Kevin Bullis reports in Technology Review: Now Paul Rothemund, a computer scientist at Caltech, with a background in biology, has developed a relatively inexpensive way to quickly design and build arbitrary shapes and patterns using DNA — and, he says, it’s simple enough for high-school students to use… It’s really spectacular work. I’m extremely excited about… Continue reading Do-It-Yourself DNA nanotechnology from Caltech
John Faith brings to our attention a writeup by Annalee Newitz over at io9.com which colorfully describes a new achievement by Foresight Feynman prizewinner Nadrian Seeman and team at NYU and Nanjing U.: Today in Nature, a group of researchers announced they’d successfully operated the first assembly line populated entirely by nanobots. The bots in question… Continue reading DNA-based 'robotic' assembly begins
Angela Belcher and team at MIT have tweaked a bacterial virus to serve as a scaffolding to: attract and bind with molecules of a catalyst (the team used iridium oxide) and a biological pigment (zinc porphyrins). The viruses became wire-like devices that could very efficiently split the oxygen from water molecules. Belcher says that within… Continue reading MIT's Belcher uses engineered virus to split water
One way to reach molecular machine systems is to get really, really good at protein engineering. If that’s your goal, you’ll want to be in Boston on May 17-21 for PEGS 2010, “the essential protein engineering summit”. Not sure if this is your pathway? Just reading the talk titles is educational. And they have great… Continue reading The protein engineering path to molecular manufacturing
See this article at New Scientist Real red blood cells owe their astonishing agility to their “biconcave” or tyre-like shape. To create synthetic particles with the same agility, Samir Mitragotri of the University of California and his team got their inspiration from the way real red blood cells acquire their final shape in the body.… Continue reading Not respirocytes yet, but …
Self-assembly of carbon nanotubes into two-dimensional geometries using DNA origami templates. Harnessing DNA origami to arrange CNTs.
Nanotechnology Enables Real Atomic Precision is the title of a piece by Susan Smith in Desktop Engineering, which includes comments by longtime Foresight Senior Associates Steve Vetter and Tihamer Toth-Fejel: While nanotechology might mean different things to different people, the term was originally coined to describe the building of things from the bottom up with… Continue reading Atomic precision as the goal of nanotechnology
Secrets of the Cell – Self-Destructive Behavior in Cells May Hold Key to a Longer Life – Series – NYTimes.com. Lysosomes are versatile garbage disposals. In addition to taking in shrouded material, they can also pull in individual proteins through special portals on their surface. Lysosomes can even extend a mouthlike projection from their membrane… Continue reading Secrets of the Cell – Self-Destructive Behavior in Cells May Hold Key to a Longer Life – Series – NYTimes.com
Longtime Foresight associates may remember Robert Birge, then of Syracuse, who spoke at the very first Foresight Conference in 1989. He has just won the Connecticut Medal of Science for his work in photoactive biochemicals. Story here (Hartford Courant).
Two recent publications provide more evidence of the growing capability of DNA scaffolds to support complex and interactive functions.
