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

SAN YSIDRO, Calif. (KGTV) - Border Patrol officials in San Diego say they are preparing for the possibility of interactions with 7,000 immigrants seeking asylum at the U.S-Mexico border in San Ysidro.Mexico has already offered asylum to the migrant caravan, officials say. If the group reaches Tijuana, they will be denied entry into the United States.1,300 U.S. military troops are at San Ysidro to support the border mission, but not in a law enforcement role, according to military officials.The Army, Marines, and military police will fill in gaps along the border and erect barriers, creating an infrastructure to make it harder to cross illegally.Border protection officials also told 10News there is no place to put the migrants. During a tour of the San Ysidro Port of Entry Friday, journalists were allowed to tour the holding area but forbidden to take photographs. ICE detention facilities are already at capacity, officials say, and any more additions would push the problem to the breaking point.Anyone who enters the U.S. illegally will be arrested, Border Patrol officials say."We are not going to allow large groups of aliens to come to this county and to enter this country unaddressed,” said Rodney Scott, U.S. Customs and Border Protection.Scott added that if the caravan does visit the U.S., nothing is off the table in terms of stopping them, including a full border shutdown.The military says it views its mission at the border as temporary, and says it plans to be gone by December 15. 1516

SCRIPPS RANCH (KGTV): At the top of a trail along Semillon Boulevard and Pomerado Road, right next to a sign that reads, "No Dumping - 00 fine," sits a giant pile of wood chips.It's been there for years, growing and shrinking in size. But right now, people who live nearby say it's as big as they can remember."Yeah, it is a little larger than normal," says Douglas Burns, who lives in a home next to the pile.The wood chips are from trees cut down by maintenance workers in the area. The work is part of the Scripps Ranch Civic Association's maintenance contract with the city. The workers take the leaves to the dump but leave the wood chips behind.Bob Ilko, the President of the SRCA, says it saves money on beautification projects. He says the city doesn't have to pay to haul the wood chips and tree pieces away or buy fresh mulch when they need it for landscaping.The wood chips are used to help with weed control and ground cover across Scripps Ranch."It's natural here, it's generated here, it stays here," says Ilko, adding that there's also an environmental benefit since it keeps all the wood chips out of city landfills.Ilko says the pile is larger than usual right now, but that's because crews have been hard at work clearing away dead and dying trees from the area.And while the wood chips are on city-owned land, that does not mean they're available to the general public."It's city property," says Ilko. "If people take them, it defeats the purpose of keeping the wood chips here to save money."He also says contractors are not allowed to use the area to dump their wood chips.When asked if the pile presents a fire hazard, Ilko told 10News the Fire Department has been out to inspect the area, and they say there is no danger of any spontaneous combustion."It's not mulch, it doesn't heat up and break down like manure or mulch," says Ilko. 1889

SANTEE, Calif. (KGTV) — Cameras caught a thief wreaking havoc at an East County business park, culminating in several destructive acts after he realized he was locked in.Scott Trafton has seen the video countless times, but his emotions have yet to lessen."Aggravating and makes me angry," said Trafton, who owns XP Builders.Just before midnight last Thursday night, a truck is seen driving into a business park on Wheatlands Court. The truck, believed to be a Chevy Silverado, is parked in the dark for more than four hours, before a man emerges and heads toward Trafton's general contractor business. In the video, the man grabs items from the truck bed, before prying open a toolbox in the back. A knife at this side, the man would get away with more than a thousand dollars with of Trafton's tools. "It hurts being a small business. Every penny counts," said Trafton.Trafton is not the only victim. The thief left behind a trail of shattered truck windows and missing items."Basically took whatever wasn't bolted down," said Trafton.When the man went to leave, he was met by a gate, locked by someone who had left earlier. The camera spies him apparently chaining his truck to the fence and pulling forward, but he can't get the fence down."He then came over to another truck and broke a window. He then took a moving blanket to protect his truck and drove to another fence," said Trafton.In the video, you can see the flash of his lights, before his final act."He ran into the fence, spread it wide open and knocked it over," said Trafton.The repair bill will tally some ,000. Trafton worries about what the thief may do next."He doesn't care about the aftermath, as long as he gets what he wants," said Trafton.Anyone with information is asked to call the Santee sheriff's substation at 619-956-4000. 1818
