…two basic structural motifs of DNA nanotechnology have been efficiently and inexpensively replicated in bacterial cells. The fact that these artificial DNA nanostructures are tolerated in living cells was surprising, and may open new avenues for synergism between nanotech and synthetic biology…
Nanotech pathways to a sustainable energy economy are generating a great deal of interest in Europe…
Combining a nanotech method of getting genes inside cancer cells with genetic engineering of a potent suicide gene driven by control signals that are very active only in cancer cells effectively killed cell lines derived from pancreatic cancer, a deadly cancer for which there is currently no effective treatment…
A group of German scientists have developed a new slant on DNA nanotechnology by using atomic force microscopy to assemble a DNA scaffold on a surface to which molecular building blocks can then bind. The pattern of molecular building blocks thus assembled can be arbitrarily complex, with individual building blocks spaced about 50 nm apart…
The design of a novel protein whose catalytic activity is controlled by light may or may not have direct nanotech applications, but it represents another milestone in engineering proteins. In this case scientists were able to engineer functional communication between two unrelated proteins by taking advantage of the fact that each protein exhibits allosteric regulation…

November 15-16, 2008
On November 15-16, 2008, the world's most dangerous ideas will collide in Mountain View, California. Convergence08 examines the world-changing possibilities of NANOTECH and the life-changing promises of BIOTECH. It is the premier forum for debate and exploration of COGTECH ethics, and ground zero of the past and future INFOTECH revolution. Convergence08 is an innovative, lively unconference, the first and only forum dedicated to NBIC (Nano-Bio-Info-Cogno) technologies
For more information, see the press release. This event will serve as Foresight's Vision Weekend for 2008.

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 Nanotech Institute. With your support, Foresight will continue to educate the general public on beneficial nanotechnology and what it will mean to our society.
The Singularity Summit
Hosted by the Singularity Institute, the Singularity Summit is the premier dialog on the Singularity.
The Singularity Summit gathers the smartest people around to explore the biggest ideas of our time. Learn where humanity is headed, meet the people leading the way, and leave inspired to create a better world.
