At the beginning of May, the National Institutes of Health, part of the Department of Health and Human Services, announced a plan to develop a universal vaccine platform. Think: a single shot for flu or COVID-19 that would last years, maybe a lifetime. The plan—called Generation Gold Standard—has a reported budget of $500 million, and a tight deadline. But will it work? And where does the science on this actually stand? In this live broadcast, Hosts Flora Lichtman and Ira Flatow talk with epidemiologist Michael Osterholm and vaccine researcher Ted Ross.Guests: Michael Osterholm is Director of the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota in Minneapolis, Minnesota.Dr. Ted Ross is the global director of vaccine research at the Cleveland Clinic's Florida Research and Innovation Center in Port St. Lucie, Florida. Transcript will be available after the show airs on sciencefriday.com.

The science fiction film “Interstellar” 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, could've made it into the movie.Universe of Art is hosted and produced by D Peterschmidt, who also wrote the music.

Since January 7, wildfires have been devastating the Los Angeles area. In the span of 10 days, several different fires, including the Palisades and Eaton fires, have burned more than 40,000 acres and destroyed more than 12,000 structures. At least 25 people have died.The threat of fire is growing, especially in zones known as the wildland-urban interface, or WUI. That's where unoccupied wildland and human developments meet and mingle. Think of a city sprawling around a forest, for example. In the US, around one in three homes is in this type of high-risk zone.So what's the science behind urban fires? And how do we protect ourselves in the face of them?Ira Flatow talks with Dr. Kimiko Barrett, senior wildfire researcher and policy analyst at the research group Headwaters Economics in Bozeman, Montana; and Dr. Alexandra Syphard, senior research scientist at the Conservation Biology Institute in San Diego, California.Transcripts for each segment will be available after the show airs on sciencefriday.com.

For years, artificial intelligence companies have heralded the coming of artificial general intelligence, 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.” 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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

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. 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 WindsThis week, the Los Angeles area has been battered by at least five separate wildfires. 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.On the other side of the country, Winter Storm Blair 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.Joining Ira Flatow to discuss these and other top stories of the week is Umair Irfan, science correspondent at Vox, based in Washington, D.C.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Last October, Ira Flatow took a trip to the World Forestry Center in Portland, Oregon, for a daylong exploration of lichen—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 to their striking colors and forms, we've really taken a lichen to these amazing organisms.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

This winter marks the 125th year of Audubon's Christmas Bird Count, in which bird nerds across the Western Hemisphere venture outside to record all the birds they see and hear.Scientists use that data to understand how birds are faring, where they're moving, and what they're up to when it's not breeding season. With 125 years under its belt, the Christmas Bird Count is the longest-running community science program in the world.How do scientists use this data? And what have they learned in those 125 years? Ira Flatow talks with Dr. Brooke Bateman, senior director of climate and community science at the National Audubon Society, and Dr. Janet Ng, wildlife biologist at Environment and Climate Change Canada in Regina, Canada.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Ira Flatow wants to turn science...into dinner conversation. The host and creator of Science Friday has spent a career quenching our curiosity, and his, and making science accessible. But amidst the fun are serious issues, like water shortages, climate change, genetic engineering, and artificial intelligence. We replay a conversation from August, when Flatow was in Colorado and spoke with CPR Southern Colorado Reporter Dan Boyce in front of an audience. 

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 2024December 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 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. 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 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, 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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

On December 24, NASA's Parker Solar Probe 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, 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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The microbiome, the network of tens of trillions of microbes 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, 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. 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.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

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, 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 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.Transcript for this segment will be available after the show airs on sciencefriday.com.

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 VapesOn 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. 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 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, 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 ExplodeLithium-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.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. 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. 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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

In 2022, the Nobel Prize in Chemistry went to Dr. Carolyn Bertozzi of Stanford University, Dr. Morten Meldal of the University of Copenhagen, and Dr. K. Barry Sharpless of the Scripps Research Institute “for the development of click chemistry and bioorthogonal chemistry.” In “click chemistry,” molecular building blocks snap together quickly and efficiently to let chemists build more complicated molecules. But bioorthogonal chemistry takes that work one step further, allowing the technique to be used within living organisms without damaging cells.“When someone is thinking outside the box, or in a very different way, we like to think of that as orthogonal thinking,” Bertozzi explained. “So biorthogonal means not interacting with biology. Totally separate from biology.” Her research began with an interest in developing ways to see specific sugar molecules on the surface of cells. But it has developed into an approach that can be used for advanced drug delivery in fields such as chemotherapy.As part of Science Friday's 33rd anniversary show, we're revisiting our listeners' favorite stories, including this one. In 2022, Bertozzi joined Ira Flatow for a wide-ranging conversation about her research, chemistry education, her early music career, and the importance of diversity in the field of chemistry.Transcripts for each segment will be available after the show airs on sciencefriday.com.

