2 Private Lunar Landers | Cervical Cancer Deaths Plummet, Experts Credit HPV Vaccine

The SpaceX rocket carries lunar landers from companies based in Texas and Japan. They could arrive at the moon in the coming months. HPV can cause a variety of cancers, including cervical. New mortality data for women under 25 point to the success of the HPV vaccine. Rocket Launches With Lunar Landers From 2 Private Companies ----------------------------------------------------------- On Wednesday, a SpaceX rocket launched carrying payloads from two separate private companies hoping to achieve lunar landings. [The pair of landers] (https://www.sciencefriday.com/segments/spacex-launch-commercial-lunar-landers/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) —one from Japanese company ispace, and one from Texas-based Firefly Aerospace—will take months to reach the moon. Firefly’s lander is scheduled to arrive first, in March, with ispace’s lander planned for a touchdown in late May or early June. Another SpaceX launch on Thursday, a test flight of the company’s Starship system, had mixed results. The booster returned to earth and was successfully “caught,” but the spacecraft [exploded] (https://www.sciencefriday.com/segments/spacex-launch-commercial-lunar-landers/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) over the Caribbean shortly after launch. That explosion is under investigation. Jason Dinh, climate editor at Atmos in Washington, D.C., joins Ira to talk about the Wednesday launch and plans for private lunar exploration. They also discuss other stories from the week in science, including the ban of Red Dye #3 an AI approach to snake antivenom, and a study predicting a rise in US dementia cases by 2060. As Cervical Cancer Deaths Plummet, Experts Credit HPV Vaccine ------------------------------------------------------------- In 2006, a vaccine for the human papillomavirus (HPV) became widely available to adolescents. HPV is the most common sexually transmitted infection, and it can cause cancers of the mouth, throat, and sexual organs. It’s also the cause of nearly every case of cervical cancer. Now, almost 20 years after the HPV vaccine was introduced, [a study] (https://www.sciencefriday.com/segments/hpv-vaccine-lowers-cervical-cancer-deaths/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) published in JAMA noted a 62% drop in deaths due to cervical cancer in women under 25 in the US: from 50 or 60 deaths per year to 13. This follows earlier research that noted a decrease in cervical precancer and cancer since the introduction of the vaccine. With HPV vaccine uptake at about 60% for adolescents aged 13-15, a higher uptake could virtually eliminate cervical cancer, experts say. However, childhood vaccination rates have dwindled since the start of the COVID-19 pandemic, sparking concerns about the spread of preventable disease. Joining Flora Lichtman to talk about this latest study is lead author Dr. Ashish Deshmukh, professor of public health sciences and co-leader of the Cancer Prevention and Control Program at the Medical University of South Carolina in Charleston, South Carolina. Transcripts for each segment will be available after the show airs on [sciencefriday.com.] (https://www.sciencefriday.com/episodes/january-17-2025/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) [Subscribe to this podcast.] (https://pod.link/73329284) Plus, to stay updated on all things science, [sign up for Science Friday's newsletters] (https://www.sciencefriday.com/newsletters/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . ...

‘Artificial General Intelligence’ Is Apparently Coming. What Is It?

For years, artificial intelligence companies have heralded the coming of [artificial general intelligence] (https://www.sciencefriday.com/segments/what-is-agi/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , or AGI. OpenAI, which makes the chatbot ChatGPT, has said that their founding goal was to build AGI that “benefits all of humanity” and “gives everyone incredible new capabilities.” Google DeepMind cofounder Dr. Demis Hassabis has described AGI as a system that “should be able to do pretty much [any cognitive task that humans can do] (https://www.sciencefriday.com/segments/what-is-agi/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) .” Last year, OpenAI CEO Sam Altman said AGI will arrive sooner than expected, but that it would matter much less than people think. And earlier this week, Altman said in a blog post that the company knows how to build AGI as we’ve “traditionally understood it.” But what is artificial general intelligence supposed to be, anyway? Ira Flatow is joined by Dr. Melanie Mitchell, a professor at Santa Fe University who studies cognition in artificial intelligence and machine systems. They talk about the history of AGI, how biologists study animal intelligence, and [what could come next in the field.] (https://www.sciencefriday.com/segments/what-is-agi/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) Transcripts for each segment will be available after the show airs on [ sciencefriday.com.] (https://www.sciencefriday.com/episodes/january-10-2025//?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) [Subscribe to this podcast.] (https://pod.link/73329284) Plus, to stay updated on all things science, [sign up for Science Friday's newsletters] (https://www.sciencefriday.com/newsletters/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . ...

