New findings blow a decade of assumptions out of the water
01-10-2007 · EurekAlert!The Atlantic Ocean doesn't receive the mother lode of fixed nitrogen, the building block of life, after all. Instead, comparing fathom for fathom, the Pacific and Indian oceans experience twice the amount of nitrogen fixing as the Atlantic, say researchers in the January 11 issue of Nature. The title of an accompanying News and Views piece says it all, "Looking for N2 Fixation in all the Wrong Places."

- Negative press gives asylum seekers a bad name
11-09-2006 · EurekAlert!
The negative portrayal of asylum seekers in the press has a direct and immediate adverse impact on readers' assumptions about asylum seekers in general. A new study funded by the Economic and Social Research Council (ESRC) and conducted by a team of researchers at Thames Valley and Sussex Universities explored readers' thoughts and behaviors toward asylum seekers immediately after reading press coverage. Findings suggest that the effect of negative stereotypes is often unconscious and automatic, even among people with relatively low levels of prejudice.

- Toward a test for detecting in childhood the risk of developing bipolar disorder and schizophrenia
03-14-2007 · EurekAlert!
A team from Centre de recherche Université Laval Robert-Giffard (CRULRG) has made significant progress toward finding a way to determine whether a child is likely to one day suffer from bipolar disorder or schizophrenia. The findings of the research team supervised by Dr. Michel Maziade, director of CRULRG, professor in Université Laval’s Faculty of Medicine, and Canada Research Chair in the Genetics of Neuropsychiatric Disorders, will be presented at the International Congress on Schizophrenia Research on March 31 in Colorado Springs.

- Sex and prenatal hormone exposure affect cognitive performance, Yerkes scientists find
04-12-2007 · EurekAlert!
In one of the first research studies to assess sex differences in cognitive performance in nonhuman primates, researchers at the Yerkes National Primate Research Center have found the tendency to use landmarks for navigation is typical only of females. This finding corroborates findings in rodents and humans and is available in the online edition of Hormones and Behavior.

- Brain images show hysteria not an imaginary disorder
12-11-2006 · EurekAlert!
In what's being called a novel finding, researchers using brain scans have uncovered evidence of cerebral dysfunction in women with sensory conversion disorder, better known as hysteria. The study's findings open up a new window to understanding hysteria, an unexplained neurological disorder in which a patient complains of symptoms, but doctors can't find anything medically wrong with them. The study is published in the December 12, 2006, issue of the journal Neurology.

08-14-2007 · EurekAlert!
A new model of Saturn's icy moon Enceladus may quell hopes of finding life there. Developed by researchers at the University of Illinois, the model explains the most salient observations on Enceladus without requiring the presence of liquid water.

- Einstein researchers find that a commonly found contaminant may harm nursing infants
12-03-2007 · EurekAlert!
Scientists at the Albert Einstein College of Medicine of Yeshiva University have shown that perchlorate -- an industrial pollutant linked to thyroid ailments -- is actively concentrated in breast milk. Their findings suggest that perchlorate contamination of drinking water may pose a greater health risk than previously realized. The study appears in the Dec. 3-7 advance online issue of the Proceedings of the National Academy of Sciences.

- LIAI scientists make important finding on cytomegalovirus transmission
05-10-2007 · EurekAlert!
Researchers at the La Jolla Institute for Allergy & Immunology have shown that cytomegalovirus (CMV) in the salivary glands can be reduced -- and in some cases eliminated -- through the use of antibodies to enhance the disease-fighting power of the immune system. The research team's findings, based on controlled laboratory studies of mice, may also have implications for other chronic virus infections, such as hepatitis and HIV, the virus that causes AIDS.

- Evolutionary battle scars' identify enhanced antiviral activity
01-24-2008 · EurekAlert!
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center in Seattle. These findings, published Jan. 25 in the open-access journal PLoS Genetics, present a striking example by which evolutionary studies can directly lead to biomedically important discoveries in the field of infectious diseases.
