Glasses for the praying mantises

Suzanne Kaiser, Feature Reporter

A few weeks ago, scientists at the University of Zurich came up with the crazy idea of outfitting praying mantises with miniature 3D glasses for the sake of testing.

The tests were rather simple. The praying mantises were placed into a tiny theater and shown a video with moving shapes. Next, the insects were shown the same video, except this time they were wearing their 3D glasses.

As researchers predicted, the bugs reacted only while the glasses were on.

Why do bugs need 3D glasses? To help scientists figure out brand new things.

And why do we care if the praying mantises react to a three dimensional video? Because that can also lead to new advances.

Some things that scientists hope to figure out through testing these insects include cameras that actually have depth perception and new computer algorithms.
