The ability to monitor the activities of ensembles of single neurons is critically important in understanding the principles of information processing in the brain that underlie...
Briefs: Software
Historically, the subjective nature of wound treatment has lead to many trial-and-error therapies to match wounds with the right treatment. The WoundMatrix™ digital wound measurement and tracking...
Applications: Medical
When conducting a surgical procedure, doctors typically administer anesthetics to block all sensation for the patient, including pain and distress. Based on the type of procedure,...
Applications: Manufacturing & Prototyping
Ultra-fine shaped wire, frequently one-tenth the thickness of a typical human hair, is the basis of critical components in many medical instruments. Minute defects in such wire can lead to...
Mission Accomplished: Electronics & Computers
For companies that do not need NASA-developed technology or advanced test facilities but still want to leverage some of the brain power of NASA’s engineering teams to solve a design problem in their product,...

PocketChart™, available in numerous medical specialty editions, is a wireless, handheld electronic medical record application that will help physicians increase productivity, reduce...
Features: Robotics, Automation & Control
As human beings become more comfortable sharing their space with robots, we can expect that robotic technologies will infiltrate even more aspects of our lives. For the past decade or so,...
Briefs: Manufacturing & Prototyping
Progress has been made in continuing research on scaffolds for the guided growth of nerves to replace damaged ones. The scaffolds contain pores that are approximately cylindrical and...

Crashworthy Seats Would Afford Superior Protection
Seats to prevent or limit crash injuries to astronauts aboard the crew vehicle of the Orion spacecraft are undergoing development. The design of these seats incorporates and goes beyond crash-protection concepts embodied in prior spacecraft and racing-car seats to afford superior protection against...
Applications: Medical
Millions of people with diseases that starve eye tissue and nerves of oxygen may avoid blindness with a procedure developed by researchers at the U.S. Department of Energy’s Oak Ridge National...
Mission Accomplished: Medical
Conventional periodontal probing is indeed invasive, uncomfortable for the patient, and the results can vary greatly between dentists and even for repeated measurements by the same dentist....
