Thomas Suddendorf

For thousands of years, scholars have struggled with what it means to be human. One critical dimension of humanity is foresight, and with us to decipher the evolution of foresight is Thomas Suddendorf. Thomas is a professor at the University of Queensland, where he investigates mental capacities in young children and in animals to answer fundamental questions about the nature and evolution of the human mind. Thomas is the author of over 140 research articles and two books: The Gap: The science of what separates us from other animals, published in 2013 by Basic Books, and The invention of tomorrow: a natural history of foresight (with co-authors Jonathan Redshaw and Adam Bulley), published in 2022, also by Basic Books.  Today we discuss archaeological finds related to stone tools, fire, hunting, ornaments, containers, burial, watercraft, maps, music, and storytelling - and what they tell us about the evolution of foresight.

Bethanie Carney Almroth

Johan Rockström and colleagues first proposed the concept in 2009 of planetary boundary threats and a safe operating space for humanity. This conceptual framework clarifies environmental problems that are of planetary significance, such as biodiversity loss, climate change, and stratospheric ozone depletion. The most recently articulated planetary boundary threat, or set of threats, relates to chemical pollution of the biosphere. With us to unpack planetary boundary threats as they relate to pollution is Bethanie Carney Almroth. Bethanie is a professor at the University of Gothenburg, where she researches threats posed to our planet due to the immense number and quantities of synthetic chemicals released into the environment.

James Muller

The 20th century was a time of unparalleled advancement in science and technology, along with the associated destruction caused by two world wars.  I think the most important person to positively influence the 20th century was Winston Churchill.  His importance was especially pronounced during World War II, in which his leadership may well have saved the world from long-term Nazi tyranny.  But Churchill played key roles in many realms of life, and especially in literature.  Indeed, Churchill was awarded the 1953 Nobel Prize for literature, which is certainly not the typical achievement of a politician.  Churchill also displayed a keen interest in technological development and scientific advancement, the subject of today’s podcast, which is part 1 of a two-part episode.  To explore Churchill’s connection to science and technology, I interviewed Jim Muller.  Jim is a Professor in the Department of Political Science at the University of Alaska Anchorage.  He is one of the world’s foremost authorities on Winston Churchill as well as the academic chairman of the Churchill Centre and the author of many works on Churchill.

Today we explore the history of plutonium with Frank von Hippel, a retired but always active professor at Princeton University, where, in 1975, he co-founded Princeton’s Program on Science and Global Security in the Woodrow Wilson School of Public and International Affairs. In the 1980s, Frank was the chairman of the Federation of American Scientists, and in the Clinton Administration he was the Assistant Director for National Security in the White House Office of Science and Technology Policy. Frank has worked on nuclear arms control and nonproliferation since the 1980s, and received many awards for this work, including a MacArthur Fellowship. Frank received his B.S. in physics at MIT in 1959 and his Ph.D. in theoretical physics at the University of Oxford in 1962, where he was a Rhodes Scholar. Frank is also a co-author of the forthcoming book, “Plutonium: How nuclear power’s dream fuel became a nightmare.” We discuss the history of all things nuclear – the development of the bomb, the attacks on Hiroshima and Nagasaki, plutonium bomb accidents during the Cold War, breeder reactors, radioactive waste, trans-uranic elements and neutron capture, nuclear terrorism and dirty bombs, nuclear testing, nuclear energy, and the people involved.

Noam Chomsky

Nothing is more human than language, and no one has done more to advance the science of linguistics than Noam Chomsky. Noam was born in 1928, and completed undergraduate and graduate degrees at the University of Pennsylvania just after the Second World War. He earned his PhD in 1955, and by 1957, he was already publishing landmark works in linguistics that disrupted the field and fundamentally altered the understanding of language. His work also devastated the field of behaviorism, led by the likes of B.F. Skinner. Noam is known as the father of modern linguistics, but his influence extends well beyond the study of language to include fundamental applications in computer science, philosophy, cognitive science, and many other fields. Noam has taught at MIT since 1955, and at the University of Arizona since 2017.

David Wake

Frogs have hopped around this planet for 200 million years. In comparison, anatomically modern humans have only been around for 200 thousand years. But the last half century has seen a tragic loss in amphibian biodiversity around the world. It seems especially striking that a group of animals that predate the dinosaurs have been devastated by modern human activities. With us today to discuss the history of discoveries in the area of amphibian declines is David Wake. David graduated from Pacific Lutheran College in 1958, and received M.S. and Ph.D. degrees from the University of Southern California in 1960 and 1964. He then taught at the University of Chicago before joining the faculty at the University of California, Berkeley in 1969. At Berkeley, David served as curator of herpetology and Director of the Museum of Vertebrate Zoology. He also served as President of the Society for the Study of Evolution, the American Society of Naturalists, and the American Society of Zoologists. In 1998, David was elected into the National Academy of Sciences.

Margaret McCarthy

The brain is the most enigmatic of organs – it is really a collection of organs that undergoes a remarkable coordinated development that is driven in part by sex steroids. Today my guest is Margaret McCarthy, one of the leading researchers on sex differences in the brain. Here, we cover the history of research on sex and the brain, including the utility of animal models, the roles of hormones and sensitive periods in brain development, masculinization vs. feminization of the brain, epigenetic regulation of sex differences in the brain, differences between the sexes in the prevalence and age of onset of mental illnesses, and even the role of politics in the field of neurobiology. Margaret received her BS and MA degrees in biology at the University of Missouri in 1981 and 1984, respectively, and her PhD in behavioral neuroscience at Rutgers University in 1989. She then worked at Rockefeller University and the National Institutes of Health before joining the faculty at the University of Maryland, where she holds an endowed professorship and is the Chair of the Department of Pharmacology.

