LOS ANGELES (AP) — California is not burning. At least not as much as it has in recent years.Acreage burned through Sunday is down 90% compared to the average over the past five years and down 95% from last year, according to statistics from the Department of Forestry and Fire Protection.The stats are good news for a state that has seen terrifyingly destructive and deadly blazes the past two years, but the worst of those fires occurred in the fall.The precipitous drop could be due to the amount of precipitation the state received during a winter of near-record snowfall and cooler-than-average temperatures — so far.Scott McLean, a spokesman for CalFire, said the state hasn't dried out as quickly this year and the temperatures haven't been as consistently hot. Hot spells have been followed by cooler weather and winds haven't been strong."It's a roller coaster with temperatures this year," McLean said. "There have been very little winds so far. We're crossing all fingers and appendages."The most current U.S. Drought Monitor map released last week shows only a tiny portion of California listed as abnormally dry. A year ago, almost the entire state was listed in a range from abnormally dry to extreme drought.Even after another very wet year in 2017 when Gov. Jerry Brown declared the end to a years-long drought, hot weather quickly sapped vegetation of moisture and nearly 4,000 fires had already burned more than 350 square miles (906 square kilometers) at this time of year. In October 2017, fast-moving, wind-driven blazes in Northern California killed 44 people and destroyed thousands of homes.Last year began with less rainfall and a smaller snowpack and the state dried out even faster with more dire the consequences. It was the worst fire year in state history in both acreage and deaths with the Camp Fire in November wiping out the town of Paradise, destroying nearly 15,000 homes and killing 86 people. At the same time, a Southern California wildfire burned across the Santa Monica Mountains and destroyed more than 1,500 structures.CalFire has fought fires on 38 square miles (98 square kilometers) this year, down from an average of 416 square miles (1,077 square kilometers) from 2014-18.Through the same date last year, a total of nearly 4,000 fires had burned more than 970 square miles (2,512 square kilometers). The number of fires this year, about 3,400, is only down about 15% from last year, meaning the fires are much smaller.Typically, 95% of the fires CalFire fights are smaller than 10 acres and "boy are we living up to that," McLean said.The state's figures don't compare data on fires on all federal lands, which account for about 45 percent of the state's acreage.Fires on U.S. Forest Service land this year, however, have also declined. To date, only 41 square miles have burned in national forests, compared to 350 square miles at this time last year, according to fire officials 2936

LOS ANGELES (AP) — When a wildfire burned across Big Sur two years ago and threatened hundreds of homes scattered on the scenic hills, thousands of firefighters responded with overwhelming force, attacking flames from the air and ground.In the first week, the blaze destroyed 57 homes and killed a bulldozer operator, then moved into remote wilderness in the Los Padres National Forest. Yet for nearly three more months the attack barely let up.The Soberanes Fire burned its way into the record books, costing 2 million as the most expensive wildland firefight in U.S. history in what a new report calls an "extreme example of excessive, unaccountable, budget-busting suppression spending."The report by Firefighters United for Safety, Ethics, and Ecology criticizes fire managers for not adapting their approach to the changing nature of the blaze. The nonprofit group, which gets funding from the Leonard DiCaprio Foundation and other environmental organizations, advocates ending "warfare on wildfires" by ecologically managing them.The report suggests the Forest Service response was the result of a "use it or lose it" attitude to spend its entire budget, which had been boosted by 0 million because of a destructive 2015 fire season. The agency managed to spend nearly all its 2016 money in a less-active fire season on about half the amount of land that burned the year before."They just kept going crazy on it," report author Timothy Ingalsbee said. "It wasn't demand-driven. It was supply-driven. They had all this extra money Congress had given them, and they had to justify that."Forest Service officials would not comment directly on the report. After asking The Associated Press to provide written questions, the agency declined to answer them and issued a short statement saying it was committed to reducing costs in similarly large fires."Protection of people first and then resources are our primary considerations," the statement said. "Every fire is evaluated to determine the appropriate strategy. We continually look for opportunities to improve outcomes and accountability and to find more cost-efficient and effective methods of managing wildfires."In addition to burning 206 square miles (534 square kilometers), the smoky fire closed signature parks in the area and put a damper on tourism in Big Sur during the peak season of its only industry. Monterey County estimated a 40 percent loss in revenue for the summer season in the area.An internal Forest Service review produced last year and obtained by the AP reached some of the same conclusions as Ingalsbee.For example, the department's review found that from Aug. 9 to Sept. 29, 2016, the number of threatened structures remained at 400 even as the fire grew by more than 90 square miles (230 square kilometers), which indicated the risk to property had abated as the flames burned into the wilderness. During that period, firefighting costs grew by 0 million.The review found forest managers didn't think they could deviate from the "overwhelming force concept" aimed at suppression. It also said the agency's protocol for managing long-term wildfires "does not sufficiently evaluate and adjust to changing risk."One challenge fire commanders faced was an outdated forest management plan for Los Padres that called for full suppression of all wildfires, Ingalsbee said.Mike Warren, a retired National Park Service firefighter who reviewed the report, questioned the wisdom of suppressing fires in remote wilderness where flames can help eliminate brush and other flammable vegetation that could fuel a later wildfire.When Warren was fire management officer at Sequoia and Kings Canyon National Parks, they would let blazes burn in the wilderness if they were confident the fire would stay in the park.The challenge in a place like the tourist-dependent Big Sur area is pressure from politicians, homeowners, businesses, loggers and ranchers to control the fire, Warren said."When is enough enough?" he said. "When do you back off say, 'This is it. We're just going to let it do its thing.' That takes some real political will."The Forest Service's internal review inspired Ingalsbee to file public records requests for other documents that led to his report.Among his findings:— About a fifth of the area burned was from fires set to clear brush and vegetation between outer perimeters and the active fire. One of these blazes jumped fire lines. These burnout operations created additional smoke and cost an estimated million.— A nearly million air campaign, including large air tankers that cost ,720 per hour, was largely ineffective. Retardant is effective at slowing flames only where ground crews can remove vegetation to create containment lines. But drops were done deep in steep, rugged wilderness where it was too dangerous to send crews, and even where flames never reached.— Bulldozers, which cost ,700 per hour, tore up wilderness, creating what Ingalsbee called "ghost roads" that will remain for years. The Forest Service spent an estimated million a day for weeks repairing damage done by dozers.The report concluded that once the blaze that broke out July 22, 2016, entered wilderness, there was little chance of stopping it before fall rains fell.Chad Hanson, an expert on fire and director of the John Muir Project, a nonprofit environmental group, said the cost was stunning, but the approach to fire was business as usual."It's sort of shocking that this massive amount of taxpayer money is being spent trying to suppress backcountry fires that are weather-driven and can't be stopped until the weather changes, rather than focusing resources on protecting communities," Hanson said. "On the other hand, I'm not surprised the Forest Service is doing this because it's been their practice for years."One beneficiary of the firefighting effort was Tom Little Bear Nason, who lives in a homestead in the national forest his family has owned for 150 years. He was also a contractor on the fire, with a team of dozer operators.Nason, chairman of the Esselen Tribe of Monterey County, credited the suppression effort with helping save his property. But he said costs shot up when managers went overboard on backfires and cut contingency lines too far from the fire.He also criticized the leadership on the fire, which changed every couple of weeks, for disregarding a pre-attack fire plan drawn up by local, state and federal agencies, tribal leaders, environmentalists and homeowners that included information on protecting historic and cultural sites.He said those plans "got chucked out the window" and led to significant losses. A homesteader cabin burned to the ground, sacred sites such as burial grounds were plowed over, and a rock where tribal members gave birth was struck by a bulldozer."Lots of efforts went to protect communities that went above and beyond" what was necessary, Nason said. "They were acting on the worst-case scenario." 6975

