Out of the logo suggestions so far, I was able to work on the theme proposed by Anoop Nair in his answer, thanks to him making it available for collaboration on GitHub.
This is what I have so far, but I'm open to changing the words used, or adding more equations, or putting more images in the background (I wanted that DNA double-helix to be a protein in tertiary structure, but couldn't find one that was black-and-white):
Please feel free to add suggestions or comments or disagreements in the answers, or to contribute on GitHub! You can change the image here then push to the GitHub repository for the above image to automatically change.
