You can find weights, and workouts at any gym. But for gymgoer Amanda Hall, she finds something else at her gym she can’t find anywhere else. At The Phoenix, Hall is a fitness coach. She found the gym four years ago after trying over and over to beat her addiction to alcohol. “Every time one of those things didn't work out, I just ended up feeling more and more alone,” she says. But not at The Phoenix, which serves as an active sober community for its members suffering from substance abuse. “Nobody really cared about like where I went to treatment, if I went to treatment, if I go to one program, if I don't go to another program,” she says. “The only thing that was important was that we all just wanted to come together and have fun.” Gym founder and executive director Scott Strode started The Phoenix after his own battle with addiction.“I found my way into a boxing gym, and there was something really special about getting in the ring for the first time and being in there with other guys that were in recovery,” Strode says. “There were a couple sober boxers there and they became my support network.”To attend, you only need to be sober for 48 hours. “It burned and from its own ashes it rose again, and that's the story of so many people that come to our program,” he says of the gym’s name. “So, the name’s a perfect fit.” Phoenix gyms are in 20 states across the country, and they’re free! “There are so many programs that if you don't have the right insurance or you don't have enough money to self-pay or whatever else, you can't get access to treatment,” Strode explains. “Phoenix, if you can open the door, you can be part of it.” That incentive made it easier for Andrew Brough to come to the gym’s Denver location four years ago, while battling his addiction to opioids. Now, as manager of the Denver Phoenix chapter, Brough helps others in the same position he was in. “There was a lot of people that, like, help me along my journey that allowed me to be in this position,” Brough says. “And now, I hope that I can do that for somebody else.” 2080

(CNN) -- Artificially-generated faces of people who don't exist are being used to front fake Facebook accounts in an attempt to trick users and game the company's systems, the social media network said Friday. Experts who reviewed the accounts say it is the first time they have seen fake images like this being used at scale as part of a single social media campaign.The accounts, which were removed by Facebook on Friday, were part of a network that generally posted in support of President Trump and against the Chinese government, experts who reviewed the accounts said. Many of the accounts promoted links to a Facebook page and website called "The BL." Facebook said the accounts were tied to the US-based Epoch Media Group, which owns The Epoch Times newspaper, a paper tied to the Falun Gong movement that is similarly pro-Trump.The publisher of the Epoch Times denied that Epoch and The BL were linked in emails to the fact-checking organization Snopes earlier this year.In a statement released after this story initially published on Friday, Epoch Times publisher Stephen Gregory said, "The Epoch Times and The BL media companies are unaffiliated. The BL was founded by a former employee, and employs some of our former employees. However, that some of our former employees work for BL is not evidence of any connection between the two organizations."The BL is a publication of Epoch Times Vietnam. As can be seen in archived pages of The Epoch Times website, Epoch Times Vietnam was no longer listed as part of Epoch Media Group in October 2018."In response, a Facebook spokesperson told CNN Business that executives at The BL were active administrators on Epoch Media Group Pages as recently as Friday morning.The dystopian revelation of the use of artificially-generated images in this way points to an increasingly complicated online information landscape as America enters a presidential election year. Silicon Valley and the US intelligence community are still struggling with the fallout from widespread online interference in the 2016 presidential election.The Facebook accounts used profile pictures that appeared to show real people smiling and looking directly into a camera. But the people do not and have never existed, according to Facebook and other researchers. The images were created using artificial intelligence technology. The same basic methods are used to produce deepfake videos — fake videos that the US intelligence community has warned could be used as part of a foreign disinformation campaign targeting Americans.Other fake accounts that were part of the same network used stolen pictures of real people, according to the social media investigations company Graphika and the thinktank the Atlantic Council. Facebook provided information to Graphika and the Atlantic Council for analysis in advance of Friday's announcement.The accounts were used to run dozens of pro-Trump Facebook groups with names like "America Needs President Trump," and "WE STAND WITH TRUMP & PENCE!," according to Graphika and the Atlantic Council.The fact-checking organizations Snopes and Lead Stories had reported in recent