NEW YORK CITY — Two U.S. marshals and a New York City police officer were injured in a shootout in the Bronx early Friday that left one suspect dead and another injured, law enforcement sources say.The New York City Fire Department (FDNY) said a report came in at around 5:30 a.m. ET about a shooting on Ely Avenue, near Edenwald Avenue in the Wakefield neighborhood of the Bronx.Aerial footage shows a large police presence in the area, including three ambulances.One marshal was shot in the arm and thigh and the second was shot in the leg, according to police. The NYPD detective injured his leg during the incident.The three law enforcement officials were transported to local hospitals for treatment, along with a suspect who sustained injuries to his head. It's not known if the suspect was suffering from gunshot wounds.Previous reporting indicated that the three law enforcement officers injured were all U.S. marshals.According to WHDH-TV in Boston, the suspect who was killed in the shootout is Andre K. Sterling, 35. He was wanted in connection with the shooting of a Massachusetts state trooper on Nov. 20. The state trooper survived that shooting, but Sterling escaped the scene. 1200

New research suggests that antibodies the immune system makes to fight the new coronavirus may only last a few months in people with mild illness, but that doesn’t mean protection also is gone or that it won’t be possible to develop an effective vaccine.“Infection with this coronavirus does not necessarily generate lifetime immunity,” but antibodies are only part of the story, said Dr. Buddy Creech, an infectious disease specialist at Vanderbilt University. He had no role in the work, published Tuesday in the New England Journal of Medicine.The immune system remembers how to make fresh antibodies if needed and other parts of it also can mount an attack, he said.Antibodies are proteins that white blood cells called B cells make to bind to the virus and help eliminate it. The earliest ones are fairly crude but as infection goes on, the immune system becomes trained to focus its attack and to make more precise antibodies.Dr. Otto Yang and others at the University of California, Los Angeles, measured these more precise antibodies in 30 patients diagnosed with COVID-19 and four housemates presumed to have the disease. Their average age was 43 and most had mild symptoms.Researchers found that the antibodies had a half-life of 73 days, which means that half of them would be gone after that much time. It dovetails with a previous report from China also suggesting antibodies quickly fade.The results “call for caution regarding antibody-based ‘immunity passports,’ herd immunity, and perhaps vaccine durability,” the California authors write.That’s true, Creech said, but other parts of the immune system also help confer protection. Besides churning out antibodies, B cells develop a memory so they know how to do that again if needed.“They would get called into action very quickly when there’s a new exposure to the virus. It’s as if they lie dormant, just waiting,” he said.Other white blood cells called T cells also are better able to attack the virus the next time they see it, Creech said.Although circulating antibodies may not last long, what we need to know is if and how people remake antibodies if exposed to the coronavirus again and if they protect against another infection, Alison Criss, an immunologist at the University of Virginia, wrote in an email. “We also need to know if there is a protective T cell response” that reappears.Vaccines, which provoke the immune system to make antibodies, might give longer-lasting protection than natural infection because they use purified versions of what stimulates that response, she noted.Creech agreed.“This shouldn’t dissuade us from pursuing a vaccine,” he said. “Antibodies are only a part of the story.”___Marilynn Marchione can be followed on Twitter at http://twitter.com/MMarchioneAP___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

NEW YORK (AP) — In the most seismic shift by a Hollywood studio yet during the pandemic, Warner Bros. Pictures on Thursday announced that all of its 2021 film slate — including a new “Matrix” movie, “Godzilla vs. Kong” and the Lin-Manuel Miranda adaptation “In the Heights” — will stream on HBO Max at the same time they play in theaters. “No one wants films back on the big screen more than we do," said Ann Sarnoff, chief executive of WarnerMedia Studios in a press release. "We know new content is the lifeblood of theatrical exhibition, but we have to balance this with the reality that most theaters in the U.S. will likely operate at reduced capacity throughout 2021."Films will debut simultaneously in theaters and on HBO Max in the U.S. After one month, they will stop streaming and continue to play only in theaters.The movies slated to be released are: "The Little Things," "Judas and the Black Messiah," "Tom & Jerry," "Godzilla vs. Kong," "Mortal Kombat," "Those Who Wish Me Dead," "The Conjuring: The Devil Made Me Do It," "In The Heights," "Space Jam: A New Legacy," "The Suicide Squad," "Reminiscence," "Malignant," "Dune," "The Many Saints of Newark," "King Richard," "Cry Macho," and "Matrix 4." Warner Bros. said all the films will be released in 4K Ultra HD and HDR. The news comes after Warner Bros. announced last month the decision to release “Wonder Woman 1984” to theaters and on HBO Max on Dec. 25. 1435

She's also a member of the Council on Foreign Relations.She earned her M.B.A. from Harvard Business School and an M.A. in economics from Cambridge University.Fraser's climb to the CEO role is a major accomplishment in an industry long dominated by men.
