Y'all, it's the most wonderful time of the year: Fat Bear Week! Brown bears in Katmai National Park and Preserve are putting on the pounds before they hibernate. During this time, their metabolism, heart and breathing rate slow way down and they recycle their waste internally. Today, we look at the cool (and peculiar) biological processes taking place during hibernation. Plus, we talk through some other science headlines we're obsessing over, including the light pollution from satellites and how gravity affects antimatter.Read a science headline you want to know more about?

Here on Short Wave, we're getting into the Halloween spirit a little early with a look at the world's oldest mummies. They're found in modern-day northern Chile. The mummies are well-preserved, so over the past 7,000 years, some have been exhumed for scientific study. But recently, something startling happened: Some of the mummies started to decompose. Today on the show, Regina G. Barber talks to archeologist Marcela Sepulveda about the civilization that made these mummies: the Chinchorro people. We dig into the science behind their mummification techniques and how the changing planet is affecting archeologists' ability to study the past. Fascinated by a science mystery?

A new robot is designed to sink sargassum before the stinky seaweed comes ashore. Blooms of sargassum, a leafy brown seaweed, have increased in size and number over the past decade. As the blooms have grown, so too has their impact on coastal communities. The stinky seaweed can wreck local economies and ecosystems — and even threaten human health, some research suggests. But the creators of the AlgaRay say that their robot might do more than halt this damage. It could also fight climate change.This week NPR is doing something new — dedicating an entire week to stories and conversations about the search for climate solutions.

A tiny worm that regenerates entire organs. A South American snail that can regrow its eyes. A killifish that suspends animation in dry weather and reanimates in water. These are the organisms at the heart of regeneration science. But exactly how they do these things is still a mystery to scientists. Today on the show, Regina G. Barber talks to microbiologist Alejandro Sánchez Alvarado about this mystery. They get into what regeneration looks like, why humans can't do it (yet) and where the science may lead us in the decades to come.

The last several decades have taken a toll on the oceans: Some fish populations are collapsing, plastic is an increasing problem and climate change is leading to coral bleaching — as well as a host of other problems. But marine biologist and World Economic Forum programme lead Alfredo Giron says there's room to hope for the seas. He works to create systems that governments and the fishing industry can use to make sure fishing is legal and sustainable so oceans thrive for years to come. In this encore episode, he talks to host Aaron Scott about his work and how managing the ocean is a lot about managing people.We spoke to Alfredo Giron about his research and thoughts, the episode is not meant to reflect the World Economic Forum's positions.Have questions about the world around you?

We're entering a new era of astrophysics. The James Webb Space Telescope is helping scientists test existing ideas and models of how the universe was created—on a whole new level. This telescope is sending back images of galaxies forming under a billion years after the Big Bang—way earlier than astronomers had previously expected. Not only that, scientists had anticipated that later—but still very early—galaxies would be small, barely formed blobs; instead, the galaxies in these images have spiral arms. So, today's show is all about GALACTIC CONTROVERSY! Computational astrophysicist Jorge Moreno talks with fellow astronomer and Short Wave's Scientist in Residence Regina G. Barber about how these new findings are stirring up controversy in the scientific community and the lessons we can learn from galaxies. Questions or controversies? Email us at [email protected].

This week, the Food and Drug Administration approved new COVID vaccines this week. It comes at a time when COVID cases, hospitalizations and deaths are on the rise. It's also the first time that the federal government is not paying for the vaccines. Given this confluence of events, we huddled with our colleagues, intrepid health correspondents Maria Godoy and Rob Stein. They gave us the lowdown on the CDC's recommendations for who should get it, how protective the booster is, how to access it regardless of your insurance status—and even how time this booster with other vaccines that may be on your radar.Check out Rob and Maria's full COVID booster Q&A here.

40 million miles of road unite us. They also cause mass destruction for many species. Today, environmental journalist Ben Goldfarb and host Aaron Scott go on a tour of that destruction — the subject of Ben's new book Crossings: How Road Ecology Is Shaping the Future of Our Planet. But don't worry, it's not all grim! Along the way, we learn why fewer insects are hitting our windshields, talk about the breakthrough that is highway overpasses, and how at least one bird has adapted to avoid 18-wheel semi-trucks.

More than 5,000 square miles of central California coast could soon become the newest national marine sanctuary in the United States. It could also make history as one of the first federal sanctuaries to be initiated by a Native American tribe—the Chumash—and become part of a growing movement to give tribes a say over the lands and waters that were once theirs. NPR climate reporter Lauren Sommer dives into the details with host Regina G. Barber, touching on ocean science, heritage and what's in a name.

