“Now, scientists led by Jinbo Huang, a molecular biologist at ETH Zürich, have invented a battery-powered interface that they call “the direct current (DC)-actuated regulation technology,” or DART, that can trigger specific gene responses with an electric current. Huang and his colleagues described the device as “a leap forward, representing the missing link that will enable wearables to control genes in the not-so-distant future,” according to a study published on Monday in Nature.”
