Horror stories (especially movies) have a tradition of long series capstoned by an “ending” movie. Halloween Ends. Friday the 13th: The Final Chapter. THE Final Destination. And while Third Pod isn’t a horror movie, we are ending (but like some of those stated “final” movies, we may someday return). Join hosts Shane Hanlon, Vicky Thompson, and a special guest, to reflect on the highs, and the highs (of course there weren’t lows!) of the podcast over the years, and what it has meant to them.

There’s something powerful about the sound of a scream. Whether it pierces the silence of an empty building or rings out through a crowded room, it forces you to stop what you’re doing and take note. It turns out there’s a scientific explanation for that. Our brains are hardwired to recognize the sound of a human scream as a distress signal so that we can respond accordingly. We talked to neuroscientist Luc Arnal about what particular sounds make a scream a scream and how he studies the brain circuits that interpret them.

Carolyn Elya is the Zombiologist in Chief, aka incoming Assistant Professor in Molecular and Cellular Biology at Harvard University. She’s been obsessed with parasites for a while, but it was the flies zombified by a fungus that made them climb, perch, and die that really caught her fancy. We talked with Carolyn about how fungi control flies and other insects, and the evolutionary implications for the zombie-making fungus and its doomed victims.

One of the scariest things for scientists is watching entertainment media portray your field of study inaccurately—the horror! Flood resilience officer and social volcanologist Jazmin Scarlett turned her hobby of playing video games into a paper discussing the depictions of volcanic hazards in games such as Pokémon, LEGO DC Super Villains, and Shadow of the Tomb Raider. The typical video game volcano nearly always has molten lava, but would these games be even more fun to play if they incorporated fissure eruptions, pyroclastic flows, and the dangerous effects of ash and toxic gasses? Jazmin talked with us about her views on natural disasters in fiction media, what scares her about volcanoes, and why she left volcanology to work on flood resilience with the UK’s Environment Agency.

The video game and TV show “The Last of Us” captivated audiences with the concept of a fungal pandemic. The story is set in a world ravaged by a fungus that infects people and turns them into zombies. But what’s the likelihood a human fungal pandemic could happen? Scientists Teresa O’Meara and Tim James separate fungal fact from fiction and talk about what real fungal fears keep them up at night.

We're diving into the intriguing world of vampire bats and their unique genetic adaptations to a blood-based diet. Shenglin Liu is a researcher at the Senckenberg Natural History Museum in Frankfurt, Germany tells us that vampire bats have evolved specialized traits, from teeth modifications to brain enhancements, to thrive on a diet of blood. The episode also explores the surprising social behaviors of these bats, including blood-sharing among friends, shedding light on their intelligence and adaptability. You will get a picture of these "cute, blood-sucking, smart, and generous bats" and the remarkable feats of evolution that make them stand out in the animal kingdom.

It’s that time of year again! For many of us, temperatures are cooling, leaves are changing, Pumpkin Spice Lattes are…latte-ing. While that all sounds lovely, it’s also spooky season, and we’re celebrating with a special series we’re calling, Tales from the (manus)crypt. Get it?! It’s like Tales from the crypt but with science! Join us in the coming weeks to hear the stories about vampire (bats), (fungal) zombies, volcano (horror), and more!

As a young child in India, Nithin Silvadas picked up Carl Sagan’s Cosmos, and it may have changed his life. From that moment on, he was enraptured with they universe. An undergraduate in engineering (where he literally helped build satellites) and PhD focused on radiation belts around planets (including Earth) later, he’s now a Research Scientist with NASA Goddard studying space weather. Wait, what’s space weather? We talked with Nithin about plasma fields, how social class affects science, and who science really should serve.

What goes up must come down, right? Well, what if things go up and come down slightly slower than you might expect? Are there balloons attached? Filled with helium? Are you on Venus? Probably not, but the planet does have a similar gravity to Earth and its planetary scientist Gael Cascioli’s job to learn about gravity, specifically gravitational waves, on Venus and beyond. We talked with Gael about an upcoming mission to Venus, the importance of diverse collaborations, and why we shouldn’t put some much emphasis on the “publish or perish” model.

