Two professors at Cold Spring Harbor Laboratory (CSHL) have succeeded in tracing intricate biochemical networks involving a class of proteins that enable genes to express themselves in specific tissues at particular moments in development.

Manipulating embryo-derived stem cells before transplanting them may hold the key to optimizing stem cell technologies for repairing spinal cord injuries in humans. Research published in BioMed Central's open access Journal of Biology, may lead to cell based therapies for victims of paralysis to recover the use of their bodies without the risk of transplant induced pain syndromes.
Researchers in Rochester, N.Y., and Colorado have shown that manipulating stem cells prior to transplantation may hold the key to overcoming a critical obstacle to using stem cell technology to repair spinal cord injuries.
Denver, CO, and Durham, NC -- A pregnant mouse's diet can induce epigenetic changes that increase the risk her offspring will develop allergic asthma, according to researchers at National Jewish Health and Duke University Medical Center. Pregnant mice that consumed diets high in supplements containing methyl-donors, such as folic acid, had offspring with more severe allergic airway disease than offspring from mice that consumed diets low in methyl-containing foods. The results of the study are being published Sept.
The bonds that tie a mother to her newborn may be stronger in women who deliver naturally than in those who deliver by cesarean section, according to a study published by Yale School of Medicine researchers in the October issue of Journal of Child Psychology and Psychiatry.
Leuven, Belgium – Our brain consists of billions of cells that continually transmit signals to each other. This dynamic process − which enables us to learn, remember, and so much more − works only when the brain cells make contact correctly, or, in other words, when there is a good 'synapse'. An essential element in this process is a controlled protein production along with the synapse.
COLUMBUS, Ohio – Researchers have identified specific damages to the brain that may occur when heart attack victims are socially isolated from others.
The study in mice found that those animals that lived alone before undergoing a heart attack showed five to eight times more damage to neurons in one part of the brain than did similar animals that lived with others.
A new study has found that parental control directly influences whether a child will develop a harmonious or obsessive passion for their favorite hobby. Conducted by Professor Geneviève Mageau, of the Université de Montréal's Department of Psychology, the study will be published this fall edition of the Journal of Personality.
AMES, Iowa – Mothers, take note. If you really want to curb your teens' chances of using alcohol, help them develop a self-view that doesn't include drinking. According to a new Iowa State University study, the power of positive thinking by moms may limit their children's alcohol use.
But beware. The opposite is also true.
RICHMOND, Va. (Sept. 18, 2008) – Virginia Commonwealth University School of Medicine researchers have uncovered how sodium is able to control specific potassium ion channels in cells, according to new study findings published online this week in Nature Chemical Biology.
These findings, published Sept. 14, may help researchers gain a greater understanding of the mechanisms involved in ion channel gating and may one day set the stage for new approaches in drug design.
New Brain Imaging Shows The Effects of Withdrawal on Smokers Trying to Quit and How Therapeutic Nicotine Helps
An audio relaxation program lowered blood pressure more than a Mozart sonata in a group of elderly people with high blood pressure, researchers reported at the American Heart Association's 62nd Annual Fall Conference of the Council for High Blood Pressure Research.
In a study of 41 elderly participants at three retirement facilities:
In an effort to curb the rising rates of HIV and sexually transmitted infections (STIs) along the Mexico-US border, a binational team of researchers led by the University of California, San Diego School of Medicine have shown that brief but personalized behavioral counseling significantly reduced rates and improved condom use among female sex workers in Tijuana and Ciudad Juarez, Mexico.
CLEVELAND—Mangled bodies, gunfire, high-speed chases and injured children are just a few events witnessed by police officers and soldiers serving in dangerous hot spots around the world.
The city of Cleveland's Division of Police has partnered with Case Western Reserve University, the Partnership for a Safer Cleveland and the U.S. Department of Defense to reduce on-the-job stress among police officers, who find themselves in the middle of these traumatic events.
Montreal, September 17, 2008 – Kids and teens surrounded by overweight peers or parents are more likely to be oblivious to their own extra pounds than kids from thin entourages, according to a new study by researchers from the Université de Montréal, McGill University, Concordia University and the Ste. Justine Hospital Research Centre.
