Biology Stories

Explore the world of biology and meet some of our biologists. Here you can learn about the living world and find out what is so cool about biology that someone would do it for a living. Pick a story to read or listen to one of our podcast shows filled with guest scientists who share their experiences and passion for discovery.

This could bee - yes, bee - a key to our sweet tooth and possibly a way to learn more about diabetes.

Hacking is a word that is often tied to something bad. However, there are times when hacking can be for something good. Think of it as a tool that can be put to use for good or bad. We also think of hacking as something only done with computers, but can we hack other things? Dr. Biology has the opportunity to sit down with scientist Klaus Lackner to talk about how he is hacking the environment in order to pull carbon dioxide (CO2) out of the air. If he succeeds, it could help reduce CO2 in atmosphere and redirect it towards better uses.

Have you wondered if it was possible to be a cyborg? Half man and half machine? Scientists are conducting experiments to see how brains control robotic limbs.

While cannibalism is fairly common among insects and crustaceans, most backboned animals avoid feeding on their own kind.

McGaughey (pronounced McGoy) is a researcher at Arizona State University who studies reproduction of mammals. He is a consultant at a hospital, where he is part of a team that implants fertilized eggs into the uterus of women who have not been able to conceive a baby by other methods.

Even a toddler can recognize his mother's voice on the phone, but what parts of the brain help match voices and faces in your brain?

Not everyone has been on a hike and very few have hiked with a park ranger. Dr. Biology hikes South Mountain Park with not one but two park rangers. Park Rangers Liz Smith and Justin Olson are our guides for the 2.5 mile trip up Holbert Trail. This episode provides hiking tips and a preview of what treasures await those who hike this park.

Temperature is important to all organisms, including you. Professor Angilletta studies the thermal biology of animals, which means that he investigates how different temperatures affect them.

Every living thing must be able to reproduce and make offspring. Most of us are familiar with how humans and mammals make babies, but do all creatures reproduce in the same way? Do insects, like the beetle, give birth to little insects?

Searching for things on the Internet can be like hunting for a needle in a large haystack. Just how large is the Internet?

When was the last time you folded a piece of paper to make a fun shape? Maybe you made a paper plane or tried origami to make a swan. Believe it or not, the building blocks inside your body also need to fold into the right shapes to work properly. In this activity, you can build your own protein channel from paper.

When you think of the comic character the Hulk, you think BIG and that's what Dr. Biology does in this episode- he learns about a building-size instrument being used by a group of scientists. This monster instrument is called a synchrotron and is an important part of the XM2 microscope that is being built to look inside cells in a new way. Find out what biophysicist Gerry McDermott has to say about this powerful tool and also its link to the Hulk. Really there is a connection!

When you think of hummingbirds, you may think about how they can fly in almost any direction. But there is a lot more to these acrobatic birds than meets the eye.
