SAN FRANCISCO (AP) — A lawyer for the man who styled the hair of U.S. House Speaker Nancy Pelosi says he believes she was set up when she went to a San Francisco salon that wasn't permitted to have indoor services because of the coronavirus pandemic. Pelosi is facing backlash after Fox News Channel aired footage showing the speaker walking through the salon without a mask on. But a lawyer for the stylist says the owner gave permission for the appointment and made “vitriolic and incendiary comments" about Pelosi. Messages seeking comment from the owner weren't immediately returned. 595

San Diego (KGTV)- Hygiene continues to be a struggle for those living on the streets, especially during the pandemic. Non-profit Duwara Consciousness is helping the homeless gain access to a hot shower.The non-profit uses its food trailer to feed the homeless. On average, they provide about 1,500 meals per week."Our distribution network currently runs as far as San Ysidro and as far north as Carlsbad," says Harisimran Khalsa.But as we continue to experience the COVID-19 pandemic, Khalsa says access to a hot shower was limited for those in need. This prompted her and partner, Davinder Singh, to move forward with their idea of a shower trailer."Hygiene access is just not as frequent. So you do end up coming down with more bugs, more viruses," says Khalsa. "We think that this is really a time when we have to focus on hygiene for our homeless population."The shower trailer contains seven individual stalls, including one that is ADA compliant."It's really critical for our guests that they have a secure environment in which to shower."Khalsa says about 20 people can use the shower per hour. The stalls are cleaned after each use following CDC guidelines.The trailer comes equipped with sinks for people to wash their hands, shave or brush their teeth. It also has laundry services. The non-profit partners with other organizations to provide space and water.Duwara Consciousness plans to launch the shower trailer on Friday officially, but so far, they say users have been grateful for a simple hot shower. 1525

SAN FRANCISCO (AP) — Major changes to the way people vote has election advocates on edge as Californians cast ballots in the Democratic presidential contest and other primary races. The “Super Tuesday” primary in the country's most populous state comes amid changes aimed at expanding voter participation, including new voting equipment and vote centers that are replacing polling places in some counties. Those changes may confuse some people. There are fears California might end up with a mess much worse than Iowa, where the Democratic Party couldn't declare a winner for several days. Advocates say voters are hanging onto their ballots, which will likely mean long lines Tuesday. 694

SAN DIEGO (KGTV)- Several trailers were set up at El Toyon Park in National City and will become a study site for a COVID-19 vaccine clinical trial, ran by UC San Diego.Drugmaker Johnson & Johnson is looking to enroll participants worldwide for phase three of its Janssen trial, including here in San Diego.UCSD will recruit the majority of the participants.The trial was scheduled to get underway on October 7th, but UCSD researchers now say they're looking at Friday as a start date."We hope to enroll about 2,000 people in San Diego, the study will be enrolling 60,000 people internationally," said Dr. Susan Little, a UCSD professor of medicine and principal investigator for the trial. "Eight Department of Defense trailers form the basis of our permanent vaccine site, vaccine clinic, in National City."Little said this will be a randomized, double-blind, placebo-controlled study to determine the vaccine's safety and efficacy."Does it reduce the frequency of COVID infection overall or the severity of COVID infection among study participants?" she said.Little said there is already a lot of data available from the past."This is the same vaccine vector that has been used for many other infectious diseases like HIV, Zika, Ebola," she said.Although the trial is open to all San Diego County residents who qualify, she said the focus would be on recruiting residents from the South Bay, which is why the clinic was set up in National City, instead of UCSD's La Jolla or Hillcrest locations."Communities of color have been harder hit in the sense they have higher rates of hospitalization, and many of them have higher rates of death, our hope was by placing the vaccine trial in a community that has higher rates of infection we could reach a more highly impacted community," she explained. "Those are populations that we hope will have a greater potential benefit from this vaccine."After concerns were raised over another trial that was later put on hold, UCSD worked with the Chicano Federation to ensure South Bay residents get the information they need to make an informed decision if they want to participate."We are putting safety as paramount for these studies, no study is going forward unless we are confident about the safety of the vaccine," said Little.The Janssen trial will be the third for UCSD to join. The Moderna trial is currently underway, and the AstraZeneca trial is on a national pause. 2430

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
