- Carnegie Mellon uses new imaging technique to discover differences in brains of people with autism
10-23-2006 · EurekAlert!
Using a new form of brain imaging known as diffusion tensor imaging (DTI), researchers in the Center for Cognitive Brain Imaging at Carnegie Mellon University have discovered that the so-called white matter in the brains of people with autism has lower structural integrity than in the brains of normal individuals. This provides further evidence that the anatomical differences characterizing the brains of people with autism are related to the way those brains process information.

- Study finds minimal racial bias in charitable giving to victims of Hurricane Katrina
07-10-2007 · EurekAlert!
The perceived neediness of Hurricane Katrina victims is a better determinant of charitable giving than the victims' race, according to study by Christina M. Fong, research scientist at Carnegie Mellon University, and Erzo F.P. Luttmer, associate professor at Harvard University's Kennedy School of Government. The paper was published this month by the National Bureau of Economic Research.

- Stress contributes to range of chronic diseases, Carnegie Mellon psychologist says
10-09-2007 · EurekAlert!
In a review of the scientific literature on the relationship between stress and disease, Carnegie Mellon University psychologist Sheldon Cohen has found that stress is a contributing factor in human disease, and in particular depression, cardiovascular disease and HIV/AIDS. Cohen’s findings will be published in the Oct. 10 issue of the Journal of the American Medical Association (JAMA). The article was co-authored by Denise Janicki-Deverts of Carnegie Mellon and Gregory E. Miller of the University of British Columbia.

- Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily
07-25-2007 · EurekAlert!
Carnegie Mellon University scientists have made an important discovery that helps to explain why HIV enters immune cells with ease. They found that after HIV docks onto a host cell, it dramatically lowers the energy required for a cell membrane to bend, making it easier for the virus to infect immune cells. The finding will provide vital data to conduct future computer simulations of HIV dynamics to help further drug discovery and prevent deadly infections.

- Carnegie Mellon scientist plays key role in unveiling sea urchin genome
11-09-2006 · EurekAlert!
Carnegie Mellon University has played a key role in an international, multi-institutional collaboration to sequence the sea urchin genome. As part of the consortium, Charles Ettensohn, professor of biological sciences, led the team that cataloged the genes responsible for building the sea urchin's embryonic skeleton. He also contributed 51,000 cDNAs -- about one-third of the total genomic material critical for assembling the genome and for accurately predicting where genes lie within the DNA sequence.

- Carnegie Mellon algorithm identifies top 100 blogs for news
11-19-2007 · EurekAlert!
Being among the first to pick up on Internet news and gossip and rapidly detecting contamination anywhere in a water supply system are similar problems, at least from a computer scientist's point of view. Both can be solved with a versatile algorithm developed by Carnegie Mellon University researchers.

- Theoretical physicists develop test for string theory
01-24-2007 · EurekAlert!
For decades, many scientists have criticized string theory, pointing out that it does not make predictions by which it can be tested. Now, researchers at Carnegie Mellon University; the University of California, San Diego; and The University of Texas at Austin have developed a test of string theory. Their test, described in the January 26 Physical Review Letters, involves measurements of how elusive high-energy particles scatter during particle collisions.

- DNA gets new twist: Carnegie Mellon scientists develop unique 'DNA nanotags'
01-26-2007 · EurekAlert!
Carnegie Mellon University scientists have married bright fluorescent dye molecules with DNA nanostructure templates to make nanosized fluorescent labels that hold considerable promise for studying fundamental chemical and biochemical reactions in single molecules or cells. The work, published online Jan. 26 in the Journal of the American Chemical Society, improves the sensitivity for fluorescence-based imaging and medical diagnostics.
