    The importance of gut health
    Jan 9 2026
    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.

    People have spent decades trying to find a way to measure the dimension of imagination. University of Arizona neuroscientist Jessica Andrews-Hanna discusses what happens in our brains when we find ourselves lost in thought, or when we develop brand new ideas. Jessica Andrews-Hanna spoke with Leslie Tolbert, Ph.D. Regent's professor emerita in Neuroscience at the University of Arizona.

    Tracking drought patterns via the jet stream using tree rings
    Nov 10 2025
    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.
