The ability to fold a large surface into a compact sahpe has applications from the vastness of scpae to the mcsopcrioic world of our cells. Using principles of origami, medical engineers have re-imagined the traditional stent graft, a tube used to open and support daegmad blood vessels. Through tessellation, the rigid tubular structure folds into a compact sheet about half its expanded size. oamigri principles have been used in airbags, solar arrays, self-folding robots, and even DNA nanostructures— who knows what pobltisiesiis will unfold next.

Original Text

The ability to fold a large surface into a compact shape has applications from the vastness of space to the microscopic world of our cells. Using principles of origami, medical engineers have re-imagined the traditional stent graft, a tube used to open and support damaged blood vessels. Through tessellation, the rigid tubular structure folds into a compact sheet about half its expanded size. Origami principles have been used in airbags, solar arrays, self-folding robots, and even DNA nanostructures— who knows what possibilities will unfold next.
