...obot," said Stephen Smith, professor of biomedical engineering at Duke's Pratt School of Engineering. Smith and Eric Pua, a Pratt graduate student who participated in the research, reported the findings in the cover article of the November 2006 issue of the journal IEEE Transactions on Ultrasonics, Ferroelectr...

Iowa State researchers improving plastics made from corn and soy proteins

...State assistant professor of materials science and engineering who's also working on the project. Those clay platelets need to be separated and mixed evenly throughout the plastic to be much good as a reinforcing agent. The researchers are turning to high-powered ultrasonics ?high-frequency sound waves too hi...

Electronic chip, interacting with the brain, modifies pathways for controlling movement

...Mavoori, who recently earned a Ph.D. in electrical engineering from the UW, and Dr. Eberhard Fetz, professor of physiology and biophysics. For many years Fetz and his colleagues have studied how the brains of monkeys control their limb muscles. When awake, the brain continuously governs the body's voluntary mo...

Stormy days ahead for coral reefs

Swogger is headed to Oregon State University for a Ph.D. Secor is pursuing a Ph.D. at MSU. One of the center's strengths is its unique i...

New biochip helps study living cells, may speed drug development

...rfield, a professor of agricultural and biological engineering who leads the team developing the chip. The device works by measuring the concentration of ions -- tiny charged particles -- as they enter and exit cells. The chip can record these concentrations in up to 16 living cells temporarily sealed within ...

Zinc plays important role in brain circuitry

...ain and spinal cord add a new key player: zinc. By engineering a mouse with a mutation affecting a neuronal zinc target, researchers have demonstrated a central role for zinc in modulating signaling among the neurons. Significantly, they found the mutant mouse shows the same exaggerated response to noise as chil...

Researchers examine why food tastes bad to chemotherapy recipients

...Virginia Tech professor of civil and environmental engineering (CEE). Dietrich believes there are two components to the metallic flavor –?the taste of metal ions on the tongue and the production of metal-catalyzed odors in the mouth that create a retro-nasal effect. "I am attempting to gain a better understan...

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...ven without humans aboard, is a monumentally risky engineering feat. Since 1998, the United States has completed seven Mars missions. Four failed when the Mars landers were lost on arrival. As part of a new push to put a man on Mars, NASA has sketched out a roadmap laying out 45 risks to astronauts in a space ...

Cardiologist's 'living chip' changes science of disease monitoring
