Dusty treasure trove reveals forest destruction

The two-toed sloth, a nocturnal mammal found in the Amazon.

Did you know?

Einstein once explained the very complex theory of relativity, E=mc², in this very simple way - "When a man sits with a pretty girl for an hour, it feels like a minute. But let him sit on a hot stove for a minute and it's longer than any hour."

Lizard of Oz


	Take a journey back into a past of dinosaurs and extinction before getting a glimpse at some of our possible futures from the views of Australia's top scientists, in this edition of Velocity. The impact that humans have had on planet earth are continually being revealed. Discover how we have contributed to the extinction of some of the megafauna that once ruled the food chain; learn about the ancient mangrove forests that are entombed beneath the Great Barrier Reef; and take a look at exotic dinosaur fossils all the way from China. Then peer into the future as scientists ponder a world without physics; attempt to ensure the continued existence of endangered rhinos; and develop new tools for testing climate change.

Dusty treasure trove reveals forest destruction


	Two Australian scientists have discovered a new tool for testing global warming and deforestation using rainfall information collected over 40 years from sites in the Amazon jungle and the Andes mountain range. Professor Ann Henderson-Sellers, Director of Environment at ANSTO, said the treasure trove of data comes from a network originally established to monitor radioactive fallout from nuclear bomb testing in the 1950s and 1960s.

Blitzing the biosphere


	Two ecologists from the top end say we humans have to watch our step, or more animals and plants will end up as dead as a Diprotodon.

Dilemma for a horny beast


	While rhinos have been hunted to near extinction for their allegedly aphrodisiac horns, the beasts sometimes have difficulty with their own sex lives.

What has physics ever done for me?


	If it weren't for physics, you wouldn't be reading this because the World Wide Web, computers and electricity all started out as physics projects.

Country by Tim Flannery


	Scientist and author Tim Flannery, one of Australian science's great provocateurs, explores his theories on the development of this country's fauna, in particular the kangaroo, in a lyrical (and exclusive) excerpt from his latest book, Country (Text Publishing)…

Barrier Reef mangroves reveal their secrets


	North Queensland scientists have opened a window into the past by exposing ancient mangrove forests entombed beneath the Great Barrier Reef.


	The vast knowledge of Chinese dinosaurs that Museum Victoria's Head of Science, Dr John Long, possesses has proven useful in Melbourne Museum's latest blockbuster exhibition, Dinosaurs from China.
