Scientist at Massachusetts Institute of Technology (MIT), have grown their own muscle tissue. This major milestone didn’t stop their curiosity, so they decided to stimulate those muscle tissues with light. The result caused individual muscle tissues to contract. With a 20 millisecond laser, getting the job done, this opens a whole new world of possibilities, including bio-robots. Hopefully a couple of decades from now, I’ll have my own bio-robot to get my laundry done.
