This educational short narrated by NPR’s science correspondent Robert Krulwich and medical animator David Bolinsky, shows us how the flu virus gets access to our system (it has a key, LOL) and tricks our own cells into becoming the assembly-line factories that churn out more and more copies of the virus itself.
Bolinsky who created the video says that it is essentially in slow motion, the infection process takes a fraction of a second to occur. Also, they added colour to the different protein and DNA material in the video because at their tiny size they are, for all intents and purposes, colourless.
