- Alzheimer's prevention role discovered for prions
07-03-2007 · EurekAlert!
A role for prion proteins, the much debated agents of mad cow disease and vCJD, has been identified. It appears that the normal prions produced by the body help to prevent the plaques that build up in the brain to cause Alzheimer’s disease. The possible function for the mysterious proteins was discovered by a team of scientists led by Medical Research Council funded scientist Professor Nigel Hooper of the University of Leeds.

- Bacteria control how infectious they become, study finds
04-12-2007 · EurekAlert!
The results of a new study suggest that bacteria that cause diseases like bubonic plague and serious gastric illness can turn the genes that make them infectious on or off. Knowing how disease-causing bacteria, like Yersinia pestis and E. coli, do this may one day help scientists create drugs that control the expression of these genes, thereby making the bacteria harmless. The findings appear in the April 13 issue of the journal Molecular Cell.

- New research to help fight widespread potato disease
11-07-2007 · EurekAlert!
Scientists have made a key discovery into the genetics of the bacteria that causes blackleg, an economically-damaging disease of potatoes, that could lead to new ways to fight the disease. The researchers at the University of Cambridge, funded by the Biotechnology and Biological Sciences Research Council, found that if a particular gene is inactivated in the bacterium Erwinia carotovora, its ability to damage the plant and cause disease is severely impeded.

- Scripps scientists develop new tests that identify lethal prion strains quickly and accurately
12-04-2007 · EurekAlert!
Scientists at the Scripps Research Institute in Jupiter, Florida, have developed two new tests for prions, infectious proteins that cause a number of diseases including "mad cow disease," and a human counterpart, variant Creutzfeldt-Jakob disease. These advances open the door to better understanding and diagnosis of these troubling conditions.

- Skimmed milk -- Straight from the cow
05-28-2007 · EurekAlert!
Herds of cows producing skimmed milk could soon be roaming our pastures, reports Cath O’Driscoll in Chemistry & Industry, the magazine of the SCI. Scientists in New Zealand have discovered that some cows have genes that give them a natural ability to produce skimmed milk and plan to use this information to breed herds of milkers producing only skimmed milk.

- Cornell scientists link E. coli bacteria to Crohn's disease
08-07-2007 · EurekAlert!
A team of Cornell University scientists from the College of Veterinary Medicine, Weill Cornell Medical College and the College of Agriculture and Life Sciences have discovered that a novel group of E. coli bacteria -- containing genes similar to those described in uropathogenic and avian pathogenic E. coli and enteropathogenic bacteria such as salmonella, cholera and bubonic plague -- is associated with intestinal inflammation in patients with Crohn's disease in their research paper published July 12 by the ISME Journal: Multidisciplinary Journal of Microbial Ecology.

05-10-2007 · Massachusetts Institute of Technology (MIT)
Scientists at MIT and the Whitehead Institute have discovered small but critical regions within prions, infectious proteins that cause mad cow disease or its human equivalent, Creutzfeldt-Jakob disease, through the study of nontoxic yeast prions.

- Bacteria that cause urinary tract infections invade bladder cells
12-17-2007 · EurekAlert!
Scientists at Washington University School of Medicine in St. Louis have found definitive proof that some of the bacteria that plague women with urinary tract infections are entrenched inside human bladder cells. The finding confirms a controversial revision of scientists' model of how bacteria cause UTIs. Previously, most researchers assumed that the bacteria responsible for infections get into the bladder but do not invade the individual cells that line the interior of the bladder.

- Restless legs genetics on the move
07-19-2007 · EurekAlert!
Scientists from the Munich GSF Research Center for Environment and Health, the Technical University of Munich and the Max Planck Institute for Psychiatry have finally identified sequence variants in the genome, which are more frequent in RLS patients than in the normal population. For the first time ever this allowed insights into the underlying cause of this disease.
