Magnetic slime 'robot' could help recover swallowed objects
 

Soft robots may soon be more flexible than ever... and a tad creepy. As The Guardianreports, researchers have developed a magnetic slime "robot" that can shift into different shapes to grab objects. It can encircle a group of pellets, for instance, and even stretch out in multiple directions to grab items on opposite sides. It's self-healing, too. The result might induce some nightmares for the squeamish and is more than a little reminiscent of Spider-Man's symbiotic Venom, but it's surprisingly effective.
