Oddly, origami could be useful for snagging prey.
A single-celled protist called Lacrymaria olor uses a helix of pleats folded like origami to unspool a necklike protrusion up to 30 times the length of its body, or 1.2 millimeters, to quickly snap up food, researchers report in the June 7 Science. If a roughly 1.7-meter-tall person could do the same, their neck would reach about halfway up the Statue of Liberty.
The finding could help inspire new robotics, such as tools for microsurgery that can extend and contract inside small body cavities.
