New results on a possible COVID-19 vaccine from Oxford University and drugmaker AstraZeneca suggest it is safe and about 70% effective.Some experts say that shows it is likely to win approval, but questions remain about how well it may help protect those over 55. That's a key concern for a vaccine that health officials hope to rely on around the world because of its low cost, availability and ease of use.Partial results from tests of the vaccine in the United Kingdom, Brazil and South Africa were published Tuesday by the medical journal Lancet.“Today, we have published the interim analysis of the Phase III trial and show that this new vaccine has a good safety record and efficacy against the coronavirus,” said Professor Andrew Pollard, Director of the Oxford Vaccine Group and Chief Investigator of the Oxford Vaccine Trial. “We are hugely grateful to our trial volunteers for working with us over the past eight months to bring us to this milestone.”Researchers claim the vaccine protected against disease in 62% of those given two full doses and in 90% of those initially given the half dose. However, independent experts have said the second group was too small — 2,741 people — to judge the possible value of that approach and more testing is needed.The interim analysis for efficacy was based on 11,636 participants accruing 131 symptomatic infections from the Phase III trials.In addition to the Oxford led program, AstraZeneca is conducting a large study in the US and globally. In total, Oxford University and AstraZeneca expect to enroll more than 60,000 participants globally.The company says it’s also making progress in manufacturing with a capacity of up to 3 billion doses of the vaccine in 2021 on a rolling basis, pending regulatory approval. The vaccine can be stored, transported and handled at normal refrigerated conditions for at least six months and administered within existing health care settings. 1940

NEW YORK (AP) — People are more likely to return a lost wallet if it contains money — and the more cash, the better.That's the surprising conclusion from researchers who planted more than 17,000 "lost wallets" across 355 cities in 40 countries, and kept track of how often somebody contacted the supposed owners.The presence of money — the equivalent of about in local currency — boosted this response rate to about 51%, versus 40% for wallets with no cash. That trend showed up in virtually every nation, although the actual numbers varied.Researchers raised the stakes in the U.S., the United Kingdom and Poland. The response jumped to 72% for wallets containing the equivalent of about , versus 61% for those containing . If no money was enclosed, the rate was 46%.How can this be?"The evidence suggests that people tend to care about the welfare of others, and they have an aversion to seeing themselves as a thief," said Alain Cohn of the University of Michigan, one author who reported the results Thursday in the journal Science.Another author, Christian Zuend of the University of Zurich, said "it suddenly feels like stealing" when there's money in the wallet. "And it feels even more like stealing when the money in the wallet increases," he added. That idea was supported by the results of polls the researchers did in the U.S., the U.K. and Poland, he told reporters.The wallets in the study were actually transparent business card cases, chosen so that people could see money inside without opening them. A team of 13 research assistants posed as people who had just found the cases and turned them in at banks, theaters, museums or other cultural establishments, post offices, hotels and police stations or other public offices. The key question was whether the employee receiving each case would contact its supposed owner, whose name and email address were displayed on three identical business cards within.The business cards were crafted to make the supposed owner appear to be a local person, as was a grocery list that was also enclosed. Some cases also contained a key, and they were more likely to get a response than cases without a key. That led the researchers to conclude that concern for others was playing a role, since — unlike money — a key is valuable to its owner but not a stranger.The effect of enclosed money appeared in 38 of the 40 countries, with Mexico and Peru the exceptions. Nations varied widely in how often the wallet's "owner" was contacted. In Switzerland the rate was 74% for wallets without money and 79% with it, while in China the rates were 7% and 22%. The U.S. figures were 39% and 57%.The study measured how employees act when presented with a wallet at their workplaces. But would those same people act differently if they found a wallet on a sidewalk?"We don't know," said Michel Marechal, an author from the University of Zurich. But he said other analyses suggest the new results reflect people's overall degree of honesty.Shaul Shalvi of the University of Amsterdam, who wrote a commentary that accompanied the study, told The Associated Press that he suspected the study does shed light on how people would act with a wallet found on the street.He said the results "support the idea that people care about others as well as caring about being honest."Robert Feldman, psychology professor at the University of Massachusetts Amherst who didn't participate in the work, said he suspected the experiment might have turned out differently if involved "everyday people" rather than employees acting in an official capacity.But Feldman called the study impressive and said it seems like "a very real result."Dan Ariely, a psychology professor at Duke University who didn't participate in the research, said the conclusions fit with research that indicates keeping a larger amount of money would be harder for a person to rationalize."It very much fits with the way social scientists think about dishonesty," he said. 3987

NEW YORK (AP) — J.C. Penney says it is closing 154 stores nationwide in what it is calling the first phase of its efforts to shrink its footprint. According to USA Today, the retailer received bankruptcy court approval on Thursday to begin liquidation sales at stores that are permanently closing. The Plano, Texas-based retailer said it could take about 10 to 16 weeks to complete the closures. “While closing stores is always an extremely difficult decision, our store optimization strategy is vital to ensuring we emerge from both Chapter 11 and the COVID-19 pandemic as a stronger retailer with greater financial flexibility to allow us to continue serving our loyal customers for decades to come,” said Jill Soltau, chief executive officer of JCPenney in a press release. “I am incredibly grateful to our talented associates for their ongoing dedication and their passion for meeting and exceeding our customers’ expectations during this difficult and uncertain time. All impacted associates will be treated with the utmost consideration and respect.”Penney filed for bankruptcy protection last month, making it the biggest retailer to do since the coronavirus pandemic forced non-essential stores to be shut down temporarily. As part of its bankruptcy reorganization, Penney said it planned to permanently close nearly a third of its 846 stores in the next two years. That would leave it with just over 600 locations. 1431

NORFOLK, Va. (AP) — A company’s plan to retrieve the Titanic’s radio has sparked a debate over whether the famous shipwreck still holds human remains. Lawyers for the U.S. government have raised the question during their ongoing court battle to block the planned expedition. They cite archaeologists who say remains could still be there. The lawyers say RMS Titanic Inc. fails to consider that in its dive plan. But the company says human remains likely would’ve been noticed after roughly 200 dives to the site. The company also says remains would've dissolved in the harsh ocean environment. The luxury ocean liner sank in 1912 after striking an iceberg in the North Atlantic. 686
