The pandemic has added extra stress to our lives, but that's not stopping some of us from getting more sleep.New research from the University of Colorado Boulder and the University of Washington looked at how stay-at-home orders and social distancing guidelines have impacted college students' sleeping habits.They found that on average, students have been sleeping 30 minutes more per weekday and 24 minutes more per weekend day. They've also been keeping more consistent sleep schedules.This is similar to what a study of people ages 18 to 65 in Europe found during this same time.So, the big question now is whether these habits will continue now that stay at home orders are lifted.“One of the things we recognize is that when people who weren't getting enough sleep start to actually get better sleep because they can and they realize ‘wow that makes a difference in my life,’ a number of people choose behaviorally to go ahead and continue to get that better sleep,” said Ken Wright, integrative physiology professor at CU Boulder.As for the question about whether the quality of our sleep has improved, the study in Europe did look at that. It found on average, people have been seeing slight reductions in the quality of their sleep, but there are things you can do to help with this.“When they looked at the group as a whole, they found that those people who got exercise and got more sunlight during the COVID stay-at-home, they found that they actually had less reductions in their sleep quality,” said Wright.One negative result of the stay-at-home orders on our sleep in both studies – people have been going to bed later, both during the week and on weekends. Researchers say it will probably be healthier for us if we can start going to bed earlier now. 1776

The Justice Department has dropped its case against a woman who laughed out loud during the confirmation hearing for Attorney General Jeff Sessions, ending months of legal wrangling.The woman, Desiree Fairooz, was protesting with Code Pink, a progressive group whose activists are regularly seen around Washington. She was arrested by a Capitol Police officer after audibly laughing during Sessions' confirmation hearing in January.But prosecutors filed a "nolle prosequi," or notice that it would no longer pursue charges, with the DC Superior Court on Monday.She had been prosecuted by the DC US Attorney's Office and had been convicted of a misdemeanor before a judge threw out the conviction in July and ordered a new trial. The government had decided to retry the case after Fairooz rejected a plea deal, and a trial date had been set for next week.Fairooz tweeted the notice was a "relief" Monday night."Just received this, "Governments Notice of Nolle Prosequi" What a relief! Guess they've got enough "laughing" matters to deal with!" she tweeted.The US Attorney's Office declined to explain what had changed."The US Attorney's Office for the District of Columbia yesterday filed a notice dismissing the case involving Desiree Ali-Fairooz," said spokesman Bill Miller. "The US Attorney's Office typically does not discuss charging decisions, and has no comment on the decision to dismiss this particular case."The original arrest happened after Fairooz laughed after Alabama Republican Sen. Richard Shelby told senators at Sessions' confirmation hearing that his former colleague had a record of "treating all Americans equally under the law."Her laughter lasted a few seconds and Shelby continued with his speech without acknowledging the disturbance.Fairooz's attorney said in a statement his client is "relieved and happy" about the result."Yesterday the government dismissed the case for reasons I can only speculate about. And which I may never fully know (though I have various theories)," Samuel Bogash said in an email. "Though as her lawyer I would have preferred a 'not guilty' at the first trial, I'm happy for Ms. Fairooz." 2156

The news of Sen. John McCain's passing has led to many questions over what happens to the lawmaker's Senate seat.The Seventeenth Amendment, which established the direct election of senators, also clarifies rules of filling seats left vacant due to a senator's death, resignation, or expulsion.The amendment allows state legislatures to empower the governor to appoint a replacement to fulfill the term, which means Gov. Doug Ducey's selection will serve until our next general election in November 2020.In Arizona's case, as with a handful of other states, the governor's appointee must be of the same political party as that of the vacating senator, meaning Ducey will fill the spot with a fellow Republican.A Friday report from the New York Times said Rep. Martha McSally and McCain's wife, Cindy, could be potential picks for Ducey to fill the open seat. 890

