Researchers have been studying data from NASA's Juno spacecraft since the summer of 2016. University of Arizona planetary scientist Bill Hubbard looks back on nearly a decade of discovery from the orbit of Jupiter, our solar system's biggest planet. Bill Hubbard spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

A protein complex inside every living cell that tells it how to grow. Problems with the protein's signaling system can lead to neurological issues. University of Arizona biologist Andrew Capaldi describes how scientists are examining the inner workings of cells. Andrew Capaldi spoke with Leslie Tolbert, Ph D. Regent's professor emerita in Neuroscience at the University of Arizona.

Move over Biosphere 2, make room for Biosphere 3. Biosphere 2 director Joaquin Ruiz explains how artificial intelligence is moving the concept into the digital age, taking data and helping scientists develop new theories about the evolution of planet Earth. Joaquin Ruiz spoke with Tim Swindle, professor emeritus of planetary science at the University of Arizona.

Scientists are reassessing the potential for life on Trappist 1e, an Earth-type planet orbiting a star more than 40 light years from Earth. University of Arizona planetary scientist Sukrit Ranjan explains why the latest findings are casting doubt on an exoplanet that was once a top candidate for discovering extraterrestrial life. Sukrit Ranjan spoke with Tim Swindle, professor emeritus of planetary science at the University of Arizona.

Seven states in the Colorado River basin failed to meet a key deadline February 14 on a plan to conserve their shared water supplies. University of Arizona Hydrology and Atmospheric Sciences professor Laura Condon talks about the difficult choices ahead for water management in Arizona amid the ongoing drought. Laura Condon spoke with Leslie Tolbert, Ph. D. Regents Professor Emerita in Neuroscience at the University of Arizona.

Plasma scientists investigate ionized gases and how they interact with various materials. University of Arizona mathematics professor Lise-Marie Imbert-Gerard is studying how waves of energy travel through plasma. The findings could help scientists improve nuclear fusion technology.Lise-Marie Imbert-Gerard spoke with Leslie Tolbert, Ph. D Regents professor emerita in Neuroscience at the University of Arizona.

Fruit flies have been crucial for researchers developing the basic principles of biology and disease. University of Arizona neuroscientist Martha Bhattacharya describes how the insects became pivotal instruments in learning about human genetics. Martha Bhattacharya spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Many causes of death share the same common factor, the onset of advancing age. University of Arizona biologist George Sutphin describes how our understanding of aging could transform medicine in the future. He will be the first speaker in this year's College of Science free lecture series at Centennial Hall. George Sutphin spoke with Tim Swindle, professor emeritus in Planetary Science at the University of Arizona.

Sonoyta Pupfish are native to southern Arizona and listed as critically endangered. University of Arizona professor Peter Reinthal designed a project that brought the fish to Biosphere 2's Desert Biome habitat and give it a head start on survival. Peter Reinthal spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Los Angeles firefighters battled the Palisades Fire in January 2025. University of Arizona environmental health researcher Melissa Furlong talks about a study looking at the challenges the firefighters are now facing, including changes in blood proteins that can lead to cancer. Melissa Furlong spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.
