Maria Ferrante seduces Daniel Rosenberg with a song about caffeine during "Chemist in a Coffee Shop: A Mini-Opera in 5 Acts" at the chemistry themed 21st annual Ig Nobel Prize Ceremony in Sanders Theatre on Thursday.

Twenty-three years ago, Darryl T. Gwynne of the University of Toronto and David C. Rentz, a retired entomologist, published a research paper on beetles and their attempts to mate with beer bottles on the side of the road in western Australia.

The beetles perceived the brown color and reflection of the beer bottles as characteristics of a giant female beetle and wasted sperm on failed efforts to mate with the glass products.

After decades of waiting, the scientists finally received the “serendipitous” biology prize during the 21st Annual Ig Nobel Prize Ceremony in Sanders Theatre Thursday night, Gwynne said.

“Personally, I think it’s good to communicate what I do as a scientist to non-scientists,” Rentz said. “And humor is a good way to do that.”

Hosted by the organization Improbable Research, the Ig Nobel Prize Ceremony honors scientific research that makes people laugh and think, according to the Improbable Research website. A satiric take on the Nobel Prize ceremonies, the Ig Nobel Ceremony invites Nobel laureates and other researchers to participate in a science-themed comedy performance.

The event was also co-hosted by the Harvard Computer Society, Harvard-Radcliffe Science Fiction Association, and Harvard-Radcliffe Society of Physics Students.

The theme of this year’s ceremony was “chemistry,” a word that prompted applause and whooping from the audience throughout the ceremony. Previous themes have included “bacteria” and “redundancy.”

Marc Abrahams, the editor of the Improbable Researchers’ Annals of Improbable Research magazine, served as the emcee for the evening.

“If you didn’t win an Ig Nobel Prize this year—but especially if you did—better luck next year,” Abrahams said at the end of the ceremony.

The ceremony also recognized researchers from Japan who found the ideal density of airborne wasabi and scientists from the Netherlands who found that people have a tendency to make fewer impulsive decisions when they have the urge to urinate.

“The award is also a recognition of creativity and originality, and that’s something that’s important to scientists,” said Mirjam A. Tuk, lead author of “Inhibitory Spillover: Increased Urination Urgency Facilitates Impulse Control in Unrelated Domains.”

After hearing about the event from his academic advisor, Ari D. Brenner ’14 volunteered to run the press desk for the ceremony.

“This show highlights scientific achievements that are pretty atypical,” Brenner said. “But I think it glorifies advancement in general. It’s also about sparking innovation for innovation’s sake.”

But not all attendees thought highly of the scientific achievements.

“I came to the ceremony because I wanted to see what not to do in science later in my life,” said Veronika Stelmakh, a third-year grad student at the Massachusetts Institute of Technology.
