A study that explores the feasibility of using pigeons to guide missiles and one that looks at the swimming abilities of dead fish were among the winners Thursday of this year’s Ig Nobels, the prize for comical scientific achievement.

Held less than a month before the actual Nobel Prizes are announced, the 34th annual Ig Nobel prize ceremony at the Massachusetts Institute of Technology was organized by the Annals of Improbable Research magazine’s website to make people laugh and think.

Winners received a transparent box containing historic items related to Murphy’s Law — the theme of the night — and a nearly worthless Zimbabwean $10 trillion bill. Actual Nobel laureates handed the winners their prizes.

“While some politicians were trying to make sensible things sound crazy, scientists discovered some crazy-sounding things that make a lot of sense,” Marc Abrahams, master of ceremonies and editor of the magazine, said in an e-mail interview.

The ceremony started with Kees Moliker, winner of 2003 Ig Noble for biology, giving out safety instructions. His prize was for a study that documented the existence of necrophilia in mallard ducks.

“This is the duck,” he said, holding up a duck. “This is the dead one.”

After that, someone came on stage wearing a yellow target on their chest and a plastic face mask. Soon, they were inundated with people in the audience throwing paper airplanes at them.

Then, the awards began — several dry presentations which were interrupted by a girl coming on stage and repeatedly yelling “Please stop. I'm bored.” The awards ceremony was also broken up by an international song competition inspired by Murphy's Law, including one about coleslaw and another about the legal system.

The winners were honored in 10 categories, including for peace and anatomy. Among them were scientists who showed a vine from Chile imitates the shapes of artificial plants nearby and another study that examined whether the hair on people's heads in the Northern Hemisphere swirled in the same direction as someone's hair in the Southern Hemisphere.

Julie Skinner Vargas accepted the peace prize on behalf of her late father B.F. Skinner, who wrote the pigeon-missile study. Skinner Vargas is also the head of the B.F. Skinner Foundation.

“I want to thank you for finally acknowledging his most important contribution,” she said. “Thank you for putting the record straight.”

James Liao, a biology professor at the University of Florida, accepted the physics prize for his study demonstrating and explaining the swimming abilities of a dead trout.

“I discovered that a live fish moved more than a dead fish but not by much,” Liao said, holding up a fake fish. “A dead trout towed behind a stick also flaps its tail to the beat of the current like a live fish surfing on swirling eddies, recapturing the energy in its environment. A dead fish does live fish things.”

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.

Scientists also discovered a spiny mouse, a squirrel, eight types of fish, three amphibians and 10 types of butterflies, Trond Larsen, head of Conservation International's Rapid Assessment Program, told Reuters this week.

He added that another 48 species found by investigators were potentially new, but needed further study.

The new species were found in Alto Mayo, a protected area with several ecosystems, Indigenous territories and villages.

"Discovering so many new species of mammals and vertebrates is really incredible, especially in such a human-influenced landscape as Alto Mayo," Larsen said.

The expedition between June and July 2022 was made up of 13 scientists plus local technicians and members of Indigenous groups.

"It was really fantastic to work so closely with the Awajun people. They have extensive traditional knowledge about the forests, animals and plants they live side-by-side with," Larsen said.

Among the new species, Larsen highlighted the spiny mouse that has stiff fur, the amphibious mouse, and a dwarf squirrel that measures 14 cm (5.5 in).

"(The squirrel) fits so easily in the palm of your hand. Adorable and beautiful chestnut-brown color, very fast," Larsen said. "It jumps quickly and hides in the trees."

Another favorite discovery was the blob-headed fish, a type of armored catfish, he said.

A total of 2,046 species were recorded during the 38-day expedition using camera traps, bioacoustic sensors and DNA sampling. Among them, 49 were classified as threatened, including the yellow-tailed woolly monkey and the tree monkey.

Larsen said the discoveries reinforced the need to protect the area.

"Unless steps are taken now to safeguard these sites and help restore parts of the landscape ... there's a strong chance they won't persist in the long term," Larsen said.
