Their study will appear in the August 17 issue of Cell Metabolism. more

Gene's discovery could help prevent a leading cause of blindness in the elderly

University of Pittsburgh researchers have discovered a gene linked to age-related maculopathy (ARM), the leading cause of untreatable blindness in the elderly. Their discovery suggests a simple test might be able to identify those at risk for what is commonly known as macular degeneration (AMD) and may lead to the development of more effective preventive strategies. more

Scientists Find Cell Surface Enzyme Matriptase Causes Cancer  

Scientists at the National Institute of Dental and Craniofacial Research (NIDCR) and colleagues report in animal studies that a single, scissor-like enzyme called matriptase, when left to its own devices, can cause cancer. more

Methamphetamine abuse, HIV infection cause changes in brain structure  

New research published in the August 2005 issue of the American Journal of Psychiatry indicates that methamphetamine abuse and HIV infection cause significant alterations in the size of certain brain structures, and in both cases the changes may be associated with impaired cognitive functions, such as difficulties in learning new information, solving problems, maintaining attention and quickly processing information. Co-occurring methamphetamine abuse and HIV infection appears to result in greater impairment than each condition alone. more

Detecting smaller breast tumors contributed to longer survival trend
