Drug-drug cocrystals (DDC) represent a unique subset of pharmaceutical materials offering distinct advantages in combination therapies, pharmacokinetics, and patient compliance. However, their structure-function relationships are rarely reported despite its central importance in successful medicine. A material-sparing approach consisting a molecular and structural perspective is reported to evaluate tabletability of a model DDC, metforminsalicylic acid, to its components metformin HCl (MET) and sodium salicylate (SAL)

The Howiesons Poort (HP) of southern Africa plays an important role in models on the early behavioral evolution of Homo sapiens. The HP is often portrayed as a coherent MSA industry characterized by early complex material culture. Recent work has emphasized parallel technological change through time across southern Africa potentially driven by ecological adaptations or demographic change. Here we examine patterns of diachronic variation within the HP and evaluate potential causal factors behind these changes. We test previous temporal a
