A compound derived from green tea greatly diminished the neurotoxicity of proteins secreted by the human immunodeficiency virus, suggesting a new approach to the prevention and treatment of HIV-associated dementia, also known as AIDS dementia complex. The disorder is the most severe form of HIV-related neuropsychiatric impairment.

The first clinical trial to test a revolutionary treatment for blindness in children has been announced by researchers at UCL (University College London). The trial, funded by the Department of Health, is the first of its kind and could have a significant impact on future treatments for eye disease.

Aided by new observations from the Coupled Boundary Layer Air-Sea Transfer (CBLAST) hurricane field program, scientists at the Rosenstiel School of Marine and Atmospheric Science have helped to develop and test a new, high-resolution computer model to better understand how air-sea interactions directly affect hurricane intensity, a factor not yet possible in the current operational forecast models.

Elderly men and women who consumed higher levels of calcium and vitamin D are significantly more likely to have greater volumes of brain lesions, regions of damage that can increase risk of cognitive impairment, dementia, depression and stroke.

Duke University scientist Dr. Martha Payne reported this finding at Experimental Biology 2007, in Washington, DC.

Researchers have found a chemotherapy treatment that targets specific cells, reducing discomfort.

A new class of compounds developed by two University of Kentucky researchers shows promise as a nontoxic treatment of some cancers previously treated with toxic chemotherapy, the researchers report today.

In order to comprehend the continuous stream of cacophonies and visual stimulation that battle for our attention, humans will breakdown activities into smaller, more digestible chunks, a phenomenon that psychologists describe as "event structure perception."

Event structure perception was originally believed to be confined to our visual system, but new research published in the May issue of Psychological Science, a journal of the Association for Psychological Science, reports that a similar process occurs when reading about everyday events as well.
