According to a study published by UCLA's Anderson School of Management, the COVID-19 pandemic has put the U.S. economy into a "depression" and projects that the country's GDP won't return to pre-pandemic levels until early 2023.The study was published by David Shulman of UCLA's Anderson Forecast — a research firm at the school that publishes a quarterly outlook on the U.S. economy."Make no mistake, the public health crisis of the pandemic morphed into a depression-like crisis in the economy," Schulman wrote. "To call this crisis a recession is a misnomer."The report says that despite a drastic response from both the Trump Administration and the Federal Resevre, it will take years for both employment levels and GDP to return to were it was before COVID-19 reached America."Simply put, despite the Paycheck Protection Program too many small businesses will fail and millions of jobs in restaurants and personal service firms will disappear in the short-run," the report reads. "We believe that even with the availability of a vaccine it will take time for consumers to return to normal. (It took more than two years after 9/11 for air travel to return to its prior peak.) With businesses taking on a huge amount of debt, repayment of that debt will take a priority over new capital spending. And do not forget that state and local budgets suffered a revenue collapse that even with federal assistance it will take years to recover from."The U.S. lost 22 million non-farming jobs in the early months of the pandemic, the report says. The report does offer at least one bright spot: the housing market. The report mentions that despite high unemployment rates, "consumer demand remains strong" and that markets will return to pre-pandemic levels fairly soon.Finally, the report projects that the pandemic will accelerate some trends that were already in motion, particularly the growth of online retail, telecommuting and rising tensions between the U.S. and China. 1980

After making a go at in-person classes, a jump in COVID-19 cases on campus has prompted the University of North Carolina in Chapel Hill to shift to virtual only for all undergraduate courses, the university announced Monday.UNC will start distance learning on Wednesday.The university reported 129 confirmed COVID-19 cases last week, and a jump in its positivity rate from 2.8% to 13.6%. The university said it has tested 954 students with 177 in isolation and 349 in quarantine. The university said that most of the infected students have mild symptoms. The university said graduate, professional and health affairs schools will continue to be taught as they are, or as directed by the schools.UNC will allow students to cancel residence hall housing without penalty in an effort to depopulate the campus.“There are no easy answers as the nation navigates through the pandemic,” UNC President Peter Hans said. “At this point, we haven’t received any information that would lead to similar modifications at any of our other universities. Whether at Chapel Hill or another institution, students must continue to wear facial coverings and maintain social distancing, as their personal responsibility, particularly in off-campus settings, is critical to the success of this semester and to protect public health.”The university’s football team is still slated to play this fall, along with other members of the ACC. Two of the five “Power 5” conferences, the Pac-12 and Big 10, have opted to delay their seasons to the spring. The ACC, SEC and Big 12 are still slated to play this fall.The good news for the state of North Carolina is coronavirus cases are declining. According to New York Times data, the state was averaging 2,000 new cases per day, but that number has fallen to under 1,300. Deaths are still an issue in the Tar Heel state, with an average of 25 people dying per day from coronavirus-related illnesses. 1926

After her 15-year-old son ended up "in critical and life-threatening condition" from an adenovirus outbreak at a New Jersey health care facility, one mother is suing those who she believes allowed her son to end up in the ICU, according to a lawsuit filed Wednesday.Paula Costigan's son, William DelGrosso, was one of dozens of medically fragile children who were infected with the virus beginning in late September at the Wanaque Center for Nursing and Rehabilitation in Haskell, New Jersey.As of Friday, 31 residents have been affected by the outbreak, including 10 deaths, according to the state health department. DelGrosso remains hospitalized.According to the lawsuit, DelGrosso came down with a fever on October 11 and was transferred to the intensive care unit at Hackensack University Medical Center on October 18 with "serious respiratory complications." He is still there now, according to the family's lawyer, Paul da Costa."As a mother, it's hard enough to not have your child under your own roof and have to trust and rely on a facility to care for your child," da Costa said, adding that Costigan "feels as if the facility was trying to hide the fact there was this serious virus spreading like wildfire." 1228

