We’re one month away from the presidential election. The campaigns are in high gear, trying to get their messages out, and hoping that those messages will be enough to motivate voters to both go to the polls—and to vote in their favor. But just how solid are people’s political opinions at this point? Can anyone be swayed at this point by another debate, campaign ad, or stump speech talking point? And how do campaigns judge the mood of the electorate to better position their messages? Dr. Jon Krosnick, director of the Political Psychology Research Group at Stanford University, joins Ira Flatow to talk about political decision-making, the ways campaigns can influence voters, the effectiveness of polling, and what researchers know about how people make and hold opinions.

The phrase “go with your gut” is often used to say one should follow their intuition in the face of a big decision. Recent research in the journal Nature Mental Health shows the gut really could have a big impact on mental health and decision-making. This study shows a clear link between people who handle stressful situations well and certain biological signatures in their microbiomes. Certain metabolites and gene activity in study participants were associated with high emotional regulation and cognition. These more resilient participants also had reduced inflammation and improved gut barrier integrity. The study builds on previous research that shows the brain and the gut are closely linked, and that a dysregulation in one can lead to a dysregulation in the other. Lead author Dr. Arpana Church, co-director of UCLA’s Microbiome Center and associate professor of medicine, joins Ira to talk about the study. They also discuss how probiotics could someday be a promising treatment for mental health conditions. Transcripts for each segment will be available after the show airs on sciencefriday.com.

As the surgeon general has stated, we are in a mental health crisis. Depression is the leading cause of disability worldwide. And a major challenge is that depression can be difficult to treat, especially for people who don’t respond well to talk therapy or antidepressants. But there’s a relatively new technique that seems to have a significant positive impact on people with treatment-resistant depression, even sending many of them into remission. It’s called transcranial magnetic stimulation (TMS) and it uses magnets to stimulate certain areas of the brain that play a role in depression. A team at Stanford developed a protocol for TMS that received FDA clearance in 2022 and, as of this year, it’s covered by Medicare. In a study from 2021, it was shown to improve remission rates for depression by up to 80%, with one patient calling it “a game changer.” So how does TMS work, and could it change the way we treat depression and other mental illnesses? Ira Flatow is joined by Dr. Nolan Williams, associate professor of psychiatry and behavioral sciences at Stanford University, where he’s also the director of the Stanford Brain Stimulation Lab. They talk about the advances that Williams’ team made with their SAINT protocol (Stanford Accelerated Intelligent Neuromodulation Therapy), patient experiences with the technology, and potential future applications of this technique.

The origin of life on Earth has been mulled over by scientists for centuries. We now know that life’s building blocks are RNA, amino acids, and cells. But if life originated from the primordial ooze of early Earth, could that process be unfolding elsewhere in the universe? The search for life elsewhere in the universe is at the center of the book Is Earth Exceptional?: The Quest for Cosmic Life, by Mario Livio and Jack Szostak. Dr. Livio, an astrophysicist previously with the Space Telescope Science Institute, which operates the Hubble Space Telescope, joins Ira to talk about the possibilities of life beyond Earth, and where we would most likely find it.

The storm flooded mines in Spruce Pine, North Carolina, which supply the tech industry with some of the purest quartz in the world. Also, researchers developed a 3D-printable material, inspired by worms, that can act as a Band-Aid for damaged heart and cartilage tissue. Hurricane Helene’s Damage Could Affect The Global Tech Industry After making landfall on September 26, Hurricane Helene devastated regions in the southeastern US. Over 200 people are confirmed dead so far. About a million people are still without power, and many lack clean water. As climate change intensifies, hurricanes like Helene are expected to occur more often and be more intense. What’s become very clear in the last few years is that due to the interconnectedness of the modern world, extreme weather in one place can have global implications. For example, Spruce Pine, North Carolina, home to around 2,200 people, flooded during Hurricane Helene. The town is also home to several mines that produce some of the world’s purest quartz, an ingredient necessary to make solar panels, smartphones, semiconductors, and more. Ira talks with Umair Irfan, senior correspondent at Vox, about this and other science news of the week, including a completed map of a fruit fly’s brain, how scientists in the United Kingdom are screening newborns for rare diseases, and how octopuses and fish are hunting as a team. A Strong, Stretchy, And Sticky Band-Aid For The Heart The heart is an impressive organ that has to beat constantly for years. But what happens when heart tissue is damaged? Or when cartilage in joints like our knees wears out? These constantly moving tissues don’t regenerate easily, and there aren’t a lot of great treatment options. To address these kinds of problems, a team at University of Colorado Boulder invented a new strong, stretchy, and sticky hydrogel material that could act as a Band-Aid to heart or tissue lesions. They were inspired by masses of worms that tangle and untangle themselves, behaving almost as both a solid and liquid. The team was able to replicate that in a molecular structure with the help of a new 3D-printing technique. And it could have applications far beyond medicine, including for manufacturing and improving the 3D-printing process itself. Their research was published in the journal Science, and their lab has filed for a provisional patent for the material. Dr. Jason Burdick, professor of chemical and biological engineering at CU Boulder’s BioFrontiers Institute, joins Ira Flatow to talk about the new material and how it could improve future tissue and cartilage treatment.

