The Virus Up Close: How Scientists Visualize Microscopic Enemies.

Visual artist Austin Athman colorizes a SARS-CoV-2 image at NIH-NIAID’s Rocky Mountain Lab.

You might have seen beautifully colored images of magnified viruses and bacteria in news stories and on the covers of scientific journals – particularly the SARS-CoV-2 images (the virus that causes COVID-19) appearing everywhere. While the
