LOS ANGELES (AP) — California environmental officials say a popular agricultural pesticide they say has been linked to brain damage in children will be banned after next year under an agreement reached with its manufacturer.Under the deal announced Wednesday, all California sales of chlorpyrifos will end on Feb. 6, 2020.Farmers will have until the end of 2020 to exhaust their supplies.The pesticide is used on numerous crops in the nation's largest agriculture-producing state, including alfalfa, almonds, citrus, cotton, grapes and walnuts.State regulators say the pesticide has been linked to health defects in children, including brain impairment.Officials say they are budgeting million to help manufacturers develop a safer alternative.The pesticide's manufacturer, Corteva Agriscience, says it reached the agreement "in the best interests of the affected growers." 884

LOS ANGELES (CNS) - Downward trends in coronavirus cases and testing-positivity rates could allow Los Angeles County to move into the next tier of the state's economic-reopening matrix by sometime in October, according to the county's public health director, but pending Labor Day numbers could potentially thwart that move.The county is in the most restrictive, or "purple," level of the state's four-tier virus-tracking roadmap. The county already has a low enough seven-day average testing positivity rate -- around 3.2% -- to move to a less-restrictive tier, but average new case numbers are still too high, currently averaging 8.1 cases per 100,000 residents. The state threshold for advancing to the "red" tier is seven cases per 100,000.However, Public health director Barbara Ferrer said Wednesday numbers in all categories have been trending downward over the past six weeks following a spike seen after the Fourth of July holiday weekend."If we don't see a surge in cases and hospitalizations associated with activities over Labor Day and we continue to reduce our rate of community transmission over the weeks ahead, we could enter tier 2, which is a less restrictive tier, sometime in October," Ferrer said.Health officials have said repeatedly they will not consider any more business reopenings in the county until at least late September, after determining if virus cases and hospitalizations increase following the Labor Day holiday weekend -- the way they did after Memorial Day and the Fourth of July.If the county gets its average new case numbers below seven per 100,000 residents, and maintains that level for two weeks, the county will be able to move into the state's "red" tier. That would allow more businesses to reopen, including potentially movie theaters and gyms, as well as school campuses for in-person learning.Ferrer said the county is now seeing its lowest average testing- positivity rate of the pandemic."Last week, we saw the lowest positivity rate to date, at around 3.4%," she said. "This means that almost 97% of the tests that people took for COVID-19 ended up being negative. Just a month ago, in mid-August, this rate was around 5%. So we're happy to see the progress that we've made and we're very much hoping that this number continues to decrease."She again warned, however, that the impact of the Labor Day holiday weekend has yet to be borne out in case numbers, since the virus has a 14-day incubation period. She also said upcoming fall and winter holidays, including the start of Rosh Hashanah this weekend, could lead to setbacks if people become lax about social distancing and other preventive measures."The autumn and winter months are filled with special times that we all are looking forward to," she said. "There's many secular and religious holidays that we usually celebrate by spending time with our friends and extended family members. And the pandemic has been difficult and frustrating in many ways, including placing limits on how we can celebrate safely. I do encourage all of us to think now about how we might want to modify our plans so we can share the joy of the holidays while reducing the risk of transmitting a dangerous and sometimes deadly virus."She and the county's health services director, Dr. Christina Ghaly, urged people to get a flu shot, noting that as flu season arrives, people who contract both influenza and COVID-19 may be susceptible to severe illness.The county on Wednesday reported 31 coronavirus-related deaths, although one of those fatalities was actually announced Tuesday by health officials in Long Beach. Long Beach announced two additional deaths Wednesday afternoon. The total number of fatalities in the county stood at 6,305 as of Wednesday.The county also announced 1,148 newly confirmed cases, while Long Beach added 40 cases and Pasadena reported six, lifting the cumulative total since the start of the pandemic to 256,194.There were 804 people hospitalized due to COVID-19 in the county, up slightly from Tuesday. Ghaly noted that the sharp downward trend seen in hospitalizations over the past month appears to have slowed or leveled off. But hospitalization numbers till remained at dramatically lower levels than they were a month ago.Ghaly said overall testing numbers over the past week were down, thanks in part due to closures of some testing centers due to poor air quality caused by the region's wildfires. She said some testing sites have two-thirds of their appointment slots available, so she encouraged anyone with symptoms of the coronavirus or who thinks they may have been exposed to get tested. 4630

LONDON (AP) — The World Health Organization is acknowledging the possibility that COVID-19 might be spread in the air under certain conditions.This comes after an open letter from more than 200 scientists published this week urging the agency to do so.WHO has long dismissed the possibility that the coronavirus is airborne except for certain risky medical procedures, such as when patients are first put on breathing machines.But it noted on Thursday that studies evaluating COVID-19 outbreaks in restaurants, choir practices and fitness classes suggested the virus might have been spread in the air. 609

LONDON (AP) — Cinema chain Cineworld says it is considering closing all its movie theaters in Britain and the United States, after the postponement of the new James Bond film left a big hole in schedules. Cineworld Group PLC owns 543 Regal cinemas in the U.S. and 128 Cineworld venues in the U.K. and Ireland. It said Sunday it was "considering the temporary closure of our U.K. and U.S. cinemas, but a final decision has not yet been reached." The statement came after the Sunday Times reported that Cineworld's U.K. theaters will shut in the coming weeks. The release of James Bond thriller "No Time to Die" has been delayed from November until April 2021 because of the effect of the coronavirus pandemic. 716

LOS ANGELES (AP) — A California dam could fail during an extreme storm and send water flooding into Mojave Desert communities that are home to about 300,000 people, authorities said Friday.The U.S. Army Corps of Engineers announced that it has changed its risk characterization of the Mojave River Dam from low to high urgency of action. The Corps says it estimates that only 16,000 people in those communities would be affected by flooding.The earthen dam was built in the 1970s near the San Bernardino Mountains northeast of Los Angeles. It was designed for flood control and is usually dry.The 200-foot-high (61-meter-high) dam has never breached but an assessment last year found that during an extreme storm, water could flow over the top and erode the dam.That could threaten Apple Valley, Hesperia, Victorville, Barstow and even the tiny town of Baker, more than 140 miles (225.3 kilometers) downstream.The chances of such a storm are only about 1-in-10,000, said Luciano Vera, spokesman for the Los Angeles district of the Army Corps of Engineers.However, "all it takes is one event ... one Katrina, one Hurricane Harvey," Vera said. "These storms are happening more and more, so this is our way of looking toward the future."The corps has been working with local communities on emergency preparation plans and will also begin a study on upgrading and strengthening the dam, Vera said.Since 2005's devastating Katrina, the corps has been looking at all of its 700 dams nationwide.In May, the corps upgraded the risk characterization of Prado Dam to high urgency. That dam is located on the Santa Ana River in the Los Angeles suburb of Corona. Dozens of Southern California cities with about 1.4 million people live downstream.Work to improve the dam has been under way since 2002 to increase the amount of floodwaters and sediment it can store.In 2017, some 200,000 people in three Sierra Nevada counties were forced to evacuate after spillways at the Oroville Dam crumbled and fell away during heavy rains.Flooding didn't happen, however, and the dam has since been repaired. 2092
