Do scientists speak truth to power? During the Cold War, a group of American strategists and science advisors claimed to do precisely that. Styling themselves as figures of rationality and restraint, they insisted that mutual assured destruction was the natural logic of the atomic age: as long as nuclear deterrence was credible, no one would ever shoot first. This doctrine, known as "strategic stability," became the foundation of the arms control movement. But in this counterhistory, Benjamin Wilson shows that we have misunderstood them and their efforts.

Antibiotics are powerful drugs that can prevent and treat infections, but they are becoming less effective as a result of drug resistance. Resistance develops because the bacteria that antibiotics target can evolve ways to defend themselves against these drugs. When antibiotics fail, there is very little else to prevent an infection from spreading. Unnecessary use of antibiotics in both humans and animals accelerates the evolution of drug-resistant bacteria, with potentially catastrophic personal and global consequences.

In 1982, Professors Sagan and Turco made known their discovery of the concept "nuclear winter", a widespread cold and dark, resulting in agricultural collapse and world famine, that would be generated in even a "small" nuclear war. It was a landmark discovery that revealed in the starkest terms how vulnerable our civilization is to the long-term environmental effects of nuclear war.
