SAN DIEGO (KGTV) People across California will soon be able to use an app to notify or find out if they have been exposed to COVID-19.The CA Notify system was launched on the campus of UC San Diego in September. Monday, Governor Gavin Newsom announced the tool would be available on Google and Apple devices statewide beginning on December 10th.Dr. Christopher Longhurst, Chief Information Officer for UC San Diego Health, says the tool helps stop the spread of the virus on campus."While San Diego case rates have surged from 3 to 6 percent, our campus has fortunately remained a safer place with our students and employees testing positive at less than 1 percent," said Dr. Longhurst.Philip Tajanko is a freshman at UCSD. He signed up for the app shortly after arriving on campus in September."I figured that I might as well download the app just in case," said Tajanko.Tajanko tested positive for the virus in October."Outside of the people I directly informed by giving them a phone call or text, it did give me some peace of mind knowing that I could just send out this blanket alert that would notify anyone that I had been in contact with but don't have their phone number," said Tajanko.The system uses smartphone technology when a users' phone is within close proximity to another user for an extended period."You're not going to get an exposure unless your phone is within 6 feet of someone else's device for greater than 15 minutes cumulatively," said Dr. Longhurst.The governor stressed the app is opt-in, 100% private, secure, and does not track location.It has been effective. Even if we don't have tens of millions of people participating in this program, the more people who opt-in, the more effective it can be," said Governor Newsom. 1759

od safety and the coronavirus diseaseOn Monday, the FDA approved Hologic's clinical trials for Emergency Use Authorization. Since then, they have shipped hundreds of thousands of their test kits to their clients, including local hospitals, laboratories, public health systems, and the Department of Defence, for testing military personnel.“What you’ll see is something like this," Thornal held a small vile. "This is just a small vile that has a nasal swab that looks like a Q-tip. And that will be put up your nose, and they’ll put it into a vile this and send it off to the lab. Their machines can test up to 1,000 samples in a day, and results come out in about three hours. RELATED: UC San Diego, manufacturers increase COVID-19 testing capacityUnlike early manual-style tests, Thornal said Hologic's automated kits take out the possibility of human error. Plus, everything from research and development to production happens here. “The test was invented by scientists that live here right here in San Diego," Thornal. "And right now, our operations team right here off of Mira Mesa Boulevard, that’s where all of this manufacturing is occurring, is shipping out from here to the globe.”Hologic said their goal is to send out 600,000 test kits per month, worldwide by April. 2416

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)- For weeks, the pandemic left nursing students at CSU San Marcos in limbo when it came to completing their graduation requirements. Now, thanks to the county, the students can get their clinical hours.When the pandemic hit in March, nursing students were forced out of public health facilities to get their hands-on experience for their classes.“We didn’t know when we were going to go back, and it was halfway through the spring semester,” says nursing student Winter Minton.Minton will be graduating from CSU San Marcos in the spring.The nursing student says for weeks, students were unsure about how they would obtain their clinical hours. A total of 135 hours are needed for two classes.“When we were ready to go back, the county was not willing, ready to have nursing students on site at all,” says Course Coordinator Madelyn Lewis.In August, the county opened a COVID-19 testing clinic on campus and allowed nursing students to work on-site. The students assist patients with self-administered COVID tests while wearing full protective gear.“Not only does it benefit us, but it benefits so many people,” says Minton. “I heard people driving all the way down from Irvine or Fullerton just to get the exam done.”Minton says the walk-in clinic sees more than 300 patients a day.The testing site is open to the public seven days a week. 1363

SAN DIEGO - San Diego photographers are taking advantage of the serene and luminous glow of the surf this week.Eerie neon blue waves have been seen against San Diego's shore this week, creating some rare photo opportunities. The phenomenon is created when a red tide, which is algae bloom filled with phytoplankton called "dinoflagellates," rolls off waves onto or near the shoreline.The organisms react with a bioluminescent chemical reaction when jostled as a way to warn predators, to lure prey, or communicate within their species. The blue glow can be created by a simple step in the water or crash of a wave.IN SAN DIEGO...The current red tide is being caused by massive numbers of dinoflagellates including "Ceratium falcatiforme" and "Lingulodinium polyedra," according to the Scripps Institution of Oceanography at UC San Diego.The Scripps Institution of Oceanography at UC San Diego is not affiliated with The E.W. Scripps Co., the parent company of this station. Researchers do not know how long this current red tide will last or "the full spatial range of the bloom." In the past, blooms have lasted anywhere from a week to a month or more.San Diego's last red tide event in September 2013 lasted one week, while the previous one in October 2011 lasted a month, according to researchers. Previous ones have lasted even longer.Monday's event was captured from La Jolla to Encinitas. Scripps recommends viewing the marine event from a dark beach at least two hours after sunset, though visibility is not guaranteed.IS IT HARMFUL?...In some areas, a red tide can be toxic to local marine life. In California, the majority are not caused by species that produce toxins, such as domoic acid, according to researchers. However, it's still best to be cautious around the bloom.The Southern California Coastal Ocean Observing System at Scripps samples the water for potential harmful algal toxins weekly.Red tides are unpredictable events and do not always give off bioluminescence, Scripps said.BUT WHY IS IT RED?...The red coloration is due to the high number of organisms in the water. During the day, organisms will swim to the surface to soak in sunlight. Each cell contains a little sunscreen that gives off the color, according to Scripps.When these organisms gather at the surface for sunlight, they can create an especially intense red.Researchers say a combination of physical, chemical, and biological factors are the driving forces behind allowing red tides to form. 2586
