At the turn of the 19th century, Britons would stroll along the Yorkshire Coast, stumbling across unfathomably big bones. These mysterious fossils were all but tumbling out of the cliffside, but people had no idea what to call them. There wasn’t a name for this new class of creatures. Until Richard Owen came along. Owen was an exceptionally talented naturalist, with over 600 scientific books and papers. But perhaps his most lasting claim to fame is that he gave these fossils a name: the dinosaur...

60 years ago this year, a young Jane Goodall entered the Gombe in Tanzania to begin observations of the chimpanzees living there. During her time there, Goodall observed wild chimpanzees in the Gombe making and using tools—a finding that changed our thinking about chimps, primates, and even humans. Now, Goodall travels the world as a conservationist, advocate for animals, and United Nations Messenger of Peace. She joins guest host John Dankosky to reflect on her years of experience in the field ...

For centuries, smallpox seemed unbeatable. People had tried nearly everything to knock it out—from herbal remedies to tossing back 12 bottles of beer a day (yep, that was a real recommendation from a 17th century doctor), to intentionally infecting themselves with smallpox and hoping they didn’t get sick, all to no avail. And then, in the 18th century, an English doctor heard a rumor about a possible solution. It wasn’t a cure, but if it worked, it would stop smallpox before it started. So one s...

The Farm Crisis of the 1980s was a dark time for people working in food and agriculture. U.S. agricultural policies led to an oversupply of crops, price drops, and farms closures. At the same time, the rate of farmer suicide skyrocketed. The industry struggled, until organizations like Farm Aid and others popped up to give voice to the crisis. But farm advocates agree that farmers are in the middle of another period of hardship, one brought on by the same factors that caused the Farm Crisis in t...

The number of people in the U.S. confirmed to be infected with the pandemic-level respiratory coronavirus continues to rise, even as testing and diagnosis capacity continues to lag behind other nations. In the meantime, epidemiologists are urging people all over the country to take actions that help “flatten the curve,” to slow the rate of infection so the number of cases don’t overwhelm the healthcare system and make the virus even more dangerous for those who get it. And the best methods to fl...

Remember that summer when the internet was one Distracted Boyfriend after another—that flannel-shirted dude rubbernecking at a passing woman, while his girlfriend glares at him? Everyone had their own take—the Boyfriend was you, staring directly at a solar eclipse, ignoring science. The Boyfriend was youth, seduced by socialism, spurning capitalism. The Boyfriend could be anyone you wanted him to be. We think of memes as a uniquely internet phenomenon. But the word meme originally had nothing to...

This week, the world’s attention has turned to the spread of the novel coronavirus, SARS-CoV-2, that was first detected in Wuhan, China, late in 2019. More countries are finding cases, and in the United States, a California patient has become the first known case of possible “community spread”—where the patient had not traveled to affected areas or had known exposure to someone who had been infected. On Tuesday, the Centers for Disease Control said Americans should prepare for “significant disru...

In order to slow a warming planet on track to increase by 2 degrees celsius, nearly every industry will be forced to adapt: airlines, fashion, and even the unglamorous and often overlooked building materials sector. Just like the farm to table movement, consumers are increasingly thinking about where the raw materials for their homes and cities come from, and how they impact climate change. And in response to this concern, the materials sector is serving up an unusual menu option: wood. “Mass ti...

What Is Real And Fake? There are two ways to grow a diamond. You can dig one up from the Earth—a product of billions of years of pressure and heat placed on carbon. Or you can make one in a lab—by applying lots of that same heat and pressure to tiny starter crystals—and get it made much faster. Put these two objects under a microscope and they look exactly the same. But is the lab-grown diamond real or fake? The answer lies somewhere in between. The same goes for many other things, like artifici...

The human heart is one of the most complicated organs in our body. The heart is, in a way, like a machine—the muscular organ pumping about 2,000 gallons of blood in an adult human every day. But can we construct a heart in the lab? Some scientists are turning to engineering to find ways to preserve that constant lub dub when a heart stops working. One team of researchers created a biohybrid heart , which combines a pig heart and mechanical parts. The team could control the beating motion of the ...

The Great Lakes hold 20% of the world’s surface drinking water, with Lake Superior holding half of that alone. The lakes stretch from New York to Minnesota, and cover a surface area of nearly 100,000 square miles—large enough to cover the entire state of Colorado. And they’re teeming with life. Fish, phytoplankton, birds, even butterflies call the lakes home for some portion of their lives. But not all is calm in the waters. In The Death and Life of the Great Lakes, journalist Dan Egan tells the...

The Republic of the Marshall Islands is a country of 58,000 people spread across 29 coral atolls in the Pacific Ocean. And in a world where seas are both rising and acidifying, the Marshall Islands are exceptionally vulnerable: Those atolls rise a mere two meters above the original ocean height on average, and rely on the health and continued growth of their coral foundations to exist. A 2018 study projects that by 2050, the Marshall Islands could be mostly uninhabitable due to salt-contaminated...

How Tech Can Make Us More—And Less—Empathetic Much of technology was built on the promise of connecting people across the world, fostering a sense of community. But as much as technology gives us, it also may be taking away one of the things that makes us most human—empathy. Meet Alice Ball, Unsung Pioneer In Leprosy Treatment In 1915, an infection with leprosy (also called Hansen’s disease) often meant a death sentence. Patients were commonly sent into mandatory quarantine in “leper colonies,” ...

Before any new drug comes to market, it goes through a time-consuming process. Researchers have to recruit human subjects for a clinical trial, collect all the data, and analyze the results. All of that can take years to complete, but the end result could be worth it: a drug that treats a rare disease or improves patients lives with fewer side effects. Or the opposite could happen: The drug doesn’t have any effect or makes patients worse. So the question is, how is the public informed of the out...

In the context of climate change, geoengineering refers to deliberate, large-scale manipulations of the planet to slow the effects of human-induced global warming—whether by removing carbon from the atmosphere and storing it safely, or altering the atmosphere to reflect the amount of incoming sunlight that is absorbed as heat. But neither strategy is uncomplicated to deploy . Carbon capture is expensive and is often used to enhance fossil fuel extraction, not to actually reduce emissions. Meanwh...
