Scientists have accidentally developed a plastic-eating enzyme that may be used to combat one of the world's worst pollution problems.Researchers from Britain's University of Portsmouth and the US Department of Energy's National Renewable Energy Laboratory (NREL) made the discovery while examining the structure of a natural enzyme found in a waste recycling center a few years ago in Japan.They say the enzyme, Ideonella sakaiensis 201-F6, is able to "eat" polyethylene terephthalate, PET, which was patented as a plastic in the 1940s and is used in millions of tons of plastic bottles. 596

SANTA ANA, Calif. (CNS) -- With coronavirus cases spiking and several cities already opting to close their coastlines for the Fourth of July holiday, Orange County officials have announced that beaches will be closed on Saturday and Sunday.County CEO Frank Kim said the decision was made to align with most major cities along the coast, and out of concern that with indoor dine-in restaurants and bars closed the county's beaches would be more overrun than usual during the holiday weekend.County-operated beaches affected by the order are Aliso, Carmel Point, Table Rock, Thousand Steps, Treasure Island and West Street in Laguna Beach as well as Capistrano, Sal Creek, Baby and Strand in Dana Point and Poche in San Clemente and Bayside in Newport Beach.Gov. Gavin Newsom announced Wednesday that state beaches would also be closed in counties that close their coastline. Doheny, one of the more popular coastal points in the county, is a state beach in Dana Point.Kim said any time large groups of people congregate there is a risk of spreading the virus, but, "We believe there is a much lower risk in outdoor settings."Newport Beach, Laguna Beach, Huntington Beach and Seal Beach had already announced plans to close beaches for the holiday in light of spiking numbers of COVID-19 cases.San Clemente will be under a soft closure with only parking lot closures through the holiday weekend starting on Friday and continuing through Sunday, but Mayor Pro Tem Laura Ferguson said she does not wish to close the beaches.In Newport Beach, the decision to close beaches from 10 p.m. Friday to 6 a.m. Sunday followed news that two seasonal lifeguards in the city had tested positive for the coronavirus, and nearly two dozen others were placed in quarantine.Mayor Will O'Neill said some of the other lifeguards were showing symptoms. He noted the fastest growing demographic of infected patients are in their 20s and 30s."They're going to bars, going to house parties, not doing a great job of social distancing," O'Neill said, adding that he hopes they will now "take this seriously" as officials have to retreat on business and beach activity."I cannot in good conscience add more onto our lifeguards," he said. "We just can't responsibly ask our lifeguards to do more with less."O'Neill also implored beachgoers to stay away during the holiday weekend."Don't make our lifeguards and police chase you off," he said. "This is a hard enough year... This is a time we step up to where we need to be."The Huntington Beach City Council voted in an emergency meeting Wednesday night to close all city beaches, Huntington Harbor beaches, Sunset Beach and the Pier on July 4.Seal Beach's City Council voted to close its beaches and parking lots from 6 p.m. Friday through Sunday at sunrise.On Thursday, Kim and Orange County Health Care Agency Director Dr. Clayton Chau, who is also serving as the county's chief health officer, addressed a gaffe in the county's reporting of coronavirus test numbers in the county.County officials have been receiving results for both PCR swab tests and blood-based serology tests. PCR tests are considered much more accurate because a specimen is tested, but there is a high error rate for many serology tests, which measure antibodies created after someone gets infected.The number of both types of tests the county was receiving were combined on May 28, a mishap discovered on June 3, Chau said. County officials stopped reporting both numbers at that point because the serology tests are not as reliable, Chau said.Officials intended to correct the numbers it was reporting on the county's website, but a newly redesigned site was delayed until June 26 when the corrected data was made public -- meaning incorrect testing data was provided for several weeks, Chau said.Kim and Chau said they should have informed the public and county board earlier of the mistake. Orange County Board of Supervisors Michelle Steel said at a news conference Thursday she found out about it from a report in The Orange County Register.Kim said the mistake did not factor into the county's application to the state to open up businesses, because the data came from the state and California public health officials were aware of the difference.The county's beach closures come on the heels of a county order Wednesday closing all bars in the county, an order that was also put in place later in the day by Newsom, affecting 19 counties, including Orange County.The county order affects all bars, pubs, breweries and brew pubs that do not offer dine-in meals. Establishments serving dine-in food can only sell alcohol in the same transaction as a meal.The closure order was expected ahead of the holiday weekend, given similar action already taken in the surrounding counties of Los Angeles, San Diego and Riverside.On Thursday, county health officials announced 652 more coronavirus cases and nine more deaths, bringing the county's totals to 15,065 cases and 354 fatalities. On Tuesday, the county reported a one-day record 779 newly confirmed cases.Chau said hospital officials say the number of patients 18 to 30 years old is trending up, "but it appears they are recovering much quicker than the elderly population."Of Thursday's reported fatalities, four were from skilled nursing facilities and one from an assisted living facility. In total, 181 of the county's fatalities were from nursing homes.Last week was the deadliest of the pandemic in Orange County, with 56 deaths reported. Since Sunday, the county has reported 31 fatalities.The number of hospitalized patients in Orange County rose from 542 Wednesday to 556, with the number of patients in intensive care increasing from 192 to 193. As of Wednesday, six of the patients were from Imperial County to help with an overflow there.County officials reported that they had performed 248,028 COVID-19 tests, with 7,862 documented recoveries as of Wednesday.Newsom announced earlier this week that Orange County, along with Solano, Merced and Glenn counties, had been added to the state Department of Public Health's watch list due to increasing percentages of positive tests.The county's case rate rose from 126.4 per 100,000 on Wednesday to 152.5 per 100,000 Thursday. The positive test rate increased from 10.4% on Wednesday to 12%, according to health officials.The state has set a desired standard average of 25 positive cases per 100,000 over a 14-day period, and a seven-day average positivity rate of 8%.Orange County's three-day average increase of hospitalized patients is 11.4%, which exceeds the state's threshold of 10%.Health officials insisted Orange County is in good shape in terms of hospital beds available. The county has 36.1% of its intensive care unit beds available, above the state threshold of 20%, and has 63.5% of its ventilators available, above the state standard of 25%.In the county's jails, 404 inmates have tested positive for COVID-19 with 390 having recovered. There are 14 inmates in medical isolation with symptoms and officials were awaiting results of 39 tests.Sheriff Don Barnes, who has been criticized for declaring at a Board of Supervisors meeting that he did not intend to be the "mask police," issued a statement on Thursday saying that face coverings are "important" to fight the spread of the virus.Barnes said it was impractical to enforce face-covering mandates."As many other industries are gaining compliance through an education- first approach, deputies will continue to educate the public about the statewide face-covering requirement and will request voluntary compliance," Barnes said."During this time of strained police community relations, one only needs to look to New York and other jurisdictions where enforcement has resulted in uses of force and negative outcomes to recognize that an education- first strategy, aimed at obtaining voluntary compliance, is the most sensible and realistic approach."I expect that Orange County residents will continue to use common sense and responsibly wear a face covering, in addition to other recommended best practices such as frequent hand washing and maintaining physical distance, for the benefit of their own health as well as the collective health of the community. We must do what is necessary to stop the transmission of COVID-19."Newsom this week said he has established "strike teams" of state officials who will seek to enforce compliance with COVID-19 guidelines.Kim told reporters "enforcement can be a challenge" for county officials because they do not always have jurisdiction. In many cases it is up to local cities to enforce regulations, Kim said. 8646

