Scientists and researchers have taken a big step closer to a cure for the most common strain of avian influenza, or “bird flu,” the potential pandemic that has claimed more than 200 lives and infected nearly 400 people in 14 countries since it was identified in 2003.
Researchers at the U.S. Department of Energy’s (DOE) Argonne [...]
