A lidar mapping study shows ancient residents of Teotihuacan moved astonishing quantities of soil and bedrock for construction and reshaped the landscape in a way that continues to influence the contours of modern activities in this part of Mexico. The paper also shows how Teotihuacan’s engineers re-routed two rivers to align with points of astronomical significance, identified hundreds of previously unknown architectural features, and documented over 200 archaeological features that have been destroyed by mining and urbanization since the 1960s.

Although August’s nTIDE COVID Update graphic shows lower unemployment, it is important to keep in mind that declines in unemployment may reflect movement ‘in to’ or ‘out of’ the labor market,” noted expert Andrew Houtenville, PhD, “Unemployment declines when people get jobs or are recalled to work, for example, but also when they stop looking for work and drop out of the labor market. For August, we also saw increases in the employment-to-population ratio and the labor participation rate for people with disabilities. That’s indicative of a net increase in employment for this population, which is the more likely scenario for the drop in unemployment.”

Chemical engineers at the University of Illinois Urbana-Champaign now understand how water molecules assemble and change shape in some settings, revealing a new strategy to speed up chemical reactions critical to industry and environmental sustainability. The new approach is poised to play a role in helping chemical manufacturers move away from harmful solvent catalysts in favor of water.
