Hawai’i’s Mauna Loa Volcanic Eruption Sparing Homes For Now

Hawai’i’s famed Mauna Loa volcano began to erupt this past weekend, after weeks of increasing small earthquakes. So far the flow of lava is posing no risk to homes in nearby Hilo, though that could change rapidly. But in the meantime, an important climate research lab is without power and unable to make measurements. And as lava flows and cools into new rock formations, one unusual product, called Pele’s Hair, looks uniquely soft and straw-like—while being dangerously sharp.

Ira talks to FiveThirtyEight’s Maggie Koerth about the less high profile side effects of a major volcanic eruption. Plus, a new analysis of the magma under Yellowstone National Park, the leadership potential for wolves infected with a cat parasite, and other research stories.

A Nobel Prize For Chemistry Work ‘Totally Separate From Biology’

This year, the Nobel Prize in Chemistry went to Carolyn Bertozzi of Stanford University, Morten Meldal of the University of Copenhagen, and K. Barry Sharpless of the Scripps Research Institute “for the development of click chemistry and bioorthogonal chemistry.” In “click chemistry,” molecular building blocks snap together quickly and efficiently to let chemists build more complicated molecules. But bioorthogonal chemistry takes that work one step farther, allowing the technique to be used within living organisms without damaging cells.

“When someone is thinking outside the box, or in a very different way, we like to think of that as orthogonal thinking,” Dr. Bertozzi explained. “So biorthogonal means not interacting with biology. Totally separate from biology.” Her research began with an interest in developing ways to see specific sugar molecules on the surface of cells. But it has developed into an approach that can be used for advanced drug delivery in fields such as chemotherapy. Bertozzi joins Ira Flatow for a wide-ranging conversation about her research, chemistry education, her early music career, and the importance of diversity in the field of chemistry.

Scientists Discover What Makes Jazz Music Swing

Swing is a propulsive, groovy feeling that makes you want to move with the music. It’s hard to put into words, but if you listen to jazz, you’ve probably felt it yourself. Now, researchers have arrived at a better understanding of what generates that feeling: Their work, published in Communications Physics, focuses on timing differences between a group’s soloist and its rhythm section.

Joining Ira to discuss the new findings are Theo Geisel, a professor of theoretical physics at the University of Göttingen and the Max Planck Institute for Dynamics and Self Organization, and Javier Arau, a saxophonist and the founder and executive director of the New York Jazz Academy.

Consider Empathy For The Yeti Crab (And Other Sea Creatures, Too)

It’s easy to empathize with certain animals: soft fur, big eyes, and family units make it simple to relate to creatures like panda bears, cats, and dogs. Even some undersea critters like dolphins and whales have large fan bases among land-dwelling humans.

But the ocean is filled with many more creatures than just mammals, and many of them fall in the category of “weird.” Defector staff writer Sabrina Imbler thinks a lot about these critters that evade our categorization of “cute.” Things like deep sea worms, jelly-like invertebrates called salps, and the ghostly, hairy yeti crab are Imbler’s bread and butter.

Imbler’s new book, How Far the Light Reaches: A Life in Ten Sea Creatures, is filled with essays comparing aspects of their life to bizarre creatures of the deep sea. From exploring their queer identity through the underwater dance parties of the yeti crab, to grappling with living as a mixed-race person through hybridized fish, each essay is poetic and intimate. SciFri producer Kathleen Davis chats with Imbler from their home in Brooklyn, New York, about the importance of finding empathy with the strangest creatures on our planet.

Advances In Pig-To-Human Organ Transplantation Hold Promise

Earlier this year a pig heart was successfully transplanted into a human for the very first time. Unfortunately, the patient lived for just under 2 months. But it still marks a big milestone in the field of xenotransplantation, or transplanting organs from one species to another.

Scientists are optimistic that advances in pig-to-human organ transplantation could save the lives of some of the over 100,000 people in the waiting for organ donations in the United States.

Ira talks with Dr. Muhammad Mohiuddin, professor of surgery and director of the Cardiac Xenotransplantation Program at the University of Maryland School of Medicine, about what he’s learned in the 10 months since the historic heart transplant, and about the barriers to widespread acceptance of interspecies organ transplantation.

Later, Ira talks with Dr. Megan Sykes, professor and director of the Center for Translational Immunology at Columbia University about how scientists decided that pigs were suitable organ donors in the first place, and the latest advancements in pig-to-human organ transplantation research.

Teaching Your Smart Devices To Get Along

If you’ve ever tried to connect a new Internet of Things device in your home, such as a smart plug or light, you know it can be a complicated process. Not every device works with every other device, and even the most tech-savvy customer may find themself turning to Reddit for help troubleshooting.

These are problems a new Internet of Things standard called Matter aims to solve. Created by a coalition of home device companies, Matter allows devices that run it to speak to each other, set up seamlessly, and communicate securely. The standard officially launched in early November with dozens of new Matter-enabled devices.

Ira talks to Jennifer Pattison Tuohy of The Verge about the problems Matter aims to solve, and some of the practical hitches along the road to a more seamless smart home.

Putting Tap Water To The Test

Every time you turn on the tap, you become the last stop in a complicated journey.

Water from snow and streams collects in lakes and reservoirs, and cities pump it through complex filtration systems to make it pure enough to drink. The particular balance of invisible minerals in each pour from your kitchen tap makes for subtle differences in every glass. One might call it the terroir of tap water.

In a bustling hotel ballroom, surrounded by exhibition booths showing off the latest pipes, pumps and filters, a panel of judges gathered to spot those differences.

I was one of them.

The American Water Works Association assembled a panel of water wonks for its Rocky Mountain regional meeting in the ski resort town of Keystone. Here, we put tap water to the test, blind tasting samples from six cities across Colorado to crown a winner.

