Ongoing research into the forever chemicals known as PFAS is putting an emphasis on the health risks firefighters face. University of Arizona public health professor Melissa Furlong discusses her studies regarding firefighters and their exposure to cancer-causing PFAS chemicals. Melissa Furlong spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Scientists are discovering more facts about how dogs age and what humans can learn from them. University of Arizona veterinary researcher Evan MacLean discusses the similarities between dogs and people when it comes to cognitive decline in their twilight years. Evan MacLean spoke to Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

A new study suggests we are facing a literal loss for words. University of Arizona psychology professor Mattias Mehl discusses the impact of people speaking hundreds of fewer words every day, and how devices like supermarket self-checkouts have eliminated ordinary chit-chat. Mattias Mehl spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

If you feel "butterflies in your stomach" during times of anxiety, it is likely your brain communicating with your gut. University of Arizona physiologist Maya Kaelberer discusses how the gut connects with the nervous system and impacts our behavior. Maya Kaelberer spoke with Erika Hamden, professor of Astrophysics at the University of Arizona.

The Lazuli Space Telescope is slated to be the first of its kind to be completely funded by private dollars. University of Arizona planetary scientist Ewan Douglas discusses the spacecraft designed to be larger than the Hubble Space Telescope, which was launched in 1990. Ewan Douglas spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

A small Earth orbiting observatory called SPARCS (SPARKS) is surveying solar activity that might impact life on faraway planets. University of Arizona planetary scientist Travis Barman describes how data from SPARCS can increase understanding about our own solar system.

The success of NASA's Artemis II mission is leading to discussion about a long-term human presence on the lunar surface. Former Paragon Space Development CEO Grant Anderson describes the challenges involved in creating a moon habitat for future explorers. Grant Anderson spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Biologists are reporting progress in unlocking the secrets of ALS, or Lou Gehrig's Disease. The University of Arizona's Russ Buchan and Kevin Rhine describe their collaborative efforts investigating the role genetics plays for patients coping with ALS. Russ Buchan and Kevin Rhine spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

COVID 19 became part of our lives as a global pandemic in March of 2020. Since then, scientists have tracked the phenomenon of Long COVID, where symptoms have lasted well after the patient has recovered. University of Arizona medical professor Sairam Parthasarathy discusses the ongoing research into Long COVID and why so many questions about the disorder remain unanswered. Sairam Parthasarathy spoke with Tim Swindle, professor emeritus in Planetary Science at the University of Arizona.

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.
