Medical researchers have identified a possible way to treat tumors while sparing nearby healthy tissue.

Researchers are aiming to stump drug counterfeiters with an edible 'security tag' embedded into medicine. To imitate the drug, a counterfeiter would have to uncrack a complicated puzzle of patterns not fully visible to the naked eye.

Children with elevated exposure to early life stress in the home and elevated prenatal exposure to air pollution exhibited heightened symptoms of attention and thought problems, according to researchers.
