An international team of scientists from the Moores Cancer Center at the University of California, San Diego, the University of North Carolina and several institutions in China have explained how a gene alteration can lead to the development of a type of brain cancer, and they have identified a compound that could staunch the cancer's growth.

A UQ researcher has revealed a new treatment for a speech disorder that commonly affects those who have suffered a stroke or brain injury.
PhD graduate Dr Rachel Wenke has shown in a recent study that the Lee Silverman Voice Treatment® may be an effective option for dysarthria patients suffering from stroke and traumatic brain injury (TBI).
Dysarthria is a speech disorder which negatively affects a person's ability to communicate as they can be difficult to understand and may sound like they have slurred or unclear speech.
(SACRAMENTO, Calif.) — In three new studies — including one appearing online today in the Public Library of Science - Biology (PLoS - Biology) — UC Davis researchers provide compelling evidence of how low levels of polychlorinated biphenyls (PCBs) alter the way brain cells develop.
The findings could explain at last — some 30 years after the toxic chemicals were banned in the United States — the associations between exposure of the developing nervous system to PCBs and behavioral deficits in children.
New therapeutic approaches in Alzheimer's disease are urgently needed. Work led by Professor Mark Pepys FRS over more than 20 years has identified a protein known as serum amyloid P component (SAP) as a possible therapeutic target in Alzheimer's disease. In collaboration with Roche he developed a new small molecule drug, CPHPC, which specifically targets SAP and removes it from the blood.
Individuals who take aspirin or other medications that prevent blood clotting by inhibiting the accumulation of platelets appear more likely to have tiny, asymptomatic areas of bleeding in the brain, according to a report posted online today that will appear in the June print issue of Archives of Neurology, one of the JAMA/Archives journals.
Abnormalities in the fibers connecting different brain areas may contribute to muscle disorders such as writer's cramp, according to a report in the April issue of Archives of Neurology, one of the JAMA/Archives journals.
COLLEGE PARK, Maryland, April 13, 2009 -- After about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles back and forth between the frenzied activity of rapid eye movement (REM) sleep and the quiet resting state of non-REM sleep. But whether the brains of younger, immature fetuses cycle with sleep or are simply inactive has remained a mystery, until now.
New research from Vanderbilt University has found students benefit more from being taught the concepts behind math problems rather than the exact procedures to solve the problems. The findings offer teachers new insights on how best to shape math instruction to have the greatest impact on student learning.
The research by Bethany Rittle-Johnson, assistant professor of psychology and human development at Vanderbilt University's Peabody College and Percival Mathews, a Peabody doctoral candidate, is in press at the Journal of Experimental Child Psychology.
Comparing different ways of solving math problems is a great way to help middle schoolers learn new math concepts, researchers from Vanderbilt and Harvard universities have found.
"We found that comparing different ways to solve a problem helped middle-school students become more flexible problem solvers and better understand the concepts behind the methods," Bethany Rittle-Johnson, assistant professor of psychology and human development at Vanderbilt University's Peabody College and co-author of the new research, said.
A recent study by Mount Sinai faculty suggests that a gene associated with onset of type-2 diabetes also decreases in Alzheimer's disease dementia cases. The research, led by Dr. Giulio Maria Pasinetti, MD, Ph.D., The Aidekman Family Professor in Neurology, and Professor of Psychiatry and Geriatrics and Adult Development at Mount Sinai School of Medicine, was published this week in the scientific journal, Archives of Neurology.
A test developed by physician-scientists at Washington University School of Medicine in St. Louis may help assess more quickly the ability of Alzheimer's drugs to affect one of the possible underlying causes of Alzheimer's disease in humans, accelerating the development of new treatments.
PITTSBURGH—The enchantingly colored seashells that lend beaches their charm could also provide information about how the brain converts memories and sensory information into action, according to research from the University of California at Berkeley and the University of Pittsburgh published online April 7 in the Proceedings of the National Academy of Sciences (PNAS).
CHAPEL HILL – Researchers at the University of North Carolina at Chapel Hill School of Medicine have identified a compound that could be modified to treat one of the most deadly types of cancer, and discovered how a particular gene mutation contributes to tumor growth.
The findings and potential treatment apply to a type of brain tumor called secondary glioblastoma multiforme (GBM). GBMs are part of a larger group of brain tumors called malignant gliomas, which is the type of cancer Senator Edward Kennedy suffers from.
CAMBRIDGE, Mass. -- In the classic waterfall illusion, if you stare at the downward motion of a waterfall for some period of time, stationary objects — such as rocks — appear to drift upward. MIT neuroscientists have found that this phenomenon, called motion aftereffect, occurs not only in our visual perception but also in our tactile perception, and that these senses actually influence one another. Put another way, how you feel the world can actually change how you see it — and vice versa.
