Proposed budget cuts for NASA would jeopardize space research. And an executive order could change the political tides for deep sea mining.On May 2, the Trump Administration proposed a 24% budget cut for NASA. It would slash funding for science while setting billions aside for initiatives to send humans to the moon and Mars. New Scientist editor Sophie Bushwick joins us to talk about this, as well as other news in science, like how many U.S. cities are sinking, the search for geologic hydrogen within mountains, the first photos of free-floating atoms, Chinese poetry about porpoises, and cicadas turned into speakers.And, President Trump recently issued an executive order that would fast-track access for deep sea mining. Soon after, a Canadian company called The Metals Company submitted the first application for NOAA to review. This has raised environmental and climate concerns, as well as geopolitical tensions.

Episode 276 Are the COP climate summits doing enough to help us avoid the most devastating impacts of climate change, or are they not fit for purpose, and designed to fail? COP29 is underway in petrostate Azerbaijan, headed by a CEO who was secretly filmed making oil and gas deals. Despite this, the team finds reason for optimism. They also hear from climate philosopher and activist Rupert Read, who runs the Climate Majority Project. He argues the COP process was designed to fail, that 1.5 degrees is dead and that adaptation - not mitigation - is the way to go. What do you think? Bird migration is an extraordinary feat of evolution - but how exactly do they do it? We know the Earth's magnetic field has something to do with it, but we've only just discovered the astonishing level of detail birds are able to get from it. Raising questions about bird intelligence, the team also hears how birds evolved from dinosaurs. Gophers have an incredible capacity to shape their landscape. Gophers are small, burrowing rodents with long front teeth. And a decades-long study has shown that just one day of work by a gopher can completely revitalise soil in an area, changing its microbial diversity and preventing disease. Gopher productivity surely puts humans to shame. Hosts Rowan Hooper and Penny Sarchet discuss with guests Madeleine Cuff and Sophie Bushwick.

The Science Behind Third-Trimester Abortions

Leading up to the November election, Science Friday is covering top science issues on the ballot. For voters, those top issues include abortion.Since the Dobbs ruling overturned Roe v. Wade in June 2022, many states have curtailed access to abortion, and 13 states have a total abortion ban.The election season in particular, there's been a focus on abortions in the third trimester of pregnancy. Some of the political rhetoric is inflammatory and false. But even among politicians who support abortion rights, there's a tendency to deflect attention away from these procedures later in pregnancy.Though third trimester abortions are rare, they make up about 1% of abortions in the United States and are often the most stigmatized. They are legal in only a small number of states, and just a fraction of providers perform them.To better understand the real science behind abortions later in pregnancy, guest host Sophie Bushwick talks with Dr. Katrina Kimport, professor of obstetrics, gynecology & reproductive sciences at the University of California, San Francisco; and Dr. Cara Heuser, a maternal and fetal medicine physician who specializes in high risk pregnancy and complex abortion care, based in Salt Lake City, Utah.

Did Dinosaur Flight Evolve More Than Once? | Biodiversity's Biggest Event Is Underway

Some paleontologists argue the ancient footprints found in South Korea show flight may have evolved in multiple dinosaur lineages. And, COP16 will tackle questions like who should profit from non-human DNA, and who is responsible for financing critical conservation projects.Do Fossil Prints Show Dinosaur Flight Evolved More Than Once?Researchers studying tracks fossilized in Cretaceous-era lakeshore mud in what is now South Korea argue this week in Proceedings of the National Academy of Sciences that the dinosaur footprints are “indirect evidence of pre-avian aerial behavior” in a tiny microraptor.The tracks, which belong to a sparrow-sized theropod related to Tyrannosaurus rex, are spaced far enough apart to indicate that the tiny dino was moving across the mud very quickly. That speed, the researchers argue, is faster than the animal should have been able to go just by running with its hindlimbs. However, if flapping wings were added into the equation to give a power boost, the spacing might make sense.If the microraptor did, in fact, have flight-capable wings, that would mean that the ability to fly may have evolved in multiple lineages of dinosaurs, not just the descendants of Archaeopteryx we see as modern birds. Other researchers are not convinced of the analysis, arguing that the tracks may not all have come from the same individual at the same time.Jason Dinh, climate editor for Atmos, joins guest host Sophie Bushswick to talk about the debate, and other stories from the week in science, including an archeological find of medieval-era Silk Road cities in the Uzbek mountains, breathing differences in people born with the inability to smell, and the surprising ability of hornets to hold their liquor.Biodiversity's Biggest Event Is Underway In ColombiaFrom now until November 1, bureaucrats from nearly every country in the world will be gathered in Cali, Colombia, for COP16, better known as the United Nations biodiversity summit.

This year's conference will take a temperature check on how nations are doing in their quest to meet this goal (spoiler alert: not well).Also on the agenda are the questions of who should profit from non-human DNA, and how a $700 billion funding gap for conservation work can be filled.

Samples of 2.5 billion-year-old mantle rocks found at spreading ocean ridges could put bounds on models of how the planet formed. And, researchers decreased the amount of lignin in poplar tree wood, making it stronger and slower to deteriorate.‘Time Capsule' Rocks Provide Clues About Earth's MantleIf you're looking to really learn about the history of our planet, look to geology. Ancient rocks can provide a time capsule of the conditions in which they formed. But even the geologic record has its limits—rocks and minerals get weathered, buried, heated, melted, and recycled over time—so geologists need to search out rare super-old geologic holdouts to tell about the earliest times.Writing in the journal Nature in July, researchers described what they can learn about the chemical history of Earth's mantle, the geologic layer beneath the planet's crust, from studying 2.5 billion-year-old rocks collected at spreading ocean ridges. They found that these unusual mantle rocks didn't necessarily have to have been formed in a world with less available oxygen, but could have been produced just by the mantle layer being hotter long ago.Dr. Elizabeth Cottrell, chair of the Department of Mineral Sciences at the Smithsonian's National Museum of Natural History, joins Ira to talk about the research and why a collection of old rocks is an important part of international scientific infrastructure.Genetically Engineering Stronger Poplar Tree WoodTrees play a big role in the fight against climate change: They can soak up carbon dioxide from the air and store it for centuries in the form of biomass. But it turns out that trees could be doing even more.In 2023, Science Friday covered how the company Living Carbon had genetically engineered poplar trees to have a more efficient photosynthesis process. This allowed the trees to grow twice as fast and store 30% more carbon biomass than regular poplars, making them ideal for the carbon credit market.Recently, researchers at the University of Maryland also experimented with genetically modifying poplar trees. But this time, they had a different goal in mind. They modified the tree to reduce the amount of lignin in its wood. This made the wood stronger without the need for harsh chemical processing. It also slowed the deterioration rate of the wood, which allows it to store carbon for longer periods.To explain more about this “super wood,” SciFri guest host Sophie Bushwick is joined by the lead plant geneticist on the study, Dr. Yiping Qi, associate professor at Department of Plant Science and Landscape Architecture at the University of Maryland.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Shark fishing is alive and well, but the fishermen who do it are increasingly prioritizing conservation. And, an unknown ant was spotted in Manhattan in 2011, and it quickly spread through New York City. We now know what it is.Fishing For—And Saving—Sharks off the Jersey ShoreAt an undisclosed beach at 5:30 p.m. in New Jersey, shark fisherman AJ Rotondella and two clients wait for beachgoers to leave. Once the beach is empty, Rotondella cuts up some chunks of fish as bait, and casts lines into the water.“I shark fish, shark fish, shark fish, eat pizza, and shark fish … that's pretty much it,” Rotondella said. “Waking up in the morning … wide open ocean, anything could be anywhere at any time. And I think that's fascinating. No matter how long you've done this, you've never seen it all.”He has always loved fishing, and got into shark fishing 13 years ago, when his brother told him they could catch sharks from the beach. They caught two on their first day and could not catch another shark for the rest of the year.“That really got me interested because I knew it was possible, but I couldn't do it again,” he said. “I … absolutely obsessed over this.”But Rotondella had a steep learning curve ahead of him. By trial and error, sometimes staying on a beach for multiple days, he learned how to read the tides, water temperatures, currents, and even phases of the moon to figure out how to track the sharks.Read the full story at sciencefriday.com.Scientists Identify The ‘ManhattAnt' Spreading Across NYCNew York City is home to more than 8 million people.

You might be familiar with a gigabyte, one of the most popular units of measure for computer storage. A two-hour movie is 3 gigabytes on average, while your phone can probably store 256 gigabytes.But did you know that your body also stores information in its own way?We see this in DNA, which has the instructions needed for an organism to develop, survive, and reproduce. In computing storage terms, each cell of our body contains about 1.5 gigabytes worth of data. And with about 30 trillion cells in our bodies, we could theoretically store about 45 trillion gigabytes—also known as 45 zettabytes—which is equivalent to about one fourth of all the data in the world today.Recently, a group of researchers was able to develop a technology that allows computer storage and processing using DNA's ability to store information by turning genetic code into binary code. This technology could have a major impact on the way we do computing and digital storage.To explain more about this technology, SciFri guest host Sophie Bushwick is joined by two professors from North Carolina State University's Department of Chemical and Biomolecular Engineering, Dr. Albert Keung and Dr. Orlin Velev.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Human cases of EEE have also been reported in Wisconsin, New Jersey, Massachusetts, and Vermont, causing some municipalities to step up mosquito control efforts or attempt to limit outdoor activities during peak mosquito times at dawn and dusk.Other mosquito-borne diseases are on the rise as well. Oropouche fever, a viral disease typically found in South America, has been spotted in the US—and in Brazil, health officials are reporting an 800% increase in the disease. Dengue fever, also spread by mosquitoes, has been increasing across Europe. Experts attribute all the surges to climate change, which has brought warmer, wetter weather that has allowed mosquito populations to thrive and expand their ranges.Sophie Bushwick of New Scientist joins guest host Rachel Feltman to talk about climate, mosquitoes, and disease, and how communities are trying to curb the spread.

An early study found that electrical stimulation could improve hand and arm function in people with spinal cord injuries. Also, for thousands of years, Indigenous communities in Guatemala have used observations and mathematics to track astronomical events.Zapping Nerves Into RegrowthResults of an early trial published this week in the journal Nature Medicine found that people with cervical spinal cord damage showed some improvements both in strength and movement in arm and hand function after they received electrical stimulation near the site of their injury. The improved function persisted even after the stimulation stopped, indicating that the treatment may be inducing nerve cells to regrow in the damaged area.Sophie Bushwick, senior news editor at New Scientist, joins Ira to talk about the work and what it could mean for people with severe spinal cord injuries.

