Controlling genes with light

Duke University researchers have devised a method to activate genes in any specific location or pattern in a lab dish with the flip of a light switch by crossing a bacterium's viral defense system with a flower's response to sunlight. With the ability to use light to activate genes in specific locations, researchers can better study genes' functions, create complex systems for growing tissue, and perhaps eventually realize science-fiction-like healing technologies.
