The 2023 Ig Nobel Prizes were awarded to ten winners this week. The award honors unusual or seemingly bizarre research that “makes people laugh … then think.” The prize, which was invented by Marc Abrahams, has a humorous and sometimes satirical approach but serious goals: promoting an interest in science in the general public, making research more accessible, and showing the relevance that even “strange” research can have. Marc Abrahams is Editor and Co-Founder of the Annals of Improbable Research, a former Editor-in-Chief of the Journal of Irreproducible Results.
Nobel Prize winners regularly present the Ig Nobel Prize—this year, the Chemistry Nobel Laureates Frances Arnold, Marty Chalfie, and Barry Sharpless (among other Nobel Laureates) took part in the ceremony, which was held in the form of an online broadcast. The winners explained their research, often in a very entertaining manner. The prizes come with prize money of 10 trillion dollars—Zimbabwean dollars from a time of extreme inflation, however—and the ceremony includes a traditional paper airplane-throwing section.
- Chemistry and Geology
Jan Zalasiewicz, for explaining why many scientists like to lick rocks . Licking rocks makes it easier to identify them in the field because mineral particles in rocks adhere better to a moist surface than to a dry one.”
Christine Pham, Bobak Hedayati, Kiana Hashemi, Ella Csuka, Tiana Mamaghani, Margit Juhasz, Jamie Wikenheiser, and Natasha Mesinkovska, for using cadavers to explore whether there is an equal number of hairs in each of a person’s two nostrils . The study could be helpful in treating patients with alopecia, a disease that causes hair loss. People with alopecia often lose their nose hair, which makes them susceptible to allergies and infections.
- Public Health
Seung-min Park, for inventing the Stanford Toilet, a device that uses a variety of technologies — including a urinalysis dipstick test strip, a computer vision system for defecation analysis, an anal-print sensor paired with an identification camera, and a telecommunications link — to monitor and quickly analyze the substances that humans excrete for health purposes [3–6].
Bieito Fernández Castro, Marian Peña, Enrique Nogueira, Miguel Gilcoto, Esperanza Broullón, Antonio Comesaña, Damien Bouffard, Alberto C. Naveira Garabato, and Beatriz Mouriño-Carballido, for measuring the extent to which ocean-water mixing is affected by the sexual activity of anchovies .
- Mechanical Engineering
Te Faye Yap, Zhen Liu, Anoop Rajappan, Trevor Shimokusu, and Daniel Preston, for re-animating dead spiders to use as mechanical gripping tools .
Homei Miyashita and Hiromi Nakamura, for experiments to determine how electrified chopsticks and drinking straws can change the taste of food .
Stanley Milgram, Leonard Bickman, and Lawrence Berkowitz for experiments on a city street to see how many passersby stop to look upward when they see strangers looking upward .
María José Torres-Prioris, Diana López-Barroso, Estela Càmara, Sol Fittipaldi, Lucas Sedeño, Agustín Ibáñez, Marcelo Berthier, and Adolfo García, for studying the mental activities of people who are expert at speaking backward .
Katy Tam, Cyanea Poon, Victoria Hui, Wijnand van Tilburg, Christy Wong, Vivian Kwong, Gigi Yuen, and Christian Chan, for methodically studying the boredom of teachers and students [12,13].
Chris Moulin, Nicole Bell, Merita Turunen, Arina Baharin, and Akira O’Connor for studying the sensations people feel when they repeat a single word many, many, many, many, many, many, many times .
