Infectious Diseases Society of America strongly supports the STAAR Act

With extensively drug-resistant tuberculosis, life-threatening drug-resistant respiratory and skin infections, and other "bad bugs" routinely making headlines, infectious diseases physicians are applauding Rep. Jim Matheson (D-UT) and Rep. Michael Ferguson (R-NJ) for introducing H.R. 3697, the Strategies To Address Antimicrobial Resistance (STAAR) Act.

New Rensselaer tools speed stem cell research

Engineers at Rensselaer Polytechnic Institute have developed tools to help solve two of the main problems slowing the progress of stem cell research - how to quickly test stem cell response to different drugs or genes, and how to create a large supply of healthy, viable stem cells to study from only a few available cells.

Fetal neurons play role in adult brain

Subplate neurons - once thought to die after directing the wiring of the cerebral cortex or gray matter - remain in the white matter of the adult brain in small numbers and maintain activity, communicating with other neurons in the brain said researchers from Baylor College of Medicine and the University of Alabama at Birmingham in a report that appears in today's issue of the Journal of Neuroscience
