  • Building A Ghost Heart, The Effect Of Big Tech. Feb 14, 2020, Part 2

    Feb 14 2020

    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 h...more

  • Great Lakes Book Club Wrap-Up, California Groundwater. Feb 14, 2020, Part 1

    Feb 14 2020

    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...more

  • SciFri Extra: The Marshall Islands Stare Down Rising Seas

    Feb 13 2020

    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...more

  • Tech And Empathy, The Ball Method. Feb 7, 2020, Part 2

    Feb 07 2020

    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,” ...more

  • Degrees Of Change: How Native American Communities Are Addressing Climate Change. Feb 7, 2020, Part 1

    Feb 07 2020

    How Native American Communities Are Addressing Climate Change Indigenous peoples are one of the most vulnerable communities when it comes to the effects of climate change. This is due to a mix of cultural, economic, policy and historical factors. Some Native American tribal governments and councils have put together their own climate risk assessment plans. Native American communities are very diverse—and the challenges and adaptations are just as varied. Professor Kyle Whyte, a tribal member of ...more

  • Breast Cancer Cultural History, Butterfly Wings. Jan 31, 2020, Part 2

    Jan 31 2020

    ‘Radical’ Explores The Hidden History Of Breast Cancer  Nearly 270,000 women are diagnosed with breast cancer every year, along with a couple thousand men. But the disease manifests in many different ways, meaning few patients have the same story to tell.  Journalist Kate Pickert collects many of those stories in her book Radical: The Science, Culture, and History of Breast Cancer in America. And one of those stories is her own. As she writes about her own journey with breast cancer, Pickert del...more

  • Coronavirus Update, Invasive Species. Jan 31, 2020, Part 1

    Jan 31 2020

    Tracking The Spread Of The Coronavirus Outbreak This week, the World Health Organization declared that the coronavirus outbreak—which began in Wuhan, China—is a public health emergency of international concern. Nearly 8,000 cases have been confirmed worldwide. Chinese scientists sequenced the genome of the virus from some of the patients who were infected early on in the outbreak. Virologist Kristian Andersen discusses how the genetics of the virus can provide clues to how it is transmitted and ...more

  • SciFri Extra: Revisiting Unique Science Stories Of 2019

    Jan 28 2020

    2020 has just begun, but we’re still celebrating all the amazing work done by science journalists in 2019. Thanks to them, we’ve been informed on stories like the new illnesses linked to vaping, the first image of a black hole, and the increase in youth-led climate change protests. At our year in review event at Caveat in NYC on December 18, 2019, three science storytellers—Arielle Duhaime-Ross, Sarah Zhang, and Ariel Zych—took the stage with a notable story they reported in 2019, including the ...more

  • Coronavirus, Great Lakes Drinking Water. Jan 24, 2020, Part 1

    Jan 24 2020

    A novel coronavirus—the type of virus that causes SARS, Middle East Respiratory Syndrome (MERS), and common cold symptoms—has killed 18 people, and sickened more than 600. In response, Chinese officials have quarantined several huge cities, where some 20 million people live. In this segment, Ira talks with epidemiologists Saskia Popescu and Ian Lipkin about what we know about the virus, how it appears to spread, and whether efforts to contain it are effective—or ethical.  Do you know where your...more

  • Feathered Dino, Clinical Trials, Coffee Extraction. Jan 24, 2020, Part 2

    Jan 24 2020

    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 ou...more

  • Polling Science, Gar-eat Lakes. Jan 17, 2020, Part 1

    Jan 17 2020

    The Science Of Polling In 2020 And Beyond In today’s fast-paced digital culture, it is more difficult than ever to follow and trust political polls. Campaigns, pollsters, and media outlets each say that their numbers are right, but can report different results. Plus, the 2016 election is still fresh in the public’s mind, when the major story was how political polling got it wrong.  But despite how people may feel about the practice, the numbers suggest that polls are still working. Even as telep...more

