<< The cells [live cells that can release insulin] were then embedded with tiny LED lights inside a hydrogel and transplanted under the skin of diabetic mice. And—get this—the entire system was controlled with a custom Android app, which remotely turns on the implanted LEDs and activates insulin-producing cells based on the level of circulating blood sugar levels. >>
