The magazine Science published the results of the 2012 Science and Engineering Visualization Challenge, and among the images mentioned was the one below of plant seeds. The images were made by combining high-resolution high-contrast X-ray radiography of plant seeds with images taken by microscopy and the application of these non-destructive micro-imaging techniques is relatively new to botany. The investigative value of this imaging on seeds isn’t quite obvious to me, but I very much enjoy looking at them for their own sake.

They remind me a bit of the snake drawings from The Little Prince and the mysteries of what we can and can’t see with the naked eye.
