- Meet the tiny, see-through fish that can regenerate its brain
Move over, Drosophila. Step aside, C. elegans. Scientists are working to establish a new model organism. It’s a tiny species of glassfish called Danionella cerebrum, and its claim to fame is that it's almost completely transparent and can regrow parts of its body, including its brain. Scientists…
- Why is everyone so obsessed with protein?
It’s impossible to ignore the latest nutrition trend: protein-maxxing. Stroll through the grocery store and you’ll find protein chips, protein-packed ice cream, and even sparkling protein water. Not to mention the FDA’s new upturned food pyramid, which puts steak and a roast chicken at the top…
- What a trapped antimatter particle could tell us about reality
Almost all matter particles have corresponding particles of antimatter: Protons have antiprotons, neutrons have antineutrons, and so on. When matter and antimatter bump into each other they destroy each other and release energy. With carefully manipulated magnetic fields, however, it’s possible to…
- Why are armadillos moving up north?
Armadillos have been crawling up the southern U.S. as the climate warms, making themselves at home as far north as Kentucky and Indiana. They’re what wildlife biologists call a “signal species,” one whose presence or absence tell us something about how an ecosystem is changing.Host Flora Lichtman…
- When, and where, did bats first take to the sky?
A consortium of researchers from around the world has sequenced the genomes of 103 bat species, tracing the evolutionary origin of bats back in time. Using both genetic samples and fossil records, the researchers place the earliest bats as arising in Europe some 60 to 65 million years ago. The…
- People are microdosing GLP-1s for weight loss. Is it safe?
There’s a new trend in the world of weight loss: microdosing GLP-1 drugs. Online health clinics are promising big results with microdoses drugs like Ozempic, Wegovy, and Zepbound. Many source their drugs from compounding pharmacies, which can get complicated because compounding pharmacies are able…
- Terence Tao on how AI math solutions miss the point
In a matter of months, AI has transformed the field of mathematics. In September, OpenAI claimed that an AI model solved the million-dollar Navier-Stokes equation. Then, a few weeks later, OpenAI shared results for more than 350 previously unsolved math problems. The news has prompted an…
- What was life like for Tyrannosaurus rex?
While Tyrannosaurus rex has reached celebrity status in pop culture thanks to movies like “Jurassic Park” and famous fossils, it can be difficult to imagine what everyday life was like for this charismatic prehistoric predator. Producer Kathleen Davis speaks to science writer Riley Black, who has…
- Isabella Rossellini on how acting connects to animal cognition
Pass the cocktail napkins and refill your glass because we’re having a dinner party. You’ll be between Isabella Rossellini, the Italian model, movie star, and director; and ecologist Carl Safina, author of many books, including “Beyond Words: What Animals Think And Feel."This might seem like an…
- Why are we changing the way we keep time?
The time we see on our phones and clocks is based on the Earth’s rotation. But that rotation speed varies, so if it speeds up or slows down, our time measurements get thrown off. To solve this problem, timekeeping scientists have been deploying leap seconds to keep our clocks aligned with our…
- Kazuo Ishiguro on emotional truth in sci-fi and in our AI reality
The movie “Klara and the Sun,” in theaters now, is based on the 2021 novel of the same name by Kazuo Ishiguro. The story is set in the future and is narrated by Klara, a robotic “Artificial Friend,” whose job is to be a companion to a sick teenage girl.In the 5 years since the release of the…
- Is that garbage can bear resistant? These bears will find out
Have you ever wondered what it means for something to be bear resistant? How do manufacturers know that the cooler you take camping or the compost bin in your backyard will keep hungry bears out? Wonder no more! Journalist Alex Davies’ new book “Kobuk the Destroyer: And Other Tales from the Wild…
- Jennifer Doudna on what it takes to be a good scientist
In 2020, Jennifer Doudna shared the Nobel Prize in chemistry for the development of the gene-editing technique CRISPR. Along with related techniques, it has become an essential tool in genetics, allowing specific sections of genetic code to be cut and replaced in a genome. It’s an advance that has…
- Getting the billion-dollar PRIMA space telescope off the ground
In late September 2026, NASA announced that a new telescope called PRIMA was getting a green light and advancing to something called Phase B of the development process. But what does that mean exactly? How does a billion-dollar space project get thought up, designed, approved, and…
- Ayana Elizabeth Johnson on making climate action cool
Ayana Elizabeth Johnson is one of the most prominent voices in the climate movement. She’s a marine biologist by training, but as she saw the effects of the climate crisis intensify, she took on more public-facing advocacy work.Her work is expansive: She helped organize the March for Science, she…
- Could a whale swallow a human, 'Whalefall' style?
In the new movie “Whalefall,” a scuba diver (Austin Abrams) gets accidentally swallowed by a sperm whale. What follows is a tense battle against time and the whale’s digestive system, to escape before his air supply runs out. But could a whale actually swallow a human? And how might this play out…
- Why do politicians talk like that?
With the midterms approaching, politicians are out in full force to convince voters to elect them. And that means that we’re hearing a lot of “politician speak.” You know it when you hear it: those folksy turns of phrase, the vague promises. But what do linguists have to say about this vocal…
- Sargassum superblooms are choking coastlines around the Atlantic
An unwelcome visitor is arriving on beaches from West Africa to the Caribbean, and Brazil to Florida. It’s brown, it’s stinky, and it’s more abundant than ever: sargassum. This free-floating seaweed has become a major problem for coastal ecosystems, communities, tourism, and infrastructure. So…
- Celebrating Ada Lovelace Day and the women who made the internet
This year, October 13 marks Ada Lovelace Day, an observance that calls attention to the role of women in computing and technology. In this conversation from 2018, Ira talks with Claire Evans, author of “Broad Band: The Untold Story of the Women Who Made the Internet,” about some of the women who…
- Are attachment styles more than a social media trend?
In the past few years, the idea of attachment styles has taken off, both online and in therapy offices. It’s gone from a niche psychological concept to a shorthand to describe how we show up in relationships. Here’s a crash course: Anxious attachment is when you seek constant reassurance. Avoidant…
- The science and politics of the new mRNA flu vaccine
A new mRNA flu vaccine made by Moderna was approved by the FDA in August, and is currently available for people aged 50 and over. The promise of an mRNA vaccine for flu is that it can be spun up more quickly than a traditional vaccine, meaning it could better match the flu strain that’s…
- What is the Kelvin wave on the West Coast?
A Kelvin wave has reached California and is creeping up the West Coast, raising both sea levels and concerns from government officials. This kind of massive internal wave begins in the western Pacific Ocean and then travels eastward to the Americas along the equator, and then up and down the…
- The punk rock life of cephalopods
Cephalopods have a reputation for being smart and majestic. And while that may be true, the life of a cephalopod can also be dark and gritty. Have you heard of octopus death spirals? How about cephalopod cannibalism? Host Flora Lichtman is joined by cephalopod experts Heather Judkins and Z. Yan…
- The Nobel winner searching for deep-space neutrinos in Antarctica
It’s Nobel Prize week, and this year's prize in physics went to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.” The IceCube is a massive neutrino detector that covers a cubic kilometer of Antarctic…
- How important ideas get reawakened, with David Byrne
On Science Friday, we love to talk about ideas, especially ideas that have the power to shape the future. But there are plenty of groundbreaking ideas that almost don’t make it out of the lab or the art studio: ideas that are birthed but then fall into a deep slumber until, years later, they’re…
