The ZP is a viscoelastic ECM that provides stability for contacts between projections from the innermost cumulus cells and oocyte microvilli that pass through the ZP and form gap junctions shown to be essential for oocyte growth and follicle development.
Organ-selective drug action of traditional Chinese medicine that generates systemic immune mediators is proposed and reviewed as a novel mechanistic angle to develop new immunomodulatory drugs.

A time-gated model is proposed to reconcile the transient vs. persistent biological activities of cellular senescence, in which 'time' seems to be the main orchestrator of the beneficial vs. detrimental effects of the senescent programme.
A circuit between the hippocampus, nucleus reunions, and prefrontal cortex organizes information about the past, present, and future into alternating theta sequences.
The mammalian Y chromosome has become specialised for male fertility, but exact functions of individual Y genes remain poorly understood, a knowledge gap that new approaches can bridge.

Latest advances in biological timing studies substantiate an emerging concept of autonomous clocks that are normally entrained by the cell cycle and/or the circadian clock to run in synchrony, but have evolved to run independently to regulate different cellular events.
An integrated empirical paradigm tracing immune strategies, underlying mechanisms and infection outcomes across reservoir host-pathogen systems, their specific ecological contexts, life-history features, and coevolutionary dynamics can reveal the actual patterns and processes underlying spillover in the wild.
The shared capacity of stem cells to recapitulate initial body plan formation in vitro without species-specific cues, suggests the existence of alternative, evolutionarily conserved developmental trajectories.
