Debris from satellites, rockets and other space infrastructure are crowding low-Earth orbit. Occasionally, that space junk crashes down to Earth. For Samantha Lawler, an associate professor of astronomy at the University of Regina in Saskatchewan, such debris was mostly a theoretical nuisance. Then a nearby farmer found remnants of a SpaceX craft on his land, and Lawler was pulled into the murky l...

The 2024 Summer Olympics in Paris came to a close on Sunday—and swimmers swam the Seine as promised. The two astronauts sent to the International Space Station on a Boeing Starliner craft in June are still in limbo, with no set return flight. The EPA is acting quickly to suspend sales of products that contain the pesticide dimethyl tetrachloroterephthalate over safety concerns. Plus, we discuss a...

The American Cancer Society published a study suggesting that for 8 or 34 cancers tracked, case rates are rising from one generation to the next. While headlines often point to sedentary lifestyles and higher weights as a possible cause, some experts say that these factors alone cannot explain the spike. In more hopeful oncology news, there’s a new blood test for colorectal cancer–though it doesn’...

Gazing up at the night sky is a universal human experience, likely as old as our species itself. But how did our ancient ancestors feel about what they saw in the heavens, and how did it shape their lives? In Episode Two of our three-part Fascination miniseries on unusual archaeology, science journalist Kata Karáth introduces us to archaeoastronomy—the study of how people in the past experienced a...

Sex testing has a long history in sports. As participation in events like the Olympics opened to women, organizers and audiences alike began questioning the sex of the athletes. The tests devised to “prove” an athlete’s sex have been invasive and inaccurate. Rose Eveleth, host of the NPR and CBC podcast Tested, brings us the story of sex testing and where the science stands. Listen to Tested: http...

It’s a scorching summer, with record-breaking temperatures last Monday. Rain really is harder to predict, and greenhouse gasses are probably to blame. Polio is circulating in Gaza’s wastewater and could spread as conflict leads to crowding, poor sanitation and missing routine vaccinations. Plus, we discuss a shocking price for a promising HIV vaccine, cocaine sharks and komodo dragons with iron-ti...

Fish trapping is an ancient practice, reaching across the globe from at least as far back as 11,000 years ago. It takes advantage of coastal tides and human-made chambers to catch and release fish. The simple but ingenious ancient fishing structures are built on two intertwining principles: the ocean can provide for us if we properly care for it. Archaeologists are mapping the possible locations o...

Meditation is mostly mainstream, with many people using mindfulness to manage stress. But dedicated practitioners of advanced meditation move beyond mindfulness into a state where consciousness “entirely falls away.” That’s according to today’s guest: Matthew Sacchet, an associate professor and director of the Meditation Research Program at Harvard Medical School and Massachusetts General Hospital...

President Biden is far from the only positive as COVID is experiencing a summer surge. Windows malfunction grounds planes and causes outages for banks, hospitals and emergency services. The Perseid meteor shower gives you plenty of shooting stars to see. Plus, we use the Twisters premiere as an excuse to talk about wild weather. Recommended reading COVID Rates Are Rising Again. Why Does It Spread...

The Seine is set to feature prominently in the Paris 2024 Olympics’ Opening Ceremony—and in its marathon swimming events. But this urban waterway has been challenging to clean and keep clean after a particularly wet summer and high bacterial counts. What can the Parisian organizers learn from the revitalization of a U.S. river that was so polluted that it inspired the creation of the Environmental...

Science journalist and Radiolab host Latif Nasser found himself at the center of a space mystery. A space poster in his child’s room showed Zoozve, a moon circling Venus. Only Nasser had never heard of Zoozve—and neither had anyone else. Nasser brings us the story of Zoozve the quasi-moon and brings listeners the opportunity to name a quasi-moon of their own. Recommended listening Zoozve  Name a Q...

We commemorate the 55th anniversary of the Apollo 11 mission, dive into NASA’s groundbreaking Mars habitat simulation and discuss the innovative ​​“stillsuits” designed to recycle astronaut pee and how they could enhance spacewalks. Plus, we discuss the record-breaking Hurricane Beryl and its implications for climate change policies, and a surprising case of the plague in Colorado.  Recommended re...

We’re at the end of the Nathaniel B. Palmer’s Antarctic expedition. The researchers onboard are returning sea ice and thousands of gallons of seawater. These samples will allow them to examine biogeochemical processes, some of which are linked to climate change. As the research vessel makes its way back to port, the scientists reflect on the future of our planet and the question of whether the ice...

Przewalski’s horses are truly wild horses, even the ones held in captivity. They traditionally roamed the Central Asian steppes, so you can imagine everyone’s surprise when two separate accounts on TikTok claimed to have found a Przewalski’s horse here in the U.S. But as guest and Scientific American associate news editor Allison Parshall will tell you, the real story is the remarkable conservatio...

We’re looking at our reporting—from 100 years ago. In 1924 Scientific American’s pages were bemoaning traffic, waste management and pests. They were also praising the by-products of coal tar and those substances’ use in household items. While the record is clear on the toxicity of fossil fuels to our environment and our health, demand for fossil-fuel-based “petrochemical” products such as plastic...

The Supreme Court dismissed a case about Idaho’s abortion ban, preserving a lower court ruling that allows for emergency access to abortion in the state. NASA pushed back a return flight for two Starliner astronauts so that Boeing and the agency can better understand the helium leaks and thruster failures that plagued the spacecraft’s launch.  Infectious disease experts are still tracking the tran...
