Scent of a Terrorist

The military wants to turn odour recognition into a science to help fight terror. The Unique Signature Detection Project, is designed to help identify terrorists based on scents they secrete in their sweat, tears, urine and other bodily fluids — via digg

Plan For Cloaking Device Unveiled

A plan for a cloaking device has been unveiled. The design is pioneered by Professor Sir John Pendry’s team of scientists from the US and Britain. Proof of the ability of his invention could be ready in just 18 months time using radar testing. The method revolves around certain materials making light flow around the given object like water

Hydrogen Fuel Balls

The Department of Energy has filed a patent for hydrogen fuel balls. The proposed glass microspheres would each be a few millionths of a metre (microns) wide with a hollow centre containing specks of palladium. The walls of each sphere would also have pores just a few ten-billionths of a metre in diameter. They are supposedly safe and small enough to be pumped into a fuel tank in the same manner as petrol

Robo-Gecko Climbs Glass

Researchers at Stanford have developed a robot that mimics the extraordinary climbing skills of the Gecko. These creatures can climb sheer surfaces thanks to the intermolecular forces exerted by millions of tiny hairs their feet, called setae. The robot, Stickybot, has polymer pads on its feed with synthetic setae

Vatican Astronomer Denounces Creationism as Paganism

Believing that god created the universe in six days is a form of superstitious paganism, the Vatican astronomer Guy Consolmagno claimed. He has also said that the idea of papal infallibility had been a PR disaster. What it actually meant was that, on matters of faith, followers should accept somebody has got to be the boss, the final authority. It’s not like he has a magic power, that God whispers the truth in his ear, he said — via Warren Ellis

Robot Muscle

Usually the only alcohol-powered muscles are the ones in barroom brawls, but one scientist is adding alcohol to artificial muscles to power robots and more. Scientists at the University of Texas at Dallas have developed artificial muscles — science’s best attempt at mimicking natural muscles. But they’re not made with the hydraulics or gears that power most of today’s big, strong machines. These muscles are made of an elastic metal called shape memory wire
