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,… »
