Which animal holds the title of “man’s best friend”? Of course, the answer is the dog. Dogs have lived with humans for thousands of years. Scientists’ understanding of how this came to be has changed in recent years. Additionally, scientists now study dog DNA in the hope of learning more about human DNA. Listen to hear a scientist explain the current understanding of the bond between humans and dogs, and how man’s best friend is helping to uncover mysteries hidden in human DNA.
Just how fast is a cheetah? Fast enough to earn the title “fastest land animal on the planet!” In this audio story, a scientist explains how various adaptations allow the cheetah to run at unbeatable (and unbelievable) speeds. Listen to hear about external and internal adaptations that help the cheetah run so fast.
Most people don’t like to spend time thinking about snot, slime, and mucus. Believe it or not, these are important substances that keep humans and animals safe. In fact, there are scientists who study snot! Listen to hear one of these scientists talk about what snot is made of, which animals produce the most slime, and how humans and animals use snot and slime to stay safe and healthy.
Animals use their whiskers for more than just looking cute. This audio story features an interview with a scientist who studies how whiskers are used by different animals. Listen to hear how animals use whiskers to learn about the world around them and about an experiment that helps scientists learn how whiskers work.
The fastest animal on Earth is not a land animal. The peregrine falcon can fly at speeds of over 200 miles per hour when it hunts for its next meal. It is difficult to study something that moves so fast, so scientists have to use different methods to gather information. Listen to a scientist explain how physics and mathematical equations are used to answer questions about the flight of a peregrine falcon.
Paleontologists learn about dinosaurs by searching for and studying fossils, which provide evidence about how a living dinosaur would have looked or acted. They use what they learn to teach others. Occasionally, paleontologists make a discovery that changes a previously accepted idea. Listen to hear more about what paleontologists do, and to learn about some of the dinosaurs that have been discovered and named.
Human beings have a long-standing fascination with dinosaurs that dates back to the discovery of the first fossils. To this day, people of all ages visit museums and fossil sites to study and learn more about these prehistoric creatures. This audio story features the answer to a seemingly simple question: how did the dinosaur age begin? Listen to hear what scientists know about the beginning of the age of dinosaurs. The story may contain a few surprises!

Many scientists isolating at home during the pandemic have taken their study subjects with them. The researchers want to keep the plants and animals that they study alive and continue their experiments. Bringing spiders and even sunflower seeds home can have hazards, however. Listen to learn what scientists are doing to protect their study subjects during a health crisis and hear how one scientist’s roommates responded to the unusual critters in the house.

Dogs have powerful noses, and their sniffing skills might be able to help with keeping the pandemic under control. Many diseases have particular smells. Scientists are working to identify the scent of COVID-19 and training dogs to find it in humans. The trained animals would be able to quickly screen hundreds of people in places such as airports and train stations. Listen to hear how trainers teach dogs to find certain scents and when the first group of sniffers could be ready to work.

Snapping shrimp produce surprisingly loud noises by clicking their claws. The noises they make are so pronounced that they once led to a Navy investigation. Ocean warming is causing the snapping shrimp clicks to become even louder and more frequent. The increase in ocean noise from this and other human impacts can be disruptive to marine ecosystems where sound is important to survival. Listen to hear what snapping shrimp sound like and learn why their sounds might be helpful to some species and harmful to others.

The relationship between humans and dogs is a special one, and there are multiple theories about how it originated and how it has changed over time. All dogs evolved from wolves, and scientists are learning more about that evolutionary process through research about similarities and differences in the behavior of wolves and dogs. Listen to this story about a game of fetch and how it might inform scientists’ understanding of the history of the special relationship between species.