Finding an atmosphere around a rocky planet is a big step for exoplanet exploration: Earth's atmosphere is crucial to its ability to sustain life, and astronomers need to be able to identify rocky planets that have atmospheres to search for life outside the solar system.However, 55 Cancri e is likely far too hot to have any life: Researchers estimate the surface temperature to be about 3,100 F, thanks to its close proximity to its sun and a probable magma ocean that envelops the planet. But this could also give clues to Earth's formation, as its own surface was also once covered by lava.Jason Dinh, climate editor at Atmos, joins guest host Sophie Bushwick to talk about this and other top news in science this week, including tightening restrictions on risky virus research in the US, possible evidence for a sperm whale “alphabet,” and how environmental changes are leading to an increase in disease in humans, animals, and plants.Boeing Plans To Fly Humans To The ISS Next WeekWhen NASA retired its space shuttle program in 2011, the agency had to find a new way to transport astronauts and supplies to the International Space Station (ISS).

A long-awaited rule from the EPA limits the amounts of six PFAS chemicals allowed in public drinking water supplies. Also, some spiders, beetles, and centipedes spend winter under snow in a layer called the subnivium. Plus, a drumroll for the total solar eclipse.EPA Sets Limits On ‘Forever Chemicals' In Drinking WaterThis week, the EPA finalized the first-ever national limits for the level of PFAS chemicals that are acceptable in drinking water supplies. Those so-called “forever chemicals,” per- and polyfluoroalkyl substances, have long been used in products like fire retardants and oil-and water-repellent coatings, and are now ubiquitous in the global environment. Water treatment plants will now have to test and treat for several varieties of the chemicals, which have been linked to a variety of health problems in people.Sophie Bushwick, senior news editor at New Scientist, joins SciFri producer Kathleen Davis to talk about the rule and its potential impact on water agencies.

How can some people recall random facts so easily? It may have to do with what else they remember about the moment they learned the information. Also, in Kenya, an invading ant species pushed out ants that protected acacia trees. That had cascading effects for elephants, zebras, lions, and buffalo.A ‘Jeopardy!' Winner Studied How Trivia Experts Recall FactsWhen contestants play “Jeopardy!,” it can be amazing to see how quickly they seem to recall even the most random, obscure facts. One multi-time “Jeopardy!” contestant, Dr. Monica Thieu, noticed something interesting about the way that she and her fellow contestants were recalling tidbits of information. They weren't just remembering the facts, but also the context of how they learned them: where they were, what they read, who they were with. Hypothesizing that for trivia superstars, information was strongly tied to the experience of learning it, she put that anecdotal evidence to the test. The results of her research were recently published in the journal Psychonomic Bulletin & Review.SciFri producer Kathleen Davis talks with Dr. Thieu, a psychology researcher at Emory University, and Dr. Mariam Aly, assistant professor of psychology at Columbia University, and a co-author of the new study. They discuss the psychology of trivia, how to get better at it, and why some people seem to be much more adept at recalling fun trivia facts than others.See if you can beat a "Jeopardy!" champ on our website!How One Invading Ant Species Sent Ripples Through A Food WebWhen people talk about the interconnectedness of nature, the usual example involves a little fish that eats a bug, a bigger fish that eats the little fish, and an even bigger fish at the top of the chain. But in reality, the interconnected relationships in an ecosystem can be a lot more complicated. That was certainly the case in a recent study, published in the journal Science, which describes how the arrival of an invasive ant species changed the number of zebras that get eaten by lions on the Kenyan savannah.The unwelcome ant is known as the big-headed ant. It's on a list of top 100 invasive species around the world. When it arrived on the African savannah, the ant newcomer muscled out a native ant species known as the acacia ant—which, though tiny, was able to help defend acacia trees from being grazed upon by elephants (picture getting a trunkful of angry ants while snacking).With the trees undefended, hungry elephants feasted, resulting in fewer trees on the savannah and more open space. That made the hunting environment less favorable to stealthy lions, and more favorable to fleet-footed zebras. But to the surprise of the researchers involved with the study, that didn't mean hungrier lions. Instead, the lions shifted their hunting from targeting zebras to targeting buffalo instead.Dr. Jacob Goheen and Douglas Kamaru of the University of Wyoming join guest host Sophie Bushwick to describe their research, and how a small ant can have a big effect on an ecosystem.Transcripts for each segment will be available after the show airs on sciencefriday.com.

#232During pregnancy the brain undergoes profound changes – almost every part of the cortex thins out and loses volume by the third trimester. It's such a big change that you can tell if someone's pregnant just by looking at a scan of their brain. How researchers discovered these changes and why they might be occurring.A massive, ancient group of cities has been discovered in the Amazon rainforest using lasers. It's the biggest pre-Columbian urban area ever found in the Amazon and parts of it date back further than any other settlement too. So why have we only just found it and why was it abandoned?Where does stuff go when it's sucked into a black hole? Based on Stephen Hawking's theory that black holes slowly evaporate, most of it just disappears. But in physics, information about that matter can't just disappear – so what's going on? Many teams have tried to solve this paradox, but an intriguing new idea may bring us closer to an answer. Once we develop a whole range of groundbreaking new spacecraft technology, that is.Every single year, hammer corals change their sex, swapping between male and female. While many animals, including corals, change their sex across their lifetimes, this clockwork, routine schedule is quite unusual. But it turns out a habit of change might be useful to help ensure successful reproduction in the ocean. Plus: Making lithium-ion batteries with 70 per cent less lithium – with help from AI; staving off the amphibian apocalypse with fungus-resistant frogs; and the discovery of the oldest known fossil skin.Hosts Timothy Revell and Christie Taylor discuss with guests Alex Wilkins, Grace Wade, Michael Le Page and Sophie Bushwick.

The Top Science News Stories of 2023As the year comes to a close, we wanted to reflect on some of the top science stories of 2023: Scientific breakthroughs that will shape our lives in 2024 and beyond. Research that's shifted how we understand the universe. And even a story or two that put a smile on our faces.In 2020, the story of the year was the rapid development of COVID-19 vaccines. And while there are now updated versions of those, vaccine development has gone much further. This year we saw approval of two exciting new vaccines, for RSV and malaria.SciFri's director and senior producer Charles Berquist talks with Sophie Bushwick, incoming senior news editor at New Scientist about this years vaccine breakthroughs and other top science news of the year, including a new generation of weight loss drugs, record high temperatures, completion of the human pangenome, an asteroid sample's arrival on Earth, ripples in space-time, AI to understand pets' emotions and T. rex's new smile.Solar Panels In Historic Cape Cod: Who Decides Where ‘Modern' Fits?Cape Cod is home to one of the largest historic districts in the country. In the 80 square miles that make up the Old Kings Highway Historic District, the goal of preservationists is to maintain a certain look. So from Sandwich to Orleans, some 45,000 people who live north of Route 6 are required to get approval from local historic committees for solar installations that are visible from a public way. Over the last few decades, many property owners who've had their solar plans challenged or denied have described the committees' decisions as inconsistent, arbitrary, and subjective.But the committees remain steadfast: tourists and locals alike love seeing historic buildings preserved. And solar panels on the front of a house can read like billboards for modernity.“When you start messing with the street view of your house, we have a legal right, on behalf of the public, to make a judgment of the appropriateness of it,” said Jim Wilson, administrative counsel for the Old Kings Highway Regional Historic District Committee, which sets standards and hears appeals of rulings by town committees.The preservationists' mandate is only to approve solar panels on homes when they present a minimal visual impact on the neighborhood. And that standard is often the source of the argument: what defines a minimum visual impact?Read the full story at sciencefriday.comTranscripts for each segment will be available after the show airs on sciencefriday.com.

A new ESA telescope could help us understand how dark matter and dark energy influence the structure of the universe. Also, using both JWST and the Chandra Observatory, astronomers discover the oldest known black hole.Euclid Telescope's First Images UnveiledThis week, the European Space Agency unveiled the Euclid space telescope's first full-color images of the cosmos. The telescope has a wide field of view and is designed to take images of large swaths of the sky in both visible and infrared light. The telescope's designers hope that they will be able to create a detailed 3D map of the cosmos over the next six years and, with that map, begin to sort out the influences of dark matter and dark energy on the basic structure of the universe.Sophie Bushwick, technology editor at Scientific American, joins Ira to talk about the first images from the Euclid telescope and other stories from the week in science. They'll try to explain the recent conversation about ultraprocessed foods and discuss steps toward regulating AI coming from the Biden administration and a host of other countries; a move to rename some North American birds; and the tale of a fish that uses electrolocation and some shimmies to get a 3D map of its environment.Not Just Dying Stars: A Black Hole That Came From GasThis week, astronomers confirmed that they had found the oldest known black hole, thanks to the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory. The supermassive black hole formed when the universe was still a toddler, just 470 million years after the Big Bang. But its age isn't the only thing that makes it unusual.Astronomers long thought that the only way a black hole could form was through the collapse of a star. But this week's discovery confirms a theory that some black holes at this early stage in the universe formed from the condensation of clouds of gas. The theory purports that such black holes would produce superheated x-ray-emitting gas. Now, data from JWST and Chandra have helped confirm these x-ray signals from the newly discovered black hole. The findings are available via preprint and have been published in the journal Nature Astronomy.Ira sits down with Dr. Priyamvada Natarajan, a professor of astronomy and physics at Yale who helped develop this theory, to talk about how these unique black holes change our understanding of the early universe.To stay updated on all things science, sign up for Science Friday's newsletters.

