    Irreversible temperature gating in trpv1 sheds light on channel activation

    Ana Sánchez-Moreno et al.
    Temperature-activated TRPV1 ion channels respond to increased temperatures by opening and then entering an inactivated state from which they cannot recover, suggesting that this form of irreversible gating results from partial unfolding during heat absorption.

    The diversity of floral temperature patterns, and their use by pollinators

    Michael JM Harrap et al.
    Flowers of different plant species show distinct and highly diverse patterns of temperature across their surfaces, and bumblebees are able to differentiate between these previously unnoticed but widespread floral cues.

    High temperature sensitivity is intrinsic to voltage-gated potassium channels

    Fan Yang, Jie Zheng
    Highly temperature-sensitive behavior of voltage-gated potassium channels provides a mechanistic model for how heat-activated TRP channels serve as temperature and pain sensors.

    Cell-intrinsic mechanisms of temperature compensation in a grasshopper sensory receptor neuron

    Frederic A Roemschied et al.
    The firing rates of neurons in the grasshopper auditory system are surprisingly robust to changes in temperature, and cell-intrinsic mechanisms are sufficient to explain this temperature insensitivity.

    The role of PDF neurons in setting the preferred temperature before dawn in Drosophila

    Xin Tang et al.
    In Drosophila, key neurons controlling sleep play an important role in adjusting the temperature set-point before dawn via time-dependent neuronal plasticity within the clock circuits.

    TRPV4 is the temperature-sensitive ion channel of human sperm

    Nadine Mundt et al.
    The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.

    No general relationship between mass and temperature in endothermic species

    Kristina Riemer et al.
    Data analysis of a large number of species indicates that a negative temperature-mass relationship is not common among species, which has been an ecological assumption for over a century.

    Preoptic leptin signaling modulates energy balance independent of body temperature regulation

    Sangho Yu et al.
    The preoptic area (POA) regulates distinct metabolic adaptations, via leptin-dependent (fasting-induced hypometabolism and high-fat-diet-induced hypermetabolism), or leptin-independent mechanisms (temperature induced metabolic changes) and thus significantly contributes to body weight homeostasis.

    Natural haplotypes of FLM non-coding sequences fine-tune flowering time in ambient spring temperatures in Arabidopsis

    Ulrich Lutz et al.
    Gene expression changes associated with polymorphisms in non-coding sequences of the flowering time regulator FLM directly influence flowering time in ambient temperature in Arabidopsis over an extended vegetative period.
