Remembering 9/11, Everyday Heroes, and the World's Largest Deserts

Curating the internet, weekly.

Good morning! It's Sunday, Sept. 13, and welcome to our Sunday Edition. Friday marked the 25th anniversary of the tragic attacks on US soil. To commemorate the event, we revisited what happened, how it changed America, and the impact it continues to have on its victims. Next, we featured a special Humankindness section honoring the courage and service shown by everyday people on 9/11. 

 

Below that, explore record heat in August (News in Context), the science behind cracking your knuckles (Etc.), and much more.

 

📖 Our Sunday edition digs deep into the context and rabbit holes behind the news. We'll be back with our regular Daily Digest tomorrow through Saturday.