After 7 Years, NASA Gets Its Asteroid SampleAbout a week ago, space nerds got the delivery of a lifetime: a sample from Bennu, an asteroid soaring through the galaxy, currently about 200 million miles away. The capsule of rocks and dust came courtesy of NASA's OSIRIS-REx, the first U.S. mission to collect a sample from an asteroid.Scientists hope it'll help unveil some of the mysteries of our universe, like how the sun and planets came to exist or how life began. Guest host and musician Dessa talks with Sophie Bushwick, technology editor at Scientific American, about this week in science. They also chat about how antimatter interacts with gravity, the new RSV vaccine for pregnant people, why LED streetlights are turning purple, and how beetles came to dominate all other species, especially ants. How You See With Your BrainEver try to take a picture of a spectacular moon that looks like it fills up half the sky? And then you look at the photo, and the moon looks like a tiny dumb ping-pong ball? And you want to march into the Apple store and demand to know why this pocket-size device fails to capture the wonder of the cosmos properly? The majesty of that supermoon you saw might be in your head as much as it is in the sky—your brain does a lot more than just receive data reports from your eyes. Vision is complicated. Seeing involves a lot of interpretation, of which you're usually unaware. Guest host and musician Dessa talks with neuroscientist Dr. Cheryl Olman, associate professor in the University of Minnesota's psychology department, about her work to better understand how the brain processes visual information using sophisticated fMRI techniques, including studying the brains of people with schizophrenia. Are Jellyfish Smarter Than We Think?Jellyfish are known for their graceful, hypnotic movement through the water—and for occasionally stinging swimmers. One thing they're not known for, however, is intelligence. A study published in the journal Current Biology, however, challenges the idea of the ‘brainless' jellyfish by showing that at least one species of jelly may be capable of associative learning.The scientists were studying the Caribbean box jellyfish, which normally lives amongst a forest of tangled mangrove tree roots. In the lab, they painted false roots on the walls of the jellyfish's tank, and watched to see what happened. At first, the jellies judged the low-contrast gray roots to be far away, and tried to swim through them. After a few collisions with the tank, however, the jellies learned that the false roots were closer than they appeared, and learned to keep their distance.Dr. Anders Garm, an associate professor of marine biology at the University of Copenhagen in Denmark, joins guest host Dessa to explain the experiment, and what it tells researchers about the connection between the behavior of small groups of neurons and the process of learning. The Mysteries Of Freshwater JellyfishIn 1933, a high schooler fishing along the Huron River in Ann Arbor, Michigan looked into the water and saw something weird. It turned out to be a freshwater jellyfish – the first ever discovered in the Great Lakes region. Later that year, there was another sighting in Lake Erie.Researchers think the species hitched a ride here on aquatic plants shipped from China, then spread. But there's no evidence they harm the lake ecosystems they now call home.Since then, the jellyfish have spread across the Upper Midwest, loitering mostly in inland lakes, rivers, and streams. But we still don't know all that much about them.A biology professor and her field research class at Eastern Michigan University are hoping to change that. Every week, they slap on masks, snorkels, and floaties, and wade out into a southeast Michigan lake on the lookout for jellyfish.Read the rest at sciencefriday.com. To stay updated on all-things-science, sign up for Science Friday's newsletters.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Researchers in South Korea say they've discovered a room-temperature, ambient-pressure superconductor. If it works, it would create electricity under normal, everyday conditions. But some scientists are hesitant to applaud this purported breakthrough. This field has a long history of supposed breakthroughs, many of which turn out to be not so superconducting after all. In other science news, NASA has detected a ‘heartbeat' from the Voyager 2 spacecraft, which lost contact last month. This may allow scientists to reestablish contact with the spacecraft before its expected October 15 date. Joining Ira to talk about these stories and more is Sophie Bushwick, technology editor for Scientific American, based in New York, New York.   How Oppenheimer's Bombs Compare To Today's Nukes On the day the film Oppenheimer came out, Science Friday discussed the history of the Manhattan Project, including the legacy of the Trinity Test, where the world's very first nuclear weapon was detonated in the desert of New Mexico. We also heard from a survivor of the Hiroshima bombing and a New Mexican downwinder. But our listeners responded with even more questions that we couldn't get to—including this, from Randy in Orlando, who wrote, “I've heard Neil deGrasse Tyson say the new bombs aren't that dirty?” Randy's referring to the astrophysicist's interview last November, in which he said: “Modern nukes don't have the radiation problem … it's a different kind of weapon than Hiroshima and Nagasaki.” We wanted an answer to this question—and others—about current nuclear weapons technology, an issue that Russia's implied threats of using nuclear weapons against Ukraine also raise. Ira talks with Dr. Zia Mian, a physicist and co-director of Princeton's Program on Science and Global Security, about how nuclear weapons technology has evolved over the last 80 years, how many there are, and the new threats they pose.   From Splenda to Aspartame: Are the Artificial Sweeteners We Use Hurting Us? The World Health Organization recently classified aspartame as a “possible carcinogen.” While the designation may seem scary, it simply indicates that the agency cannot rule out that the substance causes cancer.

Ira breaks down the science behind that decision, what we know about the health effects of artificial sweeteners, and takes listener calls with guests Marji McCullough, senior scientific director of epidemiology research at the American Cancer Society and Dr. Walter Willett, professor of epidemiology and nutrition at the Harvard T.H.

Orcas Are Attacking Boats Near Spain. Scientists Don't Know Why This Thursday, the Supreme Court restricted the scope of the Clean Water Act pertaining to wetlands, in a 5-4 vote. This could affect the Environmental Protection Agency's power to protect certain kinds of wetlands, which help reduce the impacts of flooding by absorbing water, and also act as natural filters that make drinking water cleaner. Justice Brett Kavanaugh joined the court's three liberal members in the dissent, writing that the decision will have, “significant repercussions for water quality and flood control throughout the United States.” Plus, earlier this month, three orcas attacked a boat, leading to its sinking. This is the third time an incident like this has happened in the past three years, accompanied by a large rise of orcas attacking boats near the Strait of Gibraltar. Scientists are unsure of the cause. One theory is that these attacks could be a fad, led by juvenile orcas in the area, a documented behavior in this subpopulation of the dolphin family. They could also be a response to a potential bad encounter between boats and orcas in the area. Science Friday's Charles Bergquist talks with Sophie Bushwick, technology editor for Scientific American, about these and other stories from this week in science news, including a preview of a hot El Niño summer, an amateur astronomer who discovered a new supernova, and alleviating waste problems by using recycled diapers in concrete.     A Famous Sled Dog's Genome Holds Evolutionary Surprises Do you remember the story of Balto? In 1925, the town of Nome, Alaska, was facing a diphtheria outbreak. Balto was a sled dog and a very good boy who helped deliver life-saving medicine to the people in the town. Balto's twisty tale has been told many times, including in a 1990s animated movie in which Kevin Bacon voiced the iconic dog. But last month, scientists uncovered a new side of Balto. They sequenced his genes and discovered the sled dog wasn't exactly who they expected. The study published in the journal Science, was part of a project called Zoonomia, which aims to better understand the evolution of mammals, including our own genome, by looking at the genes of other animals—from narwhals to aardvarks. Guest host Flora Lichtman talks with Dr. Elinor Karlsson, associate professor in Bioinformatics and Integrative Biology at the UMass Chan Medical School and director of Vertebrate Genomics at the Broad Institute of MIT and Harvard; Dr. Katie Moon, post-doctoral researcher who led Balto's study; and Dr. Beth Shapiro, professor of ecology and evolutionary biology at UC Santa Cruz, who coauthored the new study on Balto and another paper which identified animals that are most likely to face extinction.     The Long And Short Of Telomere Activity Telomeres are repeating short sequences of genetic code (in humans, TTAGGG) located on the ends of chromosomes. They act as a buffer during the cell replication process. Loops at the end of the telomere prevent chromosomes from getting inadvertently stuck together by DNA repair enzymes. Over the lifetime of the cell, the telomeres become shorter and shorter with each cell division. When they become too short, the cell dies. Telomere sequences weren't thought to do much else—sort of like the plastic tip at the end of a shoelace. Writing in the Proceedings of the National Academy of Sciences, researchers now argue that telomeres may actually encode for two short proteins. Normally, those proteins aren't released into the cell. However, if the telomere is damaged—or as it gets shorter during repeated cell replication cycles—those signaling proteins may be able to leak out into the cell and affect other processes, perhaps altering nucleic acid metabolism and protein synthesis, or triggering cellular inflammation. Jack Griffith, one of the authors of the report and the Kenan Distinguished Professor of microbiology and immunology at the UNC School of Medicine, joins SciFri's Charles Bergquist to talk about the idea and what other secrets may lie inside the telomere.   Philadelphia's Mütter Museum Takes Down Digital Resources Robert Pendarvis gave his heart to Philadelphia's Mütter Museum.

Pendarvis thought his original heart could tell an important story, and teach others about this rare condition, which is why he was determined to put it on display at the Mütter Museum. The Mütter Museum is a Philadelphia institution, a medical museum that draws hundreds of thousands of visitors to its rooms filled with anatomical specimens, models, and old medical instruments.

Why Do Humans Anthropomorphize AI? Artificial intelligence has become more sophisticated in a short period of time. Even though we may understand that when ChatGPT spits out a response, there's no human behind the screen, we can't help but anthropomorphize—imagining that the AI has a personality, thoughts, or feelings. How exactly should we understand the bond between humans and artificial intelligence? Guest host Sophie Bushwick talks to Dr. David Gunkel, professor of media studies at Northern Illinois University, to explore the ways in which humans and artificial intelligence form emotional connections.   A Bee's Eye View Of Cities' Microbiomes When you want to look at the microbial health of a city, there are a variety of ways to go about it. You might look at medical records, or air quality. In recent years, samples of wastewater have been used to track COVID outbreaks. Studies of urban subway systems have involved painstaking swabs of patches of subway muck. But now, researchers are offering another approach to sample a city's environment—its beehives. A report recently published in the journal Environmental Microbiome used the bees foraging in a city to provide information about the town's bacteria and fungi. The researchers found that by looking at the debris in the bottom of a beehive, they could learn about some of the environments in the blocks around the hives. The microbes they collected weren't just species associated with flowers and plant life, but included organisms associated with ponds and dogs. The team found that the hive samples could reveal changes from one neighborhood to another in a city, and in the microbial differences between different cities—samples taken in Venice, for instance, contained signals associated with rotting wood that were not seen in samples from Tokyo. Elizabeth Henaff, an assistant professor in the NYU Tandon School of Engineering at New York University and a co-author of the report, joins SciFri's Kathleen Davis to talk about what bees and microbes can tell us about the cities we share.   This Is Your Brain On Words What happens after you pick up a book, or pull up some text on your phone? What occurs between the written words hitting your eyes and your brain understanding what they represent? Scientists are trying to better understand how the brain processes written information—and how a primate brain that evolved to make sense of twisty branches and forking streams adapted to comprehend a written alphabet. Researchers used electrodes implanted in the brains of patients being evaluated for epilepsy treatment to study what parts of the brain were involved when those patients read words and sentences. They found that two different parts of the brain are activated, and interact in different ways when you read a simple list of unrelated words, compared to when you encounter a series of words that builds up a more complex idea. Dr. Nitin Tandon, a professor of neurosurgery at UTHealth Houston and one of the authors of a report on the work published in the Proceedings of the National Academy of Sciences, joins guest host Sophie Bushwick to talk about the study, and what scientists are learning about how the brain allows us to read.   Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Despite Superconductor Breakthrough, Some Scientists Remain Skeptical This week, researchers unveiled a new superconductor which they say works at room temperature. Scientists have been working on identifying new superconductors for decades—materials that can transmit electricity without friction-like resistance. However, previously discovered superconductors only work at super cold temperatures, and under incredibly high pressures. The newly discovered superconductor, lutetium, could be much more useful in applications, like strong magnets used in MRIs, magnetically floating trains, and even nuclear fusion, than those which must be kept super-cold. But there's a bit of a wrinkle. The research team which published their results in the journal Nature this week, had their previous study on another superconductor retracted in 2020. As a result, many scientists in the field have concerns about the quality of this new research Ira talks with Sophie Bushwick, technology editor at Scientific American, to make sense of this superconductor saga and other big science news of the week including bumblebee culture, extreme ways to save mountain glaciers, and identifying the worms in Mezcal. Can Utah's Great Salt Lake Be Saved Before It's Too Late? Utah's Great Salt Lake is one of the state's treasures and is vital to the local ecosystem and economy. But since the 1980s, it's been drying up—and now the lake's water level is at a record low. The lake is fed by three rivers, which are fed by Utah's snowpack. It's also a terminal lake, meaning that there's no outlet for water to exit. And as the population of Utah has increased, more water has been diverted from those rivers to agriculture, industry, and local residents. As more of the lakebed has become exposed, wind has picked up dust plumes and blown them into local communities. Dr. Kevin Perry, a professor of atmospheric science sciences at the University of Utah, discovered that those lakebed dust plumes contain heavy metals, including arsenic. But despite these challenges, Perry and local politicians are confident that if the right water usage reductions are put in place, the lake will have a chance to bounce back. Science Friday digital producer Emma Gometz visited Perry at the Great Salt Lake in January, who describes how we got here and what the future holds. Exploring A New Theory About Dark Energy's Origins Black holes remain one of the great mysteries of the universe. Another enigma? Dark energy. Little is known about this concept, aside from the belief that dark energy accelerates the expansion of the universe. These are two of the most mind-bending concepts in physics. There's a new theory that brings together black holes and dark energy into one mind-bending solution: research led by the University of Hawai'i at Manoa posits that dark energy could actually come from supermassive black holes at the center of galaxies. If true, this would be a massive breakthrough in what we know about astrophysics. But many experts in the field have reservations about this idea. Two of those experts join Ira to talk about this theory, and other recent black hole breakthroughs: Janna Levin, PhD, author of “Black Hole Blues” and “Black Hole Survival Guide,” and a physics and astronomy professor at Barnard College in New York City, and Feryal Özel, a professor and chair of physics at Georgia Institute of Technology, in Atlanta, Georgia.

