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

A student gunman opened fire at a southern California high school Thursday morning, leaving two dead and several others injured, officials said.According to authorities, the male suspect, who is a student at the school, opened fire in the quad at Saugus High School in Santa Clarita around 7:38 a.m. before classes started. Authorities were on scene by 7:40 a.m. after receiving several 911 calls about the shooting. The suspected gunman shot and killed two students, a 16-year-old female a 14-year-old male, and injured three others before shooting himself in the head, police said. He is currently in custody and being treated at a local hospital, according to Los Angeles County Sheriff Alex Villanueva. Officials say he is in grave condition.Video obtained at the scene showed the suspect taking a .45-caliber semi-automatic pistol from a backpack before shooting the five other students and then himself, said Capt. Kent Wegener of the Los Angeles County Sheriff's Department.The other victims include two females, ages 14 and 15, and a 14-year-old male, police said. They were transported to local hospitals with gunshot wounds.Police are investigating the alleged shooter's home, which is near the school, authorities said at a press conference. Officials also said that Thursday was the student gunman's 16th birthday.The suspected shooter's mother and girlfriend are being interviewed by detectives. Other student witnesses are also still providing information to police.Other schools in the district were placed on lockdown amid the shooting. Police say they still don't have a motive in the shooting.EDITOR'S NOTE: A previous version of this story said that three people were killed based on a report from ABC News. ABC News is no longer reporting that three students have died, and this story has been updated to reflect ABC's reporting. 1862

Airlines are prohibited from banning specific breeds of dogs on board flights as service or emotional support animals, the US Transportation Department said Thursday, amid controversy over safety and passengers abusing the policies for emotional support animals.The guidelines outlined by department officials appear to invalidate a recently-announced Delta Air Lines policy barring "pit bull type dogs" from traveling as service or emotional support animals.Airlines are allowed a case-by-case determination of whether an animal is safe to travel, and airlines can also require people traveling with emotional support animals to check in at the airport lobby, rather than online, to allow an airline official to review the animal."The airline does have the authority to do an individualized assessment of any dog, every breed of dog, and if any dog -- no matter the breed -- is determined to pose, or deemed to pose a risk to the health or safety of other passengers, the airline is free to deny boarding," a department official, who spoke on the condition of anonymity, told reporters on a conference call explaining the change.The Transportation Department is developing new long-term rules for passengers with service animals.The department will not seek to invalidate any airline policies prohibiting animals other than dogs, cats and miniature horses -- the most common species of service animals -- from traveling as emotional support animals, the officials said.Airlines will have one month to change any policies that do not comply with the interpretation. They did not specify which policies or airlines they believe are not in compliance.The airline industry said it supports the DOT guidelines because of its concerns about passengers abusing the allowances for emotional support animals, or ESAs."The availability of fraudulent ESA credentials online has enabled people who are not truly in need of animal assistance to abuse the rules and evade airline policies regarding animals in the cabin," said Airlines for America, an industry group. "With over a million passengers bringing ESAs on flights last year, airlines and airports saw a sharp increase in incidents such as biting and mauling by untrained animals.In one of the more recent incidents, a flight attendant who was bit by an emotional support animal two weeks ago 2352

American hiring rebounded last month after an unusually weak job market in February, but signs still point to a gradual economic slowdown.The US economy added 196,000 jobs in March, up from 33,000 the prior month. Despite a slight upward revision from the original estimate, February hiring remained the weakest since September 2017.Meanwhile, the unemployment rate remained at 3.8%, a level near historic lows.While March hiring was robust, it brings the first-quarter average to 180,000 jobs created per month, down from 223,000 per month on average in 2018. Economists have been expecting a slowdown, and so far it looks gradual enough to support the idea that the economy may glide to a lower level of activity in 2019 735
