What a fascinating week it’s been for National Geographic readers, with our top stories ranging from a rare health disorder on the rise for cannabis users to a controversial new theory about the fall of the Roman Empire. Our top story is one all of us will find useful, but don’t miss other favorites like the new tarantula species named for its giant genitals or the World War II treasure hunters on a rugged Greek island.
