Summary Scoping deep space from balloons; designing sky scrapers for quake zones; recycling e-waste; and why are things darker when wet?SPACE BALLOONSTo search deep space, astronomers don't just rely on observatories and space telescopes. They also use balloons. In Alice Springs, an international crew of astrophysicists and engineers are set to launch a balloon the size of a football field that will go up to the outer limits of the stratosphere. X-ray and Gamma-ray telescopes on board will study the rays coming from black holes, the centre of the galaxy, and from antimatter. But, as Graham Phillips finds out, launching a balloon laden with expensive equipment is not easy. JAPAN EARTHQUAKEJapan is one of the most earthquake prone regions in the world. So its modern buildings and infrastructure are designed to resist collapse. But, as Maryanne Demasi discovers, an ancient pagoda design seems to be resistant to major earth tremors too. The design principles of the pagoda have been studied and tested and have inspired the architecture of the Tokyo Sky Tree, a free standing communications tower more than 600metres high. PHYSICS OF RECYCLINGOur consumerist lifestyle is leading to a growing mountain of waste. Recycling as much of that as possible is of course essential. But the challenge is finding cost effective ways of doing it. Tanya Ha investigates the latest technology being used to salvage treasure from trash. FUNDAMENTALS WITH BERNIE HOBBS - DARKER WHEN WETAll great discoveries in science begin with somebody asking a question. Newton asked "why do things fall to the ground?" Darwin asked "How did we end up as we are?" And Bernie Hobbs isn't afraid to ask the big questions either... like, why are things darker when they're wet?
