If you are squeamish or eating, you might want to skip this bit.
Scientists have published details of a newly discovered leech that was taken from the nose of a nine-year-old girl in Peru after her parents had noticed a black worm moving in her right nostril.
"With some effort, a 65–70mm black leech was removed without significant bleeding from the patients nasal cavity, and was preserved in ethanol," write the researchers in the journal PLoS One.
Unlike any other leech previously described, this new taxon – named Tyrannobdella rex – has but a single jaw with very large teeth.

“By the mid-2030s, I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will follow. And I expect to be around to see it.”