The jarring noises and machines inside the Usheco plastics warehouse sound like home to the Schaeffer family.“My grandfather, Bernarr Schaeffer, started the business in ’61. So, proud to be third generation,” said Alethea Shuman, who will one day take over the company for her father.The company started with the World War II fighter pilot, and now, more than 60 years later, nearly every member of his family has worked inside these four walls.“It’s like having your own team. There’s an extra level of trust that you just don’t get elsewhere,” said Wayne Schaeffer, Bernarr’s son and the President of Usheco.They build all kinds of plastic devices. The company is known for air purifying planters, handicapped equipment, and laboratory supplies.“Our business was really founded on my grandfather wanting to make health-related products,” said Shuman. Now, this family is seeing a huge boom in some new products.At the start of the pandemic when everything shut down, Usheco had to lay off much of their staff because business dropped by about 40 percent. However, they designed face shields and desk barriers and had to bring everyone back on and hire extra workers on just to fulfill all their orders.“We only cut everyone’s hours for one week," said Shuman. "The following week, we were back to full-time hours for everyone."Hundreds of thousands of face shields and plastic desk barriers in custom shapes and sizes are coming out of this factory.While most businesses are in need of help themselves, the plastics industry is one of few seeing pandemic profits.“Things are looking pretty good for us,” said Schaeffer. “How can you not be thrilled to be helping out and making your business grow?”The Schaeffers say their U.S. made products are growing to a global scale. “Our pricing is similar to China now,” said Wayne.“We’re seeing new quotes coming in for things that are typically done overseas and were grateful to be able to help with that,” said Shuman.Shuman said by the time she takes over the business, she hopes the products keeping her grandfather’s legacy alive are no longer in stock.“I’m hoping we figure out a way to get past this and we’re not going to need PPE and sneeze guards, and the business coming back to the U.S. is going to support us. And from what I can see, that’s happening,” she said.But more important than business, is carrying on a tradition.“Over the last few months, we really have understood where our roots are and where we’re going,” she said.Towards a future where simple, plastic products mean more than ever before. 2571

The Pennsylvania Academy of the Arts, or PAFA, is the nation’s oldest art school and museum but it’s facing a new dilemma: what to do with an artist’s work when the artist is accused of sexual misconduct.                                                                                                                                                                       The artist in question is portraitist Chuck Close. He may not be a household name to you and I, but in the art community he’s huge. He’s considered a pioneer of portrait work who rose to prominence in the 1960s who made a name for himself in the way he incorporated photography within the world of painting.But this past December, four female models accused the artist of sexual harassment, claims the Close denied in an interview with the New York Times. Close, through a rep, declined our request comment.Brooke Davis Anderson, PAFA’s museum director, had a tough call to make: what to do with a high-profile exhibit, on view in one of their most prominent galleries, filled with Close’s work.“I’m very hesitant to censor artwork,” Anderson said. She and the museum executive leadership convened their art community of students, staff, and patrons to gauge the reactions to try to fiigure out ho to handle the exhibit.“We really asked everybody what they were feeling, thinking, how they were responding,” Anderson said. “How they felt we should respond as an institution, and collectively what this meant for us.”The broader discussion is not all that new. You may recall that a few years back, “The Cosby Show” was pulled from syndication following allegations made by a slew of women against its star and creator Bill Cosby. It’s since made a slow re-emergence on small cable networks.In the past year, we’ve had to ask ourselves whether we as a society are comfortable enjoying re-runs of “Louie” on FX in the wake of comedian Louis C.K.’s admitted mistreatment of women. Or what about previous seasons of “House of Cards” now that allegations regarding Kevin Spacey have come to light?Even Pablo Picasso was known to have mistreated the opposite sex.The obvious question becomes: can an artist’s work be separated completely form the artist and their personal decisions?[,We asked Melissa Joseph and Candace Jensen, both students at PAFA who took part in the museum’s forum on what to do with the Close exhibit. “That’s like the zinger question!” Jensen said, through laughter.“Many students did want the [Chuck Close] show to come down,” Joseph added. “You just want it to go away, you know? You don’t want to have to look at it anymore.”But, she says, over a few weeks’ time her views evolved.“If you think about what’s going to be most productive for this movement, what’s going to actually move things forward, your initial emotional reaction isn’t always the right one.”Jensen interjected.“Well yeah but don’t diminish emotional responses. Emotional responses are really tied up with moral responses,” Jensen said, adding that understanding the context in which art was made is key.“Being willing to value the aesthetic decisions that were made and also be critical of the maker,” Jensen said. “So it’s not a black and white.”PAFA is not the only institution having to navigate this gray area.Seattle University recently removed a Chuck Close self-portrait hanging in a campus library.The National Gallery of Art in Washington, DC indefinitely postponed its Chuck Close exhibit that was set to open in May. A museum spokesperson declined an interview but told us in an email that “all parties involved” agreed that it was “not the appropriate time” to present the installation. Anderson made the final call for PAFA: keep the Close exhibit, but with a caveat in the adjoining gallery right next door.“The site of an exhibition isn’t where you respond by censorship or changing the project. I rather felt that what we could do because of our real estate here. We had an opportunity to have a dialogue with another project.”That other project is what they’re calling a “response exhibit,” a gallery created to force a conversation that explores gender and equality in the art community.“There are no longer town halls and town squares,” Anderson said. “So what if a museum was a site where we could say we don’t agree, and lets unpack how we don’t agree. And let’s understand how we don’t agree, and maybe that advances us a little bit.”Anderson pointed out some of the highlights of the responsive exhibit, including a timeline regarding how and when the art world can become “an equitable space.”“How do we get more women in leadership positions? Women artists and collections, people of color, trans people, how do we create that balance?” 5181
