This stuff is amazing... Why did I have to find it while dealing with a migraine??

Description: Centola et al designed and characterized a leaf-spring nanoengine (NE) which consists of two 18-helix bundle DNA origami arms connected at one end by a flexure made up of a layer of dsDNA and a layer of ssDNA. A T7 RNA polymerase connected to one of the arms binds to a promoter sequence on a dsDNA bridge connecting the two arms and as it consumes NTPs, drives the structure closed. The tension built up in the flexure then re-opens the structure, preparing it for another cycle.

Structure type: Nucleic acid/protein hybrid

Applications: Molecular machines, Molecular motor, DNA robot, DNA nanotechnology

On Jan. 1, 2019, New Horizons made a high-speed flyby of Arrokoth, approaching as close as 2,198 miles (3,538 kilometers) of the object. During the encounter the spacecraft's cameras revealed a world not quite like any explored before. In a fitting tribute to the farthest flyby ever conducted by spacecraft, the Kuiper Belt object 2014 MU69 has been officially named Arrokoth, a Native American term meaning “sky” in the Powhatan/Algonquian language.
