New results: Substrate controls first terrestrial microbes to colonise meteorites!

New results from our lab show that the geochemistry and physical properties of a sterile rock control which microorganisms are able to colonise that rock. In a study led by Alastair Tait, we show that the structure of the microbial community in stony meteorites collected from Australia’s Nullarbor Plain is controlled by the substrate and will not reach homeostasis with the community in Nullarbor soils, even after ~35,000 years. This work shows that meteorites, which are sterile when they fall to Earth and other planets, can be used to test ideas relating to first colonisers.

New results on metal mobility during carbon mineralisation!

 

Check out our recent results on metal mobility during carbon mineralisation! This study was led by Jess Hamilton. It shows that potentially hazardous first row transition metals are immobilised within the crystal structures of carbonate minerals, and adsorbed to Fe-oxyhydroxides, under conditions relevant to carbon mineralisation in ultramafic landscapes and industrial reactors.

EGEL members at the DXC

Catch Connor Turvey and Jessica Hamilton at the Denver X-ray Conference in a few weeks. Jessica won an all-expenses paid trip to DXC for having the top poster at this year’s Australian X-ray Analyatical Association Conference. Connor won a DXC Robert L. Snyder Student Award to support his travel to give an invited talk. Nice job everyone!

The EGEL is bound for Goldschmidt2017

Catch EGEL members at Goldschmidt2017! Two of our number, Jessica Hamilton and Connor Turvey, have been granted Global Environmental Sustainability Awards from the Balwyn Rotary Club (balwynrotary.org.au) to support their travel to Paris. Well done!
