German researchers have used scaffolded DNA origami to adjust the angle of a DNA hinge joint by altering the length of special “adjuster helices”, causing molecules attached to the sides of the hinge to be displaced by as little as 0.04 nm.

Each time a laser pulse actuates the cis-trans isomerization of a single carbon-carbon double bond, a single-molecule nanosubmarine made of 244 atoms is driven forward 9 nm against Brownian diffusion.
Building on previous work on single atom transistors and single atom qubits, Australian researchers have incorporated a quantum error correction code to make possible a scalable 3D silicon chip architecture that could lead to operational quantum computers.
Independent rotation of two wheels attached to either end of an axle has been achieved in a light-driven artificial molecular motor, suggesting a basis for a nanometer-scale transport system.
DNA nanotechnology produces an artificial molecular machine that changes shape when it encounters a specific antibody or other protein molecule, and emits light to signal the target’s presence.
A novel application of supramolecular chemistry allows molecules to join in only one direction, providing a new way to control the shape of large molecules.
A lipid bilayer supported by a mica surface assisted the mobile self-assembly of DNA nanostructures of various shapes into micrometer-scale 2D lattices.
A free to read online edition of the classic 3-volume physics text developed from Richard Feynman’s legendary Cal Tech physics lectures, specially designed for online reading, has been made available by the California Institute of Technology and the Feynman Lectures Website.
Prof. Art Olson discussed how we understand what we cannot see directly, how we integrate data from different sources, and how to develop software tools to move forward.
Optimized Geek podcast featured Christine Peterson on the future of nanotechnology, human lifespan, artificial intelligence, finding love, and other topics.
