Researchers are developing a new class of tiny mechanical devices, made up of vibrating structures the thickness of a human hair, that could be used to filter electronic signals in cell phones and other applications. Only the size of a grain of sand, these microelectromechanical systems (MEMS) will, nonetheless, improve performance and reduce power usage. Read More

An artificial knee costing just USD$20 promises to deliver much needed help to amputees who are disadvantaged or impoverished – particularly when the price of high-end titanium knee joints can range anywhere from USD$10,000 to USD$100,000. The artificial knee, dubbed the JaipurKnee, was developed by Joel Sadler, a lecturer in mechanical engineering and d'Arbeloff Fellow, and his team at the Hasso Plattner Institute of Design at Stanford University.
