New computational methods to explore the rapidly expanding collection of high resolution three-dimensional RNA structures reveal new RNA structural motifs, identifying additional building blocks for complex RNA nanostructures.
A set of machine learning programs can now predict properties of small organic molecules as accurately as can calculations based upon the Schrödinger equation, but in milliseconds rather than hours.
Foldit game players have again out-performed scientists in protein design, this time improving the design of a protein designed from scratch to catalyze Diels-Alder cycloadditions.
A tutorial review available after free registration presents a theory-based exploration of the difficulty in moving from simple molecular switches to arrays of artificial molecular machines capable to doing substantial, useful external work.
RNA CAD tools developed for RNA-regulated control of gene expression in synthetic biology successfully engineered metabolic pathways in bacteria. Will engineering RNA-based genetic control systems lead to design tools for other RNA-based molecular machine systems?
A tutorial review addresses the distinction between the many simple artificial molecular devices that are currently available and truly effective artificial molecular machines that would mimic the ubiquitous molecular machines present in living systems.
In a lecture at Oxford Eric Drexler argued that atomically precise manufacturing will be the next great revolution in the material basis of civilization, and discussed how we can establish reliable knowledge about key aspects of such technologies.
Varying the length of the DNA used to connect the nanoparticles provides for a wide variety of nanoparticle sizes and crystal symmetries.
An algorithm helps design peptides that will self-assemble on a given surface to produce a supramolecular structure of desired geometry.
