Scientific American Nanotechnology: This site is an excellent resource for breaking scientific news about nano. Scientific American frequently gets eminent scientists to write features.
The National Nanotechnology Initiative: This overview of the federal government program for nanotechnology links to some good education resources. NNI also sponsors occasional lectures and events.
The Nanotechnology Bulletin: This site contains interviews with movers and shakers in nanotechnology. If you want to hear what experts inside the industry are saying, this is a good resource.
The NanoBusiness Alliance: This site is a good source for those interested in the business and political side of nanotechnology. It is also a good place to find out about events and conferences related to nanotechnology.
Nanotech Now: This site is a portal that links to other good sites about nanotechnology.
NanoelectronicsPlanet: This is another good headline and portal site, although it is liable to mix nano with micro and other semirelated news. It also has a nanotech stock portfolio and associated convention.
Why the future doesn't need us: Bill Joy, cofounder of Sun Microsystems and its former Chief Scientist believes that 21st century technology is taking us in a dangerous direction.
An autonomous self-replicating robotic system: Engineers at The Johns Hopkins University have attempted to make a self-replicating robot constructed from LEGO building blocks.
Crystals line up in flash chip : Nanocrystals may soon find their way into flash memory.
Nanotechnology: Drexler and Smalley make the case for and against 'Molecular Assemblers': K. Eric Drexler wrote the book "Engines of Creation" and founded the Foresight Institute. Richard E. Smalley won the 1996 Nobel Prize in Chemistry for the discovery of fullerenes.
Brownian motion: This is a java applet that illustrates the phenomenon of Brownian motion.
The Space Elevator: A space elevator system will provide a safe and inexpensive means of delivering a large mass of payload to earth orbit and to the Moon and Mars, and enable many new types of commercial ventures in space. The Institute for Scientific Research has recently concluded that a space elevator design based on nanotechnology can reach initial operational capability in as little as 15 years, and will require only existing and anticipated near-term technology.
