A long-undeciphered script receives renewed attention and a contested interpretation.

PURPOSE: Neurocysticercosis (NCC) is a common cause of epilepsy in low- and middle-income countries (LMICs). Few studies have described neuroimaging findings in individuals with headaches in addition to epilepsy. Our aim was therefore to describe the types of NCC lesions seen on cerebral computed tomography (cCT), among participants with progressively worsening severe headaches (PWSH) and epilepsy living in 60 villages in Burkina Faso, and to determine the prevalence of NCC in these groups,.

CONCLUSIONS: This iAmHealthy multi-state feasibility RCT demonstrated high retention and successful blinding of assessors. Although the study was not powered to detect health outcome differences, iAmHealthy exhibited a tendency toward greater improvement or attenuated declines in child health outcomes, which supports the conduct of a future fully powered RCT.

Convergence provides strong evidence for adaptation, reflecting similar responses to recurring selection pressures. Waterfowl (order Anseriformes) have repeatedly evolved morphotypes putatively correlated with foraging ecology (e.g., dabbler, grazer, diver), making them an ideal model for testing hypotheses of adaptive evolution. Here, we estimated the most robust time-calibrated phylogenetic tree for the waterfowl to date and quantified the shape of the skull, femur, tibiotarsus, and...
