  • Invention and Exploration at the Smithsonian Institution

    Invention and Exploration at the Smithsonian Institution
    Oct 15 2025
    Host Alan Lowe continues AMSEcast’s exploration of 250 years of American innovation with Smithsonian experts Harold Wallace Jr., Dr. Eric Hintz, and Tim Pula. Together, they trace invention from Benjamin Franklin’s experiments to modern breakthroughs, highlighting the Smithsonian’s exhibitions, collections, and hands-on learning at Spark!Lab. The discussion spans collaboration with the Library of Congress, the role of failure in creativity, and how patents shape (but don’t define) innovation. The guests also reflect on nuclear technology’s history and social impact, and share how listeners can connect with the Lemelson Center and its nationwide Spark!Lab network inspiring inventors of all ages. Guest Bio Harold Wallace Jr., curator of the electricity collections, holds an MA and a PhD from the University of Maryland and specializes in the history of electric light and power. Dr. Eric Hintz, acting director of the Lemelson Center for the Study of Invention and Innovation, earned his MA and PhD from the University of Pennsylvania and curates exhibits on invention and creativity. Tim Pula, interpretive exhibits inventor for Spark!Lab, designs hands-on activities that inspire visitors of all ages to explore the process and spirit of invention. Show Highlights

  • Exploring the Human Microbiome with Dr. Bob Hettich

    Exploring the Human Microbiome with Dr. Bob Hettich
    Oct 1 2025
    Dr. Robert Hettich is a pioneer in bioanalytical mass spectrometry. In this episode of AMSEcast, he describes how microbiomes form, vary across the body, and influence digestion, immunity, and overall health. Dr. Hettich also explains metaproteomics, the study of microbial proteins, to reveal how microbes function beyond their genes as well as their applications from human health to environmental cleanup and bioenergy. Inspired by his daughter’s experience with Crohn’s, Robert Hettich is especially focused on microbiomes’ links to inflammatory and neurological diseases, including Parkinson’s and Alzheimer’s. Guest Bio Dr. Robert Hettich is a corporate fellow at Oak Ridge National Laboratory and leader of its Bioanalytical Mass Spectrometry Group in the Biosciences Division. He also serves as joint faculty in the Microbiology Department at the University of Tennessee. Earning his BS from the South Dakota School of Mines and Technology and a PhD in Analytical Chemistry from Purdue University, Dr. Hettich joined ORNL in 1986 and has since become a pioneer in microbiome and mass spectrometry research. Widely published and honored with multiple awards, he is recognized for advancing our understanding of complex microbial systems and their impact on health. Show Highlights
    • (1:45) What is a microbe?
    • (2:57) What is a microbiome?
    • (3:31) When microbiomes begin to develop in the body
    • (5:42) How microbiomes differ throughout the body
    • (7:51) The role of probiotics and prebiotics in microbiomes
    • (10:03) The effect of anti-microbial medication on microbiomes
    • (12:05) What metaproteomics is and what tools are required for it
    • (16:03) The role of microbiomes in development or materials, fuel, and other resources
    • (18:42) What Dr. Robert Hettich is most concerned about for his research
