Sorry to disappoint, but science writer Carl Zimmer says we're not going to bring back dinosaurs. But, he says, "science has developed to the point where we can actually talk seriously about possibly bringing back more recently extinct species."
It's called "de-extinction" — and it's Zimmer's cover story for National Geographic's April issue.
Francois Brunelle is a French Canadian photographer whose work gives new meaning to the phrase "double exposure."
For the past several years, Brunelle has been documenting doppelgangers — people who happen to look strikingly similar but aren't related. He's on a quest to make 200 black-and-white portraits, and plans to eventually turn the project into a book.
