Don't worry, yes, there are even more Musk machinations, but first let's broach something a little different -- and possibly lifesaving. A team of MIT engineers is developing a telerobotic system for neurosurgeons. It unveiled a robotic arm that doctors can control remotely using a modified joystick to treat stroke patients. The arm has a magnet attached to its wrist, and surgeons can adjust its orientation to guide a magnetic wire through the patient's arteries and vessels to remove blood clots in the brain. Like in-person procedures, surgeons will have to rely on live imaging to get to the blood clot, but the machine means they don't have to be physically with the patient.