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] (https://www.sciencefriday.com/segments/hula-hoop-body-type-physics/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) 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] (https://www.sciencefriday.com/segments/hula-hoop-body-type-physics/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) 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.] (https://www.sciencefriday.com/segments/hula-hoop-body-type-physics/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) NASA Considers Cheaper, Faster Ways To Retrieve Mars Samples ------------------------------------------------------------ NASA’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.] (https://www.sciencefriday.com/segments/nasa-mars-sample-return-mission-plan-trump/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) 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] (https://www.sciencefriday.com/segments/nasa-mars-sample-return-mission-plan-trump/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) 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?] (https://www.sciencefriday.com/segments/nasa-mars-sample-return-mission-plan-trump/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) 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.

Surgeon General Highlights Link Between Alcohol And Cancer

Alcohol poses many risks to our health, including liver damage and driving under the influence. Now, U.S. Surgeon General Dr. Vivek Murthy has highlighted another risk of drinking alcohol: cancer. In his [latest advisory] (https://www.sciencefriday.com/segments/surgeon-general-advisory-on-alcohol-and-cancer/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , Murthy detailed the growing body of research showing that drinking alcohol can increase the risk of at least seven types of cancers, those of the mouth, throat, voice box, esophagus, breast, liver, and colon. He’s also recommended adding [a warning] (https://www.sciencefriday.com/segments/surgeon-general-advisory-on-alcohol-and-cancer/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) to alcohol outlining the connection between alcohol use and cancer.

First U.S. Bird Flu Death Raises Concerns About Preparedness

On January 6, the U.S. reported its [first human death] (https://www.sciencefriday.com/segments/bird-flu-death-united-states-prep/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) from the bird flu. According to the CDC, more than 60 people were diagnosed with bird flu in the US last year, up from just one case in 2022. If you look at global cases over the last two decades, of the nearly 900 reported cases in people, roughly half the patients died. H5N1 avian influenza has been circulating in birds—and even some mammals—for years. But in the spring of 2024, the virus turned up in [dairy cattle] (https://www.sciencefriday.com/segments/bird-flu-death-united-states-prep/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . Since then, over 900 herds have been affected, according to the CDC. This might bring back memories from early in the COVID-19 pandemic—but is that the right way to think about this? Should we be concerned? And what steps should we be taking? To unpack this, host Flora Lichtman talks with Dr. Seema Lakdawala, co-director for the Center for Transmission of Airborne Pathogens and associate professor studying influenza viruses at Emory University in Atlanta, Georgia; and Dr. Richard Webby, director of the World Health Organization Collaborating Centre for Studies on the Ecology of Influenza in Animals and Birds and virologist at St. Jude’s Children’s Research Hospital in Memphis, Tennessee.

Meet Flora Lichtman | Los Angeles Wildfires Stoked By Santa Ana Winds

After her SciFri internship 20 years ago, Flora went on to become a beloved science journalist, video producer, and podcaster. Now she’s back! Also, several different fires are causing extreme damage in the Los Angeles area. Strong Santa Ana winds are one factor behind their rapid spread. Science Friday Now Has Two Hosts: Meet Flora Lichtman! ------------------------------------------------------ Big news! Science Friday now has two hosts—Ira Flatow, the program’s founder, and veteran science journalist [Flora Lichtman] (https://www.sciencefriday.com/segments/flora-lichtman-science-friday-host/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . Going forward, you’ll hear both of them regularly on the air and on our podcast.  Flora joins Ira to introduce herself and talk about her background, from her start as an intern at Science Friday 20 years ago to her role as a video producer, then a writer for Bill Nye, and as creator of the podcast “Every Little Thing.” Los Angeles Wildfires Burn For Days, Stoked By Santa Ana Winds -------------------------------------------------------------- This week, the Los Angeles area has been battered by at least five separate [wildfires] (https://www.sciencefriday.com/segments/los-angeles-wildfires-santa-ana-winds/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . Tens of thousands of acres have burned, and thousands of people have been forced to flee their homes. Fire experts had warned on January 2 that conditions were ideal for wildfires in parts of Southern California. One factor that has helped these fires spread rapidly? Unusually strong [Santa Ana winds.] (https://www.sciencefriday.com/segments/los-angeles-wildfires-santa-ana-winds/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) On the other side of the country, [Winter Storm Blair] (https://www.sciencefriday.com/segments/los-angeles-wildfires-santa-ana-winds/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) has caused freezing temperatures and up to a foot of snow across the Midwest and up into the East Coast, putting more than 60 million people under weather alerts.

