Scientists Reveal How "Molecular Boxes" Self-Assemble, Stretch to Fit Contents

Think back to your high-school biology class, where you learned about DNA. Deoxyribonucleic acid is the building block of life. It is present in each of our cells and determines countless physical traits. But this incredibly complex molecule is impressive for another reason: single strands can spontaneously connect with each other to form the familiar double helix structure.DNA isn't the only biological example of a self-assembling molecule, either: proteins and enzymes, the molecular machines t...
