1. Robotic gripper runs on coffee … and balloons – The human hand is very complex and replicating it is very challenging. But now researchers have found out how to mechanically replicate it McGyver style with common household objects, ground coffee and a latex party balloon.
“This is one of the closest things we’ve ever done that could be on the market tomorrow,” Lipson said. He noted that the universality of the gripper makes future applications seemingly limitless, from the military using it to dismantle explosive devises or to move potentially dangerous objects, robotic arms in factories, on the feet of a robot that could walk on walls, or on prosthetic limbs.
Here’s how it works: An everyday party balloon filled with ground coffee — any variety will do — is attached to a robotic arm. The coffee-filled balloon presses down and deforms around the desired object, and then a vacuum sucks the air out of the balloon, solidifying its grip. When the vacuum is released, the balloon becomes soft again, and the gripper lets go.
2. New films lead to skeptical articles about psychics. Two current films in theaters now involve alleged psychics who claim to be able to talk to the dead, Clint Eastwood’s Hereafter and Woody Allen’s You Will Meet a Tall Dark Stranger. Now I’ve only seen the Woody Allen film because (A) Eastwood tends to make boring films and (B) I don’t find dialogue like “It’s not a gift; it’s a curse” particularly profound or, you know, original. Also, Allen’s film was fairly unapologetically skeptical while Eastwoods (and maybe I’m wrong) looks less so. But what I find interesting is that both films have led to interesting skeptical articles about psychic claims, one an interview with Woody Allen, where he reiterates his atheism, and the other, a review by Roger Ebert of Hereafter.
