Fabrics Tested Block Virus-Like Particles
U.S. Researchers tested 70 fabrics for their ability to block virus-like particles and reduce viral-aerosol inhalation. Several made the cut

Implications for which fabrics, and how many layers of each, to reach for when making home-made face masks with more than 95% filtration efficiency.
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
Image of Novel SARS-CoV-2 coronavirus, magnified 30,000 to 90,000 times their actual size, emerging from the surface of cells (gray) cultured in the lab, after duplication.
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.