Rai Weiss

We explore the history of the discovery of gravitational waves with Rai Weiss, including the relevance to special and general relativity, pulsars, supernovae, merging and binary black holes, space and time, neutron star collisions, dark matter, cosmic background radiation, gamma ray bursts, and even the viscosity of neutrinos. We also discuss really small numbers, the origin of the NSF and NASA, the LIGO scientific collaboration, the politics of science, and what all this has to do with Albert Einstein. Rai received his PhD at MIT in 1962, and taught at Tufts University and Princeton before returning to MIT. Among Rai’s many distinguished awards is the 2017 Nobel Prize in Physics, which he received along with Kip Thorne and Barry Barish “for decisive contributions to the LIGO detector and the observation of gravitational waves.”

Josh Shiode

Attacks on science and scientists have been a hallmark of the Trump administration, but such attacks emanating from the U.S. federal government are not new, nor are they restricted to one political party or one branch of government.  The best known of such attacks came from Bill Proxmire, who served in the Senate as a Democrat representing the state of Wisconsin from 1957-1989.  Proxmire achieved national recognition with his monthly Golden Fleece Awards, in which he mocked what he considered to be wasteful government spending.  After Proxmire retired from the Senate, other members of Congress took over the job of calling out what they saw as wasteful government spending on science in their own so-called wastebooks. My first guest is Melinda Baldwin, who comments on the history of the Golden Fleece Award and subsequent wastebooks.  My second guest is Josh Shiode, who comments on the history of an award designed to celebrate science - the Golden Goose Award.

Terry Collins

Chemistry has given the world the incredible diversity of fuels, pharmaceuticals, and household products that we rely on every day, along with tremendous advances in fighting infectious diseases and ensuring an abundant food supply. But the products of chemistry also include tens of thousands of toxic compounds that compromise human health, degrade the environment, and drive species to extinction. The advent of the modern environmental movement in the 1960s and 1970s produced a new field of chemistry dedicated to providing for the needs of society with less toxic and less environmentally damaging alternatives. This intellectual endeavor coalesced into the field of green chemistry. My guest, Terry Collins, is a leading green chemist and one of the founders of the field. His education includes a bachelor of science in 1974 and a PhD in 1978, both from the University of Auckland in New Zealand. He held a faculty position at the California Institute of Technology in the 1980s before joining the faculty at Carnegie Mellon University in 1988, where he is now the Director of the Institute for Green Science and the Teresa Heinz Professor of Green Chemistry. Terry is the recipient of numerous awards, including the Presidential Green Chemistry Challenge Award in 1998 and the Heinz Award for the Environment in 2010.

But the products of chemistry also include tens of thousands of toxic compounds that compromise human health, degrade the environment, and drive species to extinction. The advent of the modern environmental movement in the 1960s and 1970s produced a new field of chemistry dedicated to providing for the needs of society with less toxic and less environmentally damaging alternatives. This intellectual endeavor coalesced into the field of green chemistry. My guest, Terry Collins, is a leading green chemist and one of the founders of the field. His education includes a bachelor of science in 1974 and a PhD in 1978, both from the University of Auckland in New Zealand. He held a faculty position at the California Institute of Technology in the 1980s before joining the faculty at Carnegie Mellon University in 1988, where he is now the Director of the Institute for Green Science and the Teresa Heinz Professor of Green Chemistry. Terry is the recipient of numerous awards, including the Presidential Green Chemistry Challenge Award in 1998 and the Heinz Award for the Environment in 2010. He is also a Fellow of the American Chemical Society.

Ian Harrison

Freshwater ecosystems and their resident species have declined more rapidly than either terrestrial or marine systems and their species. Freshwater ecosystems face myriad stressors, from habitat loss and pollution to dams and climate change. Today I discuss the state of freshwater conservation science with Ian Harrison. Ian obtained his Ph.D. in systematic ichthyology at the University of Bristol in the UK. He has conducted research on marine and freshwater fishes in Europe, Central and South America, Africa, the Philippines, and the Central Pacific. He has worked for Conservation International and the IUCN’s Global Species Programme since 2008 and he is currently the freshwater specialist for Conservation International’s Moore Center for Science. Ian publishes extensively on the biology and conservation of fishes and the conservation of freshwater ecosystems.

Jason Wilder

Due to recent technological advances, scientists have revolutionized our understanding of human evolutionary history. What appeared to be a relatively simple story of divergence from ancient hominids is instead a tangled mess involving repeated cycles of divergence and hybridization between evolving human species. Today my guest is Jason Wilder, who researches human evolutionary genetics and genomics. We discuss the genetics of malaria resistance and parallel evolution, CCR5 deficiency and resistance to HIV infection, gene editing and the creation of designer babies, gene editing to treat disease, and introgression between modern humans and archaic forms, including Neanderthals and Denisovans. Jason received his B.A. in biology at Williams College and his Ph.D. in Ecology and Evolutionary Biology at Princeton University. He then worked at the University of Arizona and Williams before joining the faculty at Northern Arizona University, where he is a professor of genetics and the Interim Dean of the College of the Environment, Forestry and Natural Sciences.
