Scientists supervise a robot as it performs a surgery in a photo published Wednesday in the journal Science Translational Medicine. A team of U.S. doctors have shown for the first time that soft tissue surgery can soon be performed entirely by a robot on humans, putting surgery one step closer into the realm of intelligent machines. The so-called Smart Tissue Autonomous Robot (STAR) succeeded in suturing and reconnecting bowel segments in living pigs and all the animals survived with no complications.Xinhua
