Ghostly traces of massive ancient river revealed

Using zircon crystals, researchers have discovered the route of a massive ancient river that could help find new reservoirs of fossil fuels and suggest how modern rivers might change over time.

More than two thirds of the worlds’ major cities are located in coastal deltas. How they change over time can impact communities that live around them.

Air, fire, earth and water – understanding our planet in all its moods

In 2011 Australia will hold one of the world’s largest meetings of earth scientists. They will explore all the physical aspects of our planet, from deep in the Earth’s core to our place in space.

Given recent natural disasters—such as the Pakistan floods, Black Saturday bushfires, Hurricane Katrina, the 2004 Boxing Day Tsunami, 2010 Chile earthquake, Iceland’s Eyjafjallajökull volcano—the Earth seems ever more restless and destructive, and the impact on human life and infrastructure is increasingly heavy.

So it is important to understand how the Earth works—which means the 25th General Assembly of the International Union of Geophysics and Geodesy in Melbourne from 28 June to 7 July 2011 will be a focus of attention, not only for the 3,000 delegates expected to attend, but for many others besides.

Ancient zombie ants, liquefying your body, recovering meteorites and more. What Tim’s talking about on radio this week.

This week on radio, Tim Thwaites is talking about tracking and recovering meteorites; liquefying your body; chlorophyll that works with low energy light; ancient zombie ants; and more…

1. Desert fireballs—An intelligent camera system has been set up to track and recover meteorites in the Nullarbor. It is expected to detect about three or four of them a year. Many of these will be recovered. As debris left over from when planets were constructed, they carry a unique record of the birth of the Solar System.—Australasian Science.
