Yearling horse auction to benefit equine research
...so are being conducted that utilize the horse as a model
for insulin resistance and skeletal development in ways that may prove beneficial to human medicine. The work views nutrition of the horse from the points of reproduction, growth, exercise physiology, and health, Staniar said. Research projects exami...

Talented sniffer: A receptor known for guiding sperm to egg plays a role in the nose
... In light of their findings, the authors propose a model
in which a single receptor protein helps perform diverse chemosensory functions in the nose as well as in sperm. It is tempting to speculate that in the future, "sniffing tests" could be employed as a diagnostic tool for fertility defects associated ...

Stanford researchers establish center for physics-based simulations of biological structures
...mulation toolkit to enable scientists worldwide to model
biological systems ranging from molecules to whole organisms. SimBioS is one of four new national centers endeavoring to build the biomedical computing infrastructure urgently needed to speed progress in biomedical research. The centers will create ...
Daphne Koller named MacArthur Fellow
...lished in Nature Genetics, applied a probabilistic model
to identifying modules of co-regulated genes and identified regulatory roles for several proteins whose functions had been previously uncharacterized. Koller received her bachelor's (1985) and master's (1986) degrees from the Hebrew University...
Protein energy profiles offer clues about amyloids
...ins are prone to misfold. "In designing a computer model
for protein folding, you can't take everything into account because there are too many variables," said Vijay Pande, assistant professor chemistry and of structural biology at Stanford University and founder of the Folding@Home distributed computing ...

human disease. The initial assembly is based on 3.3-fold coverage of the bovine genome and by 2005, a 6-fold sequence coverage will be achieved. Researchers can access the sequence data through the following public databases: GenBank ( www.ncbi...
Bugs in the gut could play key role in understanding human disease and drug toxicity
...searchers believe it will be possible to develop a model
for testing the body's response to disease, looking at how the microbes in the gut interact with each other, mammalian genes and other environmental factors to understand why some drugs work well in some people but not others. Professor Nicholson ad...

studies to explore mechanisms that link warming with aridity in the western U.S. In addition to the paper in Science , they also used the data to create a CD-ROM called the North American Drought Atlas, the first of its kind, providing a history of ...
Protein protecting brain from toxins also blocks some chemotherapy from reaching tumors
