Cockroach Milk, How to Blow Your Nose, and Mosquito Printers: The Ig Nobels of 2026

The 2026 Ig Nobel ceremony in Zurich recognized ten studies: a definition of kissing as “non-agonistic intraspecific oral-oral contact” across many species; evidence that higher socioeconomic status predicts greater unethical behavior in seven experiments; discovery that cockroach milk from Diploptera punctata is protein-rich and energy-dense; identification of the optimal single-nostril, forceful exhalation technique for nose blowing; quantification of bite probabilities for Bothrops jararaca when stepped on; and derivation of a low-angle impact that minimizes urinal splash.
