A billion year old microfossils

Well preserved ~1 billionw year old Organic microfossils were found at Bitter Springs Formation of Australia. The FIB was used at NASA-JSC Labs. to prepare ultra-thin cross sections and then HRTEM and STXM/XANES analyses were performed.Together these analyses of FIBed organic microfossils from Early Earth materials open up a new line of research where we can more specifically characterize remnants of early life.  Data from these studies would provide insight into recognizing fragmentary organic remains from living systems from either the early Earth or extraterrestrial bodies. In the picture, the cross section of filamentous microfossils are visible.

Bacteria (one of them is a bacterium) are very small organisms. They are prokaryotic microorganisms. Bacterial cells do not have a nucleus, and most have no organelles with membranes round them. However, they do have DNA, and their biochemistry is basically the same as other living things.

ESEM - Calcium sulfphate dihydrate.

The hydration of calcium sulphate hemihydrate (CaSO4.0,5H2O) leads to gypsum (calcium sulphate dihydrate – CaSO4.2H2O). It is a highly exothermic reaction which occurs by a dissolution/reprecipitation mechanism: when the hemihydrate is mixed with water, a fraction of it dissolves to give a saturated solution with respect to Ca2+ and SO4 2- ions, which is supersaturated with respect to calcium sulfphate dihydrate leading to nucleation and crystal growth. ESEM images taken from the hemihydrate hydration process. One can follow water adsorption to the hemihydrate at a 100% RH and the resulting needle-like crystals which result after water elimination.
