Somatic stem and niche cells in the Drosophila ovary develop from common precursors through regulated proliferative expansion, followed by acquisition of position-specific behaviors, rather than through rigid early specification events.
Data exploring host and parasite signatures in the peripheral blood indicate that total parasite biomass is a better predictor of P. vivax-induced host responses and pathogenesis than peripheral parasitemia.
Retinal pigment epithelium flattening is an efficient solution adopted by the fast-developing zebrafish to enable folding of the eye primordia, which contrasts with the proliferation-based mechanism used by amniotes.
A parsimonious biophysical model correctly predicts the conserved expression stoichiometry of core bacterial mRNA translation factors, providing intuitive and quantitative design principles for in vivo pathway construction.
The current findings address the redox regulation of hypoxia inducible factor 1α (HIF1α) stability in hypoxia by showing that cytosolic, mitochondrial or lipid ROS are not necessary for HIF1α stabilization in hypoxia.
Lineage tracing and genetic experiments resolve a long-standing controversy by showing that retinoic acid signaling is active in cardiomyocytes, both during development and after myocardial infarction, and protects damaged hearts from apoptosis.
Estimating fine-scale spatiotemporal patterns of Plasmodium falciparum transmission showed an association between entomological inoculation rate and parasite prevalence that emphasizes the value of both measures in malaria surveillance.
Lesions to the anterior-medio-dorsal thalamus cause widespread behavioral impairments across multiple cognitive domains, suggesting that thalamic hubs are critical for interconnecting diverse cognitive processes.
