‘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 ....

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 Kri...

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, S...

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 ap...

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...

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...

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...

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...

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 C...

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 ex...

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...

 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 li...

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 t...

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 l...

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...

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 tran...

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 ser...

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 year jam-packed with fast-moving science news and groundbreaking research, books can provide a more slower-paced, reflective look at the world around us—and a precious chance to dive deep on big ideas. But how do you decide which scientific page-turner to pick up first? Science Friday staff  pawed through the piles  all year long. Listen to Ira round up his top picks, along with Valerie Thomp...

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 am...

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 . D...

The 2019 Ig Nobel Prize Ceremony is a tribute to offbeat and quirky scientific studies. Here's some examples: Does pizza have a protective effect against cancer? What’s the physics behind the wombat’s unusual cubic-shaped droppings? And can dog-training clickers be used to help the medical education of orthopedic surgeons?  These projects were among 10 that were recognized at this year’s  29th fir...

What can science fiction and social science  contribute to how we think about our algorithmic present and future? Science fiction writers and Hugo-winning podcast hosts Annalee Newitz (author of The Future Of Another Timeline ) and Charlie Jane Anders (author of The City In The Middle Of The Night ) talk about their work imagining future worlds and new kinds of technology—plus how all of this fict...

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. histo...

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.  C...