Have frequent, burning pee? Cramping or the urge to pee even though you just went? If you haven't yet, you probably will eventually—along with an estimated 60% of women and 10% of men. That's the large slice of the population that experiences a urinary tract infections (UTI) at least once. Many people avoid talking about these infections, but about one in four women experience recurring UTIs. No matter what they do, the infections come back, again and again. So today on the show, Regina G. Barber takes producer Rachel Carlson on a tour of the urinary tract. We zoom into what recurring UTIs may have to do with changes on the DNA of our bladder cells and the hidden bacterial houses in our bladder walls.

This year, the hottest July ever was recorded — and parts of the country were hit with heat waves that lasted for weeks. Heat is becoming increasingly lethal as climate change causes more extreme heat. So in today's encore episode, we're exploring heat. NPR climate correspondent Lauren Sommer talks with Short Wave host Regina G. Barber about how the human body copes with extended extreme heat and how today's heat warning systems could better protect the public.

Food allergies have risen in the United States over the last few decades. Research suggests that 40 years ago the actual prevalence of food allergies was less than 1%. But this year, the Centers for Disease Control and Prevention (CDC) released data showing that almost 6% of U.S. adults and children have a food allergy. But this trend is not present in all countries — and what people are allergic to varies globally. Today, we dive into the complex world of food allergies with Dr. Waheeda Samady.

Smallpox is a deadly virus. At one point, it killed almost 1 in 3 people who had it. Almost 300 million of those deaths were in the 20th century alone. It was extremely painful, highly contagious and many people thought it would be impossible to wipe out—until it was. On May 8, 1980. the 33rd World Health Assembly declared the world free of smallpox. This marked the first—and only—time a human disease was eradicated globally. Epidemiologist and host of the podcast Epidemic: Eradicating Smallpox Céline Gounder has been looking into this history. Today, she shares the intense journey to eradicate smallpox in Bangladesh (spoiler alert: there are literal speedboats) and reflects on what this history tells us about the importance of healthcare that meets the needs of individuals and communities today.

Workers in Japan started releasing treated radioactive water from the Fukushima Daiichi nuclear power plant into the Pacific Ocean on Thursday. Reactors at the plant began melting down after a 2011 earthquake and tsunami that hit the area. To stop the meltdown, plant workers flooded the reactors with water. But even now, when the plant is offline, the reactors need to be cooled. All that water—about 350 million gallons—is being stored on-site in over 1,000 tanks. And now, these tanks are almost full. Today on the show, host Regina G. Barber talks to NPR reporters Geoff Brumfiel and Kat Lonsdorf about the official plan for the radioactive wastewater, the science behind the release and why some are unhappy about it.

It's no secret that our electric grid is a flaming hot mess — and in order to reduce emissions, the U.S. needs to get a lot more renewables onto the grid. But there's a problem: Our electric grid is too old and outdated to handle this new technology. In fact, many of the copper wires on transmission lines are using technology from as far back as the early 1900s! Because of this, thousands of wind and solar projects are waiting for years to get online. The Inflation Reduction Act is incentivizing a big transition to things like electric cars, heat pumps and other devices, which means we'll need even more electricity that will further push the limits of existing infrastructure. Now more than ever, we need this new power. With this in mind, some tech companies are finding solutions to make the existing grid work better. Aaron Scott talks with NPR's climate solutions reporter Julia Simon about these solutions and how they might be a whole lot quicker — and cheaper — than you'd think.

For people with endometriosis—a mysterious disease where endometrial tissue grows outside of the uterus—medical visits can be especially frustrating. It takes some patients years (on average, ten years) to get a diagnosis and treatment options are limited. There are currently no cures. One researcher, Dr. Kate Lawrenson, is trying to change that. She and her team of researchers have created a cellular atlas of the disease and hope this cell-by-cell approach will open up doors for faster diagnosis options and better ways of managing it. In the meantime, she hopes that more people will learn about the disease in the first place.Want us to break down the science underpinning your health?

Trash from humans is constantly spilling into the ocean — so much so that there are five gigantic garbage patches in the seas. They hang out at the nexus of the world's ocean currents, changing shape with the waves. The largest is the Great Pacific Garbage Patch. These areas were long thought to have been uninhabited, the plastics and fishing gear too harmful to marine life. But researchers have recently uncovered a whole ecosystem of life in this largest collection of trash. Today, with the help of marine biologist Fiona Chong, we meet the tiny marine life that calls this place home.Read Fiona and her collaborators' paper, High concentrations of floating neustonic life in the plastic-rich North Pacific Garbage PatchInterested in hearing other tales of marine life?