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. Transcripts for each segment will be available after the show airs on sciencefriday.com.

In a Chinese study, donor CAR-T cells sent autoimmune diseases into remission. There's hope that the therapy is scalable. And, scientists used decades of yellow-bellied marmot research to find a way to measure how adverse events affect wild animals' survival.CAR-T Cell Therapies Show Promise For Autoimmune DiseasesFor decades, immunologists have explored CAR-T cell therapy as an effective tool to fight blood cancer. Increasingly, CAR-T cells are being explored as a potential silver bullet for treating autoimmune diseases, like lupus—which currently have no cure.Thus far, CAR-T cell therapy has largely used CRISPR-modified immune cells from a person to treat that person's own diseases. But new research from China has made a huge step forward for this treatment: Researchers were successful in using donated CAR-T cells from one person to treat another person's systemic sclerosis, an autoimmune condition that causes atypical growth of connective tissues.If donor CAR-T cell therapy does indeed work, as posited in this paper, it could mean the therapy is more scalable than it would be otherwise. Joining Ira to talk about this study and its potential impact is Daniel Baker, PhD student in the immunology lab of Dr. Carl June at the University of Pennsylvania.Measuring The Effects Of Early Life Adversity—In MarmotsIt's well-established in psychology that if you experience trauma as a child, chances are it'll impact your physical and mental health as an adult, and could even affect your economic status. In academic terms, this is called early childhood adversity. And psychologists have developed a scoring system for measuring the cumulative effect of adverse childhood experiences, which can include abuse and household dysfunction, and it can help predict health risks later in life.So we can specifically measure that in humans. But what about other animals? If you've adopted a dog that's had a turbulent past, you know that that can result in reclusive or skittish behavior as an adult. But there hasn't been a good way to measure it in wild animals.Well, a new study from UCLA, published in the journal Ecology Letters, establishes a similar index for wild animals, and it used decades of findings from a mammal: the yellow-bellied marmot. So how could it help conservation efforts for other animals?Ira Flatow talks with Xochitl Ortiz-Ross, a PhD student in ecology and evolutionary biology at UCLA, and one of the authors on that study.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Abortion was on the ballot in 10 states, and seven of them passed constitutional amendments defending abortion rights. Also, this ginormous number has a whopping 41,024,320 digits, which isn't very helpful for mathematicians but is certainly exciting for math nerds.Seven States Passed Ballot Measures To Protect Abortion RightsThis week, science was on the ballot in many states. Voters across the country weighed in on issues like drug legalization, money to fund climate programs, and, of course, abortion rights. Ten states voted on the issue, and in seven of them, voters chose to protect or expand abortion rights. Those states are Maryland, Montana, Nevada, New York, Colorado, Arizona, and Missouri. On the flip side, voters in Florida, Nebraska, and South Dakota rejected measures that would protect abortion rights.Ira Flatow talks with Tim Revell, executive editor at New Scientist, about the outcome of some sciencey ballot measures and what we can expect going into another Trump presidency. They also discuss the launch of the world's first wooden satellite, what scientists learned when they put vampire bats on a treadmill, and more.Math Enthusiast Finds The Largest Known Prime NumberLet's go back to grade school—do you remember learning about prime numbers? They're numbers that can only be divided by themselves and one.So 2, 3, 5, 7, 11, and so on are prime numbers. The number 12, for example, wouldn't be prime because you can divide it by other numbers, like 2 and 3. And as you count up and up, prime numbers become more sparse.Math lovers are always competing to find the largest prime number, and just recently, an engineer discovered the largest one—so far. And you won't believe how ginormous it is: It has more than 41 million digits.Ira talks with Jack Murtagh, math writer and columnist for Scientific American, about why prime numbers are so cool, and the quest to find the largest one.Transcripts for each segment will be available after the show airs on sciencefriday.com.

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.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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

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 IndustryAfter 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 HeartThe 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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

