actually true, but one thing’s for sure: brains aren’t nearly as good at replacing cells as other parts of the body. And when the brain gets damaged by something like a stroke, that damage stays instead of getting fixed. But a new study in the journal Nature Materials suggests a way of reversing that destruction. For the first time, by injecting a specially made gel into mice, scientists were able to successfully coax the mice’s brains into growing back cells and structures that were destroyed by a stroke. And with millions of people suffering from the long-term consequences of strokes, this could be a first step toward repairing ...
