LOS ANGELES (CNS) - Newly published research indicates there's an almost one-in-four chance the mountain lions living in the Santa Monica and Santa Ana mountains could become extinct in those areas within 50 years as a result of urban encroachment, inbreeding, vehicle strikes, rat poison and wildfire, it was reported today.In the face of such a dire prognosis, what biologists call an extinction vortex, conservationists are considering a desperate and controversial remedy: capturing pumas in one part of the Santa Anas and trucking them across the 15 Freeway so that they can breed with isolated mates on the other side of traffic."Wildlife managers never want to be a shuttle service for wild animals,'' said Justin Dellinger, senior environmental scientist with the Wildlife Investigations Laboratory at the California Department of Fish and Wildlife, the Los Angeles Times reported. But translocation has potential merit in the short term; after all it helped bring the critically endangered Florida panther back from the brink.Mountain lions are not endangered in California, but groups living in the Santa Monica and Santa Ana ranges now find themselves in genetic peril. Separated by freeways and lethal traffic, they are unable to range freely and are growing increasingly inbred, researchers say.In the Santa Monica Mountains, the 101 Freeway exists as a near impenetrable barrier to gene flow for a group of 10 mountain lions; in the Santa Ana Mountains, the 15 Freeway limits the movement of a family of 20 cougars.Sometimes, the animals manage to cross freeways without getting hit. At least seven cougars have crossed the 15 Freeway near Temecula in the last 15 years, and one sired 11 kittens. The fact that only one managed to reproduce, however, shows how difficult it is to diversify the gene pool in the lions still prowling the range.A population viability study published in the journal Ecological Applications predicts extinction probabilities of 16 to 28 percent over the next 50 years for these lions, which have the lowest genetic diversity documented for the specie aside from the critically endangered Florida panther.Study authors note also that wildfire and disease could result in "catastrophic mortality'' and further hasten the animals' disappearance.However, extinction probabilities were significantly reduced when computer models simulated the influence of two immigrant lions per year in areas blocked by development and freeways, according to a team of researchers that included Winston Vickers, an associate veterinarian at the UC Davis Karen C. Drayer Wildlife Health Center, and Seth Riley, an ecologist with the Santa Monica Mountains National Recreation Area, The Times reported. 2731

LONDON (AP) — A half-million people in the English city of Liverpool will be regularly tested for COVID-19 in Britain's first citywide trial of widespread, rapid testing that the government hopes will be a new weapon in combatting the pandemic.In a statement Tuesday, the government said that testing would begin later this week at sites throughout the city using various technologies, including new methods that can provide results in an hour or less.Everyone who lives or works in the city in northwestern England will be offered the test, regardless of whether they have symptoms.Through a partnership between Liverpool City Council, NHS Test, and Trace and Ministry of Defence, the government would provide the tests.The government said approximately 2,000 military personnel on Thursday would help plan the logistics and deliver tests."Anyone who tests positive, using either a lateral flow test or an existing swab test, must self-isolate along with their household immediately, and their contacts will be traced," officials stated in the press release.The government said anyone who tests – and contacts required to self-isolate – will be entitled to the ￡500 Test and Trace Support Payment.On Monday, 18,950 new confirmed cases of coronavirus were recorded in the UK, the BBC reported. 1301

LOS ANGELES (CNS) - A pair of active-duty U.S. Marines stationed at Camp Pendleton were arrested Tuesday morning on a federal grand jury indictment charging one of the Marines and three civilians with conspiring to distribute narcotics -- including oxycodone pills laced with fentanyl -- to civilians and members of the Marine Corps, one of whom suffered a fatal drug overdose in May.Lance Cpls. Anthony Ruben Whisenant, 20, and Ryan Douglas White, 22, were expected to make their initial appearances Tuesday afternoon in U.S. District Court in Los Angeles. Whisenant allegedly distributed narcotics to fellow Marines, including the one who overdosed, and White is charged with being an accessory after the fact for allegedly attempting to hinder the apprehension of Whisenant and an alleged drug supplier named in the indictment.The 14-count superseding indictment also charges:-- Jordan Nicholas McCormick, 26, of Palmdale, the lead defendant and the conspiracy's alleged supplier of LSD, ecstasy, cocaine and oxycodone pills laced with fentanyl to co-conspirators-- Gustavo Jaciel Solis, 24, of Sylmar, who allegedly distributed McCormick's drugs to civilians and military personnel-- Jessica Sarah Perez, 23, of Pacoima, who allegedly distributed narcotics, including fentanyl and cocaine, to civilian customersOn Aug. 11, Solis and Perez were indicted on fentanyl and cocaine distribution charges, and Solis was indicted on firearms-related charges. They have pleaded not guilty and their trial date is scheduled for Oct. 27. Solis is in federal custody and Perez is free on ,000 bond.Tuesday's updated indictment adds McCormick -- who is also in federal custody -- Whisenant and White as defendants, in addition to adding charges to the original indictment. According to the indictment, the conspiracy lasted from last November through this month and involved multiple sales of fentanyl- laced oxycodone to an undercover buyer, often for amounts exceeding ,000 per buy.On May 22, Solis sold 10 pills of oxycodone laced with fentanyl to an active-duty Marine who died of a drug overdose in the early morning hours of May 23, the indictment alleges.In addition to the conspiracy charge, McCormick, Solis, Whisenant and Perez face substantive charges of distribution of narcotics, including fentanyl. McCormick and Solis are also charged with possessing firearms in furtherance of drug crimes.If convicted, McCormick and Solis would face a sentence of 10 years to life in federal prison, and Whisenant and Perez would each face up to 20 years behind bars. White, if convicted, would face up to 10 years in federal prison. 2637

