I guessing that these images are artificially coloured, given "nanometer-scale auto fluorescence microscopy" as one of the methods. Quite amazing none the less.

Yup, the original paper (https://www.nature.com/articles/s41598-018-31890-9.pdf https://www.nature.com/articles/s41598-018-31890-9.pdf) seems to suggest this: “SRAF image composed of merged three pseudo-colored red, green and blue (RGB) channels. Brightness and contrast of the RGB channel intensities are adjusted to highlight the dark crystalline fabrics.“

Well technically less amazing or you wouldn't have brought it up. If it were equally amazing you wouldn't care and if it were truly more amazing you'd be left wondering how. Ultimately you really feel like this is just up to par. Except for the chance to signal that you "get" wavelengths. Edit: oh man no way, thejacenxpress seems to have blown this guy clean out of the water. If all his greater-than sign quotes are to be believed and to be believed that they came from the linked material... the parent's post shines through as being truly fraudulent in a way I only lightly touched upon. Downvote and ban he! I like how somewhere else in the thread someone is wondering "how can the New York times be trash?" Who on Earth would question their non-failing nature? Meta-edit: I seem to have turned this into an opportunity to bash NYT. Seems self-awareness isn't lost on me after all.