What Lichen Tell Us About Ecology, Air Quality, And More

Last October, Ira Flatow took a trip to the World Forestry Center in Portland, Oregon, for [a daylong exploration of lichen] (https://www.sciencefriday.com/segments/lichen-ecology-air-quality-oregon-event/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) —the fuzzy growths often found on trees, roofs, and gravestones. Ira sat down in front of a sold-out room with Dr. Hannah Prather, postdoctoral researcher and visiting assistant professor of biology at Reed College, and Dr. Jesse Miller, lead botanist for the Washington Natural Heritage Program. From their crucial role in ecosystems as [indicators of air quality] (https://www.sciencefriday.com/segments/lichen-ecology-air-quality-oregon-event/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) to their striking colors and forms, we’ve really taken a lichen to these amazing organisms.

Biologists Call For A Halt To ‘Mirror Life’ Research

You’re probably familiar with the concept of handedness—a glove made for your left hand looks basically like the one for your right hand, but won’t fit—it’s a mirror image. Many of life’s important molecules, including proteins and DNA, are chiral, meaning they can exist in either a left-handed or a right-handed form. But on Earth, nature only uses one version or the other in living organisms. Your proteins, for example, are all the left-handed version, while [your DNA is all right-handed] (https://www.sciencefriday.com/segments/mirror-life-risks-molecular-chirality/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . With advances in synthetic biology, it could be possible to build an artificial organism that flips that shape, having right-handed proteins and left-handed DNA. Writing in the journal Science, an international group of researchers recently cautioned against anyone trying to create that sort of [so-called mirror life] (https://www.sciencefriday.com/segments/mirror-life-risks-molecular-chirality/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , saying that it poses the threat of “unprecedented and irreversible harm” to human health and global ecosystems. Dr. Drew Endy, a synthetic biology researcher at Stanford University and one of the authors of that warning, joins Ira to discuss the concept of mirror life and why a group of researchers felt compelled to [call for a halt to mirror life experiments] (https://www.sciencefriday.com/segments/mirror-life-risks-molecular-chirality/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) .

The Breakthrough Technologies To Watch In 2025

Each year, the journalists at the MIT Technology Review publish a list of [10 breakthrough technologies] (https://www.sciencefriday.com/segments/breakthrough-technologies-to-watch-in-2025/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) : these are things poised to hit a tipping point, and potentially change the way the world works.  Unsurprisingly, artificial intelligence remains a big breakthrough. While 2024 was the year of large learning models, small learning models top Technology Review’s list this year. These [smaller models] (https://www.sciencefriday.com/segments/breakthrough-technologies-to-watch-in-2025/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) are more accessible, efficient, and could be better for the climate than their larger counterparts.  Also on the list is generative AI search, which is already implemented by Google with its Gemini language model. A new HIV medication called Lenacapavir, which has been shown to be incredibly effective in trials, is also on the list, along with cleaner, [alternative jet fuels] (https://www.sciencefriday.com/segments/breakthrough-technologies-to-watch-in-2025/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) .

Meet Leaders Of 3 Local Conservation Projects | Preserving ‘Space Junk’ Left On Mars

What makes three very different conservation projects so successful? These experts say it’s getting the community involved. And, archaeologists make a case for tracking and preserving artifacts left on Mars to chronicle humans’ first attempts at interplanetary exploration. Meet 3 Leaders Addressing Local Conservation Problems ----------------------------------------------------- While 2024 saw a lot of governments and institutions falling short on climate goals, there were also smaller, localized efforts [making a big difference for the environment] (https://www.sciencefriday.com/segments/tiny-nature-triumphs-local-conservation/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . To understand more about the creative ways that people are protecting nature, Science Friday began a newsletter series called [“Tiny Nature Triumphs.”] (https://www.sciencefriday.com/segments/tiny-nature-triumphs-local-conservation/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) It highlights small conservation projects that have helped scientists and communities alike—and inspired people to get involved in solutions in their own backyard. SciFri Digital Producer Emma Gometz sits down with [leaders on three projects] (https://www.sciencefriday.com/segments/tiny-nature-triumphs-local-conservation/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) featured in “Tiny Nature Triumphs”—Claire Lane, an urban ecologist and leader on the Hamilton County Invasive Species Trade In Program; Jake Rose, co-founder of Chronolog; and Shaun Preston, yardmaster at Camp Small. They discuss how their programs address local conservation problems, and how to get involved. A New Argument For Preserving ‘Space Junk’ Left On Mars ------------------------------------------------------- Over the past 60 years or so of space exploration, humans have left some things behind: bits of satellites, moon buggies, Mars rovers, even human excrement. It’s all part of the [countless bits of human-made material] (https://www.sciencefriday.com/segments/mars-space-junk-archaeology/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) that some people have dubbed “space junk.” But what if, many, many years from now, archeologists wanted to trace the chronology of space exploration by examining the items we left in our wake? A new paper in the journal Nature Astronomy argues just this, that [artifacts should be considered heritage] (https://www.sciencefriday.com/segments/mars-space-junk-archaeology/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , rather than trash. Lead author Dr. Justin Holcomb, assistant research professor at the University of Kansas, joins Ira to discuss [shifting our mindset on “space junk.”] (https://www.sciencefriday.com/segments/mars-space-junk-archaeology/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) Transcripts for each segment will be available after the show airs on [sciencefriday.com.] (https://www.sciencefriday.com/episodes/december-20-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) [Subscribe to this podcast.] (https://pod.link/73329284) Plus, to stay updated on all things science, [sign up for Science Friday's newsletters] (https://www.sciencefriday.com/newsletters/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . ...