weeks and months about the use of artificial images on Facebook that were part of this network of accounts. Snopes published a story last week criticizing Facebook's apparent inaction on the issue. Facebook said Friday it had "benefited from open source reporting" in the takedown but said that its own systems that monitor for coordinated and inauthentic behavior had proactively identified many of the accounts.In a joint report on their findings, Graphika and the Atlantic Council outlined how they were able to determine which of the profile photos had been generated using artificial intelligence. "This technology is rapidly evolving toward generating more believable pictures, but a few indicators still give these profile pictures away," they said.Images generated using artificial intelligence, specifically by a machine-learning method known as a GAN, or generative adversarial network, are "notorious for struggling with features that should be symmetrical on the human face, such as glasses or earrings, and with background details. Profile pictures from the network showed telltales of all three."GANs consist of two neural networks — which are algorithms modeled on the neurons in a brain — facing off against each other to produce real-looking images. One of the neural networks generates images (of, say, a woman's face), while the other tries to determine whether that image is a fake or a real face.While experts were able to spot these telltale signs on close inspection, it is likely the regular Facebook user would not.Over the past year, a number of websites have emerged online that create fake faces using artificial intelligence.Researchers from Graphika and the Atlantic Council could not conclusively determine if the people behind the fake accounts had used artificial pictures from these public sites or had generated their own.In their report released Friday, Graphika and the Atlantic Council said, "The ease with which the operation managed to generate so many synthetic pictures, in order to give its fake accounts (mostly) convincing faces, is a concern. Further research is needed to find ways to identify AI-generated profile pictures reliably and at scale, so that platforms and researchers can automate their detection."Connection to Epoch Media GroupIn all, Facebook said Friday, it had removed a network of 610 Facebook accounts, 89 pages, 90 groups, and 72 Instagram accounts. About 55 million accounts followed one or more of the pages, and the vast majority of followers were outside the United States, Facebook said. Facebook did not say if all of all these followers were real — some of them may themselves have been fake accounts.The network of pages removed on Friday had spent almost million on Facebook ads, according to Facebook.Facebook's investigation primarily focused on "The BL" (The Beauty of Life) — a set of Facebook pages and a website that says its goal is to "present to the world the most beautiful aspects of life."The pages often shared pro-Trump and anti-China content.On its website, The BL outlined the dangers of "inaccurate and degenerate information" that it said "can be easily channeled toward vulnerable or uninformed people."The purpose of the fake accounts, including those using fake faces, appears to have been to promote links to The BL's website and Facebook pages, Ben Nimmo, director of investigations at Graphika told CNN Business on Friday.Facebook said the fake accounts were tied to the US-based Epoch Media Group and "individuals in Vietnam working on its behalf." The company did not outline precisely how it made the connection, but in recent years Facebook has hired a team of investigators to find fake accounts on the platform.The Epoch Times newspaper is part of the Epoch Media Group. The newspaper has almost 6 million followers on Facebook. Nathaniel Gleicher, Facebook's head of security policy, told CNN Business Thursday that Facebook was not suspending the newspaper's account but investigations into Epoch's behavior on Facebook were ongoing.Snopes reported earlier this month that the publisher of the Epoch Times denied that The BL and Epoch were linked.In August, Facebook banned ads from The Epoch Times after an NBC News investigation detailed how the newspaper was secretly running pro-Trump Facebook ads under alternate accounts. The Epoch Times' publisher said in a statement to NBC News, "The Epoch Times advertisements are print-subscription advertisements describing our paper's reporting — a popular practice of many publishers — and every one of these ads was approved by Facebook before publishing."A Facebook spokesperson said the company shared its findings with Twitter and Google, which owns YouTube.A Twitter spokesperson confirmed in a statement Friday, "today we identified and suspended approximately 700 accounts originating from Vietnam for violating our rules around platform manipulation — specifically fake accounts and spam.""Investigations are still ongoing, but our initial findings have not identified links between these accounts and state-sponsored actors," the spokesperson added.Google did not immediately respond to CNN Business' request for comment. 8341

