A shape-shifting drone suggests the future of rescue missions

-

A new kind of drone has been designed to fold up its arms and squeeze into tight spots, potentially to scout around on rescue missions. Researchers from the University of Zurich developed a drone with four arms that can retract while flying to fit into gaps and holes. The goal is to send drones where humans can’t go and make it easier to locate victims in a collapsed building in the event of an earthquake or fire.

To some extent, these types of rescue drones already exist, but they are sometimes too large and oblong-shaped to fit into most openings, like a crack in the wall or through fallen bars. The researchers say their new drone’s shape-shifting abilities were inspired by the movement of birds. When faced with a narrow entrance, it…

In a world first, China lands a spacecraft gently on the Moon’s far side

This evening, China became the first nation to land a spacecraft gently on the far side of the Moon, according to China Global Television Network America . A Chinese robotic lander and rover, which launched from China in early December, descended into a crater on the side of the Moon that’s always facing away from Earth. The touchdown marks a significant technological feat for the country, and puts China in an elite category of spaceflight achievement all its own. The landing is part of China’s Chang’e-4 mission — one of a series of planned missions to explore the lunar surface. Prior to this program, China sent a lander and a rover to the Moon, making it the third country to ever softly land on the lunar surface. That lander, part of the...

Must-play Nintendo Switch games are almost half off

Photo by Amelia Holowaty Krales / The Verge Nintendo finally announced the Switch with an OLED screen that comes out in October, but right now, GameStop is hosting a big one-day discount on two must-have Switch games: Super Mario Odyssey and Fire Emblem: Three Houses . Each game is going for $35 (usually $60) for the physical or digital versions, and if you have the means, I suggest getting both. Super Mario Odyssey is the latest (delightful) installment in the long-running Mario 3D platforming franchise, while Fire Emblem: Three Houses has strategic, turn-based battles interspersed with team- and friend-building elements you’d usually find in a Persona game. If you’re looking for more Switch games, Best Buy has a selection of discounted titles (physical, not digital) that cost...

Image: G4 TV After more than a year of teasing and occasional streams, G4 will make its return as a linear TV channel on November 16th . So far, the channel is confirmed to appear on Comcast/Xfinity, Verizon Fios, Cox, and Philo. Since announcing its return last year, G4 has put out some reunion content plus occasional streams on Twitch , where the network will maintain a “multi-year promotional and commercial partnership.” Though the original G4 faded out when it got rebranded as the Esquire Channel about eight years ago, the network’s new mantra is that “we never stopped playing.” Network president Russell Arons writes in a statement that G4 “can’t wait to have our fans join us in our hilarious and fairly preposterous sandbox.” When G4 comes back...
