New study examines memory, learning and aging
08-20-2007 · EurekAlert!In a recent Psychology and Aging study funded by the National Institute on Aging, Dr. John Dunlosky, Kent State professor of psychology and associate editor of Journal of Experimental Psychology: Learning, Memory and Cognition, and colleagues examined whether aging affects metacomprehension, or the ability to judge your own comprehension and learning of text materials.

- Cortex area thinner in youth with Alzheimer's-related gene
04-23-2007 · EurekAlert!
A part of the brain first affected by Alzheimer's disease is thinner in youth with a risk gene for the disorder, a brain imaging study has found. A thinner entorhinal cortex may render these youth more susceptible to degenerative changes and mental decline later in life. This learning and memory hub is thinner in youth with the Alzheimer's-releated ApoE4 variant of the apolipoprotein gene, perhaps lowering the threshold for adverse consequences with aging-related tissue loss.

- Education does not protect against age-related memory loss, say USC researchers
01-09-2007 · EurekAlert!
Adults over 70 with higher levels of education forgot words at a greater rate than those with less education, according to a new study from the University of Southern California. The findings, published in the current issue of Research on Aging, suggest that after age 70, educated adults may begin to lose the ability to use their schooling to compensate for normal, age-related memory loss.

- Public school kindergarteners post same or greater gains as private school counterparts
11-28-2006 · EurekAlert!
In the first study to examine differences in learning gains at the kindergarten level, William Carbonaro (University of Notre Dame) finds that publicly schooled kindergarteners post the same or greater learning gains as privately schooled kindergarteners. These findings come as a surprise. As Carbonaro writes, "Both the financial costs of private schooling and other self-selection factors ensure that the private schools will have a more advantaged population of students than public schools."

- Heavy, chronic drinking can cause significant hippocampal tissue loss
10-24-2006 · EurekAlert!
The hippocampus, a brain structure vital to learning and memory, is likely vulnerable to damage from heavy and chronic alcohol consumption. A new study has found a reduction in total hippocampus volume among alcoholics. This suggests that heavy drinking can cause significant hippocampal tissue loss.

- St. Jude study shows genes play an unexpected role in their own activation
06-22-2007 · EurekAlert!
Investigators at St. Jude Children's Research Hospital have discovered how a single molecular "on switch" triggers gene activity that might cause effects ranging from learning and memory capabilities to glucose production in the liver.

- Special ES&T issue examines effects of emerging contaminants on people, planet
11-30-2006 · EurekAlert!
More than 40 scientific papers on an array of emerging contaminants -- including pharmaceuticals, detergent by-products and fluorochemicals -- are highlighted in the Dec. 1 issue of the American Chemical Society journal, Environmental Science & Technology. These articles examine what chemists and engineers are learning about emerging contaminants as well as what can be done to remediate those already in the environment and prevent others from getting there.
