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

Scientists and doctors are watching closely as some children head back to school with in-person learning. Many are hoping extra precautions will keep students safe. But there are big questions surrounding the safety of lunchtime."If you’re doing all the right things, masking kids, keeping them distanced and washing hands, you are going to decrease your chance of transmission. But if they take masks off and they're indoors in close proximity, you’ve sort of derailed your entire plan because lunchtime is the most high-risk time to transmit COVID-19 or any illness," says Dr. Tanya Altmann, a pediatrician with the American Academy of Pediatrics.Dr. Altmann says it's important during lunchtime, that children are at least six feet apart and not facing each other."I would recommend that in any area around the country where you can eat lunch outdoors, to eat lunch outdoors because that is safer," says Dr. Altmann.Dr. Jay Varkey, the hospital epidemiologist at Emory Hospital in Atlanta, Georgia, agrees that school administrators should have students eat outside, when weather permits."You can’t wear a mask and eat a lunch. Depending on the age of the children, I don’t think a lot of school-age children are maybe the most diligent in terms of washing their hands before and after a meal. So, I do think it’s a potentially high-risk area," says Dr. Varkey.Dr. Varkey adds, the same goes with school employees who may be heading to a teacher's lounge for lunch or a cup of coffee. Those school spaces need to be recreated to allow for more social distancing."First and foremost, it goes back to what metrics you need to open up schools. As much as I am a believer in in-person learning and the benefits of it, the reality is, in order to open safely you have to have control of COVID-19 transmission in the community," says Dr. Varkey.As public health officials work to battle COVID-19 in their communities, Dr. Altmann recommends schools reimagine spaces on their campuses.Dr. Altmann says, “You could maybe repurpose your library as a teacher break room. You could use the auditorium as a lunch space or even the gym since we’re not going to be having contact sports."Dr. Altmann says children eating lunch inside their classrooms is also okay, as long as no desks are facing each other. A big adjustment for kids as some head back to school for in-person learning, with many changes to their daily routines. 2425

SAN TAN VALLEY, Ariz. — In-person schooling was supposed to begin Monday for the J. O. Combs School District, but a move by teachers and staff forced the district to cancel school for the day.On Friday, a J. O. Combs Spokesperson said 109 teachers and staff requested not to work on Monday."Due to these insufficient staffing levels, schools will not be able to re-open on Monday as planned. This means that all classes, including virtual learning, will be canceled," wrote J. O. Combs Superintendent Dr. Gregory Wyman in a letter to parents on Friday. "At this time, we do not know the duration of these staff absences, and cannot yet confirm when in-person instruction may resume."A teacher in the district said that one of the reasons teachers decided to call out Monday was that they felt unprepared to teach students virtually and in-person.Teachers are expected to simultaneously instruct students in the classroom and those at home via live stream. One teacher believes they were not adequately prepared to cater to both types of learners, since all of the educators' attention has been on executing online learning."The issue is that [a] teacher would not be able to tend to the online learners that are on Google," said a teacher in the district. "Even in-class learning must be modified for online. So it's a lose-lose for both types of learners."That teacher said only one hour of training was given for the live stream equipment."Some classes have as many as 36 [on] their roster or more. About half are choosing to stay home, so we really need to service our online learners."Aside from the feeling of unpreparedness from teachers, many feel unsafe since benchmarks set by the Arizona Department of Health Services have yet to be met by any of the school districts."My coworkers do not feel safe. Metrics being met is a big deal. We also want to keep at-risk teachers with online kids."The district's Governing Board voted against the superintendent's recommendation to move in-person education to October, and also shot down a motion to forgive a ,000 penalty for teachers, ,500 for administrative staff, who decide to break their contract due to COVID-19.Teachers in the district hope to come to a resolution with the district to continue online-only teaching until health benchmarks are met.On Monday, students of Combs High School are also staging a march in support of teachers who did not call out at 10 a.m.The district says they will monitor the situation and expects to have an update no later than 5:00 p.m. Monday.This story was originally published by Adam Waltz on KNXV in Phoenix. 2619

