How will future forests survive climate change?

Forests are the lungs of our planet. Not only do they absorb carbon dioxide and create oxygen, they also regulate temperature, absorb rainwater to help prevent flooding, and provide critical habitat for the majority of the world's land-based plant and animal species.But due to land conversion for agriculture and road construction, timber harvesting, and increasing wildfires, the trees that make up our forests are increasingly endangered. That's why we need reforestation: replanting new forests to replace the old ones.For the past century, the United States Forest Service has helped to replant new forests and manage existing ones. But as scientists face the ongoing threat of climate change, they're developing new strategies... including one that tries to literally predict the future.Learn more about sponsor message choices: [podcastchoices.com/adchoices] (https://podcastchoices.com/adchoices) [NPR Privacy Policy] (https://www.npr.org/about-npr/179878450/privacy-policy) ...

The science behind the FDA ban on food dye Red No. 3

On Wednesday, the Food and Drug Administration announced it is banning the dye called Red No. 3, a food dye additive in many processed foods, like sodas, sweets and snacks. Recently, it and other dyes were linked to behavior issues in children. But high levels of Red No. 3 were linked to cancer in rats decades ago. So why is the ban happening now? Senior editor and science desk correspondent Maria Godoy answers our questions about Red No. 3 and other dyes that may replace it. Plus, how should parents think about feeding their kids products that may contain Red No. 3 before the ban takes affect.Questions, story ideas or want us to dig into another food science issue?

All of life has a common ancestor. What was LUCA?

Imagine the tree of life. The tip of every branch represents one species, and if you follow any two branches back through time, you'll hit an intersection. If you keep going back in time, you'll eventually find the common ancestor for all of life. That ancestor is called LUCA, the last universal common ancestor, and there is no fossil record to tell us what it looked like. Luckily, we have Jonathan Lambert. He's a science correspondent for NPR and today he's talking all things LUCA: What we think this single-celled organism may have looked like, when it lived and why a recent study suggests it could be older and more complex than scientists thought.

Some Dinos Had Feathers. Did They Fly?

When you picture a dinosaur, what does it look like? For [Jingmai O'Connor] (https://paleontologista.com/) , paleobiologist and associate curator of reptiles at the Field Museum of Chicago, the dinosaurs she studies look a lot more like birds."If you looked at an artist's reconstruction of something like Velociraptor or Microraptor ... you would see that it pretty much looks the same as a bird," Jingmai says. "In terms of the plumage, the soft tissues covering the body, it would have looked very, very birdlike."In this episode, Short Wave delves into the dinosaur-avian connection. Which dinosaurs had feathers? Were they using them to fly? And once and for all – what are those ancient dinosaurs' relationship to birds today? Have other dinosaur questions you want us to unravel?

Bone Marrow Cells: Key To Vaccine Longevity?

The COVID-19 mRNA vaccine generates enough of an antibody response to protect against severe disease for six months. But other vaccines offer years-long — even lifelong — immunity, such as the measles or yellow fever vaccines. Is there a way for scientists to tell how long a person's immunity will last? A team at Stanford Medicine might have found a way to do just that — with the help of some of the cells found in our bone marrow. Questions about vaccines or the respiratory season?

The Science Behind Wildfire Smoke

Air quality in the Los Angeles region has plummeted due to smoke from the ongoing wildfires. With all that smoke comes possible risks to human health. So what actually is smoke and why is it so harmful? [Jessica Gilman] (https://csl.noaa.gov/staff/jessica.gilman/) , an atmospheric chemist with the National Oceanic and Atmospheric Administration, explains what smoke is made of, how it behaves in the atmosphere and smoke's role in climate change. Plus, tips for how to lessen your exposure. [Check out] (https://www.cdc.gov/wildfires/safety/how-to-safely-stay-safe-during-a-wildfire.html) the CDC's recommendations for avoiding smoke inhalation here.

What Are California's Santa Ana Winds?

Over 29,000 acres in the greater Los Angeles area are on fire right now. The fires emerged after the Santa Ana winds swept into the Los Angeles area Tuesday. The largest is the Palisades fire, which is quickly burning through the Pacific Palisades and Malibu communities. It's one of four ongoing critical fires — only one of which is partially contained. Ahead of the windy week, a [Red Flag Warning] (https://www.weather.gov/mqt/redflagtips) was issued for an increased fire risk due to the strong winds, low humidity and higher temperature. Today, we dig into the Santa Ana winds: What they are and how they combined with other factors to create conditions for the most destructive fire in Los Angeles' history.

