NASA’s new ion-propulsion system
NASA engineers have finished testing a new ion-propulsion system for earth-orbiting and interplanetary spacecraft. The system is more powerful and fuel-efficient than its predecessors, enabling it to travel farther than ever before.

I knew that processors–like castles–are made of sand. But I didn’t know they required stuff like ion implantation at more than 185,000mph, electroplating, and the creation of up to 20 metal layers of transistor connections in 500nm. (Pics)

Artificial versions of the eel’s electricity generating cells can be used as a power source for medical implants and other tiny devices, suggests a study.
The paper, according to NIST engineer David LaVan, says that there are at least seven different types of electrical channels in eels, each with several possible variables to tweak, such as their density in the membrane.
