Duke Engineering Contest Connects U.S. Students with National Problems
DURHAM, N.C. — Duke University’s Pratt School of Engineering challenges college students in the U.S. to create a video and an essay in response to this question: Which of the 14 grand challenges identified by the National Academy of Engineering would you choose to address, and how would you do it? The National Academy of Engineering Grand Challenges (http://www.engineeringchallenges.org) has identified 14 critical barriers to a sustainable way of life. They represent problems that will require … August 28, 2008
‘Virtual’ Mouse Brains Now Available Online
July 9, 2007
A multi-institutional consortium including Duke University has created startlingly crisp 3-D microscopic views of tiny mouse brains — unveiled layer by layer — by extending the capabilities of conventional magnetic resonance imaging. “These images can be more than 100,000 times higher resolution than a clinical MRI scan,” said G. Allan Johnson, Duke’s Charles E. Putman Distinguished Professor of radiology and professor of biomedical engineering and physics. He is first author of a report describing the innovations set for publication in the research journal NeuroImage. Images on the website for Duke’s Center for In Vivo Microscopy , which Johnson directs, reveal examples of these innovations in action. In one video two different mouse brains — one from a normal animal and the other from a rodent missing a gene linked to mental abnormalities — seem to assemble themselves before the viewer’s eyes, structure by structure.
