Femtocomputing

My goal in this essay is an ambitious one: to show how the properties of quarks and gluons can be used (in principle) to perform computation at the femtometer (i.e. 10^-15 meter) scale. This is admittedly highly speculative and theoretical material -- but it's all within the domain of science, and given the reality of exponential advance, may well become practical technology sometime in this cent...

Why We Could All Use a Heavy Dose of Techno-optimism

Why We Could All Use a Heavy Dose of Techno-optimism

At a recent TED Conference, a dinner was organized by the Edge Foundation, a think tank and nonprofit that celebrates big ideas. The theme of the evening was the "New Age of Wonder," and the discussion drew comparisons to the Romantic Age, the period between 1770 and 1830 when science and art were friends. It was a time when astronomers and poets were in some ways indistinguishable, as artists wer...

Toward Intelligent Nano Factories and Fogs

Computer scientist and futurist thinker J. Storrs Hall has been one of the leading lights of nanotech for some time now.  Via developing concepts like utility fog (see the figure below) and weather machines, he has expanded our understanding of what nanotech may enable.  Furthermore, together with nanotech icon Eric Drexler he pioneered the field of nano-CAD (nano-scale Computer Ai...

There’s Plenty More Room at the Bottom: Beyond Nanotech to Femtotech

There’s Plenty More Room at the Bottom: Beyond Nanotech to Femtotech

Not long ago nanotechnology was a fringe topic; now it's a flourishing engineering field, and fairly mainstream.  For example, while writing this article, I happened to receive an email advertisement for the “Second World Conference on Nanomedicine and Drug Delivery,” in Kerala, India. It wasn't so long ago that nanomedicine seemed merely a flicker in the eyes of Robert Freitas ...

Top Five Transhumanist Fantasies

1. Eternal Life Through Data Storage In many respects the Holy Grail of transhumanism, many transhumanist authors and artists have imagined a future in which the human being is essentially immortal via the capability to upload memory, personality, and consciousness into a database and then reload this information into a new body when a person dies.

Nanolithography: Another Step Forward

Nanolithography: Another Step Forward

NanoInk, a company that has a line of nanolithography products for biological material, including the NLP 2000 system, has announced a new method of nanopatterning based on PEG hydrogels that enhances the machine’s lithographic skills. Nanolithography is like having a molecular pen that can write on nanoscale material.  PEG, which stands for polyethyl glycol, is a polymer tha...

How will Nanoparticles and The Human Body Get Along?

Many of the predicted future benefits arising from advances in neurotechnology and other transhuman developments are grounded in the continuing success of research in the broad field of nanotechnology. A particularly critical aspect of this research is the development of nanoparticles that would independently operate inside the human body.  A lot of research is already underway...

Targeting Artificial Implants Using Nanotech

Lund University in Sweden announced last week that they have successfully targeted artificial implants in a pig by using magnetics to direct therapeutic nanoparticles.   Henrik Kempe and Maria Kempe (brother and sister) surface-coated an anti-clotting drug with magnetite nanoparticles and used an external magnet placed over an implanted artery stint.