(AP) - There were first-time voters and straight-ticket voters and some who, this go-around, switched sides. They went to the polls considering the caravan of migrants trudging across Mexico, their health insurance and their paychecks, an impotent Congress and the nation's poisonous political culture that has divided even families and friends along party lines.More than anything on this Election Day in America, in a midterm contest like no other before it, voters cast their ballots with one man in mind: President Donald Trump."I would have never thought this country would elect Donald Trump as president," said Kimball Blake, 61, a Knoxville, Tennessee, energy engineer who called Trump's presidency a "profound factor" in his decision to vote Democratic in his state's U.S. Senate race. "It got me out to vote this year, not that it usually takes that much motivation."Americans turned out in droves Tuesday — some lining up before the sun rose, some standing for hours or braving pouring rain or snow — to vote in an election that will determine control of Congress and render a verdict on Trump's first two years in office. The outcome could redefine the nation's political landscape for months and years to come.Democrats need to gain 23 seats to take control of the House of Representatives, and hope to ride the wave of liberal fury that organized after Trump's surprising victory in 2016."My loathing for him knows no bounds," said Kathleen Ross, a 69-year-old retired professor, as she cast her ballot for Democrats in Olympia, Washington, confident the country will eventually reject Trumpism and the divisive governing it represents. "I tend to think the arc of the universe bends toward justice, so I don't become discouraged."Trump has sought to counter some of that rage by stoking anger and fear in his base. In recent weeks, he's put the spotlight on a caravan of Central American migrants fleeing poverty and violence that he calls "an invasion" of criminals and terrorists. He ran an advertisement about immigration so racially incendiary that all three major cable news networks, including Fox News, either refused to air it or eventually decided to stop showing it.Among some Republican voters, that message resonated."What's going on right now is pretty scary to me, at the border, with all those people coming, and I don't think I'm hardhearted or anything," said Patricia Maynard, a 63-year-old retired teacher in Skowhegan, Maine.When she voted for Trump in 2016, the blue-collar economy was her primary concern. Now, she said, immigration tops the list. She laments that Congress has so far failed to pass legislation to build the wall Trump promised along the border. So she voted for Republicans Tuesday, with hopes they would retain control and push Trump's agenda.In Westerville, Ohio, Judy Jenkins cast her vote at a suburban church and said she supports Trump's decision to send military troops to the U.S.-Mexico border to intercept the caravan — a move critics say is unnecessary and a political stunt, given the migrants are traveling mostly on foot and remain hundreds of miles away."We don't know what that caravan is bringing," said Jenkins, who describes Trump as "my guy," though she concedes she cringes at some of what he says. "Who's perfect?" she said.For many on the other side of the political aisle, the caravan controversy singularly represents what they find unconscionable about Trump's presidency."He's always used the scare tactics and found an enemy to band against," said 24-year-old Enrique Padilla of Grand Rapids, Michigan. Padilla considers his own family an example of the American dream. His father migrated from Mexico as a laborer at 18, raised his family, and now Padilla has a college degree. The president's persistent demonization of immigrants galvanized him and many of his peers to vote against Republicans, Padilla said.In Louisville, Kentucky, Mary Cross, a 64-year-old African-American voter, said she believes Trump uses issues like immigration to distract from more important topics, and in doing so infuses fear and distrust into society. "It's manufactured fear. It's uncivilized. It's just a bunch of mayhem for nothing. There's no substance to this," said Cross, who thinks the country should be talking about the Republican-led campaign to overturn the Affordable Health Care Act that protects people with pre-existing conditions.Cross, and others, expressed a heightened sense of unease and sadness about the state of America's political climate. The election comes just days after a series of hate crimes and political attacks, including the arrest of a man who mailed pipe bombs to Trump critics whom the president often derides as "evil," ''un-American," and "the enemy." Where Cross lives, a gunman tried to get into a majority-black church but found the doors locked and went instead to a nearby grocery store, where he gunned down two elderly African-American shoppers in what police are calling a hate crime."Our president, with his rhetoric and vulgar language, continues to throw fuel on the fire. Racism has always been around, but since he's been in office, people feel free to express it and feel good about it," said the