After returning from an African research expedition, pathobiology professor Tony Goldberg found an unexpected stowaway: a tick hiding up his right nostril. ?When you first realize you have a tick up your nose, it takes a lot of willpower not to claw your face off,” Goldberg, a University of Wisconsin?Madison researcher, says in a statement. But Goldberg managed to retrieve the tick from his nostril and send it off for analysis, leading him to not just discover a potentially new species of tick, but what could also be a new explanation for how diseases spread between chimps and humans.
