Biden's 'America First' Policy on Afghanistan
As Kabul fell and the Taliban reclaimed power in Afghanistan over the past two days, the 45th and 46th presidents of the United States bickered over who was to blame. President Joe Biden, in a statement , put the onus on a deal made by former President Donald Trump; Trump fired back "Never would have happened if I were President!" even as Biden followed the path Trump had laid out.

Go Ahead. Vaccinate the Kids.
It's easy to argue for vaccinating adults and teenagers against COVID-19. Some think it's harder to make the case for kids under 12 years of age, and for understandable reasons. Much of the world remains unvaccinated, kids have generally been much less affected by the coronavirus, and we don't yet have a thorough understanding of the risks versus the benefits. Still, if we weigh all the pros and

New mathematical record: what's the point of calculating pi?