SANTA ANA, Calif. (AP) — After Los Angeles County residents got an automated phone call reporting a mistake was on their November ballot, county officials issued an alert to voters that there was no such error.The calls — and a mailer dubbed a ballot "correction" — were part of an advertising blitz by Proposition 6 supporters trying to drive home a message to voters to overcome what they see as a misleading title and summary on the ballot initiative.Proposition 6 would repeal an increase in fuel taxes and vehicle fees that is slated to fund billion in transportation projects a year.RELATED: Poll: Support strong for Proposition 6, which repeals California's gas taxIts title on the ballot begins with: "Eliminates certain road repair and transportation funding." Proponents say that doesn't convey quickly enough its mission, which is why they titled it a "Gas Tax Repeal Initiative" in large letters on their mailer.The feud over messaging comes just weeks before the election, though complaints about ballot language are hardly new. Since elected officials craft the title and summary that voters read on the ballot, Republicans frequently contend they are at a disadvantage since California's Legislature and government offices — including those tasked with drafting and publishing ballot language — are solidly in Democrats' hands."We very often have these fights," said Thad Kousser, chairman of political science at the University of California, San Diego. "(The proponents) wanted it to only talk about what voters would get, not what voters would lose, and so they are well within their rights to make this their central campaign message."RELATED: AP: California agency, gas tax backers worked closely togetherProponents can challenge ballot language in the courts but didn't for Proposition 6, a constitutional amendment that also seeks to require voter approval for future fuel tax hikes.Instead, supporters have focused their efforts on branding the measure as a repeal of a gasoline tax hike they say is making California too expensive."We know when voters know 'Yes on Prop 6' is the gas tax repeal, they are more likely to support it," said Dave McCulloch, a spokesman for proponents. "Lawyers are expensive, and we feel money is best used by educating voters."REPORT: Gas tax funds reportedly being used to campaign against Prop 6Opponents, who argue the tax revenues are critical to upgrading the state's crumbling roads and bridges, have called the advertising deceptive. They said they also would have preferred messaging more favorable to their cause and that proponents had the chance to mount a court challenge and didn't."We find it disgraceful and deceptive that they would emulate an official voter guide with fake mailers," said Robin Swanson, a spokeswoman for the campaign against Proposition 6. "If we were writing the title and summary, we would call it, 'The attack on roads and bridges.'" We didn't get our way either, but we're not trying to deceive voters."Opponents, backed by construction industry groups and unions, are campaigning to show voters how revenues from the 12-cent-per-gallon increase in gasoline excise taxes are translating to road and transit fixes in their neighborhoods, she said.RELATED: Caltrans' gas tax freeway signs raise concerns with FedsThe battle over language comes as polling by the nonpartisan Public Policy Institute of California shows the repeal effort trailing. In a mid-October poll, 41 percent of likely voters said they planned to vote for the initiative, and 48 percent were opposed. A January poll showed 47 percent of likely voters favored repealing the gas tax increase.McCulloch said the shift shows ballot language matters since earlier polling didn't include the measure's official title. Swanson said it showed the campaign against the measure, which took off over the summer, has resonated with voters.Opponents also have raised million, compared with million raised by supporters.RELATED: California campaign watchdog investigates gas tax campaignKeir DuBois, 41, said he received one of the correction-styled mailers in coastal Ventura northwest of Los Angeles. DuBois, who opposes the repeal, said he knew it was an ad but didn't like getting an official-looking communication that was labeled a "correction" from a political campaign."I felt like they were trying to pull one over on people who want to believe voting against every tax is a good thing," he said.Brian Greene, who has seen the mailers posted online and wants the tax hike rolled back, said he feels just the opposite.RELATED: San Diego projects receive funding due to controversial gas tax"It is just getting the conversation started about what the phrasing actually means on the bills we're voting on," said the 25-year-old from Los Angeles. "I think the layperson doesn't understand the government rhetoric. They make it as complicated as possible."In this month's poll, the measure had more support in Orange County and San Diego County, home to Republican former councilman and initiative author Carl DeMaio. Most respondents in the San Francisco Bay Area said they'd vote against it.In addition to election mailers and calls, Proposition 6 supporters have led a bus tour and put video ads on screens at gas stations that drivers see while filling up. They also held campaign events at gas stations offering discounted fuel.Mary-Beth Moylan, professor at University of the Pacific's McGeorge School of Law in Stockton, thinks proponents went too far in mimicking election announcements."I don't have a problem with them putting a mailer out," said Moylan, who teaches a seminar on initiatives. "It is another thing to say, 'We're going to masquerade as an official state actor and tell you that there is a correction to your ballot.' Adding that level of manipulation to the process, I think, is problematic." 5909
