First, tardigrades on the moon, feral hogs on Earth, and more news from this week’s News Roundup.Scientists and students navigated the Northwest Passage waterways to study how the Arctic summers have changed. Last year, one day into expedition, the boat ran aground and cut the mission off before it could get started. This year, the team successfully launched from Thule, Greenland and completed their three-week cruise. Birds don’t just see the world from higher up than the rest of us; they also see

Sunscreen has been on the shelves of drugstores since the mid-1940s. And while new kinds of sunscreens have come out, some of the active ingredients in them have yet to be determined as safe and effective. A recent study conducted by the FDA showed that the active ingredients of four commercially available sunscreens were absorbed into the bloodstream—even days after a person stops using it.

Mauna Kea is the tallest mountain in Hawaii, towering over the Pacific at nearly 14,000 feet. That high altitude, combined with the mountain’s dry, still air and its extreme darkness at night, make it an ideal place for astronomy. There are already 13 observatories on the summit plateau. Now, astronomers want to build another, called the Thirty Meter Telescope, or TMT, which would become the largest visible-light telescope on the mountain. But many native Hawaiians don’t want it there, for a

Have you ever tried to make your favorite rocky road flavored ice cream at home, but your chocolate ice cream turns out a little crunchier than you hoped? And your ribbons of marshmallow are more like frozen, sugary shards? Chemist Matt Hartings and ice cream maker Ben Van Leeuwen, co-founder of Van Leeuwen Artisan Ice Cream in New York City, talk about the science behind how milk, sugar, and eggs turn into your favorite frozen desserts.

The Science Friday Book Club is buckling down to read Jennifer Ackerman’s The Genius of Birds this summer. Meanwhile, it’s vacation season, and we want you to go out and appreciate some birds in the wild. But for beginning birders, it may seem intimidating to find and identify feathered friends both near and far from home. Audubon experts Martha Harbison and Purbita Saha join guest host Molly Webster to share some advice. They explain how to identify birds by sight and by ear, some guides that can

Our Lunar Muse Most of us remember that iconic photograph of the Apollo 11 moon landing: Buzz Aldrin standing on a footprint-covered moon, one arm bent, and Neil Armstrong in his helmet’s reflection taking the picture. But there’s a much longer, ancient history of trying to visually capture the moon that came before the 1969 photo—from Bronze Age disks with crescent moons to Galileo’s telescope drawings to 19th-century photos and modern photographs. For millennia, we’ve been obsessed with the

Celebrating Apollo's 'Giant Leap' July 20, 1969 was a day that changed us forever—the first time humans left footprints on another world. In this segment, Ira Flatow and space historian Andy Chaikin celebrate that history and examine the legacy of the Apollo program. Apollo ushered in a new age of scientific discovery, with lunar samples that unlocked the history of how the moon and the solar system formed. It accelerated the development of new technologies, like the integrated circuit. And most of

If you’ve ever tried brewing your own beer or raising your own sourdough, then you know that the process of fermentation isn't easy to get right. How do you control the growth of mold, yeast, or bacteria such that it creates a savory and delicious new flavor, and not a putrid mess on your kitchen counter? David Zilber is Director of Fermentation at the restaurant Noma, and he tells his fermentation secrets. The human scent is made up of a combination of 100 odor compounds. Other mammals such as

A quarter of the world’s greenhouse gas emissions come from putting food on the table. From the fossil fuels used to produce fertilizers, to the methane burps of cows, to the jet fuel used to deliver your fresh asparagus, eating is one of the most planet-warming things we do. In our latest chapter of Degrees of Change, we're looking at how to eat smarter in a warming world.

Much has been written about the Manhattan Project, the American-led project to develop the atomic bomb. Less well known is Nazi Germany’s “Uranium Club”—a similar project started a full two years before the Manhattan Project. The Nazis had some of the greatest chemists and physicists in the world on their side, including Werner Heisenberg, and the Allies were terrified that the Nazis would beat them to the bomb—meaning the Allies were willing to try anything from espionage to assassination to

These days, a scientific paternity test is easily acquired, and its results are seen as almost indisputable. But what about the days before so-called foolproof DNA analysis? For most of human history, people considered the identity of a child’s father to be more or less “unknowable.” Then in the 20th century, when a flurry of events sparked the idea that science could help clarify the question of fatherhood, and an era of “modern paternity” was born. The new science of paternity, which includes

The eight-day squid-and-kin appreciation extravaganza of Cephalopod Week is nearly over, but there’s still plenty to learn and love about these tentacled “aliens” of the deep. After a rare video sighting of a giant squid—the first in North American waters—last week, NOAA zoologist Mike Vecchione talks about his role identifying the squid from a mere 25 seconds of video, and why ocean exploration is the best way to learn about the behavior and ecology of deep-sea cephalopods.

The official U.S. time is kept on a cesium fountain clock named NIST-F1, located in Boulder, Colorado. On a recent trip to Boulder, Ira took a trip to see the clock. He spoke with Elizabeth Donley, acting head of the Time and Frequency Division at the National Institute of Standards and Technology, about keeping the official U.S. time on track—and how NIST is using advanced physics to develop ever more precise and stable ways to measure time.

When wildfires rage in the West, Colorado State University atmospheric scientist Emily Fischer hops into a plane, and flies straight into the smoke. The plane is a flying chemistry lab, studded with instruments, and Fischer’s goal is to uncover the chemical reactions happening in smoke plumes, to determine how wildfire smoke may affect ecosystems and human health.

We’ve known for more than 200 years that cities are hotter than surrounding rural areas. All that concrete and brick soaks up the sun’s rays, then re-emits them as heat long after night has fallen. On top of that, waste heat from the energy we use to power our buildings, vehicle emissions, and even air conditioning units can cause some cities to be as many as 20 degrees Fahrenheit warmer than their rural surroundings—creating “urban heat islands.” Between the toll that heat takes on the body and the

The “spooky physics” of the quantum world has long been marked by two key ideas: The idea of superposition, meaning that a quantum particle can exist in multiple states simultaneously, and the idea of randomness, meaning that it’s impossible to predict when certain quantum transitions will take place. Writing in the journal Nature, Zlatko Minev and colleagues report that they may be able to make the quantum behavior slightly less mysterious. Minev joins Ira to talk about the finding, and what new
