[T]he Pet-Proto, a predecessor to DARPA’s Atlas robot, is confronted with obstacles similar to those robots might face in the DARPA Robotics Challenge (DRC). To maneuver over and around the obstacles, the robot exercises capabilities including autonomous decision-making, dismounted mobility and dexterity. The DARPA Robotics Challenge will test these and other capabilities in a series of tasks that will simulate conditions in a dangerous, degraded, human-engineered environment.

A look at the cavity quantum electrodynamics work that Serge Haroche pioneered. Dave Winelend, the other physics Nobel winner, does investigations using ion traps.

There’s a number of short videos with Wineland done by the Institute for Quantum Computing — From Atomic Clocks to Ion Traps: David Wineland at IQC

Harvesting an Ant Farm

Have you ever dreamed of shrinking yourself so you could go inside an ant colony and see exactly what they do in there? You may have owned an ant farm when you were a kid, but do ants really behave how they would normally within a clear plastic sheath only about 1 inch by 1 inch? Doubtfully. Playing with ants isn’t just for kids as Florida State University professor Walter Tschinkel shows us in just a moment. Tschinkel replicates the form of ant colonies by pouring molten aluminum into the tunnels, letting the metal harden, and then meticulously excavating the result.
