When you go to the zoo, maybe you imitate the chimps, copying their faces, their gestures, or their walk. But it turns out the chimps imitate you just about as often—and as well, according to scientists. Other researchers have found that a trained nose can detect the odor of a single fly floating in a glass of wine. And that sometimes, a trip to the amusement park may be an effective treatment to aid in the passage of kidney stones.  

These projects are among the 10 selected by the editors of the Annals of Improbable Research to be honored at this year’s 28th first annual Ig Nobel Prize ceremonies. The prizes, awarded in September at Harvard’s Sanders Theatre, salute work that “first makes you laugh, and then, makes you think.”
