    Active tactile discrimination is coupled with and modulated by the cardiac cycle

    Alejandro Galvez-Pol, Pavandeep Virdee ... James Kilner
    Human subjects actively adjust the acquisition of sense data based on how their bodily cycles alter their senses, i.e., sensing tactile stimuli for longer periods when concurrent physiological signals are present vs. sensing for shorter periods when these are quiescent.

    Metrics of high cofluctuation and entropy to describe control of cardiac function in the stellate ganglion

    Nil Z Gurel, Koustubh B Sudarshan ... Olujimi A Ajijola
    Networked cardiac control, revealed through analysis of extended baseline-state multi-channel recordings, differentiates heart failure and normal regimes highlighting the promise of peripheral neurally based clinical interventions.

    Human Erbb2-induced Erk activity robustly stimulates cycling and functional remodeling of rat and human cardiomyocytes

    Nicholas Strash, Sophia DeLuca ... Nenad Bursac
    Comparative analysis of cardiac mitogenic pathways identified a potent human gene that is effective at driving in vitro cell cycle activation across species and cell culture systems.

    Developmental alterations in centrosome integrity contribute to the post-mitotic state of mammalian cardiomyocytes

    David C Zebrowski, Silvia Vergarajauregui ... Felix B Engel
    Mammal hearts are unable to replace lost cardiomyocytes, which may be due to the loss of centrosome integrity in these cells after birth.

    Reduced matrix rigidity promotes neonatal cardiomyocyte dedifferentiation, proliferation and clonal expansion

    Yfat Yahalom-Ronen, Dana Rajchman ... Eldad Tzahor
    Compliant matrix provides a permissive micoenvironment for cardiomyocyte dedifferentiation, cell division and expansion, and thus may open a new avenue towards cardiac regeneration.

    The long noncoding RNA Charme supervises cardiomyocyte maturation by controlling cell differentiation programs in the developing heart

    Valeria Taliani, Giulia Buonaiuto ... Monica Ballarino
    The lncRNA pCharme controls the expression of cardiomyocyte maturation genes and heart development by orchestrating the formation of MATR3-enriched nuclear condensates.

    Ingestible pills reveal gastric correlates of emotions

    Giuseppina Porciello, Alessandro Monti ... Salvatore Maria Aglioti
    Direct measures of inner gastrointestinal signals via ingestible capsules highlight the role of stomach pH in shaping human feelings of disgust, fear and happiness.

    Ryanodine receptor 2 inhibition reduces dispersion of cardiac repolarization, improves contractile function, and prevents sudden arrhythmic death in failing hearts

    Pooja Joshi, Shanea Estes ... Swati Dey
    Inhibition of RyR2 hyperactivity with dantrolene not only prevents VT/VF and SCD but also heart failure by mitigating calcium dysfunction in pressure-overloaded hearts.

    Cardiac afferent signals can facilitate visual dominance in binocular rivalry

    John P Veillette, Fan Gao, Howard C Nusbaum
    Sensations arising from internal organs like the heart can affect how the brain decides between two mutually incompatible perceptions of the same visual stimulus.

    Cell-free DNA as a potential biomarker of differentiation and toxicity in cardiac organoids

    Brian Silver, Kevin Gerrish, Erik Tokar
    Cardiac organoids have potential as a tool used for identifying cell-free DNA as biomarkers for toxicity and severity of exposure outcomes.
