Environmental injustice in people-of-color communities is as much or more prevalent today than 20 years ago, say researchers commissioned to conduct a follow-up to the 1987 landmark study, "Toxic Wastes and Race in the United States."

Immune cells that are the body’s front-line defense don’t necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought.

Research finds calorie-dense dessert recipes printed in major newspapers across the country may be contributing to obesity in large cities. The study, conducted by researchers at Marshfield Clinic Research Foundation, Marshfield, Wis., is published in the latest issue of the Wisconsin Medical Journal (Volume 106, No. 2).