The Top Dino Discoveries Of 2024 | Can Spiking Eggnog Kill Bacteria From Raw Eggs?

To wrap up 2024, science writer Riley Black shares her favorite paleontology discoveries of the year. And, if treated properly, even old-fashioned eggnog made with cream and raw eggs can be a safe holiday beverage. The Most Exciting Dino Discoveries Of 2024 ------------------------------------------ December is, traditionally, a time to reflect on the events of the past year—including dinosaur discoveries. In 2024, researchers learned more about T. rex and the [spiky tails of stegosaurs] (https://www.sciencefriday.com/segments/best-dinosaur-discoveries-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) as well as how dinosaurs evolved, lived, and more. For Smithsonian Magazine, dinosaur enthusiast and science writer Riley Black rounded up her [top dino discoveries of the year] (https://www.sciencefriday.com/segments/best-dinosaur-discoveries-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . She talks with Ira Flatow about the most exciting paleontology news of 2024. Can Spiking Eggnog Kill Bacteria From The Raw Eggs? --------------------------------------------------- It’s a question that occasionally comes up over the course of a holiday celebration, at least in certain circles: whether or not the alcohol in old-fashioned eggnog made with real cream and raw eggs can [protect against foodborne pathogens] (https://www.sciencefriday.com/segments/spiked-eggnog-recipe-science/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) such as salmonella. Around 15 years ago, Science Friday investigated, enlisting the help of a lab at Rockefeller University that has a tradition of mixing up a big batch of old-fashioned eggnog around Thanksgiving, then serving it weeks later at a lab holiday party. The researchers kindly conducted a controlled study in which they deliberately [spiked samples of their potent eggnog with salmonella] (https://www.sciencefriday.com/segments/spiked-eggnog-recipe-science/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , then followed the mixture’s bacterial status over the course of several weeks. Science Friday’s Charles Bergquist checks in with Dr. Vincent Fischetti, a bacteriologist at Rockefeller, to see if there have been any advances in [the field of eggnogology] (https://www.sciencefriday.com/segments/spiked-eggnog-recipe-science/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) .

Parker Solar Probe Will Make Closest-Ever Approach To Sun

On December 24, NASA’s [Parker Solar Probe] (https://www.sciencefriday.com/segments/nasa-parker-solar-probe/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) will make the closest-ever approach to the sun by a spacecraft. Parker has made more than 20 close approaches to the sun before, but this one will swoop in even closer than 3.8 million miles away from the sun’s surface. Since the probe was launched back in 2018, it’s helped scientists better understand our star and unravel mysteries about [solar wind] (https://www.sciencefriday.com/segments/nasa-parker-solar-probe/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , high-energy solar particles, the sun’s corona and more. Scientists hope that this upcoming approach will reveal even more about the star at the center of our solar system. Ira Flatow talks with Dr. Nour Rawafi, project scientist for NASA’s Parker Solar Probe mission and astrophysicist at the Johns Hopkins Applied Physics Laboratory in Maryland. They discuss the goal of this close approach, how the spacecraft will stand the heat, and what else there is to learn about our sun.

If ‘Interstellar’ Were Made Today, What Would Be Different?

For its 10th anniversary, the science advisor for “Interstellar” discusses the film’s impact and how new information about gravitational waves could have changed it. The science fiction film “ [Interstellar] (https://www.sciencefriday.com/segments/10-year-anniversary-interstellar/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) ” turns 10 years old this month. For many of us, it was our first encounter with some pretty advanced astrophysics, taking sci-fi concepts like wormholes and time warping, and backing them up with actual science. Now, we’re revisiting the impact that movie’s science had on pop culture, and how astrophysics has advanced in the past decade. If it were made today, what would be different? Ira Flatow sits down with “Interstellar” science advisor Dr. Kip Thorne, a professor of theoretical physics at the California Institute of Technology. Since the film’s release, he has won a Nobel Prize for his contributions to the detection of gravitational waves generated from black holes. They discuss how the film inspired people to pursue scientific careers and how recent astrophysics discoveries, like [gravitational waves] (https://www.sciencefriday.com/segments/10-year-anniversary-interstellar/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , could’ve made it into the movie.

