Have you ever sensed that someone might be watching you? You get a prickly feeling at the back of your neck and turn to see a stranger staring at you across the room. It sometimes seems that we can feel a person’s gaze as a physical sensation. Anthony and Jeff discuss research into this very sensation, in an attempt to figure out what we are actually sensing. Then, scientists have found that young American alligators can regrow their tails up to nine inches, or around 18 percent of their body length. Jeff and Anthony ask whether this might eventually give us all powers like The Lizard from Spider-Man.
