    In search of nature’s camouflage

    Cuttlefish, the “chameleon of the sea,” may offer researchers a model for bio-inspired human camouflage and color-changing products, some of which could be invaluable in wartime.

    Needle beam stays on point

    A Harvard-led team of researchers has demonstrated a new type of light beam that propagates without spreading outward, remaining very narrow and controlled along an unprecedented distance. It could greatly reduce signal loss for on-chip optical systems and may eventually assist the development of a more powerful class of microprocessors.