After almost two years circling an ancient asteroid hundreds of millions of miles away, a NASA spacecraft this week will attempt to descend to the treacherous, boulder-packed surface and snatch a handful of rubble.The drama unfolds Tuesday as the U.S. takes its first crack at collecting asteroid samples for return to Earth, a feat accomplished so far only by Japan.Brimming with names inspired by Egyptian mythology, the Osiris-Rex mission is looking to bring back at least 2 ounces (60 grams) worth of asteroid Bennu, the biggest otherworldly haul from beyond the moon.The van-sized spacecraft is aiming for the relatively flat middle of a tennis court-sized crater named Nightingale — a spot comparable to a few parking places here on Earth. Boulders as big as buildings loom over the targeted touchdown zone.“So for some perspective, the next time you park your car in front of your house or in front of a coffee shop and walk inside, think about the challenge of navigating Osiris-Rex into one of these spots from 200 million miles away,” said NASA’s deputy project manager Mike Moreau.Once it drops out of its half-mile-high (0.75 kilometer-high) orbit around Bennu, the spacecraft will take a deliberate four hours to make it all the way down, to just above the surface.Then the action cranks up when Osiris-Rex’s 11-foot (3.4-meter) arm reaches out and touches Bennu. Contact should last five to 10 seconds, just long enough to shoot out pressurized nitrogen gas and suck up the churned dirt and gravel. Programmed in advance, the spacecraft will operate autonomously during the unprecedented touch-and-go maneuver. With an 18-minute lag in radio communication each way, ground controllers for spacecraft builder Lockheed Martin near Denver can’t intervene.If the first attempt doesn’t work, Osiris-Rex can try again. Any collected samples won’t reach Earth until 2023.While NASA has brought back comet dust and solar wind particles, it’s never attempted to sample one of the nearly 1 million known asteroids lurking in our solar system until now. Japan, meanwhile, expects to get samples from asteroid Ryugu in December — in the milligrams at most — 10 years after bringing back specks from asteroid Itokawa.Bennu is an asteroid picker’s paradise.The big, black, roundish, carbon-rich space rock — taller than New York’s Empire State Building — was around when our solar system was forming 4.5 billion years ago. Scientists consider it a time capsule full of pristine building blocks that could help explain how life formed on Earth and possibly elsewhere.“This is all about understanding our origins,” said the mission’s principal scientist, Dante Lauretta of the University of Arizona.There also are selfish reasons for getting to know Bennu better.The solar-orbiting asteroid, which swings by Earth every six years, could take aim at us late in the next century. NASA puts the odds of an impact at 1-in-2,700. The more scientists know about potentially menacing asteroids like Bennu, the safer Earth will be.When Osiris-Rex blasted off in 2016 on the more than 0 million mission, scientists envisioned sandy stretches at Bennu. So the spacecraft was designed to ingest small pebbles less than an inch (2 centimeters) across.Scientists were stunned to find massive rocks and chunky gravel all over the place when the spacecraft arrived in 2018. And pebbles were occasionally seen shooting off the asteroid, falling back and sometimes ricocheting off again in a cosmic game of ping-pong.With so much rough terrain, engineers scrambled to aim for a tighter spot than originally anticipated. Nightingale Crater, the prime target, appears to have the biggest abundance of fine grains, but boulders still abound, including one dubbed Mount Doom.Then COVID-19 struck.The team fell behind and bumped the second and final touch-and-go dress rehearsal for the spacecraft to August. That pushed the sample grab to October.“Returning a sample is hard,” said NASA’s science mission chief, Thomas Zurbuchen. “The COVID made it even harder.”Osiris-Rex has three bottles of nitrogen gas, which means it can touch down three times — no more.The spacecraft automatically will back away if it encounters unexpected hazards like big rocks that could cause it to tip over. And there’s a chance it will touch down safely, but fail to collect enough rubble.In either case, the spacecraft would return to orbit around Bennu and try again in January at another location.With the first try finally here, Lauretta is worried, nervous, excited “and confident we have done everything possible to ensure a safe sampling.”___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

About 20,000 residents are under mandatory evacuation orders as a Southern California fire -- which authorities say was set intentionally -- spread this week.The Holy Fire started Monday in the Cleveland National Forest and has so far destroyed 12 structures, according to fire authorities.A man has been arrested in connection with the fire that is wreaking havoc near the border between Orange and Riverside counties, which are among the most populous counties in California.The Holy Fire has burned 6,200 acres and is 5% contained.Although it's not the largest fire burning in the state, there are growing concerns about how it could affect residential communities -- including Lake Elsinore. Some small communities in Riverside County are under mandatory evacuation orders affecting about 7,000 residential structures, according to authorities.Forrest Gordon Clark, 51, was being held at the Orange County Jail on Wednesday on suspicion of two counts of felony arson, a count of felony threat to terrorize and misdemeanor resisting arrest, the Cleveland National Forest said via Twitter.He is being held on million bail and expected in court on Thursday.The charges being leveled could carry a life sentence, said Susan Schroeder of the Orange County District Attorney's Office."Arson is a terrible crime that destroys dreams," she said in a press conference Wednesday.Witness statements, physical evidence and fire burn patterns connected the man to the fire, said Shane Sherwood with the Orange County Fire Authority.Volunteer Fire Chief Mike Milligan told the Orange County Register that Clark was screaming in the community and sent an email that said "this place will burn" last week.Before he was arrested, Clark told a cameraman he was asleep when the fire started and had no idea how it began."Who would go out with low humidity, and high wind and highest heat temperatures this time of year and intentionally set the forest on fire?" asked Orange County Supervisor Todd Spitzer during Wednesday's press conference.An excessive heat warning for the fire area has been issued with temperatures higher than 100 degrees."We know this district burns, but it should never burn because of an intentional act," Spitzer said. "This shouldn't be called the Holy Jim Fire, this should be called the Holy Hell Fire."Spitzer added that his constituents are "scared" and "fleeing their homes.""They're leaving property behind, they're putting everything they can in the back of their cars as quickly as possible."Fire officials warned residents to heed evacuation orders."Even if you're miles way, you want to be prepared if you're near the fire area or in an environment that can burn," said Thanh Nguyen with the SoCal Team One Fire Management Team, who suggested having a packed bag ready to go.  2814
