| Open AccessA NPAS4–NuA4 complex couples synaptic activity to DNA repair
A neuron-specific activity-dependent DNA repair mechanism is identified, the impairment of which may lead to neurodevelopmental disorders, neurodegeneration and ageing.

CCR5 closes the temporal window for memory linking
A molecular mechanism involving CCR5 and CCL5 determines the temporal window in which a memory can be linked with subsequent memories, and in aged mice an increase in CCR5 is associated with defects in memory linking.

| Open AccessBrain charts for the human lifespan
MRI data from more than 100 studies have been aggregated to yield new insights about brain development and ageing, and create an interactive open resource for comparison of brain structures throughout the human lifespan, including those associated with neurological and psychiatric disorders.

Two conserved epigenetic regulators prevent healthy ageing
Two epigenetic regulators—identified in an RNA interference screen in Caenhorhabditis elegans, and conserved in mammals—diminish mitochondrial function and accelerate the age-related deterioration of behaviour.

Functional aspects of meningeal lymphatics in ageing and Alzheimer’s disease
Meningeal lymphatic dysfunction promotes amyloid-β deposition in the meninges and worsens brain amyloid-β pathology, acting as an aggravating factor in Alzheimer’s disease and in age-associated cognitive decline; improving meningeal lymphatic function could help to prevent or delay age-associated neurological diseases.

Genetic variation in glia–neuron signalling modulates ageing rate
Identifying the gene polymorphisms that are the foundations of variation in glia–neuron signalling in Caenorhabditis elegans provides insight into highly variable age-related declines in worm behaviours.

REST and stress resistance in ageing and Alzheimer’s disease
REST, a developmental regulator, is markedly induced in human neurons during ageing but is lost in Alzheimer’s disease; REST represses genes that promote neurodegeneration, is neuroprotective in animal models, and is associated with cognitive preservation and longevity in humans.
