Data processing joins fight to treat cancer
Laboratory technicians battling cancer want to improve diagnosis and treatment of the disease. But they are drowning in data from modern biological techniques. New Web-based software - validated in three European oncology hospitals - can extract potentially life-saving knowledge from such data in minutes. view more (2005-04-06)
Food cue-related brain activity linked to obesity?
A unique pattern of gene expression observed in rats may be linked to a conditioned desire for food and excessive food intake, an article published today in BMC Biology suggests. view more (2007-04-27)
Purdue 'metamaterial' could lead to better optics, communications
Engineers at Purdue University are the first researchers to create a material that has a "negative index of refraction" in the wavelength of light used for telecommunications, a step that could lead to better communications and imaging technologies. view more (2005-12-01)
