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 (CNS) - Orange County was removed from California's coronavirus monitoring list Sunday, starting the clock for all public schools in the county to potentially reopen in early September.The state mandates a county must be off the watch list for 15 days before all schools can reopen. Orange County's data on hospitalizations and other key metrics have been moving in the right direction, with the rate of county residents testing positive for COVID-19 at 5-point-4 percent, below the state's desired threshold of 8 percent.Underscoring the positive trends, county health officials reported just 153 newly confirmed cases of COVID-19 and one additional death Sunday, bringing the county's totals to 45,954 cases and 897 fatalities.The data on hospitalizations continued to move in the right direction, with 380 people hospitalized and 111 of those in intensive care. Those numbers were 392 and 110 on Saturday, 397 and 117 on Friday, and 400 and 118 on Thursday, according to the Orange County Health Care Agency.The county's case rate per 100,000 residents dropped from 92.9 to 90.2, which is still far higher than the California Department of Public Health threshold of 25 per 100,000 residents.The county has 29% of intensive care unit beds available, which is better than the state's 20% threshold. And the county's hospitals have 58% of their ventilators available, well above the state standard of 25%.The OCHCA reported that 594,082 COVID-19 tests have been conducted, including 5,163 reported Sunday. There have been 37,452 documented recoveries.Orange County could be placed back on the list should it be flagged for exceeding any one of six different metrics for three consecutive days. Those metrics are the case rate, the percentage of positive tests, the average number of tests a county is able to perform daily, changes in the number of hospitalized patients and the percentage of ventilators and intensive care beds available.The decision to reopen schools would still be left to individual districts. Orange County officials say 24 elementary schools have already been approved to reopen, including six in the Los Alamitos Unified School District.For parents still leery of returning students to classrooms, Dr. Clayton Chau, the county's interim chief health officer and director of the Orange County Health Care Agency, said the county "encourages" them to continue online learning, "especially children who are at a higher risk."The county will provide tests for staff and students and a "full medical team" that includes pediatricians, while infectious disease experts from Children's Hospital of Orange County and UC Irvine "will be standing by to assist when needed," Chau said.Wednesday was the first day the county fell below the state's monitoring thresholds, Chau said.It is possible various business sectors that are shut down for commerce indoors may be allowed to return to normal, Chau said. County officials are expecting "new guidance" from the state this week. 3010

SAN FRANCISCO (AP) — The robotic car company created by Google is poised to attempt a major technological leap in California, where its vehicles will hit the roads without a human on hand to take control in emergencies.The regulatory approval announced Tuesday allows Waymo's driverless cars to cruise through California at speeds up to 65 miles per hour.The self-driving cars have traveled millions of miles on the state's roads since Waymo began as a secretive project within Google nearly a decade ago. But a backup driver had been required to be behind the wheel until new regulations in April set the stage for the transition to true autonomy.RELATED: 2018 could be a pivotal year for driverless carsWaymo is the first among dozens of companies testing self-driving cars in California to persuade state regulators its technology is safe enough to permit them on the roads without a safety driver in them. An engineer still must monitor the fully autonomous cars from a remote location and be able to steer and stop the vehicles if something goes wrong.California, however, won't be the first state to have Waymo's fully autonomous cars on its streets. Waymo has been giving rides to a group of volunteer passengers in Arizona in driverless cars since last year. It has pledged to deploy its fleet of fully autonomous vans in Arizona in a ride-hailing service open to all comers in the Phoenix area by the end of this year.But California has a much larger population and far more congestion than Arizona, making it even more challenging place for robotic cars to get around.RELATED: NTSB report: Uber self-driving SUV saw pedestrian in Arizona but didn't brakeWaymo is moving into its next phase in California cautiously. To start, the fully autonomous cars will only give rides to Waymo's employees and confine their routes to roads in its home town of Mountain View, California, and four neighboring Silicon Valley cities — Sunnyvale, Los Altos, Los Altos Hills, and Palo Alto.If all goes well, Waymo will then seek volunteers who want to be transported in fully autonomous vehicles, similar to its early rider program in Arizona . That then could lead to a ride-hailing service like the one Waymo envisions in Arizona.But Waymo's critics are not convinced there is enough evidence that the fully autonomous cars can be trusted to be driving through neighborhoods without humans behind the wheel.RELATED: Potential "game changer" could make commutes more relaxing"This will allow Waymo to test its robotic cars using people as human guinea pigs," said John Simpson, privacy and technology project director for Consumer Watchdog, a group that has repeatedly raised doubts about the safety of self-driving cars.Those concerns escalated in March after fatal collision involving a self-driving car being tested by the leading ride-hailing service, Uber. In that incident, an Uber self-driving car with a human safety driver struck and killed a pedestrian crossing a darkened street in a Phoenix suburb.Waymo's cars with safety drivers have been involved in dozens of accidents in California, but those have mostly been minor fender benders at low speeds.RELATED: Waymo self-driving car crashes in ArizonaAll told, Waymo says its self-driving cars have collectively logged more than 10 million miles in 25 cities in a handful of states while in autonomous mode, although most of those trips have occurred with safety drivers.Waymo contends its robotic vehicles will save lives because so many crashes are caused by human motorists who are intoxicated, distracted or just bad drivers."If a Waymo vehicle comes across a situation it doesn't understand, it does what any good driver would do: comes to a safe stop until it does understand how to proceed," the company said Tuesday. 3827

SANTEE, Calif. (KGTV) - Surveillace video shows thieves stuffing a car after breaking into a popular Santee restaurant hit hard by the pandemic and a recent tragedy.Every time restaurant owner Maria Dellarsina looks at the surveillance video she gets anxious."All kinds of emotions. I feel angry, and I feel sad," said Dellarsina.The roller coaster of emotions began after a Thanksgiving morning break-in. The 43-year old Jimmy's Restaurant of Santee was ransacked by thieves. The HVAC access on the roof is the likely entry point.Video shows three people stuffing items into their car, as they helped themselves to whatever they wanted."They took food, liquor, checks, cash, laptop computer, and sports memorabilia," said Dellarsina.The items stolen were just part of the loss. The thieves also cut the power and left the refrigerators open, so all the food had to be tossed."When I saw food going into the trash is when I broke down," said Dellarsina.The total loss more than ,000.The restaurant had to be shut down for a few days, including the day after Thanksgiving, their busiest day of the year."One thing after another ... devastation," said Dellarsina.Beginning in March, restaurant was shut down for months during the pandemic. In May, her husband and co-owner John, passed away from lung cancer."I didn't know if I wanted to open again. We did it. I got my strength back to continue his legacy, but it's hard on us.So far, the pandemic has slashed revenues by more than 60%. The burglary has served up more pain, but Dellarsina vows to continue."It's been very rough, but this is not going to stop us," said Dellarsina.The restaurant is insured, but it's not clear how much will be covered.Anyone with information is asked to call Crimestoppers at 888-580-8477. 1783
