Scientists are curious about how humans evolved to help each other, which is different from the typical behavior of other animals. To investigate social behaviors such as helping and sharing, researchers have performed experiments to see how willing other primates are to share food and supplies. Listen to learn about their research on how other primates approach sharing and how that differs from human behavior.

Traffic, usually considered an urban problem, has been an issue at Yosemite National Park for a long time. While the park is sometimes shut down to all traffic because of forest fires, when it reopens, hundreds of cars come back to enjoy the majestic natural beauty of the park. Figuring out a solution to this problem has become even more important recently with an increase in bear deaths in the park. Listen to hear about how traffic jams in this popular national park are affecting the wildlife there as well as visitors’ experiences.

In Spain, Catholics remember the patron saint of animals, San Anton, with a festival that celebrates pets. Dogs, cats, birds, and sheep are walked down the streets in the arms of their owners. The pet owners travel to church so that their pets can be blessed. Many have looked to San Anton to help with their animals, and many believe it is important to have a day celebrating this saint. Listen to learn about the variety of animals involved and how they react to the pet blessing.

You can tell a lot from a tiger’s roar. A researcher in Texas is using the sound of tigers’ vocalizations to track and protect them in national parks and in the wild around the world. By monitoring tigers acoustically, researchers can track their location and know whether a tiger is a male or female, its weight, and other characteristics. Listen to learn why this project is helping tigers in captivity and in the wild.

An experienced marine biologist who has worked with whales for many years, was terrified when a humpback whale took her under its fin. Suddenly, she was being rolled around by the whale and forced to hold onto its head. But the scientist then realized there was a very good reason for this strange behavior. Listen to learn how her story made front page news and what happened to her a few days after the story broke.
Cats are mysterious creatures to us humans for many reasons. One of these reasons is that cats seem to always land on their feet whenever they fall. In fact, cats can be dropped upside down and still land on their feet, every time. But, how do they do this? It seems to defy the laws of physics. The answer has to do with momentum, and is explained by an expert. Listen to hear about how cats achieve this amazing feat.

A turkey at the Poplar Spring Animal Sanctuary in Maryland is not worried about becoming Thanksgiving dinner. Instead this turkey will be the guest of honor at dinner. Every year hundreds of people who eat only vegan or vegetarian food gather to eat with the turkeys, pigs, sheep, and other farm animals at Thanksgiving time. And they let the animals eat first. With help from charitable donations, this sanctuary has over 200 animals and a full-time caretaker. Listen to hear more about this unusual feast at Thanksgiving.

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.

One animal shelter is using social media to lead to raise animal adoption rates. Over the course of the last five years, a government-run shelter in Virginia went from euthanizing one-third of all stray animals to a nearly 90% adoption rate. By reaching out to the public for help on social media, the Animal Care and Control department has been able to find more animals homes more quickly. Listen to learn more about this department's innovations and then debate solutions in class on how social media can help save more abandoned dogs and cats.

The U.S. Capitol is a very dog-friendly workplace and lawmakers have been bringing their dogs to the Capitol since the 1800s. They used to sit at Congressmen’s feet in the Senate Chamber and roam the hallways with their owners. There are occasions when the dogs fight with each other, but mostly they are a friendly face in the lawmakers’ workplace. Listen to hear more about these dogs and their long history in the Capitol.

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.

Sharks can live to be over two hundred years old, and recently a Greenland shark was found who may have lived up to 512 years. These sharks are the longest living vertebrates known to exist. They can be found swimming in the Arctic seas, where researchers are spending time studying the old creatures. Listen to the story to hear more about this fascinating species.
Current Event September 15, 2016
Dolly the sheep became famous two decades ago for being the first mammal to be successfully cloned. Today, four sheep that came from the same cells as Dolly have reached their ninth birthday. This is significant to scientists because it shows that it is possible for cloned mammals to live healthy lives into old age. Listen to hear more about this encouraging milestone for cloned animals.
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.
