WEDNESDAY, Dec. 13, 2017 -- Teens are more likely to behave badly -- lie, steal, vandalize, use drugs -- if they live in areas with heavy air pollution, a study of children living in greater Los Angeles suggests.
Younger kids exposed to increased levels of air pollution tended to have delinquency scores similar to teens three or four years older, the study authors said, though the study did not prove that pollution actually caused delinquent behavior.
MONDAY, Nov. 13, 2017 -- Encouraging new mothers to stick with breast-feeding may halve the already small risk that infants will develop eczema when they hit their teens, new research suggests.
And while the study also found no impact on teenage asthma risk, at least one U.S. pediatrician said other studies have supported the role of breast-feeding in potentially cutting a child's risk of developing allergies or asthma.
THURSDAY, Nov. 30, 2017 -- Teens fixated on their smartphones experience changes to their brain chemistry that mirror those prompted by addiction, a new study suggests.
Kids who compulsively used the internet or fiddled with their phones tended to have increased neurotransmitter activity in the anterior cingulate cortex, a region tied to the brain's systems of behavior reward, control of inhibition and mood regulation, a team of South Korean researchers found.
