Debate: Are Deliveries by Robots a Good Idea?

Technology

Instead of going to a restaurant to pick up food, you can have it delivered to your home. That’s nothing new. But some restaurants are experimenting with using a robot to deliver orders. The robot is equipped with cameras that allow it to observe the street signs, lights, and roads around them to know how and when to cross streets. Some fear this invention may replace jobs held by people, but the company says they are not a replacement for humans. Listen to learn the capabilities of these delivery robots and then debate: Are deliveries by robots a good idea?

Cow Burping and Greenhouse Gases

conservation

Greenhouse gases trap heat in Earth’s atmosphere, contributing to climate change. One of the most common greenhouse gases is methane. In the United States, cars and industry are the primary sources of greenhouse gases. In Africa, which has more agriculture than industry, burping cows are the main producers of methane gas. Researchers have found that African and American cows are actually quite different from each other in the amount of methane in their burps. African scientists are studying how cows’ diets affect their methane production. Listen to hear how cow burps affect the environment.

Dinosaur-Eating Crocodile

Life Science biology

A teenager recently discovered what turned out to be the fossil of a large, dinosaur-eating crocodile in northern Texas. Many amateur fossil hunters enjoy looking for ancient animals’ bones in this rocky area. At the site, for example, a combination of harsh living conditions exposed dirt makes it easier to uncover all sorts of fossils. An expert explains how fossil hunters help him discover ancient species. He also describes why dinosaurs fascinate us and how they can help us learn more about science. Listen to learn more about this dinosaur-eating crocodile.

Volcanic Eruption in Hawaii

Earth and Space Science Physical Science

On Hawaii’s Big Island, the Kilauea volcano sent a pool of lava back underground causing small earthquakes. At least 1,500 residents were ordered to evacuate after the volcano erupted. In some neighborhoods, lava is splitting the ground open and exposing molten rock that can shoot high in the air. The lava has covered over an acre of land and hundreds of small earthquakes have been shaking the ground. The Governor and National Guard have been working to ensure the safety of all residents. Listen to hear more about the volcano and earthquakes in Hawaii.

Cooking Up a Supervolcano

Life Science Earth and Space Science Geology

Giant volcanoes appear every few million years, and their eruptions are rare, but they are deadly. The ash and gas released into the atmosphere have the potential for significant harm. So scientists are studying two new suspected volcanic “hot spots" and are trying to figure out why they erupt. Listen to learn how seismic waves give scientists a picture of the large regions where intense volcanic activity could develop in the distant future.

World’s Best-Known Scientist, Stephen Hawking

Earth and Space Science

Stephen Hawking was considered by many to be the greatest scientist of his generation. He was brilliant and funny and authored a best selling book titled “A Brief History of Time.” He had ALS, a disease that led to his paralysis. But he was able to overcome his adversity and do great work as a scientist by using a speech-generating device with the muscles in his cheek. As a theoretical physicist, his work explored the mysteries of the universe and black holes and inspired millions of people. Listen to this story about Stephen Hawking’s life and accomplishments.

Melting Permafrost Exposes Carbon

Climate Change Weather and Climate

Permafrost is frozen soil that has preserved things such as ancient animal bones and centuries-old icebergs. Permafrost contains twice as much carbon as is currently in Earth's atmosphere and it also preserves old bacteria. When it's defrosted the bacteria eats dead plants and animals turning their carbon into gases such as carbon dioxide. As the permafrost warms, the microbes are releasing gases contributing to further warming. Listen to learn more about this warming cycle.

An estimated 1 in 13 children have food allergies. Some are potentially life-threatening and avoiding the allergen can be challenging and stressful. The blood tests and skin prick tests rule out specific food allergies but are not as accurate when confirming food allergies. The oral food challenge, where the food is eaten under the supervision of a doctor has become the gold-standard for determining allergies. Listen to this story about allergies as a health concern and the best way to tell if the food allergies have been outgrown.
