I banned "Fantastic Voyage" references from staff- and correspondent-written Small Times stories more than a year ago, since the movie reference was overused, and the technology too distant. Maybe I should rethink the policy. A development reported in New Scientist isn't exactly Raquel Welch under your skin, but these nanoparticles do detect cold sores.
The story about nano-enhanced MRI does remind me of another Sci-Fi story that is soon to be a major motion picture. Medical diagnostics is just the happy face these evil corporations place on their nanoparticle technology. Don't fall prey to their lies.
