Science History Podcast

The possibility that world annihilation rests with the twitching fingertips of a dictator in North Korea and a narcissist in Washington motivated me to focus the second science history podcast on nuclear disarmament. As a bonus, we also discuss renewable energy, another fitting topic at a time when the United States stands alone as the only country in the world that is withdrawing from the Paris Agreement on Climate Change. My first guest is Jose Goldemberg, a physicist who has played a central role in the development of Brazilian science and policy for half a century. Jose's comments are put into the historical perspective of Cold War events by my second guest, Frank N. von Hippel, a professor and co-director of the Program on Science and Global Security at Princeton University and the Woodrow Wilson School of Public and International Affairs.

My guest Pete Myers has spent the past 30 years calling media attention to findings about toxic chemicals, while the industry producing those chemicals has worked to discredit the science and scientists involved. In the 1990s, Pete helped to establish the field within toxicology known as endocrine disruption. Since then, he has relentlessly brought the findings of this field into public view. It turns out that many chemicals are toxic because they disrupt the body's normal hormonal processes, hence the term endocrine disruption. Exposure to many of these chemicals in early development can cause diseases later in life. This includes diseases that people often associate with chemical exposure, such as cancer, as well as other problems such as diabetes, obesity, and infertility. The science of endocrine disruption, and its implications for humans and wildlife, matured into its own field of study in the 1990s, and Pete Myers was, and is, in the thick of it.