SAN FRANCISCO (AP) — She was a self-described "adrenaline junkie," and he took "wow-worthy photos" of the couple posing at the edge of cliffs and jumping from planes that appeared on social media and a travel blog that attracted thousands of followers.In one post at the Grand Canyon this spring, 30-year-old Meenakshi Moorthy even warned daredevils who try to snap selfies from dangerous heights: "Did you know that wind gusts can be FATAL???" The caption accompanies a photo of Moorthy sitting on the edge of the canyon's North Rim.The couple's latest trip turned out to be their last. Moorthy and her husband, Vishnu Viswanath, 29, who were Indian expats living in California, fell to their deaths in Yosemite National Park last week while taking a selfie, the man's brother said Tuesday.RELATED: Brother: Indian tourists died in Yosemite fall while taking a selfieThey set up their tripod near a ledge at a scenic overlook in the California park, Viswanath's brother, Jishnu Viswanath, told The Associated Press. Visitors saw the camera the next morning and alerted park rangers, who "used high-powered binoculars to find them and used helicopters to airlift the bodies," he said.Rangers found their bodies about 800 feet (245 meters) below Taft Point, where visitors can walk to the edge of a vertigo-inducing granite ledge that offers spectacular views of the Yosemite Valley below.Their thrill-seeking social media posts foreshadow the couple's link to the growing problem of selfie deaths.RELATED: 2 die after falling from?overlook?in Yosemite National ParkA study published this month in the Journal of Family Medicine and Primary Care said 259 people had died taking selfies between October 2011 and November 2017.The report, based on findings from researchers in India who scoured worldwide media reports, said the main causes of selfie deaths were drowning, usually involving people being washed away by waves or falling from a boat, followed by people killed while posing in front of a moving train, deaths involving falls from high places or while taking pictures with dangerous animals.More than 10 people have died at Yosemite this year, some from natural causes and others from falls, park spokesman Scott Gediman said.RELATED: Photographer finds mystery engagement couple in viral Yosemite photoMoorthy and Viswanath were born in India and had lived in the United States for a few years, most recently in the San Francisco Bay Area.

