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.

Why Is Life the Way It Is?

What would life be like on other planets? This is just one of many questions that Biochemist and author Nick Lane talks about while visiting with Dr. Biology. Listen in as Nick explores not only life on our Earth, but also what it might be like on other planets. Nick also reads from his book, The Vital Question, and weighs in on the question of viruses - are they living or non-living?

Monster DNA

In the tiny world of DNA, we might call genomes monsters. These huge sets of information include all the codes for all the genes present in an organism. From genomes, we can learn about the traits, diseases, and evolution of a species, and that’s just a start. What might such a monster set of data do for us if it was about our very own North American monster – the Gila monster? Computational biologist Melissa Wilson Sayres tells Dr. Biology about the Gila monster, the life-saving venom in its saliva, and what we might learn from the monster genome.

Ocean Winds and Climate

Did you know the westerly winds in the Southern Ocean have been helping to keep our planet livable? Yes, they have been responsible for soaking up half of the human-made carbon dioxide (CO2) along with a whole lot of excess heat. Dr. Biology has the opportunity to talk with geoscientist Joellen Russell about the research she and a group of scientists have been doing in the southern hemisphere that tells us how important these winds and the oceans are for regulating the temperature of the planet.

Skeleton Secrets

Dead men tell no tales, but their bones can. It just takes a particular kind of scientist to read the clues that tell the story. Dr. Biology sits down with guest Tony Falsetti, a forensic anthropologist who knows his way around a skeleton. They talk about the role of forensic anthropology and some of the mysteries of history Tony has helped to solve.

Insect Infatuation

These fluttering icons of North America are a favorite of many people across the world, but they may be having some population problems. Don’t worry though, there are ways you can help. Conservation specialist Gail Morris talks with our student guest host Kayna Lantz about these colorful insects, their identification, migration, and the many groups that are working to better understand them.

One Wormy World

Around 4,000 years ago, on the wind-swept island of St. Kilda, Scotland, people started creating a food storage of sorts. They moved a population of sheep to the island, likely as a back-up food resource for when times were tough. Little did they know that their actions would affect 21st century science. Today, rather than ending up as a meal, sheep from this isolated population are the subjects of research on immune function. Ecologist Andrea Graham takes Dr. Biology on a trip of exploration through the dangerous cliffs, windy conditions, and wormy world that the Soay sheep deal with on St. Kilda.

Cybertaxonomy

The race is on. It is one where biologists and citizen scientists are working as quickly as possible to find and identify all the species on Earth before some go extinct. It might not seem like an important race, but we learn from entomologist Kelly Miller that not knowing what species we are losing might be more important than we think. To speed up the search scientists are using traditional and newer tools that are part of the world of cybertaxonomy.

Time Traveling Paleoentomologist

If you could travel back in time what would you find 50 million years ago? What was the climate like? Would you find the same plants? What animals were crawling, walking, and flying around? Paleoentomologist Bruce Archibald takes Dr. Biology back in time to explore the planet during the Eocene Epoch where things were a bit different than today – there was even a giant flying ant that would make anyone look twice.

Inner Space the Final Frontier

You hear that space is the final frontier, but could we have another frontier right here on Earth? The microscopic world offers a limitless opportunity to explore amazing places and life forms. You just need the right tool for the trip – a microscope. Guests Angela Goodacre and Doug Chandler have a conversation with Dr. Biology about the instruments that let us journey into inner space.

Rebooting the Immune System

Remember your last paper cut, or the bad cold that had you coughing and blowing your nose? It was your immune system that was busy trying to make you better by battling the bacteria or virus that was attacking your body. How your immune system works is the discussion Dr. Biology has with pediatrician Paul Turke. They also talk about how our immune systems have to reboot to keep up with evolving bacteria and viruses.
