Bioweapons Research Proliferates

BIOLOGICAL DEFENSE: Among the tools to counter effects from biological weapons, bioengineered red blood cells (above) can patrol the circulatory system, sponging up viral particles and carrying them to the liver for destruction. Synthetic macromolecules, or dendrimers (right), can capture viral particles and prevent further viral destruction of healthy cells. Biological weapons have been around since medieval warriors hurled plague-ridden corp

In October 1997, a United Nations special commission discovered evidence of bioweapons in Iraq; a month later, Iraq barred a U.S. team from inspecting suspect facilities, nearly precipitating war.

Authorities dropped the charges within days, however, when the FBI determined that the men had a vaccine strain, which they reportedly were stockpiling in case of attack by Iraq. And between the Iraq and Las Vegas incidents, President Bill Clinton announced last January in his State of the Union address his intent to strengthen the 1972 Biological Weapons Convention (BWC) "with a new international inspection system to detect and deter cheating."
