Our most popular science stories this year covered a really broad range of topics. Your favorites included stories on cat behavior, quantum mechanics, black holes, absurd creatures, traffic, maps, and blood tests.
Some of the top stories looked at how reading on a screen instead of paper affects your brain, what you should and shouldn't worry about when it comes to Ebola, a mission to land on a comet, and a 50-foot-long snake. We're proud of these stories, and we're glad you liked them too.
