Happy Thanksgiving From PopSci!

The PopSci staff will be out of the office the rest of this week so we can spend some time with our families. (We'll miss you, too.) In the meantime, enjoy our favorite posts from this week.

(Those who would rather not leave things to chance and just pony up some cash for the T-shirt can do that here.) The stories pictured herein:
