This week, we seek the science of Architecture. We find out how rapid prototyping technology could help us print out entire houses, and how natural light and ventilation could cut our energy bills. Plus, giggling gorillas tell us how laughter evolved and birds that learn from their neighbours. In Kitchen Science, Dave challenges you to build the best bridge, using only a single sheet of A4 paper!
Jerry asked the Naked Scientists: Dear Naked Scientists, Love Your Show! My wife came up with what I think is the strongest paper bridge yet, a box section with tape sealed ends. This keeps the box section from turning into a parallelogram when a transverse load is put on it. Her second idea was also very strong is to roll each long end into a tube respectively, with a small flat span section between them. My own idea is to have a sealed end box section with a circular inner corrugation, but haven't figured out how to do that with one piece of paper. I need an origami expert to assist!

Mel Holloway asked the Naked Scientists: RE: 7th Jun 2009 - The Science of Architecture - Part of the discussion was the use of light by squid to become "invisible."† In WWII, lights were fixed to the wings of sub chasing bombers to render them invisible to German submarines.
