    Distributed light sensing Squid can really hide well in their environment. It is important for their survival since they have minimal active defenses but how is it important to us? Office of Naval Research thought that it was important enough to grant a $ 6 million grant to Roger Hanlon of Woods Hole Marine Biological…

  • Spider robot molded cheaply

    Byscientist

    Cheap robots by the millions Typically it costs many hundreds of dollars to make a robot that can do something substantial. However, researchers at the Fraunhofer institute have created molded or stamped robots that can be created very cheaply – they imagine them to be like disposable gloves. Make them, use them and then throw…

  • Fluorescent living cell produces laser

    Byscientist

    Harvard Wellman Center for Photo medicine’s two scientists, Gather and Yun, have shown that they can generate laser light from single cells. These HEK293 cells were transiently transfected with GFP. The expressed GFP (~300 microMolar) showed optical amplification of light. The cells had to placed in an artificial cavity and stimulated by external pulsed laser…
