Escherichia coli is a commonly used indicator organism for detecting the presence of fecal contamination in drinking water supplies. view more (2009-03-10)
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)
Gene controlling circadian rhythms may be involved in onset of bipolar disorder
Disrupt the gene that regulates the biological clocks in mice and they become manic, exhibiting behaviors similar to humans with bipolar disorder, UT Southwestern Medical Center researchers have found. view more (2007-03-20)
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)
Study examines substance abuse prevalence among teens receiving routine medical care
Approximately 15 percent of teens receiving routine outpatient medical care in a New England primary care network had positive results on a substance abuse screening test. view more (2007-11-06)
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)
Drug commonly used for alcoholism curbs urges of pathological gamblers
A drug commonly used to treat alcohol addiction has a similar effect on pathological gamblers - it curbs the urge to gamble and participate in gambling-related behavior, according to a new research at the University of Minnesota. view more (2008-06-16)
Yerkes researchers show early life nurturing impacts later life relationships
Researchers at the Yerkes National Primate Research Center, Emory University, have demonstrated that prairie voles may be a useful model in understanding the neurochemistry of social behavior. view more (2009-09-01)
Pregnancy and lactation may affect maternal behavior and coping skills
In the October 2006 issue of the journal Endocrinology, a collaborative research study by scientists at Cummings School of Veterinary Medicine at Tufts University and the University of Otago Medical School in Dunedin, New Zealand, shows that pregnancy and lactation in rodents produce long-term changes in hormone receptor actions in a mother's... view more...

Human behavior changes the number of strains of infectious diseases
Simple models predict that only one strain of an infectious disease can exist at one time, but observation suggests otherwise. view more (2006-07-27)
To deter a predator, kill its young!
Prey have evolved a suite of tricks to avoid falling victim to a predator. They may escape, hide, protect, become toxic/inedible or defend themselves. In principle, they could also scare the predator away, but this is risky when predators are big. Recent work led by a Dutch research team and published in the July issue of Ecology Letters revealed... view more... (2002-07-11)
It's a unisex brain with specific signals that trigger 'male' behavior
Research by Yale scientists shows that males and females have essentially unisex brains - at least in flies - according to a recent report in Cell designed to identify factors that are responsible for sex differences in behavior. view more (2008-05-01)
