When science goes backward  NOV 18 2010

John Horgan argues that in some areas, science and technology are moving in the wrong direction. Among those areas are space colonization, the origin of life, and ending infectious disease.

Decades ago antibiotics, vaccines, pesticides, water chlorination and other public health measures were vanquishing diseases such as malaria, yellow fever, polio, whooping cough, tuberculosis and smallpox, particularly in First World nations. In The Coming Plague: Newly Emerging Diseases in a World out of Balance (Penguin, 1995), the journalist Laurie Garrett noted that in 1967 U.S. Surgeon General William Stewart said that it was "time to close the books on infectious diseases" (Garrett's words) and shift resources toward non-infectious killers such as cancer and heart disease. The global eradication of smallpox in 1979 seemed to fulfill Stewart's vision. Hopes for the end of infectious disease were soon crushed, however, by the emergence of AIDS, mutant flu viruses and antibiotic-resistant forms of old killers such as tuberculosis.