Rev. Kevin Nelson, the pastor of the Louisville church the gunman tried and failed to enter. The congregation has received cards and calls from all over the country, from Christians and Jews and Muslims and atheists — and also a white man in Texas who said he was sorry about what happened and promised to cast his ballot against the rhetoric he believed to be igniting hate."You're always hoping that somehow, some way, someday, it's going to change," Nelson said before he voted Tuesday. "I'm hopeful that it could this time."Many voters said the political tribalism has infested their everyday lives. The Simon Wiesenthal Center released a survey on the eve of the election that showed a quarter of Americans have lost friends over political disagreements and are less likely to attend social functions because of politics.Odell White, a 60-year-old African-American conservative, described the state of the country's political discourse as veering toward civil war."We are dangerously close to that type of mentality — brothers fighting brothers. That's how bad it is," said White, who supports Trump and voted Tuesday for Republicans. Friends have turned away because of his political leanings. White said he doesn't like the president's aggressive rhetoric, but he's willing to overlook it because of the booming economy and the two conservatives Trump installed on the Supreme Court.But Trumpism has proved too much for some.In Portland, Maine, Josh Rent, 43, a small business owner and registered Republican, said he voted mostly for Democrats all the way down the ballot for the first time to protest Trump, who he believes is unnecessarily dividing Americans for his own gain."He's just nasty," he said. "Life doesn't have to be this nasty, in my opinion."___Also contributing were AP reporters Steve Megargee in Tennessee, Jocelyn Noveck in New York, Rachel La Corte in Washington, Margery Beck in Nebraska, Kantele Franko in Ohio, Summer Ballentine and Jim Salter in Missouri, Matt Volz in Montana, Hannah Grabenstein in Arkansas and Chris Chester in Maine. 7296

  

"Flippy," the burger-flipping robot introduced recently at a Pasadena, Calif., burger restaurant, has been taken offline after one day on the job.The robot was taken off the line, in fast-food terms, at CaliBurger, BBC News reported, after it was unable to keep up with demand. Miso Robotics introduced the robot as a potential replacement to human cooks.So the burger-flipping robot has been switched off until coders can update it.Interest and news about Flippy's "hiring" created an increased demand at the restaurant, leading to more orders than it could handle.CaliBurger is reportedly working with staff to make sure the kitchen is working around Flippy as efficiently as possible as well. The restaurant hopes to eventually deploy Flippys in more of its locations.Miso Robotics says Flippy can detect when raw burger patties are placed on the grill and monitors each one. A cloud-based software from the company keeps track of the cook time and alerts workers when it's time to dress the burger patty.Flippy will be able to cook up to 2,000 burgers a day, the company touts. Here's a look at how the robotic arm works: 1163

  

With dwindling resources and a lack of medical supplies, health care providers around the country are concerned about handling the surge in COVID-19 patients.But behind the scenes, nonprofits like Direct Relief are working around the clock to help doctors and nurses on the frontlines of the pandemic.Headquartered in Santa Barbara, California, the nonprofit responds to disasters every day of the year.But longtime employees like Andrew MacCalla sensed early on that this one was unlike the rest.“Back in January, when we got asked to send personal protective gear, like masks and gowns to China – where it’s mostly all made – we started questioning, this is something different," she said.MacCalla is vice president of Emergency Response at Direct Relief. He says the requests were strange because China doesn’t usually ask them for help.“But pretty quickly we realized that they were truly stocked out, this was something that was growing rapidly,” said MacCalla. The nonprofit has one of the largest N-95 stockpiles in the country, but their supply is quickly being depleted as they ship out thousands a day.Two weeks ago, they had about 500,000 masks left, and now they’re down to around 250,000.But as the situation improves in China, they’re hopeful orders placed on hold will begin to go out in a few weeks.The nonprofit is working on getting ahead of the crisis, ramping up stockpiles of oxygen concentrators, medications, and ventilators.Since the outbreak began, Direct Relief’s sent supplies to 31 countries, including over 1 million masks, 48,000 gowns, and over 1.6 million gloves.“These situations can feel so overwhelming, and it feels like it’s out of control and there’s nothing we can do to stop it. But really there is something we can do to stop it. We have a robust supply here,” said senior emergency response manager Cydney Justman.With every shipment, health workers receive not only supplies, but the encouragement to keep fighting. Direct Relief relies on donations, 2006
