[Bonus] From the Cutting Room Floor: Anthrax Decontamination Following the 2001 Attacks
In the inaugural “From the Cutting Room Floor” — where we take parts of interviews that didn’t quite fit in our regular episodes — we talk about anthrax. Well not exactly… we talk about what happens with the chemicals that we use to kill anthrax. In 2001, some high profile people like news anchors and senators received mail laced with anthrax — a spore-forming bacteria that can be deadly. Afterwar
Does Earth Have Limits?: The Chemistry of Pollution, Episode 4
Pollution is only one way humans are altering our planet. There’s climate change, sea level rise, biodiversity loss, and much more. Earth system scientists, including biological oceanographer Katherine Richardson, developed the nine planetary boundaries, a framework to understand what Earth systems are critical for life, and what will happen if human-caused changes to our planet continue. Katherin
The Soil and Superfund Sites Beneath Us: The Chemistry of Pollution, Episode 3
Water and air pollution may capture the headlines, but there’s another threat looming beneath our feet: soil. We farm on it, build cities on it, and pull water from it. But pollutants from industrial waste, mining, and trash settle in soil, wreaking havoc on existing ecosystems and threatening our food and water supply. Soil and environmental chemist Owen Duckworth shares how chemists study soil,
It’s a Watery World: The Chemistry of Pollution, Episode 2
We live in a watery world; 71% of Earth is covered in water. But humans have polluted Earth’s water for decades with pollutants like plastic, oil, and drugs. Marine chemist Chris Reddy guides us through what happens to the ocean during human-caused spills – from the Deepwater Horizon oil spill to the X-Press Pearl plastic spill – and how the ocean recovers. But our oceans aren’t the only waters at
The Air We (Want to) Breathe: The Chemistry of Pollution, Episode 1
In the first episode of our series on pollution, we’re turning to the very thing necessary for human life: air. Environmental engineer Pete DeCarlo introduces us first to the tools chemists use to study the air, including the early innovations by chemist Arnold Beckman. These tools alarmed us to the problem of air pollution and its impact on human health, from the smog derived from cars in Los Ang
Teaser: The Chemistry of Pollution
In this miniseries, Chain Reaction takes listeners on a sweeping journey through the hidden chemistry of pollution—above us, around us, and beneath our feet.The series begins with the air we breathe, tracing how chemists developed tools to detect invisible pollutants and how those discoveries revealed major public health crises, from urban smog and industrial emissions to the often‑overlooked dang

The Modern Chemist: The Origin Story of Chemistry, Episode 3
For centuries, chemistry in the United States was for one kind of a person: The white man. But now, after decades of progress, chemistry is more inclusive than ever.Historian Laura Puaca reveals how wars, feminist movements, and shifting societal expectations opened long‑closed doors for women in science. As feminism changed women's role in chemistry, other social movements were advancing the
The Chemists’ Wars: The Origin Story of Chemistry, Episode 2
Chemistry doesn’t just shape conflict — conflict shapes chemistry. And at no time in history is that more apparent than during the two world wars. Historian Alison McManus recounts how the race to weaponize toxic gases like chlorine and mustard gas transformed chemists into key military players, spurred industrial growth, and ignited an international arms race during WWI. However, some battles of
From Alchemy to Atoms: The Origin Story of Chemistry, Episode 1
In this debut episode of Chain Reaction, we go on a thrilling journey through the earliest chapters of chemistry’s history starting with the quest to make gold from abundant metals. Chemical historian Larry Principe guides us through the winding past of alchemy – its evolution across Greek, Islamic, and European traditions, and the secrecy, symbolism, and ambition that defined the craft.
