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.

We often hear about feelings that come from our gut. Researchers led by University of Arizona physiologist Maya Kaelberer are working to understand how our gut and brain communicate. Their studies could lead to new strategies for addressing diet-related diseases and more. Maya Kaelberer spoke to Leslie Tolbert, Ph. D Regent's professor emerita in Neuroscience at the University of Arizona.

The Trump administration is moving to dismantle some of the world's leading climate and weather research institutions. It's the latest result in the politicization of climate science. University of Arizona Environmental Science professor Kathy Jacobs explains how explaining climate science has turned increasingly difficult over the past several years. Kathy Jacobs spoke with Leslie Tolbert, Ph. D. Regent's professor in Neuroscience at the University of Arizona.

Scientists from around the world have spent two years examining material brought back to Earth from the asteroid Bennu by the University of Arizona-backed Osiris REx mission. U of A planetary scientist Jess Barnes discusses some of the findings from the Bennu samples, including how one of the minerals resembles ordinary kitchen table salt. Jess Barnes spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Many tribal communities are using sustainable practices associated with their culture, but water access is still an issue. University of Arizona environmental professor Karletta Chief discusses how tribes are adapting to drought conditions and ensuring there's enough water for farms and homes. Karletta Chief spoke with Leslie Tolbert, Ph.D Regent's professor in Neuroscience at the University of Arizona.

The rapid influence of artificial intelligence is making choice-making behavior more important than ever. University of Arizona marketing professor Martin Reimann discusses how potential consumers who can detect AI in advertising are less likely to choose those products over others. Martin Reimann spoke with Leslie Tolbert, Ph. D. Regent's professor emerita in Neuroscience at the University of Arizona.

Scientists are learning about the current drought in the Southwest by studying climate change in the past. University of Arizona researcher Ellie Broadman discusses drought evidence found in tree rings that show what happened in the jet stream before man-made global warming took place. Ellie Broadman spoke with Tim Swindle, professor emeritus in Planetary Science at the University of Arizona.

Generative artificial intelligence is emerging as a tool to look at how people learn language. University of Arizona professor Gondy Leroy discusses research into how advanced machine learning can help families diagnose autism through the way their children acquire speaking skills. Gondy Leroy spoke with Leslie Tolbert, Ph. D. Regent's professor in Neuroscience at the University of Arizona.
