Clearing Carbon From Our Air

Carbon exists in all living things, including proteins, DNA, and fats. When living things exhale, the result is carbon dioxide. As our world develops, we produce more carbon dioxide with the burning of fossil fuels and the use of cars, trains, and planes. This gas is causing an imbalance in the atmosphere which affects the warming of the planet. Listen to hear how much carbon dioxide humans are responsible for and the effects of global warming.

Clinical Trials Don’t Reflect the Diversity of America

American doctors rely on clinical trials to determine which drugs to use in treatment. Researchers have found that clinical trials have not been effective in creating drugs for America’s diverse population. When clinical trials are too homogeneous, they can miss important potential discoveries. Patients who are diverse ethnically and racially can respond differently to medications, leading to dire consequences in some cases. Listen to learn how a lack of diversity in clinical trials affects patients and how researchers are trying to fix it.

Cloud Seeding for Weather Modification

There is a debate over whether cloud seeding is an efficient way to produce more snow and rain in places where droughts are the worst. Opponents claim that the chemicals that are sprayed into the air to create more water are toxic and could cause health issues in the future. Others believe this is the only way to for some gas and electric companies to obtain more energy. Listen to learn about the other concerns at hand and if this the history of this process.

Colorful Butterfly Wings

The eye-popping colors and designs on butterfly wings are not just for show, but are an important adaptation that helps the insects fend off predators. Some butterflies have wings containing toxins, signaling danger to birds and other hungry hunters. Others fold their wings for camouflage or flutter them so the colors confuse birds giving chase. Listen to hear an insect scientist explain more about the amazing ways butterflies’ colorful wings help them survive.

Cooking Up a Supervolcano

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.

Copernicus and the Center of the Universe

Until the 1500’s, it was understood that the earth was the center of the universe and that all celestial bodies revolved around it. In his book “On the Revolutions of Heavenly Spheres,” Nicolaus Copernicus challenged that accepted idea by providing evidence that, in fact, earth, along with the other planets, revolved around the sun. In this audio story, the story of Copernicus and his revolutionary idea is retold. The story delves into how and why Copernicus shared his belief with the world. The story compares the resistance to accepting Copernicus’ belief with modern debates over topics like climate change.

Creating the Vietnam War Memorial

The Vietnam War has a controversial legacy in United States history and culture. The U. S. was immersed in the conflict in Vietnam for 20 years. The draft of young men to fight far from home in the seemingly endless war led to widespread resistance and protest against the war itself. This discontent led to a disrespect of veterans when they returned. Since then the sacrifice of soldiers has been honored in memorials, movies and books. The Vietnam Veterans Memorial was built in 1982 in Washington DC. But it was controversial at the start because it honored soldiers by etching the names of the more than 58,000 soldiers killed in polished black granite. Listen to this radio story to learn the history behind this war memorial.

Da Vinci and Patterns of Tree Branches

Trees can stand up to 100-mile an hour winds during strong hurricanes. Why do some trees survive and others don’t? The answer may be in a mathematical pattern in tree growth—first observed by Leonardo da Vinci. The rule states that smaller tree branches have a precise, mathematical relationship to the branch they came from. A scientist that is studying how air flows around objects is also studying this pattern in tree branches and looking for an explanation. Listen to hear more about these observations about trees and mathematics in nature.

Design Inspiration from Nature Makes Oyster Glue

When getting knocked around by the ocean waves, a scientist realized the only things that were staying in place were the barnacles and muscles. This is due to the natural glue they produce that scientists are trying mimic to create a power glue that is non-toxic and can be used for things such as medical surgeries. Listen to learn more about how scientists developed these experiments and how this discovery could lead to a very useful resource.

Diversity in Children’s Literature

Many of the characters in books written for children don’t reflect everyone’s background. One girl became frustrated when she couldn’t connect to the characters. In response, she began to gather books about black girls and then give these books to schools. Now that she has exceeded her original goal and collected almost 4,000 books, the girl has started to consider how to impact schools in an even larger way. Listen to hear what actions this girl decided to take to promote diverse books in schools.
