DNA is the blueprint of all life, giving instruction and function to organisms ranging from simple one-celled bacteria to complex human beings. Now Northwestern University researchers report that they have used DNA as the blueprint, contractor and construction worker to build a three-dimensional structure out of gold, a lifeless material.

Brown University has joined forces with more than a dozen research universities and historically black colleges and universities (HBCUs) to promote robotics and computer science education for African-American students.

The continuous fabrication of complex, three-dimensional nanoscale structures and the ability to grow individual nanowires of unlimited length are now possible with a process developed by researchers at the University of Illinois.Based on the rapid evaporation of solvent from simple “inks,” the process has been used to fabricate freestanding nanofibers, stacked arrays of nanofibers and continuously wound spools of nanowires.

Preventative heart healthcare gains strong momentum as NightHawk Radiology Holdings, Inc. (Nasdaq: NHWK), has announced its involvement as the exclusive radiology provider for the High-Risk Plaque Initiative (”HRP Initiative”).

Then you spot a familiar landmark like the Tower of London and suddenly you have your bearings”New research from the University of Bristol shows for the first time that global positioning systems technology (GPS) can be used to show how children as young as three find their way around.

A discovery by scientists at the Carnegie Institution has opened the door to a new generation of piezoelectric materials that can convert mechanical strain into electricity and vice versa, potentially cutting costs and boosting performance in myriad applications ranging from medical diagnostics to green energy technologies.

Neurological surgeons at Jefferson Hospital for Neuroscience are among the first surgeons in the United States using an FDA-approved liquid system for treating wide-necked brain aneurysms, which could eventually replace current treatments.Principal investigator Erol Veznedaroglu, M.D.

Results published in FASEB (the journal of the Federation of American Societies for Experimental Biology) by researchers at Columbia University, including Jeremy Mao of the Columbia College of Dental Medicine, demonstrate a novel way of using porous structures as a drug-delivery vehicle that can help boost the integration of host tissue with surgically implanted titanium.

Medtronic, Inc. (NYSE: MDT) announced the FDA approval of a new physician-use continuous glucose monitoring (CGM) system, the CGMS® iPro™ Recorder. Physicians send patients home with the CGMS iPro Recorder to uncover patterns and potential problems that often go undetected with today’s standard glucose measurements like finger stick meters and HbA1c tests. The new CGMS iPro Recorder is smaller, lighter in weight and less time consuming to use than previous CGMS recorders.

Sicel Technologies, Inc. announced that CMS (Centers for Medicare and Medicaid Services) has established a new HCPCS code (Healthcare Common Procedure Coding System) that became effective on January 1, 2008, for implantable radiation dosimeters.
