Airborne Mapping Reveals a Far More Populated pre-Columbian Mesoamerica

Using airborne mapping, researchers are discovering new archeological sites that show pre-Columbian Mesoamerica was “significantly more densely populated at the time of European contact” than previously thought. The findings, which were announced during the 2018 AAAS Annual Meeting in Austin, Texas, have implications for understanding the region’s history of migration, land use and conservation and even early climate changes, participants said.

In Cities, Emissions from Everyday Products Rival Car Emissions

Petroleum-based chemicals in consumer products like soaps and paints drift into the air and contribute as much as car emissions do to air pollution, a new study in the journal Science reports.

Innovation Needs Sustained Government Support, Says Susan Hockfield

A virus genetically engineered to build battery components is one example of how 21st century innovation will be driven by the convergence of scientific disciplines, said AAAS President Susan Hockfield at a 2018 AAAS Annual Meeting press breakfast. These creative solutions are desperately needed, she said, as the global population is expected to reach 9.5 billion people by 2050. From health care to clean water, Hockfield noted, “The way we are currently providing ourselves with all the necessities of life is insufficient to meet the challenges of that size population.”
