NASA Considers Cheaper Ways To Retrieve Mars Samples | How Does A Hula Hoop Stay Up?

Scientists investigated how the shape of the human body makes hula hooping possible—and what hips and a waist have to do with it. And, the decision for how to proceed with NASA's Mars Sample Return Mission will fall to the incoming administration. What Makes A Hula Hoop Stay Up?Hula hooping might appear to be a simple physical activity. But there’s some complex math and physics at play as the hoop goes around your body, and scientists haven’t had a clear understanding of those hidden forces—until now. A team of mathematicians at New York University recently published research into the science of hula hooping in the Proceedings of the National Academy of Sciences. Flora Lichtman is joined by Olivia Pomerenk, a PhD candidate in mathematics at New York University, and a coauthor of that paper. She talks with Flora about why the motion of hula hooping prevents the hoop from falling down and which body types make for the best hooper. NASA Considers Cheaper, Faster Ways To Retrieve Mars SamplesNASA’s Mars Sample Return mission is an ambitious project that aims to use the Perseverance rover to collect Martian rocks, sand, and even gulps of Martian air. Then, through a complicated handoff between different spacecraft, it would ferry those samples to Earth. A 2023 assessment found that the original plan to retrieve the samples would be much more expensive, and take much longer, than initially expected. This week, NASA announced two options for how to cut costs and bring the samples to Earth by the late 2030s. But the agency did not solidify a plan, leaving it to the next administration to sort out around 18 months from now. Is the project on the rocks? To get up to speed on the mission, Flora Lichtman talks with Dr. Jim Bell, professor of earth and space exploration at Arizona State University, and distinguished visiting scientist at NASA’s Jet Propulsion Laboratory.

A Horn Of Potato Plenty | Adding Marbling To Fake Meat For An Extra-Realistic Bite

Just in time for Thanksgiving, a potato researcher explains potato varieties, potato nutrition, and some tubular tuber facts. And, irregular, fatty marbling gives meat a unique texture. Recreating that in plant-based products isn’t easy. A Horn Of Potato PlentyThe potato is a versatile vegetable—baked, roasted, fried, mashed—it can bring something to just about any menu. But, how exactly do these tasty tubers end up on our tables? We’ll give you a crash course in potato science, including how potatoes are grown (hint: not from seeds!) and what scientists look for when they develop new potato varieties. SciFri producer Kathleen Davis talks with Dr. Rhett Spear, assistant professor in the Plant Sciences Department at the University of Idaho. Adding Marbling To Fake Meat For That Extra-Realistic BitePlant-based meat products have evolved over the past few decades. You can find them in many forms, like sausages, deli meats, and faux chicken nuggets. During the holiday season, no plant-based meat is more famous than the Tofurky Roast, a round imitation turkey. Despite improvements in flavor for plant-based meat products, there are still lots of challenges to getting fake meats to mimic their real counterparts. One tough one is textural: instilling a marbling effect. This is the effect of irregular fat deposits, which occur naturally in animal meat. Plant-based meat has a uniform texture by design. Because each product is processed to be a certain way, the randomness and irregularity of fat pockets is taken out of the equation. But some food scientists are working on adding more of this meaty texture to plant-based meat. Joining guest host Kathleen Davis to discuss the challenges and possibilities for the next stage of plant-based meat is Dr. David Julian McClements, distinguished professor in food science at the University of Massachusetts Amherst.

SpaceX’s Starship Completes In-Orbit Engine Test | Resuscitating Shipwrecked Rye Seeds

