In Australia a woman gave birth to an incredibly rare set of semi-identical twins. Her egg did something a woman's egg is never supposed to do. Also, have we finally figured out why zebras have stripes? Would you believe it's to mess with bugs?

We like to think our phones are trusty companions, but instead they're sucking away our brain power and creativity - even when they're shut off. And maybe a tetanus shot doesn't hurt at all; we just talked ourselves into it. Pain can be raised or lowered just by how we think about it. Plus, all I can say is they better not kill off Tyrion Lannister on Game of Thrones. A new formula could predict it. Thanks to Harvard Business Review for the evil smartphone story. Science News for Students supplied information on our tolerance of pain. HuffPost had the fun story on surviving Game of Thrones. Thanks to Charlie Keaton for the NFN theme.
