Origami stories

 
Origami paper folding has long been a traditional art form, but now researchers at the University of Texas at Austin have been inspired to use paper folding as a way to test for diseases. The idea expands on existing paper sensor tests, but the folding allows it to detect more complex substances and diseases.
 
You and I may consider it cheating, but Harvard's Robert Wood and his team have slapped a bunch of tiny actuators onto pieces of origami paper and have taught it to bend itself into different shapes. What could that even be good for, though?
