  • Strange alien slime discovered living beneath the Nullarbor Plain
    thrive in the Weebubbie caves Earlier studies on the community suggested that there was an unusual chemistry going on in the caves but we didn t know how the microbes were making a living in the cave environment says the lead scientist Professor Ian Paulsen Macquarie University In order to find this missing link the team of researchers made use of a range of new technologies such next generation sequencing of environmental DNA and scanning electron microscopy to take an in depth look at the composition of the Weebubbie cave slime community This approach detected a dominant group of organisms in the cave slimes known as the Thaumarchaeota This community of microbes thrives in the total dark independent of photosynthesis It is thought that the periodic inundations of the Nullarbor caves by the sea occurred a number of times in the geological past and so researchers suggest that the Weebubbie Thaumarchaeota may have a marine origin We know that the Nullarbor Plain s karst system arose from the sea in the Middle Miocene period and so this may be a clue as to where the Weebubbie Thaumarchaeota came from says Professor Paulsen The research team says this analysis shows that
