Watch the announcement of this year's Ig Nobel Transportation Prize, awarded to a Cornell-led team for their research on whether it's safer for rhinos to be transported upside-down or on their side.  

In an effort to save endangered rhinos, Cornell researchers and Namibian colleagues found that transporting rhinos upside down from helicopters was safe and quick.

To keep rhinos safe from poaching and to distribute individuals across habitats, management teams must often tranquilize rhinos in remote areas that cannot be accessed by roads — this often leaves one option: airlifting them out via helicopter.
