The case presented a medical mystery. A man had entered his doctor’s office complaining of chest pain, so his doctors ordered an angiogram, an X-ray of the arteries of his heart. His condition was serious: a complete blockage of one of his coronary arteries, and a severe dysfunction of his left ventricle. The doctor realized his patient had been having a heart attack for more than 24 hours. On the face of it, nothing would seem unusual about the case. Heart disease is the number one killer of men and women in the U.S., claiming more than 600,000 lives a year. But this case was different. This man had none of the risk factors. He wasn’t diabetic, or a smoker, and had no hypertension. Even more confounding: He was only 30 years old. He was, however, of South Asian descent—a group that suffers a disproportionate risk of heart problems with no obvious cause, according to cardiologist Sandeep Jauhar. Jauhar writes about that, and the daring and sometimes tragic treatments that revolutionized how we fix the heart, in his new book Heart: A History. He joins guest host Flora Lichtman to talk about it. You’ve heard of flu season, of course […]
Science Friday, as heard on NPR, is a weekly discussion of the latest news in science, technology, health, and the environment hosted by Ira Flatow. Ira interviews scientists, authors, and policymakers, and listeners can call in and ask questions as well. Watch the latest science videos from the Science Friday website.
With the midterm elections less than a week away, science is on voters’ minds even when it’s not on the ballot. From coastal floods in Florida, to the growing pains of renewable energy in Hawaii, to curbing the opioid addiction crisis in Kentucky, different stories hit closer to home depending on what state you’re in. We’ll share stories of salmon conservation policy, meat substitute labeling, renewable energy expansion, and more from their respective states. And they take listener input: What’s the most important science story YOU see in your state? The oceans can be a noisy place filled with boats and an increasing number of wind farms. The animals who call the sea home have had to adapt to the increased sounds. Researchers found that bottlenose dolphins in the Atlantic ocean off the coast of Maryland were simplifying the calls that they use to identify one another. Their results were published in the journal Biology Letters. Marine biologist Helen Bailey, who was an author on that study, talks about the benefits and costs that these adaptations have on the health of these dolphins. This week, NASA announced we will soon be saying goodbye to another old friend. For nine years, NASA’s Kepler […]
Blood is essential to human life—it runs through all of our bodies, keeping us alive—but the life-giving liquid can also have a mysterious, almost magical quality. As journalist Rose George points out, this association goes back to thousands of years, even showing up in “The Odyssey.“ Odysseus, while traveling in Hades, comes across his mother Anticlea, who will not speak to him. At least, she says, “Not until she drinks the blood that Odysseus has taken from reluctant sheep. For Homer, blood had a power as fierce and invisible as electricity: a mouthful of blood, a switch flicked, and Anticlea could now speak to her son.” George’s new book, “Nine Pints: A Journey Through the Money, Medicine, and Mysteries of Blood,” traces the cultural significance and business of blood. She talks about how we’ve tried to harness blood through the idea of the blood banking happened in 1937 at Chicago’s Cook County Hospital and the search for possible synthetic substitutes. Take a deep breath in. With one single inhalation, the human nose takes in a bunch of information about your environment. And unlike vision and hearing, that information goes straight to the limbic system, the part of the brain that […]
Mark Ramos Nishita, more popularly known as Money Mark from the Beastie Boys, has created the “Echolodeon.” The custom-built machine converts original piano rolls, created from actual performances by greats like Debussy and Eubey Blake, into MIDI signals routed through modern-day synthesizers. Step aside, honeybees, there’s a new pollinator in town. We talk about the intricate life cycle of bumblebees, whose queens spend most of their life cycles solitary and underground, but then emerge in the spring to single-handedly forage for food, build a nest, and start colonies that eventually grow to number hundreds. Researchers study the behavior of bees and other social insects, and why ant, bee, and spider societies are more than just an amalgam of individuals—but collective behaviors that emerge from the masses. How did you sleep last night? If you’re one of the estimated one in three American adults who gets less than seven hours of sleep per night, you may not want to answer that one. As researchers cement the connection between sleep and health, others are still asking why some people have fewer problems sleeping, and others recover more easily from lost sleep. We’ll talk about where our genes come into the picture when it comes to sleep. About the […]
The World Health Organization recommends that the C-section rate should be about 15% of births, for optimal outcomes for mothers and babies. But a series of studies published in The Lancet this week shows that rates worldwide are much higher. In the past 15 years, worldwide rates have nearly doubled. In the United States, one out of three children are born through the procedure. At the same time, the rate varies within countries—showing certain communities may have limited access lifesaving procedures. Even before Hurricane Maria roared across Puerto Rico, much of the food on the island was imported. Nearly a year after the storm, farmers still grapple with the storm’s effects. Travis Thomas is a rookie scientist on the verge of publishing his first paper. He’s about to name two new species of alligator snapping turtle when he’s scooped by Raymond Hoser, an amateur herpetologist who goes by the name, “The Snakeman.” Hoser has named hundreds of animals using methods that some scientists call sloppy. The latest episode of Undiscovered uncovers how an outsider is able to use the scientific communities rules against it. About the “Science Friday” Podcast
