Their youthful brains were developing normally, with no signs of developmental, psychological or neurological problems. None had ever had a concussion. But by the end of a single football season, 24 children between the ages of 9 and 18 who had more frequent impacts to the head showed signs of damage to brain development, new research says."Repetitive head impact exposure may have a cumulative effect in the rapidly developing brains of youth and high school football players," said study co-author Gowtham Krishnan Murugesan, a radiology research assistant at UT Southwestern Medical Center in Dallas, adding that the results mirror other recent findings.The study outfitted 60 youth and high school football players who had no history of head trauma or developmental issues with a head impact telemetry system that measures the magnitude, location and direction of impacts to the head. The researchers were not looking at whether the impact resulted in a concussion, only that impact occurred.The children were sorted into two categories: high cumulative head impact players (24) and low cumulative head impact players (36).Before beginning to play, each child had a resting state functional scan, known as an fMRI; the scans were repeated at the end of football season. The researchers were trying to see how exposure to repetitive hits affects the normal "pruning" process in the brain that occurs during adolescence."Pruning is an essential part of brain development," Murugesan said, comparing the process to how a tree needs to have dead or unneeded branches cut to keep it healthy and allow it to grow."Disruption in normal pruning has been shown to be related to weaker connections between different parts of the brain," he said.After comparing the functional MRI results to the player's level of impact, the researchers found that youth in the high-impact group had damage to their brains' pruning process after one season."Our study has found a significant decrease in gray matter pruning in the frontal default mode network, which is involved in higher cognitive functions, such as the planning and controlling of social behaviors, " Murugesan said.Although the "teenage years are a critical time for brain development, brain remodeling or synaptic pruning, this was a short-term study and did not follow the players longitudinally over several years. We don't really know the full application," said Dr. Julian Bailes, director of neurosurgery and co-director of the NorthShore University HealthSystem Neurological Institute, who was not involved in the research.Weill Cornell neurologist Dr. Richard Isaacson, who was also not involved in the study, called the research "early" and said the results don't necessarily "translate to a clinical or cognitive outcome." More research is needed to see whether the decline in brain pruning permanently affected the child's cognitive function or whether the brain's natural plasticity allowed it to repair itself."I would call this a pilot study," Isaacson said. "The call to action would be that we need more robust longitudinal studies with a pre- and a post-assessment of more than brain imaging. The study should also measure cognitive and neurological function and look for changes."As we learn more about the issue, Isaacson said, parents should do everything they can to limit contact in sports, "especially in practice before games, where studies show the majority of contact occurs." 3464

There is a web of connections between the Trump campaign, the anti-secrecy website WikiLeaks and the public disclosures it injected into the presidential campaign. Federal investigators are examining some of these relationships and whether any of them were part of an effort to coordinate with Russia's election-meddling efforts.On Monday, it was revealed that Donald Trump Jr. exchanged some private messages on Twitter with WikiLeaks during the 2016 presidential campaign. The news was first reported by The Atlantic and later confirmed by Trump Jr., who posted screenshots of the messages.A source familiar with the matter told CNN that Congress has known about these messages for a while and they came up during Trump Jr.'s closed-door testimony in September. 771

Three years ago, President Donald Trump used an expletive to describe NFL players participating in on-field protests against police brutality. Now, Trump said on Wednesday he would be supportive of Colin Kaepernick rejoining the NFL.Trump told WJLA-TV on Wednesday that “absolutely, he would” be supportive of Kapernick getting another shot in the NFL, assuming he can play well enough to earn a roster spot.“If he deserves it, he should,” Trump said. “If he has the playing ability. He started off great, and then he didn’t end up very great in terms of a player. He was terrific in his rookie year. I think he was very good in his second year. And then something happened. So his playing wasn’t up to snuff.“The answer is absolutely I would. As far as kneeling, I would love to see him get another shot. But obviously he has to be able to play well.”Trump has been harshly critical of players kneeling during the national anthem. He once said that the NFL should “Get that son of a b---- off the field right now” about players who kneel"It is about time that (NFL Commissioner) Roger Goodell of the NFL is finally demanding that all players STAND for our great National Anthem-RESPECT OUR COUNTRY," Trump said in a 2017 tweet.Kaepernick was among the first players to kneel during the national anthem in 2016 in hopes of bringing attention to the Black Lives Matter movement. Despite Kaepernick not getting re-signed in 2017, up to 200 NFL players participated in kneeling during the national anthem in 2017.Kaepernick later accused the league of collusion, and earned a settlement with the NFL for not getting signed.As tensions have grown in recent weeks since the death of George Floyd on Memorial Day, NFL Commissioner Roger Goodell expressed regret for being critical of the movement."We the National Football League, condemn racism and the systematic oppression of black people," Goodell said. "Absolutely I would," support @Kaepernick7 getting a 2nd shot in the @NFL -- @POTUS in my interview today on racism, policing, statues & yes--sports. #ColinKaepernick pic.twitter.com/0B83cNbesW— Scott Thuman (@ScottThuman) June 17, 2020 2151

