HEALTH DAILY: HEAD IMPACT FROM SINGLE SEASON OF HIGH SCHOOL PRODUCES MEASURABLE CHANGE IN BRAIN CELLS

Football has the highest concussion rate of any competitive contact sport, and there is growing concern -- reflected in the recent decrease in participation in the Pop Warner youth football program -- among parents, coaches, and physicians of youth athletes about the effects of subconcussive head impacts, those not directly resulting in a concussion diagnosis, researchers noted.

HEALTH TIPS: NUTURING DURIMG PRESCHOOL YEARS BOOSTS CHILD'S BRAIN GROWTH

New research at Washington University School of Medicine in St. Louis indicates children with supportive mothers during preschool experience a more significant increase in the volume of the hippocampus during the period from school age to adolescence. In contrast, kids whose mothers were less supportive during the preschool years had a less steep growth trajectory, even if their mothers became more supportive later. The researchers measured support and nurturing by monitoring and scoring videotaped interactions between mothers and their children.

SCIENCE DAILY: MAMMAL-LIKE REPTILES SURVIVED WITH MAMMALS

Tritylodontids are the last known family of near-mammalian reptiles, before mammals with features such as advanced hearing evolved. Researchers have uncovered dozens of fossilized teeth in Kuwajima, Japan and identified this as a new species of tritylodontid. This suggests that tritylodontids co-existed with some of the earliest mammal species for millions of years.
