We've all seen "images" of the coronavirus, but how do we know what a virus actually looks like? Brady Johnston uses complex scientific arts and crafts to visualise stuff that's too small for us to see. He joined the Particle Podcast to talk about long nights in the lab, art vs. science and what it's like to work with DNA.   You can find Brady on twitter @bradyajohnston or on his website https://bradyajohnston.github.io (https://bradyajohnston.github.io/) He's also got a Youtube channel youtube.com/c/bradyjohnston (http://youtube.com/c/bradyjohnston)   Particle Podcast is about science and the people who just love it. It's produced and presented by Rose Kerr (@rosie.zkerr). You can find more Particle at particle.scitech.org.au (https://particle.scitech.org.au/) or @ParticleWA on Twitter and Instagram.   Particle is powered by Scitech.
