Hurricane Helene's Effect On The Global Tech Industry | A Stretchy Band-Aid For The Heart
4 oktober 2024 · 25 min
The storm flooded mines in Spruce Pine, North Carolina, which supply the tech industry with some of the purest quartz in the world. Also, researchers developed a 3D-printable material, inspired by worms, that can act as a Band-Aid for damaged heart and cartilage tissue. Lees meer
Hurricane Helene’s Damage Could Affect The Global Tech Industry
After making landfall on September 26, Hurricane Helene devastated regions in the southeastern US. Over 200 people are confirmed dead so far. About a million people are still without power, and many lack clean water.
As climate change intensifies, hurricanes like Helene are expected to occur more often and be more intense. What’s become very clear in the last few years is that due to the interconnectedness of the modern world, extreme weather in one place can have global implications.
For example, Spruce Pine, North Carolina, home to around 2,200 people, flooded during Hurricane Helene. The town is also home to several mines that produce some of the world’s purest quartz, an ingredient necessary to make solar panels, smartphones, semiconductors, and more.
Ira talks with Umair Irfan, senior correspondent at Vox, about this and other science news of the week, including a completed map of a fruit fly’s brain, how scientists in the United Kingdom are screening newborns for rare diseases, and how octopuses and fish are hunting as a team.
A Strong, Stretchy, And Sticky Band-Aid For The Heart
The heart is an impressive organ that has to beat constantly for years. But what happens when heart tissue is damaged? Or when cartilage in joints like our knees wears out? These constantly moving tissues don’t regenerate easily, and there aren’t a lot of great treatment options.
To address these kinds of problems, a team at University of Colorado Boulder invented a new strong, stretchy, and sticky hydrogel material that could act as a Band-Aid to heart or tissue lesions. They were inspired by masses of worms that tangle and untangle themselves, b…

Herbicides Approved For Public Land | Hidden Physics In Van Gogh’s ‘The Starry Night’
3 oktober 2024 · 18 min
This summer, the Bureau of Land Management approved seven herbicides to fight invasive plants in the West. Also, when scientists analyzed the swirls in the famous painting, they found Van Gogh depicted forces of nature with startling accuracy. Lees meer
What Newly Approved Herbicides Could Mean For Federal Land
Invasive plants are a big problem across the western US.
Cunning interlopers like cheatgrass, leafy spurge and red brome can outcompete native vegetation, crowd habitats and steal water and other vital soil nutrients.
Of the 245 million acres controlled by the Bureau of Land Management, harmful non-native plants have already infested 79 million acres—an area larger than the states of Pennsylvania, Virginia and South Carolina combined. That’s why the federal agency felt the urgency to approve seven new herbicides to kill invasives on its land nationwide, said Seth Flanigan, a BLM senior invasive species specialist based in Idaho.
“If we don’t remove this now, what is it going to look like 10 years from now?” he said.

The Hidden Physics In Van Gogh’s ‘The Starry Night’
One of Vincent Van Gogh’s most famous creations is “The Starry Night,” an oil painting of a quaint French village at night with a blue night sky that dramatically swirls around the yellow stars and moon.
It’s easy to admire this painting as a casual viewer, but if you research fluid dynamics, one thing in particular stands out: those iconic swirls in the sky. To a physicist, they look an awful lot like the swirls that atmospheric turbulence produces. And some researchers have been wondering if Van Gogh’s swirls actually match the mathematical models of turbulence theory.
Well, a team of researchers from China and France set out to analyze all the swirls in “The Starry Night,” and it turns out that Van Gogh had a knack for depicting the forces of nature. Their results were published in the journal Physics Of Fluid.

Greenhouse Gases From Anesthesia | Fighting Militarization In The Mariana Islands
1 oktober 2024 · 18 min
Emissions from anesthesia are one of the largest sources of greenhouse gases from hospitals. This anesthesiologist wants to change that. And, a cultural anthropologist discusses the Mariana Islands’ long history of colonization and why demilitarization matters for climate progress. Lees meer
A Major Source Of Greenhouse Gases In Hospitals? Anesthesia
Did you know that some of the gases used in anesthesia are strong greenhouse gases? A few years ago, Seattle Children’s Hospital analyzed its carbon footprint and found that the gases used in anesthesia made up about 7% of the hospital’s total emissions, right behind emissions from heating and power and those from commuting.
Faced with this problem, Dr. Elizabeth Hansen, a pediatric anesthesiologist at Seattle Children’s, took matters into her own hands and slashed the operating room’s emissions. She now helps other hospitals do the same with Project Spruce.
Guest host Anna Rothschild talks with Dr. Hansen about how and why she took on the problem.
Militarization And Environmental Injustice In The Mariana Islands
Let’s take a trip to the Northern Mariana Islands, a string of islands in the Pacific just north of Guam. The islands were sites of major battles during World War II and were captured by the United States in 1944. The US established a military presence across the territory—including building the world’s largest air force base at the time, on an island called Tinian.
The US military never left, and in the 1980s, the Northern Mariana Islands became a US territory. A few years ago, the Pentagon proposed building a bombing range on an island called Pagan, but residents of the islands pushed back.
Dr. Isa Arriola is a cultural anthropologist at Concordia University in Montreal and co-founder of the organization Our Common Wealth 670, based in Saipan, the capital of the Northern Mariana Islands. She’s fought back against the militarization of her home islands, and she talks with guest host Anna Rothschild about how th…

Empowering Older Adults To Step Up For The Climate
30 september 2024 · 17 min
If you’re a baby boomer, you may remember the first Earth Day, the Civil Rights Movement, anti-war protests, and the first Pride parade. The list goes on, because the 1960s and 70s were packed with social revolutions. But the organization Third Act has a message for boomers: Your work isn’t done yet. Lees meer
Third Act empowers folks over the age of 60 to get involved in the climate movement. It aims to leverage older generations’ access to power, money, and life experiences to create change.
Ira Flatow talks with Third Act founder Bill McKibben and lead advisor Akaya Windwood about the importance of including older adults in the climate movement.

