In 2009, Bruce left the FBI to become the Executive Director of the Institute of Applied Genomics at the University of North Texas Health Science Center. Bruce directs the Center for Human Identification and he is the Vice Chair of the Department of Microbiology, Immunology, and Genetics. He has published about 500 scientific articles and testified in over 250 criminal cases. Bruce and I discuss the missing children of Argentina's Dirty War, the O.J. Simpson trial, the 9/11 terror attack on the World Trade Center, the subsequent anthrax letter attacks and the advent of microbial forensics, the DNA Fingerprinting Wars, DNA genealogies and forensics, and making mistakes in forensics.

Episode 15. Bioterrorism: Paul Keim Feb 11, 2019

Show notes

Shortly after the al-Qaida terror attacks of September 11, 2001, a second wave of terror swept the United States – this time bioterrorism with anthrax mailed in letters as the weapon. Today my guest is Paul Keim, the scientist who conducted the genetic sleuthing and tracked down the source of the anthrax. Paul is the recipient of numerous scientific honors, and he is a professor of biological sciences at Northern Arizona University, where he directs the Pathogen and Microbiome Institute. In addition to the anthrax terror attacks, in today's episode we discuss the Soviet and Iraqi anthrax weapons programs, the Haitian cholera outbreak sourced to Nepalese peacekeepers, virulent avian influenza, Scottish heroin addicts, and the Japanese doomsday cult Aum Shinrikyo.

Episode 14. Aquaporins: Nobel Laureate Peter Agre Jan 11, 2019

Show notes

One of the greatest mysteries in biology, until 1991, was how water moves across cell membranes. Today's episode focuses on the history of the discovery of aquaporins, or proteins that act as water channels in cell membranes. My guest is Peter Agre, recipient of the 2003 Nobel Prize in Chemistry for his discovery of aquaporins. Among many other honors and leadership roles across his career, Peter became a member of the U.S. National Academy of Sciences in 2000 and served as President of the American Association for the Advancement of Science from 2009-2010. He is the Bloomberg Distinguished Professor in Molecular Microbiology and Immunology and in the School of Medicine at Johns Hopkins Bloomberg School of Public Health. Peter is also the Director of the Johns Hopkins Malaria Research Institute.

Episode 13. Water Sanitation: Dennis Warner Dec 11, 2018

Show notes

In 1854, in the Soho district of London, cholera swept through the population. The physician John Snow investigated the cause of the outbreak and hypothesized that it was due to contaminated water. So began the field of epidemiology. Today's episode focuses on water quality, sanitation and disease. My guest is Dennis Warner, who has worked for forty years in the field of water supply and sanitation, including for Catholic Relief Services, the Peace Corps, the University of Dar es Salaam, Duke University, the World Health Organization, the World Bank, and the United States Agency for International Development.

Episode 12. Climate Change: John Matthews Nov 11, 2018

Show notes

The effects of human induced climate change, predicted over a century ago, are already with us. My guest, John Matthews, is the coordinator at the Alliance for Global Water Adaptation, which is a network of water and climate professionals working towards solutions for sustainable water resources management on both technical and policy fronts. In today's episode, we look back at some of the history of climate change research and water resources management, and peer a little into the future of a changing world.

Episode 11. Winston Churchill's Science, Part 2: James Muller Oct 11, 2018

Show notes

Winston Churchill's outsized role and oratory in wartime, from the Great Boer War at the turn of the century to World War II, are well known. Beyond politics and battle, Churchill also displayed a keen interest in technological development and scientific advancement, the subject of today's podcast, which is part 2 of a two-part series. 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.

Episode 10. Winston Churchill's Science, Part 1: James Muller Sep 11, 2018

Show notes

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.

Episode 9. British Explorers, Part 2: Andrea Hart and Max Barclay Aug 11, 2018

Show notes

The Natural History Museum in London houses the greatest collection of natural history specimens in the world, collected for centuries by British explorers and scientists. In Part 2 of this episode on British explorers, my guests Andrea Hart and Max Barclay explain the role that these specimens and associated artwork played in the development of major scientific advances. Foremost among these specimens are the beetles, which held an outsized role in the history of evolutionary biology as well as in the childhood pursuits of collectors such as Charles Darwin and Alfred Russell Wallace. Andrea is the Head of Special Collections at the Natural History Museum, and Max is the Senior Curator in Charge of the beetle collection. So let's travel the world, from Africa to the Amazon to Australia and learn about the wonderful diversity of beetles, the eccentric people who collected them, and how their ideas changed the world. We'll do all this surrounded by annotated manuscripts, natural history drawings and specimens of the world's largest beetles within a Special Collections room of the Natural History Museum.

Episode 8. British Explorers, Part 1: Ian Owens Jul 11, 2018

Show notes

The Natural History Museum in London houses the greatest collection of natural history specimens in the world, collected for centuries by British explorers and scientists. From Captain Cook's discovery of Australia and Charles Darwin's voyage on the Beagle to the doomed Terra Nova Expedition to Antarctica led by Robert Scott, a steady stream of invaluable specimens has traversed the globe in order to be archived and studied. Taking us through this history is my guest, Ian Owens, the Director of Science at the museum. Ian is also a Professor at Imperial College London, and he specializes on research in the areas of biodiversity, ecology, genetics and evolution of birds.

Episode 7. Animal Intelligence: Irene Pepperberg Jun 11, 2018

Show notes

For over half a century, innovative scientists have tested the abilities of animals to learn to communicate using human systems, such as American Sign Language with chimps and gorillas. One could go back even farther in time, to the start of the 20th century, when the German mathematics teacher Wilhelm von Osten trained his Russian trotting horse Hans to answer questions, do simple math, and discriminate consonant vs. dissonant musical chords, all by nodding his head, tapping a hoof, pointing his nose, or picking up objects in his mouth. More recently, one of the most remarkable of such animal communication programs is that run by Irene Pepperberg. Irene has spent the past four decades teaching African grey parrots to talk – and not just to talk, but also to answer complex questions about the nature and number of objects. Irene's purpose is to test the limits of communication between humans and animals. Irene is the author of many articles and several books, including the New York Times best-seller "Alex & me. How a scientist and a parrot discovered a hidden world of animal intelligence – and formed a deep bond in the process".
