Oxidation processes basis of interdisciplinary research, graduate training

...n for high performance polymers," says Long. "This really gives us an opportunity to develop technologies that are not petroleum based." Food science graduate student Heather Woodson is determining which light waves cause oxidation in such packaged foods as milk, and student Janet Webster is evaluating poly...

Predators and human health

...till at a nascent stage. Furthermore, what is really more important than a rodent species' population per se, explains Ostfeld, is to understand how population dynamics drive rodent behavior which in turn influences disease transmission to humans.

Seeing the forest for the trees: The future of environmental policy lies in interaction

...id MSU's Jianguo "Jack" Liu. "Each policy may look really good, but if you put them together, they might have some unexpected negative impacts. We are learning to change the way we make policy, and the ways in which we evaluate policy." Liu told those attending the symposium "Frontiers in Biocomplexity Scie...

Computer scientists develop tool for mining genomic data

... very partial view,'' Koller says. What scientists really want to know is how groups of genes work together to control specific biological processes, such as muscle development or cancer progression. Unraveling these regulatory networks - for example, determining that Gene A gets activated by Gene B but rep...

HUPO scientists tackle human blood plasma proteome

... according to Gilbert S. Omenn, M.D., Ph.D. "If we really want to understand what genes are doing in cells, we have to focus on proteins - the effector molecules of the cell," says Omenn, a professor of internal medicine and human genetics in the University of Michigan Medical School and School of Public He...

Report details growing climate change threat to coral reefs

...cted to worsen with future climate changes. "We're really outside of any normal envelope that coral reefs have existed in," Kleypas says. "We haven't had carbon dioxide levels this high for thousands of years, maybe millions of years, and given the sensitivity of coral reefs to high temperature and ocean ac...

Out-of-balance ecosystems play role in demise of amphibian populations

However, the problems facing amphibian habitats really pose a poignant example of ecosystems out of balance because of human activity, according to Beasley, a professor of veterinary biosciences and executive director of the Envirovet Program in Wildlife and Ecosystem Health. Beasley's main collaborators...

Patients give nod to kidney dialysis at home

...uch higher than did hemodialysis patients. "This really speaks to the issue of whether patients are getting all the information they need upfront, in a thorough, comprehensive way, to choose the right treatment for them," says principal investigator Neil R. Powe, M.D., M.P.H., M.B.A., Director, of the Wel...

Woodpeckers: There's a fungus among us

...of wildlife. "Our study shows that woodpeckers are really the architects and landlords of the forest," said WCS scientist Kerry Farris, the study's lead author. "Their activities play a key role in how snags decay and are used by other species." Woodpeckers initially puncture dead and dying trees in search...

Research points in new direction for cancer clues

...a former member of the Moses lab, agreed. "This really suggests new causes of cancer and targets for intervention," Bhowmick said. "We were looking at TGF-beta because that's what we study. But it's likely that there are other molecules in the stroma (supporting cells) that are important, too, and this...

UT Southwestern researchers find leptin turns fat-storing cells into fat-burning cells

...pearance of a fat cell to a very novel cell that's really never been seen before. There's no precedent for a cell that appears like this. "The ability to convert fat cells into fat-burning cells may suggest novel therapeutic strategies for obesity." Dr. Unger and his collaborators began working on this rese...

"This calcium transporter really is an important key to understanding how the heart is regulated," said Dr. Donald Hilgemann, professor of physiology and senior author of the study. "At every beat, calcium in heart cells increases. And it's calcium that is the messenger to the heart...

New mode of action discovered for tamoxifen

...is. This has not been shown before. I think we can really use that information to improve treatment protocols." Although tamoxifen has been proven clinically effective at treating and, in some cases, preventing breast cancer, this drug has two significant problems. Long-term use of tamoxifen, like many othe...