Microsoft Makes Deal To Restart Three Mile Island | Fish That Use Their Legs To Taste
27 september 2024 · 25 min
The company is betting big on nuclear energy to meet increasing power needs of data centers and new technologies like AI. Also, new research into a strange fish known as the sea robin finds that leg-like appendages can “taste” prey buried in the sand. Lees meer
Microsoft Makes Deal To Restart Three Mile Island
Three Mile Island in Pennsylvania has quite a reputation in the world of nuclear energy: One of its reactors suffered a catastrophic partial meltdown in 1979, earning the title of the largest nuclear accident in US history. The failed reactor has been inoperable since the accident, while the other reactor shuttered in 2019.
But now, tech giant Microsoft has made a deal with the nuclear site to reopen Three Mile Island, and purchase all of its generating capacity over the next 20 years. As Big Tech bets big on artificial intelligence, the need for electricity to power data centers is increasing tremendously. Former Microsoft CEO Bill Gates is a large investor in nuclear energy.
To help Science Friday celebrate Climate Week NYC, Casey Crownhart, climate reporter for MIT Technology Review joins guest host Anna Rothschild to discuss this and other top climate stories of the week.
These Fish Use Their Legs (Yes, Legs) To Taste
Your legs may help you get around, but what if they could also help you sniff out a snack? That’s a trick achieved by a fish called the sea robin. The fish, which lives on the seafloor, has an unusual appearance, with wing-like fins and leg-like appendages that it uses to walk along the ocean bottom. But in work published this week in the journal Current Biology, researchers report that those legs are also chemical sensing organs that can taste for prey buried under the sand.
Dr. Nicholas Bellono, a professor of molecular and cellular biology at Harvard, first learned of the unusual fish on a visit to the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, where he was planning to obtain squid and octopus for another research proje…

Former NIH Director Reflects On Public Mistrust In Science
26 september 2024 · 24 min
In 2021, Dr. Francis Collins stepped down after a dozen years leading the National Institutes of Health. He had just overseen the government’s response to the COVID-19 pandemic,in the early days of changing public health guidance as scientists learned more about this new virus. He was also involved in the quickest development of a vaccine in history. Lees meer
Now, he’s had some time to reflect on how the US arrived at such a divisive place about COVID-19 and vaccines, how trust in science has dwindled, and what we can do about it.
Ira sits down with Dr. Collins to talk about the lessons from his new book, The Road to Wisdom: On Truth, Science, Faith and Trust, and why he decided to speak publicly about his prostate cancer diagnosis.

How Are AI Chatbots Changing Scientific Publishing?
25 september 2024 · 18 min
Since ChatGPT was released to the public almost three years ago, generative AI chatbots have had many impacts on our society: They played a large role in the recent Hollywood strikes, energy usage is spiking because of them, and they’re having a chilling effect on various writing-related industries. Lees meer
But they’re also affecting the world of research papers and scientific publishing. They do offer some benefits, like making technical research papers easier to read, which could make research more accessible to the public and also greatly aid non-English speaking researchers.
But AI chatbots also raise a host of new issues. Researchers estimate that a significant amount of papers from the last couple years were at least partially written by AI, and others suspect that they are supercharging the production of fake research papers, which has led to thousands of paper retractions across major journals in recent years. Major scientific journals are struggling with how to set guidelines for generative AI use in research papers, given that so-called AI-writing detectors are not as accurate as they were once thought to be.
So what does the future of scientific publishing look like in a world where AI chatbots are a reality? And how does that affect the level of trust that the public has with science?
Ira Flatow sits down with Dr. Jessamy Bagenal, senior executive editor at The Lancet and adjunct professor at University of North Carolina at Chapel Hill, to talk about how generative AI is changing the way scientific papers are written, how it’s fueling the fake-paper industry, and how she thinks publishers should adjust their submission guidelines in response.

Earth May Once Have Had A Ring Like Saturn | An AI For Sand
20 september 2024 · 22 min
The ring would have gradually fallen to Earth as meteorites, correlating to a spike of impacts seen in the geological record. Also, a new AI tool can judge whether sand came from a beach, a river, a glacial deposit, or a wind-blown dune. Lees meer
Earth May Once Have Had A Ring Like Saturn
Hundreds of millions of years ago, Earth may have looked quite different when viewed from space: Scientists propose it may have had a Saturn-like ring, made up of lots of smaller asteroids.
The new paper, published in Earth and Planetary Science Letters, proposes that this ring formed around 466 million years ago. A major source of evidence is a band of impact craters near the equator. The researchers also posit the ring would have shaded this equatorial area, possibly changing global temperatures and creating an icehouse period.
Ira speaks to Rachel Feltman, host of the Popular Science podcast “The Weirdest Thing I Learned This Week,” about this and other top science stories of the week, including how lizards use bubbles to “scuba dive” underwater, and ancient cave art that possibly shows a long-extinct species.
An AI To Identify The Environment A Grain Of Sand Came From
If you were given a bucket of sand and asked to determine where it came from, you’d probably have a hard time guessing if it was from a beach, a riverbank, the playground down the street, or a Saharan sand dune.
There are experts who can make a guess at that sort of ID, using a categorization process that takes skill, a scanning electron microscope, and hours of time. Now, however, researchers report in the Proceedings of the National Academy of Sciences that they’ve developed an AI model that can quickly judge whether a sample of sand came from a beach, a river, a glacial deposit, or a wind-blown dune.
That type of identification isn’t just of interest to geologists. Sand is one of the world’s most in-demand resources, second only to water in use. And different applications need different types of sand—for instan…

Physicists Create Heaviest Antimatter Nucleus | Bird Species May Team Up For Migration
19 september 2024 · 19 min
The heaviest antimatter nucleus to date was spotted in a particle accelerator. It could provide new insights into the nature of matter. And, research indicates different songbird species might intentionally travel together during migration, giving each other a possible boost in survival. Lees meer
Physicists Create Heaviest Antimatter Nucleus Yet
Antimatter is one of science’s great mysteries. It is produced all around us for fractions of a second, until it collides with matter, and the particles annihilate one another. But what is it?
Antimatter is just like matter, except for one thing. Its particles have the same mass as ordinary matter, but an opposite charge. For example, an electron has a negative charge, so an anti-electron—called a positron—weighs the same, but has a positive charge.
Antimatter is a natural product of some types of radioactive decay and cosmic ray collisions, but it can also be made in particle colliders here on Earth. But making antimatter particles this way is difficult and expensive—let alone controlling them enough to create an entire anti-atom. NASA estimates that creating a gram of antimatter would cost about $62.5 trillion.
But why does antimatter matter? It may hold the key to understanding one of the universe’s biggest mysteries: why there’s something rather than nothing. Cosmologists say that during the Big Bang, matter and antimatter should have been created in equal amounts. But everything around us today is mostly matter, meaning either that there was an excess of matter created, or that matter and antimatter don’t quite follow the rules physicists expect.
Recently, scientists at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider spotted 16 instances of the heaviest exotic antimatter nucleus observed to date: antihyperhydrogen-4.
To explore what this breakthrough means for antimatter research, SciFri producer Charles Bergquist talks to Dr. Jamie Dunlop, associate department chair for nuclear physics at Brookhaven Nat…

