Meningitis in infancy is associated with teen behavioural problems
Infants who contract meningitis grow into teenagers with worse behavioural problems than their peers, suggests a study in the Archives of Disease in Childhood. The research team carried out a survey of the parents and teachers of 739 English and Welsh 13 year olds who had contracted bacterial... view more (2003-04-23)

Positive parenting associated with less aggression in early-maturing teen girls
Adolescent girls who go through puberty early and have parents who do not nurture them, communicate with them or have knowledge of their activities appear more likely to display aggressive behavior, according to a report in the August issue of Archives of Pediatrics & Adolescent Medicine, one... view more (2008-08-05)

Inside college parties: surprising findings about drinking behavior
Most studies of drinking by college students have focused on individual factors like attitudes, and have relied on self reports. A uniquely designed study instead had researchers visit college parties, gathering data on the spot. Findings revealed that drinking games and themed parties are... view more (2008-01-04)

Mothers' second-hand smoke exposure linked to psychological problems for kids
Children whose mothers were exposed to second-hand smoke while they were pregnant have more symptoms of serious psychological problems compared to the offspring of women who had no prenatal exposure to smoke, according to a new University of Washington study.   view more (2007-06-28)

Mothers' second-hand smoke exposure linked to psychological problems for kids
Children whose mothers were exposed to second-hand smoke while they were pregnant have more symptoms of serious psychological problems compared to the offspring of women who had no prenatal exposure to smoke, according to a new University of Washington study.   view more (2007-06-28)

Disabling a sensory organ prompts female mice to act like male mice
By short-circuiting the sensory organ that detects the chemical cues mice use to attract mates, a team of Howard Hughes Medical Institute (HHMI) researchers has prompted female mice to behave like male mice in the throes of courtship.   view more (2007-08-06)

1 missing gene leads to fruitless mating rituals
Male fruit flies missing a gene for one particular odor receptor become clueless in matters of love, scientists at Duke University Medical Center have discovered.   view more (2008-07-24)

Plants tell caterpillars when it's safe to forage
The world is filled with cues that could influence the daily feeding patterns of an organism. Many plants, for example, respond to foraging damage by releasing specialized chemical signals-volatile organic compounds that evaporate in the air-that attract the forager's natural enemies.   view more (2006-05-16)

Voluntary exercise does not appear to alleviate anxiety and depression
Voluntary physical activity does not appear to cause a reduction in anxiety and depression, but exercise and mood may be associated through a common genetic factor, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals.   view more (2008-08-05)

R rating might be unlikely to affect teens exposure to smoking in movies
Several recent research studies published in the United States have determined that young adolescents who see smoking scenes in movies are more likely to smoke.   view more (2007-09-28)

'Deviancy training' among friends may lead to more trouble
Friendships can be beneficial, but watch out when talk about deviant topics is the best way to get a laugh in an adolescent relationship, because such interaction may well lead to questionable behavior down the road, say University of Oregon researchers.   view more (2007-10-01)

Suprising discovery may lead to new understanding of water quality
Scientists at the U.S. Department of Energy's Argonne National Laboratory have discovered new ways that ions interact with mineral surfaces in water, opening a door to new knowledge on how contaminants travel in the environment. The insight, leads to a better understanding of the factors that... view more (2006-07-12)

Chronic Alcohol Exposure Can Affect Brain Protein Expression
Researchers at the University at Buffalo studying the effects of alcohol on the brain, using zebrafish as a model, have identified several novel central nervous system proteins that are affected by chronic alcohol exposure.   view more (2006-08-30)

Robots can learn from their mistakes
In the near future, intelligent, automated robots will help us in a number of different fields, such as transports, cleaning, mining, and agriculture. These robots will steer themselves without human involvement and will plan their own tasks. This makes great demands on safety, so that people,... view more (2004-09-10)

Early parenting plays key role in infants' physiological response to stress
In infancy, genes are the key influence on a child's ability to deal with stress. But as early as 6 months of age, parenting plays an important role in changing the impact of genes that may put infants at risk for responding poorly to stress.   view more (2008-09-16)

Researchers at UCLA engineering discover theoretical model to predict jamming
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have come up with a theoretical model to predict when granular materials become jammed.   view more (2008-04-28)

Social interactions can alter gene expression in the brain, and vice versa
Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.   view more (2008-11-07)

New candidate genes for schizophrenia identified
Schizophrenia is a severe psychiatric disease characterized by disorganized behavior, delusions and hallucinations. Sadly, there is no clear understanding of its cause.   view more (2008-10-21)

Parental conflict may affect children's behavior and learning by disrupting their sleep
For years, researchers have known that children who grow up in homes with high levels of conflict tend to have behavior and learning problems.   view more (2006-02-10)

Alarming rise in Israeli road deaths after terror attacks shown by Hebrew University and Princeton researchers
Terror attacks in Israel produce an alarming though temporary rise in the number of people killed in road accidents, a study conducted by Hebrew University of Jerusalem and Princeton University researchers has found.   view more (2004-09-26)

Nuclear physicists examine oxygen's limits
Physicists at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University have made a unique measurement of an exotic oxygen nucleus, leading scientists one step closer to deciphering the behavior of the element at its limits of existence.   view more (2007-09-14)

Tissue stiffness drives tumor formation
The relationship between tissue rigidity and tumor formation is fairly well established; however, what is not so well understood is what happens on a molecular level that contributes to such stiffness.   view more (2005-09-23)

Rutgers physicists show how electrons 'gain weight' in metal compounds near absolute zero
Rutgers University physicists have performed computer simulations that show how electrons become one thousand times more massive in certain metal compounds when cooled to temperatures near absolute zero - the point where all motion ceases.   view more (2007-11-02)

Forsyth scientists trigger cancer-like response from embryonic stem cells
Scientists from The Forsyth Institute, working with collaborators at Tufts and Tuebingen Universities, have discovered a new control over embryonic stem cells' behavior.   view more (2008-10-14)

Children and teens taking antidepressants might be more likely to attempt, complete suicide
Antidepressant medications may be associated with suicide attempts and death in severely depressed children and adolescents but not in adults.   view more (2006-08-08)
