TORONTO (AP) — The United States has agreed with Canada and Mexico to extend their agreement to keep their border closed to non-essential travel to July 21 during the coronavirus pandemic. Canadian Prime Minister Justin Trudeau said Tuesday's agreement extends the closure by another 30 days. "This is an important decision that will keep people in both of our countries safe,” the prime minister said in his daily press conference. Americans who are returning to the U.S. and Canadians who are returning to Canada are exempted from the border closure.Acting Department of Homeland Security Secretary Chad Wolf issued a statement Tuesday on why extending non-essential travel restrictions with Canada and Mexico was necessary. "The Department of Homeland Security will ensure that the measures taken at our borders will protect America from all threats, including threats against the health and safety of our citizens," Wolf said in the statement. "Based on the success of the existing restrictions and the emergence of additional global COVID-19 hotspots, the Department will continue to limit non-essential travel at our land ports of entry with Canada and Mexico. This extension protects Americans while keeping essential trade and travel flowing as we reopen the American economy. The Department of Homeland Security is in close contact with our Canadian and Mexican counterparts regarding this extension, and they agree on the need to extend their non-essential travel restrictions as well. I look forward to continuing to work with our neighbors to maintain essential trade and travel while protecting the health of our respective citizenry." The Mexican Embassy in the United States said in a series of tweets that the decision came "after reviewing the development of the spread of COVID-19 in both countries." 1829

The U.S. Department of Agriculture announced on Thursday that it is looking for ways to transition some people off of the department's Supplemental Nutrition Assistance Program (SNAP).Specifically, the USDA is looking at beneficiaries who are not disabled and who don't have any dependents.“Long-term dependency has never been part of the American dream,” said U.S. Agriculture Secretary Sonny Perdue. “USDA’s goal is to move individuals and families from SNAP back to the workforce as the best long-term solution to poverty. Everyone who receives SNAP deserves an opportunity to become self-sufficient and build a productive, independent life.”Related:?Trump administration proposes Blue Apron-style overhaul for food stamps 773

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 were more than 35,600 requests from 28,200 public school teachers in every state on the crowdfunding website DonorsChoose.org — until now.The website that allows folks to seek donations to fund projects announced a company called Ripple, a global network that supports digital money transactions, donated million to fund every classroom project request on the crowdfunding platform.The gift represents the largest donation received by DonorsChoose.org in its 18-year history, according to a news release. "Ripple and its executives contributed the donation in XRP, which was converted to U.S. dollars and used to purchase the classroom materials," the release said."The Ripple team's donation provides the ultimate culmination of #BestSchoolDay, a campaign launched in March 2016 when 58 athletes, artists, entrepreneurs and philanthropists funded classroom requests in cities and states covering just under half of the country," the release said. "For a limited time, as teachers generate new classroom project requests on the site, DonorsChoose.org will offer donors the option of giving to the #BestSchoolDay Fund, which will be used to support projects from teachers creating their first requests on the site."DonorsChoose.org estimates that teachers will submit at least another 135,000 classroom project requests between now and the start of the next school year," the release states.  1434

Travelers heading to the Caribbean, Latin America, or Hawaii on American Airlines will now have the opportunity to participate in its COVID-19 pre-flight testing program."Our initial pre-flight testing has performed remarkably well, including terrific customer feedback about the ease and availability of testing options," said Robert Isom, President of American Airlines said in a press release on Monday. "This next phase is an invigorating step forward in American's relentless pursuit of reopening international travel and driving industry recovery while delivering a safe and positive travel experience."Beginning Nov. 16, passengers traveling from Miami, Florida, to Belize, Grenada, and St. Lucia will be offered pre-flight COVID-19 testing with a convenient at-home testing option.American stated travelers to each country will have three options when it comes to testing using an at-home test from LetsGetChecked:Belize: Travelers over the age of 6 must complete testing within 72 hours of departure.Grenada: Passengers must complete testing within seven days before their departure date.St. Lucia: Anyone over the age of 5 must complete testing within seven days of departure."Customers cannot board flights to St. Lucia without presenting a negative test result. Pre-arrival registration is mandatory; customers should visit stlucia.org for the latest information on travel restrictions and quarantine requirements," American stated.American said travelers could expect results within an average of 48 hours.Starting Monday, American said customers traveling from Chicago, Los Angeles, and Phoenix will now be able to use LetsGetChecked at-home tests.Travelers must complete their testing within 72 hours of the final leg of their departure, American stated.Customers should expect results within 48 hours."As of this announcement, travelers who present a negative test upon arrival will be exempt from the state's 14-day quarantine," American said. 1968
