Questions and comments raised by readers at a new blog, Microanalysis:

I heard a rumor that by 2020, nanotechnology will have made such advances that armies of nanobots will perform all of our mundane tasks for us, such as dusting and cleaning up coffee cake crumbs. Is this true?

I was watching public access television last weekend, and a man claiming to be a Ph. D. in futurology said that cancer will be wiped out in a few years because doctors will put nanobots that shoot lasers in our bodies to fight cancer off.

If these questions are any indication, we have a long way to go to educate ourselves about nanotechnology. On the other hand, I suspect the questions may have been cooked up by the blog's author.
