THERE is a story about an evening in late July 1969 when hundreds of monkeys on a coral atoll southwest of Hawai’i died. The US military killed them using ‘Utah’, hot particles dispersed by a bomb detonated in this area of the Pacific Ocean. Military scientists were pleased with the result of the test of a new biological weapon—a secret weapon that can spread and infiltrate, virtually invisibly, the tiniest body crevices.
