For love not money: What keeps circuses on the road? Posted: 31 May 2013 07:52 AM PDT Year-in, year-out the circus comes to town. But in 2013 circuses are in trouble. Seen by many as entertainment from a bygone age and facing Government action to ban circuses with wild animals, what is it that keeps circuses on the road? Why do they carry on going?

The greatest place to be a Martian: Australia? Posted: 31 May 2013 07:52 AM PDT Would Martians feel at home in Australia? Recent research has proven that if Martians took a holiday to Australia they might feel more at home than you'd think. Researchers have recently exposed a unique set of attributes suggesting that the Australian red center could be a close analogue for the surface of the red planet – and how this unusual weathering has led to the formation of Australia's opals.

Building 3-D fractals on a nano scale Posted: 31 May 2013 07:39 AM PDT It starts with one 3-D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating 3D fractal 'building' is formed on the micro and nano scale.

Dairy's carbon footprint: Flatulence tops the list Posted: 31 May 2013 07:17 AM PDT Researchers have conducted a life-cycle analysis of fluid milk that will provide guidance for producers, processors and others throughout the dairy supply chain. The largest contributors were feed production, enteric methane -- gas emitted by the animal itself -- and manure management.
