Tiny Robotic Hand Has Strong Grip

Robotic Hand

Scientists have developed a pair of robotic hands that are both strong and sensitive

The tweezers can guide themselves to pick up and move individual cells without damaging them, and have a grip that can be as slight as 20 nanoNewtons of force. In fact, so advanced are the little grippers, that they can be hitched up to a microscope and, with the right software, function without human control. More below.

Sweat Ducts May Act As Antenna For Lie Detection

 Sweat Ducts May Act As Antenna For Lie Detection

Politicians now have a new reason to worry – a technology that can determine if they are lying… from a distance.

Our skin may contain millions of tiny “antennas” in the form of microscopic sweat ducts, say researchers in Israel. In experiments, they found evidence that signals produced by bouncing electromagnetic waves off the tiny tubes might reveal a person’s physical and emotional state from a distance.
