A new study suggests misguided antibodies created as a response when someone is infected with the coronavirus could be the cause behind both more severe COVID-19 symptoms and those who report having symptoms for months after initially recovering.Researchers at Yale University found that COVID-19 patients they studied had high levels of antibodies that had turned on them; these wayward antibodies blocked antiviral defenses, wiped out helpful immune cells and attacked the body in several areas including the brain, blood vessels, liver and gastrointestinal tract.“Covid-19 patients make autoantibodies that actually interfere with immune responses against the virus,” Aaron Ring, an immunobiologist at Yale and senior author on the study, told The Guardian.Autoantibodies are antibodies that attack the body’s own proteins by mistake and disrupt their normal functions.“We certainly believe that these autoantibodies are harmful to patients with Covid-19,” said Ring. He added that the harmful effects of these autoantibodies could continue well after the initial infection has been overcome. He said antibodies can last for a long time, and if they are misguided in their attacks, the effects of their attacks on the body could also last a while.The study, which has yet to be peer reviewed and formally published, looked at antibodies from 194 COVID-19 patients and hospital workers with a range of symptoms and severity of symptoms.Other conditions, like lupus, multiple sclerosis and rheumatoid arthritis, are also made worse by the immune system malfunctioning and attacking the body. 1600

A species of turtle that was believed to have been extinct 20 years ago is making a comeback.The Wildlife Conservation Society (WCS) said in a press release this month that the Burmese roofed turtles now appear to be in little danger of biological extinction.Conservationists with WCS and Turtle Survival Alliance (TSA) rediscovered the creatures, which have natural smirks on their faces, in the wild in the early 2000s.Now, conservationists monitor sandbanks in Myanmar that female turtles use as nesting sites. Eggs are collected, incubated under natural conditions and then the offspring are “head-started” for eventual repatriation into the Chindwin River, WCS says.Conservationists say the captive population of these turtles is approaching 100,000.WCS says complementary conservation efforts are focused on the remaining wild population, which consists of five to six adult females and perhaps as few as two males.Steven G. Platt with WCS told The New York Times that if conservationists didn’t intervene, the turtle species would be gone for good.But while the species is headed in a good direction, Platt cautioned that unsustainable fishing practices remain a problem for the turtles’ recovery in nature. 1222
