From Stephanie Warren:

Want an excuse to eat more delicious, garlicky foods? (I do.) Scientists have found that garlic has amazing antibacterial qualities. When they mixed garlic extract with E. coli, the garlic swiftly dismantled the bacteria.

All cockroaches have exoskeletons made up of chitin. In New York City, it makes them dull brown. But in Costa Rica, it makes them…silver and gold. How does this work?

This video shows how ant swarms can move like liquids. Whoa.


From Sarah Fecht:

The Civil War was tough, but the one thing that thrived amongst the violence was facial hair.  Vote for your favorite here.
