Each year, Nikon's Small World In Motion competition invites scientists and curious observers alike to turn the lens inward — toward the invisible architecture of living things.

It is a reminder that the boundary between scientific documentation and human witness is thinner than we imagine, and that learning to see the very small is, in its way, a form of care.
