Researchers in Australia and the US have demonstrated a working transistor by placing of single atom of phosphorous with atomic precision between gates made of wires only a few phosphorous atoms wide. This demonstration points to possibly extending current computer technology to the atomic scale.

Scientists at Kyoto University and the University of Oxford have combined DNA origami and DNA motors to take another step toward programmed artificial molecular assembly lines.
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.
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.
A green nanotechnology roadmap released by the American Chemical Society describes the opportunities and barriers to developing commercial applications of nanomaterials that present little threat of harm to health and the environment, and concludes with an action agenda to more forward.
A bacterial virus called M13 was genetically engineered to control the arrangement of carbon nanotubes, improving solar-cell efficiency by nearly one-third.
New software for scaffolded DNA origami makes it easier to predict what shape will result from a given DNA template.
Phage-assisted continuous evolution of proteins is roughly a hundred times faster than conventional laboratory evolution of proteins, perhaps speeding the development of components for molecular machine systems.
Using proprietary block co-polymer technology, directed self-assembly allows adding block co-polymers that assemble themselves into regular arrays on the surface of a silicon wafer that had been patterned using lithography.
Researchers in the UK and Japan use atomic force microscopy to visualize a DNA molecular robot moving along a 100-nm DNA track.
Here we present a special report from Dave Conz of ASU on Josh Hall’s talk and subsequent panel discussion at the SME nanotech conference. An excerpt: Technoscientific development is difficult to direct and nearly impossible to predict. Because of this – not in spite of it – panel discussions like “How Do We Get There [...]
PhysOrg.com brings news and a video of a new 3D patterning technique from IBM that reaches down to 15 nm resolution which “could go even smaller”: IBM Research in Zurich has demonstrated a new nanoscale patterning technique that could replace electron beam lithography (EBL). The demonstration carved a 1:5 billion scale three-dimensional model of the [...]
One of the species of early hominids is named Homo habilis, meaning “handy man,” after their significant advancement in tool use over previous hominids. One of the goals of the AGI Roadmap is to chart paths to full human intelligence, and one of the paths might follow the one that evolution took. The Wozniak Test, [...]
Foresight’s mission is essentially an educational one. In simplest terms we are here to point out foreseeable technological developments that not only will make the future different from the past, but make it different in ways that aren’t obvious and which everyone isn’t already planning for. Nanotechnology — true nanotech in Drexler’s original sense of [...]
Accelerating Future » RepRap “Mendel” to be Released Soon!. Nicw round-up with videos of the latest in the Rep-Rap world.
There’s an excellent round-up over at Next Big Future on the Roadmap for Additive Manufacturing. This is solid freeform fabrication, 3-D printing, stereolithography, rapid prototyping, and so forth. In the long run, 3-D printing is one of the more straightforward paths to full-fledged nanotech with mechanosynthesis. Mechanosynthesis might be seen simply as the ultimate in [...]
One of the major problems for micromachines, much less nanomachines, is wear. The phenomenon of stiction combines the two worst aspects of surface-to-surface interaction — a high coefficient of friction and a locally-generated high applied force — to cause enormous problems. At the very smallest scale, once we gain complete control over atomic configuration, superlubricity [...]
There’s a nice article over at the Singularity Hub that’s a round-up of currently-available haptics devices. They seem primarily excited over the prospects of haptics in gaming, but there are two reasons we’re interested in developments. First is simply telerobotics, as in Feynman Path manipulation. We want the feedback to help develop an intuitive feel [...]
Engineering and analysis in the field of SRMs is unusual in many ways. Eric Drexler has posted a paper about differences in evolutionary capacity in mechanical and biological systems that’s worth a look. Purely coincidentally, we at Foresight have been discussing self-replication in the context of the Feynman Path and I came up with an [...]
