SAN DIEGO (KGTV)—  They’re convenient. They’re trendy. But some are now saying the popularity of dockless bikes is problematic. Whether you are a local or tourist, there is something magical about Little Italy that propels you in. “The microclimate is great, it’s attractive and beautiful,” Marco Limandri of the Little Italy Association said. RELATED:  386

SAN DIEGO (KGTV)-- Beginning Thursday, wearing masks has become a state mandate. A new study out of the University of California, San Diego, suggests the best way to curb the spread of coronavirus is by wearing a mask.In a UCSD campus-released article titled "To wear a mask or not, is not the question; Research indicates it's the answer," Chemistry Nobel Laureate and UCSD Professor Mario Molina shows the data does not lie."Let's work with the scientists," Molina said. "Let's work together with society!"RELATED: San Diego County exceeds community outbreak trigger, forcing pause on future reopeningsHe and a team of scientists at CALTECH and Texas A&M looked at the world's three COVID-19 epicenters: Wuhan, Italy, and New York City. They studied each area's attempts to mitigate the spread of COVID-19, including shelter in place, social distancing, and wearing facial coverings.Their study showed, in Wuhan, where mask-wearing is part of the culture, the spread was relatively slow. But in Italy, even after the lockdown, positive cases continued to climb. Additionally, despite the stay-at-home order in New York City, numbers continued to rise.A pivotal point of the study was when they looked at the numbers in Italy and New York after their respective mask mandates went into effect on April 6, 2020, and April 17, 2020. It was only then that the spread of viral air particles slowed drastically.RELATED: California requiring face coverings for most indoor areas"It changes. It's no longer straight. It goes downwards," Professor Molina said, referring to the curve on the bar graph.The professor reminds people that this does not mean to ignore all the other health measures."We are not saying using masks is the only thing that matters, no," Professor Molina said. "What we have in the paper is, everything is added to social distancing and to quarantine."RELATED: Mayor releases outdoor dining proposal in Little ItalyProfessor Molina says California's new facemask mandate is similar to government regulations on air pollution but on a much personal scale. In this case, you are the car, and COVID-19 is pollution. He says he is hopeful that with the mandate, the numbers in California will decline."We tell people, 'Hey, it's a good idea to wear face masks. You protect your family, and you protect yourself!'" Molina said.Molina says a secondary research paper analyzing mask mandates in different states will be published in the coming weeks. 2472

SAN DIEGO (KGTV): The San Diego Sheriff's Department has a new tool to help keep deputies safe as they fight the war on drugs.The department just bought 15 TruNarc devices. The hand-held scanners can detect and identify drugs without the deputies having to come into physical contact.Previously, to determine what kind of drug was present at a crime scene, law enforcement would have to scoop a small amount into a kit for testing. The TruNarc uses laser technology to scan through plastic bags.This technology has become increasingly important with the rise of drugs like Fentanyl. Just a microscopic amount can cause an overdose, which has made first responders wary of handling it.The TruNarc can identify more than 200 different drugs and takes less than 2 minutes to complete the scan and give a presumptive result.San Diego Sheriff's Deputies used it earlier this month when they encountered an unconscious man in San Marcos. He was covered in white powder. Deputies called for the scanner and found the powder was Fentanyl. They called for a hazmat team to clean the scene. Officials with the department say the device likely saved the man's life, as he was able to get the medical help he needed. They say it also may have saved the officers, who didn't have to touch the man or the powder until after the scene had been made safe.The devices cost ,400 each. A grant from the Honorary Deputy Sheriff's Association helped pay for them. One has been given to each sub-station around the county. There is also one at every jail and another at the High-Intensity Drug Trafficking Area office. 1617

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
