Terrorists time their attacks during periods of security or financial crisis, according to new research from political scientists at Binghamton University, State University of New York.

Governments, international bodies and researchers rely on global population data for resource allocation and infrastructure planning to disease epidemiology and disaster risk management. In a new study published in Nature Communications, researchers from Aalto University in Finland show the profound and systematic extent to which these datasets underestimate rural population figures worldwide. 

Researchers from the Universitat Autònoma de Barcelona (UAB) and the Max Planck Institute for Social Anthropology have identified the economic and political borders separating El Argar, considered to be the first state-society in the Iberian Peninsula, from its La Mancha and Valencia Bronze Age neighbours some 4,000 years ago. These communities, with less centralised social structures, maintained complex relations with the Argaric culture. The study, based on an innovative analysis of pottery production and circulation, opens the door to identifying similar border dynamics in other European societies contemporary to El Argar, and understand how the first states were formed in prehistory.