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.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The space elevator has been a staple of science fiction for decades, from The Fountains of Paradise by Arthur C. Clarke to the Apple TV show “Foundation.” But the work and theories to make it a reality have been in development since the late 19th century.It's a simple concept: Imagine a long cable, stretching from the Earth's surface to a satellite locked in orbit 22,000 miles high. It would work like elevators here on Earth, enabling us to send things—and people—up into space. And it would make the need for the expensive rockets we use today obsolete.Although it has never been considered feasible due to the exorbitant cost and the engineering challenges it poses, the idea refuses to go away.One of Japan's biggest construction companies, the Obayashi Corporation, which built the Tokyo Sky Tree, had plans to build a space elevator in 2025 but has reportedly delayed that goal.So what are the hurdles that keep us from building it? And why does it seem that the space elevator is always 25 years away? Ira Flatow is joined by Dr. Dennis Wright, president of the International Space Elevator Consortium to talk about the feasibility of this megaproject.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Data from the Mars InSight lander points to the presence of liquid water underneath its crust. Also, some national and state parks are changing the way they open up campsite reservations online to make them more accessible to everyone.Scientists Find Strong Evidence For Liquid Water On MarsScientists discovered that there could be oceans' worth of liquid water hidden underneath Mars' surface. More than 3 billion years ago, Mars had lakes, rivers, and maybe even oceans on its surface. It was very different from the arid red planet we know today.But the question remains—when Mars' atmosphere changed, where did all that water go? This discovery could offer up new clues and possibly spur on the search for life on Mars.Ira talks with Maggie Koerth, science writer and editorial lead for Carbon Plan, about this discovery and other science news of the week, including why the WHO declared mpox a global health emergency, the microbiome of your microwave, a green-boned dinosaur named Gnatalie, and how love is in the air for brown tarantulas.Releasing Campsite Reservations In Waves Makes Booking FairerBack in 2022, Science Friday discussed how campsites in state and national parks were virtually impossible to reserve, unless you had a lot of time on your hands and knew exactly when those reservations were going online. Research had shown that the people able to reserve these sites were often wealthy, educated, and white, leaving lots of other people out of the fun of camping.But two years later, the same team that found those results says there's good news: Many state and federal campgrounds have changed how their booking windows work, and as a result, camping has become more equitable.For example, Saddlehorn Campground near Grand Junction, Colorado, was identified as a campground with an inequitable reservation system in a 2022 study. After its publication, campground managers reached out to the study authors to see how they could do better.“They've created what I would call the gold standard in an equitable recreation rationing spectrum for these campsites,” said Dr. Will Rice, assistant professor of outdoor recreation and wildland management at the University of Montana in Missoula.This method is to release campsites in waves: Some become available six months in advance, some two weeks in advance, and some day-of. This allows more flexibility for people to book, and is an easy fix on the part of the campgrounds.Rice joins Ira Flatow to talk about these advancements. Since his first appearance on Science Friday, Rice has testified before Congress about the importance of camping reservation equity, and has helped both federal and state campgrounds change their booking reservation windows.Transcripts for each segment will be available after the show airs on sciencefriday.com.

It's become clear to farmers and home gardeners alike that climate change is affecting the gardening landscape, literally. The climate is warming, pests are moving into different regions, and there's a growing need for vegetable varieties that are resilient to the stresses of this new age.In the world of organic farming, the job of creating those new varieties falls to a plant breeder: someone who, often painstakingly, crosses plants until they create a new variety. Dr. Jim Myers, one of the most accomplished plant breeders in the country, has lots of experience with this.Myers created the Indigo Rose tomato, a strikingly purple variety with the same antioxidants as blueberries. He also created the green bean cultivar predominantly used by Oregon producers, and is debuting two new varieties of low-heat habanero peppers next month, dubbed “Mild Thing” and “Notta Hotta.”Myers joins Ira Flatow from Corvallis, Oregon, where he's a professor of agricultural science at Oregon State University. They discuss his decades-long career in plant breeding and what he sees as the biggest challenges for the plant breeders of the future. Subscribe to this podcast.

The Boeing capsule is having issues with its thrusters and cannot bring astronauts back to Earth. Also, move over, Farmer's Almanac. A more accurate long-term weather forecast could be on the horizon.Boeing's Starliner Leaves Astronauts Stuck On The Space StationIn another blow to Boeing's Starliner program, which is meant to ferry astronauts and supplies to the International Space Station, NASA announced Wednesday that the troubled spacecraft would not be able to take astronauts Suni Williams and Butch Wilmore back to Earth due to issues with its thrusters.The two astronauts arrived at the International Space Station in June for a mission that was supposed to last eight days. But with the current problems, the pair might be stuck on the space station, where Starliner remains docked, until early next year. NASA is considering bringing them back in an upcoming SpaceX Dragon mission.Ira Flatow is joined by Umair Irfan, senior correspondent at Vox, who breaks down this and other top science stories this week, including how the Olympic Games are adjusting to abnormally high temperatures in France, why the EPA banned a widely used weedkiller, and what the moon's atmosphere is made of.Could We Get Weather Forecasts Years—Or A Decade—In Advance?Access to weather forecasts has been made easier than ever with the advent of smartphones. Most of the time, we can get accurate information about weather for the next few hours up through the next few days. But a week or two out, those predictions get less reliable.In the near future, it may be possible to get accurate weather forecasts weeks, months, or even a decade ahead of schedule. While this sounds like science fiction, researchers at the National Center for Atmospheric Research (NCAR) are working on this very challenge.Earth system predictions, as the field is called, combines a variety of factors including atmospheric conditions, ocean currents, and even what's happening in the soil to form predictions. These forecasts are in high demand as the climate changes, particularly as farmers need more information about incoming heat and precipitation. There's even the possibility that Earth systems predictions could help regions prepare for dangerous natural hazards well ahead of time.At Science Friday Live in Boulder, Colorado, Ira sat down with two NCAR scientists, Dr. Yaga Richter and Dr. Jerry Meehl about their work in this field.Transcripts for each segment will be available after the show airs on sciencefriday.com.

