Problem-Solving Governs How We Process Sensory Stimuli

June 25, 2013 11:28 am | by University of Zurich | News | Comments

Various areas of the brain process our sensory experiences. How the areas of the cerebral cortex communicate with each other and process sensory information has long puzzled neuroscientists. Exploring the sense of touch in mice, brain researchers from the University of Zurich demonstrate that the transmission of sensory information from one cortical area to connected areas depends on the task to solve and the goal-directed behavior.

Breakthrough in Nanodevice Biosensors

June 24, 2013 12:07 pm | by Yale | News | Comments

Imagine a swarm of tiny devices only a few hundred nanometers in size that can detect trace amounts of toxins in a water supply or the very earliest signs of cancer in the blood. Now imagine that these tiny sensors can reset themselves, allowing for repeated use over time inside a body of water – or a human body.

Device Detects Disease with Drop of Blood

June 24, 2013 10:48 am | by New Jersey Institute of Technology | News | Comments

An NJIT research professor known for his cutting-edge work with carbon nanotubes is overseeing the manufacture of a prototype lab-on-a-chip that would someday enable a physician to detect disease or virus from just one drop of liquid, including blood.

Assessing Performance of Colonoscopy Procedures Improves Quality

June 24, 2013 10:10 am | by American Society for Gastrointestinal Endoscopy | News | Comments

A new study reports that the use of a quarterly report card is associated with improved colonoscopy quality indicators. Endoscopists at the Roudebush Veterans Affairs Medical Center in Indianapolis, Ind., who participated in the study showed an overall adjusted adenoma (precancerous polyp) detection rate increase from 44.7 percent to 53.9 percent, and a cecal intubation rate increase from 95.6 percent to 98.1 percent.

Simulating Solutions for Molding Challenges

June 21, 2013 4:18 pm | by Tim Lankisch, Director of Engineering, CAE Services | CAE Services Corporation, Arburg Gmbh + Co Kg | Articles | Comments

Design and development of a medical device is an exacting process, to say the least, and it assumes even more complexity because it almost always extends across years that encompass multiple iterations of the device. As a result, small things that were satisfactory in the prototype and first production run can grow to be problems that must be solved as production volume rises.
