Pulse generation is an emergent property of the arcuate kisspeptin network that is regulated throughout the ovarian cycle via coordinated changes in neuronal communication and basal activation.

Lactate is preferred to glucose as an energy substrate and exacerbates spiking activity in most neuron types of juvenile somatosensory cortex by closing ATP-sensitive potassium channels.
A large repertoire of nanobodies that target discrete regions of SARS-CoV-2 spike shows effective neutralization against variants of concern with many pairwise combinations resistant to escape and demonstrating synergistic neutralization activities.

A project to repeat experiments from high-impact papers in cancer biology found that the effects observed in replications were frequently weaker than, or inconsistent with, the effects reported in the original papers.

Bacterial gut pathogens that invade into host tissues during infection can boost the spread and accumulation of plasmids over time by forming reservoirs containing these plasmids within host tissues.
Genetic and imaging analysis reveal that microglial precursors use ocular blood vessels as a pathway to enter the optic cup and subsequently infiltrate the retina preferentially through the neurogenic region.

A project to repeat experiments from high-impact papers in cancer biology did not complete all replications, with challenges ranging from mundane reasons to unexpected methodological issues.

Regulation of a nuclear receptor signaling pathway may cure the often-lethal disease caused by the endemic parasitic roundworm, Strongyloides stercoralis.
