Solar Panels Power New Schools—and New Ways of Learning
Dressed in pastel pink and green for an early spring day, second-grader Katherine Cribbs was learning about energy on a virtual field trip—to her own school. With a flurry of touch-screen taps, she explored the “energy dashboard” of Discovery Elementary in Arlington, Virginia. On her tablet, she swiped through 360-degree views of her school, inside…
Apparently We Can Let the Stock Market Fight Climate Change
Fixing the effects of climate change on Earth isn’t complicated. When you get down to it, all we humans need to save the world is ingenuity, grit, cooperation, and $53 trillion. Where is humanity supposed to come up with that kind of cash at this time of night? The International Energy Agency says Earth needs…
Mini Brains Just Got Creepier—They’re Growing Their Own Veins
The first human brain balls—aka cortical spheroids, aka neural organoids—agglomerated into existence just a few short years ago. In the beginning, they were almost comically crude: just stem cells, chemically coerced into proto-neurons and then swirled into blobs in a salty-sweet bath. But still, they were useful for studying some of the most dramatic brain…
All the Places Tiangong-1 Won’t Land (and Where It Still Might)
No one knows exactly when or where China's abandoned Tiangong-1 space station will return to Earth. But the map on Ted Muelhaupt's computer gives him a better idea than most. "I'm looking at it right now, and it's telling me the vehicle's not gonna land in Quito," he says. The date is Thursday, March 29,…
A Giant Iceberg Grounded Itself Near a Greenland Town
When an iceberg breaks off from a glacier, it can drift for thousands of miles, traveling freely across the open ocean. But last week, an iceberg’s journey was interrupted when it got stuck on a shallow part of the seafloor along Greenland’s western coast. In other words, the iceberg was grounded—and it had lodged itself…
The Physics of Drafting in the Tour de France
Power is the most important thing in road bicycle racing like the Tour de France. If you want to move along on a bike at a constant speed, you have to use energy. There are no free rides. But there is one thing that can make a big difference in a rider's energy use—and that's…
Physics Explains Why No One Can Beat the Freeze
The only thing I know about the Freeze is that no one can beat the Freeze (except with a generous head start). And he's awesome. In case you haven't seen, the Freeze is this guy in a turquoise spandex suit that challenges mere mortals to a race in the outfield of the Atlanta Braves SunTrust…
These Conservationists Are Desperate to Defrost Snake Sperm
It’s hard to pick which species to save in Brazil right now. Yellow fever is tearing through primate populations, wiping out squirrel and howler monkeys. Poachers are nabbing giant anteaters for meat and blue macaws to sell as exotic pets. But conservation biologist Rogério Zacariotti wants to save a venomous yellow viper—the golden lancehead. But…
How the Government Controls Sensitive Satellite Data
During the Cold War, on the vast, barren flatland around Area 51's dried-up Groom Lake, the military developed a stealth spy plane code-named Project Oxcart. Project personnel were sworn to secrecy, but still, US officials worried that the Soviets would find out what they were up to. With good reason: Up above, USSR satellites were…
Climate Change Is Coming for Underwater Archaeological Sites
This story originally appeared on Atlas Obscura and is part of the Climate Desk collaboration. On a choppy voyage to Antarctica in 1928, the crew of the ship that would eventually be rechristened as the Vamar bestowed upon their vessel an optimistic nickname: “Evermore Rolling.” It proved to be a bit of a misnomer. Far…
