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) -- San Diego community leaders responded to comments made by the President, where he threatened to close down the US-Mexico border indefinitely if Mexico does not handle the wave of asylum seekers coming into the United States. Paola Avila with the San Diego Regional Chamber of Commerce is part of a nearly 100 person joint-delegation from San Diego and Baja California, going to Mexico City this Sunday, to champion US-Mexico relations. "Closing the border is not an option. Neither a portion nor all of it," Avila said. San Ysidro Port of Entry is the busiest land border crossing in the Western Hemisphere. More than 70,000 vehicles and 25,000 pedestrians cross into the United States every day.President Trump recently tried to direct .5 Billion from the Pentagon to build his campaign promise wall. But that was blocked by Senate Democrats and 12 Republicans. Now Baja-Cali business leaders fear the President will force a port and border shutdown. "Closing the border will be a profit-making operation," the President said. Not so, said Jason Wells with the San Ysidro Chamber of Commerce. As the Executive Director, he advocates for 650 businesses that have a zipcode one and a half miles from the border. He will be joining Avila on Sunday, in the advocacy delegation. He knows first hand the severe consequences of a shutdown. "Our daily lives are affected by the border crossings and how long that takes. So we certainly wish that not to be something to be toyed with," Wells said. When migrants rushed the border last November, San Ysidro Port of Entry was shut down for just five hours. In that short time, the city lost .3 million in revenue. This does not include the economic impacts to neighboring Chula Vista, National City, or San Diego.ABC News consultant John Cohen, who held a senior role at Homeland Security, said the last time there was a border shutdown was during the Reagan administration. He said it caused severe economic harm to both countries. "History tells us when you shut down the southern border, it does little to stop to flow of illegal drugs into the US. It does little to stop illegal immigration. You do cause significant economic harm to the US," Cohen told ABC News.Especially in this global economy, Avila said, where pesos and dollars are swiftly exchanged, and where commerce and culture are deeply intertwined. "Our economies, communities, workforce, our businesses are so integrated. It's like dissecting a person. Dividing a person in half is not viable," Avila said. Mexico's foreign minister responded in a tweet: "Mexico does not act on the basis of threats." 2651

SAN YSIDRO, Calif. (KGTV and AP) -- As the migrant caravan approaches the U.S.-Mexico border, several lanes in San Ysidro and Otay Mesa will close so new equipment can be installed.According to U.S. Customs and Border Protection, at least three northbound lanes in San Ysidro and one in Otay Mesa will close until after the caravan arrives.The closures are an effort by the Department of Defense to install concertina wire, and pre-positioning jersey barriers, barricades, and fencing as requested by CBP under Operation Secure Line. 551

SANTEE, Calif. (CNS) - Gov. Gavin Newsom signed into law a bill authored by Sen. Brian Jones, R-Santee, which extends immunity from liability for local governments that operate skate parks, the lawmaker announced Tuesday.Senate Bill 1003 follows a similar bill Jones wrote in 2015 while he was a member of the Assembly that provided a four-year immunity window for municipally operated skate parks. SB 1003 makes that immunity permanent."Senate Bill 1003 grants much-needed immunity from liability for communities that operate skate parks," Jones said. "Local skateboarders and sport riders get a safer place than the streets to carve, do McTwists or ollies, and taxpayers are not going to be liable for the occasional mishap that is inherent to all active sports."SB 1003 was sponsored by the County of San Diego, and as an urgency measure, goes into effect immediately.The bill was co-authored by Sens. Pat Bates, R-Laguna Niguel, and Ben Hueso, D-San Diego -- who both also represent parts of San Diego County -- and Sen. Brian Dahle, R-Bieber. 1055