The prevailing theory was that ancient peoples traveled from Siberia to modern-day Alaska using the Bering strait as a land bridge. But new genomic research, published in Current Biology, reveals movement in the opposite direction, back to Asia, as well. Ira talks with Sophie Bushwick, technology editor at Scientific American, about the new research, and other top science stories of the week, including a new AI voice generator, a green comet visible visit in the night sky for the first time in 50,000 years, and how a specific atmospheric weather pattern caused historic flooding in California. Lab-Grown Meats Are Finally Inching Closer To Commercial The United States is one of the largest consumers of meat in the world, with the average American eating 273 pounds of meat per year That's not to say that tastes aren't changing: Nearly a quarter of Americans say they have cut down on meat consumption, and 41% of Americans under 50 have tried plant-based meat. There's been a wave of companies and academic institutions working on cellular agriculture—a fancy way of saying animal products grown from cells in labs, and not from a meat farm. While lab-grown meat is not available in grocery stores yet, the FDA gave approval to make meat from animal cell culture for the first time in November. Upside Foods, the company making the product, makes chicken from cells grown in tanks. Joining Ira to talk about cell agriculture are Andrew Stout, cellular agriculture biologist based in Boston, Massachusetts, and Aryé Elfenbein, co-founder of Wildtype, based in San Francisco, California, a company working on growing seafood from cells.

There Are Now Eight Billion People On Earth. What's Next? Humankind just hit a big milestone this week: a world population of eight billion people. A hundred years ago, there were less than two billion, and now we've more than quadrupled that. But after decades of quick population growth, what will the next few decades hold? Sophie Bushwick, technology editor at Scientific American, explains this to Ira live from the studio. They also talk about other science news this week, like a new initiative from COP 27 to help transition poor countries away from fossil fuels, an ambitious plan to put solar panels in space, how mental health apps aren't protecting user data, what the discovery of the earliest cooked meal in history tells us about human evolution, and the very first lab-grown meat to gain FDA approval.   Groundwater Contamination In Springfield, Missouri Kept Secret From Residents Early in 2019, Ed Galbraith faced a crowd of some 200 unhappy Springfield, Missouri residents. He wanted to make amends. Galbraith, then director of Missouri Department of Natural Resources' environmental quality division, acknowledged that the state agency in charge of protecting the environment should have announced sooner that contaminated water had spread from an old industrial site near the Springfield-Branson National Airport. Residents had recently found out that a harmful chemical known to cause cancer had been detected in the groundwater. The contamination came from the site of the now-shuttered Litton Systems, a former defense contractor that had employed thousands of people in Springfield to make circuit boards for the Navy and telecommunications industry.

He renamed it Meta, short for “metaverse.” And he promised the company would go all in on building a virtual reality world like the first famous metaverse—the fictional topic of Neal Stephenson's 1992 novel “Snow Crash.” While many companies have tried to make metaverses in the 30 years since “Snow Crash” came out, including the popular virtual world called Second Life, we seem to be entering a new era of metaverse hype: besides Zuckerberg, Apple seems to be investing in a VR world. And even Nike wants to make a metaverse. So what are users actually getting if these companies succeed at their goals? And are there other, perhaps better, ways to go about bringing people together virtually? Ira talks to science fiction writer and tech journalist Annalee Newitz, and Avi Bar-Zeev, a pioneer of extended-reality technologies for companies like Disney, Apple, and others.

Hurricane Ian Destroys Iconic Florida House Meant To Survive Hurricanes The Cape Romano Dome House, built in 1982, was an iconic—if more recently unsightly—piece of Florida architecture. The six interconnected domes located in Collier County, Florida, were built to be hurricane resistant and self-sustaining, with solar power, rainwater harvesting, and other innovations. However, erosion and rising sea levels had put the structure at risk, with the structure's foundation pillars being completely underwater by 2009. Last week's Hurricane Ian finally destroyed the structure. Sophie Bushwick, technology editor at Scientific American, joins Ira to talk about the symbolic loss of the building and other stories from the week in science. They discuss possible approaches to repair the damaged Nord Stream gas pipeline, the finding that certain cancerous tumors contain their own microbiomes of bacteria and fungi, and the delicate process of interpreting the behavioral cues of your feline friends.   How States Are Planning To Power The Electric Vehicle Boom California and New York recently adopted regulations which ban sales of new gas-powered vehicles by 2035. Several other states are likely to quickly follow suit. But the uptick in vehicle demand will also require new infrastructure, and increase demand for mining metals used to produce car batteries. Jessika Trancik, professor at the Institute for Data, Systems and Society at Massachusetts Institute of Technology, and David Reichmuth, senior engineer for the Union of Concerned Scientists' Clean Transportation Program, join Ira Flatow to discuss the future of electric vehicles. Plus, Eric Gebhardt, chief technology officer at Wabtec, an industrial locomotive company, discusses the challenges and promise of battery-electric trains.

California Accelerates Its Push For Electric Cars This week, air pollution regulators in California voted to phase out sales of new gasoline-powered vehicles, with a complete ban on gas car sales by 2035. The decision could have a larger impact on the automobile industry, however, as many states choose to follow California's lead with regard to air quality and emissions decisions. Sophie Bushwick, technology editor at Scientific American, joins guest host Roxanne Khamsi to help unpack the decision. They also discuss some of the other science stories from this week, including a survey-based study showing that Americans really do care about climate change and support mitigation measures, a look at how sugar substitutes can change the microbiome, and an engineer's advice for how to build the sturdiest sandcastles.   Meet Two Autistic Researchers Changing How Autism Research Is Done For many decades, autistic people have been defined by non-autistic people, including in science. Since the very beginning of research about autistic people, neurotypical scientists and institutions have been at the helm. The field has largely been defined by what neurotypical researchers are curious about learning, instead of prioritizing research that the autistic community asks for. Because of that, and the invisibility of autistic adults in our society, a large chunk of this research has neglected the needs of autistic people. In many cases, it's caused harm to the very people the research aims to help. Until recently, there have been very few openly autistic researchers who study autism. But there is a growing body of openly autistic scientists who are using both their expertise and their own lived experiences to help shape the future of autism research. Guest host Roxanne Khamsi speaks with Dr. TC Waisman, a leadership coach and researcher studying autism and higher education, based in Vancouver, British Columbia, and Patrick Dwyer, a Ph.D. candidate studying sensory processing and attention in autism at the University of California, Davis. They talk about the history of autism research, why the inclusion of autistic people in research leads to more helpful outcomes, and how they see the future of autism research changing. Ira Kraemer consulted on this story.   Ecological Data From Deep In The Pantry Most people wouldn't be excited by a call offering a basement full of canned salmon dating back to the 1970s. But for researchers trying to establish baselines for what's normal and what's not when it comes to aquatic parasite populations, the archive of fishy tins, maintained by the Seattle-area Seafood Products Association, was a valuable resource. Natalie Mastick and colleagues combed through the tins with tweezers, counting the numbers of parasitic anisakid worms they found. (Since the salmon was cooked, the worms—though gross—posed no risk to human eaters.) The team found that in their samples of chum and pink salmon, the incidence of parasitic infection increased over the 40 years covered by the salmon archive. The finding might be good news—an increase in the numbers of marine mammals in the area, key hosts for the parasites, could be responsible for the wormy increase. Natalie Mastick, a PhD candidate in the University of Washington's School of Aquatic and Fishery Sciences, joins guest host Roxanne Khamsi to explain the study.   Medieval Friars' Farming May Have Caused Tummy Troubles What was life like back in medieval England? You might think that the learned friars who lived in the town of Cambridge—scholars, with access to innovations like latrines and places to wash their hands—might have lived healthier lives than the common folk. But a recent study published in the International Journal of Paleopathology says that, at least when it comes to intestinal parasites, the friars may have been worse off. Dr. Piers Mitchell runs the Cambridge Ancient Parasites Laboratory and is a senior research associate in the McDonald Institute for Archaeological Research. Mitchell and colleagues excavated soil samples from around the pelvises of medieval skeletons in one Cambridge cemetery, then examined the soil microscopically looking for parasite eggs. They found that friars in the cemetery had almost twice the incidence of intestinal parasites as commoners in the town—a fact they speculate could be related to friars using human feces, from the friary latrine, to fertilize the gardens. Mitchell joins guest host Roxanne Khamsi to explain the study.   Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

