Arizona Science

An organization that helps researchers win grants for their work on the University of Arizona campus nearly shut down because of the Trump administration's funding freeze earlier this year. BRISA Center for the Environment director Paloma Beamer discusses how it is continuing its mission despite losing support from the federal government. Paloma Beamer spoke with Leslie Tolbert, Ph. D Regent's professor emerita in Neuroscience at the University of Arizona.

It's been almost 20 years since Pluto lost its status as the ninth planet in our solar system. Now astronomers think they have identified a candidate to take its place. Katherine Volk with the Tucson-based Planetary Science Institute discusses a rare object that is orbiting the sun in step with the eighth planet, Neptune. In this extended episode, Katherine Volk spoke with Tim Swindle, professor emeritus in Planetary Science at the University of Arizona.

Astronomers released the first photographs from the Vera Rubin Observatory two months ago. Operations director Robert Blum describes how the University of Arizona-backed instrument is creating anticipation among scientists for new discoveries about the universe.

Dryland farming has been a staple for indigenous desert communities for centuries. University of Arizona professor Michael Kotutwa Johnson discusses how modern solutions to growing crops during the drought can be developed through traditional farming methods practiced on tribal lands. Michael Kotutwa Johnson spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Some of the earliest known evidence of humans living in and around southern Arizona and New Mexico has been traced to around 23,000 years ago. University of Arizona archeologist Vance Holliday discusses his finds near White Sands Missile Range and how they add to the book of human history in the region. Vance Holliday spoke with Leslie Tolbert, Ph.D. regent's professor emerita in Neuroscience at the University of Arizona.

Asteroid trackers are scanning the Earth's neighborhood to find any objects that pose a threat to our planet. University of Arizona planetary scientist Vishnu Reddy discusses a network designed to coordinate efforts worldwide to respond to potential life-threatening asteroid impacts. Vishnu Reddy spoke with Tim Swindle, professor emeritus in Planetary Science at the University of Arizona.

Researchers have found stress and trauma experienced during childhood leads to emotional and cognitive disorders later in life. University of Arizona behavioral neuroscientist Lindsay Halliday discusses how brain development is affected by our early environment. Lindsay Halliday spoke with Leslie Tolbert Ph. D. Regent's professor emerita in Neuroscience at the University of Arizona.

The Sonoran Desert region called Pinacate is often compared to other worlds in our Solar System. David Crown with the Tucson-based Planetary Science Institute explains how researchers are comparing Pinacate's ancient lava flows to photographs taken of Mars by robotic explorers. David Crown spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.