Your Questions About The Updated COVID Vaccines, Answered
18 september 2024 · 18 min
SciFri producer Kathleen Davis talks with Dr. Kizzmekia Corbett-Helaire, assistant professor of immunology and infectious diseases at Harvard’s T.H. Chan School of Public Health to help answer our listeners’ top questions about the updated COVID-19 vaccines. Lees meer
This Q&A, which includes questions from our audience members, has been adapted from our interview with Dr. Kizzmekia Corbett-Helaire. It has been edited for clarity and brevity.
If I’ve already had COVID and it wasn’t so bad, why should I even bother with this new booster?
There’s always a chance that COVID-19 will cause more than the sniffles, or that you could end up in the emergency room—especially for older people. Why take that chance when you have the option to go to your local CVS and, in many cases, get a free vaccine that has been proven to decrease your chances of more severe disease?
My hope is that as time progresses, people become more comfortable with the idea of getting seasonal vaccinations for COVID-19 along with flu.
Is the new COVID-19 vaccine one shot?
Yes.

To Confront Climate Change, Imagine Getting It Right
17 september 2024 · 18 min
Part of the reason it’s difficult to talk about climate change is that it can be hard to see a long-term positive outcome for people and the planet. But Dr. Ayana Elizabeth Johnson, a marine biologist and co-founder of the Urban Ocean Lab, argues that to prevent the worst effects of climate change, we have to start by asking ourselves, what if we get it right?

She’s the author of a new book with that same title, What If We Get It Right? Visions of Climate Futures. In the book, she poses that question to experts in oceans, farming, architecture, finance, and even Hollywood to find out what getting it right looks like in their own fields and what those solutions could look like for the rest of us.

What Research Shows About Smartphone Bans In Schools
16 september 2024 · 18 min
Kids and teens are back in school, and the battle over the smartphones in their pockets is becoming more prominent. For years, teachers and parents have lamented about the distractions these devices cause in and out of the classroom. Last year, the US surgeon general declared a youth mental health crisis, citing social media as a significant factor, and more than 40 US states are suing Meta, owner of Facebook and Instagram, arguing that the company intentionally manipulated their apps to addict teens and kids. Lees meer
A 2021 survey showed that 76% of US public schools prohibit cellphones. Seven states have implemented bans, and 14 more recently introduced similar legislation.
To parents and educators, it might seem that phones and social media are bad for kids and bad for learning. But research shows that the reality is more complicated, with some suggesting that a blanket smartphone ban isn’t necessarily the solution.
So what are the best ways to approach school phone bans? What do we know about the psychological effects of smartphones on kids and teens? And why does this research tend to defy simple answers?
To answer these questions, guest host and SciFri producer Kathleen Davis is joined by Dr. Emily Weinstein, co-director of the Center for Digital Thriving at Harvard University, and the author of Behind Their Screens: What Teens Are Facing (And Adults Are Missing), and Sandy Roberts, education program manager at Science Friday and former middle school teacher.

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

‘Time Capsule’ Rocks And Earth’s Mantle | Genetically Engineering Stronger Wood
12 september 2024 · 18 min
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. Lees meer
‘Time Capsule’ Rocks Provide Clues About Earth’s Mantle
If 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 Wood
Trees 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 …

To This Neuroscientist, Cows Are Like Puppies
11 september 2024 · 18 min
If you’ve ever seen a cute cow video on social media, you might notice they seem to have a lot in common with dogs. They can wag their tails, they love to gobble down tasty treats, and if you’re lucky, they might flop over for a nice belly or neck scratch. Lees meer
Cows are clearly emotional animals, but how smart are they exactly? That’s the question that neuroscientist and author Dr. Gregory Berns had when he and his wife moved from Atlanta to the Georgia countryside in 2020, and started raising cows of their own. And to better understand them, he applied his years of experience researching the brains of animals, like dogs and dolphins.

Fishing For—And Saving—Sharks | Scientists Identify ‘ManhattAnt’ Spreading Across NYC
10 september 2024 · 18 min
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. Lees meer
Fishing For—And Saving—Sharks off the Jersey Shore
At 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.

Scientists Identify The ‘ManhattAnt’ Spreading Across NYC
New York City is home to more than 8 million people. But there’s another massive population below their feet: ants.
In 2011, when surveying ant populations on Broadway and Times Square, researchers got quite a surprise: an unidentified species of ant, which was soon dubbed the “ManhattAnt.” Since then, it has become the second-most populous ant species in New York City.
Earlier this year, the first study on this unidentified species was released. It concluded…

Using DNA To Boost Digital Data Storage And Processing
9 september 2024 · 18 min
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. Lees meer
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.

An Asteroid Impact, Spotted In Advance | Extreme Heat Is Making Learning More Difficult
6 september 2024 · 25 min
ESA officials said it was only the ninth time an asteroid was spotted before reaching Earth’s atmosphere. And, as the climate changes and summer temperatures linger, educators are increasingly worried about keeping kids safe from heat exhaustion. Lees meer
An Asteroid Impact, Spotted In Advance
On Wednesday, an asteroid named 2024 RW1 burned up in the atmosphere above the Philippines. As asteroids go, it was not especially notable. Astronomers say objects the size of 2024 RW1, which was about a meter in diameter, encounter the Earth about every two weeks. Due to local weather conditions, not many ground observers were able to see the fireball produced by the impact on the atmosphere. But astronomers on the Catalina Sky Survey project had observed the asteroid a few hours earlier as it approached the planet, and were able to give a prediction for where and when it was likely to enter the atmosphere. European Space Agency officials said it was only the ninth time people were able to spot an asteroid in advance of Earth impact.
SciFri’s Charles Bergquist joins guest host Sophie Bushwick to talk about that astronomical event and other stories from the week in science, including work on gold nugget geophysics, a potential advance in pain medications, and the mystery of a missing pregnant shark.
Extreme Heat Is Making Learning—And Teaching—More Difficult
Kids across the United States just kicked off a new school year. But in recent years, summer weather has spilled over into fall, with temperatures staying hotter than normal through September and even into October. Sitting in a sweltering classroom can make learning difficult—and even dangerous.
A recent story in The 19th describes how learning and teaching have become more challenging as the climate heats up. Guest host Sophie Bushwick talks with The 19th reporter Jessica Kutz about her reporting and what solutions might be on the horizon.

