ZURICH - The late Japanese researcher Tokuji Unno won this year's Ig Nobel Prize in medicine on Thursday for his study on how to blow one's nose.

The achievement, recognized at a ceremony in Zurich, marks the 20th consecutive year in which at least one Japanese national has been among the winners selected by the Annals of Improbable Research, a science humor magazine that has given out the annual awards since 1991, parodying the prestigious Nobel prizes.
