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) — 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 (AP) — A Los Angeles woman has been sentenced to 15 years in prison in the beating of a 91-year-old man that was captured on video and shared widely on social media.Thirty-year-old Laquisha Jones was sentenced Thursday following her no contest plea to elder abuse in December.Prosecutors say Jones severely beat Rodolfo Rodriguez in the face with a brick on July 4 as the man was taking a walk. They say Rodriguez did nothing to provoke the attack.RELATED: 91-year-old man beaten with brick in California, told 'go back to Mexico'A witness recorded video of Rodriguez as he sat dazed, his face bloodied, after being beaten. The witness, Misbel Borjas, also took a photo of a woman with a brick in her hand.Borjas says Jones yelled at Rodriguez: "Go back to your country."Prosecutors added hate crime allegations in an amended complaint, but they were not part of the plea agreement that ended the case. 922

LOS ANGELES (AP) — Kevin Hart has a new job — he will host the 2019 Academy Awards, a role the prolific actor-comedian says fulfills a longtime dream.Hart announced his selection for the 91st Oscars in an Instagram statement Tuesday. The Academy of Motion Picture Arts and Sciences followed up with a tweet that welcomed him "to the family."The announcement came hours after trade publication The Hollywood Reporter posted a story calling the Oscars host position "the least wanted job in Hollywood."Hart clearly doesn't feel that way, writing on Instagram that it has been on his list of dream jobs for years. The 2019 Oscars will be broadcast Feb. 24 on ABC."I am blown away simply because this has been a goal on my list for a long time...To be able to join the legendary list of host that have graced this stage is unbelievable," Hart wrote. "I know my mom is smiling from ear to ear right now."I will be sure to make sure this years Oscars are a special one," Hart wrote.Hart takes over hosting duties from Jimmy Kimmel, who presided over the last two ceremonies, including 2016's flub that resulted in the wrong best picture winner being announced. Last year's ceremony was an all-time ratings low, and the film academy has announced a series of changes to the upcoming show .Those include shortening the broadcast to three hours, and also presenting certain categories during commercial breaks and broadcasting excerpts of those winners' speeches later in the show.The 39-year-old Hart has become a bankable star with films such as "Ride Along," ''Jumanji: Welcome to the Jungle" and "Night School."Celebrities including Martin Lawrence and Chris Rock, who hosted the ceremony in 2005 and 2016, posted congratulatory messages about Hart's selection Tuesday night."Damn I've lost another job to Kevin Hart," Rock posted on Instagram, echoing a joke he told during his 2016 opening monologue . "They got the best person for the job." 1946

LONDON (AP) — An American tourist from Louisiana helped stop a hammer-wielding thief who unsuccessfully tried to steal the Magna Carta at Salisbury Cathedral, working in tandem with a church employee to prevent the man from escaping.Matthew Delcambre, of New Iberia, Louisiana, told The Associated Press that he and his wife Alexis were sightseeing in the southwestern English city when a man tried to shatter the glass encasing the precious manuscript in the church's Chapter House. After Alexis tried to raise the alarm to others, Delcambre and other bystanders banded together to try to hold the thief back behind the doors of the Chapter House.When the thief pushed past them, the 56-year-old IT expert gave chase into an outer courtyard. He grabbed the man's arm near the courtyard gate and knocked away the hammer. A church employee tackled him and held him down."It wasn't me by myself," he said. "It was completely a group effort."The Magna Carta, which was protected by two layers of thick glass, wasn't damaged.Wiltshire police said Saturday that a 45-year-old man was freed on bail until Nov. 20 as officers continue their investigation.Salisbury Cathedral's Magna Carta is one of four existing specimens of the 1215 charter that established the principle that the king is subject to the law. It is considered the founding document of English law and civil liberties and influenced the creation of the U.S. Constitution.The document, Latin for "Great Charter" was short-lived. Despotic King John, who met disgruntled barons and agreed to a list of basic rights, almost immediately went back on his word and asked the pope to annul it, plunging England into civil war. It was re-issued after the king's death.Even so, its importance cannot be underestimated, as it has inspired everyone from Mahatma Gandhi to Nelson Mandela. Matthew Delcambre, the director for the Center for Business & Information Technologies at the University of Louisiana at Lafayette, said he has been a bit taken aback by the attention his efforts have earned, but told his story so that his efforts would not be exaggerated at the expense of others.Of all those who played a part in corralling the thief, he credits his wife Alexis first and foremost, since it was she who noticed the thief coming out of the disabled bathroom wielding the hammer and tried to get help. He played down earlier reports which depicted him as the hero, and said the people who should get the credit are cathedral workers and volunteers who tried to protect the Magna Carta."The heroes are the staff employees of the cathedral who protected the document, helped catch the guy and helped retain him until the police got there," he said. "It was a team effort." 2735
