How a Virus Attacks Your Body

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.

Stuxnet: Anatomy of a Computer Virus

In this infographic created for an Australia TV show, writer Scott Mitchell and designer Patrick Clair explains the inner-workings of the Stuxnet, a virus that burrowed its way into large industrial systems in mid-2010.

Unlike the garden-variety viruses, Stuxnet was believed to have been coded by people who had in-depth knowledge of industrial processes and had a range of abilities, one of which allowed it to turn up the pressure inside nuclear reactors. The virus used zero-day exploit, so called because the vulnerability is unknown to software developer.

Have a look at Stuxnet: Anatomy of a Computer Virus below.
