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

As calls for police reform permeate among supporters of the Black Lives Matter movement, the Fraternal Order of Police announced on Friday it has endorsed Donald Trump for president.The FOP, which is the nation’s largest police union with 355,000 members, endorsed Trump for the second time. The union has not endorsed a Democrat for president since 1996. The FOP endorsed George W. Bush in 2004 and 2004, John McCain in 2008, and did not issue a formal endorsement in 2012.“During his first four years, President Trump has made it crystal clear that he has our backs,” FOP President Patrick Yoes said. “Our members know that he listens to the concerns of our brothers and sisters in uniform and is able to make tough decisions on the issues most important to law enforcement. President Trump is committed to keeping our communities and families safe.”While Democratic nominee Joe Biden did not win over the support of the FOP, the Biden campaign responded on Friday by announcing it has garnered support from 190 law enforcement officials throughout the US.The list distributed by the Biden campaign includes current and former sheriffs, prosecutors and attorneys general.“Joe Biden has always stood on the right side of the law and is offering a much needed vision for our Nation. When asked the question, would you feel safe in Joe Biden’s America? The answer is yes,” said Retired Chief and former President of the Major Cities Chiefs Association, Tom Manger. “I’ve worked with Vice President Biden for years and know that he can heal the divide in our Country. He has condemned violence of all kinds, and there is no question that I would feel safe in Joe Biden’s America.”Previously, Yoes expressed his support for “Operation Legend,” a program launched by the White House to send federal agents to cities dealing with unrest following the death of George Floyd.“Law enforcement and the maintenance of public safety is primarily the responsibility of local governments,” Yoes explained. “But in too many of our cities, the violence has reached such levels that local agencies need additional resources. Our men and women in uniform in these jurisdictions are demoralized by anti-police rhetoric and they are exhausted from lengthy shifts in response to the pandemic. They desperately need the help that the President is going to provide.” 2353

An employee of a Virginia Publix grocery store who is deaf and lacks peripheral vision claimed she was assaulted by a customer after the employee said she could not hear the woman, WRIC-TV reported. Liberty Gratz was reportedly stocking a shelf when a woman trying to get Gratz's attention punched her from behind. The punch got Gratz's attention, and Gratz was able to point the woman in the right direction, but the incident left Gratz stunned. "She doesn't have that peripheral vision, so she's really focused on her work," Gratz's mom Jeanette Gratx told WRIC. "She doesn't always notice the people beside her."Liberty Gratz later had store management review video footage, but managers were unable to make out the woman. "She could still feel it when I picked her up from work," Jeanette Gratz told WRIC. "How would you feel if you were working and someone just came up behind you and decided to punch you?"Liberty Gratz told WRIC she wishes she could talk to the woman about being kind to people, whether they have a disability or not.  1110

An aspiring journalist and U.S. President, 9-year-old Arthur Brook has been spending much of his time in recent months interviewing WWII veterans to preserve their stories.

There aren't that many of them," said Brook.Along with his dad and sister Sofia, Arthur visits the Veterans Home of California, Chula Vista, to conduct interviews. "Well, most of them have never been interviewed before, never in their whole lives!" said Arthur.Arthur posts his interviews on his YouTube channel, Kids Discovering.When Arthur learned one of the residents, Edwin Schwimmer, would be turning 100 in September, he wanted to do something special for him.