If nations are to meet their sustainable energy goals, experts argue that batteries will be a crucial part of the equation. Not only are batteries key for many technologies, they'll also be necessary to meet energy demands with a power grid that is mainly supplied by renewable energy sources like wind and solar. Without batteries, power from those sources can't be stored for use when the sun isn't shining or the wind isn't blowing.Right now, many technologies depend on lithium-ion batteries. While they certainly work well and have revolutionized mobile devices and electric vehicles, there are drawbacks. First, the lithium, cobalt, and nickel they require can only be found in some countries, and there have been accusations of unethical mining practices, including child labor. The mining and production processes also emit a large amount of CO2, and the batteries themselves can explode and cause fires, although these incidents are becoming less common.A promising, greener solution to our battery needs could be something called a solid-state battery. Lithium-ion batteries conduct electricity through a liquid electrolyte solution, while solid-state batteries do so with solid materials, such as ceramic, glass, and sulfides. This means they have lower risk of fires, charge faster, have higher voltages, and can be recycled. However, their development has taken longer than expected, due to cost, production hurdles, and lack of large-scale, real-world testing.Earlier this month, teams at the University of Chicago Pritzker School of Molecular Engineering and the University of California San Diego published a paper in Nature Energy demonstrating the world's first anode-free, sodium-based, solid-state battery architecture, which can charge quickly and last for several hundred cycles. Its main ingredient, sodium, is much more abundant than lithium, cobalt, and nickel, which could mean more affordable and environmentally friendly batteries in the future.Ira Flatow sits down with Dr. Y. Shirley Meng, a professor at the University of Chicago Pritzker School of Molecular Engineering and chief scientist for energy storage science at Argonne National Laboratory, to talk about the advancement, and when we could expect to see these unique batteries in our devices.Transcript for this segment will be available after the show airs on sciencefriday.com.

In 2005, futurist and inventor Ray Kurzweil popularized the term “the singularity” to capture the idea that man and machine will merge as the next stage of evolution. This was the basis for Kurzweil's book The Singularity is Near, which has been essential reading for technology buffs and critics since its publication nearly 20 years ago.In the meantime, we've seen huge advances in artificial intelligence, computing power, and technological research. In response to all this growth, Kurzweil has published a followup to bring us up to date, The Singularity is Nearer: When We Merge With AI. Ira Flatow speaks to Kurzweil about the book and his more than six decades of experience in the field of artificial intelligence.Read an excerpt from The Singularity is Nearer: When We Merge With AI.Transcript for this segment will be available after the show airs on sciencefriday.com.

Plants called “hyperaccumulators” have evolved to absorb high levels of metals. Scientists want to harness them for greener metal mining. And, a little fern from New Caledonia is just a few inches tall, but its genome has 160.45 billion base pairs—50 times more DNA than a human.How Metal-Absorbing Plants Could Make Mining GreenerScientists are exploring a somewhat unusual green energy solution: mining metals from the earth using plants.Typically, if soil has high levels of metal, plants will either die or do everything they can to avoid it. But, one group has taken a different path: evolve to be able to safely absorb large amounts of the metals. These special plants are called hyperaccumulators. And their ability to suck metals like nickel from the earth is called phytomining.The Department of Energy's Advanced Research Projects Agency-Energy announced in March up to $10 million in funding for phytomining research.Ira talks with Dr. David McNear, professor of plant and soil sciences at the University of Kentucky, about these fascinating flora and their promise as a greener option to metal mining.A Tiny Fern Has The Largest Genome Ever DiscoveredScientists just discovered the largest genome of any living thing on Earth, and it belongs to a small, unassuming fern called Tmesipteris oblanceolata. If you were to split open one of its cells and unwind the DNA that's coiled up in the nucleus, it would stretch out more than 300 feet—taller than the Statue of Liberty.Scientists reported the finding last week in the journal iScience. The fern is only a few inches tall and is found on the island of New Caledonia in the Southwest Pacific. Its DNA is made up of 160.45 billion base pairs—50 times more than the human genome.This finding has left scientists scratching their heads, wondering how and why a fern ended up with so much DNA. Ira Flatow talks with co-lead author of this study Dr. Jaume Pellicer, evolutionary biologist at the Botanical Institute of Barcelona, about this research and why this fern's DNA is so puzzling.Transcripts for each segment will be available after the show airs on sciencefriday.com.

