Researchers create first molecule-blocks key component of cancer genes' on-off switch (September 24, 2010) -- In the quest to arrest the growth and spread of tumors, there have been many attempts to get cancer genes to ignore their internal instruction manual. In a new study, a team of scientists has created the first molecule able to prevent cancer genes from "hearing" those instructions, stifling the cancer process at its root. ... > full story
New map offers a global view of health-sapping air pollution (September 24, 2010) -- In many developing countries, the absence of surface-based air pollution sensors makes it difficult, and in some cases impossible, to get even a rough estimate of the abundance of a subcategory of airborne particles that epidemiologists suspect contributes to millions of premature deaths each year. ... > full story
New findings on multiple sclerosis: Immune cells also attack neurons directly (September 24, 2010) -- Researchers in Germany have gained new insight into how the immune system causes damage associated with multiple sclerosis, an incurable neuroinflammatory disorder. Using imaging tools which enable investigation of processes in living organisms, the scientists show a direct interaction between immune cells and neurons which plays a significant role in neuronal injury. ... > full story
Psychological pain of Holocaust still haunts survivors (September 24, 2010) -- Holocaust survivors show remarkable resilience in their day-to-day lives, but they still manifest the pain of their traumatic past in the form of various psychiatric symptoms, according to an analysis of 44 years of global psychological research. ... > full story
Botulinum toxin may offer temporary drooling relief in children with neurological disorders (September 24, 2010) -- Botulinum toxin treatment appears to offer a temporary, short-term solution to relieve drooling in children diagnosed with certain neurological disorders, according to a new study. ... > full story
Stress can control our genes, researchers find (September 24, 2010) -- Researchers in Denmark have shown that stress-factors can control our genes. Exposing human cells to a stress-activating compound turned on genes that are normally silenced. Protective complexes that prevents our genes from being read and translated into protein, where lost when the cells experienced stress. The consequence is that genes that should be turned off are now active and this may disturb cellular development, identity and growth. ... > full story
Cancer researchers discover new signaling pathway that controls cell development and cancer (September 24, 2010) -- Researchers have discovered a new cell signaling pathway that controls cell growth and development, a pathway that, when defective, helps promote the formation of several major forms of human cancer, including lymphoma and leukemia. ... > full story
Can't focus? Maybe it's the wrong time of month, finds estrogen study on attention and learning (September 24, 2010) -- Feeling a little sluggish and having trouble concentrating? Hormones might be to blame according to new research. The study shows that high estrogen levels are associated with an inability to pay attention and learn -- the first such paper to report how this impediment can be due to a direct effect of the hormone on mature brain structures. ... > full story
Phantom limbs more common than previously thought (September 24, 2010) -- A study of post-stroke patients reveals that the phantom-limb phenomenon may not be a rare event. ... > full story
Bioreactor could improve treatment for children with 'water on the brain' (September 24, 2010) -- A recent study could help find ways to improve shunt systems used to treat the neurological disorder hydrocephalus, or "water on the brain," the leading cause of brain surgery for children in the United States. Researchers studied the shunt systems under a variety of conditions by creating a bioreactor that mimics the environment inside patients. ... > full story
Video gaming prepares brain for bigger tasks (September 24, 2010) -- Playing video games for hours on end may prepare your child to become a laparoscopic surgeon one day, a new study has shown. Reorganization of the brain's cortical network in young men with significant experience playing video games gives them an advantage not only in playing the games but also in performing other tasks requiring visuomotor skills. ... > full story
New gene associated with increased risk of Alzheimer's disease (September 24, 2010) -- Researchers have identified a gene that appears to increase a person's risk of developing late-onset Alzheimer disease, the most common type of the disease. Abbreviated MTHFD1L, a gene on chromosome six, was identified in a genome-wide association study. ... > full story
