    Kinetics of the LOV domain of ZEITLUPE determine its circadian function in Arabidopsis

    Ashutosh Pudasaini et al.
    In the plant circadian clock photoreceptor ZEITLUPE, evolutionarily selected residues distinguish photocycle kinetics and allosteric signal transduction pathways to permit proper circadian timing.

    Male meiotic spindle features that efficiently segregate paired and lagging chromosomes

    Gunar Fabig et al.
    Chromosome segregation in male spermatocytes exhibits anaphase A without shortening of autosome-associated microtubules and partitioning of an unpaired X chromosome that is initiated by an imbalance of attached kinetochore microtubules.

    Blue light-induced LOV domain dimerization enhances the affinity of Aureochrome 1a for its target DNA sequence

    Udo Heintz, Ilme Schlichting
    Light absorption by the algal transcription factor Aureochrome 1a causes dimerization at the light-oxygen-voltage (LOV) sensing domain, which has implications for the design of synthetic photoreceptors for optogenetics.

    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.

    Trends in snakebite deaths in India from 2000 to 2019 in a nationally representative mortality study

    Wilson Suraweera et al.
    Prevention and antivenom treatment could reduce snakebite deaths, which killed 1.2 million Indians from 2000-2019, about 70% of which occurred in eight states, and half during four rainy months.

    Tight nuclear tethering of cGAS is essential for preventing autoreactivity

    Hannah E Volkman et al.
    Tight nuclear tethering of the cGAS DNA sensor maintains it in its resting state and prevents activation by self-DNA.

    Cyclic bouts of extreme bradycardia counteract the high metabolism of frugivorous bats

    M Teague O'Mara et al.
    Novel heart rate strategies that minimize energy expenditure during the day are necessary to cope with high energy nocturnal lifestyles of tent-making bats.

    Integration of light and metabolic signals for stem cell activation at the shoot apical meristem

    Anne Pfeiffer et al.
    TOR kinase guides the transition of plant stem cells from the dormant embryonic state to the active adult state by integrating light and metabolic signals.

    Functional trade-offs and environmental variation shaped ancient trajectories in the evolution of dim-light vision

    Gianni M Castiglione, Belinda SW Chang
    The evolution of the light-sensitive visual pigment rhodopsin involved functional tradeoffs that may have sacrificed rod photosensitivity for active-state protein stability to mitigate phototoxicity in tetrapods, but not in fishes.

    Evolution of C4 photosynthesis predicted by constraint-based modelling

    Mary-Ann Blätke, Andrea Bräutigam
    Constraint-based modelling predicts C4 photosynthesis evolves under resource limitation from an ancestral ground state of C3 photosynthesis and attributes divergent metabolic routes in extant C4 subtypes to light.
