Foresight Update 23.09: Two-armed DNA nanorobot - February 26, 2009
The Weekly News Digest and Foresight Update newsletter have merged. Discuss these news stories at http://foresight.org/nanodot.
To use programmable nanomechanical manipulating devices to maneuver molecular building blocks it would be very helpful to array two or more devices in a molecularly precise arrangement with respect to each other. Structural DNA nanotechnology has now achieved this milestone with the demonstration that two independently controlled nanomechanical devices can be positioned on a two-dimensional DNA grid so that they can cooperate to capture between them one of four DNA building blocks, determined by which of two possible states each device is set to…
Advances in using amorphous metal alloys may make possible an inexpensive nanotech version of the molding technique used to make DVDs. The pits stamped in DVDs are rectangles 320 by 400 nm, but now amorphous metals have been used to stamp features as small as 13 nm, and the researchers believe that they can further decrease the feature size, perhaps to as small as single atoms…
This the fourth essay in a series exploring if, when, and how the Singularity will happen, why (or why not) we should care, and what, if anything, we should do about it.
Part IV: When
So when is all this going to happen? To quote Mark Twain, I'm gratified to be able to answer that question immediately:
Plant viruses are a new addition to the long list of types of nanoparticles being investigated as next generation nanotech cancer therapies…
Over at IEEE Tech Talk, Dexter Johnson points out a flurry of interest in "nanobots" over the past week, casting quite a wide net that ranges from Nadrian Seeman's experimental lab work to Ray Kurzweil's hopeful dreams for the far future. He also tosses a bit of credit in my direction — thanks! — and then proceeds to detail why he thinks all this interest has suddenly appeared…

Advancements in technologies such as nanotech, robotics, and biotech are promising to make major differences in our lives in the not-too-distant future, as the Industrial Revolution did to the agrarian world — to do for the physical world what the computer and Internet have done to the world of information.
Since 1986, the Foresight Institute has been in the forefront of a worldwide community of visionaries who work to help shape these possibilities into a positive, beneficial reality. If you would like to help us understand the potential of these technologies, and influence their direction, please consider becoming a member of the Foresight community. With your support, Foresight will continue to educate the general public on these technologies and what they will mean to our society.
