    Two-photon calcium imaging of the medial prefrontal cortex and hippocampus without cortical invasion

    Masashi Kondo et al.
    Establishment of two-photon imaging with a 1100-nm laser, which underfills the objective's back aperture, detects activity of multiple neurons in the prelimbic area and hippocampal CA1 region of the intact mouse brain.

    Live calcium and mitochondrial imaging in the enteric nervous system of Parkinson patients and controls

    An-Sofie Desmet et al.
    In contrast to previous post-mortem or fixed tissue histochemical reports, live calcium and mitochondrial imaging data suggest that the enteric nervous system is not generally affected in Parkinson's disease patients.

    Protein biogenesis machinery is a driver of replicative aging in yeast

    Georges E Janssens et al.
    A comprehensive mapping of the proteome and transcriptome during the complete replicative lifespan of budding yeast predicted an increased abundance of the protein biogenesis machinery is most causal for aging.

    SIR-2.1 integrates metabolic homeostasis with the reproductive neuromuscular excitability in early aging male Caenorhabditis elegans

    Xiaoyan Guo, L René García
    A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.

    Age- and diet-associated metabolome remodeling characterizes the aging process driven by damage accumulation

    Andrei S Avanesov et al.
    Aging is a process characterized by gradual metabolome remodeling, deceleration of the remodeling in late life and under conditions that extend lifespan, and a mortality-associated pattern of cumulative damage.

    Dopaminergic modulation of the exploration/exploitation trade-off in human decision-making

    Karima Chakroun et al.
    Dopamine attenuates exploration during decision-making via a reduction of neural tracking of uncertainty.

    Long-term live imaging of the Drosophila adult midgut reveals real-time dynamics of division, differentiation and loss

    Judy Lisette Martin et al.
    A new platform for imaging live Drosophila adults yields vivid movies of the midgut over prolonged time scales, opening the door to the real-time study of organ renewal dynamics in a near-native context.

    Epigenetic drift of H3K27me3 in aging links glycolysis to healthy longevity in Drosophila

    Zaijun Ma et al.
    Epigenetic drift of H3K27me3 is one of the molecular mechanisms that contribute to aging, and stimulation of glycolysis promotes metabolic health and longevity.

    celsr1a is essential for tissue homeostasis and onset of aging phenotypes in the zebrafish

    Chunmei Li et al.
    The use of forward genetic screens in zebrafish identifies a new model of vertebrate aging, defining the regulating of the onset of aging phenotypes through maintenance of progenitor cell populations.

    Imaging of glucose metabolism by 13C-MRI distinguishes pancreatic cancer subtypes in mice

    Shun Kishimoto et al.
    Using noise suppression, real-time imaging of glucose metabolism is possible by 13C MRI and reveals previously undetected metabolic differences within tumors.