This summer, the Bureau of Land Management approved seven herbicides to fight invasive plants in the West. Also, when scientists analyzed the swirls in the famous painting, they found Van Gogh depicted forces of nature with startling accuracy. What Newly Approved Herbicides Could Mean For Federal Land Invasive plants are a big problem across the western US. Cunning interlopers like cheatgrass, leafy spurge and red brome can outcompete native vegetation, crowd habitats and steal water and other vital soil nutrients. Of the 245 million acres controlled by the Bureau of Land Management, harmful non-native plants have already infested 79 million acres—an area larger than the states of Pennsylvania, Virginia and South Carolina combined. That’s why the federal agency felt the urgency to approve seven new herbicides to kill invasives on its land nationwide, said Seth Flanigan, a BLM senior invasive species specialist based in Idaho. “If we don’t remove this now, what is it going to look like 10 years from now?” he said. Read the rest of this article on sciencefriday.com. The Hidden Physics In Van Gogh’s ‘The Starry Night’ One of Vincent Van Gogh’s most famous creations is “The Starry Night,” an oil painting of a quaint French village at night with a blue night sky that dramatically swirls around the yellow stars and moon. It’s easy to admire this painting as a casual viewer, but if you research fluid dynamics, one thing in particular stands out: those iconic swirls in the sky. To a physicist, they look an awful lot like the swirls that atmospheric turbulence produces. And some researchers have been wondering if Van Gogh’s swirls actually match the mathematical models of turbulence theory. Well, a team of researchers from China and France set out to analyze all the swirls in “The Starry Night,” and it turns out that Van Gogh had a knack for depicting the forces of nature. Their results were published in the journal Physics Of Fluid. Guest host Anna Rothschild sits down with Dr. Francois Schmitt, research professor in physics at the French National Centre for Scientific Research and co-author of the recent study, to talk about the hidden physics in this famous painting.

Emissions from anesthesia are one of the largest sources of greenhouse gases from hospitals. This anesthesiologist wants to change that. And, a cultural anthropologist discusses the Mariana Islands’ long history of colonization and why demilitarization matters for climate progress. A Major Source Of Greenhouse Gases In Hospitals? Anesthesia Did you know that some of the gases used in anesthesia are strong greenhouse gases? A few years ago, Seattle Children’s Hospital analyzed its carbon footprint and found that the gases used in anesthesia made up about 7% of the hospital’s total emissions, right behind emissions from heating and power and those from commuting. Faced with this problem, Dr. Elizabeth Hansen, a pediatric anesthesiologist at Seattle Children’s, took matters into her own hands and slashed the operating room’s emissions. She now helps other hospitals do the same with Project Spruce. Guest host Anna Rothschild talks with Dr. Hansen about how and why she took on the problem. Militarization And Environmental Injustice In The Mariana Islands Let’s take a trip to the Northern Mariana Islands, a string of islands in the Pacific just north of Guam. The islands were sites of major battles during World War II and were captured by the United States in 1944. The US established a military presence across the territory—including building the world’s largest air force base at the time, on an island called Tinian. The US military never left, and in the 1980s, the Northern Mariana Islands became a US territory. A few years ago, the Pentagon proposed building a bombing range on an island called Pagan, but residents of the islands pushed back. Dr. Isa Arriola is a cultural anthropologist at Concordia University in Montreal and co-founder of the organization Our Common Wealth 670, based in Saipan, the capital of the Northern Mariana Islands. She’s fought back against the militarization of her home islands, and she talks with guest host Anna Rothschild about how the military presence has affected the people and environment of the Marianas, and why demilitarization needs to be part of climate action.

