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.

Squirrels are notorious for being somewhat anti-social creatures. A team of researchers is trying to understand how the animals share crucial microbes that keep them healthy. University of Arizona evolutionary biologist Lauren Petrullo discusses the behavior of squirrels that leads to microbial exchange. Lauren Petrullo spoke with Tim Swindle, professor emeritus of Planetary Science 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.

Firefighters have found extensive underground burrows dug by prairie dogs helped them halt the advance of wildfires in some Western states. University of Arizona researcher Courtney Duchardt discusses data suggesting prairie dog colonies can alter landscapes and reduce wildfire spread and intensity. Courney Duchardt spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Tens of billions of pounds of wasted food ends up in landfills in the United States each year. University of Arizona professor Goggy Davidowitz is leading a team developing a system that collects food waste and dries it in a vertical greenhouse, so it can be used to fertilize fields and feed livestock. Goggy Davidowitz spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Researchers know dark matter exists in the universe, but the evidence is hard to find. University of Arizona astronomy professor Dennis Zaritsky explains how scientists are exploring the space between galaxies to resolve this decades-old mystery. Dennis Zaritsky spoke to Tim Swindle, professor emeritus of planetary science at the University of Arizona.
