A biologist at Washington University in St. Louis and his collaborators have identified the factor in mammalian brain cells that keeps cells in synchrony so that functions like the wake-sleep cycle, hormone secretion and loco motor behaviors are coordinated daily over a 24-hour period.
Researchers from the Johns Hopkins Bloomberg School of Public Health and the Center for Micronutrient Research at Annamalai University in India report that the consumption of milk fortified with specific micronutrients — zinc, iron, selenium, copper, vitamin A, vitamin C and vitamin E — significantly reduces diarrhea and acute lower respiratory illness among children in developing countries.

Harvard scientists found people who ate bacon at least five times a week were 59% more likely to develop the bladder cancer than those who never did. The study appears in the American Journal of Clinical Nutrition.
Many people don’t fully understand the seemingly simple label instructions on their prescription medication, according to a Northwestern University study of low-income patients. Nearly half of the patients in the study misinterpreted at least one or more out of the five prescription labels they were shown. Patients with low literacy made the most mistakes, but even people with a high-school education and higher had problems. The reason is awkward wording, according to the researcher.
Researchers at Harvard Medical School’s Brigham and Women’s Hospital compared the effects of a variety of immunosuppressive agents on cardiovascular events in a large sample of RA patients.
Inactive enzymes entombed in tiny honeycomb-shaped holes in silica — nano-chambers that mimic conditions in living cells — can spring to life, scientists discovered while attempting salvaging enzymes that had been in a refrigerator long past their expiration date. The finding opens up new possibilities for exploiting these enzyme traps in food processing, decontamination, biosensor design and any other pursuit that requires controlling catalysts and sustaining their activity.
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 than privately schooled kindergarteners.
Recent studies and public discussions have focused on female achievement in math, and an important new study in the November issue of the American Journal of Education expands the literature to encompass racial disparity.
