Researcher discovers a potential new species in his nostril
I really don't want to make a bad joke here about it being right under his nose this whole time!, but the fact remains that Tony Goldberg, of the University of Wisconsin at Madison, is pretty sure that the tick he picked out of his nostril after a trip to Uganda is an entirely new species.
From Popular Science:
Goldberg was studying the spread of diseases in the jungles and highlands of Kibale National Park, in western Uganda. When he got back to the states, he realized that there was a tick attached to the inside of his nostril--alarming, even for a scientist who studies ticks, if not terribly surprising. There are a few kinds of ticks, localized to that part of Uganda, that are known as "nose-ticks." Primarily of the genus Amblyomma, these ticks aim for the nose.
Goldberg extracted the tick and sent it in for DNA sequencing, which would tell him what sort of tick it was. And he found that it didn't match any other tick in his database--meaning either this kind of tick hasn't had its DNA sequenced, or it's a completely new species.
