Logging onto social media platforms can provide joy for many people. Grandparents can see pictures of their grandkids. People can connect with peers or catch up on topics they follow. But in the same social media feeds are posts that seem normal but pose a danger that isn’t always obvious.Misinformation isn’t always a clearly false statement of fact. It can be one subtle change that twists the truth. Experts say misinformation is spreading faster and easier than ever before. They’re hoping to address the issue by asking why people believe and share false information.Researchers say the process people use to process and share information, particularly on social media, can help provide some answers. Studies show people tend to use cognitive shortcuts when they decide what to share online.For a person sharing a particular article or picture, those shortcuts involve asking themselves:Is the content consistent with what they have shared before?Is the content consistent with what most others share?Does the content come from a credible source?Researchers think manipulating those factors could be key in getting people to share posts with misinformation and increase its organic reach.Experts think age is another factor in how misinformation spreads online.One study found people 65 and older shared seven times more misinformation on social media during the 2016 election cycle than the youngest age group studied. Researchers say a lack of digital media literacy in seniors could help explain the gap. They’re now pushing initiatives to increase literacy rates.There’s one way researchers found to help stop people from sharing misinformation and that’s a simple reminder to consider the source and accuracy of information before sharing. 1758

LONDON (AP) — British Prime Minister Boris Johnson says Christmas gatherings can’t go ahead and non-essential shops must close in London and much of southern England as he imposed a new, higher level of coronavirus restrictions to curb sharply spreading infections. Johnson said the capital and other areas in southern England will move to an even stricter Tier 4 alert category that requires non-essential shops, hairdressers and indoor leisure venues to close after the end of business hours Saturday. Johnson also said that a planned five-day easing of socializing rules that would allow up to three households to meet in “Christmas bubbles” will be canceled for Tier 4 areas. In the rest of England, people will be allowed to meet in Christmas bubbles for just one day instead of five, as the government originally planned.“It is with a very heavy heart that I must tell you we cannot proceed with Christmas as planned,” Johnson said.A fast-moving new variant of the coronavirus that is more than 70% more transmissible than existing strains appears to be driving the rapid spread in London and southern England, Johnson said. London now has the highest infection rates in England.“There’s no evidence to suggest it is more lethal or causes more severe illness,” he stressed, or that vaccines will be less effective against it.England’s chief medical officer, Chris Whitty, said the U.K. has alerted the World Health Organization that the new variant identified this week appears to be accelerating the spread of COVID-19. The government’s scientific advisers came to that conclusion based on preliminary modelling figures, and they are continuing to analyze the available data, he said. 1699

LONDON (AP) — Scientists at Oxford University say their experimental coronavirus vaccine has been shown in an early trial to prompt a protective immune response in hundreds of people who got the shot. British researchers first began testing the vaccine in April in about 1,000 people, half of whom got the experimental vaccine. Such early trials are usually designed only to evaluate safety, but experts were also looking to see what kind of immune response was provoked. In research published Monday, scientists said that they found their experimental COVID-19 vaccine produced a dual immune response in people who got the shot. 637

LOS ANGELES (AP) — Some U.S.-based users of WeChat are suing President Donald Trump in a bid to block an executive order that they say would effectively prohibit U.S. access to the popular Chinese messaging app. The complaint was filed Friday in San Francisco and asks a federal court judge to stop Trump’s order from being enforced. It claims a ban would violate U.S. users’ constitutional rights. Trump has ordered sweeping but vague bans on transactions with the Chinese owners of WeChat and the TikTok app. He says they threaten U.S. national security. The Commerce Department is expected next month to reveal the types of transactions that would be banned. 669
