Carbon nanofibers hold promise for technologies ranging from medical imaging devices to precise scientific measurement tools, but the time and expense associated with uniformly creating nanofibers of the correct size has been an obstacle – until now. A new study from North Carolina State University demonstrates an improved method for creating carbon nanofibers of specific sizes, as well as explaining the science behind the method.(more…)
GAINESVILLE, Fla. — Oral disease occurs commonly and progresses rapidly among people who have HIV, but the process is poorly understood. Researchers suspect that the culprit is a change in the makeup of bacterial communities that live in the mouth.(more…)

Over 50 percent of the population in the United States and over 60 percent in the world live in coastal areas. Rapidly growing human populations near the ocean have massively altered coastal water ecosystems. (more…)
EAST LANSING, Mich. — A punch. A kick. A hit in the head with a can of soda. It’s not a Three Stooges film but rather the latest trend in advertising, a trend a Michigan State University professor calls “disturbing.”(more…)
ANN ARBOR, Mich.— While exposed spent fuel rods at the failing nuclear reactors in Japan pose new threats, the worst-case scenario would still be unlikely to expose the public to catastrophic amounts of radiation, says a University of Michigan nuclear engineering professor who is an expert on this particular kind of reactor.
“For the public, I don’t believe it would be much higher than two additional chest x-rays,” said John Lee, a professor in the Department of Nuclear Engineering and Radiological Sciences, citing the results of the Three Mile Island accident. (more…)
