RANCHO CORDOVA, Calif. (AP) — Gov. Gavin Newsom says he wants a Southern California county to reimpose stay-home orders amid a surge in positive coronavirus tests there and through much of the state. Imperial County, with a population of 175,000 people on the state’s border with Mexico, has been the slowest in the state to reopen. "Some counties, like Imperial, haven't been able to move into that attestation process, because they can't meet that criteria," Newsom said of the county's struggle to reopen. "We reserve the right to toggle back if we don't see movement at the local level."Newsom said the state is working with the county to send additional resources to help local officials address coronavirus cases. Despite this, the governor said interventions are not making enough of an impact, leading to reinstituting the stay-at-home order.The county's positivity rate has averaged 23% in the last week, compared with 5.7 % percent statewide. Newsom said there is also a need to decompress the county's hospital system, which other counties have helped do by accepting patients."I just sent 76 ventilators down to Imperial County. We are in the midst of the first wave of this pandemic. We are not out of the first wave. This disease does not take a summer vacation," Newsom said. Newsom added that he's awaiting a CDC study to determine if outside cases — for example, in hotspot Arizona — have contributed to the rise in cases in Imperial County.The Imperial Valley provides many of the vegetables in U.S. supermarkets during winter. 1553

Researchers from Florida Atlantic University released a video on Tuesday that shows how droplets disperse into the air from a person’s mouth.The researchers used different kinds of masks to analyze the disbursement of the droplets. The researchers also showed that without a mask, six feet of distance might not be enough to avoid infection.The FAU team tested a single-layer bandana-style covering, a homemade mask that was stitched using two-layers of cotton quilting fabric consisting of 70 threads per inch, and a non-sterile cone-style mask that is available in most pharmacies. The team used a mannequin, Laser lights and synthetic fog to help visualize the spread of the droplet from a cough..The researchers said that stitched quilted cotton masks worked the best in the simulation, with droplets from emulated coughs traveling just 2.5 inches from the mask. By comparison, without a mask, the droplets moved more than 8 feet, with some droplets traveling up to 12 feet during a heavy cough. The researchers also noted that the droplets remained suspended in midair for up to three minutes in the simulated environment.“We found that although the unobstructed turbulent jets were observed to travel up to 12 feet, a large majority of the ejected droplets fell to the ground by this point,” said Dhanak. “Importantly, both the number and concentration of the droplets will decrease with increasing distance, which is the fundamental rationale behind social-distancing.”FAU said that droplets from a cough traveled 3 feet, 7 inches from a bandana; 1 foot, 3 inches from a folded handkerchief; and 8 inches from a cone-style mask.“Preliminary results from our experiment reveal that significant concentrations of small particles from a turbulent jet such as from a heavy cough/sneeze can linger in still air for more than one minute. It only took the particles a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet,” said Siddhartha Verma, an assistant professor in FAU’s Department of Ocean and Mechanical Engineering.Last week, the University of Washington’s Institute for Health Metrics and Evaluation projected that 33,000 American lives would be saved between now and October 1 by near universal wearing of masks.Last month, a study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective.The CDC issued guidance in April to recommend mask wearing while in public, which has become a requirement to enter retail establishments in more than a dozen states.The CDC's guidance stressed several points: That wearing a face covering is not a substitute for social distancing, and that the public should not use medical or surgical masks. The recommendations suggest the public should use fabric or cloth that covers the mouth and nose.To view FAU's video, click here. Justin Boggs is a writer for the E.W. Scripps National Desk.

Presidential candidate Joe Biden spoke out on Wednesday on the shooting of Jacob Blake in Kenosha, Wisconsin. Blake was shot by police in Wisconsin on Sunday, causing unrest in Kenosha.Two officers from the incident have been placed on administrative leave. But protesters are calling for the officers to be fired and criminally charged for the shooting.Biden confirmed that he has talked to the Blake Family about the shooting.“What I saw on that video makes me sick,” Biden said. “Once again, a black man, Jacob Blake, been shot by the police in the broad daylight, the whole world watching”Biden said he told the Blake Family that “justice must and will be done.”While Biden applauded the protests, he decried the violence surrounding the protests. The violence culminated on Tuesday in the fatal shooting of two people. Police in Illinois arrested a 17-year-old in connection to the shootings.“As I said after George Floyd's murder, protesting brutality is a right and absolutely necessary, but burning down communities is not protest,” Biden said. “It's needless violence. Violence that endangers lives, violence that guts businesses and shutters businesses that serve the community. That's wrong. In the midst of this pain, the wisest words that I've heard spoken so far have come from Julia Jackson, Jacob's mother. She looked at the damage done in her community and she said this, quote ‘This doesn't reflect my son or my family. So let's unite, and heal, do justice, end the violence, and systemic racism in this country now.’Protests are expected to continue in Kenosha on Wednesday. President Donald Trump said that the state’s governor had accepted help from the National Guard, but the state’s governor, Democrat Tony Evers, said that he had not agreed to National Guard assistance, but would welcome federal assistance in a support role. 1859

President Donald Trump suggested Friday that the federal government could play a role in a possible recount of Florida's close Senate and gubernatorial races."If you look at Broward and Palm Beach (counties) to a lesser extent ... they have had a horrible history," Trump told reporters at the White House before departing for Paris."And if you look at the person, in this case a woman, involved -- she has had a horrible history," Trump said. It was unclear to whom Trump was referring, but Republican Gov. Rick Scott, the Republican candidate for Senate, has called the female election supervisors in Broward and Palm Beach counties "unethical liberals.""All of a sudden they are finding votes out of nowhere," Trump said of the Senate race.The President said Scott had "won by a comfortable margin," but accused Democrats of attempting to pad their margins."Every couple of hours, it goes down a little bit," Trump said of Scott's lead.Democratic Sen. Bill Nelson has pushed for a recount given that he trails Scott by such a slim margin. If the candidates in either contest are separated by 0.5% of the vote or less, the state will automatically recount ballots.Trump tweeted Thursday evening that reported irregularities in Broward and Palm Beach counties amounted to "another big corruption scandal having to do with election fraud."The President said officials involved in the "phony dossier" about his campaign's contacts with Russia are involved in the recount efforts. He was likely referring to Marc Elias, the lawyer Nelson's campaign has reportedly tapped to handle the recount effort, as Elias was also a lawyer for Hillary Clinton's campaign and was involved in commissioning that dossier of opposition research from Fusion GPS.The race for governor between GOP Rep. Ron DeSantis and Democratic Tallahassee Mayor Andrew Gillum is also close enough that a recount is possible.The-CNN-Wire 1910

He got into a white Chevrolet Tahoe that was waiting for him.A former Carolina Panthers wide receiver, Carruth spoke to CNN affiliate WSOC by phone days ahead of his release."I'm excited about just being out of here," Carruth said to the station. "I'm nervous just about how I'll be received by the public. I still have to work. I still have to live. I have to exist out there and it just seems like there is so much hate and negativity toward me." 833