Dino-Killing Asteroid Was Rich In Carbon | The Dogs Sniffing Out Spotted Lanternflies
5 september 2024 · 20 min
A new study suggests that the asteroid that killed the dinosaurs may have originated from the outer parts of the solar system. And, invasive spotted lanternflies often lay eggs on vehicles and shipped goods. Now researchers are training dogs to sniff them out before they hatch. Lees meer
Asteroid That Killed The Dinosaurs Was A Carbon-Rich Rock
Around 66 million years ago, an asteroid slammed into the Earth, blasted debris everywhere, plummeted the planet into cold darkness, and ended the age of dinosaurs. (Though birds survived, of course.)
It might be the most famous disaster in our planet’s history, but scientists still have plenty of questions about it. Like, what was the asteroid made of? And where did it come from? A new study in the journal Science offers up some long-awaited answers.
Guest host Rachel Feltman speaks with study author Dr. Mario Fischer-Gödde, a geochemist at the University of Cologne in Germany.
Training Dogs To Stop The Spread Of Spotted Lanternflies
In 10 years, the spotted lanternfly has gone from non-existent in the U.S. to being established in at least 16 states. They’re quite distinct: The adults measure about an inch long, they’ve got striking red and black markings, and are, as the name suggests, spotted. And they’ve got a worrisome tendency to chow down on certain plants, including grapevines, and some fruit and hardwood trees.
Spotted lanternflies are able to spread so effectively in part because they tend to lay eggs on things that travel from state to state: shipping supplies, vehicles, and lumber.
There’s a new tactic to detect spotted lanternfly eggs before they can hatch: training dogs to sniff them out. Guest host Rachel Feltman speaks to two researchers behind this project: Dr. Nathan Hall, director of the Canine Olfaction Research and Education Laboratory at Texas Tech in Lubbock, and Dr. Erica Feuerbacher, associate professor of applied animal welfare and behavior at Virginia Tech in Blacksburg, Virginia.

Why Eels Are So Mysterious—And In Demand
4 september 2024 · 18 min
Eels have fascinated humans for thousands of years, even captivating big thinkers like Aristotle and Freud. Despite having been around for some 200 million years, eels are still rather mysterious creatures. For example, scientists still aren’t sure exactly how they spawn. Lees meer
But those unanswered questions haven’t stopped humans from wanting to eat them. So much so that they’re now endangered in some areas—and a lucrative criminal enterprise has risen up to poach baby eels from the wild.
Guest host Rachel Feltman talks with Ellen Ruppel Shell, author of Slippery Beast: A True Crime History, with Eels about her journey into the wild world of eels.

Webb Telescope Data Point To Six ‘Rogue Worlds’
3 september 2024 · 18 min
Did you know that almost every star you see in the night sky has at least one planet orbiting it? Lees meer
Here’s something even wilder: There are some celestial bodies that look a lot like planets, but just float around freely in the cosmos, unattached to any particular star. They’re called rogue worlds. With data from the James Webb Space Telescope, astrophysicists just identified six right here in our own Milky Way galaxy.
So what can we learn from these rogue worlds? Can they teach us anything about how stars and planets are formed? Guest host Rachel Feltman talks with two authors of the recent study: Assistant Research Scientist Dr. Adam Langeveld, and Professor of Physics and Astronomy Dr. Ray Jayawardhana, both of Johns Hopkins University in Baltimore, Maryland.

Could ‘Season Creep’ Affect Human Behavior?
2 september 2024 · 18 min
You might have noticed that the seasons don’t quite behave like they used to. In some places, fall and spring seem to fly by, while winter and summer are much longer and feel more intense. This shift is known as season creep, where the timing of the seasons starts to shift. Lees meer
This phenomenon is mostly due to climate change creating temperature imbalances and throwing weather patterns off kilter year-round. And it can cause problems for plants and animals as their natural cycles fall out of sync. But what does it mean for human behavior?
Seasonal Affective Disorder, often called seasonal depression, tends to hit during the cold, dark winter months. But as the seasons start changing more quickly and unpredictably, the shift could have a wide range of effects on us that we’re only just beginning to understand.
SciFri guest host Rachel Feltman is joined by Dr. Michael Varnum, social psychology area head and associate professor at Arizona State University, to discuss these questions.

Mosquito-Borne Diseases Are Spreading | ‘Slingshot’ And A Space Mission Gone Wrong
30 augustus 2024 · 24 min
Several states have reported cases of the rare but serious mosquito-borne illness eastern equine encephalitis. And, the new sci-fi movie "Slingshot," about an astronaut’s mental breakdown, prompts questions about how to prepare humans for long-term space travel. Lees meer
Mosquito-Borne Diseases Are Spreading As Temperatures Rise
This week, a New Hampshire man died of eastern equine encephalitis (EEE), a rare but extremely serious disease caused by a mosquito-borne virus. 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. They also tackle other stories from the week in science, including a puzzling result in a dark matter search, how fruit flies change their threat perception during courtship, and investigations into how marmoset monkeys call each other by name.
‘Slingshot’ Imagines A Yearslong Space Mission Gone Wrong
The new movie “Slingshot,” a sci-fi thriller about a yearslong mission to Saturn’s moon Titan, is out in theaters today. It follows the crew members, played by Casey Affleck, Laurence Fishburne, and Tomer Capone, as they start to unravel, highlighting how long, lonely missions can put astronauts’ well-being in peril.

