Listen to the Ask A Biologist Podcast

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 90 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.!

Are plants made from thin air?

Have you ever wondered where plants get their mass? All those leaves and branches have to come from somewhere, but where?

Beetle dissection

If you had x-ray vision, where would you look first? Some of our biologists have looked inside of beetles to learn more about how they breathe and fly. Take a quick tour inside this x-ray view of the flower beetle Mecynorhina torquata.

Denaturing proteins

Every day, while you cook, clean, and eat, you break (or denature) proteins. Break some proteins on purpose this time, while learning about the importance of protein structure to life.

Imagine you want to pull a long cylinder-shaped piece of soil (called a core) out of the ground in your backyard. What kind of tools would you need? Find out how researchers collect cores in the Frozen Arctic.

Using gene editing to cut DNA

Gene editing seems to be in the news more and more, but how exactly does gene editing work? And what is CRISPR? Get an introduction to DNA, RNA, and CRISPR.

Dr. Biology drops in on biologist Michael Angelletta and the researchers in his labortory. Besides getting a fun tour of the place, he learns how they study animals and their methods of heating and cooling their bodies.
