Every fall, the Leonid meteor shower puts on an amazing display with observers counting numbers from thousands to tens of thousands of meteors per hour. Joe Pesce, an astrophysicist with the U.S. National Science Foundation, discusses meteor showers, why they occur and how to view the Leonid meteor shower.

The future of science, technology, engineering and mathematics will require many perspectives to achieve its utmost potential. Keivan Stassun, professor of physics and astronomy at Vanderbilt University, discusses astronomy, his efforts in expanding diversity in STEM and some of the discoveries that are resulting from it at the Frist Center for Autism and Innovation, and his recent MacArthur Fellowship that acknowledges those efforts.

Advances in materials science and rapidly developing technologies are leading to new approaches to engineering concretes and building infrastructure. Reza Moini, assistant professor of civil and environmental engineering at Princeton University, discusses his work with concrete, 3D-printing techniques and how his lab takes inspiration from nature as it works to reimagine the future of building materials.

The world of artificial intelligence is changing the way people live, work and think. This new frontier is also shifting the world of scientific research and has led the U.S. National Science Foundation to launch the National Artificial Intelligence Research Resource pilot. Tess deBlanc-Knowles, NSF special assistant to the director for AI, discusses developing safe and responsible A.I. and how it is impacting new discoveries.

To advance the understanding of complex living systems, research must have an integration of scientific disciplines. Pankaj Jaiswal, a program officer in the U.S. National Science Foundation Division of Integrative Organismal Systems' Plant Genome Research Program, and Robyn Smyth, a program director in the NSF Division of Environmental Biology's Ecosystem Science Cluster, discuss plant genomes and water systems research.

An interagency effort has crafted a document to support the entire artificial intelligence research ecosystem, from foundational discoveries to societal applications. Jillian Mammino, a contractor at the U.S. Department of State's Bureau of Oceans and International Environmental and Scientific Affairs; Mary Beech, director of workers and technology policy in the U.S. Department of Labor’s Office of the Assistant Secretary for Policy; and Craig Jolley, a senior data scientist in the Bureau for Inclusive Growth, Partnerships, and Innovation at the U.S. Agency for International Development discuss the Global AI Research Agenda.

Plastics are foundational in modern life, but only a fraction of those produced are recycled. WashU researchers Arpita Bose, associate professor of biology; Eric Conners, a graduate student; and Tahina Ranaivoarisoa, a lab manager in the Bose Lab, discuss purple bacteria and how they might be used to produce biodegradable bioplastics.

An interagency effort has crafted a document to serve as a starting point to align an international artificial intelligence research vision. Michael Littman, the division director of the U.S. National Science Foundation Information and Intelligent Systems in the NSF Directorate for Computer and Information Science and Engineering, and Joshua E. Porterfield, a Federation of American Scientists Impact Fellow in the U.S. Department of Energy's Office of Critical and Emerging Technologies discuss the Global Artificial Intelligence Research Agenda.
