Secret of smallpox's success may lead to bioterror cure

...vaccinia generally only causes a mild infection in humans before the immune system responds and eliminates the virus, also leaving immunity to smallpox and other pox viruses in its wake. "And there has been anecdotal evidence that if you get exposed to smallpox and get vaccinated within 4 days of exposure,...

However, he said now that it is known where HCA has an effect in rats, the next step is to try and uncover its mechanism. He said that "if we can reduce the peaks and valleys of insulin with HCA, then ...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...berg. Because of the potential harm of mutations, humans and other mammals have evolved to make as few as possible. The machinery inside our cells has the ability to replicate our genomes extremely well, and the "polymerase" enzymes that replicate our DNA rarely make mistakes. Even when they do, we have mu...
