Structural DNA nanotechnology predates RNA nanotechnology by a decade or more, and one of the key developments in building more complex nanostructures and devices from DNA has been DNA origami. So, what might we expect from last summer’s introduction of RNA origami?”
NANOTECHNOLOGY UPDATE: Automated synthesis expands nanotechnology building block repertoire. “The main limitation right now is that only 200 building blocks are available that carry both the halogen and the boronate groups, so only these can be used anywhere other than the first or last building block in the chain. If several thousand new building blocks become commercially available, it may not be too much of an exaggeration to talk about 3D printing of small molecules. . . . t will no doubt take several years to see just how big, how diverse, and how complex the products of this molecule synthesizer can be. It seems reasonable to expect a huge effect on drug discovery and other practical areas. Will it contribute to the development of APM? For example, could it synthesize small diamondoid parts? Could it produce useful catalysts or other functional components to attach to a large structural DNA framework? Or perhaps components for smaller, stiffer structural frameworks?” Faster, please.
Microscopic drones which can seek outand repair sections of artery damage could signal the future of treatments for heart disease and strokes, scientists claim.
Successful tests of the nanodrones have been carried out in mice – and researchers hope to conduct the first human trials soon.
The tiny particles are 1,000 times smaller than the tip of a human hair, and are designed to latch on to atherosclerotic plaques – hard deposits made from accumulated fat, cholesterol and calcium that build up on the walls of arteries and are prone to rupture, producing dangerous clots.
Once they have attached, they release a drug derived from a natural protein which can repair damage in the body.
In the mice, scientists found that just five weeks of treatment resulted in significant repairs to artery damage while the plaques were shrunk and stabilised, making it less likely for fragments to break off and cause clots.

I AM, AS MOST READERS KNOW, GENERALLY A TECHNO-OPTIMIST. But mocking Elon Musk for his fears about Artificial Intelligence is silly.
The article might have interviewed James Miller for more on what Musk is talking about. Here’s my interview with Miller. Says Miller about strong AIs: “I think the default path is that they treat us horribly.” Also, “gray goo” isn’t a AI-gone-bad scenario, it’s a nanotechnology-gone-bad scenario, and a somewhat exaggerated one.

An article at KurzweilAI.net presents news from UC Davis of a ‘nanoporphyrin’ platform for developing multifunctional nanoparticles based upon treelike dendrimer structures made using porphyrin, cholic acid, amino acids, and polyethylene glycol.”
Civilian technology, Joel Mokyr notes, has also gone “small” — nanotechnology, genetic engineering, custom-engineered materials, “mass customization” through 3-D printing. If the Rouge plant looming over Dearborn was the iconic symbol of the industrial age, the iconic symbol of our information age is the smartphone in your pocket.
“Large” technology requires the standardization of masses of people, centralized command-and-control, conformity to social norms. Massive work forces and massive armies cannot operate optimally otherwise.
“Small” technology enables individuals to make personal choices, fashion their world to their own dimensions, deploy their own talents and pursue their interests in ways of their own choosing. Standardization yields to customization.
President Obama doesn’t seem to get this. He sees history as a story of progress from minimal government to ever-larger government. He’s only sorry that he hasn’t taken us farther on that track.
But history doesn’t proceed in a straight line; it moves around. “Large” technology made big government seem necessary in 1914. “Small” technology requires something different, something more adaptive today.
Indeed. You could almost write a book about that.

OBJECTIFIED BY SOCIETY’S ARTIFICIAL STANDARDS: Hollywood Actors: Six-Packs That Speak Lines.
Via Outside the Beltway, I see that Men’s Journal has a lengthy article on what it takes to be a male movie star these days. The short answer: 3 to 4 percent body fat, an incredibly carved six-pack and lovingly sculpted musculature. Because that combination does not normally occur in nature, the long answer involves nutritionists, traveling weight trainers, and more-than-occasional injections of testosterone and human growth hormone.
In other words, a Hollywood star is not so much an actor, or a body. It is a nearly starving body that has been stripped of almost all its naturally occurring subcutaneous fat, then artificially bolstered with various supplements and medical technology to make it look like a statue rather than a famine victim.
Nanotechnology will take care of that, eventually, at which point, not being difficult and rare, the look will go out of style. Meanwhile, I’m reminded of this article from back when Salon didn’t suck.

NANOTECHNOLOGY UPDATE: Nanomotors are controlled, for the first time, inside living cells.
NANOTECHNOLOGY UPDATE: Nanoparticle pinpoints blood-vessel plaques: A step toward identifying plaques vulnerable to rupture that causes heart attack and stroke. “By loading the surface with gadolinium ions instead of injecting them and letting them flow freely in the blood stream, the nanoparticle increases the relaxivity — or contrast from healthy tissue — by more than 10,000 times. That’s because the nanorod carries up to 2,000 molecules of the contrast agent, concentrating them at the plaque sites. Secondly, attaching the contrast agent to a nanoparticle scaffold reduces its molecular tumbling rates and leads to additional relaxivity benefit, the researchers explained. While the view is better, they are able to use 400 times less of the contrast agent because it’s delivered directly to plaques.”
