    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Conformational distributions of isolated myosin motor domains encode their mechanochemical properties

    Justin R Porter et al.
    Shifts in the balance between nucleotide-favorable and nucleotide-unfavorable conformations of myosin motors encode duty ratios and ADP release rates, demonstrating the power of an ensemble perspective for uncovering sequence-function relationships.

    Preparation for upcoming attentional states in the hippocampus and medial prefrontal cortex

    Eren Günseli, Mariam Aly
    Memory guides attention by enabling preparation for upcoming states in the hippocampus and medial prefrontal cortex.

    Accelerated phosphatidylcholine turnover in macrophages promotes adipose tissue inflammation in obesity

    Kasparas Petkevicius et al.
    Obesity leads to increased phosphatidylcholine turnover in adipose tissue macrophages that makes them susceptible to saturated fatty acid-induced inflammation.

    Olfactory connectivity mediates sleep-dependent food choices in humans

    Surabhi Bhutani et al.
    Sleep deprivation enhances energy-dense food choices and encoding of olfactory information in the human brain.

    Lack of activity of recombinant HIF prolyl hydroxylases (PHDs) on reported non-HIF substrates

    Matthew E Cockman et al.
    Assays using recombinant HIF prolyl hydroxylases did not support hydroxylation of more than 20 reported non-HIF substrates under conditions where robust HIF hydroxylation was observed.

    Drosophila macrophages switch to aerobic glycolysis to mount effective antibacterial defense

    Gabriela Krejčová et al.
    Activated Drosophila macrophages undergo transient metabolic remodeling towards Hypoxia inducible factor 1 α-driven aerobic glycolysis, a program that induces systemic metabolic changes and is crucial for resistance to infection.

    Apolipoprotein M-bound sphingosine-1-phosphate regulates blood–brain barrier paracellular permeability and transcytosis

    Mette Mathiesen Janiurek et al.
    Shortage of blood-borne apolipoprotein-M–bound sphingosine-1-phosphate, which accompanies various brain disorders, causes paracellular leak and increase in transcytosis at the blood–brain barrier, which can be reversed, thus is of clinical relevance.

    Chromatinization of Escherichia coli with archaeal histones

    Maria Rojec et al.
    Escherichia coli is surprisingly tolerant to chromatinization by archaeal histones, suggesting that histones can become established as ubiquitous chromatin proteins without interfering critically with some key DNA-templated processes.

    Balancing model-based and memory-free action selection under competitive pressure

    Atsushi Kikumoto, Ulrich Mayr
    People compete by trying to outsmart their opponents as long as they win, but show random behavior, and neural signs of suppressing knowledge about opponents’ strategies, when they lose.
