Researchers who use the TeraGrid, the nation’s most comprehensive and advanced infrastructure for open scientific research, can now leverage the computing resources of a powerful, 2048-processor BlueGene/L system at the National Center for Atmospheric Research (NCAR).

NCAR plans to provide up to 4.5 million processor-hours of BlueGene/L computing annually to researchers who have received computing grants from the National Science Foundation (NSF).

The operational integration of TeraGrid with the BlueGene/L system, nicknamed “frost,” involved extensive preparation by NCAR’s Computational and Information Systems Laboratory (CISL).

Central Michigan University Research Corporation and Dendritic Nanotechnologies, Inc. have developed technology capable of absorbing toxic chemicals from ground water that could lead to a revolutionary ground water purification system.

The U.S. Department of Defense’s Strategic Environmental Research and Development Program has awarded CMU-RC and DNT a $1.3 million contract to refine the process using DNT's Priostar dendrimer-based nanotechnology.

The project focuses on a worldwide breakthrough that will result in a cost effective ground water purification system. Its anticipated commercial launch is set for September 2008.

A newly developed DNA vaccine appears safe and may produce beneficial changes in the brains and immune systems of individuals with multiple sclerosis, according to a new study.

In patients with multiple sclerosis (MS), the immune system attacks the myelin sheaths that protect nerve cells in the brain and spinal cord, according to background information in the article. The nerve cell’s axon, which transmits messages to other neurons, is eventually destroyed. The cause of MS is unknown, but evidence points to the involvement of immune cells and antibodies that recognize and attack specific substances in the myelin, such as myelin basic protein. Certain cytokines, small proteins produced by cells that trigger inflammation, also may play a role.

A major surprise emerging from genome sequencing projects is that humans have a comparable number of protein-coding genes as significantly less complex organisms such as the minute nematode worm Caenorhabditis elegans. Clearly something other than gene count is behind the genetic differences between simpler and more complex life forms.

Increased functional and cellular complexity can be explained, in large part, by how genes and the products of genes are regulated. A University of Toronto-led study reveals that a step in gene expression (referred to as alternative splicing) is more highly regulated in a cell and tissue-specific manner than previously appreciated and much of this additional regulation occurs in the nervous system.

Glaucoma is one of the most common causes of blindness worldwide. There are various types of glaucoma, all of which lead to damage in the optic nerve and progressive loss of vision.

Exfoliation glaucoma is caused by the buildup of fibrous deposits on the surfaces on the front of the eye. Between 10-20% of people over the age of 60 are believed to have some degree of exfoliation syndrome, and perhaps more than half of these individuals will go on to develop exfoliation glaucoma.

The progression of glaucoma can be slowed using various medications that promote the drainage of fluids from the eye and reduce pressure on the optic nerve. However, exfoliation glaucoma is often resistant to drug treatment.

Substance abuse increases among acculturated Hispanic immigrants, according to new research presented today by Oregon State University assistant professor Scott Akins at the American Sociological Association’s Annual Meeting in New York.

The study surveyed 6,713 adults in Washington – of which 1,690 persons identified themselves as “Hispanic.” It is the first of its kind in the Pacific Northwest.

Previous research on the effect of acculturation on drug use has been conducted in states with larger Hispanic enclaves such as California, Florida and the Southwest. In these states Hispanics are more likely to live in heavily concentrated ethnic communities, which may slow their acculturation or assimilation.
