SAN FRANCISCO (AP) -- If you haven't been wearing a face mask while taking an Uber, you may be required to take a selfie to prove you are ready to don one the next time you summon a driver on the world's largest ride-hailing service.The mask verification rules rules announced Tuesday expand upon a similar requirement that Uber imposed on drivers in May to help reassure passengers worried about being exposed to the novel coronavirus.The additional safety measures are part of Uber's efforts to rebuild a service that has saw ridership plunge by 56% in the company's most recent quarter. 597

SAN DIEGO (KGTV): A new study shows that young adults are seeing a spike in deaths from liver disease related to binge drinking. It's especially dangerous in California, where high alcohol content drinks are popular.The study, published this month in the British Medical Journal, says that the number of 25- to 34-year-olds who died annually from alcohol-related liver disease nearly tripled between 1999 and 2016, from 259 in 1999 to 767 in 2016, an average annual increase of around 10 percent.It cites binge drinking as a leading cause, because of rising rates of alcohol consumption between 2002 and 2012.It's especially bad in California, which the study says was among the top five states for those types of deaths.Local experts say the kind of alcohol we drink may be to blame, as craft beers tend to have higher concentrations of alcohol."If someone was having highly concentrated alcohol, then they're consuming more drinks per hour," says Dr. Rohit Loomba, with the UC San Diego Health Liver Center. "That will have detrimental effects on the liver, for sure."The CDC recommends no more than 1-2 drinks per day for "moderate" drinking. Binge drinking is defined as 4 or more drinks over 4-6 hours. Loomba says you may hit the "binge" point in fewer drinks if what you're having is stronger.For example, a Bud Light has just 4.2% alcohol by volume. Craft beers often have 6% or higher, so one craft beer may be as much as 2 or 3 other drinks."That quantity of alcohol intake over years definitely will contribute to higher risk for liver disease," says Loomba.He says people should ask themselves four questions to determine if they are drinking too much:1. Have you ever cut down on drinking? 2. Would you be annoyed if somebody asked you to cut down on drinking? 3. Do you feel guilty after drinking excessively over a weekend? 4. Do you need an "eye-opener" in the morning to get to work?Dr. Loomba says if you answered "yes" to 2 or more of these questions, you should talk to your doctor to discuss treatment.He also says obesity combined with alcohol can lead to more severe liver problems and even death. People with diabetes or who are overweight multiply their risk of the disease."If you're obese, you not only should restrict your alcohol, but you should try to lose some weight as well," says Loomba.The study says the financial crisis may have led to more binge drinking in the past decade, as young adults turned to alcohol to cope with financial stress. Researchers found the rise in alcohol-related deaths overlaps with rising rates of binge drinking from 2002 to 2012 observed across much of the U.S.The good news, according to the study, is that many liver diseases are preventable and reversible."Once you stop alcohol use, you can reverse complications related to it in the majority of cases," says Dr. Loomba. 2882

SAN DIEGO (KGTV) Chicano artists and activists gathered to voice their concerns about two more murals getting torn down during construction on a local school, one week after the first mural was destroyed.The San Diego Unified School District is working on upgrading Memorial Preparatory school in Logan Heights. Part of the upgrade involves tearing down buildings and walls, and on some of those walls are decades-old murals painted by local Chicano artists. The murals all celebrate the history and culture of the local area.Wednesday, Sept. 30, the artists gathered with a group outside the school and asked to save the murals. Moments later, the first mural was destroyed. A spokesperson for the district said that building could not be saved because it had asbestos.The advocates expressed concern over that statement, saying if the asbestos was really that bad, the construction workers should not have let it collapse the way it did, allowing dust to spread into neighboring homes.RELATED: Barrio Logan artists upset about destruction of historic muralOne week later and the artists gathered again in front of the school, this time saying there are two more murals inside the school they want to save. They said to their knowledge, the buildings these murals are painted on are staying up and these areas do not have asbestos, but certain parts are being torn down, including where the murals are. They’re asking the district to save these murals, offering to supply the funding and labor needed to move the artwork.“What we’re saying is we have the resources we have the will and we have the passion to go forward with the removal. So it’s not that it can’t be done, it’s that we’re not being allowed our rights to preserve them for the entire community,” a representative from the group said.KGTV spoke to a representative from the district Sept. 30, who said they did not want to take the murals down but had to for safety reasons due to the asbestos. They also mentioned the construction will benefit the students in the long run. The district could not be reached again the following week, so KGTV was unable to ask why the other two murals cannot be saved. 2176

SAN DIEGO, Calif. (KGTV) - With car horns blaring, cellphone video captured a fight breaking out at a busy intersection in San Diego near Montgomery High School.The incident played out at Palm Avenue and Beyer Way - just feet from the high school - as school let out Friday afternoon. In the crosswalk, there was a flurry off punches. A teen in a hoodie is recorded battering another student on the ground. Some other teens joins the fray and more punches are traded."It's stupid. Why have a fight so dramatic like that? It could cause a car accident," a student told 10News. We are not naming the student at the request of their family.The student doesn't know what sparked the fight, but says those involved were juniors. The student told 10News this was the third big fight on campus this year. "Just make us look bad. Students should set a good example for our school," the student said.There were no accidents, but some of those drivers did get out of their cars. A witness tells us some tried to stop the fight. In the now-viral video, a crowd of people spill across the crosswalk. The melee lasted more than 20 minutes before it broke up. Police arrived but did not make any arrests.Janet Paz, a mother of two students at the school, says it sends a bad message."Makes me feel worried that kids aren't safe in school," said Paz.A spokesperson with the Sweetwater Union High School District says they believe they've identified the three-to-five students involved and are mulling possible discipline. Part of the investigation will include determining the cause of the fight and addressing any campus-wide issues. 1628

SAN FRANCISCO (AP) — A federal count shows the number of homeless people increased by double-digit percentages in three San Francisco Bay Area counties over two years as the region struggled to tackle the growing problem, including 17% in San Francisco and 43% in the county that includes Oakland.More than 25,000 people were counted as homeless during an overnight tally conducted in San Francisco, Alameda and Silicon Valley's Santa Clara counties in January. Detailed reports are expected later this year."The initial results of this count show we have more to do to provide more shelter, more exits from homelessness, and to prevent people from becoming homeless in the first place," said San Francisco Mayor London Breed.The San Francisco Bay Area is grappling with a homelessness crisis driven in part by too little housing stock and a raring tech economy that has widened the inequity gap. In San Francisco, the median price of a two-bedroom home is .3 million and a family of four earning 7,400 a year is considered low income.The homelessness point-in-time count is conducted every two years and is required by the U.S. Department of Housing and Urban Development. Los Angeles is expected to release its figures on May 31.Homelessness is an issue that has riven the Bay Area for years, with elected leaders pledging to do more to address it. However, controversies continually erupt over where to build homeless shelters. Residents of a wealthy San Francisco neighborhood, for example, are fighting the city's plans to erect a shelter along the waterfront Embarcadero area that is popular with tourists.In San Francisco, the number of people who were not sheltered surged 20% to nearly 5,200, driven largely by people who are living in cars. In Santa Clara County, which includes the city of San Jose, the homeless population increased 31% to about 9,700 this year. Alameda and San Francisco counties each counted more than 8,000 homeless.California Gov. Gavin Newsom has proposed giving cities and counties up to 0 million to build and expand emergency homeless shelters. He's also proposing million to help public colleges and universities house homeless students and million for legal aid for people facing eviction. 2252
