It's a bit hard to describe Vietnam's Intergenerational Self Help Clubs.

But one thing is easy to say. If you're older — like above the age of 60 — and need help, the club will help you get it. That could mean a microloan if times are tough, a drum lesson as a chance for self-expression and social activity (and to prove that old people can play drums, too). And during the pandemic, the clubs have played a critical role informing and supporting its members.

There are around 3,000 of the clubs in Vietnam, with 160,000 participants, most of them older people.

More than 100,000 people are taking part in studies to see if one or more COVID-19 vaccine candidates actually work.

The United States is home to the world's best-known technology companies, but so far the use of smartphones to fight the coronavirus has been tepid at best.

Smartphones have the potential to be a powerful tool in tracking the spread of COVID-19. They can tell you exactly how close you've been to other people, for how long and keep a detailed log of everyone you've been around for the last 14 days. Linked to testing systems, they can rapidly alert you if someone you've been in contact with tests positive.

Critics of Facebook and Twitter — and even some people inside the companies — say dramatic action is needed to counter the way the platforms supercharge false, and sometimes dangerous, claims.

Facebook says it has taken down a network of China-based fake accounts whose posts included content about the U.S. presidential election.

Most of the activity by the more than 180 fake accounts, groups and pages was focused on Southeast Asia, Nathaniel Gleicher, Facebook's head of security policy, said in a blog post Tuesday.

When big, important people die, it's easy to overuse the term "iconic," but the title fits Justice Ruth Bader Ginsburg. Outside the halls of the Supreme Court, she had another life in pop culture as a symbol of both dissent and feminism. And maybe nothing has cemented her place there more than Saturday Night Live.
