NEW YORK (AP) — Walmart said in a press release that the ammunition and firearms removed from displays at U.S. stores on Thursday was returned to the sales floor on Friday.“After civil unrest earlier this week resulted in damage to several of our stores, consistent with actions we took over the summer, we asked stores to move firearms and ammunition from the sales floor to a secure location in the back of the store in an abundance of caution," the company stated in a news release. "As the current incidents have remained geographically isolated, we have made the decision to begin returning these products to the sales floor today.”Walmart said on Thursday that it had removed ammunition and firearms from displays at U.S. stores, citing "civil unrest" in some areas. The nation's largest retailer, based in Bentonville, Arkansas, sells firearms in about half of its 4,700 stores. The discounter said the items remained available for purchase by customers. Walmart made a similar move in the wake of the police killing of George Floyd that set off sometimes violent demonstrations against police brutality and injustice against Blacks. Last year, Walmart stopped selling handgun and short-barrel rifle ammunition while requesting that customers not openly carry firearms in its stores, even where state laws allow it. The company also ended the sale of handguns in Alaska, the only state where the discounter sold them. 1432

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 ORLEANS, La. – A critically endangered gorilla that was born at a New Orleans zoo just six days ago has died.The Audubon Zoo says its animal care staff noticed Wednesday evening that the infant western lowland gorilla seemed lethargic and weak in the arms of its mother, 13-year-old Tumani. The young gorilla was transferred to the zoo’s animal hospital, but the veterinarian team could not revive it.The zoo says Tumani is currently being monitored by the veterinary team and the entire troop was given the opportunity to grieve the loss of the infant.The zoo says it took extra precautions leading up to the birth, working with Tumani on maternal training to prepare her to be comfortable with the possibility of staff assisting her with feeding or caring for the infant.“There are many risks involved with gorilla births and unfortunately, it is not unusual for a first-time gorilla mom to lose an offspring,” said Dr. MacLean, Audubon’s Senior Veterinarian, in a press release. “Our veterinary team worked with outside medical experts on site including Species Survival Plan Gorilla Birth Management Team, OB-Gyns, and neonatologist to help us prepare and manage this birth.”The mother and baby initially appeared to be doing very well, according to the zoo. Animal care staff were closely monitoring the infant’s health to ensure that mother and baby received the care needed. The infant reportedly appeared to be feeding and progressing well.The zoo says the cause of death is underdetermined at this time. Initially, officials say it appears that there was a lack of adequate lactation from Tumani to support the infant, but they plan to perform a necropsy to determine cause of death. Results will be available in a few weeks.“We are heartbroken over the loss,” said Ron Forman, Audubon Nature Institute President and CEO. “This has been a work in progress for many years, from the introduction of the new troop members to the announcement of the birth, everyone involved has worked tirelessly. I am incredibly proud of our team. We will continue to contribute to the conservation of this amazing species.”Many gorilla populations have declined or disappeared over the past few decades. Western lowland gorillas have been assessed by the International Union for Conservation of Nature as critically endangered, with a population decline of more than 80%, mainly due to illegal hunting, disease, habitat loss, and an increase in poaching. 2457
