Lawrence LeBlond for redOrbit.com - Your Universe Online A 2010 controversial study that discovered a certain bacterium that used arsenic instead of phosphorus to build its DNA had been heavily scrutinized by the scientific community. Other researchers, awestruck by such a revelation, set out to replicate the study, yet were unable to glean the same results. Now, after intense studies over the past two years, researchers from Israel, France and Switzerland have found that the bacterium...
New method for measuring slow life in the seabed can provide knowledge about the global carbon cycle "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. Bacteria are the only living organisms to produce D-amino acids that deposit a chemical signature in the mud in which they...

Dolomite is a mineral (formula CaMg(CO3)2) consisting of a calcium magnesium carbonate found in crystals and in beds as dolostone. 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,...
