Biology Podcast and Videos

You have been reading about the biologists behind the Ask A Biologist website. Now you can listen to them in our popular biology podcast show. Dr. Biology has been speaking with many of the biologists that are discovering new worlds and exploring new frontiers in biology. There are over 80 episodes and we continue to add more interviews. Each show includes a full written transcript and content log.

Want to watch some of our biologists in action? We are also building a collection of biologists in the lab and the field. Pick the "Watch" tab and pick one of the shows featuring our biologists.

When Good Cells Go Bad

What happens when good cells go bad? In this program Dr. Biology talks with cell biologist Michael Berens about cells and why they sometimes go bad. Could it be the genes and if it is a genetic breakdown could the new world of translational genomics hold the key to new treatments?

Fire and Life

Could fire be important for life on Earth? Would Earth be the same without fire? These are just a few of the many questions we have for fire researcher Stephen Pyne about fire and its role with life. Did we also mention his battle with a dragon? If you have a burning desire to learn the answers to these questions, tune in.

Watching Grass Grow

Travel to Northern Arizona to the research site of ecologist Stan Feath and learn what he has learned from two native grasses. Who would have thought so much could be learned from these simple plants and the microscopic ecosystem that is part of their success. We also learn how Sleepy Grass got its nickname and the secret of why a fungus found in grasses could end up helping humans.

Roses are Red and Violets are Blue, but Why?

What is color? Do all animals see color? Do all animals see the same colors? In this show we learn the answer to these questions and about the colorful research that ecologist Kevin McGraw has been doing with birds and their colorful feathers. We even learn how the color "red" plays a special role for many animals including humans.

Bugs in Films

Microbes are everywhere, but what are they? We get the inside story from microbiologist Valerie Stout about these tiny life forms including a slimy and gooey material many microbes make called biofilms. In fact, you have a daily encounter with biofilms and bacteria that can impact your health.

Stressed Out

What is stress? We often know what stress feels like, but what is it and what causes it? We get a chance to learn about stress, the brain, and two very important areas in the brain, the hippocampus and hypothalamus. We also learn how the very vocal Bull Frog is helping biologist Miles Orchinik learn about stress and the brain. Listen to a ribbiting show...
