Researchers have discovered that nitric oxide is a powerful regulator of a molecule that plays a critical role in the development and function of the nervous system. The finding could someday play a significant role in the prevention and treatment of high blood pressure, which affects about one in three adults in the United States.
Brain tumor's 'grow-or-go' switch discovered
23:01 11-03-2010; source: www.sciencedaily.com
High energy levels cause glioblastoma cells to proliferate; low levels cause them to grow less and to migrate. This study discovered that a molecule called miR-451 coordinates this grow-or-go behavior, which is closely linked to the cells' ability to invade and spread. Thus, the molecule might be a biomarker for predicting survival in patients with glioblastoma multiforme and may serve as a target to develop drugs to fight these tumors.

Early detection is key to more effective treatment for Alzheimer's disease and other forms of cognitive impairment, and recent research shows that a new test is more than 95 percent effective in detecting cognitive abnormalities associated with these diseases.
Quantum dots spotlight DNA-repair proteins in motion

Repair proteins appear to efficiently scan the genome for errors by jumping like fleas between DNA molecules, sliding along the strands, and perhaps pausing at suspicious spots, say researchers who tagged the proteins with quantum dots to watch the action unfold.
Mother's flu during pregnancy may increase baby's risk of schizophrenia
