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.

A team of scientists has genetically engineered pigs to be resistant to a widespread disease. Science can engineer an animal’s DNA to introduce desirable traits and get rid of negative traits or sickness. These pigs are not being raised on farms yet, but the plan is to have food from these animals available in stores in the next five years.This technology is still new, and the Food and Drug Administration has strict guidelines that have to be met before these animals will be available to the public. Listen to hear more about genetically engineered animals and then debate with your class whether you think genetically engineered animals will be safe to eat.

Humpback whales sing and continually change their songs. In the 1960’s Navy engineers used underwater microphones to record sounds in the ocean to locate enemy ships. They happened to also record whale sounds. Scientists studied these sounds and discovered that only male humpback whales sing and they gradually modify their songs. The humpback’s songs have patterns and rhythms and are not just random sounds. Listen to hear more about how sound is used to learn about the life of whales.

If you have looked closely at the eyes of different animals, you will notice their pupils come in various shapes: round, vertical or horizontal ovals or crescents. Scientists now think they know the reason behind the shape of some animals’ pupils. There is diversity in shape because it depends on how big the animal is and whether it’s a predator or prey. It also relates to their view of the horizon. Listen to hear more about the new discovery and what it can tell us about animals and evolution.

Are animals faster than humans? Common sense says horses are faster, but scientists say humans have the edge in marathon distances. Ancient man used to chase his dinner; thus, people have adapted to run long distances. This adaptation is put to the test every year in England when humans race horses on a 22-mile course through Wales. It’s an annual competition that started in 1980. Listen to find out who won the race this year and who has evolved to be faster.
