Scientists determine structure of staph, anthrax enzyme

Researchers at the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago have determined the crystal structure of sortase B, an enzyme found in the bacteria that cause staph and anthrax. While an antibiotic is probably five to seven years away, the structure could provide the first clue in developing a treatment for the infections.

Mitochondria in spinal cords is Lou Gehrig’s disease target according researchers

The selective killing of spinal cord neurons in amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, occurs when tiny cellular components called mitochondria actively recruit a mutant disease-causing protein into specific neuron cells, according to new research by University of California, San Diego (UCSD) School of Medicine investigators.
