Researchers engineer light-activated skeletal muscle - MIT News Office: The group has genetically engineered muscle cells to flex in response to light, and is using the light-sensitive tissue to build highly articulated robots...
The researchers cultured such cells, or myoblasts, genetically modifying them to express a light-activated protein. The group fused myoblasts into long muscle fibers, then shone 20-millisecond pulses of blue light into the dish. They found that the genetically altered fibers responded in spatially specific ways: Small beams of light shone on just one fiber caused only that fiber to contract, while larger beams covering multiple fibers stimulated all those fibers to contract...