If you’re a baby boomer, you may remember the first Earth Day, the Civil Rights Movement, anti-war protests, and the first Pride parade. The list goes on, because the 1960s and 70s were packed with social revolutions. But the organization Third Act has a message for boomers: Your work isn’t done yet. Third Act empowers folks over the age of 60 to get involved in the climate movement. It aims to leverage older generations’ access to power, money, and life experiences to create change. Ira Flatow talks with Third Act founder Bill McKibben and lead advisor Akaya Windwood about the importance of including older adults in the climate movement.

The company is betting big on nuclear energy to meet increasing power needs of data centers and new technologies like AI. Also, new research into a strange fish known as the sea robin finds that leg-like appendages can “taste” prey buried in the sand. Microsoft Makes Deal To Restart Three Mile Island Three Mile Island in Pennsylvania has quite a reputation in the world of nuclear energy: One of its reactors suffered a catastrophic partial meltdown in 1979, earning the title of the largest nuclear accident in US history. The failed reactor has been inoperable since the accident, while the other reactor shuttered in 2019. But now, tech giant Microsoft has made a deal with the nuclear site to reopen Three Mile Island, and purchase all of its generating capacity over the next 20 years. As Big Tech bets big on artificial intelligence, the need for electricity to power data centers is increasing tremendously. Former Microsoft CEO Bill Gates is a large investor in nuclear energy. To help Science Friday celebrate Climate Week NYC, Casey Crownhart, climate reporter for MIT Technology Review joins guest host Anna Rothschild to discuss this and other top climate stories of the week. These Fish Use Their Legs (Yes, Legs) To Taste Your legs may help you get around, but what if they could also help you sniff out a snack? That’s a trick achieved by a fish called the sea robin. The fish, which lives on the seafloor, has an unusual appearance, with wing-like fins and leg-like appendages that it uses to walk along the ocean bottom. But in work published this week in the journal Current Biology, researchers report that those legs are also chemical sensing organs that can taste for prey buried under the sand. Dr. Nicholas Bellono, a professor of molecular and cellular biology at Harvard, first learned of the unusual fish on a visit to the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, where he was planning to obtain squid and octopus for another research project. MBL workers showed Bellono and colleagues the sea robin, and explained that they have a reputation for being able to locate hidden prey—to the point that other organisms will follow the sea robin, hoping to get in on the meal. The intrigued researchers brought some sea robins back to the lab, and began a series of experiments to better understand their prey-sniffing abilities. Bellono joins guest host Anna Rothschild to talk about the fish, the genetic adaptations that allow it to sense the world through its legs, and the value of serendipity and curiosity-driven research in the scientific world.

In 2021, Dr. Francis Collins stepped down after a dozen years leading the National Institutes of Health. He had just overseen the government’s response to the COVID-19 pandemic,in the early days of changing public health guidance as scientists learned more about this new virus. He was also involved in the quickest development of a vaccine in history. Now, he’s had some time to reflect on how the US arrived at such a divisive place about COVID-19 and vaccines, how trust in science has dwindled, and what we can do about it. Ira sits down with Dr. Collins to talk about the lessons from his new book, The Road to Wisdom: On Truth, Science, Faith and Trust, and why he decided to speak publicly about his prostate cancer diagnosis.

Since ChatGPT was released to the public almost three years ago, generative AI chatbots have had many impacts on our society: They played a large role in the recent Hollywood strikes, energy usage is spiking because of them, and they’re having a chilling effect on various writing-related industries. But they’re also affecting the world of research papers and scientific publishing. They do offer some benefits, like making technical research papers easier to read, which could make research more accessible to the public and also greatly aid non-English speaking researchers. But AI chatbots also raise a host of new issues. Researchers estimate that a significant amount of papers from the last couple years were at least partially written by AI, and others suspect that they are supercharging the production of fake research papers, which has led to thousands of paper retractions across major journals in recent years. Major scientific journals are struggling with how to set guidelines for generative AI use in research papers, given that so-called AI-writing detectors are not as accurate as they were once thought to be. So what does the future of scientific publishing look like in a world where AI chatbots are a reality? And how does that affect the level of trust that the public has with science? Ira Flatow sits down with Dr. Jessamy Bagenal, senior executive editor at The Lancet and adjunct professor at University of North Carolina at Chapel Hill, to talk about how generative AI is changing the way scientific papers are written, how it’s fueling the fake-paper industry, and how she thinks publishers should adjust their submission guidelines in response.

