Welcome to Sunday! The top five stories on our website this week are displayed below.

Editor’s pick: How was your week? Mine was a little tough. After nearly two years of vigilance and three doses of vaccine, I took a rapid test last Sunday and saw one of those dreaded pink lines that meant I was positive for the coronavirus. I was lucky to have a mild case of the disease – but I still had a bunch of questions about how omicron was different from earlier variants that more often caused serious illness and why it suddenly seemed to be everywhere. If you have questions too, try reading this omicron explainer we published the other day. A group of three virologists and immunologists at the University of Colorado Boulder answers several good questions, including “Will omicron move the U.S. population closer to herd immunity?”.

And, if you’re feeling a little beat up by 2022 so far, check out this collection of stories on the theme of hope curated by Religion Editor Molly Jackson.