Fluoride: Fact vs. Fiction

Fluoridating the public water supply has been common practice for nearly 80 years in the U.S. It's an acclaimed public health intervention that helps prevent cavities. For just as long, some have raised concerns about the practice that can veer from evidence-based to unsubstantiated conspiracy. An analysis by government researchers, published Monday in [JAMA Pediatrics] (https://jamanetwork.com/journals/jamapediatrics/fullarticle/2828425) , is adding to the debate. The research found that exposing babies and kids to high levels of fluoride might be associated with neurodevelopmental harm. Frankly, it's a lot to digest — so we invited health correspondent [Pien Huang] (https://www.npr.org/people/729920828/pien-huang) onto the show to wade through the debate.Questions, story ideas or want us to dig into another public health debate?

How Two Veterans Developed The Same Rare Brain Condition

Some weapons used by the U.S. military are so powerful they can pose a threat to the people who fire them. Today, we meet two Marines, William Wilcox and Michael Lozano, who spent years firing missiles and rockets, then developed the same rare brain condition: arteriovenous malformation, or AVM. The condition sends high pressure blood from a tangle of abnormal blood vessels directly into fragile veins, which can leak or burst. Most AVMs are caused by genetic changes that affect the growth of blood vessels, so the connection between weapon blasts and AVM isn't always immediately clear. But NPR's brain correspondent Jon Hamilton reports that recent research suggests that blast waves can alter genes in the brain — and that the evidence is even stronger for less extreme blood vessel changes.Have questions or story ideas?

The Dubious World's Largest Snowflake Record

Snowflakes. These intricate, whimsical crystals are a staple of magical wintry scenes, but how big can they really get? Well, according to the Guinness World Record keepers, the " [largest snowflake] (https://www.guinnessworldrecords.com/world-records/73325-largest-snowflake) " ever recorded was a whopping 15 inches in diameter. It was spotted near Missoula, Montana in 1887. But [Kenneth Libbrecht] (https://www.its.caltech.edu/~atomic/) , a physicist at Caltech, has long been skeptical of that record. So he set out to find what makes a snowflake a snowflake and whether that 1887 record is scientifically possible. You can read more about what he discovered [here] (https://www.npr.org/2023/12/25/1217356234/just-how-big-can-a-snowflake-get-it-depends-on-what-you-mean-by-snowflake) .

The Trouble With Zero

Happy New Year, Short Wavers! What better time to contemplate the conundrum that is zero than this, the reset of the year? Zero is a fairly new concept in human history and even more recent as a number. It wasn't until around the 7th century that zero was being used as a number. That's when it showed up in the records of Indian mathematicians. Since then, zero has, at times, been met with some fear — at one point, the city of Florence, Italy banned the number.Today, scientists seek to understand how much humans truly comprehend zero — and why it seems to be different from other numbers. That's how we ended up talking to science writer [Yasemin Saplakoglu] (https://www.yaseminsaplakoglu.com/) about the neuroscience of this number that means nothing. [Read more] (https://www.quantamagazine.org/how-the-human-brain-contends-with-the-strangeness-of-zero-20241018/) of Yasemin's reporting on zero for Quanta Magazine.

Bird Backpacks Could Help This Parrot Bounce Back

The thick-billed parrot is the only surviving parrot species native to the United States. These brightly colored birds once roamed across the American Southwest and as far south as Venezuela — but today, the only wild population remaining lives high in the forests of Mexico's Sierra Madre mountains. For years, conservation organizations like OVIS ( [Organización Vida Silvestre] (#OrganizaciónVida Silvestre) ) and the [San Diego Zoo Wildlife Alliance] (https://sandiegozoowildlifealliance.org/) have been working on a multi-faceted conservation project to save these birds. Host [Regina G. Barber] (https://www.npr.org/people/1082526815/regina-g-barber) and producer [Rachel Carlson] (https://www.npr.org/people/1112796909/rachel-carlson) dive into the details of that project — and how tiny "bird backpacks" are helping to make it all happen.

The First Woman To Get A New Kind Of Kidney Transplant

Towana Looney became the first living person in the world to get a kidney from a new kind of genetically modified pig last month. Health correspondent [Rob Stein] (https://www.npr.org/people/146944972/rob-stein) got exclusive access to be in the operating room.Towana is a 53-year-old grandmother from Gadsden, Ala. She's been on dialysis for four hours a day, three days a week since 2016. Her immune system would reject a human kidney. So the Food and Drug Administration made an exception to its usual clinical study requirements to allow Looney this new kind of pig kidney. But the procedure is controversial.