Tinder's parent company Match Group is suing competitor Bumble, accusing the female-friendly dating app of patent infringement and stealing trade secrets.The lawsuit, filed Friday in Texas, says Bumble is virtually identical to Tinder, the app that popularized the swipe right to like, swipe left to dislike functionality.Bumble copied the "world-changing, card swipe-based, mutual opt-in premise" of Tinder, the lawsuit says.The complaint also says that Bumble's co-creators are ex-Tinder employees, and the app has rolled out two new features that were "learned of and developed confidentially while at Tinder."Bumble has become a fierce competitor to Tinder since it launched in 2014. Bumble's differentiating factor is that only women can make the first move. But Match confirmed last month it plans to launch that feature in its own app.In the complaint, Match says it "applauds Bumble's efforts at empowering women, both in its app and offline" and "cares deeply both about its women users and about women's issues generally.""This case is simply about forcing Bumble to stop competing with Match and Tinder using Match's own inventions, patented designs, trademarks, and trade secrets," it says.The lawsuit is the first time that Match Group, which also owns dating sites Plenty of Fish and Match.com, has enforced the patents it secured on swiping and double opt-ins for dating matches on Tinder, according to a company spokesperson.Tinder and Bumble have had a complicated history.Bumble was launched by Whitney Wolfe Herd, an early employee at Tinder.Wolfe Herd left Tinder in 2014 after alleging sexual harassment and discrimination. The case was eventually settled. Ex-Tinder employees Chris Gulczynski and Sarah Mick joined Herd to start Bumble more than three years ago. Gulczynski and Mick, who are designers, are at the center of the stolen secret allegations in the suit.The two had knowledge of an "undo" button talked about at Tinder, according to the complaint. That feature was "nearly, if not literally, identical" to Bumble's backtrack feature, the lawsuit says. The backtrack feature allows users to go back in time to "like" someone they may have accidentally passed on.Gulczynski and Mick also helped implement photo messaging at Bumble, something Gulczynski had allegedly mocked up a design for while at Tinder.In a statement, a Match Group spokesperson said the company is "committed to protecting the intellectual property and proprietary data that defines our business,"Bumble did not immediately respond to request for comment. According to the Linkedin accounts for Gulczynski and Mick, both have left Bumble. They did not immediately respond to messages seeking comment about the lawsuit.Axios was first to report that Match Group had filed the suit.It's been widely reported that Bumble once turned down a buyout offer from Match Group. Match Group was reportedly still interested in Bumble's business as recently as November of last year.Match Group said it doesn't comment on mergers and acquisitions speculation.In an interview with journalist Gayle King at the SXSW festival last week, Wolfe Herd declined to talk about any conversations — past or present — with Match Group, the parent company of Tinder. 3251

Today would be a normal drive to work for Amelia Caceres — except her house is surrounded by police tape. Adrian Perez helped her get out, both still in shock after hearing the brand new bridge outside their home collapsed."We were some of the first people on the front,” Caceres said. “And we saw the cars crushed underneath it was really horrifying, so it was really scary.”“My mind just does not captivate that that happened,” Perez said.Caceres and Perez saw the scene unfold, in disbelief. “It’s kind of like surreal,” Perez said. “Like it was a movie. There was a woman — I guess that she was trapped in the car like under the car .. she was crying hysterically. It was just really strange.”What made it even more strange for these two is that they had just watched the bridge go up days before.“It was just up. It was done,” Caceras said. “And it seemed almost like it was amazing that they had done it so quickly.”The bridge was designed to provide a safe way for students at Florida International University, like Perez, to cross a busy highway."I was really excited about this bridge because I was like finally I won’t have to go through the death trap that is eighth street crossing," Perez said. "Now, that’s kind of ironic."Carlos Devarona lives less than a mile away, and travels the street every day.“You have a blind faith in construction,” Devarona said. “You never think something like this is going to happen.”Watching the scene left him with even more questions, specifically why officials chose to perform a stress test in the moments before the collapse. “Not above live traffic  — you don’t do that,” Devarona said. “It just should never happen.”As investigators work to answer the many questions surrounding the collapse, Perez and Caceras, like so many others, wait for answers.“I’m sure that they did what was needed to get done,” Perez said. “I don’t think anyone would do something like this purposefully. Or negligently. I guess we will see.” 2034