For The Love Of Volcanoes A new documentary, “Fire of Love,” tells the story of French volcanologists Katia and Maurice Krafft. The married couple spent two decades chasing volcanic eruptions across the world. Katia was a geochemist and Maurice a geologist. Together, they studied the science of volcanoes and produced films showcasing their power. That is, until their deaths in 1991, when they were killed by the very thing they loved so much. Guest host Sophie Bushwick talks with Sara Dosa, director of the documentary “Fire of Love,” which is in theaters nationwide, and will be available on Disney+ later this year.   A Blind Researcher Making A More Accessible World Joshua Miele has spent his career trying to make the world more accessible for blind and visually impaired people. As a blind person, his lived experiences have shaped the way he thinks about technology and how it can be used to better serve disabled people. He's invented products like YouDescribe—a tool that adds audio description to YouTube videos—and Tactile Maps Automated Production, a software that creates tactile maps for people to feel. Although adaptive technologies try to help disabled people access information, it isn't always driven by the input and needs of disabled people. There needs to be more disabled designers, engineers, and researchers spearheading this work, Miele says. Now, he works as a principal accessibility researcher at Amazon's Lab126, where he helps make products like the Echo and Fire tablets more accessible. Guest host Sophie Bushwick speaks with Miele about how his own experiences shape his work, and the importance of disability inclusion in designing new technologies.   What You Might Not Have Known About The Vagina When it comes to researching human genitals and the organs called, in simple terms, “reproductive,” the penis has long been the star of the show. “It doesn't help to only look at one or the other. Only by zooming out can we see them in their full range of variation and possibility,” writes science journalist Rachel E. Gross in her book, Vagina Obscura: An Anatomical Voyage, which tells the long history of neglected research into the vagina and its companion organs—the uterus, clitoris, Fallopian tubes, and ovaries. The book takes readers through myths, mysteries, and the legacy of shame around sexuality. It also introduces researchers who are finally making breakthroughs in our understanding of fertility, pleasure, and even immune health that's been linked to these organs. The book interviews doctors who are using that knowledge to make life better for everyone—including cancer patients and older people going through menopause, transgender women who want their own vaginas, people with endometriosis, and those, including intersex people, looking to regain pleasure and agency after childhood genital cutting. Producer Christie Taylor interviews Gross about our growing understanding of clitoral anatomy, the long-misunderstood egg cell, the uterus' ability to heal, and more.

Decades Of Alzheimer's Research Could Be Based On Fraudulent Data Alzheimer's disease is a devastating brain disorder that slowly affects memory and thinking skills. For many people who worry that loved ones may succumb to this disorder, the possibility of research in the field of Alzheimer's is a balm of hope. However, a massive report from Science Magazine highlights a startling discovery: that decades of Alzheimer's research are likely based on faulty data. Alzheimer's researchers are grappling with the revelation, and what it means for future research of the disease. In other science news of the week, scientists have identified pits on the moon that are a comfortable temperature: averaging 63 degrees Fahrenheit. But don't plan that space vacation yet—research finds that air pollution from space-bound rockets has an exorbitantly high effect on global warming—much more than traditional airplane travel. Joining guest host Sophie Bushwick to discuss these stories is Maggie Koerth, science writer for FiveThirtyEight based in Minneapolis, Minnesota. They also discuss how childhood vaccinations have dropped dramatically during the COVID pandemic, and why this is likely tied to New York's first Polio case in nearly a decade.    Higher Temperatures Are Bad For The Body Across the globe, hundreds of millions of people have been dealing with extreme heat. The three most populated countries in the world—China, India and the United States—have been gripped by heat waves throughout the summer. Extreme heat isn't just uncomfortable: it can be deadly, putting strain on the organs and systems that keep us in equilibrium. Heat is especially dangerous for vulnerable populations such as the elderly, pregnant people, and those without access to air conditioning. In the United States, heat is responsible for more deaths than any other type of weather event. Joining guest host Sophie Bushwick to talk about what high temperatures do to the body, and how we can protect our health and safety in a heat wave is Chris Uejio, associate professor of public health at Florida State University in Tallahassee, Florida.    Protecting Piping Plovers Isn't A Walk On The Beach July is nearly through, and so is the piping plover's nesting season. It's make-or-break time for these small, endangered shorebirds. There are roughly 8,000 piping plovers in the entire world. To put that in context, birders often get really excited to see a rare bird like a snowy owl. But there are about 28,000 snowy owls in the world, three times the number of piping plovers.  Since piping plovers make their nests along the water and out in the open, their chicks are very vulnerable to being gobbled up by predators. And a major reason for their decline in numbers is human development along the beaches, lakes, and rivers where piping plovers lay their eggs.  SciFri radio producer Shoshannah Buxbaum went out to Fort Tilden in Queens, NY to report on a volunteer-run conservation effort along the New York City coastline. And later in the segment, Michigan radio reporter Lester Graham talks with guest host Sophie Bushwick about the unique challenges and triumphs of the piping plovers who nest along the Great Lakes.   This Glove Takes Inspiration From An Octopus' Arm Octopuses have more than 2,000 suckers on eight arms, and each one is controlled individually, making these critters incredibly dextrous. So when a team of researchers wondered how to design a glove that could hold onto slippery objects underwater, they turned to octopuses for inspiration. Ultimately, they created something they're calling an octa-glove. Guest host Sophie Bushwick talks with Michael Bartlett, an assistant professor of mechanical engineering at Virginia Tech, about his team's engineering, and what they learned from the ambidextrous creatures.   Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Scientists Found The Biggest Known Plant On Earth This week, an underwater seagrass meadow claimed the title for the world's largest plant. This organism sprawls across 77 square miles of shallow ocean and has survived 4,500 years. To accomplish this, it kept cloning itself and created identical offshoots to spread along the sand. The ocean has changed wildly over the last 4,500 years, yet this plant has survived. Researchers believe that cloning itself may have helped the plant adapt to a changing ocean, offering hope that seagrass meadows may be more resilient than expected in the face of climate change. Sophie Bushwick, a technology editor at Scientific American, joins Ira to talk about how this mighty meadow persisted for millennia and what it tells scientists about climate change. Sophie and Ira also discuss other stories from this week in science, including what countries are most responsible for fueling the extinction of wildlife, what a well-preserved fossil tell us about the sex lives of ancient trilobites, why male mice are terrified of bananas, the creation of a flea-sized robot that walks like a crab, and how scientists developed an algorithm to pinpoint the whereabouts of unknown asteroids.   Building A Better Battery… Using Plastic? The lithium-ion battery in your cell phone, laptop, or electric car is a crucial component of the modern world. These batteries can charge quickly, and pack a lot of power into a small space. But they're also expensive, require mining scarce lithium, and need to be handled carefully. Other battery technologies have issues as well. For example, the heavy lead-acid battery that starts your car is quite reliable—but lead has its own environmental and health costs. That's why PolyJoule, a startup company based near Boston, is trying to create a new kind of battery, somewhere on the performance curve between those old lead-acid batteries and lithium-ion cells. Their technology relies not on a metal, but on polymer plastics.

So what would happen if you tweaked their smell so that humans smell really gross to them? That's what Dr. Chris Potter and his lab recently tried to do—they changed the neurons responsible for the insect's smell detection, so that in the presence of animal odors, their olfactory systems would be overwhelmed. Instead of smelling like a nice meal, mosquitoes would be repelled by the scent of humans, like if you were stuck in a small room with someone wearing too much cologne. This method worked in Drosophila, the common fruit fly, so Potter and his team were hopeful that would also be the case for mosquitoes. Instead, the experiment didn't go as planned. Because finding a blood meal is so important for mosquitoes, those little buggers evolved backups for their backup receptors. When Potter turned one pathway off, another one kicked in. Ira talks with Dr. Chris Potter, an associate professor of neuroscience in the Johns Hopkins University School of Medicine, based in Baltimore, Maryland, about his findings, and why we can never quite get mosquitoes to bug off.   So You Think You Know About Sex When it comes to sex, there's really no such thing as normal. What was once considered taboo, sometimes goes mainstream. And some things considered new have been around as long as sex itself, like birth control, abortion, and sexually transmitted infections. All that and more is contained in the new book, Been There, Done That: A Rousing History of Sex, by Rachel Feltman, executive editor of Popular Science, based in New York City. Radio producer Shoshannah Buxbaum talks with author Rachel Feltman about queer animals, crocodile dung contraception, ancient STIs, what led to the United States' original abortion ban, and more.   Processing Postpartum With AI And Synthetic Breast Milk Art One of Ani Liu's strengths as an artist is her ability to process emotion through different scientific mediums: machine learning, chemistry, 3D-printing. The result is often visceral: she's used organic chemistry to concoct perfumes that smell like people emotionally close to her and engineered a device that enables the wearer to control the direction of swimming sperm with their mind. And at her new exhibition—next to a 3D-printed sculpture of a pig's uterus—lies 328 feet of clear tubing with a milky-white substance pumped through it, a commentary on pumping breast milk as a new parent. “I wanted to use my own breast milk, but it wouldn't be stable for the duration of the show,” she said. Liu became a parent shortly before the pandemic, and she channeled that experience into a new show called “Ecologies of Care,” to process her postpartum period and the communities in her life that helped her through that time. “I hope that this can allow new parents to bond and maybe feel less lonely,” she said. “In making it, I was questioning how do we create better communities of care? I made all of this work before the formula shortage, before our reproductive rights were even more under threat. When I look at this, I'm hoping that you see this particular slice of love and labor.”   Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

