Under sustained malaria control in PNG, the incidence of distinct blood-stage infections quantifies heterogeneity in transmission, significantly predicting risk of both P. falciparum and P. vivax malaria episodes at a population and individual scale.
New methods reveal that complex local splicing variations are more prevalent in animals than previously appreciated, and demonstrate that local splicing variations are relevant for studies of development, gene regulation and neurodegenerative diseases.
Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.
The extinct stilt-legged equids of North America are not related to Asiatic asses or horses, but instead represent a distinct lineage outside of living equid diversity that became extinct in the terminal Pleistocene.
Control of neural stem cells by reactive oxygen species (ROS) provides a link between systemic shifts in oxygen tension and neuronal regeneration, and suggests an evolutionary driving force for the inherent ability of newts to regenerate their brain cells.
