Acclaimed neuroscientist Fred Gage is a serial trailblazer. Decades of dogma were overturned when his team confirmed the adult brain continues to make new brain cells. Incredibly, now scientists can even turn skin cells into brain cells with a chemical push! But, if their potential to treat brain diseases or damage is to be realised, transplanted cells need to be able to call your brain home. Stanford biologist James Weimann has a major advance.
