History of Marsâ habitability preserved in ancient dunes
On Earth, scientists study rock layers and the fossils embedded in them to learn about ancient life. A new study focused on red Mars – the desert planet – did something similar. It looked at the record of changing habitability preserved in ancient dune fields.
Archaeologists pinpoint population for the Greater Angkor region
(University of Oregon) Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia’s Greater Angkor region was home to 700,000-900,000 people. The new estimate, made possible by a study designed at the University of Oregon, is the first for the entire 3,000-square-kilometer low-density region.

Red Sea is no longer a baby ocean
(Helmholtz Centre for Ocean Research Kiel (GEOMAR)) The Red Sea is a fascinating and still puzzling area of investigation for geoscientists. Controversial questions include its age and whether it represents a special case in ocean basin formation or if it has evolved similarly to other, larger ocean basins. Researchers from Germany, Saudi Arabia and Iceland have now published a new tectonic model that suggests that the Red Sea is not only a typical ocean, but more mature than thought before.
