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.

An interview with biologist Pierre Deviche and his passion for recording some of natures most interesting animals. Humans are not the only animals that have dialects as you will learn in this show. Dr Biology tests your skills again with a mystery animal quiz at the beginning of this show.

We used to believe that tadpoles always came from jelly-like eggs laid by frogs. However, scientists recently discovered that tadpoles don't always come straight from eggs.

A Common Kingsnake, Lampropeltis getula californiae, but this snake was anything but common. From the title of our story, you may have guessed that our snake, or maybe we should call it snakes, had two heads.

This animal lives in almost every part of the world and kills hundreds of thousands of people each year. What might surprise you is that you certainly have had a close encounter with the world’s most dangerous creature. Dr. Biology catches up with evolutionary biologist Silvie Huijben to talk about this killer animal that is the focus of her research as well as many other scientists around the world. Be sure to make your guess about the identity of the world’s most dangerous animal before you listen to this episode.

What motivates you? We hear this question a lot, and scientists decided it was time to find out. They tested which parts of the human brain are involved in creating feelings of motivation. 

Some ticks carry a nasty bacteria that they can pass on to humans when they bite. Learn how the health status of the humans they bite helps control what they pass.

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.

Every year billions of babies are dried and buried, not to be unburied for weeks, months, years or even decades. Don't worry, these are not babies like your little brother or sister, these are baby plants, or as you might call them, seeds. Why would a mom do such a thing?

An interview with biologist David Pearson, an author and expert on tiger beetles. Did you know that tiger beetles can run so fast that they go blind and just what would it be like to be hunted by these tiny, but ferocious animals? These are a few of the questions that we learn the answer from our guest biologist.

It's tiny versus the mighty and a battle for an acacia tree. Dr. Biology catches up with Beth Pringle a biologist exploring the savanna of Kenya. The two talk about two animals that seem mismatched for battle that has a surprise ending. Beth is also the biologist who took us along on one of her research trips to Kenya. You can go along too in our virtual savanna trip.

For many organisms, reproduction is a huge part of life. But what, exactly, does reproduction mean? Well, it can mean so many different things, including breeding or not, caring for young (or not), or giving birth (or not)... read on to learn about the diversity of ways that organisms reproduce.

Growing crops for a living can be a bit of a gamble. Do farmers who use genetically modified seeds have better results?

If you are a tobacco plant, you have a bad reputation. The link to cancer and other health related diseases is cause for any person to avoid you. But there is another side to this plant. Dr. Biology sits down with biologist Charlie Arntzen to talk about how tobacco plants are helping scientists produce treatments for viruses like Ebola.

Tobacco may have a bad reputation, but that is starting to change. Learn more about how Charles Arntzen is using this plant to treat the often-fatal disease Ebola.

Even with 'tiger' in their names, life is hard for these fast and often colorful insects. Also in: Deutsch | Español | Français | Português | Pусский | 日本語
