A slate of spoof science prizes that don’t target breakthroughs, but instead focus on research achievements that "make people laugh, and then make them think," will be awarded Thursday evening.

The 23rd Ig Nobel Prize ceremony, an evening of scientific comedy, will take place at 6 p.m. ET at the Sanders Theatre at Harvard University in Cambridge, Mass., and will be streamed live online.

Ten awards will be handed out by winners of the prestigious Nobel prizes at sold-out event that will feature 60-second lectures about the winning research and entertainment that includes a "Date-with-a-Nobel-Laureate" contest and a "mini-opera" called "The Blonsky Effect."

The awards are organized annually by Improbable Research, an organization that says its goal is to spur people’s interest in science, medicine and technology.

Last year’s winners included a team that studied how chimps recognize each other from their behinds, and the inventors of a device that disrupts a person’s speech by making them hear their own spoken words delayed by a few hundred milliseconds.

The ceremony is co-sponsored by the Harvard-Radcliffe Society of Physics Students and the Harvard Radcliffe Science Fiction Association.

In addition to the awards ceremony stream, Improbably Research says it is providing an additional "behind-the-scenes" stream this year called the "Ig Nobel Courtesy Cam" for the benefit of the U.S. National Security Agency and other intelligence agencies.