Farewell, Murder Hornet | What FAA Regulations Tell Us About Mysterious Drone Sightings

Officials say the invasive Asian giant hornet, with its menacing nickname, has been eradicated from the United States. Also, with drone sightings in the news, we take a look at the current laws and regulations around hobby and commercial drone operation. Farewell, Murder Hornet, We Hardly Knew You ------------------------------------------- Over the past few years many words have been written about an invasive insect known casually as the “ [murder hornet] (https://www.sciencefriday.com/segments/asian-giant-hornet-eradication/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) ”—more formally, the Asian giant hornet, or northern giant hornet. But this week, the USDA and the Washington State Department of Agriculture announced that the insect has been [eradicated] (https://www.sciencefriday.com/segments/asian-giant-hornet-eradication/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) in the United States. Our long national nightmare is over. Science journalist Maggie Koerth joins Ira to talk about the entomology news, plus other stories from the week in science, including debate over how viruses should be named, the complicated relationship between science and law in the courtroom, and work tracing health signs—through earwax. What FAA Regulations Tell Us About Mysterious Drone Sightings ------------------------------------------------------------- It’s been all over the news the last few weeks: a slew of [drone sightings] (https://www.sciencefriday.com/segments/drone-sightings-faa/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) in New Jersey and elsewhere on the East Coast, starting in mid-November. Federal authorities and President Biden have said that these drones don’t appear to be a threat to public safety, and that the sightings have been a mix of legal drones, airplanes, and helicopters. But questions and concerns remain, particularly among people who live in these areas. And just this week, the Federal Aviation Authority (FAA) [banned] (https://www.sciencefriday.com/segments/drone-sightings-faa/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) most drones from flying over nearly two dozen New Jersey towns. Dr. Missy Cummings, professor and director of George Mason University’s Autonomy and Robotics Center in Fairfax, Virginia, has worked on drone technology extensively over the years. She agrees with what federal authorities have said: that these drones sightings are likely legal drones and aircraft, with some prankster drone owners mixed in.

How Blind Women In India Detect Early Breast Cancer | Web-Slinging Silk Becomes Real

A program trains women as tactile medical examiners to identify tumors before they show up on imaging scans. And, in a materials science discovery, scientists made a liquid silk solution that hardens and picks up objects—not unlike Spider-Man’s web. How Blind Women In India Are Detecting Early Breast Cancer ---------------------------------------------------------- Breast cancer is the second most common cancer worldwide, just behind lung cancer. And the earlier a breast tumor is found, the more likely it is that the person survives their diagnosis. An international program called Discovering Hands [trains blind women] (https://www.sciencefriday.com/segments/blind-women-in-india-detect-breast-cancer/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) to detect even the smallest lumps and bumps through breast exams. The idea is to leverage the blind examiners’ sense of touch, which may be more acute than sighted people’s, to feel for breast abnormalities and, hopefully, [catch cancer in an early stage] (https://www.sciencefriday.com/segments/blind-women-in-india-detect-breast-cancer/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . Discovering Hands has a cohort in India, a country where only around one in every two people diagnosed with breast cancer survive, and imaging equipment can be expensive or hard to come by. SciFri producer Rasha Aridi talks with science journalist Kamala Thiagarajan, who reported on [Discovering Hands’ program in India] (https://www.sciencefriday.com/segments/blind-women-in-india-detect-breast-cancer/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) for NPR’s global health blog, Goats and Soda. Accidental Breakthrough Makes Web-Slinging Silk A Reality --------------------------------------------------------- We’re all familiar with Spider-Man—the red-suited hero who swings through New York using spider silk that shoots from his hands. While Peter Parker has a radioactive spider to thank for his shooting webs, scientists at Tufts University have made their own version of [liquid silk that solidifies] (https://www.sciencefriday.com/segments/spiderman-silk-discovery-tufts-silklab/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) and can pick up objects. This discovery was made accidentally, says biomedical engineer Dr. Marco Lo Presti of the Tufts University Silklab. Lo Presti found that combining silk from a silkworm with dopamine and acetone made the silk change [from a flexible liquid to a hardened fiber] (https://www.sciencefriday.com/segments/spiderman-silk-discovery-tufts-silklab/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) that attaches to objects. Lo Presti joins guest host Kathleen Davis to talk about the possibilities of liquid silk adhesives, and the advancements he’d like to see to make the technology better.

