New Origami-inspired Design Turns Pushing Into Pulling  

The series of paper cells developed by researchers at the University of Washington uses origami folds to absorb the force of impacts. (Credit: Kiyomi Taguchi/University of Washington) Whether applied to auto collisions or rocket landings, absorbing energy from impacts is a valuable trait, and industries have been working on various solutions for years. For spacecraft, landing safely has entailed everything from inflatable airbag systems to sky cranes to retro-thrusters. But what if the
