The nanotechnology we were promised

A response to my “Parricide” essay has been seen on IEEE’s Tech Talk blog. Dexter Johnson gives a fair summary of the positions taken to date, and says As the argument seems to go, Drexler popularized the term nanotechnology in his book Engines of Creation, and so when the general public heard that thousands of… Continue reading The nanotechnology we were promised

Singularity, part 2

This the second 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 II: What is this thing called Singularity? Since I was trained, originally, as a mathemetician, I never really liked the term Singularity.… Continue reading Singularity, part 2

Nanotechnology Public Interest Group Appoints Dr. J. Storrs Hall President

The Foresight Institute has appointed Dr. J. Storrs Hall to the position of President.

Parricide

Once upon a time, or so the story goes, there was a young man who was hauled up before the court on charges that he had killed his father and mother. He readily confessed to the crime, but nevertheless pled for clemency: after all, he pointed out, he was an orphan. Recently on his blog… Continue reading Parricide

Can nanotechnology retard desertification?

The application is hydrophobic sand, which retains moisture near the roots of desert plants by virtue of a proprietary nanostructured coating on the grains of sand.

Singularity, part 1

This the first 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 I: The Singularity and its Discontents The concept of the Technological Singularity is so clearly part of the zeitgeist that it surely… Continue reading Singularity, part 1

Controlling bone-forming cells through nanotechnology

Nanotech may soon provide a solution for one of the more vexing problems in tissue engineering—how to control the differentiation of pluripotent or multipotent precursor cells into the specific cells needed to fix a specific problem.

Optimizing hierarchical protein design for nanotechnology

New computational results reveal how the proper hierarchical assembly of smaller protein domains optimizes mechanical properties.

Cool new nanocars

A new nanocar that runs cool — at room temperature — has been demonstrated by the research group of Stephan Link, colleague of James Tour at Rice. Tour won Foresight’s Feynman Prize last year for his earlier nanocar work. This press release describes several novel features of the latest work. In particular, the new cars… Continue reading Cool new nanocars

How to specify semiconductor or metallic graphene for use in nanotechnology

Computer simulations have shown that graphene deposited on a silicon dioxide surface will be either a semiconductor or a metal depending on whether the underlying layer is terminated with oxygen atoms or passivated with hydrogen atoms.
