Joe Biden's 2020 campaign unveiled a $750 billion higher education plan Tuesday that includes tuition-free community and technical college — with the federal government picking up 75% of the cost and allowing states to cover the rest — as well as more generous federal college loan programs, per the AP.

The state of play: Biden's plan isn't as far reaching as those put forth by his opponents, Bernie Sanders and Elizabeth Warren, who both offer plans exceeding $1 trillion. Sanders' plan proposes eliminating all student loan debt, while Warren calls for broad debt relief based on income.

Indoor air is the next coronavirus frontline

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.
