ONLINE COVER Protecting the Placenta from Malaria. Shown is a representative micro-computed tomography image of arterial vasculature in a placenta from a malaria-infected mouse. The colors correspond to vessel diameter, with blue depicting the largest vessels and red the smallest ones. McDonald et al. used this imaging and other data from pregnant mice and human patients with malaria to identify a role for ʟ-arginine in pregnancy outcomes during malaria infection and demonstrate potential benefits of supplementing this amino acid. In a related Focus, Beesonet al. discuss the implications of these findings. [CREDIT: C. MCDONALD, K. KAIN, L. CAHILL, L. GAZDZINSKI, AND J. SLED /UNIVERSITY OF TORONTO]