The History Of Teeth, From Ancient Fish To Humans
29 augustus 2024 · 18 min
Your teeth don’t just chew your food—they connect you to the deepest of deep history on Earth. Teeth have existed, in some form, for half a billion years, making them more than 250 million years older than dinosaurs. They came before the evolution of warm bloodedness, eggs, and even limbs. From that very first set of chompers emerged a bewildering and diverse group of teeth, including narwhal tusks, sharks’ pearly teeth, snake fangs, and, of course, ours. Lees meer
Now teeth are the subject of a new book called Bite: An Incisive History of Teeth from Hagfish to Humans. Guest host Maggie Koerth talks with zoologist and author Dr. Bill Schutt about how teeth evolved, why they’re so neat, and what we can learn from studying them.

Errors On Death Certificates May Be Skewing Mortality Data
28 augustus 2024 · 19 min
According to the Centers for Disease Control and Prevention (CDC), the maternal mortality rate in the United States is very high compared to other wealthy countries: About 22.3 maternal deaths per 100,000 live births. This is on par with China and Iran, based on UNICEF data. Lees meer
So why is the US maternal mortality rate so high? It may have to do with how we fill out death certificates.
A study from earlier this year found that misfiling of information in death certificates may be inflating the numbers. The study authors concluded that the US maternal mortality rate was actually half of the CDC-reported rate—about 10.4 per 100,000 live births—which is in line with countries like Canada and the United Kingdom.
But if death certificates can skew maternal mortality statistics by such a huge margin, what else could they be influencing? And how does our system for filling out death certificates work?
To answer these questions, guest host Maggie Koerth is joined by Dr. Robert Anderson, chief of the statistical analysis and surveillance branch at National Center for Health Statistics.

Astronaut Cady Coleman On ‘Sharing Space’
27 augustus 2024 · 19 min
There’s a phenomenon known as the “overview effect,” a changed perspective some people experience after seeing the Earth from space. Retired astronaut Dr. Cady Coleman says that for her, it was a sense of home and connection. Lees meer
“First of all, I just don’t feel that far away,” she said. “I feel like home is bigger than we thought and I just happened to be the one of the furthest out people. But the overwhelming sort of sentiment that I have is if only everyone knew how connected they could be, there’s literally nothing we couldn’t solve.”
Coleman flew on two space shuttle missions, spent 159 days on board the International Space Station, and operated the robotic arm during the deployment of the Chandra X-ray Observatory. Her new book is Sharing Space: An Astronaut’s Guide to Mission, Wonder, and Making Change.
She joins Ira to talk about her experiences in space and some of the challenges she faced in getting to orbit, from selection to training to the problem of obtaining a properly-fitting space suit.

Protecting Sequoias From Wildfire Gets Tricky | Ancient Cave Art And Human Creativity
26 augustus 2024 · 21 min
Sequoia National Park is largely designated as wilderness. That complicates efforts to protect its iconic trees from worsening wildfires. Also, archaeologists keep finding older and older cave art. Here’s what it could tell us about how humans evolved over time. Lees meer
Protecting Sequoias From Wildfire Raises Tricky Questions
Sequoia National Park in California is known for its towering, iconic sequoia trees, some of which are thought to be thousands of years old. Severe wildfires fueled by climate change and a long history of fire suppression have put these trees at risk. One solution to this problem is to plant new sequoias. But an interesting debate has sparked between those in favor of this and those against it.
The vast majority of the park is officially considered “wilderness,” a federal designation that describes an area “untrammeled by man.” This concept of “untrammeled” has become more complicated in the age of climate change: Some people argue that it means humans shouldn’t intervene, even when the ecosystem is changing because of human-made climate change.
Guest host Maggie Koerth speaks with Marissa Ortega-Welch, host and producer of the “How Wild” podcast from KALW and NPR. The first episode of this podcast, “Untrammeled,” highlights this debate.
What Newly Discovered Cave Art Tells Us About Human Creativity
In July, researchers discovered the oldest known cave art. It was found in a cave on the Indonesian island of Sulawesi, and it shows three human-like figures and a wild pig. The painting was dated at 51,200 years old—5,000 years older than any other known cave art.
The finding continues a trend of researchers unearthing older and older examples of human-made art, including those found outside of Spain and Southern France, where most cave art discoveries have been made.

Plastic In Human Brains | Local Anesthetics Recommended For IUD Insertion
23 augustus 2024 · 23 min
A new study measuring microplastics in organs of the recently deceased found that about two dozen brain samples were 0.5% plastic by weight. Also, having an IUD inserted in the uterus is extremely painful for some people. The CDC now recommends that doctors use local anesthetics. Lees meer
Study Finds A Staggering Amount Of Plastic In Human Brains
It only takes a quick look at our streets and waterways to be reminded that plastic pollution is a big problem. But that’s just the plastic that we can see. An increasing amount of scientific literature points to microplastics accumulating inside our bodies, particularly in organs.
A recent preprint published by the National Institutes of Health found a staggering amount of microplastics in livers, kidneys, and brains of recently deceased cadavers. The brains, however, were the biggest shock: They had 10 to 20 times more microplastics than the other organs studied. Twenty-four of the brain samples measured were found to be about 0.5% plastic by weight.
Joining guest host Maggie Koerth is Tim Revell, executive editor of New Scientist based in London. The two discuss this and other top stories of the week, including a possible explanation for an “alien” radio signal, a look into how orb spiders use fireflies to lure other insects, and a study that says playing video games is good for you, actually.
CDC Updates Guidelines For Managing Pain From IUD Insertion
The Centers for Disease Control and Prevention recently announced updated guidelines for managing pain from inserting a popular form of birth control called an intrauterine device, or IUD. The recommendations now advise doctors to consider using local anesthetics like lidocaine to help manage patients’ pain.
An IUD is a small T-shaped device that is passed through the vagina and cervix and placed in the uterus, where it can remain for several years. Figures vary, but this insertion process can be very painful for roughly 10%-20% of patients. In recent years there’s been an …

Don’t Just Walk In The Woods—Touch, Smell, and Taste Them, Too
22 augustus 2024 · 18 min
It’s been a hot and rainy summer in many parts of the US, and it’s been hard to spend as much time in nature as many of us would like. Heat waves and unpredictable weather have sometimes made it riskier to be outside. Maybe you’ve chosen an easier hike, or doubled up on water bottles, or stayed inside when you’d much rather be outdoors with friends and family. Lees meer
If you’ve been feeling apathetic about the outdoors, a new book called Forest Walking, Discovering the Trees and Woodlands of North America might be a helpful read. Co-authors Peter Wohlleben, a forester and conservation advocate, and Jane Billinghurst, an editor, author, and translator, teach readers how to engage with their local forested areas in a deeper way. And it’s what we’re reading for September’s SciFri Book Club.
Diana Plasker, Science Friday’s senior experiences manager, sat down with the authors to talk about how to decode nature’s subtle signs and why it’s important to use all five senses when exploring your surroundings.

