chemical weapons

Scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide.

A light-transmitting compound that could one day be used in high-efficiency fiber optics and in sensors to detect biological and chemical weapons at long distance almost went undiscovered by scientists because its structure was too difficult to examine.

Scientists have developed a new method for rapidly and safely destroying toxic agents such as chemical weapons and pesticides.

When tested in solution, full destruction of all three tested agents was achieved in less than 30 seconds.

Testing on contaminated surfaces showed virtually complete decontamination of the agents in 10 minutes -- the shortest of the time periods tested.

Research by two Queen's scientists has resulted in an exciting new method for rapidly and safely destroying toxic agents such as chemical weapons and pesticides.
