Not many of the artists I recommend in this newsletter come with a warning.
David Goodsell is a scientist. He's a "structural biologist." He studies the structures of cells and in particular, viruses. From his studies of these cellular structures, he creates his artwork.
He makes up the colors in his painting because the proteins he's represents have no real color. So he makes up the colors to help distinguish between the different functions each of the proteins have.
I think the representations are fantastic.
The reason I think Goodsell should come with a warning is not that he represents things like HIV, the Zika Virus, and other extremely hazardous cells in his paintings. It's because the subject he's representing makes you want to dig. You can lose yourself for hours in his work.
His artwork makes some very complex functions a little more understandable and accessible.
If you want to find David on the internet, you can find him at Molecular Art | Molecular Science. You'll find out all about him there.
Now go out and make some art!
