Asian women who consumed an average of 200 milligrams or more of caffeine a day — the equivalent of roughly two cups of coffee — had elevated estrogen levels when compared to women who consumed less, according to a study of reproductive age women by researchers at the National Institutes of Health and other institutions.

The risk of depression appears to decrease for women with increasing consumption of caffeinated coffee, according to a report in the September 26 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The research was carried out by Michel Lucas, Ph.D., R.D., from the Harvard School of Public Health, Boston, and colleagues.
A yet unidentified component of coffee interacts with the beverage’s caffeine, which could be a surprising reason why daily coffee intake protects against Alzheimer’s disease. A new Alzheimer’s disease mouse study by researchers at the University of South Florida found that this interaction boosts blood levels of a critical growth factor that seems to fight […]
From high-school students to surgeons, anyone who has pulled an all-nighter knows there is a price to be paid the next day: trouble focusing, a fuzzy memory, and other cognitive impairments. Now, researchers at Penn have found the part of the brain and the neurochemical basis for sleep deprivation’s effects on memory. Their research was […]
Christina Calamaro considers adolescence as more than just a transitional stage between childhood and adulthood. She sees it as an opportunity for positive change. “Adolescence is the last frontier before adulthood, a time when we can look at people’s lives and make real dedicated change,” says Calamaro, PhD, CRNP, assistant professor and director of the […]
Among the many differences between girls and boys, effects from caffeine, including physiological, behavioral, and subjective can be added to the list.

The publisher made the original accompanying commentary available for free. Check the end of this report for […]
Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why. Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee’s protective effect. A protein called sex hormone–binding globulin […]
