The link between climate and cholera, a serious health problem in many parts of the world, has become stronger in recent decades, say researchers from the University of Michigan, the University of Barcelona and the International Center for Diarrhoeal Disease Research in Bangladesh.

Their research will be published in the online version of the Proceedings of the National Academy of Sciences this week.

In a previous study published in the journal Science, the researchers found eviden

Research on an AIDS-like disease in monkeys continues to help scientists understand problems such as how HIV causes AIDS, how the virus “hides” from the immune system and how the disease might be prevented or treated, two decades after the human and monkey diseases were identified.

“These animals have been indispensable for understanding how the virus works and in working toward vaccines,” said Murray Gardner, professor emeritus of medical pathology at the UC Davis Center for Comparative Me

USDA Forest Service plant pathologists have discovered a new cause of damage to loblolly pine seedlings grown in the South – needle nematodes. In the July 2002 issue of Plant Disease, pathologists Stephen Fraedrich (SRS Insects and Diseases of Southern Forests unit in Athens, GA) and Michelle Cram (Forest Health Protection Program, Region 8) report on finding a previously undescribed species of nematode stunting the growth of pine seedlings in a Georgia nursery.

In 1998, a three-year study w

Some bottles of wine are worth thousands of dollars. But if oxygen has leaked past the cork, it could be thousand-dollar vinegar — and there’s no way to tell without opening the bottle. Now chemists at the University of California, Davis, can check an unopened bottle for spoilage using nuclear magnetic resonance (NMR), the same technology used for medical MRI scans.

Natural bacteria in wine use oxygen from the air to turn alcohol into vinegar, or acetic acid. If a wine bottle is secur

Like tiny Russian dolls, the mealybugs that infest your houseplants carry bacteria inside their cells that are themselves infected with another type of bacteria. A new study by researchers at the University of California, Davis, shows that instead of spreading from bug to bug, the second set of bacteria infected the first several times in the past and are now being passed along and evolving with them.

The knowledge could be useful for working out how the insect species are related to each o

Rush is one of only two sites in nation testing the drug that may provide new treatment option

Physicians at Rush-Presbyterian St. Luke’s Medical Center have begun to recruit patients as part of a clinical research study that will evaluate the effectiveness of a new drug as a potential treatment for fragile X syndrome and autism.

The trials are taking place at Rush and the University of California, Davis. The principal investigators in the study are Dr. Elizabeth Berry-Krav
