From the world of amazing research: Belly-button fluff. The research of the Austrian researcher Steinhauser has revealed what belly button fluff is made of, and how come it migrates to the belly button. It turns out that it is avoidable, you just have to shave your belly, alternatively get a belly-button piercing. Knowing that the main carrier of belly button fluff is an overweight, middle-aged male, the image of shaved bellies and pierced belly buttons is perhaps slightly disturbing.
Georg Steinhauser does not only stare at bellies though. From the Technical University of Wienna, 2008, a report of his research on the chemical fingerprint of volcanic eruptions through studies of pumice.