8.5 Hours Of Daily Sitting Linked To Higher BMI And Cholesterol

Sitting is a big part of modern life. Many people work at a desk all day, have long commutes, or at least enjoy some time relaxing on the couch at the end of the day. But sitting has gained a reputation as being bad for us—with some going so far as to call it “the new smoking.” A recent study in the journal PLOS One sheds more light on just [how much sitting is too much] (https://www.sciencefriday.com/segments/sitting-and-health-bmi-cholesterol/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , using a cohort of more than 1,000 young adults, including 730 twins. The results showed that sitting for more than about [eight and a half hours per day] (https://www.sciencefriday.com/segments/sitting-and-health-bmi-cholesterol/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) is linked to a higher total cholesterol and body mass index than sitting for less than that amount of time. But there’s good news: [30 minutes of vigorous exercise] (https://www.sciencefriday.com/segments/sitting-and-health-bmi-cholesterol/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) per day may counter the negative effects that come from long days of sitting. Joining guest host Kathleen Davis to discuss the findings are two of the study authors: Dr. Chandra Reynolds, professor in the Institute of Behavioral Genetics at the University of Colorado, Boulder; and Ryan Bruellman, PhD candidate in genetics, genomics, and bioinformatics at the University of California, Riverside.

The Accidental Discovery That Gave Us ‘Forever Chemicals’ | A Pregnancy Play Inspired By Mushroom Re...

The Accidental Discovery That Gave Us ‘Forever Chemicals’ --------------------------------------------------------- When it comes to PFAS chemicals—known as “forever chemicals”—we often hear that they’re used in nonstick coatings, flame retardants, and stain repellants. But those examples can hide the truth of just how widespread their use has been in modern life. A new season of the “Hazard NJ” podcast looks at the [origin story of PFAS chemicals] (https://www.sciencefriday.com/segments/forever-chemicals-teflon-new-jersey/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , and the accidental discovery of PTFE—aka Teflon—in a DuPont laboratory in southern New Jersey. “Hazard NJ” host Jordan Gass-Pooré joins guest host Kathleen Davis to talk about the history of PFAS, their effect on the environment and health of New Jersey residents, and work towards cleaning up the PFAS mess. A Play About Pregnancy Inspired By Mushroom Research ---------------------------------------------------- People are finding all sorts of uses for mushrooms these days, but we’re going to focus on two of them: how scientists are using them in robots and how playwrights are using them in theater. A few weeks ago, SciFri producer and host of our “ [Universe of Art] (https://www.sciencefriday.com/universe-of-art/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) ” podcast D Peterschmidt moderated a panel at the [Science In Theater Festival] (https://www.sciencefriday.com/segments/science-in-theater-prengnancy-mushroom-research/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) in Brooklyn, New York. The festival is put on by a company called Transforma Theatre that stages science-inspired plays. Each year, they pair playwrights with scientists to make short plays that explore the research focus of the scientist. Director and playwright Hannah Simms was paired with Dr. Andrew Adamatzky, a professor of unconventional computing, who’s learning how to connect various parts of nature, like mushrooms, to computers, and consulted with Hannah during the writing process. The play, called “ [Fruiting Body,] (https://www.sciencefriday.com/segments/science-in-theater-prengnancy-mushroom-research/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) ” is about a fungal-computing scientist who, while pregnant, creates a fetal heart monitor powered by mycelium, which turns out to be sentient. While the concept is definitely science fiction, it is based on real unconventional mushroom research. D talks with Hannah to learn why she wanted to explore her pregnancy through the lens of mushroom research. They’re also joined by Dr. Anand Mishra, a research associate at Cornell University’s department  of mechanical and aerospace engineering, who explains how he helped build a robot that’s powered by king oyster mushroom mycelium.

How Empire and Environmental Destruction Go Hand-In-Hand

“The Burning Earth” examines over 800 years of history to demonstrate how violence against people and the planet are one and the same. Also, the host of the “Hazard NJ” podcast talks about the origins of PFAS “forever chemicals” and their impact on New Jersey residents. How Empire and Environmental Destruction Go Hand-In-Hand -------------------------------------------------------- A new book called The Burning Earth: A History takes on a massive question: How did we get here? “Here” being this point in environmental history and decades deep into the climate crisis. Over the span of [800 years of history] (https://www.sciencefriday.com/segments/the-burning-earth-a-history/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , the book connects the dots of how the pursuit of empire, environmental destruction, and human migration led us to this moment in time. SciFri producer Kathleen Davis talks with author Dr. Sunil Amrith, a historian at Yale University. They discuss some common threads that run through [human and environmental history] (https://www.sciencefriday.com/segments/the-burning-earth-a-history/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , why peace has to be a part of climate action, and what we can learn from understanding the past.