  • Biorobots, The Math Of Life, Science Comics. Jan 17, 2020, Part 2

    Jan 17 2020

    Living Robots, Designed By Computer Researchers have used artificial intelligence methods to design ‘living robots,’ made from two types of frog cells. The ‘xenobots,’ named for the Xenopus genus of frogs, can move, push objects, and potentially carry materials from one place to another—though the researchers acknowledge that much additional work would need to be done to make the xenobots into a practical tool. The research was published in the Proceedings of the National Academy of Sciences. Jo...more

  • Migraines, Galaxy Formation. Jan 10, 2020, Part 2

    Jan 10 2020

    The Mysteries Of Migraines What do sensitivity to light, a craving for sweets and excessive yawning have in common? They’re all things that may let you know you’re about to have a migraine. Of course each person’s experience of this disease—which impacts an estimated 38 million people in the U.S.—can be very different. One person may be sensitive to light while another is sensitive to sound. Your pain may be sharp like a knife while your friend’s may be dull and pulsating. Or perhaps you don’t h...more

  • Australia Fires, Great Lakes Book Club. Jan 10, 2020, Part 1

    Jan 10 2020

    How Climate Change Is Fanning Australia’s Flames  All eyes have been on Australia in recent weeks as the country’s annual summer fire season has spun out of control with devastating damage to endangered wildlife, homes, farms, indigenous communities, and—as smoke drifts across unburned major metropolitan centers like Sidney and Canberra—air quality.  Vox reporter Umair Irfan and fire scientist Crystal Kolden explain why climate scientists are pointing the finger squarely at climate change for co...more

  • Geoengineering Climate Change, Tasmanian Tiger, New Water Plan. Jan 3, 2020, Part 1

    Jan 03 2020

    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...more

  • Christmas Bird Count. Jan 3, 2020, Part 2

    Jan 03 2020

    For many, the new year means looking back on the past accomplishments and checking off your goals. For birders, it means tallying up your species list and recording all the birds you’ve spotted in the season. Birders Corina Newsome and Geoff LeBaron, director of the National Audubon Society’s Christmas Bird Count, guide us through the feathered friends flying overhead—from nuthatches to ducks to merlins. 

  • 2019 Year In Review. Dec 27 2019, Part 1

    Dec 27 2019

     In 2019 we experienced some painful and heartbreaking moments—like the burning of the Amazon rainforest, a worldwide resurgence of measles cases, and the first ever deaths linked to vaping.  Ira talks with this year’s panel of science news experts, Wendy Zukerman, Rachel Feltman, and Umair Irfan, live on stage at Caveat in New York City.  Plus, as we turn the corner into 2020, Science Friday listeners weigh in with their picks for the best science moment of the decade. 

  • Looking Back at the Pale Blue Dot. Dec 27, 2019, Part 2

    Dec 27 2019

    Few people could put the cosmos in perspective better than astronomer Carl Sagan. And that’s why we’re taking this opportunity to take another listen to this classic conversation with Sagan, recorded December 16, 1994, twenty-five years ago this month.  Ira and Sagan talk about US space policy, the search for extraterrestrial intelligence, the place of humans in the universe, and humanity’s need to explore.     

  • Emerging Technologies, Pokémon In The Brain, Colds And Flu. Dec 20, 2019, Part 1

    Dec 20 2019

    Back when Science Friday began in 1991, the Internet, as we know it, didn’t even exist. While ARPA-NET existed and the first web pages began to come online, social media, online shopping, streaming video and music were all a long ways away. In fact, one of our early callers in 1993 had a genius idea: What if you could upload your credit card number, and download an album you were interested in listening to? A truly great idea—just slightly before its time. In this segment, we’ll be looking ahead...more

