Nearly 500 ceremonial sites were uncovered using lidar and have been mapped across the study site. Source: Inomata et al.Scientists have uncovered nearly 500 smaller ceremonial complexes that are similar in shape and features to Aguada Fénix, the largest and oldest Maya monument. The find transforms previous understanding of Mesoamerican civilization origins and the relationship between the Olmec and the Maya people

The satellite image shows the morphologies of fossil rivers in southern Egypt. This study shows that these rivers were intensely active during the African wet period.

Scientists found that following a rapid temperature increase of about 7°C, the frequency of heavy rainfall events increased fourfold, increasing river flooding and forcing riverine populations to migrate to the center of the country
