CAMBRIDGE, Mass. - An experiment that proved people who think they are drunk also think they are attractive and another that showed lost dung beetles can use the Milky Way to find their way home are among the winners of this year's Ig Nobel awards.
The awards recognize weird and humorous scientific discoveries.
Actual Nobel laureates were at Harvard University on Thursday to announce the 2013 winners.
Annals of Improbable Research, the science humor magazine that organizes the awards program, said the point is to make people laugh and then think. The winners come from all over the world.
The awards ceremonies are usually silly, and this year's awards were no different. It included a mini-opera and a contest to win a date with a Nobel laureate.
The winners will give speeches Saturday at MIT.
