  • A Real Gas
    Just because something is invisible doesn’t mean it isn’t there. We can’t see gases in our atmosphere, such as carbon dioxide, oxygen, and nitrogen, but we benefit from their presence with every breath we take. From the bubbles that effervesce in soda to the vapors that turn engines, gases are part of our lives. They fill our lungs, give birth to stars, and… well, how would we spot a good diner without glowing neon? In this episode, a materials scientist shares the history of some gaseous substances that we don’t usually see, but that make up our world. Guest: Mark Miodownik – Professor of materials and society at the University College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.” Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network. Please contact [email protected] to inquire about advertising on Big Picture Science.

  • Going Multicellular
    Imagine life without animals, trees, and fungi. The world would look very different. But while the first life was surely single-celled, we don’t know just how it evolved to multicellular organisms. Two long-term experiments hope to find out, and one has been running for more than 35 years. Hear about the moment scientists watched evolution take off in the lab, and how directed evolution was used to create a multicellular organism. Also, how single embryonic cells become humans, and what all of this says about the possibility of life on other worlds. Guests: Jeff Barrick – molecular scientist at the University of Texas at Austin where his lab oversees the Long-Term Evolution Experiment that’s been running since 1988.  Will Ratcliff – an evolutionary biologist at Georgia Institute of Technology Ben Stanger – cancer researcher, professor of medicine and developmental biology at the University of Pennsylvania and author of “From One Cell: A Journey into Life’s Origins and the Future of Medicine.” Joseph L. Graves – evolutionary biologist and geneticist at North Carolina Agricultural and Technical State University and author of “A Voice in the Wilderness: A Pioneering Biologist Explains How Evolution Can Help Us Solve Our Biggest Problems.” Featuring music by Dewey Dellay and Jun Miyake Originally aired October 9, 2023 Big Picture Science is part of the Airwave Media podcast network. Please contact [email protected] to inquire about advertising on Big Picture Science.

  • Skeptic Check: Near Death Experiences
    Near death experiences can be profound and even life changing. People describe seeing bright lights, staring into the abyss, or meeting dead relatives. Many believe these experiences to be proof of an afterlife. But now, scientists are studying these strange events and gaining insights into the brain and consciousness itself. Will we uncover the scientific underpinning of these near-death events?  Guests: Steve Paulson - executive producer of To the Best of Our Knowledge for Wisconsin Public Radio Sebastian Junger - journalist, filmmaker and author of “The Perfect Storm: A True Story of Men Against the Sea”  Christoph Koch - neuroscientist at the Allen Institute in Seattle and chief scientist of the Tiny Blue Dot Foundation in Santa Monica California  Daniel Kondziella - neuroscientist in the Department of Clinical Medicine at the University of Copenhagen Featuring music by Dewey Dellay and Jun Miyake Originally aired September 25, 2023 Big Picture Science is part of the Airwave Media podcast network. Please contact [email protected] to inquire about advertising on Big Picture Science.

  • Spotlight on SETI ep 3: Pascal Lee
    How do we know where to look for life on other planets? SETI scientists use analog sites on Earth, not only to study how life has evolved here, but the geological conditions that made it possible. Devon Island in Canada is one such analog. It's been called Mars on Earth.  In this third episode, Gary Niederhoff talks with planetary scientist Pascal Lee, co-founder of The Mars Institute, and principal investigator of the Haughton-Mars Project at NASA Ames Research Center in Mountain View, California. They discuss how a remote arctic island offers clues about how liquid water once flowed on Mars, why the moons of the Red Planet are so mysterious, and Pascal’s discovery of a heretofore unrecognized Martian volcano in 2024.

  • Beyond the Periodic Table
    You interact with about two-thirds of the elements of the periodic table every day. Some, like carbon, oxygen, and nitrogen, make up our bodies and the air we breathe. Yet there is also a class of elements so unstable they can only be made in a lab. These superheavy elements are the purview of a small group stretching the boundaries of chemistry. Can they extend the periodic table beyond the 118 in it now? Find out scientists are using particle accelerators to create element 120 and why they’ve skipped over element 119. Plus, if an element exists for only a fraction of a second in the lab, can we still say that counts as existing? Guests: Mark Miodownik – professor of materials and society at the University of College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.” Kit Chapman – Science historian at Falmouth University, author of “Superheavy; Making and Breaking the Periodic Table.” Jennifer Pore – Research Scientist of Heavy Elements at Lawrence Berkeley National Laboratory.
