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.
Exploring space is exciting but are there drawbacks for astronaut immune function? Scientists are investigating how spaceflight affects immunity in fruit flies.
What happens when a person wants to have a baby, but after years of trying, it just doesn’t happen? A lot of people want to become pregnant, but let’s learn about what may prevent pregnancy.
As you go about your day, breathing and thinking, with your heart beating, your body is working. It sends and receives signals, grows, and stores fat, among hundreds of other functions. All of these functions make up your physiology, or how your body works. The same is true for every living animal.
What is a genetically modified organism (GMO)? How do you make something that is a GMO? Are they safe? These are just a few of the things Dr. Biology discusses with biologist Kevin Folta. The two also talk about how and where you can find information about science that you can trust to be the most accurate.
Birds in the city seem to have endless options of places to eat. How do they choose, and where do they prefer to eat most?
Scientists thought that flying reptiles known as Pterosaurs were slowly dying off before an asteroid caused a huge die-off on Earth. But new fossils found in Africa tell a different story.
Strange greenish lights can be seen at night in the forest. But who are these pre-planned signals for?
Most humans can determine whether or not they know someone by looking at her or his face. Scientists have discovered that humans are not the only animal with this ability. The cichlid fish can also use facial differences to tell each other apart.
Embark on a journey through the intricate dance of nature and innovation as we welcome Saad Bhamla, a scientist at the forefront of biological engineering. Your curiosity will be rewarded as you and Dr. Biology learn about some of the smallest organisms that have sophisticated mechanisms that might help us solve our own challenges. Imagine the immense power hidden within a cicada's waste jet or the swift knot-escaping antics of a California blackworm—some might think of them as quirks of evolution, but others see them as blueprints for the future of design and technology. Our conversation doesn't stop at scientific marvels; it delves into the heart of what drives this scientist's passion and has led to the creation of The Curious Zoo of Extraordinary Organisms.
When you think of the Arctic, you might picture mostly empty ice. But the Arctic ecosystem is home to many organisms, from microscopic bacteria to large animals like whales and polar bears. Much of this life in the Arctic depends on tiny organisms called plankton which make up the base of the food web.

There are more genders than just “man” or “woman” that a person can identify as. Let’s explore a variety of gender identities and learn about their history.
You might have heard of both gender and sex before, but what’s the difference? Sex is based in the biology of body parts, but gender is socially constructed and based on much more.
We are often taught that germs are bad, but what if exposure to germs or other microorganisms has long-term positive effects? Recent studies show that certain microbes in our environment might actually offer a protective effect against Alzheimer’s Disease.
Almost all life forms start out as small cells, but how do they grow into entire animals? Read about the first step here: when cells in an embryo form germ layers that give rise to every organ and tissue in the body.
Some people gaze out at the landscape and see plants. Associate Professor Kathleen Pigg of Arizona State University sees the latest chapter in a long story.
Is there such a thing as too much time on the Internet? Scientists are studying the affects of Internet use and how it can be addictive for some people.
This could bee - yes, bee - a key to our sweet tooth and possibly a way to learn more about diabetes.
Some organisms, like this fungus, are able to glow, as if they were from an alien planet. But until recently, plants couldn't glow. Learn how scientists have found a way to make plants glow here on Earth.
