SAN DIEGO COUNTY (KGTV)-- While most beaches in San Diego County are entirely closed due to the Coronavirus pandemic, Coronado, Torrey Pines, and Oceanside do not have hard-closures. However, most of the visitors at the still-open beaches were doing their part in maintaining proper social distance. Get out and stretch out. Many people found one of the rare places in San Diego County to do so: Coronado Beach. "All the gyms, and everywhere you can get a little exercise, are closed," Manhattan Beach resident, Ryan Darling said. "I actually came out just to stretch my legs a little bit and get out of the house to do some lunges." Darling is visiting a friend in Coronado. He was worried the beach here would be packed. But many are finding it to be pretty mellow. "It's just as nice to see that it's not crazy on this nice, beautiful Saturday," Coronado resident, Brenda Byrnes said. Coronado Lifeguards periodically make announcements over the loudspeakers to take enforcement to the next level. "We're trying as hard as we can to keep the beach open. So we ask that you guys remain in motion," lifeguards said. If they see anyone loitering, sunbathing, or quietly sitting on the sand, they tell them to get a move on. It's a message most people seem to be following. "I went the whole way, and we just wave hi to one another from six feet and keep going," Darling said. The same goes for Oceanside. The beaches there have similar soft-closure rules. The parking lots, Pier, picnic areas, and playgrounds are closed. Congregating is strictly prohibited. These cities are following State guidelines practiced at Torrey Pines State Beach. Parking lots are closed, so visitors must hike into the beach. But some fortunate folks found street parking. "It's our lucky day!" visitor, John Hughes laughed. "Get out, get some sun, and then we'll go back home and hibernate."So far, visitors at the still-open beaches seem to be taking social distancing seriously. It's because if they do not, they know this luxury may be taken away at any time. "I hope they remain open, and to be used just the way they are right now," Byrnes said. "But if it gets too crowded, then I'm for closing them." 2195

SAN DIEGO (KGTV/AP) - Actor James Cromwell is facing a trespassing charge for an animal rights protest at SeaWorld San Diego.Cromwell wore a "SeaWorld Sucks" t-shirt during the protest at the Orca Encounter show July 24.He and six other demonstrators were removed by security.VIDEO: James Cromwell protests at SeaWorldCromwell previously said he would serve jail time rather than pay fines.  404

SAN FRANCISCO (AP) — California fire authorities say Pacific Gas & Electric Co. power lines sparked the deadliest and most destructive wildfire in state history.Cal Fire said Wednesday the lines in the Pulga area ignited the Nov. 8 fire that killed 85 people in Paradise.The investigation also identified a second nearby ignition site involving vegetation and electrical distribution lines, also owned and operated by the San Francisco-based utility.The second fire was quickly consumed by the initial fire.Lynsey Paulo, a spokeswoman for PG&E, did not immediately comment.The fire in Butte County destroyed nearly 15,000 homes.The nation's largest utility filed for Chapter 11 bankruptcy in January as it faced tens of billions of dollars in potential liability costs related to wildfires in 2017 and 2018. 823

SAN FRANCISCO (AP) — Google announced Wednesday it has achieved a breakthrough in quantum computing, saying it has developed an experimental processor that took just minutes to complete a calculation that would take the world's best supercomputer thousands of years.The feat could open the door someday to machines so blazingly fast that they could revolutionize such tasks as finding new medicines, developing vastly smarter artificial intelligence systems and, most ominously, cracking the encryption that protects some of the world's most closely guarded secrets.Such practical uses are still probably decades away, scientists said. But the latest findings, published in the scientific journal Nature, show that "quantum speedup is achievable in a real-world system and is not precluded by any hidden physical laws," the researchers wrote.RELATED: Google Maps will now allow drivers to report hazards, slowdowns and speed trapsBig tech companies including Microsoft, IBM and Intel are avidly pursuing quantum computing, a new and somewhat bewildering technology for vastly sped-up information processing.While conventional computing relies on bits, or pieces of data that bear either a one or zero, quantum computing employs quantum bits, or qubits, that contain values of one and zero simultaneously.But quantum computing requires placing the fragile and volatile qubits in colder-than-outer-space-refrigerators to control them.Google's quantum processor looks like an upside-down garbage can, out of which comes a series of tubes used to conduct signals to a chip. The whole thing is stored in a cool chamber to protect the chip.RELATED: Google unveils new Pixel 4 smartphone, Pixel BudsGoogle said that its quantum processor, called Sycamore, finished a calculation in 3 minutes, 20 seconds — and that it would take the world's fastest supercomputer 10,000 years to do the same thing.The calculation was a random sampling problem, similar to looking at the various combinations that could come from dice or a gambling machine. It has little practical value, other than to test how well the processor works."The more interesting milestone will be a useful application," said Chris Monroe, a University of Maryland physicist who is also the founder of quantum startup IonQ.Google's findings, however, faced pushback from other industry researchers. A version of Google's paper leaked online last month.IBM took issue with Google's claim that it had achieved "quantum supremacy," or the point when a quantum computer can perform a calculation that a traditional computer can't complete within its lifetime.IBM researchers said that its IBM-developed supercomputer, called Summit, could actually do the calculation in 2.5 days.Google disputed IBM's claims.Whether or not Google achieved "quantum supremacy," the research suggests the field is maturing."The quantum supremacy milestone allegedly achieved by Google is a pivotal step in the quest for practical quantum computers," John Preskill, the Caltech professor who coined the term "quantum supremacy," wrote in a column after the paper was leaked.It means quantum computing research can enter a new stage, he wrote, though a significant effect on society "may still be decades away."One feared outcome — though experts said it is a long way off — is a computer powerful enough to break today's best cryptography.Quantum computers might also one day lead to the development of better artificial intelligence systems to guide financial portfolios, crop yields or transportation routes.The promise of such applications has attracted interest from the U.S., China and other governments. President Donald Trump last year signed a measure to spend more than .2 billion over five years for quantum research across the federal government. 3797

SAN DIEGO (KGTV)-- With the increase in park usage since the start of the COVID-19 pandemic, San Diego Park Rangers are noticing a slight increase in vandalism at city parks and trails.On a scale of one to ten, hiking up Cowles Mountain was a bit of a challenge."For me, an eight," six-year-old Joaquin Santaruse said.He, his brother, and two buddies zig-zagged up San Diego's highest peak Wednesday to get away."It's fun to be in nature sometimes," older brother Mateo Santaruse said. "It's a great view up there, and there's a bunch of cool rocks, and in fact, we found a pink one."Many people have noticed and posted about an uptick in graffiti at parks and trails across the nation. Zion National Park published a post on their Facebook page, showcasing the recent vandalism incidents. In it, they are pleaded with people not to disrupt nature during their visit."We just saw that it was painted all pink, and we were like, 'Wow, look at that rock!'" Mateo said.But that awe turned into a little disappointment for the young boys."The chemicals in the spray paint," friend Aaron Heredia said."The animals can try to lick on it and stuff, and then it's toxic," Mateo followed.Tim Graham with the city of San Diego, says graffiti has both environmental and financial impacts. He sent ABC 10News a statement reading,"Because of the location and size of some of the rocks, park rangers are unable to remove the rocks or the paint safely. The City is looking into contracting with a qualified vendor that can safely remove and capture the paint from the rocks."This, unfortunately, becomes an unnecessary expense for taxpayers. So instead of leaving a mark, Graham is asking San Diegans only to leave footprints.If you spot graffiti, email the city at askparks@sandiego.gov or file a report at the city's Parks and Recreation website. 1841
