ENGINEERED PROTEIN THAT RESPONDS TO LIGHT COULD HELP RESTORE SIGHT

Summary from the TLDR newsletter

Science Corp., a Californian company, has created an engineered protein that could help blind people see. The protein, opsin, creates electrical currents when hit with light. Opsins usually need a powerful light source to generate a current, but Science's scientists were able to create opsins that generate an electrical current when exposed to regular indoor lighting. Science is currently building several things, including a device to restore vision and a chip that plugs into the brain using living neurons instead of wires - the new protein could help with both pursuits.
