A single, small slug has been blamed for a massive power failure that brought part of Japan's high-speed rail network to a standstill last month.An estimated 12,000 passengers were delayed on May 30, after power was cut on lines operated by rail company JR Kitakyushu, in the country's southern Kyushu region.The outage occurred during peak commuter time, at 9.40 a.m, forcing the company to cancel a total of 26 trains.Japan is famous for its large network of efficient high-speed trains, which run the length of the country and carry thousands of passengers every day.During a later inspection of the network's electrical equipment, the company's engineers discovered a dead slug, measuring about 2 to 3 centimeters (0.7 to 1.1 inches) long.According to a company spokesman, the slug had burned to death after touching an electrical cable leading to the mass power failure.Although it was discovered on May 30, shortly after the outage, the reason for the disruption wasn't revealed for more than a month.Local media first reported the unusual cause of the transport chaos on June 22.A JR Kyushu spokesman told CNN that the slug had got in through a gap in the power box."We have not heard of power outages caused by slugs in recent years," a spokesman said Monday."If we find such a gap when inspecting equipment (in the future), we will fix them." 1363

Actor-comedian John Witherspoon, who memorably played Ice Cube’s father in the “Friday” films, has died. He was 77.Witherspoon’s manager Alex Goodman confirmed late Tuesday that Witherspoon died in Los Angeles. No cause of death was released.The actor had a prolific career, co-starring in three “Friday” films, appearing on “The Wayans Bros.” television series and voicing the grandfather in “The Boondocks” animated series. His film roles included “Vampire in Brooklyn” and “Boomerang,” and he was a frequent guest on “Late Show with David Letterman.”For many his most recognizable role was “Pops,” Ice Cube’s father in the stoner comedy “Friday” and its two sequels, a crude but affectionate father trying to guide his son to be better.“Life won’t be as funny without him,” Ice Cube said in a Twitter post late Tuesday, adding that he was devastated by news of Witherspoon’s death.Regina King, who appeared as Witherspoon’s daughter in “Friday” and also voiced both of his grandsons in the animated series “The Boondocks” called him her “comedic inspiration” on Twitter.Goodman referred to a family statement issued to the website Deadline that said the family was in shock over Witherspoon’s death.The statement says Witherspoon, who was born on Jan. 27, 1942, is survived by his wife, Angela, and sons JD and Alexander.JD Witherspoon tweeted that he was happy for all the great times he and his dad had together.“We’d roast each other like homies more than Father & Son, and I really liked that. He was my best friend & my idol,” JD Witherspoon posted. “Love U Dad...I’ll miss u.” 1605

America has a deadly addiction to opioids, and Aimee Sandefur has both the emotional and physical scars to prove it.“I got them right there,” she says, pointing to track marks on her arm. “I have abscess. That was an abscess where they had to cut my arm open.”Sandefur has overdosed dozens of times, saying she’s lucky to be alive.“I overdosed 35 times, and by the grace of God I’m clean and sober now,” she says. “I didn’t think I was going to make it.” In Dayton, Ohio, local leaders are calling opioid and heroin abuse a national epidemic. “I described it then as I do now as a mass fatality event,” says Montgomery County Coroner Dr. Kent Harshbarger. Dr. Harshbarger says in 2017, there were so many opioid-related deaths that his morgue ran out space to the store all the dead bodies.“Our numbers were astronomical,” he says. “We ended up with about 566 overdose deaths in 2017. But we’re a regional center, so we probably ended with 1,400 overdose deaths that we handle in 2017.” During that time, Dr. Harshbarger says up to 75 percent of all the cases his team handled were overdoses. Now, that number is down to 40 percent.“Oh my God. America has a huge problem with opioids,” says Helen Jones-Kelley, executive director of the Montgomery County Alcohol, Drug Dddiction & Mental Health Services. “Even though we’re seeing some of the numbers begin to drop, it hasn’t decreased the overall problem by any stretch.” Jones-Kelley says despite a decrease in overdoses people are still using and still dying from these drugs. In an attempt to keep users alive, her team has now changed its approach. “Before we used to just turn our heads. Now, we get involved,” she says. “We’re giving people information, so hopefully they won’t use but if they do, they use in a way that they won’t die.” Also helping to save more lives is the access to more NARCAN for more people.Some, however, say saving an addict only gives them another chance to do more drugs. “It’s a drug that, unfortunately, once it gets you it gets you,” says former opioid-turned-heroin user Daniel Duncan.After his prescription of pills ran out, Duncan turned to the streets to fill the void.“A lot of people--when they found out or I told them--they were like, “Not you, man. You’re black,’” he says. “It doesn’t discriminate.” After years of lying and stealing to feed his fix, Duncan was finally able to kick his opioid addiction, but only after serving time in jail. “I say there is hope. Don’t give up. Don’t give up at all,” he says. “You deserve much more than that. You’re better than that. It can be done.” While some can overcome their drug dependencies, others say they lost things that they can never get back.“My mom came beating on my door, and I’m like, ‘Mom, I don’t have no crack,’” Sandefur says. “And she’s like, ‘I know you have crack’ and I’m like, ‘Mom, I don’t have no crack; I have heroin.’”Sandefur says she unintentionally gave her mom a lethal dose of heroin. “Next thing you know I hear screaming downstairs, and my mom is lying on the living room floor blue in the face dead,” she says.Since her mother’s death, Sandefur says she hasn’t used drugs but that she ended her addiction too late.“I wish my mom was still here,” she says. 3246

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 romance scam has claimed another victim, a woman hoping for some companionship, but whose Mr. Right turned out to be all wrong.Petronica Williams thought she found the man of her dreams on Instagram, a great looking, New York City-based fitness trainer."He inboxed me on Instagram," Williams said, "saying 'hey gorgeous, I want to get to know you.' "Her Romeo sent videos, showing him training some of the stars of the VH1 reality show "Love and Hip Hop." Williams couldn't believe he was interested in her, but he was.She says their messaging got more and more intense, and he wanted her to come to his fitness studio in New York. Unfortunately, first he had to go to Africa on a short assignment.That's when trouble developed.New friend needs money to get home"He said he was over there working as a fitness trainer on a contract," Williams said. "But he was stranded and needed a way to get home."He needed money fast -- specifically 0 for a plane ticket home from Africa. He promised to return the money to her as soon as he got back to the U.S.So a love-struck Williams wired it to him through MoneyGram, and figured he was on his way.But he soon messaged her again, saying the Republic of Benin, in West Africa, would not let him leave unless he paid his income taxes first."They won't let me go home because I owe ,500 in taxes," the trainer messaged her.Before Williams took the time to realize what she was doing, she said, "I sent him a total ,076." Only after he stopped texting her back did she start suspecting she had been duped, that her fitness trainer may have been conning her from West Africa all along. 1644