The Universe Is Expanding Faster Than Expected | Are Food Recalls Actually On The Rise?

The effect, known as the Hubble Tension, has been confirmed by James Webb Space Telescope observations. Also, despite near daily warnings of food recalls, 2024 hasn’t been that different from previous years. The Universe Is Expanding Faster Than Expected ---------------------------------------------- There’s still a lot to be learned about the physics of our universe—and one of the most perplexing ideas is something called the [Hubble Tension] (https://www.sciencefriday.com/segments/universe-expansing-hubble-tension/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . That’s an observation, made around a decade ago, that the universe seems to be expanding faster than it should be according to cosmologists’ understanding of its earliest days. Now, two years of [James Webb Space Telescope observations] (https://www.sciencefriday.com/segments/universe-expansing-hubble-tension/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) of supernovae have confirmed those previous measurements made by the Hubble telescope, meaning that the puzzle isn’t just due to some instrumental error. Casey Crownhart, climate reporter at MIT Technology Review, joins Kathleen Davis to talk about that finding and other stories from the week in science, including a new quantum computing chip from Google, efforts to improve electrical control of prosthetics, proposed new protections for monarch butterflies, and more. Are Food Recalls Actually On The Rise? Not Really. -------------------------------------------------- It feels like there’s been an onslaught of food recalls this year. The Food and Drug Administration and the Department of Agriculture have issued recalls for items like cucumbers and carrots, deli meat and smoked salmon, which have been contaminated with [pathogens like salmonella, E. coli, and listeria.] (https://www.sciencefriday.com/segments/food-recalls-increasing-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) There were just over 1,900 food recalls in the fiscal year ending in October 2024. While that number has been increasing since an initial dip in recalls early in the COVID-19 pandemic, [it’s still lower] (https://www.sciencefriday.com/segments/food-recalls-increasing-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) than the numbers seen in the several years before the pandemic. SciFri producer Kathleen Davis talks with Dr. Byron Chaves, food scientist and professor at the University of Nebraska-Lincoln, about why it feels like there are so many food recalls this year, how a recall happens, and what food safety tips you should know as a consumer.

You Share Your Gut Microbiome With Your Friends

The microbiome, the network of tens of [trillions of microbes] (https://www.sciencefriday.com/segments/you-share-your-gut-microbiome-with-your-friends/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) that live in and on our bodies, helps us digest food and protects us from diseases. And depending on what species of bacteria you have, your microbiome could impact your stress response, decision-making, and how likely you are to develop arthritis and depression. Scientists have known that your microbiome is partially [shaped by your environment] (https://www.sciencefriday.com/segments/you-share-your-gut-microbiome-with-your-friends/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , and the people you spend your time with. But they haven’t had a lot of clarity on how exactly social networks outside of home and family impact our microbiome makeup. To learn more, a team from Yale University mapped the connections among 2,000 people in isolated villages in Honduras and compared their microbiomes to see how exactly their [social closeness impacted their gut bacteria] (https://www.sciencefriday.com/segments/you-share-your-gut-microbiome-with-your-friends/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . And it turns out, we’re more connected to people in our lives than you may think. Their research was published in the journal Nature. Ira Flatow is joined by sociologist and physician Dr. Nicholas Christakis, who directs the Human Nature Lab at Yale University. He studies the biology of human social interactions and was an author on the recent paper. They discuss how the researchers worked with villages in Honduras to gather samples and how they can tell who your friends are, just by looking at your poop.

Marie Curie And The Women Scientists Who Became Her Legacy

When you consider someone’s legacy in science, you might think about their biggest discovery, their list of publications, or their titles, awards, and prizes. But another kind of scientific legacy involves the students and colleagues that passed through a scientist’s orbit over the course of a career. A new book, [The Elements of Marie Curie: How the Glow of Radium Lit a Path for Women in Science] (https://bookshop.org/a/18570/9780802163820) , takes a look at the legacy of Madame Marie Curie, one of the most recognizable names in science history. But instead of looking only at Curie’s own life, author Dava Sobel views her through the lens of some of the [45 women] (https://www.sciencefriday.com/segments/dava-sobel-marie-curie-book/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) who trained in Curie’s lab during her research into radioactivity. Ira Flatow talks with Sobel about her research into Curie’s life, some of the anecdotes from the book, and how she interacted with some of her lab assistants and colleagues.