This was the sixth test launch of the Starship vehicle, which could eventually carry humans and cargo to the moon. It was extremely loud. Also, divers have recovered seeds of a long-lost rye variety from a 146-year-old shipwreck in Lake Huron. Scientists hope to bring it back to life. SpaceX’s Starship Completes In-Orbit Engine TestOn Tuesday, the rocket company SpaceX conducted another test flight of its Starship spacecraft. In the uncrewed mission, the sixth test of the system, the company was seeking to test its ability to restart the Starship engines while in orbit, a function that’s necessary for in-space maneuvering. The rocket did launch successfully, and the engine test worked. However, at the last minute the company elected not to try to repeat an October maneuver in which it caught a returning SuperHeavy rocket booster at the launch tower, citing safety concerns. SciFri’s Charles Bergquist joins guest host Kathleen Davis to talk about the launch, and related research into the tremendous sound created by the system’s launch and reentry. They also discuss other stories from the week in science, including the discovery of a saber-toothed kitten in Siberian permafrost, efforts to use light to help destroy PFAS chemicals, a company using Pokemon Go game data to train an AI, and more. Michigan-Based Team To Resuscitate Shipwrecked Rye SeedsIn 1878, a wooden schooner named the James R. Bentley set sail from Chicago to Buffalo, New York. But strong winds and rough waters damaged the ship, and it sank to the bottom of Lake Huron. The crew was saved, but the ship’s cargo—a large shipment of rye—sank with it. In the years since the shipwreck, that particular variety of rye has faded out of existence. Now, almost 150 years later, a Michigan-based team is trying to bring the long-lost rye back to life. They dove to the shipwreck, retrieved a tube full of seeds, and are planning to use gene technology to recreate the rye variety. Their goal is to encourage farmers to grow it, so that distillers can use it to make whiskey. SciFri producer Kathleen Davis talks with Dr. Eric Olson, professor of wheat breeding and genetics at Michigan State University, and Chad Munger, founder and CEO of Mammoth Distilling.

How Lucy Runs On A Virtual Treadmill | Comparing DeepSeek’s AI To Other Models

Scientists determined that Lucy, a human ancestor from 3.2 million years ago, couldn’t have beaten modern humans in a foot race. Also, the Chinese AI company DeepSeek startled industry observers with an efficient new system. But how does it compare with the leading tech? How Lucy, Our Famous Ancestor, Runs On A Virtual TreadmillLucy is one of the most famous fossils—an Australopithecus afarensis who lived about 3.2 million years ago. Her skeleton is about 40% complete, and has been studied since its discovery in 1974. In a quest to learn more about what Lucy’s life may have looked like, scientists estimated what her leg and pelvic muscles were like based on her skeleton. They then put her on a treadmill—virtually, of course. The findings? Lucy was likely not a natural runner, and the modern human body evolved for improved running performance. Host Flora Lichtman talks to Producer Kathleen Davis about these findings, and other news of the week. Flora also speaks to Anil Oza, a Sharon Begley Science Reporting Fellow at STAT and MIT, about the latest news on the Trump administration taking down scientific data from the Centers for Disease Control website for mentioning topics like gender, DEI and accessibility. They also discuss the National Institutes of Health resuming grant reviews after two weeks of restrictions imposed by the president. How DeepSeek’s AI Compares To Established ModelsThe Chinese company DeepSeek recently startled AI industry observers with its DeepSeek-R1 artificial intelligence model, which performed as well or better than leading systems at a lower cost. The DeepSeek product apparently requires less human input to train, and less energy in parts of its processing—though experts said it remained to be seen if the new model would actually consume less energy overall. Will Douglas Heaven, senior editor for AI at MIT Technology Review, joins Host Ira Flatow to explain the ins and outs of the new DeepSeek systems, how they compare to existing AI products, and what might lie ahead in the field of artificial intelligence.

Trump Administration Cancels Meetings, Freezes Hiring At NIH | What Is A Meme Coin?

Researchers at the National Institutes of Health say the move has sent fear and confusion throughout the agency. Plus, what's the technology behind meme coins? Trump Administration Cancels Meetings, Freezes Hiring At NIHThis was President Trump’s first week back in the Oval Office. Along with issuing a flurry of executive orders, his administration has imposed a range of restrictions on the National Institutes of Health, affecting meetings, travel, hiring, funding, and communications. Scientists expressed alarm about what this could mean for ongoing research, with no clear timeline for if or when the freeze would be lifted. Flora Lichtman is joined by Casey Crownhart, climate editor at the MIT Technology Review, to catch up on this and other big science stories of the week, including what’s coming next this year for nuclear power, why a record amount of snow fell in the Southeast this week, and new research on the surprisingly complex biology of a manta ray tail. What Exactly Is A Meme Coin And How Does It Work?A few days before President Trump’s inauguration, he hosted a “crypto ball” in Washington, D.C. That night, he unveiled his very own meme coin—a kind of digital asset that has gained a reputation for facilitating scams. Soon after, first lady Melania Trump also launched her own meme coin. After its launch, Trump’s coin’s market capitalization reached billions of dollars. This isn’t the first time meme coins have gotten a lot of attention—you might remember Elon Musk joked about another one called Dogecoin on SNL in 2021—but it is the first time that this technology has been used by a sitting president. So what exactly is a meme coin anyway? How does the blockchain play into all this? And how might a president use it differently than an internet celebrity? To find out more, Flora Lichtman talks with Liz Lopatto, a senior writer at The Verge who covers cryptocurrency and business, about how this market started, how Trump could use meme coins, and where the crypto market could go next.

