John de Rivaz, Here's a quote from your article: ** QUOTE ** Scanning electron and atomic force microscopes are now used to capture detail down to a few nanometers. However, such microscopes create images by scanning objects point by point, which means they are typically limited to non-living samples, and image capture times can take up to several minutes. "Optical microscopes can capture an entire frame with a single snapshot in a fraction of a second," said Fang, who is now an assistant professor of mechanical engineering at the University of Illinois at Urbana-Champaign. "That opens up nanoscale imaging to living materials, which can help biologists better understand cell structure and function in real time, and ultimately help in the development of new drugs to treat human diseases." ** UNQOUTE ** It's not a 100-fold improvement in the electron microscope, but it's certainly big progress. I think Richard Feynman would be pleased. Here's a quote of his: ** QUOTE ** We have friends in other fields---in biology, for instance. We physicists often look at them and say, ``You know the reason you fellows are making so little progress?'' (Actually I don't know any field where they are making more rapid progress than they are in biology today.) ``You should use more mathematics, like we do.'' They could answer us---but they're polite, so I'll answer for them: ``What you should do in order for us to make more rapid progress is to make the electron microscope 100 times better.'' ** UNQUOTE ** Plenty of Room at the Bottom Richard P.
