The winners of the 2021 Ig Nobel Prize have been announced including an analysis of purring in cats, the measurement of odors in the cinema produced in reaction to scary or emotional scenes, and the evolution of beards as protection against face-punching.

The ceremony was held online for the first time and continued the tradition the awards have for honoring some of the funniest, yet still thought-provoking research of the previous year.