Are Space Elevators Really A Possibility?
21 augustus 2024 · 17 min
The space elevator has been a staple of science fiction for decades, from The Fountains of Paradise by Arthur C. Clarke to the Apple TV show “Foundation.” But the work and theories to make it a reality have been in development since the late 19th century. Lees meer
It’s a simple concept: Imagine a long cable, stretching from the Earth’s surface to a satellite locked in orbit 22,000 miles high. It would work like elevators here on Earth, enabling us to send things—and people—up into space. And it would make the need for the expensive rockets we use today obsolete.
Although it has never been considered feasible due to the exorbitant cost and the engineering challenges it poses, the idea refuses to go away.
One of Japan’s biggest construction companies, the Obayashi Corporation, which built the Tokyo Sky Tree, had plans to build a space elevator in 2025 but has reportedly delayed that goal.
So what are the hurdles that keep us from building it? And why does it seem that the space elevator is always 25 years away? Ira Flatow is joined by Dr. Dennis Wright, president of the International Space Elevator Consortium to talk about the feasibility of this megaproject.

Evidence For Liquid Water On Mars | Making Campsite Booking Fairer
16 augustus 2024 · 22 min
Data from the Mars InSight lander points to the presence of liquid water underneath its crust. Also, some national and state parks are changing the way they open up campsite reservations online to make them more accessible to everyone. Lees meer
Scientists Find Strong Evidence For Liquid Water On Mars
Scientists discovered that there could be oceans’ worth of liquid water hidden underneath Mars’ surface. More than 3 billion years ago, Mars had lakes, rivers, and maybe even oceans on its surface. It was very different from the arid red planet we know today.
But the question remains—when Mars’ atmosphere changed, where did all that water go? This discovery could offer up new clues and possibly spur on the search for life on Mars.
Ira talks with Maggie Koerth, science writer and editorial lead for Carbon Plan, about this discovery and other science news of the week, including why the WHO declared mpox a global health emergency, the microbiome of your microwave, a green-boned dinosaur named Gnatalie, and how love is in the air for brown tarantulas.
Releasing Campsite Reservations In Waves Makes Booking Fairer
Back in 2022, Science Friday discussed how campsites in state and national parks were virtually impossible to reserve, unless you had a lot of time on your hands and knew exactly when those reservations were going online. Research had shown that the people able to reserve these sites were often wealthy, educated, and white, leaving lots of other people out of the fun of camping.
But two years later, the same team that found those results says there’s good news: Many state and federal campgrounds have changed how their booking windows work, and as a result, camping has become more equitable.
For example, Saddlehorn Campground near Grand Junction, Colorado, was identified as a campground with an inequitable reservation system in a 2022 study. After its publication, campground managers reached out to the study authors to see how they could do better.

The Promise Of Perovskite Solar Panels
14 augustus 2024 · 18 min
Solar holds great promise as a clean energy solution, as the sun is an incredibly abundant resource, and panels can be placed unobtrusively on roofs and in fields. And solar panel technology has advanced quite a bit over the past few decades: panels have become less expensive, more efficient, and more widely used. Panels also generally fare well, considering that they’re outside in inclement weather year after year. Lees meer
Recent advancements with perovskite solar cells—a type of cell whose name refers to the structure of a compound it contains—have many clean energy enthusiasts excited. Perovskite solar cells are a thin, flexible technology that can even be painted onto a structure and conduct electricity. Much of the work on these has been conducted at the National Renewable Energy Laboratory (NREL) based in Golden, Colorado.
At Science Friday Live in Boulder, Colorado, Ira sat down with two solar experts from NREL, Dr. Joseph Berry and Dr. Laura Schelhas, to discuss perovskite solar cell advancements and the future of this clean energy technology.

An Expert Vegetable Breeder On Innovating Crops For The Future
13 augustus 2024 · 17 min
It’s become clear to farmers and home gardeners alike that climate change is affecting the gardening landscape, literally. The climate is warming, pests are moving into different regions, and there’s a growing need for vegetable varieties that are resilient to the stresses of this new age. Lees meer
In the world of organic farming, the job of creating those new varieties falls to a plant breeder: someone who, often painstakingly, crosses plants until they create a new variety. Dr. Jim Myers, one of the most accomplished plant breeders in the country, has lots of experience with this.
Myers created the Indigo Rose tomato, a strikingly purple variety with the same antioxidants as blueberries. He also created the green bean cultivar predominantly used by Oregon producers, and is debuting two new varieties of low-heat habanero peppers next month, dubbed “Mild Thing” and “Notta Hotta.”
Myers joins Ira Flatow from Corvallis, Oregon, where he’s a professor of agricultural science at Oregon State University. They discuss his decades-long career in plant breeding and what he sees as the biggest challenges for the plant breeders of the future.

What The Private Sale Of Fossils Means For Paleontology
12 augustus 2024 · 17 min
On July 17, Apex the stegosaurus was sold at Sothebys in New York City for a record $44.6 million. The buyer was billionaire Ken Griffin, CEO of the hedge fund Citadel, who says he plans to loan the fossil to American institutions for display. Lees meer
But despite Griffin’s statement, some paleontologists aren’t too happy about the trend of fossils going up for auction.
The sale of dinosaur fossils has become more and more profitable in recent years. Eight out of the ten most expensive fossils have been sold in the last four years. This trend of rising sale prices leaves museums and research institutions unable to pay for fossils that could benefit paleontological research.
Paleontologists fear that as more and more fossils become privately owned, the availability of fossils for research and even access to dig sites might decrease or be restricted.
SciFri guest host and producer Kathleen Davis is joined by Dr. Steve Brusatte, professor of paleontology at the University of Edinburgh in Scotland to talk about the potential scientific impacts of privatizing and selling fossils.

