Embedded sensors gauge materials' inner states
News & Analysis  
11/29/2004   Post a comment
ensors developed by Elizabethtown College researchers could pave the way for next-generation materials that would be equipped with 50-ohm coaxial connections that engineers could "ping" to read out the material's internal state. The embedded capacitive sensors could be the cure for advanced processing of materials from carbon nanotube-reinforced composites to plain old concrete, enabling functions ranging from elaborate process control monitoring to simple electronic pop-up alerts that would go
Flip-flops push forward era of all-optical computing
News & Analysis

Optical flip-flops could enable a new breed of all-optical chips, from communications switches to full-fledged optical computers, according to the Cobra Research Institute at Eindhoven (Netherlands) University of Technology.
Smart dust made to 'escort' molecules to sensors
News & Analysis  
11/22/2004   Post a comment
Researchers have shown recently that magnetic silicon nanoparticles-smart dust-can act as chaperones, surrounding and herding rare sample molecules so that the samples navigate channels to microfluidic sensors without leaving any residue. Someday such chaperones might surround cancer cells and "escort" them to the exit.

The extrusion techniques currently used to manufacture thin optical fibers require an aperture of the same diameter as the created cable, but physicists at the University of Chicago believe they have found a better way.
Microfluidic chips come alive for medical research
News & Analysis  
11/15/2004   Post a comment
Microelectromechanical systems researchers are getting close to a complete "animal-on-chip" that would allow medical experiments now requiring live animals to be run in vitro on microfluidic chips.
Biochip neural network earns wings as research tool
News & Analysis  
11/1/2004   Post a comment
Living neurons taught to control an F-22 flight simulator may yield secrets that could not only demystify silicon-based artificial neural networks but also provide essential clues for understanding and treating neurological conditions, such as epilepsy, that result from malfunctioning neural circuitry.
