SAN FRANCISCO (AP) — San Francisco Bay Area police say two teens have admitted to starting a grass fire that scarred an iconic hillside amid a scorching heatwave and dangerous fire conditions. South San Francisco police said a brush fire spotted Friday around noon on “Sign Hill” grew quickly due to hot and windy conditions. Crews contained the fire hours later with no injuries and no structures lost but residents were temporarily displaced. Officials say an alert resident spotted two teen boys, ages 14 and 16, leaving the area where the fire started.It has been a disastrous wildfire season in California. 619

Sen. Elizabeth Warren has released the results of a DNA analysis showing she has distant Native American ancestry, which could pre-empt further questions and attacks should she run for president in 2020.Warren first faced scrutiny for her purported Native American heritage during her 2012 Senate race. But President Donald Trump has revived and amplified the controversy as he eyes Warren as a possible rival, frequently mocking her with the nickname "Pocahontas."But Warren now has documentation to back up her family lore, thanks to an analysis performed by Carlos Bustamante, a professor of genetics at Stanford and adviser to Ancestry and 23 and Me.In a rollout video about Warren's heritage, the Massachusetts Democrat is seen sitting behind a laptop as she calls Bustamante. 789

SAN MARCOS, Calif. (KGTV) - Several people in a San Marcos gated community have reported being targets of package thieves, according to one victim who spoke with 10News. The Sheriff's Department is looking at surveillance video, which appears to provide several leads.Mikayla Manos says a package was sent to her home on Almond Drive Friday.  Manos is a mentor for foster children. The package contained the personal items of one of those children, which she was asked to deliver to him.  When Manos arrived home, she did not see the package.Manos checked with her next-door neighbor, who has a surveillance camera. Video from Friday afternoon shows a girl walking past Manos' home. She turns and points toward Manos' porch and can be heard saying "get it".The video shows what appears to be a boy picking something up from Manos' porch, although the package cannot be clearly seen from the camera angle. At least two voices can be heard off camera. One is heard saying "I can't wait to wear these to school tomorrow." Manos says clothes are among the items stolen.Manos says she knows of at least three other neighbors who were victims.  10News spotted an empty Nordstrom bag ripped open on one neighbor's porch, while another neighbor tells 10News someone stole items from his garage when he briefly left it open around the same time.Several package boxes were found dumped nearby, including Manos'. Some of the foster child's items were recovered, but many remain missing. 1498

Scientists at the University of Nevada, Reno School of Medicine (UNR Med), led by its Nevada State Public Health Laboratory (NSPHL) are studying a likely case of COVID-19 reinfection.Forty-eight days after testing positive for SARS-CoV-2 in April 2020 and after testing negative consecutively twice, a Washoe County, Nevada patient tested positive again, in June.The patient had tested negative on two separate occasions in the interim. The genomes of the patient’s virus samples were sequenced in April and June, displaying significant genetic discordance between the two cases, implying the patient was infected twice.“We examined the genomic material of the viruses and samples to investigate this, says NSPHL Director Mark Pandori. “It is just one finding, but it shows that a person can possibly become infected with SARS-CoV-2 a second time.”To solidify confidence in the case, Pandori and the research team partnered with the Washoe County Sheriff’s Office Biology Unit to conduct identity testing on the specimens and lab samples evaluated in the study to verify the specimens were from the same person.Embedded in the genomic material of SARS-CoV-2 is a detailed code that Pandori says may provide insight to a better understanding of this virus.“A virus has a biological genome like all living things. Since March, the NSPHL has analyzed the genomic RNA of approximately 200 positive COVID-19 samples from Nevadans who have tested positive for COVID-19,” said Pandori. “The power of genomic information could turn the tables in the fight against the coronavirus.” The information is shared to a world-wide database known as “GISAID”,” alongside the work of thousands of researchers.According to Pandori and the NSPHL-led research team, reinfection cases are a potential warning sign that it is possible to catch COVID-19 more than once, and with unpredictable severity.“If reinfection is possible on such a short timeline, there may be implications for the efficacy of vaccines developed to fight the disease. It may also have implications for herd immunity,” says Pandori. “It is important to note, that this is a singular finding. It does not provide any information to us with regard to the generalizability of this phenomenon.”Herd immunity depends on the theory that after natural infection, our immune systems will collectively protect us as a community from reinfection and further spread. There are currently many more unknowns than knowns about immune responses to COVID-19. “After one recover from COVID-19, we still do not know how much immunity is built up, how long it may last, or how well antibodies play a role in protection against reinfection,” says Pandori.”While research and scientific advancements continue to build, Pandori says the hard work of fighting this pandemic together will continue through the use of facial coverings, hand-washing, social distancing, as well as wide-scale testing, contact tracing, and isolation of new cases.“This is a novel disease. We still have a steep learning curve ahead and lots of work to do, especially as inconvenient truths arise,” says Pandori.The NSPHL team are publishing their COVID-19 reinfection findings. Their report is publicly accessible on the SSRN preprint server, at https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3681489. This story was first reported by KTNV in Las Vegas, Nevada. 3384

SANTA ANA, Calif. (AP) — The owner of some 100 local car washes and gas stations in Southern California has been charged with failing to pay minimum wage and overtime to some 700 workers.The Orange County Register reports prosecutors say Vahid David Delrahim and his managers ordered the workers, nearly all Latino, to arrive early, but the workers were not allowed to clock in until customers arrived. When business slowed, they had to clock out but still remain on duty, waiting until more customers turned up. The result: numerous hours without pay.The U.S. Department of Labor is seeking at least million in back wages and damages.RELATED: Home Depot and Lowe's training the next generation of construction workersDelrahim's lead attorney, Rebecca Aragon, and her team call the government's claims "frivolous, vexatious and unreasonable," arguing that Delrahim was "without sufficient knowledge to admit or deny" the allegations.Prosecutors also cite the intentional "wanton destruction" of evidence. 1020