LOS ANGELES (CNS) - USC researchers have found the likely order in which COVID-19 symptoms first appear: fever, then cough and muscle pain, followed by nausea, and/or vomiting, and diarrhea, it was announced Thursday.Knowing the order of COVID-19's symptoms may help patients seek care promptly or decide sooner than later to self isolate, according to scientists at the USC Michelson Center for Convergent Bioscience. The information also may help doctors rule out other illnesses, or help doctors plan how to treat patients, and perhaps intervene earlier in the disease.The study, which appears in the journal Frontiers in Public Health, was led by doctoral candidate Joseph Larsen and scientists Peter Kuhn and James Hicks at the USC Michelson Center's Convergent Science Institute in Cancer."This order is especially important to know when we have overlapping cycles of illnesses like the flu that coincide with infections of COVID-19," said Kuhn, a USC professor of medicine, biomedical engineering, and aerospace and mechanical engineering. "Doctors can determine what steps to take to care for the patient, and they may prevent the patient's condition from worsening."Fever and cough are frequently associated with a variety of respiratory illnesses, including influenza, Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome. But the timing and symptoms in the upper and lower gastrointestinal tract set COVID-19 apart."Given that there are now better approaches to treatments for COVID- 19, identifying patients earlier could reduce hospitalization time," Larsen said.To determine COVID symptom chronology, the authors analyzed more than 55,000 confirmed coronavirus cases in China collected from Feb. 16 to Feb. 24 by the World Health Organization. They also studied a dataset of nearly 1,100 cases collected from Dec. 11 through Jan. 29 by the China Medical Treatment Expert Group via the National Health Commission of China.In addition, to compare the order of COVID-19 symptoms to influenza, the researchers examined data from 2,470 cases in North America, Europe and the Southern Hemisphere, which were reported to health authorities from 1994 to 1998."The order of the symptoms matter, " Larsen said. "Knowing that each illness progresses differently means that doctors can identify sooner whether someone likely has COVID-19, or another illness, which can help them make better treatment decisions." 2440

  

LONDON (AP) — Scientists at Oxford University say their experimental coronavirus vaccine has been shown in an early trial to prompt a protective immune response in hundreds of people who got the shot. British researchers first began testing the vaccine in April in about 1,000 people, half of whom got the experimental vaccine. Such early trials are usually designed only to evaluate safety, but experts were also looking to see what kind of immune response was provoked. In research published Monday, scientists said that they found their experimental COVID-19 vaccine produced a dual immune response in people who got the shot. 637

  

LOS ANGELES (CNS) - Denny's Inc. is being sued by a man who says he was eating at one of the dining chain's restaurants near downtown Los Angeles in 2018 when he was stabbed by a homeless man.Ralph Martinez maintains in his Los Angeles Superior Court lawsuit that Denny's management was aware of previous assaults at the location. He alleges negligence, premises liability, assault, battery and intentional infliction of emotional distress.A Denny's representative did not immediately reply to a request for comment on the complaint brought Friday. The plaintiff is seeking unspecified compensatory and punitive damages.According to his court papers, Martinez was having dinner alone at the Denny's in the 800 block of South Figueroa Street on June 24, 2018, when a homeless man entered the location and "immediately began making racial slurs at other customers and began harassing the other customers."The homeless man then approached Martinez and began hitting him before stabbing him several times with a knife, according to the lawsuit."At no point in time did defendant's staff intervene or even ask or escort the homeless man to leave," the suit says.Denny's did not have any security guards at the restaurant even though management knew of previous violent incidents there, the suit alleges. 1306
