For years, scientists have searched in vain for slivers of the brain that might drive the dramatic differences between male and female behavior. Now biologists at Harvard University say these efforts may have fallen flat because such differences may not arise in the brain at all.
Doctors can describe the symptoms of rosacea, a common inflammatory skin disease that causes facial redness and affects nearly 14 million Americans. They can tell patients what triggers can worsen their condition: spicy foods, heat, alcohol, even embarrassment. But until now, they could not explain what caused rosacea.
The discovery of a novel molecular switch that powerfully modulates nerve cell activity offers the potential for new mood disorder and epilepsy treatments, University of California, Irvine researchers report.
With the finding that fever is produced by the action of a hormone on a specific site in the brain, scientists have answered a key question as to how this adaptive function helps to protect the body during bacterial infection and other types of illness.
Artificially inducing menopause may reduce breast cancer recurrence in premenopausal women with early-stage breast cancers.
Even though you may think of whooping cough as one of those ailments from Grandma?s day, the truth is it?s still around and plaguing people of all ages.
Researchers predict as many as one in four people aged over 65 years will be diagnosed with dementia by 2020. To confront this looming health problem, a team of health care researchers led by the University of Western Sydney’s Professor Esther Chang, has been working on a series of related projects which aim to improve the lives of people with advanced dementia, their carers and families.
It’s the things a young child doesn’t do that may give the clues to the presence of Autism. Because early symptoms of Autism are often characterised by an absence of normal behavioural development rather than the presence of unusual behaviour, diagnosis and early intervention can be crucially delayed.
Two new large-scale genomic studies have honed in on the main genetic pathway associated with multiple sclerosis, while also uncovering new genetic variations in the disease and suggesting a possible link between multiple sclerosis and other autoimmune diseases.
One of six Autism Centers of Excellence (ACE) in the country has been established at the University of California, San Diego by the National Institutes of Health (NIH), to be directed by Eric Courchesne, Ph.D., professor of neurosciences at the UC San Diego School of Medicine and a leading expert on brain abnormalities associated with autism, a brain disorder affecting an estimated two million people in the U.S. The symptoms are impaired social, emotional, language and cognitive development.
