Oldest evidence of life discovered in Australia
Researchers have discovered rare, living specimens of stromatolites, the oldest evidence of life on Earth,  deep within a remote and protected World Heritage Area in Australia.

The discovery was made by a group of researchers including those from the University of Tasmania in Australia. They made the discovery while surveying peat- bound karstic wetlands, an unusual type of swamp, which occurs only in peaty soils underlain by limestone and similar carbonate rocks.

The stromatolites were previously unknown. According to Bernadette Proemse, a researcher from Tasmania University, “The ecosystem has developed around spring mounds where mineral-rich groundwater is forced to the surface by geological structures in underlying limestone rocks.”

Cabinet approves the establishment of the National Anti-profiteering Authority under GST
The Union Cabinet led by the Prime Minister Narendra Modi has given its consent for the creation of the posts of Chairman and Technical Members of the National Anti-profiteering Authority (NAA) under GST.
