Description

A large team of scientists maps how the human vault particle flexes in a paper from 2026. Vaults are huge barrel-shaped complexes found in many cells, yet their job is still unclear. Each vault is built from two matching half shells with a roomy hollow inside. That hollow hints at a transport role, which would require the shell to open and close.

Sharp microscope images revealed two states of the particle, one symmetric and one not. Computer simulations showed breathing motions and porous surfaces in both states. Breaking key contacts between the halves reduced shell assembly in tests. The authors say these contact points explain the vault's flexibility.