  • Space Junk, Chronobiology, Mistletoe. Dec 20, 2019, Part 2

    Dec 20 2019

    As more commercial companies are getting into the satellite launching game, space is becoming a crowded place and all of these objects are creating space debris. Right now, there are approximately 2,000 satellites floating in low-Earth orbit. Space agencies have estimated that are over 100 million small particles floating in low-Earth orbit, but there are no large scale projects to clean up these pieces of space trash.  Aerospace engineer Moriba Jah and space archeologist Alice Gorman talk about...more

  • Degrees of Change: Transportation. December 13, 2019, Part 1

    Dec 13 2019

    Transportation—whether it be your car, aircraft, cargo ships, or the heavy trucks carrying all those holiday packages—makes a big contribution to the world’s CO2 emissions. In the U.S., the transportation sector accounts for some 29% of the country’s emissions, according to Environmental Protection Agency data. And despite the Paris Agreement mission to decrease global emissions, demand for transportation around the world is on the rise—and with that increased demand comes increased energy use. ...more

  • Insulin Marketplace, Hair, Whale Size. December 13, 2019, Part 2

    Dec 13 2019

    Why Diabetes Patients Are Getting Insulin From Facebook Almost one in ten Americans are diagnosed with diabetes, according to the most recent statistics from the CDC. With those odds, you likely know someone with the disease. And you may also know that most diabetes patients need to be treated with insulin therapy—frequent injections of a hormone that helps regulate their blood sugar—or face serious complications, like blindness, nerve damage, or kidney failure.  Unfortunately, a good number of ...more

  • Undiscovered Presents: Spontaneous Generation

    Dec 11 2019

    These days, biologists believe all living things come from other living things. But for a long time, people believed that life would, from time to time, spontaneously pop into existence more often—and not just that one time at the base of the evolutionary tree. Even the likes of Aristotle believed in the “spontaneous generation” of life, until Louis Pasteur debunked the theory—or so the story goes.  In a famous set of experiments, Pasteur showed that when you take a broth, boil it to kill all th...more

  • Best Science Books and Board Games of 2019. Dec 6, 2019, Part 2

    Dec 06 2019

    In August 2018, NASA sent the Parker Solar Probe off on its anticipated seven-year-long mission to study the sun. Already, it has completed three of its 24 scheduled orbits, and data from two of those orbits are already telling us things we didn’t know about the star at the center of our solar system. The probe has collected information on the factors that influence the speed of solar wind, the amount of dust in the sun’s bubble-like region—the heliosphere—and also where scientists’ models were ...more

  • SciFri Extra: Bringing Environmental Justice To The Classroom

    Nov 30 2019

    Laura Diaz, a Bay Area science teacher, grew up in Pittsburg, California near chemical plants and refineries. That experience, combined with watching her mother’s home go up in flames in last year’s Camp Fire, transformed her into an “environmental justice activist.” Now, she’s bringing those experiences into the classroom to inspire young people to solve the world’s injustices through science. Diaz joined Ira onstage at San Francisco’s Sydney Goldstein Theater, alongside a few former students, ...more

  • Undiscovered Presents: Planet Of The Killer Apes

    Nov 27 2019

    In Apartheid-era South Africa, a scientist uncovered a cracked, proto-human jawbone. That humble fossil would go on to inspire one of the most blood-spattered theories in all of paleontology: the “Killer Ape” theory.  According to the Killer Ape theory, humans are killers—unique among the apes for our capacity for bloodthirsty murder and violence. And at a particularly violent moment in U.S. history, the idea stuck! It even made its way into one of the most iconic scenes in film history. Until a...more

  • Degrees of Change: Coral Restoration. Nov 22 2019, Part 1

    Nov 22 2019

    A quarter of the world’s corals are now dead, victims of warming waters, changing ocean chemistry, sediment runoff, and disease. Many spectacular, heavily-touristed reefs have simply been loved to death. But there are reasons for hope. Scientists around the world working on the front lines of the coral crisis have been inventing creative solutions that might buy the world’s reefs a little time.  Crawford Drury and his colleagues at the Hawaii Institute of Marine Biology are working to engineer m...more

