Penetration of the fluoroquinolones in tuberculosis lesions is heterogeneous even in fully cellular areas, is driven by macrophage content and decreases as the distance from lesion outer rim increases.

Many developmental functions in marsupials and eutherian mammals are accomplished by different tissues, but similar genes.

Rabbits can learn the biological analogue of a simple recursive function by relying only on the neurons of the cerebellum.

Fast-spiking interneurons of the dorsolateral striatum are found to provide a microcircuit mechanism driving the circuit properties and behavioral adaptations that characterize habit.

All parts of the USA are similarly adapted to temperature seasonality, although mortality seasonality, and how it has changed since the 1980s, depend on age and sex.

A dimensional approach to psychiatry demonstrates the specificity and generalizability of a neurocognitive marker of compulsive behavior and intrusive thought via large-scale online testing.

Structures of the signal recognition particle before and after it captures a transmembrane domain suggest how it chooses, engages, and shields its clients during membrane protein targeting to the endoplasmic reticulum.

Zona pellucida requires ZP4 protein to efficiently protect the developing embryo during in vivo pre-implantation development.

Dorsomedial and dorsolateral striatal neural activity differ during early learning of action sequences but do not change with performance improvement across sessions, and become similar after extended training.

Transporters shared by fungal intracellular parasites provide new insights into the evolution of nucleotide and energy parasitism.
