Carnegie Mellon University research shows how sensory-deprived brain compensates
04-17-2007 · EurekAlert!
Whiskers provide a mouse with essential information. These stiff hairs relay sensory input to the brain, which shapes neuronal activity. In a first, studies of this system by Carnegie Mellon scientists show just how well a mouse brain can compensate when limited to sensing the world through one whisker. Published April 4 in the Journal of Neuroscience, the results should help shape future studies of sensory deprivation that results from stroke or traumatic brain injury.

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.

'Less is more' online
07-09-2007 · EurekAlert!
Researchers at the University of Missouri-Columbia have found that less is more when it comes to online content. In a study that examined responses to pictures viewed online, the researchers found that people were able to pay more attention to pictures selected from a small array of choices than from a large array of choices. These findings may have implications for Internet search engines, advertising and news sites.
