A new gene therapy turns glial cells — abundant support cells in the brain — into neurons, repairing damage that results from stroke and significantly improving motor function in mice.

A diabetes drug promotes brain repair — but it only works in females

Study finds that the diabetes drug metformin, known to promote brain repair, can also help restore cognitive function in adult mice but only in females and in a way that is dependent on the sex hormone estradiol.