DNA has long been studied and understood as the genetic blueprint for life on Earth. And related scientific endeavors, like the Human Genome Project, have received enormous attention. But DNA's lesser-known counterpart, RNA, which translates the instructions from those blueprints into proteins in our cells, has received far less focus.But a lot's changed in the last few years. The success of the mRNA COVID vaccines has led to a renewed interest in the potential medical therapies for this tiny molecular powerhouse, with applications ranging from CRISPR gene-editing to an mRNA-based cancer vaccine.Dr. Thomas Cech, distinguished professor in biochemistry at University of Colorado, Boulder, and the author of the book The Catalyst: RNA and the Quest to Unlock Life's Deepest Secrets, joins Ira Flatow to tell us how why RNA has gotten the shorter end of the research stick for so long, how it could help us understand the origins of life, and why this misunderstood molecule might be the key to a next generation of big scientific discoveries.Read an excerpt from The Catalyst: RNA and the Quest to Unlock Life's Deepest Secrets at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Rare earth elements are a group of 17 metals used in a wide range of things that make modern life possible, including batteries, magnets, LED light bulbs, phone screens, and catalytic converters.These elements are essential to a green economy because they are integral to many technologies designed to have low environmental impact. However, mining these metals is a dirty, complex, and costly process. And as the world transitions towards more clean energy production, the demand for them will continue to grow.One possible solution is to recycle rare earth elements when they're discarded in electronics waste. On stage in Ames, Iowa, Ira Flatow talks with Dr. Ikenna Nlebedim and Dr. Denis Prodius, two materials scientists from the Critical Materials Institute at the Ames National Laboratory who have developed a new acid-free method to recycle rare earth metals found in magnets.Transcript for this segment will be available the week after the show airs on sciencefriday.com.

The U.S. Preventive Services Task Force has updated its recommendations for breast cancer screening once again. The recommendations now stipulate that women and people assigned female at birth should begin getting mammograms at age 40, and continue every other year until age 74. The previous guidelines recommended beginning screening at age 50. These guidelines carry a lot of weight because they determine if mammography will be considered preventive care by health insurance and therefore covered at no cost to the patient.Why have the guidelines changed? And how are these decisions made in the first place? To answer those questions and more Ira Flatow talks with Dr. Janie Lee, director of breast imaging at the Fred Hutchinson Cancer Center and professor of radiology at the University of Washington School of Medicine.Transcript for this segment will be available the week after the show airs on sciencefriday.com.

Upgrades to the power grid under a new rule could help accommodate an increasing renewable energy supply and meet data center demands. Also, extremely small particles might help scientists develop vaccines that are stable at room temperature and easier to administer.New Rule Sets Stage For Electric Grid UpdateThe US electric grid is straining to keep up with demand. For starters, our warming climate means more electricity is needed to keep people cool. Last summer—which was the hottest on record—energy demand in the US experienced an all-time hourly peak. And even though more renewable energy is being produced, our current grid, largely built in the 1960s and 1970s, was not built to handle those needs. Increased use of AI and cryptocurrency, which require power-hungry data centers, have only increased the burden on the grid.But on Monday, the Federal Energy Regulatory Commission approved new rules to upgrade the grid to accommodate rising demands. The policy includes approval for the construction of new transmission lines and modification of existing transmission facilities.Casey Crownhart, climate reporter for the MIT Technology Review, joins Ira to talk about this and other science stories of the week, including how a recent ocean heatwave will impact ocean life and the upcoming hurricane season, a new self-collection test for cervical cancer, and how a tiny beetle uses audio mimicry to avoid being eaten by bats.Could Vaccines Of The Future Be Made With Nanoparticles?In 2021, vaccines for COVID-19 were released, a little over a year after the SARS-CoV-2 virus triggered a global pandemic. Their remarkably short production time wasn't the result of a rush-job, but a culmination of decades of advancements in infrastructure, basic science, and mRNA technology.But despite the years of innovations that allowed those vaccines to be developed and mass-produced so quickly, their delivery method—an injection—still has some drawbacks. Most injected vaccines need to be kept cold, and some require multiple trips to a pharmacy. And people with needle phobias may be reluctant to get them altogether. So what could the vaccines of the future look like?Dr. Balaji Narasimhan, distinguished professor and director of the Nanovaccine Institute at Iowa State University, joins Ira Flatow onstage in Ames, Iowa, to talk about how his lab is using nanotechnology to develop the next generation of vaccines, and how they could be more effective than current vaccines in the face of the next pandemic.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

