    Jagged and Delta-like ligands control distinct events during airway progenitor cell differentiation

    Maria R Stupnikov et al.
    Notch ligands from the Delta and Jagged families have distinct roles in epithelial progenitor cell fate of extrapulmonary and intrapulmonary airways and differentially restrict expansion of the neuroendocrine microenvironment.

    Transient rapamycin treatment can increase lifespan and healthspan in middle-aged mice

    Alessandro Bitto et al.
    Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.
    1. Neuroscience

    Neuropathological and transcriptomic characteristics of the aged brain

    Jeremy A Miller et al.
    High variability in neuropathology burden and interactions between dementia diagnosis and RNA quality present underappreciated complications when studying dementia in an aged population.

    Optogenetic dissection of basolateral amygdala contributions to intertemporal choice in young and aged rats

    Caesar M Hernandez et al.
    Optogenetic approaches in young and aged rats define multiple roles for basolateral amygdala in guiding intertemporal choice, and show that these roles change across the lifespan.

    Hypocretin underlies the evolution of sleep loss in the Mexican cavefish

    James B Jaggard et al.
    The identification of evolutionarily-derived changes in Hypocretin function within the brains of short-sleeping Mexican cavefish provides a system for investigating the mechanistic basis of sleep differences throughout the animal kingdom.

    A complex peripheral code for salt taste in Drosophila

    Alexandria H Jaeger et al.
    Unlike other taste modalities, the Drosophila taste system encodes salt taste combinatorially across multiple sensory neuron classes, which combine to produce behavioural valence and plasticity.

    A new genus of horse from Pleistocene North America

    Peter D Heintzman et al.
    The extinct stilt-legged equids of North America are not related to Asiatic asses or horses, but instead represent a distinct lineage outside of living equid diversity that became extinct in the terminal Pleistocene.

    Selective sorting and destruction of mitochondrial membrane proteins in aged yeast

    Adam L Hughes et al.
    A new mitochondrial protein degradation pathway selectively sorts and destroys a subset of the mitochondrial membrane proteome to protect mitochondria in times of stress.

    Speed and segmentation control mechanisms characterized in rhythmically-active circuits created from spinal neurons produced from genetically-tagged embryonic stem cells

    Matthew J Sternfeld et al.
    Stem cell derived ventral-spinal cord excitatory neurons self-assemble into a rhythmically bursting neural network whose speed and intercellular coordination are both instructively modulated by cell-type specific interactions with inhibitory neurons.

    Ssd1 and Gcn2 suppress global translation efficiency in replicatively aged yeast while their activation extends lifespan

    Zheng Hu et al.
    Activation of the stress response pathway in young cells extends replicative lifespan, not by reducing global protein synthesis per se, but by Gcn4-mediated autophagy induction.
