    The effect of host community functional traits on plant disease risk varies along an elevational gradient

    Fletcher W Halliday, Mikko Jalo, Anna-Liisa Laine
    Environmental gradients can modify a fundamental relationship between host community structure and disease, with implications for predicting disease risk in a changing world.

    Profound regulation of Na/K pump activity by transient elevations of cytoplasmic calcium in murine cardiac myocytes

    Fang-Min Lu, Christine Deisl, Donald W Hilgemann
    Transient Ca elevations of cytoplasmic calcium in cardiac myocytes profoundly activate cardiac Na/K pump activity in parallel with physical-chemical changes of the sarcolemma but without involvement of conventional signaling mechanisms.

    Climate-mediated cooperation promotes niche expansion in burying beetles

    Syuan-Jyun Sun, Dustin R Rubenstein ... Sheng-Feng Shen
    Cooperation enables burying beetles to outcompete flies and adapt to a wider range of temperatures as thermal generalists.

    Linking rattiness, geography and environmental degradation to spillover Leptospira infections in marginalised urban settings: An eco-epidemiological community-based cohort study in Brazil

    Max T Eyre, Fábio N Souza ... Federico Costa
    While flooding events may drive spillover transmission of Leptospira spp. through dispersal of the bacteria at low elevations, at higher elevations environmental risk is more localised and directly driven by the distribution of local rat reservoir populations.

    Gut microbiota induces high platelet response in patients with ST segment elevation myocardial infarction after ticagrelor treatment

    Xi Zhang, Xiaolin Zhang ... Yaling Han
    After myocardial infarction, gut microbiota affects platelet aggregation rate by regulating the absorption and metabolism of ticagrelor.

    Gene expression plasticity followed by genetic change during colonization in a high-elevation environment

    Huishang She, Yan Hao ... Yanhua Qu
    An integrative approach allows investigations of the relationship between an initial plasticity and the subsequent adaptive evolution during rapid adaptive modification of complex systems in the wild.
    1. Ecology

    Antagonistic effects of intraspecific cooperation and interspecific competition on thermal performance

    Hsiang-Yu Tsai, Dustin R Rubenstein ... Sheng-Feng Shen
    By integrating theoretical and empirical approaches, the results show that linking abiotic factor and biotic interactions on the niche width will be critical for understanding species-specific responses to climate change.
    1. Neuroscience

    Elevating acetyl-CoA levels reduces aspects of brain aging

    Antonio Currais, Ling Huang ... Pamela Maher
    A novel neuroprotective pathway that enhances acetyl-CoA metabolism via inhibition of acetyl-CoA carboxylase 1 may prevent the contribution of the aging process in the brain to Alzheimer's disease.
    1. Structural Biology and Molecular Biophysics

    Mechanism of substrate binding and transport in BASS transporters

    Patrick Becker, Fiona Naughton ... Alexander D Cameron
    The putative substrate pantoate binds to a sodium-coupled secondary transporter of the bile acid sodium symporter family, with sodium-dependent binding and conformational changes consistent with an elevator mechanism of transport.
    1. Immunology and Inflammation

    Pulsed ultrasound promotes secretion of anti-inflammatory extracellular vesicles from skeletal myotubes via elevation of intracellular calcium level

    Atomu Yamaguchi, Noriaki Maeshige ... Hidemi Fujino
    Ultrasound promotes release of extracellular vesicles from cultured myotubes and elicits anti-inflammatory effects on macrophages, indicating the potential of ultrasound stimulation to muscle for anti-inflammatory purposes.