She said Moorthy and Viswanath were both good students who were fond of traveling and had married at a Hindu temple in Kerala in southern India four years ago.Moorthy described her and her husband as "travel obsessed" on their blog, "Holidays & Happily Ever Afters," which was taken down Tuesday. It was filled with photos of the couple in front of snowy peaks and on romantic trips across Europe, where they took selfies from a gondola in Venice, at the Leaning Tower of Pisa and at the Vatican.RELATED: More than 250 people around the world have died taking selfies since 2011Moorthy wanted to work full time as a travel blogger, her brother-in-law said. She described herself as a "quirky free spirit" and "an ardent adrenaline junkie — roller coasters and skydiving does not scare me," Viswanath said.She posed at the edge of the Grand Canyon wearing a Wonder Woman costume, writing, "A lot of us including yours truly is a fan of daredevilry attempts of standing at the edge of cliffs — and skyscrapers. But did you know that wind gust can be FATAL??? Is our life just worth one photo?"Her husband's Facebook cover photo shows the couple smiling, with arms around each other standing at a Grand Canyon precipice. "Living life on the edge," he wrote.RELATED: Teen dies after falling while taking?selfie?in Yosemite National ParkIn a post from July 2017, the couple celebrated their wedding anniversary by skydiving in Santa Barbara, California.

I believe i can touch the skyyy," she wrote in the post. "Aaaand touch the sky I did from an effin' 18000 feet thanks to the unconditional love-ninja in my life, Vishnu, who literally took this year's anniversary surprise a notch 'higher' than last year's hot air ballooning adventure, by gifting this adrenaline junkie with one of the highest tandem skydives in the world!"She also blogged about depression.

He said she made him a little nervous because she was close to the edge.RELATED: Hiker falls to his death during thunderstorm at Yosemite"She was very close to the edge, but it looked like she was enjoying herself," said Matteson of Oakland, California. "She gave me the willies. There aren't any railings. I was not about to get that close to the edge. But she seemed comfortable. She didn't seem like she was in distress or anything."The travel advice website MyYosemitePark.com posted a photo of Taft Point to illustrate its "bad selfies" list, warning tourists: "Don't pose on top of a huge granite drop-off." It added, "It would only take a loose rock or bad footing to plummet."Yosemite spokeswoman Jamie Richards said officials were investigating the deaths, which could take several days.In India, after a rash of selfie-related deaths, the Tourism Ministry in April asked state government officials to safeguard tourists by installing signs in areas where accidents had occurred declaring them "no-selfie zones." 6571

SAN FRANCISCO (AP) — The Saudi government recruited two Twitter employees to get personal account information of their critics, prosecutors said Wednesday.A complaint unsealed in U.S. District Court in San Francisco detailed a coordinated effort by Saudi government officials to recruit employees at the social media giant to look up the private data of thousands of Twitter accounts.The accounts included those of a popular critic of the government with more than 1 million followers and a news personality.It also alleged that the employees — whose jobs did not require access to Twitter users' private information — were rewarded with a designer watch and tens of thousands of dollars funneled into secret bank accounts. They were charged with acting as agents of Saudi Arabia without registering with the U.S. government.The Saudi government had no immediate comment through its embassy in Washington.Twitter acknowledged that it cooperated in the investigation and said in a statement that it restricts access to sensitive account information "to a limited group of trained and vetted employees.""We understand the incredible risks faced by many who use Twitter to share their perspectives with the world and to hold those in power accountable," the statement said. "We have tools in place to protect their privacy and their ability to do their vital work."Ahmad Abouammo, who left his job as the media partnership manager for Twitter's Middle East region in 2015, was also charged with falsifying documents and making false statements to obstruct FBI investigators — offenses that carry a maximum penalty of 30 years in prison if convicted.At his appearance in Seattle federal court Wednesday, Abouammo was ordered to remain in custody pending a detention hearing set for Friday.His lawyer, Christopher Black, declined to comment, as did Abouammo's wife, who did not give her name.Investigators alleged that a Saudi citizen working as a social media adviser for the Saudi royal family recruited Twitter engineer Ali Alzabarah. The two met in Washington. D.C., around the same time the adviser, Ahmed Almutairi, met with someone named in the complaint as Royal Family Member 1."Within one week of returning to San Francisco, Alzabarah began to access without authorization private data of Twitter users en masse," the complaint said.The effort included the user data of over 6,000 Twitter users, including at least 33 usernames for which Saudi Arabian law enforcement had submitted emergency disclosure requests to Twitter, investigators said.After being confronted by his supervisors at Twitter, Alzabarah acknowledged accessing user data and said he did it out of curiosity, authorities said.Alzabarah was placed on administrative leave, his work-owned laptop was seized, and he was escorted out of the office. The next day, he flew to Saudi Arabia with his wife and daughter and has not returned to the United States, investigators said.A warrant for his and Almutairi's arrests were issued as part of the complaint. 3032
