COLUMBIA, Mo. – As the need for engineering professionals grows, educators and industry leaders are increasingly concerned with how to attract women to a traditional male career. A new University of Missouri study found the impact of the engineering curriculum and obstacles, including self-efficacy and feelings of inclusion, can impede women's success in the predominantly male discipline of engineering.

"New blood" can revitalize a company or a sports team. Recent research by Tel Aviv University finds that young blood does a body good as well, especially when it comes to fighting cancer.

The Transcendental Meditation technique may be an effective and safe non-pharmaceutical aid for treating ADHD, according to a promising new study published this month in the peer-reviewed online journal Current Issues in Education.

The pilot study followed a group of middle school students with ADHD who were meditating twice a day in school. After three months, researchers found over 50 percent reduction in stress and anxiety and improvements in ADHD symptoms.

NEW YORK – Maintaining blood sugar levels, even in the absence of disease, may be an important strategy for preserving cognitive health, suggests a study published by researchers at Columbia University Medical Center (CUMC). The study appeared in the December issue of Annals of Neurology.

NASHVILLE, Tenn.--For risk-takers and impulsive people, New Year's resolutions often include being more careful, spending more frugally and cutting back on dangerous behavior, such as drug use. But new research from Vanderbilt finds that these individuals--labeled as novelty seekers by psychologists--face an uphill battle in keeping their New Year's resolutions due to the way their brains process dopamine.

MAYWOOD, Ill. -- Moderate drinkers often have lower risks of Alzheimer's disease and other cognitive loss, according to researchers who reviewed 44 studies.

In more than half of the studies, published since the 1990s, moderate drinkers of wine, beer and liquor had lower dementia risks than nondrinkers. In only a few studies were there increased risks.

Jerusalem, December 28, 2008 – Scientists at the Hebrew University of Jerusalem have succeeded in reversing brain birth defects in animal models, using stem cells to replace defective brain cells.

The work of Prof. Joseph Yanai and his associates at the Hebrew University-Hadassah Medical School was presented at the Tel Aviv Stem Cells Conference last spring and is expected to be presented and published nest year at the seventh annual meeting of the International Society for Stem Cell Research in Barcelona, Spain.

In a recently conducted study, a multidisciplinary French-American research team with expertise in archaeology, past climates, and ecology reported that Neanderthal extinction was principally a result of competition with Cro-Magnon populations, rather than the consequences of climate change.

AMES, IA—A survey of employers in the landscape industry revealed the importance of arming landscaping and horticulture students with technical knowledge, practical application, and problem-solving skills. Teaching students the skills necessary to solve complex landscape management decisions is crucial to their career success.

(SACRAMENTO, Calif.) — UC Davis Cancer Center researchers report today the discovery of a molecule that targets glioblastoma, a highly deadly form of cancer. The finding, which is published in the January 2009 issue of the European Journal of Nuclear Medicine and Molecular Imaging, provides hope for effectively treating an incurable cancer.

Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org).

Effect exceeds expectations

SAN FRANCISCO, Dec. 29, 2008 -- Facial expressions of emotion are hardwired into our genes, according to a study published today in the Journal of Personality and Social Psychology. The research suggests that facial expressions of emotion are innate rather than a product of cultural learning. The study is the first of its kind to demonstrate that sighted and blind individuals use the same facial expressions, producing the same facial muscle movements in response to specific emotional stimuli.

A research group lead by scientists at the University of Warwick has discovered the trigger that pulls together X chromosomes in female cells at a crucial stage of embryo development. Their discovery could also provide new insights into how other similar chromosomes spontaneously recognize each other and are bound together at key parts of analogous cell processes. This is an important mechanism as the binding togetgher of too many of too few of a particular chromosome can cause a number of medical conditions such as Down's Syndrome or Turner's Syndrome.

DALLAS – Dec. 24, 2008 – Anxiety disorders in children and adolescents should be recognized and treated to prevent educational underachievement and adult substance abuse, anxiety disorders and depression, says a nationally recognized child psychiatrist from UT Southwestern Medical Center.
