Although the ID NOW platform is less sensitive than RT–PCR for identification of SARS-CoV-2 infection, it provides high positive and negative predictive values in low-prevalence populations.

A simple model provides an accessible framework to infer macroscopic parameters of effective resource competition from longitudinal studies of microbial communities.

The conformational cycle of an ABC heterodimeric transporter reveals a divergence in the structural mechanism of ABC exporters.

Electron crystallography and molecular dynamics simulations show that a cholesterol sandwiched in between two neighboring aquaporin-0 tetramers stabilizes the association between the tetramers and thus promotes array formation.

Physical association between sister replisomes early in the E. coli replication phase promotes rapid fork progression and inhibits fork stalling.

Comprehensive, high-resolution lineage mapping of the fly brain reveals straightforward rules that drive neuronal complexity and probable evidence of brain evolution.

Analysis of bearded dragon model reveals a novel tooth replacement strategy that demonstrates the critical importance of epithelial patterning, cell migration, and putative stem cell functional specialization in tissue regeneration.

Thymic macrophages are unique phagocytes with antigen-presenting abilities that comprise a Timd4⁺ subset of embryonic origin located in the cortex and a Cx3cr1⁺ subset derived from adult hematopoietic stem cells residing in the medulla.

The intermediate state conformation of the human KCNQ1 potassium channel voltage sensor domain was determined, validated, and shown to be conductive under physiological conditions.

Genetic variants introgressed into modern humans from Neanderthals tend to be depleted in their contribution to heritable trait variation relative to modern human variants consistent with the action of purifying selection.
