What's the Chemistry of the Fabric Viscose?

A question about the increased aurora boreal of activity around the world at the moment. What's causing that? You're dead right it's increased solar flare activity. And how much are we doing in Australia to create new materials for buildings? We do have some lovely research happening at the Sydney Nano Institute though and there's a fantastic project being run by a chemist and an architect looking at envelopes of buildings.