At COP29, The World’s Top Polluters Are No-Shows | Walking Pneumonia Is Spiking

Leaders from the top-polluting countries, like the US and China, aren’t showing up to the UN’s big climate conference in Azerbaijan. And, walking pneumonia typically affects school-age kids, but the CDC reports a rise in cases in children aged 2-4. At COP29, The World’s Top Polluters Are No-ShowsThe United Nations’ annual international climate conference, COP29, got underway this week in Baku, Azerbaijan. Leaders from around the world come together at this conference to hammer out deals between nations to lower emissions and coordinate climate change-related financial efforts. And a big focus this year was to negotiate a deal for wealthier countries to financially compensate developing nations who’ve experienced climate-change related damage. The only problem is that world leaders from the top-polluting countries, like the US and China, aren’t even showing up. Ira Flatow is joined by Umair Irfan, senior correspondent at Vox, to catch up on this and other science stories of the week, including new data on rising alcohol consumption, why Voyager 2 got an inaccurate snapshot of Uranus in the 1980s, and why the world’s largest organism might also be its oldest. Walking Pneumonia Is Spiking. Here’s How To Stay SafeLast month, the Centers for Disease Control and Prevention put out a report outlining a significant spike in Mycoplasma pneumoniae infections, better known as walking pneumonia. This respiratory illness is caused by bacteria spread through respiratory droplets, and symptoms usually mimic the common cold. It’s pretty common, with about 2 million infections happening each year, mostly in school-age kids. This year’s spike, which started in the spring, is a little different: There’s been a significant increase in kids aged 2 to 4 and it is now the new leading cause of pneumonia for that group. Dr. Preeti Sharma, pediatric pulmonologist at Children’s Heath in Dallas, knows what it’s like to have a child with mycoplasma pneumonia. Her daughter came home with the illness in the spring. What she thought was a typical cold turned into a deep and lingering cough: a telltale sign of walking pneumonia. Dr. Sharma, who is also an associate professor at UT Southwestern, joins Ira Flatow to discuss this year’s Mycoplasma pneumoniae spike, the best treatments, and how to keep your family healthy this holiday season.

The History Of Teeth, From Ancient Fish To Humans

Your teeth don’t just chew your food—they connect you to the deepest of deep history on Earth. Teeth have existed, in some form, for half a billion years, making them more than 250 million years older than dinosaurs. They came before the evolution of warm bloodedness, eggs, and even limbs. From that very first set of chompers emerged a bewildering and diverse group of teeth, including narwhal tusks, sharks’ pearly teeth, snake fangs, and, of course, ours. Now teeth are the subject of a new book called Bite: An Incisive History of Teeth from Hagfish to Humans. Guest host Maggie Koerth talks with zoologist and author Dr. Bill Schutt about how teeth evolved, why they’re so neat, and what we can learn from studying them. Read an excerpt of Bite: An Incisive History of Teeth from Hagfish to Humans. Transcripts for each segment will be available after the show airs on sciencefriday.com. Subscribe to this podcast.

January 6th Was Not a Secret Attack

Micah Loewinger, a reporter for On the Media, began monitoring militia conversations in early 2020. The potential for violence was immediately clear. And so when they staged an insurrection at the Capitol on January 6, 2021, Micah was listening and recording. But when his reporting became part of the FBI’s case against the Oath Keepers, it raised difficult questions about his role as a journalist. Tell us what you think.
