Canadian scientists have discovered how chemical structure can elicit a quantum state that permits the ultrafast movement of energy along an organic polymer. This discovery should facilitate a number of nanotech applications, including inexpensive solar cells…
Following up on recent posts about concern in the insurance industry and in Congress about risk management practices for (current and near-term) nanotechnology, David Forrest passes along this news of recent action at EPA…
We noted a few weeks ago a new nanotech method to make structurally pure metallic single-walled carbon nanotubes (SWNTs) and, the following week, a way to prepare semiconducting SWNTs from mixtures by eliminating the metallic ones. Maintaining the momentum of rapid progress, now comes a method to prepare high-density arrays of perfectly aligned, 95%-pure semiconducting SWNTs…
In new variation of ways to use nanotech to treat cancer, scientists have shown that using a scorpion toxin to target nanoparticles to brain cancer cells depletes the amount on the cancer cell surface of a protein required to make the cells invasive…

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.
