NEWSBREAKERS
Riversleigh #2
A remote sensing survey of the Riversleigh region has revealed extensive areas outside the World Heritage area that give the same signals as the spectacular fossil deposits found within the World Heritage area. Ground truthing by a team from UNSW proved the survey right, finding an extraordinarily different fossil deposit containing some animals not seen before. While the exploration is ongoing it will be at least three months before the new materials have been acid-processed to reveal the treasures they contain. The team also located more than 30 previously unknown caves in the remote region - many more than have been previously found in the World Heritage area.

IN THE NEWS
Passive margin no more?
A new subduction zone may be forming off the coast of Portugal. This suggests a new stage in the motion of the plates that will see the Atlantic Ocean close as continental Europe moves closer to America.

Comet a fizzer?
Comet ISON, originally predicted to be the comet of the century, does not seem to be living up to expectations. While it is moving toward the Sun at 26 kilometres per second it has not brightened since mid-January. It may be that it has exhausted its supply of ice or it might be covered in vapour suppressing silicate dust but whatever the reason it seems unlikely it get anywhere near as bright as predicted.

Earthquake flatulence
Methane escaping from warming permafrost and adding to the greenhouse gas load in the atmosphere has been a cause for concern for sometime. Now it seems earthquakes can play a role in liberating vast volumes of methane from deep ocean marine sediments where it might otherwise remain trapped as icy methane hydrate.

Short fuse
A new study of Costa Rica's largest stratovolcano suggests magma rapidly rising from the mantle triggered its 1960's eruptions. It is hoped this work might lead to better tools for predicting eruptions.

IN THE MEDIA
Canowindra given a boost
Sir David Attenborough took a break from his two-week speaking tour to visit the world class Canowindra fossil fish deposit in rural NSW. As one of the country's most important fossil deposits it was a logical location to visit, especially when such an important local museum is apparently being side-lined by the Australian Museum. Perhaps the museum should take note of Sir David's comments.

Steam'n
Yellowstone's unpredictable Steamboat Geyser erupted for the first time in eight years recently, launching steam and water 60 to 90 metres into the air. Thirty to forty visitors on a nearby boardwalk were drenched but unharmed.

Mars: the field trip - One year on!

Discovery 1: The right stuff for life.
Rock analysis has revealed the chemistry of Mars could support life as we know it.
Discovery 2: Unequivocal sedimentary rocks.
Layered sedimentary rocks, pebbly conglomerate and laminated siltstone all point to an ancient environment with running water and fluvial depositional environments.
Discovery 3: Hazardous radiation outbound from Earth.
The journey from Earth to Mars enabled radiation levels to be monitored in a situation not unlike the one that will be encountered by the first humans travelling to Mars. The results suggest dangerous exposure levels will need to be addressed through careful design of the living quarters and other environmental systems.
Discovery 4: No methane detected.
Traces of methane would suggest life as we know it might be present. Mars shows no signs of methane and, it could be inferred, no signs of life but the search will continue.
Discovery 5: Unexpected geodiversity!
The diversity of rocks and soils found to date has been something of a surprise. Sedimentary rocks, igneous rocks, aeolian sediments and soils as well as a suite of vein filling minerals. On the journey to Mt Sharp there is certain to more!