  • Astronaut Kathryn Sullivan, Marie Curie Play. Nov 22, 2019, Part 2

    Nov 22 2019

    For most Americans, the story of the Hubble Space Telescope began on April 24th, 1990, the launch date of the now 30 year-old observatory. But for astronaut Kathryn Sullivan, Hubble’s journey began on a wintery day in early 1985 at a meeting at NASA headquarters, where she was assigned to the mission that would take Hubble into space.  For the next five years, Sullivan, a former oceanographer and first female spacewalker, got to know Hubble intimately, training and preparing for its deployment. ...more

  • Undiscovered Presents: Like Jerry Springer For Bluebirds

    Nov 20 2019

    “Do men need to cheat on their women?” a Playboy headline asked in the summer of 1978. Their not-so-surprising conclusion: Yes! Science says so! The idea that men are promiscuous by nature, while women are chaste and monogamous, is an old and tenacious one. As far back as Darwin, scientists were churning out theory and evidence that backed this up. In this episode, Annie and Elah go back to the 1970s and 1980s, when feminism and science come face to face, and it becomes clear that a lot of anima...more

  • Volume Control, Dermatology In Skin Of Color, Kelp Decline. Nov 15, 2019, Part 2

    Nov 15 2019

    Dermatologists presented with a new patient have a number of symptoms to look at in order to diagnose. Does the patient have a rash, bumps, or scaling skin? Is there redness, inflammation, or ulceration? For rare conditions a doctor may have never seen in person before, it’s likely that they were trained on photos of the conditions—or can turn to colleagues who may themselves have photos. But in people with darker, melanin-rich skin, the same skin conditions can look drastically different, or be...more

  • EPA Transparency Proposal, Tick Milking. Nov 15, 2019, Part 1

    Nov 15 2019

    This week, a House Committee held a hearing to review an Environmental Protection Agency proposal called ‘Strengthening Transparency in Regulatory Science.’ The proposal would require researchers to disclose underlying data—which could include private medical and health information—for any scientific studies that the agency would use in determining environmental regulations. Science reporter Lisa Friedman from the New York Times discusses how this proposal could be used to weaken regulations and...more

  • Infant Formula, AI Weirdness, Venus Fly Traps. Nov. 8, 2019, Part 2

    Nov 08 2019

    Would you feel comfortable consuming a product that listed “whey protein concentrate” and “corn maltodextrin” on its list of ingredients? What about feeding it to your baby? Most of the ingredients found in baby formula are actually just carbohydrates, fats, and proteins, and are perfectly safe—and necessary—for infant health. But this inscrutable list of ingredients is one reason why many parents are opting to buy European formula for their little ones. Word is spreading around parenting blogs ...more

  • Biomedical Espionage, Einstein’s Eclipse, Transit Of Mercury. Nov. 8, 2019, Part 1

    Nov 08 2019

    The FBI, National Institutes of Health (NIH), and other agencies who oversee federal research grants are currently asking if the open culture of science in the U.S. is inviting other countries to steal it. The FBI has been warning since 2016 that researchers could be potentially sending confidential research, and even biological samples, to other countries. On Monday, a report in the New York Times outlined the scale of ongoing investigations: nearly 200 cases of potential intellectual property ...more

  • Moths, Alan Alda, Graveyard Lichens. Nov 1, 2019, Part 2

    Nov 01 2019

    There are over 160,000 species of moths worldwide, and they come in all different shapes and sizes. For example, the Comet Moth, native to the rainforests of Madagascar, boasts vibrant red and yellow patterned wings, feathery antennae, and long swapping tails, thought to useful for distracting its bat predators. By comparison, most common North American moths seem boring and dull. While their butterfly relatives flit about the garden in daylight, moths are often found lurking around outside lamp...more

