Carnegie Mellon project boosts book digitization efforts
05-24-2007 · EurekAlert!A Carnegie Mellon University computer scientist is enlisting the unwitting help of thousands, if not millions, of Web users each day to eliminate a technical bottleneck that has slowed efforts to transform books, newspapers and other printed materials into digitized text that is computer searchable.

- Neuronal circuits able to rewire on the fly to sharpen senses
12-16-2007 · EurekAlert!
Researchers from the Center for the Neural Basis of Cognition, a joint project of Carnegie Mellon University and the University of Pittsburgh, have for the first time described a mechanism called "dynamic connectivity," in which neuronal circuits are rewired "on the fly" allowing stimuli to be more keenly sensed. The process is described in a paper in the January 2008 issue of Nature Neuroscience, and now available online.

- High blood pressure worsening in all states for women; begins to stagnate for men
02-11-2008 · EurekAlert!
Uncontrolled hypertension rates in men and women vary across the country, but all states -- especially in the south and including the nation's capital -- should boost blood pressure control efforts, researchers report in Circulation: Journal of the American Heart Association.

- Pittsburgh-based team engineers muscle, bone cell differentiation with aid of ink-jet printer
12-10-2006 · EurekAlert!
A team of researchers from Carnegie Mellon University and the University of Pittsburgh has created and used an innovative ink-jet system to print "bio-ink" patterns that direct muscle-derived stem cells from adult mice to differentiate into both muscle cells and bone cells. The results, which could revolutionize the design of replacement body tissues, will be presented Sunday, Dec. 10 at the 46th annual meeting of the American Society for Cell Biology in San Diego.

- NASA-funded robotic sub finds bottom of world's deepest sinkhole
05-31-2007 · EurekAlert!
A robotic vehicle designed for underwater exploration plunged repeatedly into the depths of Mexico's mysterious El Zacatуn sinkhole in late May, finding its previously undiscovered bottom 318 meters below the surface and generating a sonar map of its inner dimensions. The vehicle employed autonomous navigation and mapping systems developed by Carnegie Mellon University's Robotics Institute.

- Databases must balance privacy, utility, says Carnegie Mellon statistics professor
08-30-2007 · EurekAlert!
Agencies like the US Census Bureau produce a voluminous amount of data, much of which is of tremendous value to researchers. But the data also includes personal information that could be harmful were it to fall into the wrong hands. Thus, organizations that maintain such databases need to devise ways to protect individuals' privacy while preserving the value of the information to researchers, writes Carnegie Mellon University Statistics Professor George Duncan in a commentary in the Aug. 31 edition of the journal Science.

- Cancer vaccines -- Taking a jab at cancer by stimulating the immune system
04-17-2007 · EurekAlert!
As the first FDA-approved cancer vaccine, designed to protect against human papillomavirus, has moved from scientific discussion to social debate, other vaccine studies are continuing to make progress. While HPV vaccine efforts had the "benefit" of a viral source for the disease, other researchers are developing vaccines for cancers that are not virally based, in an effort to coax the immune system into attacking cancerous cells.

- Second phase of HapMap project is completed
10-17-2007 · EurekAlert!
Investigators from six countries have completed the second phase of the International HapMap Project, an effort to identify and catalog genetic similarities and differences among populations around the world. Information provided in the first phase of the HapMap, completed in 2005, has led to the development of techniques facilitating the search for genes associated with common diseases -- such as schizophrenia and heart disease -- and the identification of more than 50 such disease-associated genes.

- Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine
04-15-2007 · EurekAlert!
Experimental vaccines to help the immune system fight tumors have rarely been designed to directly stimulate helper T cells, one of the body's most critical immune responders, because of the difficult process required to isolate and clone antigens for vaccine development. Now, a new technique may allow scientists to create a melanoma vaccine able to stimulate helper T cells. The approach may also aid in the development of other vaccines against cancers or infectious diseases.