Science Friday is in Ames, Iowa, home to prairies, greater prairie chickens, and an array of wildlife. Also, the co-emergence of two periodical cicada broods is underway. Scientists have tips for how to experience the event.Science From Iowa's PrairiesThis week, SciFri is coming to you from Ames, Iowa. We're kicking off the sciencey Iowa celebrations by spotlighting some of the plants, animals and unique ecosystems of the Hawkeye state. Ira talks with Charity Nebbe, host of the “Talk of Iowa” at Iowa Public Radio, about the state's largest prairie restoration project, the conservation of prairie chickens, and its rebounding wildlife.Planning To Go See Cicadas? Here's What To KnowIn parts of the American South and Midwest, two broods of cicadas are emerging: Brood XIX, known as the Great Southern Brood, and Brood XIII, called the Northern Illinois Brood.The dual emergence of these two particular broods is a rare event, since the Great Southern Brood emerges on a 13-year cycle and the Northern Illinois Brood emerges on a 17-year cycle. The last time they were seen together was in 1803. The two could overlap this spring in parts of Illinois and Iowa, where cicada enthusiasts will gather in parks to observe the emergence.“Plan to spend an afternoon or two,” recommends entomologist Dr. Laura Iles from Iowa State University. “Here in Iowa it tends to be pretty patchy even within a park, so talk to someone, a ranger, about what path to hike on and the best places to go see them.”Ira Flatow speaks with Dr. Iles about the fascinating life cycle of cicadas, how best to approach cicada tourism, and why gardeners should hold off on planting new trees this year.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Springtime is a great reminder of just how beautiful trees can be. Cherry blossoms and magnolias put on a gorgeous show, but trees aren't just there to look good. They play an important role in absorbing heat, sequestering carbon dioxide, and preventing soil erosion.Dr. Mike Alonzo, assistant professor of environmental science at American University, is using satellites to determine just how effective urban trees are at keeping neighborhoods cool. He's been able to track changes to the tree canopy over time, and identify when during the day trees do their best cooling work.In Baltimore, Ryan Alston with the Baltimore Tree Trust has been working with the community to help residents understand the importance of planting trees. The city has a history of redlining, which affected the number of big trees in historically Black neighborhoods, leading to major differences in how hot certain neighborhoods get in the summer.Alonzo and Alston join Ira Flatow live on stage at George Washington University to discuss the power of urban trees.The transcript for this segment will be available the week after the show airs on sciencefriday.com.

A Massachusetts man who received a kidney from a genetically modified pig is recovering well. Also, on April 8, a total solar eclipse will plunge parts of North America into darkness. Scientists answer the questions you asked.Recipient Of Pig Kidney Transplant Leaves The HospitalLast month, Massachusetts General Hospital in Boston announced that a team of doctors had transplanted a kidney from a genetically engineered pig into a living human for the first time. This week, that patient, a 62-year-old man living with end-stage kidney disease, was sent home from the hospital, having recovered enough to be discharged. Sixty-nine genes were edited in the donor pig, including three that coded for a certain sugar found on the surface of pig cells. The edits, hopefully, will make it less likely for the human recipient to reject the transplant.Umair Irfan, senior correspondent at Vox, joins Ira Flatow to talk about the xenotransplantation advance, and how it could affect patients awaiting donor organs. They'll also talk about other stories from the week in science, including how power grid operators are preparing for the upcoming solar eclipse, NASA's search for a new lunar rover, an advance in getting robots to make appropriate faces, research into using a drug similar to the obesity medication Ozempic to delay Parkinson's symptoms, and plans for a new time zone—on the moon.Answering Your Questions About Monday's EclipseAfter months of excitement, the 2024 total solar eclipse is almost here! On Monday, April 8, the moon will line up perfectly between the Sun and the Earth. For a few short minutes, it'll plunge parts of North America into total darkness—right in the middle of the day.More than 30 million people live in the path of totality—where the moon will completely block off the sun. It stretches from northwest Mexico, across the US, and into southeastern Canada. Depending how far you are from the path, you might experience a partial eclipse. Magical, nonetheless.Ira talks with Dr. Padi Boyd, astrophysicist at NASA and host of the agency's podcast Curious Universe, and Mark Breen, meteorologist and planetarium director at the Fairbanks Museum & Planetarium in Vermont. They answer questions our readers and listeners have submitted about the eclipse, and discuss why we should be excited, how to prepare, and what scientists can learn from this phenomenon.For more eclipse-day tips and facts, visit our website.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

