The answer has to do with momentum, and is explained by an expert. Listen to hear about how cats achieve this amazing feat.
Our food supply is considered safe today thanks in large part to a movement to improve safety following the publication of the novel in 1906, "The Jungle" by Upton Sinclair. It was a vivid portrayal of the lives of immigrant families who worked in a meat-packing plant in Chicago. Americans were shocked and disgusted. This public radio story tells of how "The Jungle" galvanized public support to improve the safety of our food system.
Looking back in time, it’s hard to imagine a time when there were next to no food safety regulations in the United States. But in the late nineteenth and early twentieth century, there were no laws stopping food producers from selling food that endangered the health of their customers. This all changed at the turn of the twentieth century. Listen to hear how one American chemist conducted daring experiments to publicize the damage that tainted food could cause, and how this transformed food safety regulations forever.

In the 1880s European countries divided up Africa and made them their colonies. In the 1960s, 17 of those nations gained independence. The European countries and their former African colonies still feel the effects of colonization today. France colonized nearly all of northern Africa and large parts of sub-Saharan Africa, as you can see on the map. Holding onto these countries makes France feel strong as a nation and world power. Many French leaders say they will give up their connections to their former colonies that are now independent. However, in this interview with a journalist covering Africa, we learn how France is still very involved in African states they formerly ruled.In
Consumer culture in the United States has been a fixture of the holiday season for years, particularly on the Friday after Thanksgiving–also known as “Black Friday.” That’s the inspiration for the title story in Nana Kwame Adjei-Brenyah’s latest book of speculative fiction, Friday Black. In it, he addresses the topics of race and class as they relate to American consumer culture.

Frogs are well adapted to their environment. They absorb water and oxygen through their skin which allows them to eat and breathe underwater. They are powerful jumpers and good hunters. But perhaps their most unusual adaptation is metamorphosis, the process of changing from tadpole to frog. Metamorphosis helps frogs live successfully in both wet and semi-dry environments, vary their diets, and avoid predators. Listen to hear an animal scientist explain how metamorphosis helps frogs survive, and why they eat their own tails in the process.
Fungi play a crucial role in decomposition. As they follow this process, fungi release nutrients that the trees around it absorb. Eventually, the fungi attach itself to the roots of the nature around them and begin the cycle of giving and getting to keep the environment in balance. Listen to learn how fungi first colonized land and what would happen if fungi were not able to spread.
Galileo Galilei is known as the “father of modern science.” Fascinated by gravity, motion, and the movement of heavenly bodies, Galileo’s work influences how we understand our own world and the solar system. His contributions include improving the accuracy of telescopes and adding to our understanding of gravity and, most famously, our knowledge that the earth, and other planets, revolve around the sun. The latter claim would make Galileo famous and controversial in 16th century Italy. Listen to learn about the story of Galileo Galilei and why he was sentenced to prison for his revolutionary scientific ideas.
The Great Pacific Garbage Patch is a huge area of ocean where hundreds of millions of tons of plastic garbage floats, brought there by a swirling ocean current.

Listen to hear a reporter describe what this “island of plastic” looks like, and learn what businesses and individuals, including young people, can do to help clean up ocean pollution.
The Canadian writer Margaret Atwood has published collections of poetry, short stories and essays, books for children, numerous novellas, and—the works for which she is best known—fifteen novels. Atwood’s early novels were mainly works of realistic literary fiction, the sort of novels that literary critics and academics distinguish from “genre fiction” such as mysteries and thrillers, romance novels, and science fiction and fantasy novels. Atwood has written several novels that some critics and readers would call science fiction, but which she prefers to call “speculative fiction.” In this audio story, Atwood discusses her most recent novel, "The Heart Goes Last" and explains why she feels this is not a time for realistic fiction.
Scientists say it’s nearly certain that human activity and fossil fuels are warming the planet. The mainstream discussion focuses on alternative energy and reducing fossil fuel emissions. But the field of geoengineering is looking for more large scale and proactive things we can do to offset warming. Some see this as an exciting way to help the planet, others as a threat. Listen to learn about the strategies geoengineers are exploring to prevent further global warming.

In doing so, he protested desegregation and clashed with President John F. Kennedy’s administration. Listen to hear more about George Wallace’s contentious views and his lasting impact on politics.
George Washington was the hero of the American Revolution with a victory at Yorktown in 1781. He could have used his victory to seize power, but he went home to Mount Vernon. In this audio story, the remarkable characteristics of George Washington are considered. He is a historic figure not only because he was a great general, statesman and politician, but also because he voluntarily gave up power. His action cemented the United States as a democracy, in which citizens, rather than absolute rulers, have the power to govern the nation. Listen to hear how Washington’s actions are analyzed and interpreted.
As the commander of the Continental Army in the American Revolution and our country’s first president, George Washington was one of America’s most respected leaders. Washington spent his early years working on his family’s Virginia tobacco farm and inherited the farm as a young man, after his father’s death. He was schooled at home but learned most of what he knew from hands-on experience. Listen to learn more about the early days of George Washington and the experiences that shaped his views and molded his character.
Gerrymandering is the manipulation of the boundaries of voting districts in a way that favors one political party, usually by dividing up groups of opposing voters. The U.S. Constitution gives state legislatures the authority to draw congressional districts. Often, whichever party has power in the legislature gerrymanders in its own favor. The majority of legal experts agree that gerrymandering is unfair, but is there any legal way around the Constitution? In 2015, the United States Supreme Court heard a case about the state of Arizona’s strategy for avoiding gerrymandering. Listen to this audio story to learn about the arguments for and against an approach to redistricting that does not involve the legislature.
Scientists have wondered why giant squid and colossal squid have such enormous eyes. Their eyes are the size of basketballs. Their thinking about this question has been hampered by the rarity of these animals and the difficulty of preserving eye specimens. Using some clever techniques and luck, researchers have been able to measure the size of giant squid eyes. This has led to an interesting hypothesis about why their eyes are so enormous.
Venezuela has one of the world’s largest oil reserves, but its economy has collapsed, and its government isn’t doing too well either. The country is beset by shortages—of everything. Listen to this story to find out how a country rich in natural resources has descended from wealth and democracy into financial and political chaos.
Throwing a curveball is one of the most difficult pitches in baseball. Bill Lee, a former pitcher for the Red Sox, explains how important it is to consider physics when trying to throw a curveball. Listen to learn how objects travel through space and how gravity affects a curveball.
Gravity keeps our feet on the ground, it creates a curve ball, and it can also be used to find new planets. The star at the center of our solar system maintains life on Earth and its gravitational pull creates the orbit of planets. But our sun is just one of many stars in an ever expanding universe. Alpha Centauri is the closest star system to our solar system and new technology is allowing us to better understand our neighbor. Observations of Alpha Centauri date back to 1592, but it wasn’t until 2012 that astronomers in Chile were able to identify a planet orbiting one of the stars in Alpha Centauri because of its gravitational wobble. Listen to learn more about the properties and potential of this new planet.
Even though it is the weakest of all forces, gravity is why we exist. Gravity keeps the earth, moon, and sun in orbit. It keeps us on the ground instead of floating in space. Listen to hear how gravity affects the velocity in rockets, the shapes of planets, the trajectories of baseballs, and even the strength of the human leg bones.
In 1741, New York City was shaken by an uprising led by African slaves. New York was a British colony and had a very large slave population. After a series of fires burned homes in Manhattan, including the Governor’s house, many black slaves were imprisoned, hanged, or burned.
