The Potential Origins Of Life In Ancient Hot Springs

by Keith CowingJanuary 14, 2024January 16, 2024

Newcastle University research turns to ancient hot springs to explore the origins of life on Earth. The research team, funded by the UK’s Natural Environmental Research Council, investigated how the […]

a Surface elevation of the Antarctic Ice Sheet from the Reference Elevation Model of Antarctica68. The black line marks the present-day grounding line74; pale areas are floating ice shelves. b Bed elevation of Antarctica beneath the grounded ice sheet from BedMachine v.364. Surface and bed elevations are relative to the global mean sea level (the EIGEN-6C4 geoid). The black dashed box shows the extent of the maps in Figs. 2 and 5, and lines of latitude are separated by 5°. ASB Aurora Subglacial Basin, DML Dronning Maud Land, GSM Gamburtsev Subglacial Mountains, TAM Transantarctic Mountains, WSB Wilkes Subglacial Basin. c Composite global oxygen isotope record from benthic foraminifera75. Lower (more negative) δ18O values indicate lower ice volume and/or warmer ocean temperatures; higher (more positive) δ18O values indicate greater ice volume and/or cooler ocean temperatures. Labels show the timings of major climate intervals or transitions (red), glacial expansions (black), and prevailing glacial conditions (blue). Plio. = Pliocene; Plt. = Pleistocene; note that the Holocene epoch (0.012–0 Ma) is not shown on the timescale. -- Science

Ancient Landscape Discovered Beneath The East Antarctic Ice Sheet

by Keith CowingNovember 11, 2023November 11, 2023

Editor’s note: of particular interest to Astrobiology mission planners are the ice-covered worlds in our solar system – Enceladus, Europa, Ganymede, Mimas, Titan, etc. and the probability that they have […]

Ancient Source Of Oxygen For Life Hidden Deep In The Earth's Crust

by Keith CowingAugust 9, 2022

Scientists at Newcastle University have uncovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis. The pioneering research project, led by Newcastle […]
