TL;DR: Dating by radiocarbon, luminescence, uranium-series and electron spin resonance methods indicates that H. floresiensis existed from before 38,000 years ago (kyr) until at least 18 kyr, and originated from an early dispersal of Homo erectus that reached Flores and then survived on this island refuge until relatively recently.

TL;DR: In this article, the authors presented a precisely dated reconstruction of monsoon rainfall over the past 12,000 years, based on oxygen isotope measurements from two stalagmites collected in southeast Indonesia.

TL;DR: Geochemical and Nd isotopic studies are reported for widespread Late Proterozoic (approximately 800 Ma) mafic dyke swarms and volcanics in central-southern Australia as discussed by the authors.

TL;DR: In this article, the authors report the enrichment and characterisation of a novel archaeon in a laboratory-scale bioreactor fed with Fe(III) oxide (ferrihydrite) and methane.

TL;DR: In this paper, a study of rare earth element geochemistry in ancient rocks requires the preservation of their distribution patterns through subsequent diagenesis, and the subject of this study, Pleistocene scleractinian coral skeletons from Windley Key, Florida, have undergone partial to complete neomorphism from aragonite to calcite in a meteoric setting; they allow direct comparison of rare Earth element distributions in original coral skeleton and in neomorphic calcite.
