As health experts warn about rising coronavirus cases from spread at indoor gatherings, a new website backed by recent research is trying to help people understand just how many people in what size space is risky for infection. Which could come in handy as some people consider small holiday gatherings.It’s more risky to be in a small room compared to a large gym. If people are calm and quiet, it is safer than singing or exercising no matter how distant they are.Given these types of scenarios, and the “rapidly advancing science” of how COVID-19 droplets behave, scientists at the Massachusetts Institute of Technology created the COVID-19 Indoor Safety Guideline application.Here’s an example:An average suburban house that is 2,000 square feet, with 25 people inside wearing cotton masks and talking in a whisper, can reduce their risk of transmission by only staying inside for 4 hours.If those same 25 people, in the same house, are not wearing a mask and are talking normally, the length of time to reduce transmission drops to just 50 minutes.And if those 25 people, in the same house, are singing along to Christmas music, without masks on, that time to safely reduce COVID-19 transmission indoors drops even further to just 8 minutes.If the size of the gathering is only 5 people, and there is still singing, no mask wearing, and it’s still a 2,000 square foot house, it becomes unsafe after just 27 minutes.The MIT website offers users the ability to select room size, number of people and length of time, then using previous research and scientific knowledge of airborne viruses, it predicts the risk of the indoor event. Users can change elements of the situation, like room size, mask wearing, ventilation, etc.Click here to visit the Indoor Safety Guideline website.In a restaurant, to reduce transmission, 50 people without masks and talking normally should stay for only two hours. If the restaurant has 100 people, to reduce transmission risk, they should only remain inside for 64 minutes.The researchers note current general social distancing guidelines (remain 6 feet apart) suggest 138 people would reduce their risk in the same size of space for an indefinite amount of time.Another example, a Boeing 737, the researchers’ model predicts 100 people can be onboard a 737 wearing masks and still reduce their risk of transmission by staying onboard less than 6 hours.The CDC updated their guidance about COVID-19 this fall, acknowledging ongoing research that shows coronavirus droplets “can remain suspended for many minutes to hours (in the air) and travel far from the source on air currents.”The Centers for Disease Control and Prevention also says coronavirus droplets can remain even when an infected person has left the room and can travel farther than six feet. 2800

An attorney for the former school resource officer at Marjory Stoneman Douglas High School defended the officer's response to the Parkland shooting, saying in a statement Monday that Scot Peterson acted appropriately during the shooting."Let there be no mistake, Mr. Peterson wishes that he could have prevented the untimely passing of the seventeen victims on that day, and his heart goes out to the families of the victims in their time of need," the statement from attorney Joseph DiRuzzo III says."However, the allegations that Mr. Peterson was a coward and that his performance, under the circumstances, failed to meet the standards of police officers are patently untrue."Peterson resigned on Thursday after Broward County Sheriff Scott Israel suspended Peterson without pay for allegedly waiting outside the Florida school as the shooting unfolded."What I saw was a deputy arrive at the west side of building 12, take up a position," Israel said of the footage. "And he never went in."But, in a statement, DiRuzzo said that Israel's statement "is, at best, gross over-simplification" of what happened when a shooter killed 17 people at the Florida school.Peterson initially ran toward the 1200 building where the shooting took place, and then he "heard gunshots but believed that those gunshots were originating from outside of any of the buildings on the school campus," according to DiRuzzo.The Broward County Sheriff's Office, or BSO, "trains its officers that in the event of outdoor gunfire one is to seek cover and assess the situation in order to communicate what one observes to other law enforcement," DiRuzzo said.Peterson acted consistent with his training and "took up a tactical position between the 700-800 buildings corridor/corner," Peterson said. He was the first officer to advise dispatch that he heard shots fired, and he initiated a "Code Red" to lock down the campus, according to the statement."Radio transmissions indicated that there was a gunshot victim in the area of the football field," which served to confirm Mr. Peterson's belief "that the shooter, or shooters, were outside," according to DiRuzzo's statement.Trump says Peterson 'choked' 2185

ANDERSON, South Carolina — We all remember that feeling of euphoria as kids, you wake up on a cold, snowy morning and hear those two magical words, "snow day!"  Well, it looks like that will soon become a thing of the past in one school district.Pause for the gasps of horror, yes, a school district in South Carolina is ditching snow days. Instead, the district will require students to do classwork online instead of watching television reruns or indulging in a Netflix binge.Last week, Anderson School District Five announced on Facebook it was selected to pilot the first eLearning program in the state of South Carolina.Here's how it works: When nasty weather strikes, these students will need to review assignments using their school-issued Chromebooks, which don't require internet access. The assignments will be uploaded via Google Classroom.Students who are having difficulty accessing those assignments or who are too young to have a Chromebook will be given a five-day grace period. 1037

An autopsy to determine when and how 20-year-old Iowa student Mollie Tibbetts died is planned for today.Tibbetts vanished while on an evening jog on July 18. Nearly a month later, a man who confessed to pursuing her as she ran on a country road led authorities to the field where a body believed to be hers was buried under corn stalks, officials said Tuesday.While authorities have yet to confirm the body is hers, they arrested Cristhian Bahena Rivera, 24, on first-degree murder charges.Rivera, who's an undocumented immigrant, told investigators he saw her and got out of his car. He ran beside Tibbetts -- even after she warned him she would call police, officials told reporters Tuesday. 701
