Despite being the most watched sport in the country, fewer young people are playing tackle football. And while 7th grader Andrew Ek dreams of playing in the NFL, Brigid Ling worries about what the sport can do to Andrew’s and her own son’s brains. “When our oldest son was 8 he was begging us to move on from flag football to play tackle,” Ling said. “And we just weren’t ready for him to play tackle football at that age.” A new survey found participation in tackle football for kids 6 to 12 years old, dropped more than 17 percent over the past five years. A big reason for the shift: brain injuries. After more than a decade of research, there’s hard evidence of a direct link between football and CTE - a brain disease caused by repeated hits to the head. “We just felt there had to be a good interim step for kids to play,” Ling said. So rather than find a new sport for their son to play, Ling and her husband created one. “We created TackleBar as a way to allow kids to make a transition step from flag football to tackle football,” she said. In TackleBar, players hit but they don’t tackle each other to the ground. The goal is to wrap up and rip off foam bars harnessed on other player’s lower backs. Tacklebar coach Logan U’u grew up in a city that embraced hardnose football. “Playing football in Oakland, man, you got guys like Marshawn Lynch out there in your league,” U’u said. “We’re just little kids just cracking heads every single play.” Earning a football scholarship to the University of Minnesota, U’u knows about the sport’s rewards. He also knows about the risks like concussions. “You become nauseated to the point where you feel like you’re going to throw up and maybe you do throw up,” he said. “And then you feel like you want to cry but you can’t because you’re so confused. It’s a very bizarre feeling.” U’u says TackleBar teaches players proper tackling techniques and ultimately better prepares kids to transition to real take downs. Neurosurgeon and University of Minnesota researcher Uzma Samadani says TackleBar is much safer than both tackle and even flag football, and she has the research to prove it. “We published this paper in the Orthopedic Journal of Sports Medicine,” she said. “Basically, what we found was that the injury rate was seven-fold lower in the TackleBar kids versus the other kids” For two seasons, Samadani tracked 1,000 football players ages 9 to 15, and her findings showed a big spike in safety. “I think TackleBar makes athletes safer for two mechanisms,” she said. “One is reducing head-to-head contact and other is reducing head-to-ground contact.” Despite the study, Samadani says banning contact sports isn’t the ultimate answer – safer options are. “Now that we understand that the chronic effects of neurotrauma exist and they’re very serious we have to prevent it from happening in the next generation,” she said. Now entering its fifth season, TackleBar is attracting a new generation of young football players. “Last year we were over 8,000 kids in over 200 communities,” said TackleBar CEO Tim Healy. Healey says they plan on continuing to expand to teams across the country with the hope that TackleBar can reverse the trend and ultimately bring kids back to old-school football – when they’re ready. “It pains me when I see these schools where the numbers are down so much,” he said. “This is a way we can save the game.” 3447

ARAPAHOE COUNTY, Colorado — An argument over not getting recognition for testing done at Aurora West College Preparatory Academy led one of the school’s deans of instruction to bring a gun to campus and threaten school officials earlier this week, an affidavit released Friday reveals. Tushar Rae, 30, was arrested Wednesday and remains in Denver jail on suspicion of carrying a weapon on school grounds, a class 6 felony; as well as carrying a concealed weapon, a class 2 misdemeanor. His bond was set at 0,000. The affidavit states Principal Taisiya “Taya” Tselolikhina had an argument with Rae on Tuesday over testing that the school was administering to students “and about not receiving acknowledgement and recognition he felt was owed.” The following day, Tselolikhina received a text at around 2 p.m. from Rae, telling her to meet in his office after the dean of instruction didn’t show up to school the whole day, and didn't inform anyone he was going to be absent.Once in the office, Rae reportedly pulled a black handgun from his waistband and placed the gun on the counter. Rae then said, “Try and f—k with me. You shouldn’t have said what you said. I don’t want to hurt you. I’m going to hurt all the people around you,” according to the affidavit. He then said he was going to “shoot the kneecaps off of Jessica and Denise.” Jessica Rodriguez is an assistant principal at the school and Denise Huber is another dean of instruction. The probable cause statement notes he then asked the principal what she was going to do about it. "I came prepared,” Rae allegedly told Tselolikhina before he patted his pocket adding that “he had two extra rounds.” Rae then told the principal to walk away or he would “shoot the next person outside the door,” police documents state. As he made the statement, there was a knock on the door. Rae then reportedly picked up the gun and placed it back into his waistband and answered the door. On the other side were two students and the report states Rae had a brief talk with them. It does not state, however, what the dean of instruction told the students. Tselolikhina then left Rae’s office and began to place the school on lockdown, according to the affidavit. The incident “prompted a large scale police call for service and numerous officers responded to the school,” the probable cause statement states. Investigators said one of the responding officers talked with the principal while another was on the phone with the suspect, who did not initially tell the officer where he was. Rae then told the officer that some of the school staff had been harassing him, but the suspect did not provide further details to the officer during their conversation. According to the affidavit, Rae also admitted to sending text messages earlier “that he should not have sent,” but it’s unclear what the content of those message was, as the suspect did not provide further details to police. The probable cause statement states Rae “expressed concern” about the school being on lockdown and told the officer on the phone he wanted the lockdown lifted so the soccer team could play a game scheduled for later that day. The suspect then told the officer he was at his house and police went to his address, where they found a Remington handgun and three magazines in Rae’s bedroom cabinet. He was arrested and held on a bond on suspicion of felony menacing and misdemeanor interference with staff, faculty, or students of educational institutions, but posted pond and was released before he was able to be issued a restraining order. His bonding out caused Aurora Police to send officers to Aurora West College Preparatory Academy as well as the homes of school staff to make sure they were safe. Rae was then booked into Denver’s Downtown Detention Center on Thursday on a fugitive of justice hold from the Arapahoe County Sheriff’s Office. Initial communications to parents didn’t tell the whole story Communications to parents following the lockdown on Wednesday told a different story about what took place inside the school as hundreds of kids were still in class. A call from the principal made to parents on Wednesday stated that both Aurora Public School officials and the Aurora Police Department investigated a possible threat at the school and that “there were rumors of an armed individual in the area” – hours after the district, school administrators and the school principal were aware Rae was on campus allegedly armed with a gun and reportedly making threats.A second call from the school on Thursday state that after school officials learned about the allegations, “we promptly placed the employee on administrative leave."According to the statement from the school, Rae is not allowed on school grounds pending the outcome of the criminal investigation.Students walk out after learning what happened Dozens of students walked out of class at the school Friday morning, saying they were not told that Rae allegedly brought a gun to the school Wednesday and made the threats. 5054