Protecting Against Poison Exposure This Holiday Season

There are a lot of holiday gatherings at this time of year, and families getting together can mean that kids are in places that don’t normally have a lot of kid visitors. And, as we know, curious kids can get into trouble. Dr. Sing-Yi Feng, a pediatric emergency physician and medical toxicologist with the North Texas Poison Center, joins Ira to talk about some of the [most common toxic exposures] (https://www.sciencefriday.com/segments/protecting-against-poison-exposure-this-holiday-season-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) seen in hospital emergency rooms over the holidays. She stresses that even more than protecting against consumption of poinsettia plants or the cleaning supplies under the sink, households with young kids should be sure to control access to prescription medications, alcohol, and cannabis gummies.

Supreme Court Case On Regulation Of Vapes | Predicting Lithium-Ion Battery Explosions

The Supreme Court hears a case centering on the FDA’s denial of applications for nicotine-based vapes containing flavored liquid seen as addictive for young people. And, damaged lithium-ion batteries can cause deadly explosions. An algorithm could help detect when they’re about to happen. Supreme Court Hears Case On FDA Regulation Of Flavored Vapes ------------------------------------------------------------ On Monday, the US Supreme Court heard arguments in a case that could change the Food and Drug Administration’s power to [regulate nicotine-based vapes] (https://www.sciencefriday.com/segments/supreme-court-flavored-vapes-nicotine/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . It revolves around the FDA’s denial of applications from two vape companies that sell flavored liquids in their products, citing that the liquids presented a danger in [addicting young people] (https://www.sciencefriday.com/segments/supreme-court-flavored-vapes-nicotine/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) to nicotine. But a lower court rejected that denial, saying the agency was inconsistent in its approval process. The decision could impact the FDA’s regulatory power to ban the sale of some of these vapes in the US. Ira Flatow is joined by Rachel Feltman, host of the Popular Science podcast “The Weirdest Thing I Learned This Week,” to talk about the health implications of the case. They also discuss other [top science stories of the week] (https://www.sciencefriday.com/segments/supreme-court-flavored-vapes-nicotine/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) , including why there’s been a large decrease in cervical cancer rates over the past decade, why Venus probably wasn’t able to support ancient life (contradicting some hopeful theories), and new information about when humans might’ve started to wear clothing, thanks to some clues from lice. A Warning For When A Lithium-Ion Battery Is About To Explode ------------------------------------------------------------ Lithium-ion batteries are used in all sorts of electronics, like smart phones, laptops, and e-bikes. That’s because they can store a lot of energy in a small package. Unfortunately, this also means that when a battery is damaged, there’s a lot of energy to expel, which can lead to [explosions and fires] (https://www.sciencefriday.com/segments/lithium-ion-battery-explosion-fire-warning-ai/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . While there are no national statistics available, in New York City alone, there have been 733 fires started by lithium-ion batteries since 2019, which [killed 29 people and injured 442] (https://www.sciencefriday.com/segments/lithium-ion-battery-explosion-fire-warning-ai/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . Most of these fires are a result of e-bike or scooter batteries catching fire. Now, researchers have trained AI algorithms to be able to better [predict when a lithium-ion battery is about to explode] (https://www.sciencefriday.com/segments/lithium-ion-battery-explosion-fire-warning-ai/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . The battery makes a hissing sound two minutes before an explosion. Ira talks with two researchers at the National Institute of Standards and Technology about their work on the subject: Dr. Andy Tam, mechanical engineer in the Fire Research Division, and Dr. Anthony Putorti, fire protection engineer and leader of the Firefighting Technology Group.

A Theatrical Tribute To Unexpected Science

The Ig Nobel awards are a salute to achievements that, in the words of the organizers, “make people laugh, then think.”  Each year, the editors of the science humor magazine Annals of Improbable Research choose 10 lucky(?) winners who have unusual achievements in science, medicine, and other fields. [This year’s awards] (https://www.sciencefriday.com/segments/ig-nobel-awards-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) were presented in a theatrical extravaganza in an MIT lecture hall in September. They included awards for studying coin flipping (including hundreds of thousands of real coin flips), the movements of a dead trout, and an opera about Murphy’s Law. In a Science Friday holiday tradition, Ira hosts an hour of highlights from the ceremony. Transcripts for each segment will be available after the show airs on [sciencefriday.com.] (https://www.sciencefriday.com/episodes/november-29-2024/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) [Subscribe to this podcast.] (https://pod.link/73329284) Plus, to stay updated on all things science, [sign up for Science Friday's newsletters] (https://www.sciencefriday.com/newsletters/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) . ...
