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

LONG BEACH (CNS) - Three former Long Beach Police Department officers wrote violent threats against Black Lives Matter activist Shaun King on a private Facebook page for California law enforcement officers, police confirmed Thursday.King, in an article he penned on Medium, said a private Facebook group for California law enforcement officers had members using their real names and "openly plotting and planning (his) assassination."Screenshots included in the Medium article show current and former officers of various California agencies saying "Toss this guy from a helicopter," "Need a sniper," "Shaun King needs to be put down," "I recommend retro active birth control, or post birth abortion, whatever you wanna call it," and other threats apparently aimed at King.According to King, the threats began with retired Long Beach Police Officer Laura Tartgaglione, who allegedly wrote, "The man who put this tweet out today is a FOUNDING MEMBER OF BLM, he also introduced Bernie Sanders at his attempted presidential run. I think (California) needs to start putting a team together of retired military, police and NRA MEMBERS! We have no protection. These criminals that the Democrats created need to be stopped."Information regarding the threats were sent to the Long Beach Police Department's Investigations Bureau for an internal review and recommendations regarding a criminal investigation, the department said. The FBI will assist the department with the investigation."The Long Beach Police Department is appalled and deeply disturbed by the tone and content of the posts which in no way reflect the core values and professional standards held by the men and women in our organization," the department said in a statement."We are 100% committed to working in partnership with our community to ensure that all people are treated with respect and professionalism and will not tolerate any bias, racism or threats to individuals."King raised doubt in the Medium article that police departments would be able to properly investigate their current and former officers for the threats."Who do you call to report the misconduct of current and retired law enforcement officers? Because I lack confidence in any law enforcement system to handle this, I feel the burden to release this publicly for my own safety and for the safety of my family," said King, who says he receives death threats every day. 2411

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

LOS ANGELES (AP) — The touching black-and-white drama "Roma" that follows a domestic worker for a middle-class family in 1970s Mexico City won the Oscar for best foreign language film Sunday.Director Alfonso Cuaron's deeply personal film with dialogue in Spanish and Mixtec gave Mexico its long-sought statuette in the foreign film category.The Netflix-produced film was inspired by Cuaron's own youth. "Roma" won him the best director award and one for best cinematography.The story develops in the midst of the turmoil that rocked Mexico in the early 70s, including the student demonstrations that in 1971 led to a massacre by a group backed by authorities. Society is fraying and the women of the house seem to take the brunt as they try to keep the family of four children afloat.The film beat four other contenders that also told the stories of individuals and families facing tumultuous social and historical times.The other nominated films were Polish filmmaker Pawel Pawlikowski's 20th-century romance "Cold War;" German director Florian Henckel von Donnersmarck's artist biopic "Never Look Away;" Japanese filmmaker Hirokazu Kore-eda's's subtle family story "Shoplifters;" and "Capernaum," a powerful neo-realist drama about a Syrian child refugee from Lebanon's Nadine Labaki.The foreign film statue is not given to a specific individual, but to the nominating country. Eighty-seven countries submitted movies for consideration this year.Mexico has competed for the trophy eight other times, most recently in 2011 with "Biutiful" by Alejandro Gonzalez Inarritu, but had never won. 1598
