A light switch that wakes sleeping cancer

Some cancer cells hide by going to sleep. In this dormant state they survive treatment and wake up later. Scientists at ETH Zurich built a tiny switch that reacts to light. The light flips the switch and destroys the receptors these sleeping cells depend on. That leaves the hidden cells open to attack again. The work is early and done in the lab, not yet in people. Still, it points to a way to reach the cancer cells that usually slip away.
