Free online edition of The Feynman Lectures on Physics

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.

Conference video: New Methods of Exploring, Analyzing, and Predicting Molecular Interactions

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.

Foresight co-founder on the future of the human lifespan

Optimized Geek podcast featured Christine Peterson on the future of nanotechnology, human lifespan, artificial intelligence, finding love, and other topics.

Nanotechnology carries gene editing package into cells

Hijacking a viral method of replicating circular genomes, ball-of-yarn-like DNA clews are used to transport the protein and guide RNA molecules needed for gene editing into the cell nucleus.

DNA nanotechnology guides assembling cells into ‘Organoids’

DNA strands decorating cell membranes like ‘Velcro’ program the adhesion of cells to other cells or to extracellular matrices to build tiny tissue models.

Catalytic micromotors demonstrate carbon dioxide removal from water

A micromotor covered with the enzyme carbonic anhydrase zips through water rapidly converting dissolved carbon dioxide to the bicarbonate ion, which can then be precipitated as calcium carbonate.

Atomically precise boron doping of graphene nanoribbons

The ability to dope graphene nanoribbons with boron atoms to atomic precision opens a range of possible new applications, from chemical sensing to nanoelectronics to photocatalysis to battery electrodes.

Parallel to protein folding improves DNA origami process

Designing a small DNA origami that can fold in several almost equivalent ways demonstrates how understanding and guiding the folding pathway can improve the efficiency of the folding process, potentially leading in more complex situations to higher yields of the desired nanostructure and fewer misfolded structures.

Review of artificial molecular machines and their controlled motions

An extensive review of artificial molecular machines, their large-amplitude motions, and the changes these motions produce, emphasizes small molecules and the central role of chemistry in their design and operation.

Conference video: Bringing Computational Programmability to Nanostructured Surfaces

Dr. Alex Wissner-Gross surveyed the interplay between programmability of bits and atoms in the development of technology, asking how the recent successes with programming bits can help nanotechnology progress in programming atoms.
