White sharks hang with buddies

Apex marine predators choose whom they hang with, researchers reveal. White sharks form communities, researchers have revealed. Although normally solitary predators, white sharks (Carcharodon carcharias) gather in large numbers at certain times of year in order to feast on baby seals.

Perfect fish fossil offers a glimpse into Devonian period

The discovery of a new fish at a famous WA fossil site is in such good condition that it provides an exciting fresh glimpse into the evolution of species from 380 million years ago. The new fish - named Pickeringius acanthophorus (honouring the late Museums Victoria fossil collection manager David Pickering) - lived in the Late Devonian Period. Its beautifully preserved fossil skeleton was discovered by Flinders University’s Professor John Long at the Gogo Formation, in the Kimberleys of Western Australia. This has become a world famous fossil site, containing superb 3-dimensional preservations of entire fishes in limestone nodules, and has so far yielded more than 50 species.

Nothing is at it seems

Who really understands the inner workings of our “modern vibrant” economy - that finely tuned mechanism that gives everyone a fair go and preserves our way of life? Turns out it’s more like one of those classic Bruce Petty cartoons with machines with lots of levers and belching fumes at the hapless operator.

I was recently surprised to happen upon a lecture given by a real life economist who managed to make the swirling mess make sense – and nothing is at it seems. I’ll try to explain- if you are prepared to accept the opinions of someone like me, who you don’t know and will probably never meet – but hey we do that every day when we swallow the opinions of News Corporation and Fairfax media empires, don’t we?