Why Another Antarctic Ice Shelf Collapsed On March 15, the Conger ice shelf, a piece of ice half the size of Rome, collapsed in eastern Antarctica. It's the first time that side of the continent experienced a major loss of ice in the 40-year history of satellite observations. Previous collapses of shelves have until now occurred in western Antarctica. Meanwhile, researchers are reporting temperatures more than 70 degrees Fahrenheit warmer than average, while parts of the Arctic are beating averages by 50 degrees. Scientific American's Sophie Bushwick explains why warming at the poles is both more likely than other parts of the globe, and is also exacerbating the likelihood of collapses like this. Plus, new insights into strange radio circles in space, the Hubble telescope sees the most distant star yet, and a look at the statistical likelihood of basketball “hot hands.” And an April Fool's Day quiz on some new inventions that may or may not be real.   Scientists Are Working On HIV Vaccines Based On COVID Vaccine Tech Several early Phase 1 human trials of vaccines using mRNA technology are now under way. The approach—which uses mRNA to induce the body to manufacture specific parts of a viral structure that then trains the immune system—was famously successful in the COVID-19 pandemic, and the basis for both the Moderna and Pfizer-BioNTech vaccines. Now, researchers are wondering if the mRNA approach might be a solution to diseases like HIV, which have thwarted vaccine researchers for years. The NIH has supported three trials, other trials from IAVI and Moderna are also under way in Phase 1. Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, joins Ira to talk about the challenges of developing vaccines against HIV, the path through the clinical trials process, and why researchers are very cautiously optimistic about the new vaccine trials. They also discuss the state of the COVID-19 pandemic, and the need for continued vigilance and funding.   An Oregon Lithium Deposit Could Help Power Clean Energy Tech President Joe Biden and U.S. lawmakers are ramping up their efforts to mine, manufacture and process more battery materials at home — and that's drawn praise from the company exploring a large lithium deposit in southeast Oregon. Jindalee Resources Limited, the Australian company with lithium claims at a Bureau of Land Management site in Oregon's Malheur County, says the growing push for U.S. critical minerals production is a positive sign. “You've seen bipartisan support for the development of critical minerals projects growing,” said Lindsay Dudfield, Jindalee's executive director. “Jindalee is advancing a critical minerals project, and so we're very encouraged by these developments.” The Intercept reported Thursday that Biden is preparing to invoke the Defense Production Act to expedite production of batteries for electric vehicles, consumer electronics and renewable energy storage. The Defense Production Act was recently used to increase supply and hasten delivery of COVID-19 vaccines. Lawmakers in recent weeks have urged the president to use his authority under the law to do the same for batteries. “The time is now to grow, support, and encourage investment in the domestic production of graphite, manganese, cobalt, lithium, nickel, and other critical minerals to ensure we support our national security, and to fulfill our need for lithium-ion batteries — both for consumers and for the Department of Defense,” wrote Sens. Lisa Murkowski, R-Alaska; Joe Manchin,D-W.Va.; Jim Risch, R-Idaho; and Bill Cassidy, R-La., in a letter to the president last week. The Biden administration published a report last June that found the American battery supply chain to be extremely vulnerable as demand for batteries increases. For decades, the U.S. has relied on foreign imports of minerals needed to make those batteries, especially lithium. While the U.S. has large lithium reserves, it only produces about 1% of the world's supply. Demand for lithium and other materials is expected to skyrocket as the U.S. seeks to transition away from fossil fuels, according to the International Energy Agency. The Biden administration's report says lithium could be a good candidate for new domestic mining and extraction, which would reduce American dependence on foreign sources like Russia and China. But as the rush for critical minerals like lithium speeds up in the U.S., environmental groups, Native American tribes and others have urged caution, especially when it comes to new mining. The extractive industry remains enormously destructive to frontline communities as well as land, water and wildlife.

Over the past few decades, it has found a home in U.S. Gulf states and parts of Texas. The ant, named “crazy” for its erratic movements, can outcompete native ant species when it takes hold, and can overwhelm small animals with sheer numbers. In 2013, Science Friday spoke with Edward LeBrun, a research scientist at the Brackenridge Field Laboratory of UT Austin, about the ant and its ability to outcompete fire ants in the southern U.S. Now, LeBrun returns to share news of a possible biological control for the ants, a form of fungus that can cause infected nests to collapse over a period of years. It's a good news, bad news situation—while most insecticides and baits don't work to control the ants, the fungus can produce local extinction. However, it takes years to work, and currently requires transferring hundreds of infected ants into a nest—not exactly something you can pick up off the shelf at the local hardware store.

Space-X Booster To Hit The Moon, After Years Of Hurtling Through Space A Space-X rocket booster is on track to slam into the moon, which scientists predict will happen on March 4. The rocket was originally launched in 2015 to deploy a space weather satellite. Now, it's a piece of space junk that's been caught in limbo for the past seven years. Sophie Bushwick, technology editor at Scientific American, joins guest host Miles O'Brien to talk about that and other science stories of the week, including implications of Russian cyber warfare, climate scientist Lisa Goddard's legacy, a Lego robot with an “organic” brain, and everlasting bubbles.   A Race To Save Florida's Manatees Florida's waterways are home to a charismatic mammal: the manatee. These gentle giants are sometimes called “sea cows” for the way they graze on seagrass, the long, green plants that grow underwater in their habitat. But in Florida's Indian River Lagoon, the seagrass is disappearing fast due to algae, which is caused by pollution in the water. This loss of food has put the manatees in great peril. Last year, over 1,000 of them died—more than any year on record. While threats to manatees are not new, this accelerated die-off concerns scientists, and is prompting a search for novel ways to help the Sunshine State's sea cows. Joining guest host Miles O'Brien to talk about manatee conservation in Florida are Patrick Rose, executive director of Save the Manatees Club in Maitland, Florida, and Cynthia Stringfield, senior vice president of animal health, conservation and education at ZooTampa in Tampa, Florida.   It's A Bird. It's A Plane. It's An Astronomical Photo Bomb. Anyone who's spent any time gazing at the stars at night has had the experience of seeing an occasional satellite whizz by—a sighting that usually happens around twilight. But if you've been out in the dark lately, you may have noticed that there's a lot more traffic in space these days. With keen eyes, you might spot a series of dots moving in a straight line. That line is a “train” of satellites in low earth orbit, launched to provide broadband internet access from space. Starlink is the main company behind such efforts currently, with thousands of satellites in orbit already, but other players, such as Amazon, are joining the market as well. The companies behind them say they can provide high-speed broadband internet access to rural areas that might be out of range of a fiber optic cable or a good cellular connection. But just as you can see those lines of glowing dots, astronomers and their telescopes can see them too, making their jobs more difficult. The problem is especially acute in long-duration exposures of the night sky—in which the dots become bright streaks across an entire image. Over the past few years, astronomers and some of the companies behind the large satellite constellations have been trying to find ways to mitigate the optical interference the satellites can cause. Dr. Bruce Cameron, the director of the System Architecture Group at MIT, describes the capabilities of some of these huge satellite constellations, and who might stand to benefit from them. Dr. Connie Walker, a scientist with NSF's NOIRLab and the co-chair of four panels looking at the impact of these satellite constellations on astronomy, joins guest host Miles O'Brien to discuss the challenges these constellations could pose in the future, and her hopes for collaboration with industry to solve the problems.   Webb Telescope Arrives To Its Final Home In Deep Space After weeks of travel, the James Webb Space Telescope, or JWST, moved into its final orbit this week. Following a Christmas day launch, the spacecraft has spent a month in transit, deploying its solar array, unfolding its heat shield, and unpacking its hexagonal mirror segments. On Monday, the craft fired its engines to brake into a circular orbit around a point in space known as L2, where astronomers hope it will operate for at least 10 years. Amber Straughn, an astrophysicist at the Goddard Space Flight Center and Deputy Project Scientist for James Webb Space Telescope Science Communications, joins guest host Miles O'Brien to talk about the telescope's journey to L2. Straughn explains what will need to happen in the months ahead to fine-tune the mirrors and commission the science instruments on board before the telescope takes its first science images sometime this summer.

Travel Bans Do Little To Slow Spread Of Omicron After South African researchers first detected the new COVID variant Omicron last week, it's already been found in dozens of countries around the world, including in the United States. Travel restrictions imposed by the Biden administration and others have done little to slow its spread. Instead, experts say that increasing global vaccination rates is critical to stopping future troubling mutations from occurring and spreading. In other news, scientists are re-testing a foundational piece of science, the Miller-Urey experiment, first conducted in 1952, which simulated how life on earth could have originated. Scientists are questioning their old assumptions that the glass container in the original experiment was inert. Joining Ira to talk through these and other big science stories of the week is Sophie Bushwick, Technology editor at Scientific American.   Ralph Nader Reflects On His Auto Safety Campaign, 55 Years Later It's hard to imagine a world without seatbelts or airbags. But five decades ago, it was the norm for car manufacturers to put glamour over safety. “It was stylistic pornography over engineering integrity,” Ralph Nader, prolific consumer advocate and several-time presidential candidate, tells Science Friday. This winter marks the 55th anniversary of Nader's groundbreaking investigation, “Unsafe at Any Speed,” a damning look at how little auto safety technology was in vehicles back in the 1960s. The book had a massive effect on auto safety in the U.S., setting the groundwork for laws about seatbelts, and the creation of the United States Department of Transportation. Nader joins Ira to discuss what's happened over 55 years of auto safety advances, and what kind of work is needed to make sure new technology, like self-driving cars, have the safety checks they need before going out on the roads.   New Drug Reverses Paralysis In Mice With Spinal Cord Injuries Nearly 300,000 people are living with spinal cord injuries in the United States. Currently, recovery or effective treatment remains elusive. Researchers haven't yet figured out a reliable way to knit back together severed spinal cords or nerves. Now, a new study in mice shows promising potential to prevent paralysis after injury. Researchers gave paralyzed mice a specially formulated injection that uses a novel technique called “dancing molecules.” And after a month, the mice were walking again. Joining Ira to better understand this new development in spinal cord treatment is Samuel Stupp, professor of materials science, chemistry, biomedical engineering and medicine, and director of the Simpson Querrey Institute for BioNanotechnology at Northwestern University in Chicago, Illinois.