  • PFAS Lawsuit, Bat Disease. Nov 1, 2019, Part 1

    Nov 01 2019

    Eighteen years ago, a lawyer named Robert Bilott sent a letter to the EPA, the attorney general, and other regulators, warning them about a chemical called PFOA, short for perfluorooctanoic acid. Outside of the companies that made and used PFOA, most people had never heard of it. But E.I. du Pont de Nemours and Company, better known as DuPont, had been using PFOA to make Teflon since the early 1950s. In the course of a lawsuit against the chemical corporation, Bilott had uncovered a trove of int...more

  • “Black Software” Book, Mucus. Oct 25, 2019, Part 2

  • Spiders, Quantum Supremacy, Missouri Runoff. Oct 25, 2019, Part 1

    Oct 25 2019

    Spiders were one of the first animals to evolve on land. And over the span of 400 million years of speciation and evolution, they’ve learned some amazing tricks. One of their trademarks? The strong, sticky substance that we call silk—every spider produces it, whether for weaving webs, wrapping prey, or even leaving trails on the ground for potential mates.  But every silk is unique, each with different chemistry and different physical properties. Even a single spider web may use multiple kinds o...more

  • Policing And Mental Health, Ancient Clams, Moon Plan. Oct. 18, 2019, Part 2

    Oct 18 2019

    In the 1980s and 1990s, in the midst of rising crime rates and a nationally waning confidence in policing, law enforcement around the country adopted a different approach to addressing crime. Instead of just reacting to crime when it happened, officers decided they’d try to prevent it from happening in the first place, employing things like “hot spots” policing and “stop and frisk,” or “terry stops.” The strategy is what criminologists call proactive policing, and it’s now become widely used in ...more

  • Degrees Of Change: Climate Change Migration. Oct. 18, 2019, Part 1

    Oct 18 2019

    When the water rises, whether from heavy rains or rising seas, communities have a few options: reinforce flood-threatened homes, rebuild after the water recedes, or—in places where the threat of repeated floods and even more damage is increasing—leave. And while leaving may feel synonymous with defeat, more cities and states are interested in encouraging people to leave risky floodplains—a process called managed retreat. FEMA offers a buyout program that usually involves offering homeowners mone...more

    Oct 11 2019

    If you live and work in an urban area, you might think about the air quality outside your home or workplace. But what about the air quality inside the office? It turns out that on average, indoor environments have higher concentrations of potentially harmful substances, such as aerosols and volatile organic compounds (VOCs). While past research has focused on chemical emissions from building materials, cleaning supplies, and even furniture, air pollution researchers are increasingly looking at a...more

  • Trust In Science, California Power Outages, Regrowing Cartilage. Oct 11, 2019, Part 1

    Oct 11 2019

    Despite widely reported attacks on science, the vast majority of Americans continue to trust scientists, according to the latest survey from the Pew Research Center. Many listeners of Science Friday might take it as a given that we should trust science, but is that trust well-founded? Naomi Oreskes, history of science professor at Harvard University, argues that we should. In her new book, Why Trust Science?, she explains how science works and what makes it trustworthy. (Hint: it’s not the scien...more

    Sep 27 2019

    A new report issued this week by the UN’s Intergovernmental Panel On Climate Change paints a troubling picture of the world’s ice and oceans. The ocean effects of climate change, from warming waters to ocean acidification to sea level rise, are already altering the weather, fisheries, and coastal communities. The authors of the report state that the ocean has already taken up more than 90% of the excess heat in the climate system since 1970, the surface is becoming more acidic, and oxygen is bei...more

  • Bird Populations In Decline, Real Life Sci-Fi Disasters, Brain Wiring. Sept 20, 2019, Part 2

    Sep 20 2019

    There may be almost 3 billion fewer birds in North America today than there were in 1970, according to a study published this week in the journal Science. The decline over time works out to a loss of about one in 4 birds. However, the decline does not appear to be evenly distributed. Then, journalist Mike Pearl investigates what the world would look like after technology breakdowns, a real-life Jurassic Park, and other sci-fi doomsday scenarios in his book, The Day It Finally Happens. Finally, n...more
