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 subtle design feature of the AR-15 rifle has raised a technical legal question that is derailing cases against people who are charged with illegally buying and selling the gun’s parts or building the weapon.At issue is whether a key piece of one of America’s most popular firearms meets the definition of a gun that prosecutors have long relied on.For decades, the federal government has treated a mechanism called the lower receiver as the essential piece of the semiautomatic rifle, which has been used in some of the nation’s deadliest mass shootings. Prosecutors regularly bring charges based on that specific part.But some defense attorneys have recently argued that the part alone does not meet the definition in the law. Federal law enforcement officials, who have long been concerned about the discrepancy, are increasingly worried that it could hinder some criminal prosecutions and undermine firearms regulations nationwide.“Now the cat is out of the bag, so I think you’ll see more of this going on,” said Stephen Halbrook, an attorney who has written books on gun law and history. “Basically, the government has gotten away with this for a long time.”Cases involving lower receivers represent a small fraction of the thousands of federal gun charges filed each year. But the loophole has allowed some people accused of illegally selling or possessing the parts, including convicted felons, to escape prosecution. The issue also complicates efforts to address so-called ghost guns, which are largely untraceable because they are assembled from parts.Since 2016, at least five defendants have challenged the government and succeeded in getting some charges dropped, avoiding prison or seeing their cases dismissed entirely. Three judges have rejected the government’s interpretation of the law, despite dire warnings from prosecutors.Federal 1866

A Tulsa, Oklahoma, woman is urging brides to use more caution when selecting a wedding photographer than she did. "I was planning this since I was a little girl and it turned out just the way I wanted it and I have no pictures," Natalie Barney said. Barney was on a tight budget for her big day. "I just wanted a small wedding, but it had to be big enough for everyone to see my pink dress," Barney said.When she saw an advertisement for an "affordable" photographer on Facebook, she clicked on it. The bride-to-be messaged April Keller, owner of Queen Bee Photography - Stillwater, who she said quoted her 0 for 100 photos. "I saw her pictures on Facebook and they looked good," Barney said. It was a photo of a bride in her wedding dress surrounded by her bridesmaid in pink dresses that caught her eye. Queen Bee's post said "Wedding Samples" and showed several other stunning wedding photos. An online image search found the photos were on Pinterest and linked back to websites for designers, like Hayley Paige and Jenny Yoo. Barney did not know that at the time she booked.She said she met up with Keller before the wedding and provided her with a list of about 40 photos she wanted, including shots with her bridesmaids, close family, of her cake and so on. The two also agreed Keller was also going to be in charge of taking photos at a photo booth at the reception. August 1 was her big day. She said that was the day she started worrying. "She was trying to take pictures off of his flash," Barney said about Keller. "She was waiting for him to take a picture and whenever he would take a picture, she would take a picture."At the wedding, Barney said Keller admitted she was having camera issues and her flash did not work. Barney said she was worried about her photos from that moment on. "She messaged me [after the wedding] and asked if I could get the pictures my 10-year old niece took so she could edit those," Barney said. Barney was sent a handful of pictures through Facebook messenger but not near the 100 she paid for. "There are only three that are good pictures," the bride said. "They are pictures that I could have taken." In Facebook messages provided by Barney, Keller admits the pictures did not turn out well. It was heartbreaking news for the bride because she had family fly in from out of state for the occasion.As a consolation, Barney said Keller offered her a free family photo shoot with her children and grandchildren. On the day of the shoot, about 10 members of Barney's family went to the location they chose in coordinating outfits, but Keller did not show up. "I didn't think I could be more hurt than I was after my wedding and that happened and then I just gave up," Barney said. Keller said over the phone that her husband had health issues after Barney's wedding. She also said she is not operating Queen Bee Photography any more. A post on the business's Facebook page a day after a reporter spoke to Keller on the phone said, "I'm closing this company to open the chapter of my life if you get an invite from me please accept."We found a new photography business that her name and phone number are listed on called A-game Photography. "You get what you pay for," Barney said. "You get what you pay for. If you're going to try to save money on any part of your wedding, don't let it be the photographer." 3367
