Purchasing contact lenses online may save consumers time, but the process could cause more problems in the long run, according to a new study reported in the January issue of Optometry: Journal of the American Optometric Association. The research, conducted by Joshua Fogel, Ph.D., and Chaya Zidile of Brooklyn College, found that individuals who did not purchase their contact lenses from an eye doctor, but from an online site or store, are potentially placing themselves at greater risk. The findings indicated that online and store purchasers (consumers who get their contacts at a wholesale club or optical chain outlet) are less likely to adhere to healthy eye care practices, as recommended by their eye doctor.
According to the Contact Lens Institute (CLI), more than 30 million individuals wear contact lenses.

Spending just 10 minutes talking to another person can help improve your memory and your performance on tests, according to a University of Michigan study to be published in the February 2008 issue of the Personality and Social Psychology Bulletin.
“In our study, socializing was just as effective as more traditional kinds of mental exercise in boosting memory and intellectual performance,” said Oscar Ybarra, a psychologist at the U-M Institute for Social Research (ISR) and a lead author of the study with ISR psychologist Eugene Burnstein and psychologist Piotr Winkielman from the University of California, San Diego.
Daily alcohol use causes changes in sexual behavior, new study reveals

A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition. The research, which will be published on 2 January 2008 in the scientific journal PLoS ONE, resulted in four novel findings with broad importance for further addiction research. It is the first study to characterize the effects of chronic alcohol exposure in fruit flies.
“Physiological evidence supporting various theories about the effect of alcoholic drinks has been lacking, so our now having a suitable animal model makes it possible to conduct much-needed laboratory research on this issue,” explains research-team-leader Kyung-An Han, associate professor of biology and a neuroscientist at Penn State. Information from this research can serve as a baseline for similar studies in other animals, including humans.

With more menopausal women seeking natural therapies to ease symptoms, a new study has found that simply adding a brisk walking routine can reduce a variety of psychological symptoms such as anxiety, stress and depression. The research is published in the January issue of Cancer Epidemiology, Biomarkers & Prevention.
“With the aging population, physical activity represents one way for women to stay mentally healthy. Physical activity can help throughout the menopausal transition and afterwards,” said Temple University public health researcher Deborah Nelson, Ph.D, the study’s lead author.
