""I did my Ph. D on olfaction in sea turtles, sequencing the olfactory receptor genes of the three species featured in my tattoo (leatherback, loggerhead and green). The "bubbles" represent DNA."--Dr. Michelle Vieyra, University of South Carolina. Congratulations, Dr. Vierya--your submission is the 100th addition to my Flickr set of science tattoos. Make full use of your bragging rights. [See also New Scientist's droll blog coverage of this project.]
