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…

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…

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…

The Cray-1 supercomputer, the world’s fastest back in the 1970s, does not look like a supercomputer. It looks like a mod version of that carnival ride The Round Up, the one where you stand, strapped in, as it dizzies you up. It’s surrounded by a padded bench that conceals its power supplies, like a cake…

If you didn't know it before the Cambridge Analytica debacle, you do now: Your digital habits are dual-use data. One company might analyze them to recommend you TV shows, while another might try to leverage them to influence an election. The first scenario you might be OK with, the other not so much. So, knowing…

Which makes marijuana tricky for casual users, and potentially problematic for new users who want to use cannabis to treat ailments like pain. It's difficult to quantify just…

You could argue that the door handle has had a disproportionate influence on modern robotics. It was the humanoids of the Darpa Robotics Challenge, after all, that were tasked with opening doors, and it was those machines that helped drive robots to where they are now. Today Boston Dynamics posted a video of its SpotMini…

We are living in the midst of a profound technological restructuring of human society. The machines that once only frolicked in science fiction have begun to infiltrate our lives. If you don't already work alongside a robot, you may in the near future. Self-driving cars promise to transform our roads, and the first truly sophisticated…

Click:1.5 ATA Hyperbaric Chamber Forget ruby-encrusted swords or diamond-tipped chainsaws. The scanning probe microscope is, quite literally, the sharpest object ever made. Hidden under its bulky silver exterior is a thin metal wire, as fine as a human hair. And at one end, its point tapers to the width of a single atom. Scientists wield…
