Transport Behavior of E. coli Varies Depending on Manure Source
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)

Breast stem cells have features similar to 'basal' tumors
The most aggressive form of breast cancer may originate from breast stem cells that have undergone genetic mishaps.   view more (2006-07-20)

Neurotransmitters signal aggressive cancer, offer potential for early diagnosis
Nerves talk to each other using chemicals called neurotransmitters. One of those "communication chemicals," aptly named GABA (gamma amino butyric acid), shows up in unusually high amounts in some aggressive tumors, according to a new study from Washington University School of Medicine in St. Louis.   view more (2005-07-05)

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)

When ants attack: Researchers recreate chemicals that trigger aggression in Argentine ants
Experiments led by researchers at the University of California, Berkeley, have demonstrated that normally friendly ants can turn against each other by exploiting the chemical cues they use to distinguish colony-mates from rivals.   view more (2009-10-28)

Breast cancers behave differently before and after the age of 70
Researchers in Belgium have discovered that increasing age affects the way breast cancer behaves. As women approach the age of 70, they become less likely to be diagnosed with aggressive tumours that have spread to the lymph nodes. But after 70, the cancer is increasingly likely to spread, particularly if the tumours are small.   view more (2008-04-21)

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)

Herceptin and chemo improves response rates without major adverse effects in HER2 breast cancer
Women with a particularly aggressive form of breast cancer seem to do better if they are treated with a combined anthracycline and taxane chemotherapy regimen before surgery, together with trastuzumab (Herceptin) before and after surgery, according to results from the largest multi-centre trial to investigate this treatment.   view more (2008-04-18)

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)

Long-term tamoxifen use increases risk of an aggressive, hard to treat type of second breast cancer
While long-term tamoxifen use among breast cancer survivors decreases their risk of developing the most common, less aggressive type of second breast cancer, such use is associated with a more than four-fold increased risk of a more aggressive, difficult-to-treat type of cancer in the breast opposite, or contralateral, to the initial tumor.   view more (2009-08-26)

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)

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...

Exercise helps overweight children reduce anger expression
Regular exercise seems to reduce anger expression in overweight but otherwise healthy children, researchers said.   view more (2008-11-25)