The World Meteorological Organization's report confirms last year had the highest temperatures on record and predicts an even hotter 2024. Also, NASA's new PACE satellite will study how these tiny creatures could affect Earth's climate, and how aerosols influence air quality.UN Report Confirms 2023 Was Hottest Year On RecordA new report from the United Nations' World Meteorological Organization shows that last year had the hottest average global temperatures since recording began 174 years ago. Ocean temperatures also reached a 65-year high last year, and 2024 is on track to be even hotter.Ira talks with Jason Dinh, climate editor at Atmos Magazine about that and other top science news of the week including cannibal birds, fighting Dengue fever with bacteria-infected mosquitos and the evolutionary benefit of whale menopause.Why This NASA Satellite Is Studying PlanktonDid you know you can see plankton … from space? Earlier this year, NASA launched a satellite to do exactly that. It's called PACE, which stands for Plankton, Aerosol, Cloud, and ocean Ecosystem, and NASA hopes that the satellite can tell us more about how these tiny creatures interact with Earth's atmosphere and influence our climate.Some species of plankton, called phytoplankton, are microscopic plants that absorb carbon dioxide and produce oxygen. PACE has equipment that can identify different species of phytoplankton by the kind of light they give off, giving NASA real-time information about their location and population size, which can also aid fisheries and coastal communities when algal blooms occur.PACE will also study how aerosols affect air quality on Earth. Additional instruments on the satellite can differentiate between different kinds of aerosols by studying how they reflect light back into space, which will help scientists refine their climate models so that more accurate forecasts can be made.Ira Flatow talks to Dr. Ivona Cetinic, PACE's science lead for ocean biogeochemistry, about the satellite, her favorite species of plankton, and how the public can benefit from the data that the mission will provide.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

The field of chemistry is filled with visual experiences, from molecular diagrams to color-changing reactions to data displayed as peaks and waves on a spectrograph. Those experiences and representations are not very accessible to blind and low-vision people. In a recent article in the journal Science Advances, a group of researchers describes using 3D printing to create translucent raised images known as lithophanes that can represent high-resolution chemical data in a tactile and visual form simultaneously.Biochemist Dr. Bryan Shaw joins Ira Flatow to discuss the approach, and other techniques and tools his lab group at Baylor University is developing to make the lab more accessible to blind and low-vision researchers—from specialized devices that assist in the loading of gels for protein electrophoresis, to tiny molecular models that are best experienced by putting them on the tongue.Transcripts for each segment will be available the week after the show airs on sciencefriday.com Subscribe to this podcast.

The explosion of AI-powered chatbots and image generators, like ChatGPT and DALL-E, over the past two years is changing the way we interact with technology. Their impressive abilities to generate lifelike images from written instructions or write an essay on the topic of your choosing can seem a bit like magic.But that “magic” comes at a steep environmental cost, researchers are learning. The data centers used to power these models consume an enormous amount of not just electricity, but also fresh water to keep everything running smoothly. And the industry shows no signs of slowing down. It was reported earlier this month that Sam Altman, the CEO of leading AI company OpenAI, is seeking to raise about $7 trillion to reshape the global semiconductor industry for AI chip production.Ira Flatow is joined by Dr. Jesse Dodge, research scientist at the Allen Institute for AI, to talk about why these models use so much energy, why the placement of these data centers matter, and what regulations these companies could face.Transcripts for this segment will be available the week after the show airs on sciencefriday.com Subscribe to this podcast.

There has been a boom of syphilis cases, including a 180% increase in congenital syphilis cases, despite other STI levels staying stable. Also, the world's largest deep-sea reef stretches for hundreds of miles in near-freezing waters and total darkness, but it's bustling with life.Syphilis Cases Are Up 80% Since 2018Syphilis is rearing its ugly head again in the United States. A new report on sexually transmitted infections (STIs) from the Centers for Disease Control and Prevention shows a shocking statistic: Cases of syphilis are up by nearly 80% among adults since 2018. Congenital syphilis cases, which occur when an infection is passed from parent to child during pregnancy, are up by more than 180%.Strangely, cases of other STIs have stayed about the same or decreased in the same timeframe. Rachel Feltman, host of “The Weirdest Thing I Learned This Week,” joins Ira to talk about this and other science stories from the week, including the first cases of transmitted Alzheimer's disease, and why closing the toilet seat doesn't keep aerosolized viruses from contaminating other bathroom surfaces.Revealing The Largest Deep-Sea Coral Reef In The WorldScientists recently discovered the largest known deep-sea coral reef in the world. It's called Million Mounds, and it stretches from Miami, Florida, to Charleston, South Carolina, covering around 6.4 million acres of the seafloor.Unlike the colorful reefs found in sunlit tropical waters, this one is mostly made up of a stony coral that's usually found from about 650 to 3,300 feet underwater—depths where it's very cold and pitch black.Ira Flatow talks with Dr. Erik Cordes, marine biologist and professor at Temple University in Philadelphia, Pennsylvania, who collaborated on the study. They discuss what makes deep-sea corals different from those found in shallower waters, why it's important to map them, and what it's like to visit one in a submarine.Transcripts for each segment will be available after the show airs on sciencefriday.com.

