NSF’s Discovery Files Podcast

U.S. National Science Foundation-supported researchers are behind an educational effort to introduce artificial intelligence techniques to elementary school children. Educator Carrie Robledo discusses her project, "AI Insect Detectives," and experience as a 2026 Presidential AI Challenge national champion.

Tiffany Barnes, Shiyan Jiang and Xiaoyi Tian discuss their U.S. National Science Foundation-supported project "ElementaryAI," the challenges of introducing artificial intelligence concepts into elementary school curriculum and how the project led to a win in the inaugural Presidential AI Challenge.

NSF Noirlab's Robert Blum, director of operations for the NSF-DOE Vera C. Rubin Observatory, discusses the observatory's signature mission, the Legacy Survey of Space and Time, and how it will transform the way we study the universe.

As the 10-year Legacy Survey of Space and Time officially starts and the greatest cosmic movie ever made is captured, U.S. National Science Foundation Program Officer Edward Ajhar discusses the NSF-DOE Vera C. Rubin Observatory and how it will transform the way people study the universe.

An innovative new engineering approach may lead to denser, more powerful microchips and computing systems. U.S. National Science Foundation-supported researcher Qing Cao discusses a new monolithic, 3D-integrated silicon microchip and how it might impact artificial intelligence systems.

New, lifesaving treatments can be found at the intersection of bioengineering and medicine. U.S. National Science Foundation-supported professor Neil Forbes discusses how the bacteria salmonella can be modified for treatment against some of the deadliest cancers.

U.S. National Science Foundation-supported professor and director of the NSF Center for Complex Particle Systems Nicholas Kotov discusses complex materials and the development of new fused silk materials with applications in security and communications.

Hypertension affects nearly half of U.S. adults, and 10% of those cases don’t respond well to treatment. U.S. National Science Foundation-supported professor Tao Zhou discusses the development of a new 3D-printed hydrogel-based bioelectronic device for hypertension treatment.

Secure information is essential in the digital exchanges of modern life. U.S. National Science Foundation-supported professor Vinod Vaikuntanathan discusses quantum cryptography and the future of encryption.

Advancements in science and technology impact the well-being of the American people. U.S. National Science Foundation-supported professor Payam Heydari discusses a breakthrough brain-computer interface that controls a robotic exoskeleton, technology that could transform the lives of people living with spinal cord injuries.
