Ig Nobel Prize
The Ig Nobel Prizes are satirical awards honoring achievements that “first make people laugh, and then make them think.” They have been presented annually since 1991 by the science-humor magazine Annals of Improbable Research.
The Wombat is the only animal known to make cube-shaped poop. In the last meter of its intestine, two stiff muscle bands contract unevenly to mold the feces into cubes. Cubes don't roll, so wombats stack them on rocks to mark territory. The discovery won a 2019 Ig Nobel Prize.
