A Theory of Everyone with Michael Muthukrishna
Dr. Michael Muthukrishna, Associate Professor at LSE, joins Alan to explore his book, A Theory of Everyone. It reveals how cultural evolution—our “software” of beliefs, language, and logic—shaped humanity's unique trajectory. He explains the "laws" of energy and innovation: energy abundance fuels cooperation and progress, while innovations like the steam engine drive efficiency and competition. Michael highlights the "paradox of diversity," where fresh ideas thrive amid aligned communication and norms. He links societal challenges like division and inequality to resource scarcity and calls for leveraging technologies like AI and startup cities to foster collaboration, sustainable innovation, and global progress. Guest Bio Dr. Michael Muthukrishna is an Associate Professor of Psychological and Behavioral Science at the London School of Economics, with a unique academic foundation in software engineering and psychology from the University of Queensland, and advanced degrees from the University of British Columbia. He has held prestigious roles at Harvard, Yale, and the Canadian Institute for Advanced Research.

The Hidden Lives of Ants with Susanne Foitzik
Alan, an ant enthusiast since childhood, is joined by Susanne Foitzik, author of Empire of Ants: The Hidden Worlds and Extraordinary Lives of Earth’s Tiny Conquerors. She explains that while queens start colonies and lay eggs, they don’t control the colony. Worker ants take on specialized roles like brood care and foraging, with older ants handling riskier tasks. Ants communicate through pheromones and use impressive navigation skills. Some species, like the Argentine and fire ants, thrive in new environments due to human transport, forming super colonies. Susanne’s current research focuses on how ants regulate labor division and how parasites impact their behavior and longevity. Guest Bio Dr. Susanne Foitzik is a professor of evolutionary biology, Vice Dean of the biology faculty, and Acting Director of the Institute of Organismic and Molecular Evolutionary Biology at Johannes Gutenberg University in Mainz, Germany. She has held academic positions at Ludwig Maximilian University, the University of Regensburg, and as a postdoctoral fellow at Colorado State University. With a doctoral degree in biology and a habilitation in zoology, Susanne is widely published and the author of Empire of Ants: The Hidden Worlds and Extraordinary Lives of Earth’s Tiny Conquerors, a captivating exploration of ant behavior and ecology. Show Notes (2:12) How many species of ants there are (3:46) The role of ant queens and how they’re made (5:55) The different functions ants take on in the colony (9:01) How nests are created (11:02) How ants communicate and navigate (16:01) How certain ants have developed the ability to maintain livestock and how they do it (19:01) Ants’ more aggressive behaviors (22:34) What turns ants into “zombies” (25:34) The social immune system of ants (28:42) Invasive species of ants (32:39) Understanding ant-tink (34:31) What Susanne is working on now Links Referenced Empire of Ants: The Hidden Worlds and Extraordinary Lives of Earth’s Tiny Conquerors:

AMSE Science Report with guest Eric Jay Dolin
Following the horrific devastation wreaked by Hurricane Helene, I was so heartened to see many in our community and around the nation come together to help those who had lost everything. I had spoken a while back on our podcast, AMSEcast, with Eric Jay Dolin about his book, A Furious Sky: The 500 Year History of America’s Hurricanes. We talked about some of those storms, including the Galveston, Texas, Hurricane of 1900. The people there had been encouraged to think a hurricane could not do any serious damage to their island home due to a deeply flawed understanding of how those storms work. The results were horrendous. Eric and I also spoke about how modern technologies help us predict and track these monster storms.

Dr. Rita Colwell is a pioneering scientist and professor at the University of Maryland and Johns Hopkins who has made groundbreaking contributions to microbiology and public health. She joins AMSEcast to discuss her experiences being the first woman to lead the National Science Foundation as well as her advanced research on Vibrio bacteria and cholera while founding CosmosID to improve rapid pathogen detection. During the 2001 anthrax attacks, she led a cross-agency effort to identify the spores, revolutionizing DNA sequencing techniques. Overcoming sexism early in her career, Dr. Colwell's achievements are detailed in A Lab of One’s Own. Guest Bio Rita Colwell is a Distinguished University Professor with an appointment in the University of Maryland Institute for Advanced Computer Studies. Colwell is one of the world’s leading researchers of cholera—a waterborne disease estimated by the World Health Organization to strike three to five million people annually, many of them young children. Her efforts to track and predict cholera outbreaks are multi-faceted, combining bioinformatics with the pioneering use of satellite imaging.

Whether you like to have an occasional drink or are a teetotaler, you will enjoy a conversation I had on our podcast, AMSEcast, with Camper English about his book Doctors and Distillers: The Remarkable Medicinal History of Beer, Wine, Spirits, and Cocktails. Camper’s book is a fascinating look at how, over the centuries, many alcohols and various things we add today to cocktails originally had medicinal purposes. For example, monks in the Middle Ages were at the center of research on agriculture and the distillation of alcohol. One thing they produced for medicinal uses can be found today in many bars.

AMSE Science Report with guest Sam Kean Author of the Bastard Brigade
Ridge, Tennessee. Our home of Oak Ridge got its start as a major part of the monumental Manhattan Project, the nation’s successful effort to build the first atomic bomb and end World War II. We talk a lot at AMSE and the K-25 Atomic History Center about the history of the Project, the science and engineering behind it, and the role of Oak Ridge and other locations in its successful outcome. But what is hard to teach is the atmosphere that surrounded that work. Our nation was at war, our soldiers and marines, our sailors and airmen, fighting and dying on the battlefields of Europe and Africa, on the islands of the Pacific, on the vast oceans, in the skies. Every family in America was touched by this war, a war against powers of fascism and militarism, of genocide and oppression. And we were quite concerned that Nazi Germany was far ahead of us in the effort to build the atomic bomb. It became our focus to beat them in that race, and concurrently to do what we could to sabotage their efforts. I spoke on our podcast, AMSEcast, with award-winning author, Sam Kean, about his terrific book on this topic titled The Bastard Brigade: The True Story of the Renegade Scientists and Spies Who Sabotaged the Nazi Atomic Bomb. Here is Sam.

AMSE Science Report with Carl Zimmer
I have a fundamental question for you – what is life? For something seemingly so basic, it is quite hard to define. The Pulitzer Prize-winning author, Carl Zimmer, took on that topic in his book Life’s Edge: The Search for What It Means to Be Alive. I spoke with Carl on our podcast, AMSEcast, and, among other indicators of life, he raised one that was a bit surprising – life is defined, in part, by decision making, and not just for us creatures who have brains.
