Research suggests why scratching is so relieving
01-31-2008 · EurekAlert!In the first study to use imaging technology to see what goes on in the brain when we scratch, researchers at Wake Forest University Baptist Medical Center have uncovered new clues about why scratching may be so relieving -- and why it can be hard to stop. The work is reported online in the Journal of Investigative Dermatology, and will appear in a future print issue.

- HIV exploits competition among T-cells
10-16-2006 · EurekAlert!
New HIV research shows how competition among the human immune system's T cells allows the virus to escape destruction and eventually develop into full-blown AIDS. The study, slated to appear in Physical Review Letters, employs a computer model of simultaneous virus and immune system evolution. It also suggests a new strategy for vaccinating against the virus -- a strategy that the computer simulations suggest may prevent the final onset of AIDS.

- UI spatial cognition research explains explorers' limited ability to navigate
08-03-2007 · EurekAlert!
Historical reports suggest that when Magellan, Columbus and other explorers sailed from Europe to the New World 500 years ago, they navigated the open sea by imagining an island just over the horizon. If they kept track of where the "virtual island" was, they knew in which direction to sail in the open water. But new research from the University of Iowa suggests that people's ability to imagine virtual islands -- without any perceptual cues to help -- is quite limited.

- Study suggests estrogen deficiency can lead to obesity-induced high blood pressure after menopause
08-08-2007 · EurekAlert!
At menopause, women lose hormone protection against heart and kidney diseases, and are likely to become obese. A research team has tested the idea that estrogen deficiency in aged females may trigger the development of high blood pressure and obesity. The results of their study, using an animal model, suggest that estrogen depletion can have these effects.

- Insomnia patients often denied sleep treatment when they have mental health conditions
02-04-2008 · EurekAlert!
Patients with insomnia who are diagnosed with accompanying mental health ailments often are not prescribed medication that will help them sleep -- which could then make related anxiety or depression worse, new research suggests. Scientists examining treatment patterns for insomniacs say that their findings suggest that many doctors appear to be reluctant to prescribe sleep aids, even those that pose no risk of dependence, if patients also have depression, anxiety or mood disorders.

The chances of developing breast cancer are to some extent inherited, but important new findings suggest survival also runs in the family. Research published in the online journal Breast Cancer Research suggests that if a woman succumbs to breast cancer her daughters or sisters are over 60 percent more likely to die within five years if they develop the disease.

- Study questions 'one size fits all' approach when measuring income's effect on school readiness
02-07-2007 · EurekAlert!
Findings from an analysis of the Early Childhood Longitudinal Study suggest that race and ethnic identity should influence the approach used to measure the socio-emotional and pre-academic skills that contribute to school readiness. The ECLS is a nationally representative sample of over 21,000 Kindergarteners. The research suggests that the "one size fits all approach" used to measure parenting and stressors that relate to poverty and school readiness should be reconsidered.

- A black and white look at breast cancer mortality
02-21-2007 · EurekAlert!
Researchers suggest a reason for racial disparity in breast cancer survival rates. African and African American women are much less likely to survive breast cancer surgery than their white counterparts and far more likely to get the disease before the menopause. Previous research suggests that those who undergo surgery for the disease before the menopause are more prone to relapse.

- Scientists identify gene that may indicate predisposition to schizophrenia
01-24-2007 · EurekAlert!
In a study from the January issue of the American Journal of Human Genetics, a research team lead by Xinzhi Zhao and Ruqi Tang (Shanghai Jiao Tong University) present evidence that genetic variation may indicate predisposition to schizophrenia. Specifically, their findings identify the chitinase 3-like 1 gene as a potential schizophrenia-susceptibility gene and suggest that the genes involved in biological response to adverse conditions are likely linked to schizophrenia.
