Scientists at the University of Georgia have created a "superfoam" with two very valuable potential applications. It could be used not only to clean up oil spills, but also to keep infections from occurring at medical implant sites.

As anyone who has grown climbing plants will know, the things are great at grasping onto thin objects such as strings or bamboo poles. A new robotic gripper, inspired by such plants, could find use in the handling of small, delicate items.

As we rapidly approach the limitations of Moore's Law, researchers investigate nanoscale technologies and alternatives to silicon. One group of researchers has turned to nature for an answer and produced the world's first DNA-based diode.
