Rocky Mountain Spotted Fever is one of the deadliest tickborne diseases in the United States, often killing people within about a week if left untreated. At one point, the San Carlos Apache Reservation had rates of infection 150 times the national average. But now, they've achieved a huge milestone — no deaths from the disease in at least five years. NPR science correspondent Pien Huang and producer Megan Lim visited the reservation to see the program that led to their success.

The U.S. tested nuclear weapons until the early 1990s. Since then, scientists have been using supercomputers and experiments to simulate nuclear test detonations, without detonating any nukes. But there are signs the world's nuclear powers may be readying to test again: Russia, China and the U.S. are all upgrading their nuclear test sites.
NPR science correspondent Geoff Brumfiel was among a small group of journalists allowed to tour an underground laboratory where this research happens.

For people with two hands, one is usually dominant. On a molecular level, life takes this to the extreme. All of the DNA in earthly living things twists to the right, whereas the protein building blocks favor a kind of left-handed chemistry. But in recent years, scientists have worked toward a kind of mirror version of life. The technology to make mirror life likely won't exist for at least a decade. Still, a group of concerned scientists published a 299-page technical report calling for a stop to the science. New York Times science columnist Carl Zimmer explains how a mirror microbe could wreak havoc on life on Earth in the future.
Check out the full technical report and Carl's full article.

What do large crowds of people and water have in common? They both act like fluids. When crowds cheer, sway and clump together, the movements look like ripples of water. Researchers hope insights from physics like this one could help officials and engineers create safer crowds at festivals.

Black holes are notorious for gobbling up, well, everything. They're icons of destruction, ruthless voids, ambivalent abysses from which nothing can return — at least, according to pop culture. But black holes have another side: Astrophysicists have seen powerful jets, sometimes millions of light-years long, shooting out of supermassive black holes – including the one at the center of our own galaxy. So today, we're getting to know the other side of black holes, and the powerful role they may play in creating and shaping the cosmos.

Ecologist Gergana Daskalova moved back to the small Bulgarian town of her childhood. It's a place many people have abandoned — and that's the very reason she returned. At the same time as land is being cleared around the world to make room for agriculture, elsewhere farmland is being abandoned for nature to reclaim. But what happens when people let the land return to nature? This episode, science reporter Dan Charles explains why abandoned land has conservationists and researchers asking: If we love nature, do we tend it or set it free?

Farts are funny and sometimes smelly. But are they a legitimate topic of research?
More than 40% of people worldwide are estimated to suffer from some kind of functional gut disorder — from acid reflux, heartburn, indigestion, constipation and irritable bowel syndrome to inflammatory bowel disease. So, yes, freelance science writer Claire Ainsworth thinks so. Claire speaks with Emily about two teams of scientists studying intestinal gases, who she profiled in a recent New Scientist article — and why understanding people's gut microbiome through a fart-shaped window may help treat these conditions at the source.

Bird flu, or avian influenza, is spreading among livestock and other mammals in the United States, raising concerns that another pandemic may be looming. Last month, California declared a state of emergency due to rising cases in dairy cattle, and there have been over 65 human cases in the U.S. during this outbreak. While cases have been largely mild and risk to the public is still considered low, scientists warn it could evolve and become more dangerous.

Put on your headphones. In today's episode, host Emily Kwong leads us on a night hike in Patuxent River State Park in Maryland. Alongside a group of naturalists led by Serenella Linares, we'll meet a variety of species with unique survival quirks and wintertime adaptations. We'll search out lichen that change color under UV light and flip over a wet log to track a salamander keeping warm under wet leaves. Emily may even meet the bioluminescent mushrooms of her dreams. Plus, we talk about community events to get outside, such as the City Nature Challenge and Great American Campout.

Around the turn of the century, 3.8 million people banded together in a real-time search for aliens — with screensavers. It was a big moment in a century-long concerted search for extraterrestrial intelligence. So far, alien life hasn't been found. But for people like astronomer James Davenport, that doesn't mean the hunt is worthless — or should be given up.
No, according to James, the search is only getting more exciting as new technology opens up a whole new landscape of possibilities. So today on the show: The evolving hunt for alien life.

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.

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.

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.

In a previous version of this episode, we said that the research team used carbon-dated fossils to calibrate a molecular clock aimed at estimating the age of LUCA. In fact, the researchers used radio isotopic-dated fossils for that purpose.

When you picture a dinosaur, what does it look like? For Jingmai O'Connor, 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?

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.

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 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.
