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 number of koalas that were rescued during January's massive Australian wildfires were returned to the wild earlier this week, Science for Wildlife announced. The four adult koalas and a baby joey were returned to the Blue Mountains region of Australia. A total of 12 koalas were rescued and the group is working on returning all 12 this week. The San Diego Zoo was involved in rescuing and returning the koalas. The wildfires 2.5 million acres of Australian land. Experts estimate that nearly one-third of the koala population in Australia perished with the wildfires. 583

Aimee Bouc knew Austin Eubanks the way few people did.“He was not so much the person he was on TV. He wasn’t so serious," she says. Aimee was once married to Eubanks. The two met as teens and went on to have two children. Many knew Eubanks as a survivor of the 1999 Columbine shooting. He was shot in the hand and knee in the attack. He battled the impact of addiction and trauma over the 20 years that passed since the shooting. “I turned to substances to cope. That was the answer for me," Eubanks said in an interview in April for a story marking two decades since Columbine. Eubanks became a national spokesperson. He gave talks about his struggle becoming a beacon for others struggling the way he did. "I think it’s really important that not only as survivors of trauma, but survivors of addiction, speak out and share their stories," Eubanks said in April, "You never know when your story is going to change the life of somebody else."Austin wasn't able to fully escape the darkness of addiction. In May he was found dead in his home, the victim of an overdose. "There was so much pressure put on him to be this perfect person in the eyes of the world," Aimee says. "He didn’t feel he could actually go and get the treatment when he did go back to it.”In the months leading up to his death, Aimee suspected he was using again. “I believe there was always a fight. I don’t believe he was always using, believe that was more recently, Aimee says. "It never stops being a struggle. I don’t think addiction is something you can just stop struggling one day it’s always a work in progress." Now, as opioid companies face several lawsuits over the opioid crisis, Aimee says Austin would want more. “He wouldn’t want it to stop there," Aimee says. "In America, I believe strongly we need to start tackling and treating mental health and anxiety, depression, anything, any kind of problems. Almost like a dental check up in terms of insurance."Aimee knows progress in fighting the opioid crisis is too late for Austin, but she believes his life will still help others. "His story and the power behind Columbine really put him front and center of the opioid addiction and his TED talks and everything that he did," she said. "He brought a complete level of awareness and helped so many people and I've read their comments on how he helped them shape their lives. It just brought me tears of joy.”Aimee recently launched 2431

A reported tornado tore through a city in Oklahoma, killing at least two people and leaving multiple others injured, authorities said.A mobile home park in El Reno was "devastated," Mayor Matt White said."It's a lot of devastation here, it's leveled, it's just devastated, White said in a phone interview with CNN. "It's tore all to pieces, it was terrible."It is too early to tell whether the death toll will rise and the number of injured is still unknown, said Andrew Skidmore, a director at the Canadian County Emergency Management. Officials were going door to door to find victims and assess the damage after it touched down in the city late Saturday night.El Reno, with a population of about 19,000, is about 29 miles west of Oklahoma City.Rachel Garrison was in a mobile home when the storm hit, according to CNN affiliate 842
