 Scientists have gained new insight into why a relatively short-term hearing deprivation during childhood may lead to persistent hearing deficits, long after hearing is restored to normal. The research reveals that, much like the visual cortex, development of the auditory cortex is quite vulnerable if it does not receive appropriate stimulation at just the right time. Read more »

 High school and college students who understand the geological age of the Earth (4.5 billion years) are much more likely to understand and accept human evolution, according to a new study. A 2009 Gallup poll reported that 16 percent of biology teachers believe God created humans in their present form at some time during the last 10,000 years. Read more »

Tags: Boot, Game, According
 According to new findings, owning a video-game system may hamper academic development in some children. Boys who received a video-game system immediately had significantly lower reading and writing scores after four months than boys receiving a video-game system at the end of the experiment. Further analysis revealed that the time spent playing video games may link the relationship between owning a video-game system and reading and writing scores. Read more »

 Bad behavior in childhood is associated with long-term, chronic widespread pain in adult life, according to the findings of a study following nearly 20,000 people from birth in 1958 to the present day. The research found that children with severe behavior disturbances had approximately double the risk of chronic widespread pain by the time they reached the age of 45 than children who did not have behavior problems.

 Although it's typically considered an adolescent curse, ADHD actually affects about five percent of adults as well. New research in a mouse model of attention deficit/hyperactivity disorder suggests that the root of the psychiatric disorder might be the over-activity of a protein that regulates dopaminergic pathways. The work suggests a path toward new treatments for symptoms including inattentiveness, over-activity and impulsivity. Read more »
