Pollinators are animals that help plants reproduce by carrying pollen from one flower to another. Many plants that benefit from the help of pollinators bear fruit or nuts, providing healthy foods for people and other animals to eat. A variety of pollinators carry powdery pollen on their bodies from one flower to another, but bees are pollination superstars. Bees live in well-organized colonies and work quickly and productively. Their populations are in decline, however, and scientists are trying to understand why. Listen to hear how queen bees keep hives running smoothly and learn what can be done to help bees survive.
Alaska is home to 54 active volcanoes. Scientists, called volcanologists, watch and study these volcanoes to try and predict when they are going to erupt and so they can give warnings to the nearby communities. In 2008, Mount Redoubt, one of Alaska’s most famous volcanoes that is known to be active and dangerous, began to show signs of erupting. Listen as a volcanologist explains how taking a closer look at what goes on deep down below the surface of a volcano like Mount Redoubt can reveal warning signs that indicate a possible eruption.
Wildlife in the city? It may seem odd to hear the word “wildlife” linked to the word “city.” However, animals live wherever they can find food and shelter.

Listen to hear a scientist explain which animals can be found in suburbs and cities and how they adapt to these environments.
Wolverines are fierce predators and scavengers that live in the remote forests near the Arctic Circle. As these solitary animals need at least 500 square kilometers of space each and can travel vast distances each day, they are very difficult to spot in the wild.

Listen to hear more about this elusive mammal, including why people walking through the forest shouldn’t worry about being attacked by one.
Animals have adapted to their environments in a wide variety of ways and developed a range of survival strategies. This audio story highlights a selection of interesting animal ”superpowers,” many of which offer ecological advantages to both predators and prey. Listen to hear about the difference between poison and venom and learn how two particularly lethal creatures compare: the box jellyfish and the golden poison frog.

Dogs and humans have long had a special relationship. Part of the reason they get along so well is that dogs can understand human language, at least some of it. But why can’t they learn more? To find out, researchers played words for dogs and observed how their brains responded. Listen to learn what scientists discovered about how dogs learn words and why it’s unlikely they will ever be able to understand Shakespeare.

A recent study says teens are experiencing increased rates of depression, anxiety, and other serious mental health issues. Although the causes of the trend are not clear, some experts believe hours spent surfing online and using social media have sparked feelings of isolation and anxiety among young people. Others argue the stress stems from teens facing an uncertain future. Listen to experts discuss the roots of this troubling trend and then debate: Can social media cause depression?
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.
