LONG BEACH (CNS) - For thousands of years, millions of tiny white abalone snails lived along the California coast.Now facing extinction, the white abalone will be getting a major boost toward survival this month, thanks to a breeding program spearheaded by marine organizations across the state, including the Aquarium of the Pacific in Long Beach.In mid-November, researchers from the aquarium, the National Oceanic and Atmospheric Administration, the UC Davis Bodega Marine Laboratory, the Bay Foundation, Paua Marine Research Group and state Department of Fish and Wildlife will be releasing white abalone into the wild at a series of undisclosed locations across Southern California.RELATED: Dog swept out to sea rescued, owner asks for more signage"This is a historic moment, as a species once on the brink of extinction may finally have a chance to rebound," said Sandy Trautwein, vice president of animal husbandry at Aquarium of the Pacific. "This is important not just for white abalone, but for the entire marine ecosystem off Southern California."Researchers are withholding the locations of the planned releases, hoping to give the white abalone the best chance at successfully settling into their new homes. The white abalone were actually placed underwater at their release locations last month, but they remain inside holding boxes."Natural recovery is not occurring fast enough or at all for this species to rebound on its own," said Melissa Neuman of the NOAA National Marine Fisheries Services' Abalone Recovery Program. "Fishing and other human activities brought white abalone to the brink of extinction, and now it is our responsibility to recover the first federally protected marine invertebrate."RELATED: Video: Rare blue whale with calf spotted off San Diego coastThousands of the white abalone have been bred through the program. Aquarium of the Pacific officials noted that when they joined the program in 2008, only 75 white abalones existed in managed care.The once-teeming population of white abalone was decimated over the decades by overfishing and low reproduction rate, according to the NOAA. Recent surveys indicated that the population dropped by about 99% in Southern California since 1970s.The white abalone was officially listed as a federally endangered species in 2001 -- the first marine invertebrate ever to make the list.NOAA officials said that without intervention, the remaining population would likely continue to decrease by 10% a year. 2493

LOS ANGELES (AP) -- California authorities sent a cellphone text alert to two major regions of the state to tell millions of people that the coronavirus is spreading rapidly and ask them to stay home except for essential activities.The Tuesday noon blast to the state-designated 11-county Southern California region -- which includes San Diego County -- and 12-county San Joaquin Valley region was sent by the Office of Emergency Services.The text also urged people to wear masks and physically distance.RELATED: New COVID-19 stay-at-home order takes effect in San Diego CountyBoth regions came under increased restrictions this week after the total capacity of hospital intensive care units dropped below 15%.The restrictions will remain in effect for at least three weeks. 782

LOS ANGELES (AP) — "The Fresh Prince of Bel-Air" star Alfonso Ribeiro has dropped a lawsuit against the makers of the video game "Fortnite" over its use of the "Carlton" dance he did on the show.Ribeiro's lawyers filed documents Thursday in federal court in Los Angeles saying he's voluntarily dismissing the suit against North Carolina-based Epic Games.No reason was given, and Ribeiro's lawyer did not immediately reply to a request for comment.The actor had already dropped a similar suit against Take-Two Interactive, makers of the video game NBA2K16.The suits received a serious blow last month when federal officials denied Ribeiro a copyright of the "Carlton."Ribeiro's nerdy, arm-swinging dance, usually to Tom Jones' "It's Not Unusual," was popularized through his character, Carlton Banks, on the 1990s sitcom. 828

LOS ANGELES (CNS) - USC health officials Monday reported an "alarming" spike of 43 coronavirus cases confirmed in off-campus housing facilities, along with 100 students in quarantine due to possible exposure to COVID-19.According to Dr. Sarah Van Orman, head of USC Student Health, 14 cases were identified through general population testing among students not showing any symptoms, while 29 more were confirmed through contact tracing and testing of people showing symptoms or who were exposed to the illness."Los Angeles is at a critical juncture in public health," Orman wrote in a Monday virus update. "While no students have been hospitalized to this point, we all need to work together to protect those in our community who may be at higher risk of severe disease and prevent serious health outcomes for all. Your role in containing, or conversely, accelerating the rapid spread of COVID-19, can mean the difference between safely returning to a modified `new normal,' or having a prolonged period of remote-only academic experience and closed facilities."She urged students "in the vicinity of USC, especially those living with housemates or suite-mates," to get tested weekly through the university's "Pop Testing" program. Orman also noted that the spike in cases occurred despite restrictions on on-campus instruction and activities."It appears highly unlikely current conditions will significantly change in the weeks ahead," Orman said. "The county may grant a small number of exceptions for specific classes and other activities that cannot be delivered in a virtual setting, however, those decisions have not yet been made. Therefore, we continue to strongly discourage students from returning to the campus area until further notice."... For students who remain on or near campus in shared living arrangements, we strongly advise you to act with caution and strictly follow all guidelines for physical distancing -- six (feet) -- avoiding gatherings with other(s) outside your home, wearing face coverings around others to protect against respiratory droplets, and proceed with high adherence to hand hygiene and frequent surface contact cleaning." 2171

LONDON (AP) — Some public health experts are criticizing the U.S. for securing a large supply of the only drug licensed so far to treat COVID-19. The U.S. government announced this week that it had an agreement with Gilead Sciences to make the bulk of their production of remdesivir available to Americans for the next three months. A senior lecturer at the University of Sussex called the U.S. agreement “disappointing news." Until now, the California-based Gilead had donated the drug. That ended Tuesday and Gilead has set the price for new shipments. Gilead is allowing generic makers to supply the drug to poor or middle-income countries at much lower prices. 672
