Researcher Chris Harrison has developed a system called "Skinput," which turns a person's hand and forearm into a keyboard and screen. Check out a video of the prototype in action.
Professional paranormal investigator and feature columnist for Skeptical Inquirer science magazine, Joe Nickell, provided his skeptic's take on the paranormal. Nickell has investigated many so-called ghost sightings and experiences, and often is able to explain the anomalies in scientific terms. "What I'm trying to do with my work with ghosts [or bigfoot]... is to actually go and actually investigate... and provide the simplest and best scientific explanation for it," he said.
