New NASA Science Head, Climate and Fungus, Whiskey Fungus, Animal Testing Alternatives. March 24, 2023, Part 2
Can Medicine Move To Animal-Free Testing? Before a new drug can begin clinical trials in humans, it gets tested on animals. But things are changing. Late last year, Congress passed the FDA Modernization Act 2.0, which cleared the way for new drugs to skip animal testing. Can we expect to phase out animal testing altogether? Is it safe? And what technologies might make that possible? Guest host Flora Lichtman talks with Dr. Thomas Hartung, director of the Johns Hopkins Center for...

And to no one’s surprise, this year’s report is full of warnings. But also, it has a lot of room for hope. Maggie Koerth, senior science writer at FiveThirtyEight, joins guest host Charles...
Smart Toilet, Soft Robotics, Naked Mole Rats. March 17, 2023, Part 2
Stop Flushing Your Health Data Down The Toilet You could be flushing important information about your health right down the toilet—quite literally. Pee and poop can tell you a lot about your health, so what if your waste…didn’t go to waste? What if, instead, it could tell you more about your health? Like number one, it can catch a condition like diabetes early. Or number two, check out what’s going on in your gut microbiome. That’s the goal of the smart toilet—a device that gets all up in...
Drugs Designed By AI, The Phosphorus Paradox, Regulating PFAS Chemicals. March 17, 2023, Part 1
At Long Last, More Regulations For Forever Chemicals This week, the EPA proposed the first national standards for drinking water that would set limits on the amount of PFAS (per- and polyfluoroalkyl substances) chemicals that would be allowed in water systems. There are thousands of different PFAS chemicals, which are often used industrially for properties such as heat, water and stain resistance—from fire-fighting foams to coatings on clothing and paper plates. They have come to be known...

Science At The Oscars, Finding Shackleton’s “Endurance” Ship. March 3, 2023, Part 1
Insulin Maker Eli Lilly Finally Caps The Drug’s Cost In 1923, drug manufacturer Eli Lilly became the first company to commercialize insulin. Since then, its cost has skyrocketed. But this week, the company announced that it is capping the cost of insulin at $35. This comes as a huge relief to many Americans, since insulin has become the face of pharmaceutical price gouging. Over the last 20 years, the price of insulin has grown by six times, making this essential, life-saving drug...
Social Media’s ‘Chaos Machine,’ Whale Vocal Fry, Distant Galaxies. March 3, 2023, Part 2
Inside The ‘Chaos Machine’ Of Social Media Despite social media’s early promises to build a more just and democratic society, over the past several years, we’ve seen its propensity to easily spread hate speech, misinformation and disinformation. Online platforms have even played a role in organizing violent acts in the real world, like genocide against the Rohinga people in Myanmar, and the violent attempt to overturn the election at the United States capitol. But how did we get here? Has...
AI And Hip Hop, Self-Planting Seeds, Abortion Pill Facing Restrictions. Feb 24, 2023, Part 1
A Medication Abortion Drug Faces Potential Nationwide Restriction A federal court case underway in Texas this week could have big implications for medication based abortion care across the U.S. The case involves the FDA’s approval of the drug mifepristone, which is used as part of a two-drug combination in most medication abortions. The plaintiffs in the case are arguing that the FDA went against its own guidelines regarding drug safety when it approved the medication in 2000, though the...

Spy Balloons, Cost of Cancer Care, Seaweed, Chocolate Mouthfeel. Feb 17, 2023, Part 2
Eyes In The Sky: The Science Behind Modern Balloons This month, the news cycle has been dominated by updates about suspicious objects being detected in the stratosphere. This bonanza started with a balloon from China, and escalated as four more objects—not all confirmed as balloons—have been shot down from the sky. Although this might sound like a new problem, there are probably thousands of balloons floating above us—some for spying, others for exploring near space, or studying weather...
Ohio Train Spill, Mushroom And Memory, Water Infrastructure. Feb 17, 2023, Part 1
UFOs? Balloons? Spy Cams? Here’s What’s Going On This week, the saga over UFOs, balloons, and spyware continues. The drama all started with a Chinese surveillance balloon, and then—one by one—governments kept finding others in the U.S. and Canada. Earlier this week, President Biden announced, “We don’t know yet exactly what these three objects were. But nothing right now suggests they are related to China’s spy balloon program or that they were surveillance vehicles from any other country.”...

But nature recordist Juan Pablo Culasso, based in Bogata, Colombia, is changing that. He’s designed a system of fully accessible trails in the cloud forests of southwest Colombia...
Art Crime Science, Long Covid Update, Earth's Slowing Core. Jan 27, 2023, Part 1
What’s Behind The Strange Slowing Of The Earth’s Core? Even though some days feel more chaotic than others, the rotation of the surface of the planet proceeds at a pretty constant rate—about one full rotation every 24 hours. But the rotational speed of the inner core is less stable, and has been known to shift over time. Now, researchers are reporting in the journal Nature Geoscience that according to seismic data, the Earth’s inner core may have recently paused its rotation, and could even...
Gas Stoves, Next Gen Vaccines, Printed Violins. January 20, 2023, Part 2
Why Are Gas Stoves Under Fire? If you were online at all last week, you probably encountered conversations about gas stoves. The sudden stove discourse was sparked by a comment made by a commissioner on the Consumer Products Safety Commission (CPSC) to a Bloomberg reporter, in which the commissioner discussed plans to regulate gas stoves. Those comments morphed via repetition into inaccurate rumors of an impending ban on stoves fueled by ‘natural gas,’ or methane, currently used in around...
Children’s Antibiotics Shortage, Bat Vocalizations, Life’s Biggest Questions. January 20, 2023, Part 1
Why Are Children’s Antibiotics So Hard To Find Right Now? Mary Warlo has been extremely worried lately. Her baby Calieb, who is six months old, has sickle cell disease.
