Last week, the Trump administration announced a new policy that could force international students out of the United States if their universities move to online-only classes. This puts more than a quarter of a million Chinese students in the U.S. at risk of losing their visas. Students from Hong Kong are at special risk of being arrested upon their return due to a new Chinese security law. Plus, a majority of American parents see risks of having kids return to classrooms this fall. And, three different countries - the U.S., China and the United Arab Emirates - have planned launches to Mars this month.
