The book under review is about a sordid chapter in the history of medical invention. In the 1940s, US president Roosevelt launched an initiative to develop antibiotics to treat animals and humans, and to deal with the potential threat of biological warfare. Among the graduate students in the department was Albert Schatz, who was analysing soil samples to find an antibiotic that would cure tuberculosis.

HANDWASH brands like Lifebuoy and Dettol promise to make you 99 per cent germ-free. The promise rides on the properties of an antibacterial agent triclosan, which has been in use for over 40 years.

Next gen toilets

Issue Date: Sep 15, 2012
FOUND in the uninhabitable climes of Antarctica, psychrotrophic bacteria could be the answer to India’s sanitation problems. After successful experimentation in high altitude toilets used by defence personnel, the Defence Research and Development Organisation (DRDO) plans to use the bacteria to tackle the problem caused by open defecation in the country. It will also be put to use in Indian Railways.
