    Pluripotent Polymers

    Pluripotent Polymers

    Plastics have historically been developed to be optimal for a specific use, but what if a single material could be made flexible for one application or sturdy for another? We are joined by Stuart Rowan, professor of molecular engineering innovation and enterprise at the University of Chicago, who shares how he is developing materials whose properties can be changed on demand.       

    Crocodilia

    Crocodilia

    Crocodilian species first appeared during the Mesazoic era 252-66 million years ago and have since adapted to survive changing environments and mass extinction events. We are joined by Greg Erickson, professor of anatomy and vertebrate paleobiology at Florida State University and curator at FSU's Biological Science Museum, who shares how he measured crocodilian bite strength, what happens if a crocodile bites you, and how they inform the understanding of dinosaurs.

    Quantum Computing

    Quantum Computing

    Quantum information science is a rapidly advancing field. The unique possibilities that quantum phenomena offer will create breakthroughs in areas such as sensing and measurement, computation and simulation, communication, networking, and security. Dolev Bluvstein, a doctoral student at Harvard University, working in the Lukin Group at the Quantum Optics Laboratory joins to discuss how they are making strides in advancing quantum computing, the value of error correction and what the future may hold.      

    ZEUS and the Frontier of Laser Science

    ZEUS and the Frontier of Laser Science

    The U.S. National Science Foundation's Zettawatt-Equivalent Ultrashort pulse laser System (ZEUS) is the highest power laser system in the United States, providing world-leading capabilities for scientific, medical, defense and industrial research. We are joined by Karl Krushelnick, professor of nuclear engineering and radiological sciences and director of the Gérard Mourou Center for Ultrafast Optical Science at the University of Michigan, which houses ZEUS, to hear about how the laser works, the research that will be conducted there, and how extreme light interacts with different materials.

    Geographic Information Science

    Geographic Information Science

    From weather apps to maps, geographic information systems (GIS) are the computer-based tools that drive many modern-day conveniences. The U.S. National Science Foundation has played a central role in the technology's development and growth. NSF established the National Center for Geographic Information and Analysis (NCGIA) in 1988 and funded more than $83 million in grants in the last two years alone. We are joined by Jack Dangermond, who has served on advisory boards for NSF and NCGIA and alongside his wife Laura, who founded the Environmental Systems Research Institute, now known as ESRI, in 1969. Today, their proprietary software is among the most popular in the field. Dangermond discusses his role in the founding of NCGIA, how technology has transformed the field and the importance of conservation.  

    Macrophages and Cancer

    Macrophages and Cancer

    In the immune system, white blood cells help protect the body from viruses and bacteria. A subset known as macrophages offer great promise for cancer treatment. We are joined by Kolade Adebowale, a postdoctoral fellow at the Harvard John A. Paulson School of Engineering and Applied Sciences to hear about his macrophage studies, how they might be made more effective, and why we should be optimistic about the future of cancer treatment.

    Tyrannosaurids

    Tyrannosaurids

    Since the discovery of incomplete dinosaur skeletons in the early 1800s, the collective knowledge about these creatures that roamed the Earth millions of years ago has grown dramatically. We are joined by Greg Erickson, a professor of anatomy and vertebrate paleobiology at Florida State University and curator at FSU's Biological Science Museum who shares how new Gorgosaurus discoveries impact what we know about ancient eating patterns, how he aged the famous Tyrannosaurus rex Sue, and his role in uncovering a lost world of arctic creatures that is changing what we know about dinosaurs.      

    Lasers and Extreme Ultraviolet Light

    Lasers and Extreme Ultraviolet Light

    Light catches the imagination and raises questions about phenomena such as rainbows or why the sky is blue from an early age. We are joined by Franklin Dollar, professor of physics and astronomy and associate dean of graduate studies in the School of Physical Sciences at University of California, Irvine to hear about how he uses extreme ultraviolet light and lasers to reproduce and study the plasma states and particle acceleration that occur in the most extreme corners of the universe.  

    Advancing Computational Chemistry

    Advancing Computational Chemistry

    The U.S. National Science Foundation's Center for Computer Assisted Synthesis is developing data science tools and computational workflows that aim to shape the future of synthetic chemistry. We are joined by Gabe Gomes, assistant professor of chemistry and chemical engineering at Carnegie Mellon University, to hear about the work being done at the facility and the revolutionary new tool his team has developed, Coscientist.

    A Look Back at 2023

    A Look Back at 2023

    From the Viking age to a Cold War military installation revealing insights into the ice age, advances in artificial intelligence, and looks at black holes and gravitational waves in the depths of space, these are just some of the stunning findings produced by U.S. National Science Foundation-supported researchers in 2023. As we start a new year, we're looking back at some memorable moments from the past year's shows.

    Searching for Technosignatures

    Searching for Technosignatures

    Humans have always looked up to the sky and wondered about the stars and what life may be out there. Astronomers are using tools such as the U.S. National Science Foundation’s Green Bank Observatory and the Karl G. Jansky Very Large Array to search for radio waves, technosignatures sent from distant stars. David DeBoer, a research astronomer at the University of California, Berkeley joins to explain how Breakthrough Listen is leading this effort and how the Collaboration for Astronomy Signal Processing and Electronics Research is advancing the technology behind it.

    Listening To Giants

    Listening To Giants

    Blue whales are the largest animals to ever inhabit the planet and were hunted to near extinction in the era of commercial whaling. Since the 1960's, these giants have been protected but continue to be considered endangered and are seldom seen. Kate Stafford, an associate professor and bio-acoustician at Oregon State University's Marine Mammal Institute, joins today to explain how a film brought her to the Republic of Seychelles to locate blue whales using their vocalizations, share insights into whale song and explain how she hears climate change.

    Demonstrating Potential

    Demonstrating Potential

    The U.S. National Science Foundation's Graduate Research Fellowship Program (GRFP) has helped ensure the quality, vitality and diversity of the scientific and engineering workforce by recognizing and supporting outstanding graduate students since 1952.

    Microplastics in the Environment

    Microplastics in the Environment

    The ubiquity of plastic materials in modern life has meant that plastic debris can be found everywhere. A subset of these environmental contaminates, smaller than a sesame seed, are called microplastics, and an even smaller subset of those are called nanoplastics. We are joined by Lauren Pincus, an environmental chemist and post-doctoral fellow at Princeton University, to learn about plastic degradation, how it interacts with inorganic materials in the environment and what we might do to help prevent it.