Logging onto social media platforms can provide joy for many people. Grandparents can see pictures of their grandkids. People can connect with peers or catch up on topics they follow. But in the same social media feeds are posts that seem normal but pose a danger that isn’t always obvious.Misinformation isn’t always a clearly false statement of fact. It can be one subtle change that twists the truth. Experts say misinformation is spreading faster and easier than ever before. They’re hoping to address the issue by asking why people believe and share false information.Researchers say the process people use to process and share information, particularly on social media, can help provide some answers. Studies show people tend to use cognitive shortcuts when they decide what to share online.For a person sharing a particular article or picture, those shortcuts involve asking themselves:Is the content consistent with what they have shared before?Is the content consistent with what most others share?Does the content come from a credible source?Researchers think manipulating those factors could be key in getting people to share posts with misinformation and increase its organic reach.Experts think age is another factor in how misinformation spreads online.One study found people 65 and older shared seven times more misinformation on social media during the 2016 election cycle than the youngest age group studied. Researchers say a lack of digital media literacy in seniors could help explain the gap. They’re now pushing initiatives to increase literacy rates.There’s one way researchers found to help stop people from sharing misinformation and that’s a simple reminder to consider the source and accuracy of information before sharing. 1758

LOS ANGELES (CNS) - Warning again that holiday gatherings can lead to spikes in coronavirus cases, Los Angeles County's public health director said Wednesday residents should begin planning safer ways to celebrate upcoming fall holidays, but the county backed down from its previously announced ban on trick-or-treating for Halloween."Our guidelines have been slightly revised, so we'd ask that people go back and look at them to distinguish between those activities that are not permitted by the health officer order -- that includes events, gatherings parties -- those are just not allowed," Barbara Ferrer said. "They're not allowed for anything. ... The only activities you can have a party or gathering for are with those people that are in your household."On Tuesday, the Department of Public Health posted Halloween guidelines on its website stating that door-to-door trick-or-treating is banned under the county health order, as is "trunk-to-trunk" treat distribution, in which children take candy from trunks of parked cars. By Wednesday, however, the guidelines were changed, with trick-or-treating listed as "not recommended," instead of "not permitted."Despite that change, Ferrer still insisted that allowing children to go door-to-door during the coronavirus pandemic isn't safe."Trick-or-treating, we're highly recommending that it not happen," she said. "We don't think it's an appropriate activity during a pandemic. ... You know, there's no guarantee when you go trick-or-treating that your child goes up to a house where the person who opens the door is wearing a face covering. And when you don't know the people opening the door, there's no guarantee they're not sick and that the candy they're passing out that they've touched may not be safe for you to want your child to be sharing."Ferrer again walked through data from the past several months showing surges in coronavirus cases, hospitalizations and deaths following the spate of public gatherings that occurred over the Fourth of July holiday. She said that as residents prepare for fall holidays -- such as Halloween and Thanksgiving -- the statistics should serve as a warning."Increases in cases and hospitalizations that may happen in the future will always be followed by increases in deaths," she said.It remained too early to tell if the Labor Day holiday will lead to a spike in cases similar to that seen after the Fourth of July. Due to the 14-day incubation period of COVID-19, it generally takes two weeks to determine if such as surge has occurred."I do want to reinforce the need for us to remain cautious as we go about all of our business during the day and evening, remembering that we can be positive and infect others at any point in time, and others can infect us and the people that we love at any point in time," Ferrer said.She said the county was "extraordinarily successful" in reducing case rates during August because of residents' behaviors and adherence to health orders."But I want to note that every time we have seen transmission rates fall, our natural response is to let up and want to return to greater normalcy," Ferrer said. "This will be especially true as we're going into the fall and winter months, when we have a number of important religious and secular holidays. But unfortunately what we have learned over the last seven months is that we cannot return to normal at this time. We actually need to maintain even more our vigilance so we can continue to suppress the spread of the virus and get to a place where we can safely reopen additional sectors, particularly our schools."Ferrer announced another 61 coronavirus-related deaths in the county, bringing the cumulative countywide total from throughout the pandemic to 6,090. She also announced another 671 new cases, lifting the overall total to 249,859.She noted that the case number continues to be unusually low due to lags in reporting from the holiday weekend, along with the limited availability of testing due to the holiday and the excessive heat.A total of 936 people were hospitalized due to the virus as of Wednesday, continuing a roughly monthlong decline. 4151
