Many thanks to the editors of Science for being repeat customers of my images!
And, for the photographers out there who want to know how I did this, the answer is sadly low-tech: I posted a keyword-rich album of mouse closeups many years ago on my Photoshelter website, and the art associates / designers of Science found me. They e-mailed me with an urgent request, and both times we had a contract and price agreed on within a few hours of their first e-mail.
