Latest Geomicrobiology Stories
A group of British scientists has for the first time found evidence of diverse life forms dating back nearly 100 thousand years in subglacial lake sediment.
A 2010 controversial study that discovered a certain bacterium used arsenic instead of phosphorous to build its DNA had been heavily scrutinized by the scientific community.
"Mud samples boiled in acid sounds like witchcraft," admits microbiologist Bente Lomstein from the Department of Bioscience when explaining how she and an international group of researchers achieved the outstanding results being published today in the journal Nature.

A pure form of dolostone would be rare, however; it usually intergrades with limestone and is referred to as dolomitic limestone, or in old U. S. geologic literature as magnesian limestone. Dolomite has physical properties similar to those of the mineral calcite, but is less soluble in hydrochloric acid. There is uncertainty as to the cause of its formation,...
