PNAS Science Sessions Podcast

Summary: Science Sessions is the podcast program of Proceedings of the National Academy of Sciences (PNAS). Listen to brief conversations with cutting-edge researchers, National Academy of Sciences members, and policy makers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of research published in PNAS, plus a broad range of science news and discoveries that affect the world around us.


 Examining Proceedings | File Type: audio/mpeg | Duration: 5:00

PNAS is one of the world's most-cited multidisciplinary scientific journals and has been published by the National Academies since 1915. This podcast, part of the Sounds of Science produced by the National Academies, looks at the history and future of this publication with Ken Fulton, publisher of PNAS.

 Interview with Pamela J. Fraker | File Type: audio/mpeg | Duration: 4:49

Pamela J. Fraker was elected to the National Academy of Sciences in 2007. She is known for her investigations of the impact of nutritional deficiencies, particularly of zinc, on immune defense. Her work provided evidence that deficiency in protein--calories causes a decline in antibody and cell mediated responses, which leads to higher rates of infection, poor wound healing, and other adverse impacts in the malnourished and those with chronic disease.

 Interview with Ran Nathan | File Type: audio/mpeg | Duration: 4:43

Ran Nathan organized the Movement Ecology Special Feature for PNAS. He is an associate professor and the chair of the department of Evolution, Systematics, and Ecology at the Hebrew University of Jerusalem, in Jerusalem, Israel.

 Interview with Nina Fedoroff | File Type: audio/mpeg | Duration: 5:38

Elected to the National Academy of Sciences in 1990 for her work in the field of Plant Biology, Nina Fedoroff is a pioneer in the molecular aspects of plant transposable elements. Building upon the work of Barbara McClintock, she elucidated the sequence of some of these elements, demonstrated their utility for gene cloning and was instrumental in converting the study of plant transposable elements into one accessible by molecular techniques.

 Interview with Richard T. Durrett | File Type: audio/mpeg | Duration: 3:16

Richard T. Durrett was elected to the National Academy of Sciences in 2007 for his work in applied mathematical sciences. Durrett's research in probability theory concerns problems that arise from ecology and genetics. He has developed mathematical models to study the evolution of microsatellites, impacts of selective sweeps on genetic variation, genome rearrangement, gene duplication, and gene regulation.

 Interview with C. Owen Lovejoy | File Type: audio/mpeg | Duration: 5:03

C. Owen Lovejoy was elected to the National Academy of Sciences in 2007 for his work in the field of anthropology. Lovejoy overturned traditional models of human origins by integrating biomechanics into biological anthropology, demonstrating that the earliest hominids walked on two legs. He developed novel methods for quantifying sexual dimorphism and revealing the demographics of prehistoric humans.

 Interview with Albert Libchaber | File Type: audio/mpeg | Duration: 4:35

Albert Libchaber was elected to the National Academy of Sciences in 2007 for his work in physics. Libchaber has made lasting and fundamental contributions to experimental chaos dynamics and its application to biological physics, from elucidating the forces at work when a fish swims through water to defining the minimal conditions necessary for artificial life.

 Interview with John G. Hildebrand | File Type: audio/mpeg | Duration: 5:00

John G. Hildebrand was elected to the National Academy of Sciences in 2007 for his work in animal, nutritional, and applied microbial sciences. His work on the functional organization, physiology, and development of the central olfactory system of insects has made him a pioneer in analyzing neural mechanisms underlying chemosensory control of mating behavior and insect--plant interactions. This work has application in disruption of insect mating behavior and herbivory, with practical benefit to human health and welfare.
