…Now researchers have been able to attach gold nanoparticles to DNA tiles and, by varying the size of the nanoparticles and the presence of DNA stem loops on some tiles, have been able to control the formation from the DNA tiles of various three dimensional DNA nanotubes in which the gold nanoparticles form stacked rings, single spirals, double spirals, or nested spirals along the length of the DNA nanotube…
Christian Joachim (who shared the Foresight Nanotech Institute Feynman Prize in the Experimental category in 1997 and won in the Theoretical category in 2005) is heading a group of researchers working to bring about atomic-scale computing…
Nanotech may provide a way to "bypass" faulty brain wiring. Research on the interactions between carbon nanotubes and neurons shows that electrical phenomena in nanotubes can be linked to neuronal excitability and may lead to engineering interactions between nanomaterials and neurons…
Molecular motors for early nanotech applications may be modeled on the various molecular motors found in biology. Using protein crystallography and electron microscopy, scientists have now revealed the working mechanism of one of the most powerful molecular motors known to biology…
Will realization of the seriousness of climate change push the development of molecular nanotechnology?
The answers of 151 thinkers and visionaries to the Edge Annual question for 2009 have been posted. The question: "WHAT WILL CHANGE EVERYTHING?" As phrased by John Brockman, Editor and Publisher, "What game-changing scientific ideas and developments do you expect to live to see?" In his answer, nanotechnology pioneer Eric Drexler points to a role for the imperative of sequestering carbon to ameliorate climate change in pushing the development of molecular manufacturing…

Do you believe that nanotechnology will give society the ability to tackle the hard challenges facing humanity? What's your priority for nanotechnology: cancer treatments and longevity therapies, sustainable energy, clean water, a restored environment, space development, or "zero waste" manufacturing? Or perhaps there are potential nanotech scenarios you would like to prevent.
If you would like to help influence the direction of this powerful technology, please consider becoming a member of Foresight Institute. With your support, Foresight will continue to educate the general public on beneficial nanotechnology and what it will mean to our society.
