Four-legged robot simulates human motion
Four-legged, all-terrain robot can maintain its balance over rugged terrain while carrying a payload of up to 340 pounds; robot can also cope with man-made obstacles and gallop (well, something between “gallop” and “canter”) over impediments

Breakthrough: Dramatic increase in thermoelectric efficiency achieved
Two hundred years ago scientists discovered the thermoelectric effect: Certain materials can convert heat into electricity and vice versa; trouble is, most materials which conduct electricity also conduct heat, so their temperature equalizes quickly; until now: Boston College, MIT researchers solve this vexing problem

Ambient blue light resets tired workers' body clocks
Tedious work during the “wrong” hours of the body’s biological clock — think truckers who drive through the night, or security officers monitoring CCTV screens during the graveyard shift — often leads to drowsiness; falling asleep behind the wheel or in front of a security monitoring screen can lead to catastrophes; researchers develop a way to “fool” the brain to think it is morning
