The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Scientists identify several hundred genes that impact West Nile virus infection

Screening the entire human genome, a team headed by Yale University scientists have identified several hundred genes that impact West Nile virus infection. The findings reported Wednesday online in the journal Nature may give scientists valuable new clues about ways to intervene in a host of deadly viral infections.

Brain imaging study shows context and personality are both key in understanding our responses to emotional facial expressions

It is well appreciated that facial expressions play a major role in non-verbal social communication among humans and other primates, because faces provide rapid access to information about the identity as well as the internal states and intentions of others.

Diet which includes fish prevents dementia and stroke

New research says older adults could benefit from including tuna and other types of fish in their diet because it may help lower their risk of cognitive decline and stroke.

Oestrogen - a beneficial addition to treatment of schizophrenia in women

Australian scientists have found that women suffering from schizophrenia were less likely to suffer hallucinations or delusions, when the hormone oestrogen was added to their treatment.

High dose shot of vitamin C halts the spread of cancer

According to scientists in the U.S., a high dose of vitamin C given in the form of an injection may halt the spread of cancers.

Human brains pay a price for being big

Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution.

Genetic discovery may lead to new blood test for people at high risk for cancer

Research funded in part by the Canadian Cancer Society may lead to a genetic screening test that could help families who are at high risk for cancer.

Scientists discover link between DNA copy number changes and cancer risk

Scientists at The Hospital for Sick Children (SickKids) have discovered a link between a newly discovered form of inherited genetic alteration, termed DNA copy number variation (CNV), and cancer susceptibility.

Vitamin C injections slow tumor growth in mice

High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers, researchers from the National Institutes of Health (NIH) report in the August 5, 2008, issue of the Proceedings of the National Academy of Sciences.

Eating fish appears to lower risk of stroke in healthy seniors

Eating tuna and other types of fish may help lower the risk of cognitive decline and stroke in healthy older adults, according to a study published in the August 5, 2008, issue of Neurology, the medical journal of the American Academy of Neurology.

Anti-reflux surgery - research may lead to changes in treatment recommendations

Researchers at Wake Forest University Baptist Medical Center have found that the reflux and swallowing problems that are common symptoms in patients with Rett syndrome and other neurological impairments, may be caused by a different mechanism than they are in healthy individuals. The finding leaves researchers to wonder if these patients truly benefit from anti-reflux surgery commonly performed in these children.

Epilepsy drug gabapentin may reduce insomnia in recovering alcoholics

It's a Catch-22 of the highest order. People with alcohol problems often use alcohol to get to sleep -- but it actually keeps them from getting good-quality sleep all night long.

Immune system protein accurate predictor of survival in pediatric septic shock

About 4,000 children in the United States die every year from uncontrolled infections of the body known as septic shock, and researchers are pushing the boundaries of molecular science to find new therapies that can stem the condition. But a simple measure of an immune system protein within 24 hours of being admitted to the hospital for septic shock can predict survival in children, yielding a powerful tool for diagnostics and clinical trials of new septic shock therapies, according to a research team led by Cincinnati Children's Hospital Medical Center in the Aug. 1 American Journal of Respiratory and Critical Care Medicine.

Chronic exposure to estrogen impairs some cognitive functions

University of Illinois researchers report this week that chronic exposure to estradiol, the main estrogen in the body, diminishes some cognitive functions. Rats exposed to a steady dose of estradiol were impaired on tasks involving working memory and response inhibition, the researchers found.

Telemedicine could have a profound impact on the treatment of stroke patients throughout the world

Researchers at the University of California, San Diego Medical Center say that their first-of-its-kind study of a telemedicine program which transports stroke specialists via computer desktop or even laptop to the patient's bedside, using highly sophisticated video, audio and Internet technology, could have an immediate and profound impact on the treatment of stroke patients throughout the world.

Inherited form of hearing loss stems from gene mutation

Pat Phalin learned she had hearing loss at 30, when she volunteered to give hearing tests at her local school. The pupils heard sounds she could not hear.

Research team creates human ALS motor neurons

A team of researchers from the Harvard Stem Cell Institute (HSCI) and Columbia University, in a collaboration catalyzed by the Project A.L.S./Jenifer Estess Laboratory for Stem Cell Research, has demonstrated that pluripotent stem cells generated from a patient with ALS (amyotrophic lateral sclerosis) can be directed to differentiate into motor neurons - the very brain cells destroyed by ALS.

study shows compounds from soy affect brain and reproductive development

Two hormone-like compounds linked to the consumption of soy-based foods can cause irreversible changes in the structure of the brain, resulting in early-onset puberty and symptoms of advanced menopause in research animals, according to a new study by researchers at North Carolina State University. The study is a breakthrough in determining how these compounds can cause reproductive health problems, as well as in providing a key building block for how to treat these problems.

Scientists discover how a tiny protein senses all the communications in a cell

Cells rely on calcium as a universal means of communication. For example, a sudden rush of calcium can trigger nerve cells to convey thoughts in the brain or cause a heart cell to beat. A longstanding mystery has been how cells and molecules manage to appropriately sense and respond to the variety of calcium fluctuations within cells.
