Social interactions can alter gene expression in the brain, and vice versa

Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.

Impulse control area in brain affected in teens with genetic vulnerability for alcoholism

PITTSBURGH, Nov. 6 – A new study suggests that genetic factors influence size variations in a certain region of the brain, which could in turn be partly responsible for increased susceptibility to alcohol dependence.

Unusual use of toys in infancy a clue to later autism

(SACRAMENTO, Calif.) — Researchers at the UC Davis M.I.N.D. Institute have found that infants later diagnosed with autism exhibited unusual exploration of objects long before being diagnosed. Studying a group of children at high risk for developing autism, the researchers found that those eventually diagnosed with the disorder were more likely to spin, repetitively rotate, stare at and look out of the corners of their eyes at simple objects, including a baby bottle and a rattle, as early as 12 months of age.

Kidney transplantation provides cognitive benefits for patients with kidney disease

Individuals with kidney disease often suffer from cognitive impairment, but kidney transplantation can improve their mental performance, according to a paper being presented at the American Society of Nephrology's 41st Annual Meeting and Scientific Exposition in Philadelphia, Pennsylvania.

New protocol to help in testimony of child victims

Psychology Professor Mireille Cyr has adapted an interview protocol from the National Institute of Child Health and Human Development (NICHD) that will enable child victims of sexual abuse to provide better testimony in Quebec courts.

"This guide is based 30 years of research on how to best evoke memory in children," says Cyr. "Children have a tendency to avoid talking about sexual abuse because they don't always understand that there's a problem or sometimes they are emotionally attached to their aggressor."

Cooperation and synergy marks out road ahead for European software research

The need for close co-operation and synergy between all stakeholders in the European software industry and how this is being achieved was the major focus of a three-day event in Rotterdam on 'European competitiveness and well-being through ICT-based innovation'. The event from 21 to 23 October brought together the ITEA 2 EUREKA Cluster for software-intensive systems and services and ARTEMISIA the Association for R&D actors in Advanced Research & Technology for EMbedded Intelligence and Systems– the EU public-private partnership.

Is stuttering in our DNA?

Bruce Willis, Marilyn Monroe, and Carly Simon all suffered from stuttering.

Today, three million Americans do, too. Most are able to overcome the handicap, which afflicts 5% of all children ― but childhood suffering from stuttering can be traumatic, producing educational, social, and occupational disadvantages.

Pregnancy diabetes doubles the risk of language delay in children

Quebec City, November 6, 2008—Children born to mothers with pregnancy-related diabetes run twice the risk of language development problems, according to a research team directed by Professor Ginette Dionne of Université Laval's School of Psychology. Details of this discovery are published in the most recent issue of the scientific journal Pediatrics.

How women can improve their quality of life after breast cancer treatment

Opting for less damaging treatments, staying active and learning about the warning signs of lymphedema: that's how women with breast cancer can avoid developing chronic lymphedema, according to the German Institute for Quality and Efficiency in Health Care (IQWiG). Women can learn more about how to protect themselves from this common and distressing adverse effect of treatment as well as handle the condition at the Institute's website, www.informedhealthonline.org.

Top scientific meeting urges coordinated response to economic and environmental crises

A fix for the economy must address ecological threats, a top international scientific meeting here has urged. Human society is moving dangerously beyond the planet's natural limits in a striking parallel to the financial debt crisis. "We're running the planet like a subprime loan," Dr. Johan Rockström of the Stockholm Resilience Centre said. A coordinated response would reduce the risks of both kinds of crises in the future.

Minority patients discouraged from cancer screening by negative messages

PHILADELPHIA – New behavioral science research published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, found that constantly emphasizing the negative consequences of a lack of cancer screening among minorities can actually make them less likely to go for screening.

Multiple sclerosis research charges ahead with new mouse model of disease

November 6, 2008, Cambridge, UK –A new study highlights the role of a charge-switching enzyme in nervous system deficits characteristic of multiple sclerosis and other related neurological illness.

Age, race are among factors that influence carotid-surgery success

DALLAS – Nov. 6, 2008 – Advanced age and race are among the factors that can affect whether a patient dies or suffers a stroke after carotid-artery surgery, a UT Southwestern physician involved in a multicenter study has found.

Genetic study provides new insights into molecular basis of language development

Scientists have identified the first gene that is associated with a common childhood language disorder, known as specific language impairment (SLI). The gene – CNTNAP2 – has also been recently implicated in autism, and could represent a crucial genetic link between the two disorders.

Although most children acquire proficient spoken language almost automatically and with little conscious effort, a significant number develop unexplained difficulties in producing and understanding language. SLI is the most common such disorder, affecting up to 7% of pre-school children.

Pitt research identifies new target in brain for treating schizophrenia

PITTSBURGH--Research from the University of Pittsburgh could expand the options for controlling schizophrenia by identifying a brain region that responds to more than one type of antipsychotic drug. The findings illustrate for the first time that the orbitofrontal cortex could be a promising target for developing future antipsychotic drugs—even those that have very different mechanisms of action. The study will be published during the week of Nov. 3 in the online edition of the journal Proceedings of National Academy of Sciences, with a print version to follow.