Building The World’s Largest Animal Crossing Outside of LA

There’s a spot on Highway 101 in Agoura Hills, it’s pretty inconspicuous. There’s brown and green rolling hills on either side of the highway. Homes are sprinkled here and there. And then a small metal gate that leads off on a hiking trail. You probably wouldn’t know it, but soon this spot will be the location of the world’s largest animal crossing.

This crossing will reconnect habitats that have been cut off from each other for three quarters of a century and it’ll do it over a highway that is constantly buzzing with cars — 300,000 pass by this spot every single day.

In this piece we’re going on a geography voyage — from the north side of the highway to the south, and up the hills, above the highway, to get the real view.

We’ll start here — there’s a big open space on the northern side of the highway. It’s at the entrance to Liberty Canyon and where I meet Beth Pratt.

Over 5,000 Exoplanets Have Now Been Discovered

In March, the NASA Exoplanet Archive logged the 5,000th confirmed planet outside of our solar system. This marks a huge advance since the first exoplanet discovery in 1992, when astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. Now, the Archive contains confirmed sightings of planets in a wide range of shapes and sizes—from “hot Jupiters” to “super Earths”—but they still haven’t found any solar systems just like our own. In many cases, all astronomers know about these distant planets is their size and how far away from their stars they orbit.

The TESS (Transiting Exoplanet Survey Satellite) mission currently in orbit may eventually add ten thousand more candidates to the lists of possible planets. The Nancy Grace Roman Space telescope and ESA’s ARIEL mission, both planned for launch later this decade, could add thousands more. And the James Webb Space Telescope, currently undergoing commissioning, will attempt to characterize the atmospheres of some of the planets astronomers have already discovered.

Astronomer Jessie Christiansen, the NASA Exoplanet Archive Project science lead, joins John Dankosky to talk about what we know about planets around distant suns, and how researchers are working to learn more about these far-off worlds.

Scientists Release The First Fully Complete Human Genome

Two decades ago, scientists announced they had sequenced the human genome. What you might not know is that there were gaps in that original sequence—about 8% was completely blank.

Now, after a years-long global collaboration, scientists have finally released the first fully complete assembly of the human genome. Researchers believe these missing pieces might be the key to understanding how DNA varies between people.

Six scientific papers on the topic were published in a special edition of the academic journal Science.

Ira talks with Karen Miga and Adam Phillippy, co-founders of the Telomere to Telomere Consortium, an international effort that led to the assembly of this new fully complete human genome.

Indigenous Knowledge Is Central To Climate Solutions

As the United States observes Earth Day this year, many will be thinking about their personal relationship with—and responsibility to—the planet. But in an era of multiple planetary crises, including extinctions, global warming, and contaminated water, what about the Indigenous peoples whose millennia-old relationship with their land has been disrupted and sometimes severed by colonialism and other displacements? 

Indigenous environmental scientist and author Jessica Hernandez talks to Ira about the harms the Western science has perpetuated against colonized people, as white environmentalists created national parks on Indigenous lands and “helicopter scientists” continue to do research in the global south while using the wealth of Western institutions. And she explains why greater recognition of Indigenous science, and partnerships that center Indigenous peoples and their research questions, is good for the entire planet.

Prizes For Science That Makes You Laugh, Then Think

Prizes went to researchers for analyzing what makes legal documents unnecessarily difficult to understand. And for creating a moose crash-test dummy. And for explaining, mathematically, why success most often goes not to the most talented people, but instead to the luckiest.

If that sounds like a strange set of awards—that’s because it’s the Ignobel Prize Ceremony. This year, for the 32nd year in a row, laureates gathered (virtually) to be recognized for their unusual contributions to the world of science and engineering. In the words of Marc Abrahams, editor of the Annals of Improbable Research and awards ceremony ringleader, “It’s not about good or bad. If you win an Ignobel Prize, it means you’ve done something that will immediately cause anyone who hears about it to laugh, and then to think about it for the next few days or weeks.”

Abrahams joins Ira to talk about the backstory of the awards, and to introduce some highlights from this year’s online prize ceremony.

The Science Behind Your Favorite Thanksgiving Dishes

Thanksgiving is right around the corner, and for many people, that means it’s time to start thinking about what will be on the menu for dinner that night. Many people will opt for a classic turkey: others, a vegetarian-focused meal. Regardless of the plan, preparing food for the holiday can take some planning, and there’s a lot of science that goes into it.

Cookbook author Kenji López-Alt thinks about the science behind cooking a lot. He’s the author of The Food Lab: Better Home Cooking Through Science, and he lists Thanksgiving as his favorite holiday. That makes him the expert on all things brine, sides, and pie. López-Alt joins Ira from his home in Seattle, Washington, to answer questions about the science behind Thanksgiving foods.

NASA’s Massive Rocket Finally Launches To The Moon

Early Wednesday morning the Artemis 1 mission launched, the first integrated flight test of NASA’s Space Launch System—a massive rocket that NASA hopes will enable an eventual lunar landing. The uncrewed launch was a long time coming. Elements of the program have been under development for over a decade. If all goes according to plan, a second Artemis flight—this time, with crew—will take place in 2024, with a crewed lunar landing in 2025.

Another component of the program, a tiny spacecraft called Capstone, entered into lunar orbit several days prior to Artemis. It will test a complicated orbit planned for a potential lunar space station called Gateway, which would serve as a way station for astronauts moving between Earth and the Moon.

Ira talks with Jim Free, NASA’s Associate Administrator for Exploration Systems Development, and Brendan Byrne, space reporter for WMFE and host of the Are We There Yet podcast, about the test flight and what lies ahead for the Artemis program.