Why Big Tech Wants Nuclear Power

AI uses a lot of power. Some of the next generation data centers may use as much power as one million U.S. households. Technology companies like Microsoft, Google, Amazon and Meta hope nuclear power will offer a climate solution for this energy use. Nuclear power plants can deliver hundreds of megawatts of power without producing greenhouse gas emissions. But some long-time watchers of the nuclear industry are skeptical that it's the right investment for big tech companies to make.

How Racism – And Silence – Could Hurt Your Health

Racism is often covered as a political, cultural, or news story. But how is it affecting people's health? That's the question [Cara Anthony] (https://www.kff.org/person/cara-anthony/) , a KFF News reporter, wanted to answer: not just on an individual scale, but on a community-wide one. So for the past few years, she's been reporting on a small town in the Midwest that illustrates that health issue: Sikeston, Missouri. Today on the show, Cara walks host [Emily Kwong] (https://www.npr.org/people/767284140/emily-kwong) through Sikeston's history — and what locals and medical experts have to say about how that history continues to shape the present.

What's A Weather Forecast Worth?

The federal government has been tracking the weather for more than 150 years. Yet over the last few decades, the rise of the Internet and big tech have made weather forecasting a more crowded space. Today, our colleagues at NPR's daily economics podcast [The Indicator] (https://www.npr.org/podcasts/510325/the-indicator-from-planet-money) report on the value of an accurate forecast and the debate over who should control weather data.

Conan The Bacterium's Superpower: Resisting Radiation

In the 1950s, scientists exposed a tin of meat to a dose of radiation that they expected would kill all forms of life. But one organism defied the odds and lived: Conan The Bacterium. Turns out this microorganism, known to science as Deinococcus radiodurans, is capable of surviving extreme levels of radiation — thousands of times the amount that would kill a human. So what's Conan's secret?Want more stories about the microbial world?

In The Club, We All ... Archaea?

Thor. Loki. Heimdall. They're not just Norse gods or Marvel characters. They're also the names of various Asgard archaea. These microscopic organisms are found all over the world, from marine sediment to mud volcanoes to hydrothermal vents. A growing body of research suggests we owe them an evolutionary debt. This episode, Emily and guest host Jon Hamilton explore the wild world of archaea: Where are they from? What do they do? And what can they tell us about the origins of life on earth?

Grape Growers' Next Collaborators? Robots

If you crossed WALL-E with a floor lamp, it might look a little like the PhytoPatholoBot. These robots aren't roving through space or decorating a living room — they're monitoring the stems, leaves and fruit of Cornell AgriTech's vineyards, rolling down each row and scanning for mildew.In this episode, host Emily Kwong and producer Hannah Chinn take a trip to Cornell to check out these new robots. How do they work? How effective are they? And what do local grape farmers – and neighbors – think about them? Interested in more robotics stories?

Who Does Science? Under Trump, That Could Change

The next four years may be challenging for foreign-born scientists who want to work in the United States. Foreign-born workers account for about half of the doctoral-level scientists and engineers working in the U.S., but the incoming Trump administration wants to make it harder for them to get H-1B visas. Some scientists worry a scarcity of H-1B visas may prompt top foreign researchers to work in other countries.

The Comeback Of The Southwest Peach

Centuries ago, Southwest tribal nations tended vast orchards of peach trees. But in 1863, thousands of those trees were cut down by the United States government when it ordered the Diné to leave their land as part of the Long Walk. Horticulturalist Reagan Wtysalucy wants to bring that those Southwest peaches back. Want to hear more Indigenous science?

The Ambitious Quest To Genetically Map All Known Vertebrates

The Vertebrate Genomes Project: It's an ambitious effort by an international group of scientists to create a "Genome Ark" by sequencing the genomes of about 70,000 animal species. The hope is that through all of this gene sequencing, scientists will be able to answer some basic but important questions like: What makes a bird, well, a bird? What makes a mammal a mammal? Plus, with so many species on the verge of extinction, can scientists record their genetic information before they go extinct – or better yet, maybe help save the population from going extinct? Guest host [ Jon Hamilton] (https://www.npr.org/people/2100615/jon-hamilton) , one of our favorite science correspondents, talks to [Erich Jarvis] (https://www.rockefeller.edu/our-scientists/heads-of-laboratories/1159-erich-d-jarvis/) , the chair of this project, to learn what this ark of animal genomes could mean for our future – and why a platypus qualified for early boarding.
