The Healthy Steps for Young Children Program, which added behavior and development services to pediatric practices, continued to benefit families more than two years after the intervention ended, according to a study by researchers from the Johns Hopkins Bloomberg School of Public Health. view more (2007-09-04)
Hap1 protein links circulating insulin to brain circuits that regulate feeding behavior in mice
Researchers have discovered how the protein Hap1, which is abundant in the brain's hypothalamus, serves as the link between circulating insulin in the blood and the neural circuitry that controls feeding behavior in mice. view more (2006-04-10)
Caffeine intake prevents risk taking after extreme sleep deprivation
Caffeine use prevents increased risk taking that occurs after several nights of total sleep deprivation. view more (2009-06-10)
Study finds connection between teenage violence and domestic violence
Researchers tracing the development of violent behavior have found a link between teenage violence and domestic violence. view more (2007-06-26)
Family ties provide protection against young adult sucidal behavior
Adolescents and young adults typically consider peer relationships to be all important. However, it appears that strong family support, not peer support, is protective in reducing future suicidal behavior among young adults when they have experienced depression or have attempted suicide. view more (2009-04-14)
Teen drug education also helps curb risky sexual behavior, study finds
School-based drug education programs for adolescents can have a long-term positive impact on sexual behavior in addition to curbing substance abuse, according to a new RAND Corporation study. view more (2009-04-30)

Fathers respond to teens' risky sexual behavior with increased supervision
Two-thirds of American teenagers have sex by the time they're 18. A new longitudinal study finds that when adolescents engage in risky sexual activity, fathers respond by increasing their efforts to supervise and monitor their children. view more (2009-05-15)

Researcher: Narcissistic bosses destroy morale, drive down bottom line
In recent years, the motivations of business leaders such as financier Bernard Madoff and former Enron CEO Ken Lay have come under increased scrutiny as a result of behavior that caused both their employees and the public considerable distress. view more (2009-08-10)
A sensory organ, not the brain, differentiates male and female behavior in some mammals
For years, scientists have searched in vain for slivers of the brain that might drive the dramatic differences between male and female behavior. view more (2007-08-06)
NIST method may help optimize light-emitting semiconductors
Physicists at JILA have demonstrated an ultrafast laser technique for "seeing" once-hidden electronic behavior in semiconductors, which eventually could be useful in more predictable design of optoelectronic devices, including semiconductor lasers and white light-emitting diodes. view more (2006-02-17)
The precise role of seminal proteins in sustaining post-mating responses in fruit flies
Successful reproduction is critical to pass genes to the next generation. In sexually reproducing organisms, sperm enter the female with seminal proteins that are vital for fertility. view more (2007-12-18)
Similar brain chemicals influence aggression in fruit flies and humans
Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in a wide variety of animals as well as in humans. Another brain chemical signal, neuropeptide Y (known as neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality... view more...

Aggressors Need Dopamine, and Victims Require Serotnin
The Novosibirsk researchers have managed to establish connection between mice's aggressive behavior, biochemical modifications in their brain and the genes that cause those modifications. view more (2004-12-06)
Hammering sheet metal into shape
The tool at the pressing plant resonantly pounds the sheet metal, ejecting the newly formed vehicle hood moments later. Although this operation runs like clockwork on the production line, it caused the developers of the metal-forming equipment many a headache, since sheet metal springs back (unbends elastically) when the press is opened. The... view more... (2003-02-20)
Two 'noses' are necessary for flies to navigate well
Animals and insects communicate through an invisible world of scents. By exploiting infrared technology, researchers at Rockefeller University just made that world visible. view more (2007-12-27)
Study supports validity of test that indicates widespread unconscious bias
In the decade since the Implicit Association Test was introduced, its most surprising and controversial finding is its indication that about 70 percent of those who took a version of the test that measures racial attitudes have an unconscious, or implicit, preference for white people compared to blacks. view more (2009-06-18)
Does Facebook usage contribute to jealousy in relationships?
The more time college students spend on Facebook, the more likely they are to feel jealous toward their romantic partners, leading to more time on Facebook searching for additional information that will further fuel their jealousy, in an escalating cycle that may become addictive. view more (2009-08-07)
Smoking, teens and their parents: New research
A new study found that adolescents were at the greatest risk of smoking when their parents began smoking at an early age and the parents' smoking quickly reached high levels and persisted over time. view more (2008-11-24)
