A teacher at Dickson Intermediate School in Tennessee launched an emergency lunch money fund for students after an interaction with one child inspired her to help children in need."As I was walking through the cafeteria one day, I saw a child with no tray and no drink just stopped to build those relationships as teacher do, and just asked are you not eating? Do you need something?" said sixth grade literary teacher Julie Potter. "His comment was mom said we’re out of money so I can’t eat today."Potter told the student to grab lunch, on her.But she said she realized that was a short term solution."I thought if I could just donate just a few dollars to set up an account so the next time, the next child will feel safe enough to go through the line without worrying about pride and be fed," Potter said.So Potter put out a post on Facebook, detailing her interaction with the student and a plan to help others."I share this message to say I would like to set up a special lunch account called 1 in 4," the post read. "This account would be for those students, just a handful and only as needed, we see going without food. An account where we as school staff could quietly say, 'Go through the line and it will be taken care of.'"In just 10 days, teachers and parents have donated to the fund and two students have used the emergency money to eat.And while Dickson Intermediate never turns away a hungry student, officials said this helps further break down barriers."Some are going to feel a little embarrassed or shy about asking for help," said School Nutrition Supervisor Jason Collins. "That’s why I think it’s so important that we focus on building those relationships."According to Feed America about one in four children in Dickson County are food insecure but don't qualify for federal assistance.If you'd like to donate to Dickson Intermediate's fund you can drop money off at the school's front office or mail it to the school. Please specify that your donation is for the 1 in 4 lunch account. 2063

A recent study published Tuesday in the journal JAMA Internal Medicine found that most Americans are still susceptible to COVID-19.According to the study, researchers studied the blood samples of 177,919 Americans across the nation, D.C., and Puerto Rico between July 27 and Sept. 24. They found that fewer than 10% of the people had detectable COVID antibodies."In this U.S. nationwide seroprevalence cross-sectional study, we found that as of September 2020, most persons in the US did not have detectable SARS-CoV-2 antibodies, and seroprevalence estimates varied widely by jurisdiction," the authors concluded. "Continued biweekly testing of sera collected by commercial laboratories will allow for assessment of the changing epidemiology of SARS-CoV-2 in the U.S. in the coming months. Our results reinforce the need for continued public health preventive measures, including the use of face masks and social distancing, to limit the spread of SARS-CoV-2 in the U.S."Researchers noted that Seroprevalence varied between metropolitan/nonmetropolitan areas and across regions, with estimates as high as 23% in the northeast, 13% in the south, and forecasts in the midwest and west were less than 10%.The researchers also found that Seroprevalence was often lowest in older age groups. 1295

  

A new study has found that those who drink moderate amounts of alcohol or coffee lived longer than those who didn’t, reports the Chicago Tribune.The research was led by University of California neurologist Claudia Kawas who tracked 1,700 nonagenarians enrolled in the 90+ study, which began in 2003.According to researchers, those who drank roughly two glasses of beer or wine a day were 18 percent less likely to experience premature death.The findings mean that, according to the research, drinking alcohol increased longevity more than exercise.The study found that participants who exercised 15 to 45 minutes a day cut their risk of early death by 11 percent.And good news for coffee lovers. Participants who drank two cups of coffee a day also increased longevity by 10 percent.The study also found that people who were overweight in their 70s lived longer than normal or underweight people. 904

  

A Russian who allegedly worked on funding online propaganda efforts to manipulate voters in the 2016 and 2018 elections was charged with a federal crime Friday as part of a wider conspiracy to hurt American democracy.Elena Alekseevna Khusyaynova, 44, of St. Petersburg, Russia, is charged with conspiracy to defraud the United States for managing the financing of the social media troll operation that included the Internet Research Agency, which special counsel Robert Mueller's investigators charged with crimes earlier this year.Prosecutors who unsealed the complaint Friday say she aided the Russian effort to "inflame passions" online related to immigration, gun control and the Second Amendment, the Confederate flag, race relations, LGBT issues, the Women's March and the NFL National Anthem debate from December 2016 until May 2018.The social media efforts specifically focused on the shootings of church members in Charleston, South Carolina, and concert attendees in Las Vegas, Nevada, the Charlottesville "Unite the Right" rally, which left one counterprotester dead, and police shootings of African-American men, the complaint says.The criminal charge says the Russians' online manipulation effort focused on multiple political viewpoints and candidates, but frequently zeroed in on the Republican Party's most well-known leaders.In one effort to spread an online news article about the late Sen. John McCain's position on a border wall to stop illegal immigration, an alleged conspirator directed others to "brand McCain as an old geezer." They also attempted to paint House Speaker Paul Ryan as "a complete and absolute nobody incapable of any decisiveness" and as a "two-faced loudmouth."They aimed other efforts at stories about Jeb Bush, Sen. Marco Rubio and Senate Majority Leader Mitch McConnell, pushed to "fully support" Donald Trump, and called Mueller "a puppet of the establishment," according to the complaint.  1959
