When American figure skater Nathan Chen performs at this year's Winter Olympics, he'll be looking to make history. The first and only skater in the world competing with five different types of quadruple jump—the salchow, loop, toe loop, flip, and lutz—he is poised to become the first athlete in the sport's history to execute these […]
After months of launch delays, the clandestine spacecraft built by Northrop Grumman finally launched on Sunday evening on board a SpaceX Falcon 9 rocket. The mission, code-named Zuma, lifted off from Cape Canaveral at 8:00 PM Eastern, headed toward an unknown destination in low Earth orbit. But it may not have made it there. On […]
For applied scientists—that intrepid cadre who get their hands dirty in the sometimes dangerous world beyond the ivory tower, participating in difficult decisions with little time and major consequences—getting the right answer is only half the battle. The other half is successfully explaining what they’ve found, and what it means. This winter’s debris flows in […]
This story originally appeared on Grist and is part of the Climate Desk collaboration. Beth Brunton’s magenta umbrella shields her from the weather on an April afternoon in Seattle. It’s a curious sight, because today is the first day in months without a drop of rain. It’s 75 degrees, and there’s not a cloud in the sky. “It gets […]

Now for a detailed explanation! How does a magnetic compass work? So, the Earth is like a giant magnet, just like that bar magnet that picks […]
If nature knows what it’s doing, it sure does a good job hiding it. Like, why would evolution produce an elephant with a shovel for a face? Or a shark with a cookiecutter mouth? Or an insect with a hollow peanut head? For very good reasons, as it turns out. Natural selection is an astoundingly […]

Having the sense to take a shortcut, the most direct route from point A to point B, doesn’t sound like a very impressive test of intelligence. Yet according to a new report appearing last week in Nature, in which researchers describe the performance of their new navigational artificial intelligence, the system’s ability to explore complex […]
Biotech has been betting big on Crispr, the gene-editing technique that promises to snip away some of humanity’s worst diseases. But last May, a small case study suggested the much-hyped technology might actually be quite dangerous—and pop went the Crispr bubble, briefly tanking shares of Crispr companies like Editas Medicine, Intellia Therapeutics, and Crispr Therapeutics.
