One of the newest trends in coffee shops is welcoming animals. The way these cafes work is that people pay to enter and get a free drink. People who don’t have time or room for a pet can come and spend time with animals, without having to own them. Most people come to pet the cats, rabbits, sheep, or owls in the cafe. But some cafes might be going too far. In South Korea, one cafe welcomes raccoons, a typically wild animal that can be dangerous. Listen to hear about a visit to this cafe and then debate: Should animals be allowed in cafes?

Animals with long limbs and lots of muscle should be faster than other animals. In reality, even though a giraffe has much longer legs than a cheetah, it runs only about half as fast. This is because there are other factors involved in acceleration and speed of animals, such as how much energy they have to burn. Listen to learn about how new research on animal speeds can give scientists clues about the lives of prehistoric animals.

The Tibetan Plateau is one of the highest and coldest places on Earth. Many of the world’s tallest mountains, including Mt. Everest, is on the Tibetan Plateau. For millions of years, animals living in this region have needed to adapt to extremely cold temperatures. When an ice age took over Europe and Asia about 2.5 million years ago, this adaptation may have given animals living on the plateau an evolutionary advantage. Listen to hear about the discovery of the woolly rhino on this plateau and the new theories resulting from the discovery.

A female baby mountain lion has been found in the Santa Monica Mountains National Recreation Area. Mountain lions in the recreation area are very isolated as the park is bordered by the Pacific Ocean, agricultural fields, and greater Los Angeles. Therefore, scientists believe that the baby mountain lion is likely a product of inbreeding among related lions with limited mating choices. This could lead to genetic defects and abnormalities in the mountain lions. Listen to learn more about the newborn mountain lion and the concerns about mountain lion inbreeding.

When dog owners talk to their pets, they usually use praising words and speak in an approving, cheerful tone. Neuroscientists studied the brains of dogs to learn more about how they interpret praise. By looking at certain pathways in the brain scans, the research team discovered some interesting results that suggest dogs may process the meaning of the words they hear in addition to the tone of voice. Listen to hear the details of the study about what dogs understand when we speak to them.

Woolly mammoths were large, elephant-like creatures that lived tens of thousands of years ago, during the last great ice age. The thick, furry coat is one of several traits that gave woolly mammoths an advantage in a very cold environment. Today, the closest biological relative is the Asian elephant, which prefers warmer climates. Scientists were curious about the genetic variations between the woolly mammoth and the Asian elephant, and what might account for the differences between the two species. In this audio story, we hear from a scientist who studied the DNA from the extinct mammoth and compared it to its contemporary descendant. Listen to learn more about what researchers discovered.

The Department of Fish and Wildlife wants to find out how bears will react to a new wind project. It will be the first commercial wind project on U.S. Forest Service land and will include 15 turbines.They started tracking bears by using radio collars to see how they move around before the turbines are in place. The collars had many problems, so they started using cameras to track the bears. Now they have data to study bears and wildlife both before and after the wind project begins. Share this story with your students so they can learn more about this wind project in Vermont and its impact on wildlife.

SeaWorld was known for its shows that feature killer whales doing tricks for an audience, but they’ve been phasing out these shows because of complaints from animal welfare groups. The critics have also wanted SeaWorld to end captive breeding of orcas, or killer whales. Recently the SeaWorld CEO announced it will end captive breeding of killer whales. It will expand other attractions, and increase rescue operations of marine mammals. Since orcas have a long life, they will introduce new, natural encounters with their orcas. Listen to hear more about the changes at SeaWorld.

Dogs have a powerful sense of smell. For a long time we’ve counted on their noses to help us find bombs. However, dogs have had some trouble detecting Improvised Explosive Devices (IEDs) in Iraq, Afghanistan and elsewhere. The Navy is currently funding research to improve their detection skills in this area. By exposing dogs to thousands of different scents, scientists are training dogs to recognize potentially explosive ingredients and mixtures. Listen to the story to hear more about this life-saving research.
