New imaging method shows early in treatment if brain cancer therapy is effective
A special type of MRI scan that measures the movement of water molecules through the brain can help doctors determine halfway through treatment whether it will successfully shrink the tumor or a patient's cancer will continue to grow. view more (2005-11-01)
'Speed of thought' guides brain's memory consolidation
Scientists at The University of Arizona have added another piece of the puzzle of how the brain processes memory. view more (2007-11-16)
Bigger brain size matters for intellectual ability
Brain size matters for intellectual ability and bigger is better, McMaster University researchers have found. view more (2005-12-23)
Virginia Tech researcher examining malignant melanoma in horses
Malignant melanoma is a dangerous, aggressive form of cancer and approximately 54,000 new cases are diagnosed every year, according to the American Cancer Society. view more (2006-02-01)
Brain changes significantly after age 18, says Dartmouth research
Two Dartmouth researchers are one step closer to defining exactly when human maturity sets in. In a study aimed at identifying how and when a person's brain reaches adulthood, the scientists have learned that, anatomically, significant changes in brain structure continue after age 18. view more (2006-02-07)
Immune response to HIV in the brain
Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus. view more (2006-04-28)
Engineered stem cells show promise for sneaking drugs into the brain
One of the great challenges for treating Parkinson's diseases and other neurodegenerative disorders is getting medicine to the right place in the brain. view more (2005-12-15)
Omega-6 fats cause prostate tumors to grow twice as fast
Omega-6 fatty acids-such as those found in corn oil-caused human prostate tumors in cell culture to grow twice as quickly as tumors to which omega-6 fats had not been added, according to a study conducted at the San Francisco VA Medical Center. view more (2006-02-01)
Mind over matter: SH2B1 in the brain regulates obesity
Obesity is one of the main risk factors for developing type II diabetes. Previous studies have shown that mice lacking a protein known as SH2B1 throughout their body are obese and develop diabetes. view more (2007-01-19)
Clinical trials with immunotherapy for breast and colorectal cancer
Researchers at Mount Sinai School of Medicine are conducting clinical trials on a unique approach to enhance the immune system in patients with breast or colorectal cancer. view more (2005-11-01)
New evidence supports century-old theory of cancer spread
A Yale School of Medicine study in the December issue of Lancet Oncology challenges mainstream oncology researchers to consider tumor cell hybridization with white blood cells as a major reason that cancer metastasizes or spreads to other parts of the body. view more (2005-12-13)
Study finds novel vaccine curbs brain tumor growth, increases survival
A novel vaccine has significantly increased life expectancy in patients with glioblastoma multiforme (GBM), the most dangerous type of brain tumor. view more (2006-04-26)
Good news for the medical marijuana movement: pot proliferates brain cells and boosts mood
Most drugs of abuse decrease the generation of new neurons in the brain, but the effects of marijuana on this process, called neurogenesis, had not been clear. view more (2005-10-14)
Penn researchers study the use of ultrasound for treatment of cancer
For the first time, ultrasound is being used in animal models - to treat cancer by disrupting tumor blood vessels. view more (2005-11-07)
Adaptation to oxygen deprivation elucidates tumor physiology
Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand. view more (2006-03-08)
Subtypes of ependymomas arise from rare stem cells in the nervous system
Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs). view more (2005-10-18)
Asleep or awake we retain memory
Sleeping helps to reinforce what we've learned. And brain scans have revealed that cerebral activity associated with learning new information is replayed during sleep. view more (2006-03-28)
Researchers break chain of biochemical events that brain cancer cells use to evade therapy
In their quest to find and exploit vulnerabilities in the natural armor that protects malignant brain tumors from destruction, researchers have found a way to decrease the cells resistance to therapies that are designed to trigger cell death. view more (2006-02-06)
A coffee with your doughnut could protect against Alzheimer's disease
A daily dose of caffeine blocks the disruptive effects of high cholesterol that scientists have linked to Alzheimer's disease. A study in the open access publication, Journal of Neuroinflammation revealed that caffeine equivalent to just one cup of coffee a day could protect the blood-brain barrier (BBB) from damage that occurred with a high-fat... view more...

Blood flow in brain takes a twist, affecting views of Alzheimer's
New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease. view more (2006-01-06)
