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

To know how a pandemic and politics have impacted Nogales, Arizona, Aissa Huerta will tell you to just look around.“It’s another world here, so often, it’s missed,” said Huerta.On the street that’s home to her art gallery, steps from the border, there’s not much to see at all. Morley Avenue is empty, many of the stores are closed.“We don’t have shoppers,” said business owner Evan Kory, who owns La Cinderella.For more than seven decades., Kory's family has owned stores in Nogales. The Arizona border city has a population of around 20,000 people. On the other side of the border wall is Nogales, Mexico, a city with a population of more than 200,000 people.Since March, the Mexican-American border has been closed to non-essential travel. The rules mean Mexican shoppers and the millions of dollars they spend in Arizona must stay on the other side of the wall.Kory says at least 90 percent of his store’s customers are from Mexico.“We’ve always been dependent on population in Mexico to support our local economy, so as soon as that’s cut off, our economy is shut down essentially,” he explained.Air travel isn’t restricted, but policy says people must have an essential reason to drive or walk across the border.For now, the restrictions that have been extended monthly since March, mean Alex La Pierre can’t lead tours across the border for his non-profit, the Border Community Alliance, a group that aims to show how concrete and barbed wire can’t divide two cities with powerful similarities.“The more opportunities that we can get to, citizen to citizen, one on one, to meet our neighbor and to see that we’re all not that scary that we have a lot of common interests,” La Pierre said.“The worst part is we can’t share what we love about this area,” said Chef Minerva Orduno Rincon, who has led tours with BCA, using food to create a connection across the border.In this part of Arizona, it’s less about what’s considered Mexican or American.“Really it feels like one whole city here, just divided by a fence,” said Nogales high schooler Ingrid Torres.Many of Torres’ friends live and Mexico and she hasn’t seen them since the pandemic began.For locals like Aissa Huerta, the closer you live to the border, the easier it can be to see through the narratives about immigration often written by those who live far away.“You hear about the worst-case scenario or the drug busts or immigration, so you hear the atrocities of this area without ever getting the opportunity for residents here to tell their story or what it's like to live on the border of two different nations,” Huerta said. 2604

Thousands of unwanted house guests left their mark on a Pennsylvania home. After recent heavy rains, a family noticed dark lines coming down the wall, and realized it was honey from a hidden beehive.Justin and Andrea Isabell told CNN they originally thought the drips in their mudroom were water damage after recent rains from Tropical Storm Fay. They live in Perkasie, between Allentown and Philadelphia."We've never heard any buzzing or anything," Andrea told CNN. "When we saw the stream coming down the wall, we just kind of worked our way up." 556
