| Open AccessImmune microniches shape intestinal Treg function
Studies in mice show that effector T regulatory cells in the gut are most functional in the lamina propria, but this homeostatic niche is disrupted in inflammation, suggesting a spatial mechanism of tolerance to commensal microorganisms.

| Open AccessSpatially organized cellular communities form the developing human heart
Combining single-cell RNA-sequencing with high-resolution multiplexed error-robust fluorescence in situ hybridization reveals in detail the cellular interactions and specialization of cardiac cell types that form and remodel the human heart.

| Open AccessAn atlas of healthy and injured cell states and niches in the human kidney
A high-resolution kidney cellular atlas of 51 main cell types, including rare and previously undescribed cell populations, represents a comprehensive benchmark of cellular states, neighbourhoods, outcome-associated signatures and publicly available interactive visualizations.

| Open AccessLoss of CDK4/6 activity in S/G2 phase leads to cell cycle reversal
We uncover the mechanism underlying the restriction point phenomenon, suggest a role for cyclin-dependent kinase 4 and 6 activity in S and G2 phases, and explain the behaviour of cells following loss of mitogen signalling.

| Open AccessAn atlas of substrate specificities for the human serine/threonine kinome
Analysis of the kinase activity of 300 protein Ser/Thr kinases reveals that the substrate specificity of the kinome is substantially more diverse than expected and is driven extensively by negative selectivity

| Open AccessCells of the human intestinal tract mapped across space and time
Cells from embryonic, fetal, paediatric and adult human intestinal tissue are analysed at different locations along the intestinal tract to construct a single-cell atlas of the developing and adult human intestinal tract, encompassing all cell lineages.

Extensive signal integration by the phytohormone protein network
A systems-level map of the Arabidopsis hormone signalling network, comprising more than 2,000 binary protein–protein interactions, reveals hundreds of interpathway contact points, many of which mediate crosstalk between different hormone pathways.

Non-homeostatic body weight regulation through a brainstem-restricted receptor for GDF15
GDNF receptor alpha-like is a brainstem-restricted receptor for growth and differentiation factor 15, regulating appetite and body weight in non-homeostatic conditions by activating the emergency circuit response to disease and toxin stresses.

Distributed biological computation with multicellular engineered networks
For synthetic biologists' creativity to be unleashed, basic circuits must become truly interchangeable, that is, modular and scalable. This study, one of two linked papers, has harnessed yeast pheromone communication to achieve complex computation through communication between individual cells performing simple logic functions. Such extracellular 'chemical wiring' is one promising way to get around intracellular noise when building more complex genetic circuitry.
