This week, we’re examining the scientific perspective on “psychic powers” like telepathy, telekinesis and remote viewing. We’ll speak to science author Brian Clegg about his new book Extra Sensory: The Science and Pseudoscience of Telepathy and Other Powers of the Mind. And we’ll speak to Ricardo Chavarriaga Lozano, researcher in non-invasive brain-computer interfaces, about experiments working on connecting different animals directly through their brains.
