SAN DIEGO, Calif. (KGTV) - NOAA's Climate Prediction Center released the updated outlook for winter 2020-2021 expectations, and the report shows the increased confidence for a moderate La Nina winter.National Weather Service Meteorologist Alex Tardy said La Nina winters mean cold water along the equator, which are already present in October. These cold waters can have a domino impact on the globe, including warmer waters in the Atlantic and ultimately a higher risk of hurricanes, and also a more northern jet stream over the west coast, keeping moisture isolated more north and leading to dry conditions in Southern California.This dry winter coupled with San Diego’s recent weather history could be a recipe for disaster. The last two winters have been wet in San Diego, with most areas in San Diego County getting 1.5 times their usual rainfall during the most recent winter. This increased moisture helped vegetation grow, then the summer of 2020 brought record-breaking heat, drying that vegetation out. That, coupled with a lack of monsoon moisture in 2020, means there is dry vegetation that could be fuel for fires.“Any type of fire is going to be a problem in Southern California because the conditions are so dry,” said Tardy.He added that a new water year just began Oct. 1, 2020, so while the last water year had impressive rain totals, a new year has started.“So regardless of what happened last winter, we kind of reset now. Now we’re in a whole new year and unfortunately, things are looking very stressed as far as fire conditions,” said Tardy.He said rain is not out of the question for a La Nina year, but it will be more variable. Winter is the best time for Southern California to accumulate rain, and with the decreased chances of rain, Southern California could move into drought conditions by the end of the winter. 1850

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, Calif. — As we work to manage the pressure of the pandemic, a new device could take away some of the stress.San Diego State University (SDSU) engineers, biologists, mathematicians, computer scientists, and public health experts have worked together to develop a wearable device to detect early, remote detection of lung function abnormalities.“Knowing the current status of our health, I think that will give a lot of benefit," said Kee Moon, a researcher, and professor of mechanical engineering at SDSU. The size of a Band-Aid, the wearable device contains medical-grades sensors, collecting more than 4,000 data points per second. Placed on a person’s chest, it monitors heart and lung health, looking for problems in real-time.The device can detect abnormalities in the lungs before a person shows COVID-19 symptoms, alerting doctors before there’s a true emergency and hopefully preventing hospitalizations.By monitoring heart health, users can also get a better sense of their stress levels.“Understanding the level of stress you’re getting is important, as important as the other physical health monitoring," said Moon. Moon was already working on the technology before the pandemic to monitor other health conditions like asthma, COPD, sleep apnea, and lung cancer. But COVID-19 accelerated and pivoted the focus of the research.The team hopes to license the technology to a company that can produce and sell the device, likely at a price of around a few hundred dollars.“Seeing that would be a tremendous joy for me," said Moon.Moon is hopeful the wearable could be sold next year and that it will continue helping patients after the pandemic is over, delivering a sense of control in a time of such uncertainty. 1740

San Diego City Council Tuesday night unanimously passed the location of a high-pressure underground pipeline to move sewage from San Diego's Morena treatment plant to a facility in Miramar. Residents say they're concerned the pipeline could break, wreaking havoc on the area. "Our concern is if that line was ruptured, bnecause it's under so miuch pressure, that it would spew raw sewage into the environment," said Ruth DeSantis, a longtime U.C. resident who heads the area's community foundation. DeSantis added that neighbors are concerned over traffic, noise, property values, and even smells seeping out of vents. There's a middle school, park, and hundreds of homes nearby. The city says it took various measures to minimize health and safety hazards, although some impacts like noise and traffic are unavoidable during construction.San Diego spokesman Jerry McCormick added that sewage geysers would not be possible under the pipeline system."Unlike a potable water system, where there are multiple loops to provide continuous pressure and in time of a rupture must be isolated by multiple valves, often times creating large releases of water, this system will not operate like that," McCormick said. "Instead, if there is a rupture, we can shut down the pumps and the flow will come to a very abrupt and quick stop."Community groups in University City are now teaming up with those in Clairemont to fight the project."We can put everything in Clairemont and Clairemont is sleeping, and I just wanted to say, that's not right," said Roseline Feral, of the nonprofit Clairemont Town Council. The city is aiming to have about a third of its water supply be reclaimed water by 2035. That would help combat shortages and price increases.                                       1922

SAN DIEGO, Calif. (KGTV) - A third gender option will be available for California drivers licenses and ID’s starting in 2019. The law, SB 179, was signed by Governor Jerry Brown in October. It will allow people to apply for a ‘non-binary’ gender marker if they do not identify as either male or female. “For me, it was surprising to see this change,” said Al Johnson, a transgender activist and member of Trans Family Support Services. Johnson is non-binary and uses pronouns they/them. But with that surprise, came excitement. “Not only does it mean we’re being recognized by society and the people around us but were also being recognized by government entities as valid and real people,” they said. Johnson says they know people who plan on changing their gender to non-binary, but so far, they have not decided to do it on their own license. “I’ve definitely considered it, but in the end I don’t think I’m going to,” they said. “I just came out to my parents and in my personal life I’m trying to navigate that.” The DMV’s website is encouraging those who want to apply for the change to schedule an appointment as early as January 2, 2019. 1154
