Hear and see how invisible droplets emit during speech. Researchers used laser technology to light up the spray of otherwise unseen particles that become "aerosolized"during speech. Don't have time? The left video is short, or go to 01:35 in the longer video on the right to see the magnified spray.

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

This scanning electron microscope image shows Novel Coronavirus SARS-CoV-2 (orange)—also known as 2019-nCoV—the virus that causes COVID-19—isolated from a patient in the U.S., emerging from the surface of cells (gray) cultured in the lab.