The Cleveland Indians are moving forward in the process to examine and possibly change the team name and will be meeting with Native American leaders to help determine the best path forward.Indians owner Paul Dolan announced Thursday that as part of the organization's continuous efforts to discuss the team name, there have been productive meetings earlier this week with manager Terry Francona and numerous players to discuss the name, as well as social justice and racial equality issues.To continue examining the best path forward, the organization said it will be engaging with Native American leaders to “better understand their perspectives,” in regards to the team name.The organization will also hold discussions with civic leaders and said it will continue to listen to the opinions and perspectives of players, fans, partners and employees.“We feel a real sense of urgency to discuss these perspectives with key stakeholders while also taking the time needed to ensure those conversations are inclusive and meaningful,” Dolan said. “We will continue to share periodic updates as we make progress. In the meantime, we are excited for our team to return to the field to continue our pursuit of a World Series Championship.”Dolan said that the organization appreciates the “passionate response” it has received over the last few weeks since announcing it would be discussing a possible name change. WEWS' Camryn Justice was first to report this story. 1482

AUSTIN, Texas – Inside a restaurant called “The Pita Shack,” Ayman Attar Bashi recreates part of his culture through the food served in his restaurant. “We are lucky,” he said. He and his family are lucky because a decade ago, they fled violence in Iraq, becoming refugees and resettling in Austin, Texas. “To be a refugee is not a choice,” he said. “Not a choice.” Refugees like Ayman, though, may no longer be able to count on Texas for a fresh start. Governor Greg Abbott said the state has already done more than its fair share. In a letter to Secretary of State Mike Pompeo, Gov. Abbott said that since 2010, “…roughly 10% of all refugees resettled in the United States have been placed in Texas.” He added that, “in addition to accepting refugees all these years, Texas has been left by Congress to deal with disproportionate migration issues resulting from a broken federal immigration system.” “There had been 41 other governors that had had come out and said, ‘yes, our state we would love to continue to accept refugees’ and that was a mix of Democrats and Republican governors, and so Gov. Abbott was the very first who had said no,” said Russell Smith, with Refugee Services of Texas, the largest resettlement agency in a state. Last year, Texas took in 2,227 refugees – the most of any state. It was followed by Washington, with 1,930 and California with 1,802. Overall, America is admitting fewer refugees. Back in 2016, President Barack Obama set a limit of 110,000 for the 2017 fiscal year. This year, President Donald Trump is setting a limit of 18,000. Though a judge put a temporary stop to the Texas plan, the potential for refugees to be rejected looms large here. “Every action has negatively affected resettlement at the same time,” Smith said. Whether the plan eventually goes through – or gets permanently rejected by the courts – remains to be seen. Back at his restaurant, Ayman says he and his family feel safe and welcomed in Austin. “You’re an active element in this community because we’re hiring people, we are providing people with good food, spread our culture – at the end of the day, you feel like you are doing a lot of good things in this community,” he said.The Trump administration has not said yet whether it will seek to appeal the federal judge’s decision, which stopped Texas from refusing refugees. 2356

BALTIMORE, Md. – In looking for creative inspiration, engineering student Qiyuan Fu finds it in a box, with an interesting occupant. Inside: a real, live snake. “We can definitely learn something from them,” Fu said. The snake is a Kingsnake, which is native to deserts in California and Mexico and serves as the model for a new robot, developed in a mechanical engineering lab at Johns Hopkins University. “We added this one directional wheel, so it can only rotate in one direction,” said Fu, as he demonstrated how the robot moves. The “snake robot,” and its colleague, the “roach robot,” are so-called “bio-inspired robots” – taking their cues from mother nature. “We studied snakes here because they are exceptionally good at moving through almost any terrain,” said Johns Hopkins assistant professor Chen Li. Li said it’s an idea with practical applications: the robots could potentially help in search and rescue, by making their way through tight spaces to find people trapped in rubble. “People have actually tried to build snake robots for several decades,” he said. In the past, though, the robots fell short once they left the lab environments, unable to make it through different types of terrain. This time – using specially positioned cameras – they’ve observed how the snakes and roaches move across different surfaces and attempted to mimic what nature already does so well. “What's really unique about our work is that we focus on understanding the physical principles – starting by looking at animals,” Li said. “And then by understanding such principles, we can apply them to the to the robot.” The snakes have 200 vertebrae; the snake robot has 20 segments. It’s progress, these engineers say, with more to go. “There’s still going to be a lot of challenges ahead,” Li said.The engineering lab is now looking into modeling robots based on lizards. That’s because of their ability to leap across surfaces, which could further help robots make their way across uneven terrain. 2008
