Chemists and engineers at Harvard University have used nanowires in order to make a new type of V-shaped transistor small enough to be used for sensitive probing of the interior of cells. The new device is smaller than many viruses and about one-hundredth the width of the probes which are currently used to take cellular ... »

Computer engineers at Washington University in St. Louis have developed a device that resembles the medical version of a “Star Trek scanner” – a smart phone-compatible ultrasound probe that can image the human body. William D. Richard, WUSTL associate professor of computer science and engineering, and David Zar, research associate in computer science and engineering, ... »
