...t the University of California, San Francisco have deciphered a pattern of signals that spells life or death to each T cell of the immune system and may control the development of the body's natural defense arsenal. When a virus, parasite or other pathogen invades a cell, the immune system's T cells recognize...Researchers decipher fundamental signal for maleness
Researchers have deciphered the novel molecular structure of a protein that plays a critical role in determining male or female physical characteristics. Although the research was done in the fruit fly, Drosophila melanogaster, the researchers say the findings have implications...Scientists decipher structure of toxin responsible for botulism