Boeing’s Starliner Leaves Astronauts Stuck On The Space Station
In another blow to Boeing’s Starliner program, which is meant to ferry astronauts and supplies to the International Space Station, NASA announced Wednesday that the troubled spacecraft would not be able to take astronauts Suni Williams and Butch Wilmore back to Earth due to issues with its thrusters.
The two astronauts arrived at the International Space Station in June for a mission that was supposed to last eight days. But with the current problems, the pair might be stuck on the space station, where Starliner remains docked, until early next year. NASA is considering bringing them back in an upcoming SpaceX Dragon mission.
Ira Flatow is joined by Umair Irfan, senior correspondent at Vox, who breaks down this and other top science stories this week, including how the Olympic Games are adjusting to abnormally high temperatures in France, why the EPA banned a widely used weedkiller, and what the moon’s atmosphere is made of.
Could We Get Weather Forecasts Years—Or A Decade—In Advance?
Access to weather forecasts has been made easier than ever with the advent of smartphones. Most of the time, we can get accurate information about weather for the next few hours up through the next few days. But a week or two out, those predictions get less reliable.
In the near future, it may be possible to get accurate weather forecasts weeks, months, or even a decade ahead of schedule. While this sounds like science fiction, researchers at the National Center for Atmospheric Research (NCAR) are working on this very challenge.
Earth system predictions, as the field is called, combines a variety of factors including atmospheric conditions, ocean currents, and even what’s happening in the soil to form predictions. The…

Why Does COVID-19 Spike In Summer?
8 augustus 2024 · 18 min
It may seem like everyone is either getting COVID-19 this summer, or knows someone who has. That’s because for the fourth year in a row, COVID cases are experiencing a summer surge. Lees meer
The CDC now tracks COVID-19 mostly through wastewater and found that viral activity has multiplied more than four times from the beginning of May to now. The CDC classifies the viral activity level as “high.”
So what’s behind this surge? And why does it keep happening in the summer?
SciFri’s John Dankosky talks with Jessica Malaty Rivera, infectious disease epidemiologist and science communicator at the de Beaumont Foundation, about what’s behind the surge and how to stay safe.

Deep-Sea ‘Nodules’ May Produce Oxygen | A Bird’s Physics Trick For High-Altitude Flying
7 augustus 2024 · 23 min
New research suggests that polymetallic nodules found 13,000 feet deep produce “dark oxygen” by electrolyzing water. Also, at higher altitudes, the air is less dense, which makes it harder for birds in flight to generate lift. The turkey vulture has a solution. Lees meer
Deep-Sea ‘Nodules’ May Produce Oxygen, Study Finds
An international team of researchers recently discovered that some 13,000 feet below the ocean’s surface, oxygen may be produced through natural electrolysis. The group found that small lumps called polymetallic nodules at the bottom of the ocean appeared to act as geo batteries, producing enough electricity to break down water and make oxygen.
That observation challenges the idea that photosynthesis is necessary to produce enough oxygen for living organisms. The researchers hypothesize that this could be a source of oxygen for deep-sea creatures. But while it gives some answers as to how life can thrive at the bottom of the sea, it also raises a lot of new questions.
Science Friday guest host and producer Charles Bergquist is joined by the lead electrochemist of the study, Dr. Franz Geiger, the Charles E. and Emma H. Morrison Professor of Chemistry at Northwestern University, to answer some of these questions.
One Bird’s Physics Trick For Flying At High Altitudes
If you’ve ever taken a trip to a higher elevation, you know that the air gets thinner as you go up. If you’re not acclimated to the altitude, it can feel harder to breathe. That thinner air also makes it more difficult for birds and airplanes to fly, because it’s harder to produce the lift forces in thinner air. But it turns out that turkey vultures have a way of dealing with that problem.
Researchers observed turkey vultures in flight at different altitudes and found that rather than flapping harder or more rapidly to deal with decreased lift, the turkey vulture exploits the lower drag in thinner air to fly faster, using increased speed to help balance the lift equation.

Why Cancer Death Rates Have Decreased Over The Last 30 Years
5 augustus 2024 · 18 min
“Cancer” is a dreaded word in the doctor’s office. But about 40% of us will be diagnosed with cancer at some point during our lives, the most common being breast, prostate, and lung cancer, according to the National Institutes of Health. Lees meer
But in the last few decades, major progress has been made in the world of cancer treatment and prevention. Cancer death rates have decreased by about 30% over the last quarter century, with some of the largest decreases seen in lung, melanoma, and myeloma cancers. The Biden administration’s Cancer Moonshot program aims to reduce the number of cancer deaths by at least 50% by 2050.
Early detection methods like mammograms and colonoscopies have improved outcomes for many types of cancer, and new treatment options, like cancer vaccines, immunotherapy, and targeted genetic therapies, have shown promising early results. And the breakthroughs made from the development of the mRNA covid vaccines are bringing even more promise for hard-to-treat cancers.
Dr. Siddhartha Mukherjee, assistant professor of medicine at Columbia University and author of the Pulitzer Prize-winning book The Emperor of all Maladies: The Biography of Cancer, joins guest host John Dankosky to give a broad update on the progress made in cancer treatment and prevention. They also discuss the role AI can play in new breakthroughs, and why some cancers are still particularly difficult to treat.

Hawaiʻi Wildfire Survivors Join Health Study | Wind Turbine Blade Sinks Off Massachusetts Coast
2 augustus 2024 · 20 min
The University of Hawaiʻi study will be the largest of its kind to investigate the health and social impacts of the Maui wildfires. Also, fiberglass is washing up on Nantucket’s shores, and residents are concerned about the long-term environmental impact of this debris. Lees meer
Hawaiʻi Wildfire Survivors To Join Long-Term Health Study
Nearly a year ago, Maui experienced a series of wildfires that caused major destruction and anguish for residents. More than 100 people died and thousands of structures were destroyed in what was the fifth deadliest wildland fire in U.S. history.
Survivors of those fires are now taking part in the largest study of its kind to understand the health and social impacts of the Maui wildfires. The research team will sample the blood, DNA, and urine of participants over at least a decade to see if they develop conditions such as cancer. Researchers say this information will be essential as the island and its residents continue to recover.
Casey Crownhart, climate reporter for the MIT Technology Review joins guest host Kathleen Davis to talk about this story and other top science news of the week, including California’s Park Fire.
Damaged Wind Turbine Blade Sinks Off Massachusetts Coast
A large piece of fiberglass debris from the damaged Vineyard Wind turbine blade has sunk to the ocean floor, as the debris cleanup continues, according to press release from the town of Nantucket that’s timestamped for 9:10 a.m.
Town officials said that about half of the fiberglass shell of the blade remains attached and crews will continue to monitor it until a removal plan is developed. Most of the green and white foam fill dislodged during the initial failure last Saturday.
They added that Vineyard wind is also developing a plan to test water quality around the island.
“This complex undertaking involves engaging experts to determine the best path forward. To conduct the testing, specific information from GE’s Safety Data Sheets is required, which is expec…