The ring would have gradually fallen to Earth as meteorites, correlating to a spike of impacts seen in the geological record. Also, a new AI tool can judge whether sand came from a beach, a river, a glacial deposit, or a wind-blown dune. Earth May Once Have Had A Ring Like Saturn Hundreds of millions of years ago, Earth may have looked quite different when viewed from space: Scientists propose it may have had a Saturn-like ring, made up of lots of smaller asteroids. The new paper, published in Earth and Planetary Science Letters, proposes that this ring formed around 466 million years ago. A major source of evidence is a band of impact craters near the equator. The researchers also posit the ring would have shaded this equatorial area, possibly changing global temperatures and creating an icehouse period. Ira speaks to Rachel Feltman, host of the Popular Science podcast “The Weirdest Thing I Learned This Week,” about this and other top science stories of the week, including how lizards use bubbles to “scuba dive” underwater, and ancient cave art that possibly shows a long-extinct species. An AI To Identify The Environment A Grain Of Sand Came From If you were given a bucket of sand and asked to determine where it came from, you’d probably have a hard time guessing if it was from a beach, a riverbank, the playground down the street, or a Saharan sand dune. There are experts who can make a guess at that sort of ID, using a categorization process that takes skill, a scanning electron microscope, and hours of time. Now, however, researchers report in the Proceedings of the National Academy of Sciences that they’ve developed an AI model that can quickly judge whether a sample of sand came from a beach, a river, a glacial deposit, or a wind-blown dune. That type of identification isn’t just of interest to geologists. Sand is one of the world’s most in-demand resources, second only to water in use. And different applications need different types of sand—for instance, making concrete and mortar requires angular sand for good adhesion and stability. These kinds of needs have given rise to illicit sand mining, sand theft, and sand smuggling. A way of rapidly identifying the origins of a sample of sand could be useful to investigators, or to companies seeking to ensure sustainability goals. Michael Hasson, a PhD candidate in Stanford’s Department of Earth and Planetary Sciences, joins SciFri’s Charles Bergquist to discuss the new SandAI, and the challenges of tracking grains of sand.

The heaviest antimatter nucleus to date was spotted in a particle accelerator. It could provide new insights into the nature of matter. And, research indicates different songbird species might intentionally travel together during migration, giving each other a possible boost in survival. Physicists Create Heaviest Antimatter Nucleus Yet Antimatter is one of science’s great mysteries. It is produced all around us for fractions of a second, until it collides with matter, and the particles annihilate one another. But what is it? Antimatter is just like matter, except for one thing. Its particles have the same mass as ordinary matter, but an opposite charge. For example, an electron has a negative charge, so an anti-electron—called a positron—weighs the same, but has a positive charge. Antimatter is a natural product of some types of radioactive decay and cosmic ray collisions, but it can also be made in particle colliders here on Earth. But making antimatter particles this way is difficult and expensive—let alone controlling them enough to create an entire anti-atom. NASA estimates that creating a gram of antimatter would cost about $62.5 trillion. But why does antimatter matter? It may hold the key to understanding one of the universe’s biggest mysteries: why there’s something rather than nothing. Cosmologists say that during the Big Bang, matter and antimatter should have been created in equal amounts. But everything around us today is mostly matter, meaning either that there was an excess of matter created, or that matter and antimatter don’t quite follow the rules physicists expect. Recently, scientists at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider spotted 16 instances of the heaviest exotic antimatter nucleus observed to date: antihyperhydrogen-4. To explore what this breakthrough means for antimatter research, SciFri producer Charles Bergquist talks to Dr. Jamie Dunlop, associate department chair for nuclear physics at Brookhaven National Laboratory. Different Bird Species May Team Up For Migration This season, billions of birds will take to the skies as they flock to their wintering grounds. With so many different species on the move, they’re bound to run into each other. A new study in the journal Proceedings of the National Academy of Sciences suggests that this mixing and mingling might not be coincidental. In fact, different bird species could have their own social networks that might boost each others’ survival. SciFri producer Kathleen Davis talks with lead author Dr. Joely DeSimone, migration ecologist at the University of Maryland Center for Environmental Science Appalachian Laboratory, about untangling avian relationships.

