Here, to start the new year in a thoughtful mood, are a few ehtical questions regarding nanotechnology from Mike Treder at the Responsible Nanotechnology blog. Let us enter the new year hopeful, careful and caring, and leave it with good news, abundance, and a clearer vision for the future.

- What are the acceptable limits of nanotechnology use that can be imposed to prevent dangerous concentrations of power in nations, groups, or persons?

- How much can individual freedom be curtailed before the solution becomes worse than the problem?

- How can any group or organization be given power to globally regulate the use of nanotechnology without also giving that group the power to dominate the world?

- What efforts should be made, if any, to assure that the opportunity for unprecedented abundance is made available to all?

- If nanotechnology and bioengineering enable extreme augmentation of humans, at what point do transformed individuals cease being human?