The Science Behind Cryptid Sightings People around the world have long been fascinated by the idea that there are strange creatures out there, ones that may or may not exist. Tales circulate about cryptids–animals whose existence can't be proved—like Bigfoot hiding out in American forests, or sea serpents lurking just below the water in coastal towns. Despite the best efforts of monster hunting T.V. shows and amateur sleuths, there may never be concrete proof that these creatures exist. But that doesn't stop people from analyzing strange photographs or odd carcasses and saying maybe, just maybe, cryptids do exist. Darren Naish, a paleontologist and author based in Southampton, U.K., has a particular interest in looking at cryptozoology—from a skeptical perspective. His breakdowns of cryptid sightings from a scientific perspective have been published in Scientific American, his website, and in his book, Hunting Monsters: Cryptozoology and the Reality Behind the Myths. Darren speaks to guest host Sophie Bushwick about faked evidence, his relationship with cryptozoology, and how cryptids may lead to other pseudoscience beliefs.   Stories From Those On The Frontlines Of Sea Level Rise Next week marks the start of the UN's annual conference on climate change in Glasgow, Scotland. It's a big moment for global consensus on climate change: Nations are supposed to make new, aggressive pledges to lower their emissions in the attempt to prevent the planet from hitting 1.5 degrees Celsius of warming. Meanwhile, in the world we see and touch, seas are already rising. In some coastal areas, seas have risen between 0.5 to 1.5 feet in the last century. We're also already seeing hurricanes with higher storm surge, and heavier rainfall. More change, of course, is projected. The SciFri Book Club has been talking about these risks, and reading about how these numbers have endangered wetlands, flooded homes, lost livelihoods, and sometimes scattered communities in Elizabeth Rush's 2018 book Rising: Dispatches From The New American Shore. But while we've talked to wetland scientists and Elizabeth herself, the voices of community members most affected by climate change—a key part of Rising's mission—were still missing. In a final conversation with guest host Sophie Bushwick, producer Christie Taylor shares some of the stories of people on the frontlines, including a real-estate agent who helped his neighbors relocate after Hurricane Sandy, and the leader of the Gullah Geechee people on the sea islands of the southeast coast. Plus, social scientist A.R. Siders' insights into communities' need to adapt to sea level rise, and how they can be most successful.   Listen To The Haunting Howls That Once Permeated Europe Last year, Melissa Pons, a field recordist and sound designer, set out to capture a sound that at one time would have been familiar to almost any European: the howl of an Iberian wolf. There was a time when the sounds of wolves filled the forests and mountains of Europe. But after centuries of persecution by humans, only some 12,000 wolves remain in all of Europe. Isolated pockets of wolves can be found in Italy, Spain, Greece, and Finland. A sixth of the entire remaining population lives in the mountains of Portugal. Pons headed to the remote, mountainous region of Picão—a settlement on the small island Príncipe off the west coast of Africa—where there is a rehabilitation center for the Iberian wolf. There are some 350 packs of wolves spread out over about 45 acres of the reserve. Pons first explored the region and observed the wolves. Then she set up her recording gear and gathered over 100 hours of tape. From those recordings, she composed an album where each track captures a distinct soundscape made by these wolves. The album is available online and half the proceeds go toward supporting the rehabilitation center in Portugal.

Younger Kids Next In Line For COVID-19 Vaccines This week, an FDA advisory panel voted unanimously to recommend that the COVID-19 vaccine made by Pfizer vaccine be approved for children as young as 5. If the FDA concurs and the CDC agrees, lower-dose Pfizer vaccinations could soon be available for children ages 5 to 11, via local pediatricians. Just who will be immediately eligible for the doses, and how vaccinating young children might affect school mask policies and other restrictions, remains to be seen. Umair Irfan, staff writer at Vox, joins Sophie Bushwick to talk about the news and other stories from the week in science, including potential COVID-related criminal charges against Brazil's Jair Bolsonaro, an experimental bionic vision implant, and the possible discovery of an exoplanet in the galaxy Messier 51.   Could Ordinary Household Objects Be Used To Spy On You? In the movies, if a room is bugged, the microphone might be hidden in a potted plant. But in recent years, researchers have come up with ways to use the trembling leaves of a potted plant, light glancing off a potato chip bag, and even tiny jiggles in the head of a spinning hard drive caused by a nearby conversation to be able to listen to what's happening in a room, or to gain information about what's going on nearby. On a larger scale, other researchers have been able to use the vibrations of an entire building to paint a picture of movements within it—and even the health status of the people inside. The approach is known as a side-channel attack: Rather than observing something directly, you're extracting information from something else that has a relationship with the target. Many of the approaches are not straightforward—they require an understanding of the physics involved, and sometimes heavy data-processing or machine learning to interpret the hazy information yielded by these techniques. Jon Callas of the Electronic Frontier Foundation, Hae Young Noh of Stanford, and Kevin Fu of the University of Michigan join host Sophie Bushwick to talk about the risks and opportunities afforded by these sneaky methods of surveillance, and how concerned you should be.   A Maggot Revolution In Modern Medicine In a bloody battle during World War I, two wounded soldiers were stranded on the battlefield in France, hidden and overlooked under some brush. Suffering femur fractures and flesh wounds around their scrotum and abdomen, they lay abandoned without water, food, or shelter for a whole week. At the time, outcomes for these kinds of wounds were poor: Patients with compound femur fractures had a 75 to 80% mortality rate. By the time the soldiers were rescued and brought to a hospital base, orthopedic surgeon William Baer expected their wounds to be festering, and their conditions fatal. But much to his surprise, neither showed any signs of fever, septicaemia, or blood poisoning. When his team removed the soldiers' clothing, they discovered that their flesh wounds were filled with thousands of maggots, or baby flies—little larvae with a massive appetite for decaying matter. Baer was repulsed by the sight, and the team quickly washed off the wriggling maggots. Underneath, instead of the expected pus and bacteria-infected flesh, Baer marveled over “the most remarkable picture.” “These wounds were filled with the most beautiful pink granulation tissue that one could imagine,” Baer later wrote in a 1931 report in the Journal of Bone and Joint Surgery. Maggots have long been associated with death, but in this case, they were helping the soldiers stay alive. As these insects were simply tucking in for their typical meal of dead, decaying flesh, they were inadvertently aiding the soldiers by cleaning their wounds, keeping infection at bay. The soldiers recovered—saved by their tiny, wriggling “friends which had been doing such noble work,” Baer wrote. Baer's paper is one of the first reports of maggots used in medicine, but these insects have been found healing wounds for thousands of years, with references in the Old Testament and in ancient cultures of New South Wales and Northern Myanmar.

Sophie Bushwick, technology editor at Scientific American, joins Ira to talk about the mission and other stories from the week in technology and science—including tiny airborne micro-machines, an upcoming voyage for the James Webb Space Telescope, and the discovery of ancient kids' handprints that could be the world's oldest-known art.   Congress Is Considering Two Climate Change Bills. What's In Them? President Biden has made many promises about slowing climate change. During his campaign, he pledged to bring the United States' energy sector to zero carbon emissions by 2035. On Earth Day this year, he pledged to reduce total U.S. greenhouse gas emissions by 50% by 2030, and by 100% by 2050. But the key policy changes that will help the country get there remain pending as the relevant bills continue to make their way through Congress. The first is an infrastructure bill that would pledge billions toward cleaner transit and resiliency projects in disaster-stricken communities. But that measure is tied intricately with the fate of a second, $3.5 trillion budget bill that would direct billions of dollars to incentivize coal and natural gas-burning utilities to switch over to renewable energy. If both are to pass without substantial changes, they rely on consensus among the narrow majorities of Democrats in the Senate and the House—neither of which is guaranteed. New York Times reporter Coral Davenport walks through what's in the bills, and why so much is still up in the air even after a summer of climate-driven disasters.   Behind The Booster Battle Update 9/24/2021: This week, CDC director Rochelle Walensky overruled the recommendations of an advisory panel and authorized a third dose of the Pfizer COVID-19 vaccine for the elderly and certain “high risk” individuals, mirroring an earlier FDA decision. In late August, President Biden had said that COVID-19 vaccine booster shots might soon be on the horizon for many Americans. In late August, President Biden said that COVID-19 vaccine booster shots might soon be on the horizon for many Americans.

With Delta Rising, New Rules On Masks And Vaccines This week, the CDC released new guidelines for mask use in the U.S., just months after many cities and towns relaxed mask mandates. The guidance says that “to reduce their risk of becoming infected with the Delta variant and potentially spreading it to others: CDC recommends that fully vaccinated people wear a mask in public indoor settings if they are in an area of substantial or high transmission.” Right now, many parts of the country fall under that category. In response to the guidance, several municipalities re-instituted mask mandates for their communities. This week, New York chose to require either COVID-19 vaccination or weekly testing for public employees. Other municipalities have also announced vaccine requirements—and some private companies, including Facebook, have also indicated that vaccination will be required for employment.

Is The Truth About UFOs Out There? Over the past several years, U.S. Navy pilots have reported several instances of ”unexplained aerial phenomena” while in flight. They've recorded videos that show shapes that appear to move in unusual ways, zooming and turning in ways  beyond the capabilities of our own aircraft. After several members of Congress requested an explanation for the videos, the government put together a report on the phenomena.   The report, however, doesn't definitively answer the question of what the observations show. While it does say that the observations aren't of secret U.S. technology, it has no conclusions on whether the reports show foreign technology, camera artifacts, or something else—like alien technology. Seth Shostak, senior astronomer at the SETI Institute, spends his time searching for signs of intelligent life elsewhere in the universe. He says that while he does believe intelligent alien life exists—and may even be discovered within the next 20 years or so—he does not think the sightings included in the government report indicate alien visitors. He shares his reasons for skepticism with host Sophie Bushwick, as well as talks about people's desire to believe in extraterrestrials.  Rats Learn To Hide And Seek  One of the most wonderful things about the internet is how you could spend years watching videos of animals at play. There's the classic cat-playing-with-a-box genre. You can also watch a dog playing jenga. And you can type in pretty much any combination of animals, along with the word “playing,” and find adorable videos—like a baby deer, rough-housing with a lemur. Incredible stuff.  Neuroscientist Juan Ignacio Sanguinetti of the Humboldt University of Berlin gets inspiration for his work by watching home videos like that. And in his latest work, in the journal Science, he describes playing hide-and-seek—with rats. Making Music To Sharpen Aging Brains While research continues on drugs that can slow or reverse the- damage of Alzheimer's disease, there is already evidence for a lower-tech intervention: music. Research on the benefits of listening to music has found some evidence that it can activate regions of the brain not damaged by disease progression, soothe emotional disturbances, and promote some cognitive improvement in later stages of Alzheimer's. A new analysis in the Journal of the American Geriatric Society earlier this year looked at a different question. Can making music, whether by playing a musical instrument or singing, have an effect on the brains of people in the early stages of cognitive decline? The team focused specifically on people experiencing ‘mild cognitive decline,' which can be the first step in a progression toward Alzheimer's disease or more serious dementia. The researchers found evidence from 21 studies, involving more than 1,400 participants around the world, that yes, playing musical instruments, singing, or otherwise participating in making music can have a small but consistent benefit in recall, and other measures of brain health. Lead author Jennie Dorris, a professional percussionist turned PhD student studying rehabilitation sciences, talks to guest host Sophie Bushwick about the evidence for cognitive improvement, and what questions still remain about the effects of active music participation on the brain.