If you’re a scientist in an oceanography department, you’re probably studying the ocean, right? Well, part of your job might be studying things like phytoplankton, the tiny oceanic powerhouses that play a crucial role in our planet's ecosystem. But how about clouds? Oh, and the properties of light, too? Wait a minute… Atmospheric scientist Kirk Knobelspiesse sat down with us to talk about how atmospheric aerosols interact with clouds, the intricate dance of light and its polarization, and what it’s like to look up when everyone else is looking down. This episode was produced by Shane M Hanlon, and mixed by Collin Warren. Artwork by Karen Romano Young. Interviews conducted by Jason Rodriguez.
What was the first big project you worked on at your job? An important report? An interesting experiment? How about helping to build a satellite? Ashley Greeley, research scientist in the Heliophysics Division at NASA Goddard Space Flight Center, joined us to talk about becoming an expect in talking about imposter syndrome, building innovative devices that measure radiation from space weather, and how stubbornness can be an asset for a budding scientist. This episode was produced by Shane M Hanlon, and mixed by Collin Warren. Artwork by Karen Romano Young. Interviews conducted by Jason Rodriguez.
When you look up into the night sky, what do you see? Is it a clear picture? Do you see anything at all? What if we could enhance our view of the cosmos and develop technology that promises to clear away cosmic blur? We talked with astrophysicist and nuclear engineer Priya Ghosh, a postdoctoral researcher at NASA Goddard Space Flight Center, who builds and develops radiation detectors to detect neutrons and gamma rays, and also studies and analyzes cosmic ray data to understand better the chemical composition of the galaxy. We chatted with her about changing the narrative on nuclear energy, writing magical realism fiction, and trying to build a good pair of eyeglasses so the galaxy becomes less blurry.

What do Antarctica, Nepal, South Korea, and rural NE Pennsylvania all have in common? They’re all places where Doug Goetz of UC Boulder’s Laboratory for Atmospheric and Space Physics has done fieldwork. From releasing balloons next to an active Air Force base and being followed by helicopters, to close calls with a milk truck turned mobile lab and being extracted from a foreign country after an earthquake, we talked with Doug about why fieldwork is a crucial, and perhaps misunderstood, part of the scientific endeavor. This episode was produced Shane M Hanlon and mixed by Collin Warren. Artwork by Jace Steiner.
The mountains are calling! But the trail to get there is pretty bumpy…can everyone come along? When we imagine a geologist striding through the mountains, carrying heavy samples and equipment, the picture omits a lot of people. Scientists with mobility, vision and hearing impairments or other disabilities have a much longer road to walk to get to the field sites geologists often seek. We talked to Anita Marshall, a researcher and advocate for accessible field courses about innovative practices for bridging the gap between remote field sites and curious scientists who may not be able to easily reach them in person.

Many of us know that tree rings can tell us how old a tree is. But there’s so much more we can learn from these seemingly simple lines. In the mid 1800’s, right before the start of the U.S. Civil War, North America began to experience unusually low rainfall that lasted approximately 10 years. This drought, on par with the Dust Bowl of the 1930’s, may have played a role in the near extinction of the American Bison due to the migration of people to areas that were lusher and more conducive to farming. Max Torbenson, formerly a postdoc at The Ohio State University in their Civil Engineering Department, now a Research Associate at the Johannes Gutenberg University of Mainz, studied tree rings to learn about past environments and climates. While he admits that it’s difficult to attribute the effects of the drought to altering any specific part of the Civil Wars, reports do describe issues in supply chains due to rivers drying up and shortages of water for troops and animals used for transportation. In the latest episode of AGU’s podcast Third Pod from the Sun, Max describes how the work he and others are doing can inform us about how climate change has been influencing wildlife and humans for hundreds of years. Listen as Max recounts his journey as a scientist, takes us to remote field locations full of danger, and fills us in on why he fell in love with U.S. This episode was produced Shane M Hanlon and mixed by Collin Warren.

You might think of a deserted island when you picture being marooned, but for some geology researchers the island is their research ship. To collect samples of rocks and sediments from deep beneath the ocean, scientists park a ship called the JOIDES Resolution in place out at sea. That gives them plenty of time to drill for their samples, but it also means spending two months offshore. We talked with Luan Heywood, a marine science technician who sails for six months a year on the JR and with Ally Peccia, a grad student who sailed on a two-month expedition, about the science they do on the ship and how they felt about their time at sea.

Every year between June and November, researchers take to the skies to better understand and measure hurricanes. Heather Holbach is part of NOAA’s Hurricane Research division and is one of the scientists on the flight team who gets up close and personal with hurricanes. Flying directly into the eye of the storm gives her insight and information, that tracking the storms on the ground doesn’t. This field work is essential for informing forecasting models and the response on the ground. This episode was produced by Katrina Jackson and mixed by Collin Warren. Artwork by Jace Steiner.
Seismologist Margaret Boettcher has ventured to the depths of South African gold mines and the middle of the Pacific Ocean in a quest to find earthquakes that are predictable enough to measure and simple enough to understand. Performing fieldwork in these locations presents unusual challenges, such as being so crammed in an elevator shaft with miners that Margaret’s feet couldn’t touch the bottom, and dredging rocks from the seafloor using a bucket on a 3.5-kilometer-long cable. On Margaret’s most recent series of expeditions to the Gofar transform fault 1,500 kilometers west of the Galapagos Islands, she and many of her team members couldn’t even join the cruises due to the COVID-19 pandemic. Instead, they worked out ways to participate remotely, which had the added benefit of opening up the research to more people. This episode was produced by Katrina Jackson and mixed by Collin Warren.