For almost their entire 4.5 billion-year existence, Earth and its moon have been galactic neighbors. And the moon isn't just Earth's tiny sidekick—their relationship is more like that of siblings, and they're even cut from similar cosmic cloth.Without the moon, Earth and its inhabitants wouldn't be what they are today: The climate would be more extreme, lunar tides wouldn't have given rise to life on Earth, biological rhythms would be off-beat, and even timekeeping and religion would have evolved differently. The new book Our Moon: How Earth's Celestial Companion Transformed The Planet, Guided Evolution, And Made Us Who We Are explores how our existence is tied to the moon's.Ira Flatow and guest host Sophie Bushwick chat with journalist and author Rebecca Boyle about how the moon came to be, how it transformed life on Earth, and how our relationship with it is changing.Transcripts for each segment will be available the week after the show airs on sciencefriday.com To stay updated on all things science, sign up for Science Friday's newsletters.

The idea of creatures from another planet is part of our culture, from the warnings of the alien in “The Day the Earth Stood Still,” to the plaintive desire to return home in “E. T. the Extra-Terrestrial,” to the hulking creature of “Nope.” Aliens appear in movies, books, comics, you name it. But are they more than science fiction? And if they were, how would scientists prove it?The government has investigated reports of alien sightings, including in Project Blue Book, which ran from 1947 to 1969. And last summer, congressional hearings into Navy pilots' sightings of Unidentified Anomalous Phenomena (UAPs) brought the search for intelligent life back into the public eye. But there's more to the search for alien life than people spotting lights in the sky. Projects such as Breakthrough Listen are surveying the stars for signals. Advanced telescopes such as JWST are enabling us to collect data on the atmospheres of exoplanets, a first step in detecting biosignatures on distant worlds. And astrobiology projects such as the Mars 2020 Perseverance rover mission are looking for signs of ancient life elsewhere in our own solar system.Dr. Adam Frank, a professor of astrophysics at the University of Rochester and author of The Little Book of Aliens, joins hosts Ira Flatow and Kathleen Davis to talk about the evidence for life elsewhere in the universe, and how scientists might go about trying to answer the question of whether we're alone.Transcripts for each segment will be available after the show airs on sciencefriday.com.

COP28 Host Had Plans to Promote Oil and Gas, Documents ShowThe United Nations Climate Change Conference, COP28, began this week in Dubai. This is an annual event, where leaders and delegates from around the world come together to discuss how to collaboratively reach important milestones for the future of the planet. Goals like slowing the rise of temperatures on Earth will require buy-in from all major players to be successful.But this week, a document leaked that showed the United Arab Emirates planned something at odds with the event: promotion of the oil and gas industries. This has led to increased skepticism of COP and its goals among both critics and attendees.Ira is joined by Tim Revell, deputy US editor of New Scientist, to talk about this story. Plus, how a single bitcoin transaction uses enough water to fill a swimming pool, the way nutrients in soil drive biodiversity, and how amino acids could be formed alongside stars.Researchers Detected Cicada Emergence With Fiber-OpticsIf you were in the eastern United States during the summer of 2021, you likely heard the incessant, whirring buzz caused by the mass emergence of Brood X periodical cicadas. That event, which occurs once every 17 years, brought forth countless cicadas to shed their skins, mate, lay eggs, and die. But it turns out their arrival wasn't just something that you could witness out the lawn or against your car windshield. The sound of their emergence was something that could be detected by fiber-optic cables.Dr. Sarper Ozharar, a researcher who studies optical networking and sensing at NEC Labs in Princeton, New Jersey, has worked on techniques using fiber-optics to sense the vibrations of things like traffic, sirens, and gunshots. Loud noises produce vibrations that subtly distort optical “backscatter” within a glass fiber-optic cable. Using AI, researchers can decode those vibrations and determine what, and where, a noise may have occurred near the fiber.In the summer of 2021, Ozharar and colleagues detected an unusual frequency signal in their test data. With the help of entomologist Dr. Jessica Ware of the American Museum of Natural History, they eventually determined that it was the whirring of the cicada swarm. Their find is the topic of a report published this week in the Journal of Insect Science.Ozharar joins Ira Flatow to talk about how fiber-optic sensing works, and how an electronics and communications lab ended up publishing in an entomology journal. To stay updated on all things science, sign up for Science Friday's newsletters.