SciFri producer Kathleen Davis talks with Dr. Kizzmekia Corbett-Helaire, assistant professor of immunology and infectious diseases at Harvard’s T.H. Chan School of Public Health to help answer our listeners’ top questions about the updated COVID-19 vaccines. This Q&A, which includes questions from our audience members, has been adapted from our interview with Dr. Kizzmekia Corbett-Helaire. It has been edited for clarity and brevity. If I’ve already had COVID and it wasn’t so bad, why should I even bother with this new booster? There’s always a chance that COVID-19 will cause more than the sniffles, or that you could end up in the emergency room—especially for older people. Why take that chance when you have the option to go to your local CVS and, in many cases, get a free vaccine that has been proven to decrease your chances of more severe disease? My hope is that as time progresses, people become more comfortable with the idea of getting seasonal vaccinations for COVID-19 along with flu. Is the new COVID-19 vaccine one shot? Yes.

Part of the reason it’s difficult to talk about climate change is that it can be hard to see a long-term positive outcome for people and the planet. But Dr. Ayana Elizabeth Johnson, a marine biologist and co-founder of the Urban Ocean Lab, argues that to prevent the worst effects of climate change, we have to start by asking ourselves, what if we get it right? She’s the author of a new book with that same title, What If We Get It Right? Visions of Climate Futures. In the book, she poses that question to experts in oceans, farming, architecture, finance, and even Hollywood to find out what getting it right looks like in their own fields and what those solutions could look like for the rest of us.

Kids and teens are back in school, and the battle over the smartphones in their pockets is becoming more prominent. For years, teachers and parents have lamented about the distractions these devices cause in and out of the classroom. Last year, the US surgeon general declared a youth mental health crisis, citing social media as a significant factor, and more than 40 US states are suing Meta, owner of Facebook and Instagram, arguing that the company intentionally manipulated their apps to addict teens and kids. A 2021 survey showed that 76% of US public schools prohibit cellphones. Seven states have implemented bans, and 14 more recently introduced similar legislation. To parents and educators, it might seem that phones and social media are bad for kids and bad for learning. But research shows that the reality is more complicated, with some suggesting that a blanket smartphone ban isn’t necessarily the solution. So what are the best ways to approach school phone bans? What do we know about the psychological effects of smartphones on kids and teens? And why does this research tend to defy simple answers? To answer these questions, guest host and SciFri producer Kathleen Davis is joined by Dr. Emily Weinstein, co-director of the Center for Digital Thriving at Harvard University, and the author of Behind Their Screens: What Teens Are Facing (And Adults Are Missing), and Sandy Roberts, education program manager at Science Friday and former middle school teacher.

SpaceX Crew Completes First Citizen Spacewalk Big news in the world of commercial space flight: On Thursday morning, Jared Iasaacman and Sarah Gillis, members of SpaceX’s Polaris Dawn mission, became the first civilians to complete a spacewalk. The mission is a collaboration between Elon Musk’s SpaceX and Isaacman, a billionaire tech entrepreneur. While outside the spacecraft, the two crew members conducted mobility tests on their spacesuits. SciFri Producer Kathleen Davis talks with Jason Dinh, climate editor at Atmos Magazine about this and other top science news of the week including deadly cholera outbreaks, germs at 10,000 ft, and Japanese eels that can escape a fish stomach through their gills. The First Successful Whole-Eye Transplant, Over A Year Later In May of 2023, there was a massive advance in the world of organ transplantation: the first whole human eye and partial face transplant. The man at the center of this procedure is 46-year-old Aaron James, who sustained significant facial injuries from a high-voltage work accident. At the time, it was unclear just how successful the operation would be. Previous tests in animals had resulted in shrinkage of the transplanted eye, if not outright rejection. But now, more than a year after the transplant, a new paper in the journal JAMA outlines the success of this first-of-its-kind operation. While James cannot see out of his new eye, there is blood flow, normal pressure, and a retinal response to light. Guest host Kathleen Davis speaks with Dr. Daniel Ceradini, director of research at NYU Langone’s Department of Plastic Surgery and first author of the JAMA study. They discuss the implications this success could have for the future of eye surgery, and the dramatic improvements in James’ quality of life.
