Thanks to a group of Harvard University scientists, we've gotten one step closer to making Jedi mind trick a reality. In their most recent experiment, the scientists were able to remotely flick a rat's tail with the power of human thought by using a brain-to-brain computer interface (BBI). With the successful outcome of this test, the researchers say they hope to experiment with more complex signals, such as feelings of hunger or sexual arousal, and eventually invite another human in place of the rodent.
