New research demonstrates that previous models used to examine cancer may not be complex enough to accurately mimic the true cancer environment. Using oral cancer cells in a three-dimensional model of lab-made tissue that mimics the lining of the oral cavity, the researchers found that the tissue surrounding cancer cells can epigenetically mediate, or temporarily trigge

A new study by Rice University's Baker Institute for Public Policy illustrates a disconnect between government funding of biomedical research by young investigators and a novel standard by which to judge it: the Nobel Prize.

Despite years of trying to improve the number of women undergraduates in science and engineering, a new study shows most universities are failing. Not only are women lagging behind their male classmates, efforts to close the gap too often focus on students instead of faculty and institutional structures.

Throughout history, science and religion have appeared as being in perpetual conflict, but a new study by Rice University suggests that only a minority of scientists at major research universities see religion and science as requiring distinct boundaries.

Haiti and the global community should work together to build a robust science sector that can help the nation recover from last year's deadly earthquake, support future development, and improve the lives of Haiti's people, says a new AAAS report by Haitian and international scientists and educators.

Heart specialists at Johns Hopkins have figured out how a widely used pacemaker for heart failure, which makes both sides of the heart beat together to pump effectively, works at the biological level. Their findings may open the door to drugs or genetic therapies that mimic the effect of the pacemaker and to new ways to to use pacemakers for a wider range of heart failure patients.

Since the first television screens lit up our living rooms scientists have been studying its affect on young children. Now scientists in Ohio have compared mother-child communication while watching TV to reading books or playing with Toys to reveal the impact on children's development.

The use of stronger graduated driver licensing programs for 16- to 19-year old drivers in the U.S. that included restrictions on nighttime driving and allowed passengers were associated with a lower incidence of fatal crashes among 16-year old drivers, but a higher incidence among 18-year olds, according to a study in the September 14 issue of JAMA.

Scientific research may be in decline across the globe because of growing pressures to report only positive results, new analysis suggests.

Although Americans are increasingly tolerant of the open expression of a variety of views, the terrorist attacks of Sept. 11, 2001 have made most Americans reluctant to extend those freedoms to Muslim extremists, research released Aug. 25 by NORC at the University of Chicago shows.
