NEW YORK, N.Y. – Peloton has issued a recall for some of its bike pedals due to a laceration hazard.Thursday, that home fitness company said about 54,000 of its PR70P clip-in pedals are being recalled. They’re the first-generation pedals fitted on Peloton bikes sold between July 2013 and May 2016.The company has received at least 120 reports of pedals breaking, including 16 reports of leg injuries, five of which required medical care, according to the U.S. Consumer Product Safety Commission.The Peloton logo and the word "PELOTON" are molded into the pedal body. An orange Peloton symbol and white lettering spelling "PELOTON" are also printed on the top of the cleat binding. They were fitted on bikes that sold for about ,000.Peloton says anyone with these pedals should stop using them immediately and that it’s notifying all affected consumers directly on how to receive free replacement pedals, along with instructions for self-installation.Peloton says its pedals are warranted for one year and all remaining PR70P clip-in pedals in service are out of warranty. The company recommends consumers replace their pedals annually. 1146

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) — Curt Schilling, Roger Clemens, and Barry Bonds are the leading candidates returning to baseball's Hall of Fame ballot in a year without any favorites among the new names. Schilling was third behind Derek Jeter and Larry Walker with 278 of 397 votes last year, finishing at 70% and 20 votes shy in balloting by the Baseball Writers' Association of America. Clemens had 242 votes for 61% and Bonds 241 for 60.7%. Pitchers Barry Zito, Tim Hudson, Mark Buehrle, and A.J. Burnett, and outfielder Torii Hunter are among the top newcomers on the ballot.To get into the Hall of Fame, you must receive 75% of the votes.According to the Associated Press, Bonds and Clemens were favorites to get into the Cooperstown, but since they have been suspected of steroid use, the likelihood of getting in is diminishing. Clemens denies using performance-enhancing drugs, and Bonds said he never knowingly took PEDs.All three will be making their ninth appearance on the BBWAA ballot this year, one short of the limit, the AP reported.Per the AP, voting will be announced on Jan. 26 and inductions will be made on July 25. Members of the BBWAA must have their ballots postmarked by Dec. 31. 1195

NEW YORK — New York Gov. Andrew Cuomo announced new guidance for bars and restaurants statewide Thursday.The governor says bars and restaurants in the state are now only allowed to serve alcohol to those who order food. He also announced that all service at bar tops must only be for those seated six feet apart or separated by physical barriers.Cuomo cited a lack of compliance on social distancing and the wearing of face coverings in bars and restaurants across the state."As we continue our science-based phased reopening, the number of hospitalizations and our rate of positive tests remain steady and low," Cuomo said. "But we need to remember our success fighting this virus is a function of our own actions. Mask wearing, social distancing and hand washing — basic as they may seem — are critical to controlling the spread of this virus. Especially now that we are seeing spikes in cases throughout the country, this is not the time to let up — especially on compliance enforcement. We know the prescription, and we know it works — we just need to be smart and do it."Cuomo's order was met with hesitancy by some local politicians. Erie County Legislature Minority Joe Lorigo said he planned to challenge the order in court."The Governor's announcement that bars and restaurants are no longer able to serve customers unless they order food with drinks is another egregious overreach of power. It is also yet another blow to bars, restaurants, and their employees that have taken multiple financial hits due to COVID-19," Lorigo said. "We cannot allow the Governor to continue haphazardly creating rules and regulations that only serve to hurt small businesses."This story was originally published by Anthony Reyes on WKBW in Buffalo. 1750
