lecithin writes "Spaceflightnow has a story regarding a puzzle to astronomers and geologists. What makes mars magnetic? If you could pick up a rock from the surface of Mars, then the chances are it would be magnetic. And yet, Mars doesn't have a magnetic field coming from its core. These rocks are clinging to the signal of an ancient magnetic field, dating back billions of years, to the times when Mars had a magnetic field like Earth's."

Submitted by

Gugo writes "German based company FESTO had develop a bionic arm. The difference? It uses muscles emulation, with a product called "fluidic muscle". Is like a normal animal-human muscle but moved instead of blood by air running inside. The capabilities of this muscle are rapid response,small size,very simple to assembly and easy to control. Also in the website they show fluidic muscles in gamers application with a car race simulator. It seems at comparative low cost against similar devices. Films of this applications you can find there.
