    Evolutionary loss of foot muscle during development with characteristics of atrophy and no evidence of cell death

    Mai P Tran et al.
    Evolutionary loss of foot muscle in a bipedal rodent shares similarities with skeletal muscle atrophy, which is typically considered a pathological response to injury or disease.

    Single-cell dynamics of pannexin-1-facilitated programmed ATP loss during apoptosis

    Hiromi Imamura et al.
    Cleavage of pannexin-1 channel by caspases facilitates the loss of intracellular ATP level and attenuates glycolytic metabolism of apoptotic cells.

    Cell volume changes contribute to epithelial morphogenesis in zebrafish Kupffer’s vesicle

    Agnik Dasgupta et al.
    During Kupffer's vesicle morphogenesis, cell volume anisotropy impacts cell shape changes.

    Fizzy-Related dictates A cell cycle switch during organ repair and tissue growth responses in the Drosophila hindgut

    Erez Cohen et al.
    Ploidy-increasing endocycles may represent a tradeoff between loss of regenerative capacity and preservation of tissue architecture.

    Impaired respiration elicits SrrAB-dependent programmed cell lysis and biofilm formation in Staphylococcus aureus

    Ameya A Mashruwala et al.
    The absence of oxygen prompts Staphylococcus aureus cells to rupture resulting in increased formation of biofilms, which are the etiological agents of recurrent infections.

    Tissue-autonomous immune response regulates stress signaling during hypertrophy

    Robert Krautz et al.
    The immune effector Drosomycin buffers stress signaling in hypertrophic salivary glands to inhibit their disintegration, detection by the cellular immune response, and promotes further overgrowth.

    Genome duplication in Leishmania major relies on persistent subtelomeric DNA replication

    Jeziel Dener Damasceno et al.
    Duplication of Leishmania chromosomes combines S-phase DNA replication initiated at a single internal region with subtelomeric DNA replication detectable outside S-phase, potentially explaining genome plasticity in this important parasite.

    Impact of COVID-19-related disruptions to measles, meningococcal A, and yellow fever vaccination in 10 countries

    Katy AM Gaythorpe et al.
    Routine and campaign vaccination disruption in 2020 may lead to measles outbreaks and yellow fever burden increases in some countries, but is unlikely to greatly increase meningococcal A burden.

    Light-dependent single-cell heterogeneity in the chloroplast redox state regulates cell fate in a marine diatom

    Avia Mizrachi et al.
    Single-cell analysis of the chloroplast redox response to high light and oxidative stress revealed light-dependent heterogeneity, and was linked to cell fate determination within isogenic diatom populations.

    Lives saved with vaccination for 10 pathogens across 112 countries in a pre-COVID-19 world

    Jaspreet Toor et al.
    Vaccination activities that occurred before the COVID-19 pandemic, 2000-2019, are estimated to avert 50 million deaths, highlighting the enormous benefits of continued and improving vaccination.