It’s that time of year again where many scientists head out into the field, from far-flung locations to local backyards. In recognition of the lengths that some scientists go to to get answers to questions that only the field can provide, we’re sharing stories of science from quaking earth, to roaring winds, to choppy seas, and beyond! And, as a special treat, head over to our newsmagazine Eos for their special issue this month, Out of office, featuring some of our interviewees talking about their fieldwork experiences.

Wildfires seem to be happening more often, and in 2020, Colorado experienced the worst fire season in its recorded history. Extreme fire events are often assumed to be caused by climate change, but it is not immediately clear this is the case. Heat, humidity, precipitation and wind speed all play a role in fire risk, and the exact way that these factors combine changes from day to day. Forest management practices and increased human activity in high-risk areas can also increase fire risk, and this makes it more challenging to pinpoint the reason why more fires are occurring. Colorado State University professor Dan Cooley has used multivariate statistical analysis of Fire Weather Index data to demonstrate that climate conditions in northern Colorado have changed in ways that make fires more likely to occur there – even if it is often impossible to attribute individual fires to this climactic shift.

The different temperatures humans experience can be as localized as the variance from a suburban area to its urban center. The urban heat island effect - UHI for short - is one such danger. Cities are hotter due to concrete and asphalt absorbing and retaining heat, less tree cover, AC units pumping out hot air, and more. Most worrying is how hot it remains at night, when bodies are trying to cool down and recover from hot daytime temps. Scientists like Angel Hsu are using data collected by satellites and citizens to translate these urban effects into numbers policymakers can use when leading climate change mitigation efforts on local levels.

We all know the saying “history repeats itself” but to what extent is that true when it comes to Earth’s climate? In order to understand and even predict future climates, transitions from one historical climate state to another can be mathematically modeled by atmospheric scientists like Dr. Matthew Huber. However, there’s something special about how anthropogenic climate change is impacting climate transitions, and it’s Dr. Huber’s job to capture this oddity with math!

We’ve all probably heard about how climate change is affecting the ice sheets and polar bears, but what about human health? More severe and numerous floods, droughts, and heat waves impact a wide range of health outcomes, and shifting biomes may spread diseases to new places. How do scientists understand which portions of health effects are caused by climate change, and how can health organizations be prepared? To find out, we talked with Kristie Ebi, who founded the Center for Health and the Global Environment (CHanGE) at the University of Washington. In addition to the effects of climate change, Kris told us about how many of the mitigations for climate change—e.g. switching from coal to renewable power sources, creating more environmentally-friendly transportation systems, and reducing meat in our diets—will coincidentally improve public health. She also introduced us to the rap stylings of Baba Brinkman, whose song “Climate Hero” summarizes several of the points Kris made in our episode. This episode was produced by Katrina Jackson and mixed by Collin Warren. Artwork by Jace Steiner. Find a companion to this episode from our friends over at Carry the Two. “Climate Hero” and other science raps by Baba Brinkman will be released via Spotify and other streaming services soon on a forthcoming science rap album, which can be previewed here: https://music.bababrinkman.com/album/rapsode.
Jane Baldwin is a storm chaser, only her mode of chasing is computational modeling using multiple streams of data. As an Assistant Professor of Earth System Science at UC Irvine, she models how hurricanes and other natural hazards respond to atmospheric dynamics. We talked to Jane about the challenge of forecasting not just the damage to buildings from cyclones, but also the economic and social impacts. And how climate change factors into the outcomes.

The Earth's oceans play a crucial role in regulating the planet's climate by absorbing and storing vast amounts of heat and carbon dioxide from the atmosphere. However, due to human activities such as the burning of fossil fuels and deforestation, the oceans are warming at an alarming rate. This increase in ocean temperature is causing a range of devastating impacts, from more frequent and severe storms to rising sea levels and bleached coral reefs. To better understand the complex interplay between ocean warming and its impact on land, scientists like Maike Sonnewald are using climate models to simulate and predict changes in ocean currents and temperatures. These models allow researchers to analyze how different factors, such as greenhouse gas emissions, ocean circulation patterns, and solar radiation, influence ocean warming and its effects on the Earth's climate system. Through these efforts, scientists hope to develop strategies to mitigate the harmful consequences of ocean warming and protect vulnerable communities and ecosystems.
