Facebook will be sunsetting "M," its text-based and human-assisted virtual assistant it debuted in 2015, according to The Verge. The contract workers who took care of users' requests will be offered other jobs at the company, and automated aspects of the service will live on with the Messenger app.

The big picture: In the last couple of years, Facebook has really pushed to take its Messenger app to the next level with chat bots and experiments like M, but adoption has been slow.

A growing body of research has made it clear that airborne transmission of the coronavirus is possible.

Why it matters: That fact means indoor spaces can become hot spots. Those spaces also happen to be where most business and schooling takes place, so any hope for a return to normality will require better ways of filtering indoor air.

Online learning can be frustrating for students, teachers and parents, but some methods are working.

The big picture: Just as companies are using this era of telework to try new things, some principals, teachers and education startups are treating remote learning as a period of experimentation, too.
