In the latest Science Ink, an immunologist combines two powerful symbols – DNA and the tree – to create a “potent symbol of life.”
“The Tree Seems to be a potent symbol of life in human (at least Western) culture, and what better way to augment this symbol by putting the code for life (DNA) at its base? I got this tattoo to commemorate the beginning of my Ph.D. in immunology,” writes Kevin Bonham.
