NSF’s Discovery Files Podcast

Developing Semiconductors

Semiconductors are the backbone of modern electronics and energy-efficient ones will be critical for the future of artificial intelligence and quantum computing. Matthew Panthani, a professor of chemical and biological engineering from Iowa State University, discusses developing next-generation semiconductors.

Thorium Nuclear Clock

Time is used to set many standards by counting a periodic event with a known frequency. Eric Hudson, a professor in the department of physics and astronomy at UCLA, joins to discuss working to directly manipulate the energy level of an atomic nucleus using a laser, something that has never been done before and may result in the most accurate clocks ever.

Maui Fire Coastal Ecosystem Resilience

On August 8, 2023, a devastating fire swept through the town of Lahaina on the Hawaiian island of Maui. Andrea Kealoha, an assistant professor, and Sean Swift, a doctoral student, from the University of Hawaii at Mānoa, join to discuss their research into the impacts of wildfire on the coastal ecosystem.

Acoustic Fibers

From traffic to TVs and portable devices, people are surrounded by unwanted noise. Grace Yang, who worked on her doctoral degree as part of the fiber group at MIT, joins to discuss developing materials with acoustic properties for noise cancellation and sound suppression applications.

Imageomics

Most living creatures reveal themselves visually and are routinely photographed by humans from all walks of life. What if researchers could use those photos to answer fundamental biological questions? Tanya Berger-Wolf, a professor and computer scientist at The Ohio State University joins to share how she is using technology to extract information from images in the new field of imageomics.

Songbird Migration

Every year, songbirds across the United States make the arduous journey south to warmer winter climates and back again. But what behaviors, environmental cues, or genetic factors tell them it's time to go? Kira Delmore, assistant professor of biology at Texas A&M University, joins to share new insights into songbird migration.

Mysterious Return of Atlantic Surfclams

In the 1990s, Atlantic surf clams largely died off in their southernmost range off the coast of Virginia. Daphne Munroe, associate professor at the Rutgers University Haskin Shellfish Lab, joins to discuss Atlantic surf clams, rebounding fishing efforts, and how this species may be adapting to changing conditions.

Repurposing Carbon Dioxide

Greenhouse gases such as carbon dioxide act like an atmospheric blanket, but what if society could capture and repurpose those gases into useful products? Burcu Gurkan, professor of chemical and biomolecular engineering department at Case Western Reserve University, joins this episode to discuss electrochemical methods of carbon capture, how the resulting products might be used and how flow batteries may fuel the future.

Cicadas

This year billions of cicadas will emerge as the annual varieties are joined by the periodic Brood XIX and Brood XIII species that pop up every 13 and 17 years. Allen Moore, division director for the Division of Environmental Biology at the U.S. National Science Foundation, joins to discuss cicadas and answer some questions about these mysterious insects. 

Mayan Archeology

Prior to European arrival, the Maya peoples built a civilization in the inhospitable lowland jungles of Middle America. David Lentz, professor of biological sciences and executive director at the University of Cincinnati Center for Field Studies, joins to discuss his archeological findings from ancient Mayan cities.
