UCI scientists reconstruct migration of avian flu virus

...o the next," said Robert Wallace, UCI postdoctoral researcher and lead author of the study. "By spreading across a large area, the virus in essence can run multiple experiments in multiple locations, increasing the likelihood that it will mutate into a form that can be transmitted from human to human." Avian...

Scientists identify molecular cause for one form of deafness

Snell of the School of Education and Social Policy and the Institute for Policy Research at Northwestern University. “In addition, our results suggest that encouraging parents to put younger children to bed earlier and allowing both younger ...

Soft-cell approach cuts animal tests

...of using human cell lines and cultures is that the researcher can study toxicity mechanisms at the molecular/cellular level at an earlier stage specifically for individual chemicals, depending on their site of action within the human body without using animals. For example, when assessing the toxicity of formal...

Nanotechnology meets biology and DNA finds its groove

...sy," says David C. Schwartz, a UW-Madison genomics researcher and chemist and the senior author of the PNAS paper. "And in order to read the molecule, you have to present the molecule." To attack the problem, Schwartz and his colleagues turned to nanotechnology, the branch of engineering that deals with the ...

When your brain talks, your muscles don't always listen

...scles to move, according to University of Delaware researcher Christopher Knight, an assistant professor in UD's College of Health Sciences. "As a result of age-related changes in muscle and neurons, elderly people are often frustrated by poor control during precision tasks, and slowed physical responses con...

Synthetic peptide targets latent papilloma virus infections
