    APOE4 is associated with elevated blood lipids and lower levels of innate immune biomarkers in a tropical Amerindian subsistence population

    Angela R Garcia, Caleb Finch ... Benjamin C Trumble
    The relationship between APOE genotype and disease risks may be environmentally moderated, with APOE4 being less harmful and unlikely to increase cardiometabolic risk in a physically active, energy-limited population.

    A florigen paralog is required for short-day vernalization in a pooid grass

    Daniel Woods, Yinxin Dong ... Richard Amasino
    In Brachypodiumdistachyon, a single locus accounts for natural variation in whether perception of short day-lengths confers competence to flower.

    Hypoxia truncates and constitutively activates the key cholesterol synthesis enzyme squalene monooxygenase

    Hudson W Coates, Isabelle M Capell-Hattam ... Andrew J Brown
    Hypoxic accumulation of squalene, the substrate of squalene monooxygenase, triggers its proteasomal truncation to a constitutively active variant that preserves downstream sterol synthesis.

    Locally adaptive temperature response of vegetative growth in Arabidopsis thaliana

    Pieter Clauw, Envel Kerdaffrec ... Magnus Nordborg
    Growth of Arabidopsis seedlings at low temperatures differs between plants that hail from different parts of the world in a way that suggests climate adaptation.

    A highly tunable dopaminergic oscillator generates ultradian rhythms of behavioral arousal

    Ian D Blum, Lei Zhu ... Kai-Florian Storch
    An internal clock based on brain levels of dopamine works with the circadian clock to maintain daily patterns of alertness and activity, and may be implicated in the altered behavioral patterns seen in schizophrenia and bipolar disorder.

    Thermal acclimation of tropical coral reef fishes to global heat waves

    Jacob L Johansen, Lauren E Nadler ... Jodie Rummer
    The ability of animals to adjust to thermal stress is critical for survival under global warming, yet the adjustment process and scope have (until now) remained obscure in marine fishes.

    Natural genetic variation in Arabidopsis thaliana defense metabolism genes modulates field fitness

    Rachel Kerwin, Julie Feusier ... Daniel J Kliebenstein
    Environmental heterogeneity may contribute to the high levels of genetic variation in glucosinolate genes found in Arabidopsis thaliana.

    Gut microbe-targeted choline trimethylamine lyase inhibition improves obesity via rewiring of host circadian rhythms

    Rebecca C Schugar, Christy M Gliniak ... Jonathan Mark Brown
    Small molecule inhibitors of gut microbial choline trimethylamine lyase activity protect against obesity.

    A new class of cyclin dependent kinase in Chlamydomonas is required for coupling cell size to cell division

    Yubing Li, Dianyi Liu ... James G Umen
    CDKG1 is a D-cyclin dependent retinoblastoma related protein kinase whose abundance scales with cell size and controls cell division cycle number during multiple fission.
