BOSTON (AP) — A team of researchers from Japan wondered if painting cows with zebralike stripes would prevent flies from biting them. Another group from Africa and Europe pondered the types of pizza lizards preferred to eat.

Those researchers were honored Thursday in Boston with an Ig Nobel, the prize — a hand made model of a human stomach — for comical scientific achievement. In lieu of a big paycheck, each winner was also given a single hand wipe.

“When I did this experiment, I hoped that I would win the Ig Nobel. It’s my dream. Unbelievable. Just unbelievable,” said Tomoki Kojima, whose team put tape on Japanese beef cows and then spray painted them with white stripes. Kojima appeared on stage in stripes and was surrounded by his fellow researchers who harassed with cardboard flies.

As a result of the paint job, fewer flies were attracted to the cows and they seemed less bothered by the flies. Despite the findings, Kojima admitted it might be a challenge to apply this approach on a large-scale.

The year’s winners, honored in 10 categories, also include a group from Europe that found drinking alcohol sometimes improves a person’s ability to speak a foreign language and a researcher who studied fingernail growth for decades.
