Low levels of neurotransmitter serotonin may perpetuate child abuse across generations

Infant abuse may be perpetuated between generations by changes in the brain induced by early experience, research shows. A research team found that when baby rhesus monkeys endured high rates of maternal rejection and mild abuse in their first month of life, their brains often produced less serotonin, a chemical that transmits impulses in the brain. Low levels of serotonin are associated with anxiety and depression and impulsive aggression in both humans and monkeys.

   06-29-2007 · EurekAlert!
   Researchers state that "alcohol-abuse prevention must consist of locating and identifying genetically predisposed subjects." The research reveals that a subject's brain with low beta-endorphin levels becomes accustomed to the presence of an exogenous surplus, diminishing its own supply and triggering dependence on an external source -- in this case, alcohol.

5. What makes a good leader -- the assertiveness quotient
   02-04-2007 · EurekAlert!
   Organizational leaders who come across as low or high in assertiveness tend to be seen as less effective, according to a study coming out in the February issue of the Journal of Personality and Social Psychology, published by the American Psychological Association. Leaders in the middle may have an "optimal" level of assertiveness, but there is plenty of company on the extremes. The research suggests that being seen as under- or over-assertive may be the most common weakness among aspiring leaders.

   08-28-2007 · EurekAlert!
   New Kaiser Permanente study shows treating gestational diabetes can break the link to childhood obesity. The largest study of its kind, this research shows that childhood obesity risk rises with a pregnant woman's blood sugar level and untreated gestational diabetes doubles a child's risk of obesity. Authors looked at 20,000 mothers and children, and found treating gestational diabetes lowers the child's risk of obesity to same level of a mother with normal blood sugar levels.

7. 'Noah's flood' kick-started European farming
   11-18-2007 · EurekAlert!
   The flood believed to be behind the Noah's Ark myth kick-started European agriculture. This research paper assesses the impact of the collapse of the North American (Laurentide) Ice Sheet, 8,000 years ago. The results indicate a catastrophic rise in global sea level led to the flooding of the Black Sea and drove dramatic social change across Europe. The research team argues that, in the face of rising sea levels driven by contemporary climate change, we can learn important lessons from the past

8. Children's perceptions of their parents' antisocial behavior may lead them to be antisocial
   02-07-2007 · EurekAlert!
   A recent study to examine how antisocial behavior is transmitted across generations found that children's perceptions of their parents' behavior may be key in the development of these behaviors. Researchers looked at 430 adolescents and their biological parents across the child's high school years. The findings reflect that since parent behavior gives children a model for their own behavior, perceiving that a parent is antisocial may give a child permission to engage in similar behaviors.

Therefore, researchers caution that government and education policymakers need to consider the appropriate grade levels and related impact before trying to create overall homework policies for schools.
