Yaks may hint at a way to treat brain diseases like MS

A shaggy yak stands on rocky ground in a mountain valley with snowcapped peaks rising in the background.

Animals that live at high altitudes, such as this yak in Pakistan, have a genetic mutation that may suggest new ways to treat brain diseases like multiple sclerosis.
