  • NASA is working on a brain-computer interface that will read brain waves and muscles, and operate alongside standard controls, such as keyboards, mice and speech.
    Reading the brain; controlling the muscles

    A single neuron in the brain may deliver enough information to control a muscle. These results could eventually help bypass the spinal cord, allowing paralyzed people to control their own muscles.

  • Running short of copper, phosphorus, rare elements

    We need elements. Without phosphorus fertilizer, millions would starve. A shortage of copper means a shortage of electricity. And we’re importing more than 95% of the “rare-earth” elements needed for LCDs, cell phones and green energy. Is this smart?

  • Electric eye learns from animal eye!

    Lenses cannot project a perfect image on the flat back of a camera, so images are distorted at the edges. A revolutionary camera solves this problem by curving the light detector.
