Pilgrim Nuclear Power Plant To Say Goodbye To Its Radioactive Waste Just before Thanksgiving, the Pilgrim Nuclear Power Plant in Plymouth is expected to reach a historic milestone. All the radioactive fuel that generated electricity—and controversy—for nearly half a century will finally be removed from the reactor building. It will be stored outside in special steel and cement casks. The rare occasion will be celebrated by both supporters and opponents of the plant. But as the decommissioning of...

Ice-Hunting Lunar Rover Robot Gets A Landing Site This week, NASA announced that it had selected a destination for a planned robotic lunar rover called VIPER, the Volatiles Investigating Polar Exploration Rover. The mission is planned for launch in 2023, and will rove about the Moon’s south pole, mapping the location and concentration of water ice deposits. The plan is for a commercial spaceflight mission to deliver the rover to a spot near the western edge of the Nobile Crater at the Moon’s sou...

Nighttime Streetlights Are Stressing Out Urban Insects As insect populations—including bees, moths, and other pollinators—decline worldwide, researchers have established a variety of potential causes, including climate change, pesticides, and habitat loss. But now, new findings suggest yet another culprit may be part of the equation: night-time lighting, like street lights in populated areas . A team of entomologists in the United Kingdom looked at populations of moth caterpillars under street l...

Scientists Potty Train Cows To Lower Greenhouse Gasses Scientists have known it for a long time: Cattle are a major source of nitrogen emissions, contributing to the global warming crisis. Alternatives have been tossed around for years: from eating less meat to feeding cows seaweed. Now, a new study out of Germany and New Zealand has a more outside-the-box solution: potty-training calves. Scientists trained cows to pee in just one spot—dubbed the “MooLoo”— so their urine can be cleaned before it...

New Policies Emerge In The Wake Of Climate-Connected Disasters This week, people across the United States continued to be reminded of the results of a shifting climate—with people in the Gulf states still recovering from Ida, northeastern states dealing with the aftermath of Hurricane Ida-induced flooding, and western states battling wildfires and smoke. With climate-related disasters as a backdrop, President Biden announced a goal of shifting some 45% of U.S. energy production to solar power by...

To Breed An Oyster In the ocean, climate change involves more than just warming temperatures. Water levels are shifting, and ocean chemistry is changing. Changes to ocean salinity caused by shifting amounts of freshwater could have big effects on the health of oysters, who need a certain range of saltiness in the water to be happy. As part of her doctoral work at Louisiana State University, researcher Joanna Griffiths bred hundreds of families of oysters, looking for clues to what makes an oyste...

Fact Check My Feed: Why Are People Taking Discredited Horse Medicine For COVID-19? If you’ve been online at all in the past few weeks, you’ve probably seen discussion about the drug ivermectin. It was originally developed as an antiparasitic treatment for livestock, and in 2015, the Nobel Prize in Medicine went to scientists who found that it helped control parasitic diseases in humans as well. But recently, non-medical groups have been incorrectly promoting the drug as a treatment for COVID-19—...

Nation Grapples With Several Climate Disasters At Once Hurricane Ida wreaked havoc on the eastern U.S. this week. It all started in Louisiana, leaving daunting damage and a long road to recovery for residents . Even though Ida was downgraded to a tropical storm after leaving the state, it left a trail of destruction through the eastern U.S. and mid-Atlantic , flooding cities and damaging homes. In the New York area, at least a dozen people died after the region was pummeled by more than half a f...

A Skeletal Record Of Medieval England Society Whether you like it or not, a record of your life is constantly being chronicled. No, not through the internet or on social media—through your bones. If you’ve ever fractured a bone, that skeletal trauma stays with you forever, even after it heals. So researchers across the pond are using bones from medieval times to put together a picture of what life was like. The bones in the study came from ordinary people in medieval Cambridge in the United King...

Pfizer’s Vaccine Is Now Fully Approved. What’s Next For The Pandemic? This week, the COVID-19 vaccine marketed by Pfizer finally received full FDA approval, moving out of the realm of “emergency use” to the status of a regular drug . In the wake of that change, many organizations—from the Pentagon to Ohio State University to the city of Chicago—are moving to require vaccinations against the coronavirus. It remains to be seen just how much the status change will move the needle on vaccination num...

You, Too, Can Be All Thumbs. Or At Least Three. Take a look at your hand and fingers—and imagine that instead of five digits, you had an additional thumb, approximately opposite your natural thumb. Researchers at University College London built what they call the “Third Thumb”—a flexible, 3D-printed prosthetic device, controlled by pressure on sensors under the wearer’s big toes.The researchers studied how people wearing the thumb adapted their mental models of the world to incorporate their new...

A Stomp, A Roar, An Elephantquake? An adult African elephant, the largest land animal on Earth, can weigh as much as two tons. Their activities—walking, playing, even bellowing—might shake the ground beneath them. But research in the journal Current Biology finds that the signals from an elephant’s walk are capable of traveling as far as three kilometers, while a roaring bull, or male elephant, might be detectable a full six kilometers away with just seismological monitoring tools. Biologist Bet...

This Fish Is The Master Of The Poignant Pause When listening to a well-practiced speaker, like during a lecture, a political event or during a favorite public radio show, you may notice they use pauses for dramatic effect. This type of nuance in communication may seem distinctly human, but we’re not the only species that takes advantage of pauses in speech to make a point. Enter the electric fish: It discharges electric pulses nearly constantly, which tells other fish basic identifying informati...

Writing, Like Geology, Requires A Little Digging When author John McPhee first considered the piece of writing that would become his 1998 book, Annals of the Former World , he envisioned a short, un-bylined article in The New Yorker, in which he would visit a road cut on Route 80—a piece that could probably be completed in a few days. Instead, that idea became a 700-page coast to coast exploration of the geology of North America, a project that took over 20 years to complete. In this archival in...
