Toilet paper, cleaning products, meat, and now possibly pepperoni. One of America’s favorite pizza toppings could become scarce due to the coronavirus pandemic.Pepperoni is becoming more expensive due to production slowdowns at meat plants and the high demand for pizza.Small pizza shops say pepperoni is now a pound — up from earlier this year, Bloomberg reported.Larger pizza chains have pre-negotiated contracts, so they haven’t been hit by the price increases or shortages just yet.This story was first reported by Lauren Cook at WPIX. 553

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

This undated image released by the Alabama Department of Archives and History shows Alabama's 1901 Constitution, which was intended to maintain white supremacy in the state. With the nation focused on racial justice because of the police killings of George Floyd and other Black people, state voters are being asked to remove racist phrases from the document once and for all. While no organized opposition has emerged, some worry that a conservative backlash against protests over racial injustice could harm the chances for passage.

Traveling by plane isn’t always comfortable. Often times it can be cramped, or the temperature isn’t right, or you’re sitting in a noisy area.But if you’re traveling this holiday season, keep in mind there are places to sit on the plane that are more optimal than other seats, says a flight attendant.Best place to sit if you’re always cold:If you hate being cold on a flight, do not sit next to the emergency exit windows. The outside air seeps in the most in those seats.   Best place to sit if you hate loud noise:Planes are notoriously loud, but if you need more of a quiet seat, chose one that's away from the kitchen, where the flight attendants work most.  Best place to sit if you want a lot of leg room:I think we’re all guilty of propping our feet up on the seat in front of us, because we're cramped. So, if you want a lot of leg room, chose the bulkhead seats, the seats right after the cabin divider or the emergency exit window seats.    Best place to sit if you hate turbulence:Turbulence on a flight is never fun, and if you get anxious, sit closer to the front of the plane. That way you won't feel the bumpiness as much as you would in the back. Depending on the flight experience you're looking for, a great website to check out before booking your next flight is called Seat Guru, where you can browse seat maps to over 1,100 aircrafts.  1405

Thursday morning Baltimore Police continue to search for the person who shot a Baltimore City Homicide Detective. ATF, the FBI, and Metro Crime Stoppers are offering a ,000 reward for information leading to an arrest and conviction of whoever pulled the trigger.RELATED: Officer down: Police-involved shooting in West BaltimoreRight now, police don't have much of a description of the shooter, so they're hoping witnesses will come forward and help them identify the gunman. Officers have cordoned off a huge area around the shooting scene, they are going door to door, and they're searching every alley in the area.  655
