Amazon wants to kill the supermarket checkout line. The online retailing giant is opening its first cashier-less supermarket, where shoppers can grab milk or eggs and walk out without waiting in line or ever opening their wallets. It's the latest sign that Amazon is serious about shaking up the 0 billion grocery industry. Following the opening of several smaller convenience-type stores using an app and cashier-less technology to tally shoppers' selections, the store will be the first Amazon Go full-sized cashier-less grocery store. At the new store, which opened Tuesday in Amazon's Seattle hometown, shoppers scan a smartphone app to enter the store. Cameras and sensors track what's taken off shelves. Reusable shopping bags are displayed inside the Amazon Go Grocery store set to open soon in Seattle's Capitol Hill neighborhood. Items are charged to an Amazon account after leaving. 908

A tetraplegic man has been able to move all four of his paralyzed limbs by using a brain-controlled robotic suit, researchers have said.The 28-year-old man from Lyon, France, known as Thibault, was paralyzed from the shoulders down after falling 40 feet from a balcony, severing his spinal cord, the AFP news agency reported.He had some movement in his biceps and left wrist, and was able to operate a wheelchair using a joystick with his left arm.Researchers from the University of Grenoble in France, biomedical research center Clinatec and the CEA research center implanted recording devices on either side of Thibault's head, between the brain and skin, to span the sensorimotor cortex -- the area of the brain that controls motor function and sensation.Electrode grids collected the man's brain signals and transmitted them to a decoding algorithm, which translated the signals into movements and commanded a robotic exoskeleton to complete them.Over a period of two years, Thibault trained the algorithm to understand his thoughts by controlling an avatar -- a virtual character -- within a video game, making it walk and touch 2D and 3D objects.He trained on simple virtual simulations before using the exoskeleton -- which is assisted by a ceiling-mounted harness -- to eventually walk, and reach for targets with his arms.Over the course of the study, Thibault covered a total of 145 meters (around 476 feet) with 480 steps using the avatar, video and exoskeleton combined, researchers said in the study, which was published in 1549
