Michel Maharbiz and his colleagues at the University of California, Berkeley, are developing implants for giant beetles that allow scientists to control the insects’ flight. Researchers hope that the beetles can one day be used for search and rescue or reconnaissance in areas inaccessible to people or other robots.
The paper diagnostic chips are made in a few steps, shown here by graduate student Andres Martinez, a member of the Whitesides Research Group.
George Whitesides explains how diagnostic paper chips could revolutionize health care in disparate places.
Zhong Lin Wang, a professor of materials science at Georgia Tech, describes his work on nanoscale devices that convert mechanical energy into power for the nano world.
A solar test field in Masdar City will help determine what zero-emissions technologies will work best in the heat and dust of the desert.
Gerard Evenden, the senior partner at the U.K.-based firm Foster and Partners, who developed the master plan for Masdar City, explains how he will save energy.
Lasers and a century-old dye could supplant needles and thread.
A new surgical technique, developed by scientists at the Rehabilitation Institute of Chicago, allows patients who have lost arms to use residual nerve signals to control a prosthetic limb. This video shows three patients testing a prototype limb being developed by DARPA. The patients can perform complex tasks, including picking up a cup, grasping a cracker without breaking it, and putting a spoon in a cup.
