Dybwad, based in Salt Lake City, started the company as a side project in 2015 because he wanted to better understand the pollution in his own neighborhood, where he could see dust blowing from a gravel mine nearly every day. He experimented with various sensors and settled on a type that uses lasers to measure particles in the air.

Even in Rhode Island, while the majority of schools have a registered nurse, a few districts lean on a single school nurse for multiple schools. … [Read more...] about Can your school open while avoiding a COVID-19 outbreak?

Now, having been away from work for months, she’s concerned by the many unknowns. “The mail processing machines, I hope they haven’t pulled [them] out,” she says, of the processing facility in downtown L.A. She hasn’t heard of any local mailboxes being removed, but hasn’t been there to see for herself. “This is really kind of a shock,” she says. “I don’t know how this is all going to pan out.” Merrick takes her federal responsibility seriously.
