The Ig Nobel Awards, which honor scientific achievements that "first make people laugh, and then make them think," have been presented for a range of unusual studies. The awards are given by the science humor magazine Annals of Improbable Research, which celebrates the unusual and honors the imaginative.
Diverse Research Recognized
Among the recognized research was a nearly 50-year-old study by Japanese researchers that measured the speed and amount of air expelled when people exhaled forcefully. The team from Wakayama Medical College aimed to provide instructions for those who "do not understand how to blow the nose," concluding that a "big and long" nose blow is most effective for clearing secretions. This work earned the Ig Nobel medicine prize, presented posthumously to lead author Dr. Tojuki Unno.
Another study awarded the olfaction prize came from German researchers who investigated the scents associated with different age groups. Their 2017 research, published in Chemosensory Perception, involved 235 parents rating the pleasantness of their children's body odor. The findings indicated that while young children were perceived as having a pleasant smell, this perception diminished significantly after puberty. The researchers suggested that the pleasant odor of young children might contribute to bonding and caretaking behaviors.
Social Dynamics and Economics
The Ig Nobel peace prize was awarded to scientists from Oklahoma State University for their research on friendship, published in Evolution and Human Behaviour. They discovered that individuals tend to value friends who display aggression towards people they dislike, noting that "people sometimes prefer friends who are more vicious than prosocial, for instance to one's enemies."
In the economics category, scientists were recognized for research showing that upper-class individuals are more likely to steal sweets intended for children. Their study found that when presented with a jar of candy labeled for youngsters, participants from higher socioeconomic backgrounds took more than those from lower socioeconomic backgrounds.
Biomechanics, Biology, and Physics
A study on the evolution of kissing, published earlier this year, received the biomechanics prize. The paper provided a definition of kissing as "non-agonistic interactions involving directed, intraspecific, oral-oral contact with some movement of the lips/mouthparts and no food transfer." The research also presented evidence suggesting that humans may have been kissing Neanderthals as far back as 50,000 years ago.
The biology prize recognized academics who gently stepped on venomous snakes to understand what provokes them to bite. The chemistry prize went to researchers who found that milk proteins derived from cockroaches contain three times the energy of milk proteins from cows.
Technology, Physics, and Soil Science
Using 3D printing to recreate a mosquito proboscis earned the technology prize. The physics prize was awarded for attempts to design a splash-free urinal. A 2022 device developed by a team from the University of Waterloo was designed to prevent urine splash-back.
Finally, the soil science prize was given to researchers who buried 1,000 identical pairs of underpants in over 25 countries and then excavated them two months later. This project aimed to assess soil health by examining the decomposition of the undergarments, providing insights into the soil's microbial inhabitants and overall condition. The team from the University of Zurich stated their hope that this sensory experience would encourage participants to view soil as a living system and a vital resource.
Winners of the Ig Nobel prizes are traditionally handed their awards by genuine Nobel laureates and are subsequently showered with paper airplanes.