The Science And History Of Refrigeration
1 augustus 2024 · 18 min
You know that disappointing feeling when you’re ready to make a delicious meal, but you crack open the refrigerator only to find mushy tomatoes, dried-out bread, or oozing strawberries? Lees meer
Refrigeration fundamentally changes the chemistry of our food, but at this point, most of the United States’ food system relies on the use of refrigerators. Almost three-quarters of the food on an average American’s plate has been refrigerated during production, shipping, and storage. So how did we end up relying so heavily on the fridge? And on a warming planet, can refrigeration keep its cool?
A new book called Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves challenges the definition of “freshness” and our relationship with the fridge. SciFri’s John Dankosky talks with author Nicola Twilley, co-host of the podcast “Gastropod.”
Read an excerpt from Frostbite: How Refrigeration Changed Our Food, Our Planet.

Sodium Replaces Lithium In A New Type Of Battery
31 juli 2024 · 18 min
If nations are to meet their sustainable energy goals, experts argue that batteries will be a crucial part of the equation. Not only are batteries key for many technologies, they’ll also be necessary to meet energy demands with a power grid that is mainly supplied by renewable energy sources like wind and solar. Without batteries, power from those sources can’t be stored for use when the sun isn’t shining or the wind isn’t blowing. Lees meer
Right now, many technologies depend on lithium-ion batteries. While they certainly work well and have revolutionized mobile devices and electric vehicles, there are drawbacks. First, the lithium, cobalt, and nickel they require can only be found in some countries, and there have been accusations of unethical mining practices, including child labor. The mining and production processes also emit a large amount of CO2, and the batteries themselves can explode and cause fires, although these incidents are becoming less common.
A promising, greener solution to our battery needs could be something called a solid-state battery. Lithium-ion batteries conduct electricity through a liquid electrolyte solution, while solid-state batteries do so with solid materials, such as ceramic, glass, and sulfides. This means they have lower risk of fires, charge faster, have higher voltages, and can be recycled. However, their development has taken longer than expected, due to cost, production hurdles, and lack of large-scale, real-world testing.
Earlier this month, teams at the University of Chicago Pritzker School of Molecular Engineering and the University of California San Diego published a paper in Nature Energy demonstrating the world’s first anode-free, sodium-based, solid-state battery architecture, which can charge quickly and last for several hundred cycles. Its main ingredient, sodium, is much more abundant than lithium, cobalt, and nickel, which could mean more affordable and environmentally friendly batteries in the future.

Inside The Race To Save Honeybees From Parasitic Mites
30 juli 2024 · 18 min
Last year, almost half of the honeybee colonies in the U.S. died, making it the second deadliest year for honeybees on record. The main culprit wasn’t climate change, starvation, or even pesticides, but a parasite: Varroa destructor. Lees meer
“The name for this parasite is a very Transformer-y sounding name, but … these Varroa destructor mites have earned this name. It’s not melodramatic by any means. [They are] incredibly destructive organisms,” says Dr. Sammy Ramsey, entomologist at the University of Colorado Boulder.
These tiny mites feed on the bees and make them susceptible to other threats like diseases and pesticides. They’re also highly contagious: They arrived in the US in 1987, and now they live in almost every honeybee colony in the country. Honeybees pollinate many important crops, like apples, peaches, and berries, and their pollinator services add up to billions of dollars.
Ramsey and his lab are trying to put an end to the varroa mites’ spree. Part of their research includes spying on baby bees and their accompanying mites to learn how the parasites feed on the bees and whether there’s a way to disrupt that process.
In Boulder, Colorado, SciFri producer Rasha Aridi speaks with Dr. Ramsey and fellow entomologist Dr. Madison Sankovitz about how the varroa mites terrorize bees so effectively, and what it would take to get ahead of them.

What A Rodent Brain Shows Us About Love | If Colorado Was Flattened, How Big Would It Be?

What A Rodent Brain Shows Us About Love–And Loss Lees meer
Love has the reputation of being a fairly unique human emotion. If we’re lucky, we can experience lots of love in our lives: with romantic partners, children, family, friends. But with love comes the possibility of another, less desirable emotion: heartbreak.
Neuroscientists at the University of Colorado Boulder have found that these feelings seem to actually leave a mark on the brain, with dopamine and other feel-good chemicals flooding to the brain’s reward centers when lovers are reunited.
The source for this data may be surprising: prairie voles, tiny rodents that are among the small percentage of mammals that form monogamous pair bonds. By studying their brains when the voles were united with their mates, researchers were able to pinpoint this dopamine flood that they suspect happens in humans’ own brains under the same conditions.
When the voles were separated for four weeks—long enough for them to consider their pairing “over” and find new mates, the broken-up voles had much more muted dopamine response when reunited. Researchers say that could be good news for heartbroken humans because it shows the brain could have something of a “reset” mechanism that allows individuals to go on and form new bonds.
Joining Ira to talk about this research is Dr. Zoe Donaldson, associate professor of behavioral neuroscience at the University of Colorado in Boulder.
If You Rolled Colorado Out Into A Brownie, How Big Would It Be?
The surface area of Colorado is 104,094 square miles, according to the US Geological Survey, making it the 8th largest state in the country.
But the state, unlike our neighbors to the east, has a lot of extra geographical stuff — like mountains.
One Coloradan who loves to spend time in those big hills wondered if our dear state wasn’t getting a bit short-changed. Denver-based photographer and editor Howard Paul also happens to love baked goods. So when he posed his question to Colorado Wonders…
