That's a wrap on day two of World Science Festival Brisbane, and our suspicions have been confirmed – cats are taking over the internet!

The possibilities of 3D printing in the world of medicine are making revolutionary shifts in the way we treat serious conditions and the second of the "Water Talks" series highlighted the links between agricultural water efficiencies and the sustainability of our planet.

After a full day it seems certain - the incredible contributors, scientists, and volunteers at the festival are taking leaps and bounds for Brisbane on its journey to becoming the new "city of science"!

Tune in tomorrow morning for day three, which kicks off with scientists attempt to find out whether Douglas Adams was right - is the answer to the life, universe and everything really 42?
