Decades of underinvestment has left tens of thousands of schools across the country with inadequate ventilation systems, a problem that is now front and center in the debate to reopen schools during the pandemic.Nationally, 90 percent of schools fail to meet minimum ventilation standards. It’s an issue Dr. Joseph Allen has been sounding the alarm about since COVID-19 first shut down schools earlier this year.“We’ve chronically underinvested in our schools’ buildings,” said Dr. Allen who serves as the director of the Healthy Buildings program at the Harvard Chan School of Public Health.Dr. Allen and his colleagues have spent months analyzing school buildings, and back in June, they released a detailed 60-page report that school districts could follow in order to safely bring kids back into the classroom.In order to keep COVID-19 from spreading in schools, two things have to happen: everyone in the buildings must be wearing masks and school districts need to ensure buildings have proper ventilation, the report found.“If air is being recirculated and not filtered, all of that air that’s coming from one space and going to another could be potentially contaminated and spread the virus,” Dr. Allen said.But replacing decades-old ventilation systems that may not work properly is expensive and time-consuming. Because of that, Dr. Allen is recommending school districts also consider portable air cleaners for classrooms.Through his research, Dr. Allen found that if you can change the air in a classroom five times per hour, it cleans the air in that space every 12 minutes. However, the air cleaners must be equipped with a HEPPA filter in order to be effective.Even something as simple as opening windows could reduce the transmission of the virus.“If you look at the cases of spread in school right now, they all share common traits; it’s no mask-wearing and low to no ventilation. When we do that, we can guarantee there will be more cases,” he explained.Last week, the Healthy Buildings program also released a detailed portable air cleaner calculator. The tool allows school administrators to input the size of the classroom, even ceiling height, and then determine the kind of air cleaner that would most effectively keep COVID-19 from spreading.“It is critically important that we get kids back into in-person learning and we haven’t treated it as this national priority that it needs to be,” Dr. Allen added. 2438

DENVER – Coloradans who don’t identify as simply male or female will soon be able to choose a third sex option on their driver’s license or identification card.The Colorado Department of Revenue announced that residents will have three options – M (male), F (female) and X – starting this month.The change in policy is to bring the state into better compliance following two court rulings at the state and federal level, the Division of Motor Vehicles’ Executive Director Michael Hartman told the Denver Post.“This is an important step for the state of Colorado that the state documents reflect our values,” Hartman told the Post. “People are people no matter their sex identification.”Hartman said the change will be a simple one and won’t cost taxpayers any money.In order to choose “X” for their sex on a driver’s license, a person will need to provide either a change of sex designation form signed by a licensed medical or behavioral health care provider or a birth certificate with an “X” sex designation. The change cannot be made online.California, Oregon, Minnesota, Maine and Washington, DC already offer a non-binary sex designation on driver’s licenses and ID cards. Licenses from those states with an “X” designation can be converted directly to a Colorado license with the “X” sex marker.The state said a license or ID card with the "X" designation will be compliant with the federal REAL ID standards.The state also is proposing allowing a third sex option on birth certificates following the settlement of a lawsuit that aimed to declare the state’s birth certificate policy unconstitutional because of its requirement that a person’s sex be surgically changed in order to alter the sex designation on a certificate.The new driver’s license and ID card policy goes into effect under an emergency rule on Nov. 30. The state will then begin the process to make the policy permanent. That process will allow for public comment. 1953

Demonstrators in Sacramento marched for hours Friday through California's capital and called for justice in the contentious police shooting death of Stephon Clark, an unarmed black man.During a second day of protests, activists marched about a mile from the city's Tower Bridge to the steps of state Capitol building.They chanted "Black lives matter" and called out Clark's name. One of the march leaders told people to hold up their cellphones; police have said Clark had an object in his hand, but no weapon was found."It's just a cellphone," the man yelled out. "I don't know how the hell it looks like a gun to anybody else." 637

DANE COUNTY, Wisc. — A Whitefish Bay boy who underwent heart surgery, and a piglet that jumped out of a moving truck. These two completely different events would serendipitously come together to inspire our community, which is why it is Positively Milwaukee.It has been a long journey for six-year-old Tristan Zick and “Maxwell the Pig.” They met for the first time at Heartland Farm Sanctuary, just outside Madison.To say Tristan is a fan of pigs would be an understatement.“Pigs are my favorite animal," Tristan squealed. "I love piggies!”Maxwell made it to the sanctuary after leaping out of a truck to his freedom. He is now all healed from his wounds.This is something Tristan can relate to. He had heart surgery nine months ago, and so did his stuffed pig.His mom Stacy adds, “What was wonderful was that he was able to take care of the little pig, and I think that alleviated his pain because he was looking after his little stuffed pig. It was so cute!”When Tristan’s birthday rolled around this year, they came across Maxwell’s story. In lieu of gifts, the family raised money to help the piggy recover. The family even hosted a drive-thru bake sale, where the family baked pig-shaped cookies.Stacy shares what blew her away most of all, “[The sanctuary worker] asked what Tristan’s birthday was, and I told him. They said that was the same day Maxwell jumped out of his truck!”After the journey they have both been on, it already seems like they are bonded for life.Click here to learn more about the Heartland Sanctuary in Verona, Wisconsin.This story was first reported by Julia Fello at TMJ4 in Milwaukee, Wisconsin. 1637