California's Climate Program Is Actually Adding Carbon To The Atmosphere California has a reputation as the state that's doing the most about climate change. And the lynchpin of those efforts is California's Cap-and-Trade program, where the state's biggest polluters—like ExxonMobil, BP, and others—are required to offset their carbon dioxide emissions by investing in carbon reduction strategies. But according to a recent investigation by ProPublica and others, this climate solution is actually adding millions of tons of carbon to the atmosphere. They discovered a loophole in the state's forest offset program, which seeks to reduce carbon emissions by preserving trees. Uncovered by additional reporting, they found that the Massachusetts Audubon Society, a forest conservation organization, enrolled 9,700 acres it owned into California's program and received the credits, even though it was unlikely that Mass Audubon ever intended to cut down its preserved forests. The intended use of these offsets was to change the behavior of landowners who were likely to cut down trees, releasing carbon dioxide in the atmosphere. The result, in this instance, seemed to go against the spirit of the Cap-And-Trade program, that the state's biggest polluters' emissions weren't truly being offset. Guest host Sophie Bushwick is joined by Lisa Song, a ProPublica reporter who broke this story with MIT Technology Review, with help from Carbon Plan, a nonprofit that analyzes the scientific integrity of carbon removal efforts.

What Went Wrong With Jackson, Mississippi’s Water? Residents of Jackson, Mississippi have been dealing with a water crisis since a storm rolled through town on February 15th. The city’s water system was damaged, leaving thousands of residents without running water at home. People have relied on water distribution sites to get by, and even those who can still use their taps are on boil water notice. Impacted residents are largely low-income, and the limited access to water has raised worries about staying safe during the COVID-19 pandemic. Even before this fiasco, Jackson’s water system was in need of a change. Boil water advisories were common, and many of the city’s pipes date back to the 1950s. Water service is expected to be restored this week, but getting the taps running again will just be a Band-Aid: A true overhaul would require millions, if not billions of dollars. Mississippi Public Broadcasting reporter Kobee Vance joins guest host John Dankosky to discuss what’s happening in Jackson, and why its infrastructure was particularly vulnerable to this crisis.   Spinning Glass To See The Stars Last weekend, a giant furnace built under the east stands of the University of Arizona football stadium began to spin. That furnace contained some 20 tons of high-purity borosilicate glass, heated to 1,165 degrees C. As the glass melted, it flowed into gaps in a mold. The centrifugal force of the spinning furnace spread the material up the edges of the mold, forming the curved surface of a huge mirror, with a diameter of 8.4 meters. The piece is just one of seven sections that will eventually form the 25-meter primary mirror of the Giant Magellan Telescope in Chile. It’s not a fast process—it will take several months to cool, and then another two years to measure, grind, and polish. When that’s complete, the surface of the mirror segment will be accurate to within twenty-five nanometers. Steward Observatory mirror polishing program project scientist Buddy Martin says that when it’s complete, the Giant Magellan Telescope should be ten times sharper than the Hubble Space Telescope—if it was positioned in Washington, DC, it would be able to make out a softball in the hand of a pitcher in San Francisco. Martin talks with SciFri’s Charles Bergquist about the mirror production process, and the challenges of working with glass on massive scales. Watch a video and see photos of the process at scienefriday.com.   It’s Time To Rethink Shark Sex—With Females In Mind Sharks, rays, and skates—all fish in the subclass Elasmobranchii—are a beautifully diverse collection of animals. One big way they differ is in how they reproduce. They lay eggs, like traditional fish, and let them mature in a select corner of the ocean. Or, they might let the eggs hatch inside their bodies. But they can also give live birth to pups gestated like mammals: with an umbilical cord and a placenta in a uterus. It doesn’t end there. These fish, like many other members of the animal kingdom, have two uteruses. Females are capable of reproducing asexually, without help from a male. As genetic sequencing has advanced, researchers have been finding another curious pattern: Many litters of pups will have more than one father, a phenomenon known as multiple paternity. Evolutionary ecologists seeking to explain why sharks would use this strategy of multiple paternity have hypothesized it’s one of convenience for females. In species with aggressive and competitive mating practices, like many sharks and rays, it’s possible females find it saves them precious resources to acquiesce to multiple males. But what if there’s something in it for the female, and her likelihood of having successful, biologically fit offspring? That’s the question a team of researchers sought to answer in new research published in Molecular Ecology this month, where they asked what kinds of physiological mechanisms a female shark or ray might use to wield agency in her own reproduction. The researchers also write that a male-dominated field may be more likely to miss a female-driven reproductive strategy, and push for more study of female reproductive biology. John Dankosky talks to the lead author on the research, Georgia Aquarium shark biologist Kady Lyons, about the vast wonderland of reproductive strategies in this fish subclass—and what a history of male-centered research may have missed.   What Next For The Fully Vaccinated?

She received a first dose of the vaccine made by Pfizer and BioNTech, and will require a second dose in several weeks to achieve the full effect. Nations around the world are racing to implement vaccination programs. The clinical use of the vaccine in the U.K. came just six days after the vaccine obtained emergency approval.

Charting A Path To Deliver The COVID-19 Vaccine Last week, the United Kingdom approved a COVID-19 vaccine developed by Pfizer through an emergency authorization, and vaccinations began this week.

COVID-19 Vaccinations Begin In The U.K. This week, the U.K. began its vaccination effort against COVID-19 with Margaret Keenan, a 90-year-old woman from Coventry, becoming the first U.K. resident to receive the shot. She received a first dose of the vaccine made by Pfizer and BioNTech, and will require a second dose in several weeks to achieve the full effect. Nations around the world are racing to implement vaccination programs. The clinical use of the vaccine in the U.K. came just six days after the vaccine obtained emergency approval. This week, Canada also gave emergency approval to the Pfizer approach, and could start vaccinations next week. And the FDA is meeting this week to examine trial data and could soon approve treatments here. Sophie Bushwick of Scientific American joins guest host John Dankosky to talk about the vaccination effort and other stories from the week in science, including the return to Earth of asteroid material sampled by the Hayabusa2 mission, the finding that human-made stuff now outweighs all living things on Earth, and an advance in bionic eye development. What Has Europe’s Green New Deal Accomplished In Its First Year?  Just over a year ago, the Youth Climate Movement was at its peak. Millions of people were protesting government inaction in the face of rising global temperatures.  Nearly everything about the world has changed since then. And while the incoming Biden Administration has said it will adopt parts of the “Green New Deal,” the U.S. has failed to capitalize on the momentum of last year’s Global Climate Strikes. In Europe, however, the European Commission unveiled the “European Green New Deal in December of 2019. This 24-page document lays out a plan to make Europe climate neutral by 2050. Despite the pandemic, the commission has since made progress on many of its climate goals.

Biden Climate Plan, Boiling River. August 7, 2020, Part 1

Last month, Vice President Joe Biden unveiled his plan for climate change—a sweeping $2 trillion dollar platform that aims to tighten standards for clean energy, decarbonize the electrical grid by 2035, and reach carbon neutrality for the whole country by 2050. Biden’s plan, like the Green New Deal, purports to create millions of jobs at a time when people are reeling financially from the pandemic—proposing employment opportunities including retrofitting buildings, converting electrical grids and vehicles, and otherwise transforming the country into an energy efficient, emissions-free economy. But are the foundations of this plan on solid scientific ground? Yes, say Ira’s guests, political scientist Leah Stokes and energy systems engineer Sally Benson. Stokes and Benson run through Biden’s proposals, explaining what’s ambitious, what’s pragmatic, and what people might show up to vote for. Deep in the largest rainforest of Latin America is the Peruvian Boiling River, a name earned from water that can reach 100°C—or about 212°F.  While the river is hot enough to cook any animal unfortunate enough to wind up in it, its microbes don’t mind. They can handle the heat—and their odd survival mechanisms might have medicinal value.  Joining Ira to talk about these tiny heat-seekers and the Peruvian Boiling River is Rosa Vásquez Espinoza, a Ph.D. candidate in chemical biology at the University of Michigan.  See photos and video of Rosa Vásquez Espinoza’s expedition to the Boiling River and learn more about her research on extreme microbes in a feature article on SciFri.  It’s been a busy week for science news. Cities are still grappling with COVID-19, and in New York City, previously the country’s largest coronavirus hotspot, health commissioner Oxiris Barbot has resigned. She cited Mayor Bill de Blasio’s handling of the pandemic as her reason for doing so, issuing a scathing statement on her way out the door. Barbot is just one of the many health officials around the country who have butted heads with the politicians that oversee them during the pandemic. And across the world, devastating explosions in Beirut, Lebanon have injured thousands and killed several dozen. As officials piece together why this happened, they’re pointing to a warehouse of ammonium nitrate as the source of the blasts.  Joining Ira to talk about these stories, and other science news of the week, is Sophie Bushwick, technology editor at Scientific American in New York, New York.

It’s the start to a holiday weekend, which often means spending time outdoors, whether that’s going to the beach, on a hike, or grilling in a park. But not everyone feels safe enjoying the great outdoors—and we’re not talking about getting mosquito bites or sunburns. In late May, a white woman, Amy Cooper, called the police on a Black bird watcher who asked her to leash her dog. This incident felt familiar to many other Black outdoor enthusiasts, many of whom had encountered similar experiences of racism outside. To understand why the outdoors is an unwelcoming place for some people, we need to look back at our violent history. Joining Ira to talk about this is Dr. Carolyn Finney, author of the book Black Faces, White Spaces. She is also a scholar-in-residence at Middlebury College in Vermont. And later in the conversation, Ira is joined by two scientists, biology graduate student Corina Newsome from Statesboro, Georgia, and exploration geoscientist Tim Shin from Houston, Texas. They’ll talk about what it’s like to do fieldwork while Black, and what responsibility academic institutions should have in keeping their students safe.   As coronavirus cases surge across the U.S., including in Texas, Florida, Arizona, and California, it’s more important than ever to have an accurate and real-time understanding of transmission. Epidemiologists have been measuring the spread of the virus based on the number of individual people who test positive. But depending on when people get tested, and how long it takes to get their results, confirmed cases can lag days behind actual infections. Luckily, there’s another way to find out where people are getting sick: The virus that causes COVID-19 can be detected in feces, and for months, researchers have been studying whether sampling sewage systems can help identify new outbreaks faster. Scientific American technology editor Sophie Bushwick joins Ira to talk about the value of sewage tracing for COVID-19. Plus, a new sparrow song has gone viral in Canada, and why summer fireworks can damage not only your hearing, but also your lungs.

To give us the fairy tale perspective, our guest is Tabled Fables Podcast co-host Sophie Bushwick, who adds context on the varied history and mixed morals of Sleeping Beauty as told by Brothers Grimm and Charles Perrault.While we appreciate that Maleficent subverts some stale tropes like "true love's kiss" and actually puts its female characters in center of the action, we find some of the more adult themes of this PG film quite troubling. Plus: Why do we need villain origin stories in the first place?
