Study: Desert ants display a sophisticated sense of direction
SmartBrief on Leadership | Jan 23, 2017
Ants must often drag their food back home while walking backward, and research suggests they are able to do so because they know their destination, internalize visual cues and take direction from the sky. This suggests "a representation of direction and of space that is much more sophisticated than we thought," says Antoine Wystrach, one of the study's authors.

SmartBrief on Leadership | Jan 16, 2017
The Canadian linguistic tic of "eh" isn't totally understood, but most say it's a tool for noting mutual understanding, writes Dan Nosowitz.

Ancient civilizations and monarchs loved to concoct poisons, and the delight in playing with antidotes, or theriacs, continued for centuries before any regulation began to emerge, writes Carly Silver.

This universe is complicated enough, much less the multiverse
SmartBrief on Leadership | Jan 06, 2017
The idea of the multiverse can be difficult to comprehend, not to mention controversial, even for the physicists who spend their lives exploring the edges of our universe and these potential other universes. "How do I pretend I have no problem accepting the fact that infinite copies of me might be parading around in parallel worlds making choices both identical to, and different from, mine?" writes Tasneem Zehra Husain, a theoretical physicist.
There's more to rainbows than we understand

Looking at America through Disney's eyes
SmartBrief on Leadership | Jan 04, 2017
Disney's sense of optimism has been important in American history since at least World War II, and it's not because of strict accuracy in Disney's depictions, writes Bethanee Bemis. "The importance of 'Disney's American history' is in how it gives life to a folk history we would like to have, one that gives us a sense of optimism and unity," Bemis writes.

Photographer Cassandra Zapini's photos of Americans commuting in New York, Chicago and Boston are on display here.
