Listen to learn from people who often experience cold temperatures and how some factors can affect how cold we feel more than others.
More people have been deported from the U.S. in the last decade, starting under the Obama administration, than at any other point in history.

Spanish colonization in the Americas staring in the 16th century was accompanied by the Catholic Church hoping to convert as many Native Americans to Christianity as possible.

History tells us that peaceful empires are very rare. In the 21st century, China is the fastest-growing world power. China claims that its rise is peaceful: it has no plans to invade and conquer new territory. But is it possible for any nation to grow without causing any conflicts?

Migration has been a huge part of human history. Experts agree that early humans started out in Africa and began to migrate out of Africa to different parts of Europe and Asia around 100,000 years ago. This migration occurred in waves but we don’t know why early humans left Africa. Recent research supports the theory that climate change may have been the force that drove early humans out. Looking at things such as dust, buried pollen, and coral, scientists have been able to show a correlation between changes in these things and periods in early human history of migration. As early humans looked for new food sources, the research indicates, they began to relocate. Listen to hear more about what may have caused humans to migrate.
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.
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.
Coal fueled the Industrial Revolution in England, and then America, and the whole world. But the new manufacturing came at a high price: coal pollution.

Listen to find out who these people were and how they played a role in the United States colonial history.
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.
What makes up a coral? This audio story takes you to an underwater observatory where a scientist is studying coral reefs. The scientist has found that CO2 in the ocean is making the ocean warmer and dissolving the coral reef system. But the scientist also discusses how coral reefs can recover. Listen to this story to hear the factors that threaten coral reefs and how they can recover.
When the two towers of the World Trade Center were attacked on September 11, 2001, the towers collapsed on themselves, creating a disaster area known as Ground Zero.

One journalist spent five months with unrivaled access to the recovery effort and wrote about the experience. Listen to learn more about Ground Zero and how 9/11 changed America.
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.

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.
