Nuclear fusion holds the promise of solving the world's energy challenges. University of Arizona researcher Tomas Diaz de la Rubia discusses the latest breakthroughs in developing nuclear fusion and how it has advantages over currently-operating nuclear power plants.Tomas Diaz de la Rubia spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Scientists have spent decades studying whale fossils found on land near the Chile's Pacific coast. University of Arizona Geosciences professor Barbara Carrapa discusses how volcanic activity in the Andes Mountains actually led to the demise of the whales seven million years ago. Barbara Carrapa spoke with Erika Hamden, professor of Astrophysics at the University of Arizona.

Evolution plays a role in why some species have more longevity than others. University of Arizona molecular scientist George Sutphin discusses how the process of aging produces what is naturally best for animals ranging from sharks to humans.George Sutphin spoke with Erika Hamden, astrophysicist at the University of Arizona.

A common antibiotic designed to help kids with breathing problems isn't performing as expected. University of Arizona pediatrics professor Fernando Martinez discusses why certain medications are not effective for treating asthma, and could lead to increased hospital stays instead. Fernando Martinez spoke to Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.

Some parts of southern Arizona have received higher-than-usual rainfall this summer. National Weather Service forecaster Julia Tetrault discusses what is making the monsoon more active than previous years, and why the conditions are just right for rain in southern Arizona. Julia Tetrault spoke with Erika Hamden, astrophysicist at the University of Arizona.

Scientists have discovered when one plant or animal faces extinction, the whole ecosystem is threatened. Michael Robinson with the Center for Biological Diversity talks about protecting the Mexican gray wolf in southern Arizona, and how it is crucial to wildlife patterns across the region. Michael Robinson spoke with Erika Hamden, Astrophysics professor at the University of Arizona.

Scientists have discovered certain plants get a head start on survival in drought conditions. University of Arizona researcher Alexander Bucksch discusses how some root systems use tiny hooks that bring in water and keep plants alive. Alexander Bucksch spoke with Erika Hamden, Astrophysics professor at the University of Arizona.

A new space telescope called PUFFINS will soon be viewing faraway stars through interstellar dust. University of Arizona astronomer Ramya Anche talks about solving the mysteries of polarization and stellar evolution using tools found only in outer space. Ramya Anche spoke with Erika Hamden, astrophysicist at the University of Arizona.

Warnings about hurricanes and tornadoes help save lives, but researchers are beginning to study how alerts about extremely hot and cold weather can make a difference, too. University of Arizona economics professor Derek Lemoine discusses the connection between better weather forecasts and mortality rates. Derek Lemoine spoke with University of Arizona astrophysics professor Erika Hamden.

Ongoing research into the forever chemicals known as PFAS is putting an emphasis on the health risks firefighters face.
