By the article I wasn't very impressed. To me it seemed that some journalist didn't understand what color coding was. But actually, they are right, it definitely is a new method other than microscopy. I only got aware of that once I read the paper.<p>Basically, what they are doing is to spread so-called UMI (think of it as UUID) markers onto the material. Then they obtain pairwise distance information between an UMI and its neighbours and encode it into a DNA strand. Last but not least, that DNA strand is being sequenced and the pairwise distance information read out. A computation step creates the final image from the distance information.
