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.”

Rare Amur Tiger Cubs Debuting at Minnesota Zoo Raise Hopes for This Species

A pair of rare Amur tiger cubs are making their public debut at the Minnesota Zoo, raising hopes for preserving an endangered species that’s native to far eastern Russia and northern China.

Andrei and Amaliya got to venture outside and feel the grass of their new home under their paws Wednesday for the first time since their 12-year-old mother, Dari, gave birth on May 23, The AP reported.

“They’ve done quite well since then,” zoologist Trista Fischer said. “We’ve monitored them very closely. Dari’s been fantastic. She’s provided outstanding maternal care. And so today we’ve reached the point where they’re fully vaccinated and they’re now about 40 to 45 pounds (18-20 kilograms).”

Scientists estimate the Amur tiger population is just around 400 to 500 in the wild. They were near the brink of extinction in the 1930s and 1940s but have recovered somewhat since then. It’s tricky to breed them, and around one in four Amur cubs don’t make it to adulthood, whether it’s in the wild or in captivity, she said. Poachers are another major threat.

But the Minnesota Zoo, located in the Minneapolis suburb of Apple Valley, has a long history of conserving tigers. Its Amur tigers have produced 57 cubs, 46 of which survived for at least 30 days. Of those 46, 21 have gone on to produce litters of their own, amounting to another 86 cubs. The births of Andrei and Amaliya raised the zoo’s population to seven Amur tigers, including their sire, Luka.

Fischer is the leading coordinator for the Tiger Species Survival Plan, a breeding program in the United States with facilities in other countries that works on a global level to preserve the big cats. The plan manages three groups of tigers: Sumatran, Malayan and Amur.

“This litter is so valuable to the population right now,” she explained, saying the genetic diversity of heathy tigers in human care could someday be used to help support populations in the wild.

Zoo spokesperson Zach Nugent said the cubs will remain housed together with their mom for about 18 months, before Andrei, the male, is moved to separate housing, around the same time a male cub in the wild would start venturing out on his own. Amaliya, the female, may spend a little more time with Dari, up to 24 months. Then Fischer will determine whether either cub should be bred, and potentially moved for that to another accredited zoo, which typically happens after the cubs are 2 years old.

“Aww, I love when they get their little Yoda ears,” Fischer said referring to the pointy ears of the Star Wars character as she watched Amaliya and Andrei explore the new terrain of their enclosure. She said it was an emotional, exciting and proud moment for her and her team.

“Our work’s not over, but all that work so far is really paying off in how well that these cubs are acclimating to a new surrounding, pretty much immediately,” she said as the little tigers roamed outside with their mother. “They’re showing a lot of resiliency, which is something that we work hard for in human care. We want these animals to have a lot of confidence and be able to adapt to new environments just as they’re doing today.”
