    Mechanistic insights into robust cardiac IKs potassium channel activation by aromatic polyunsaturated fatty acid analogues

    Briana M Bohannon, Jessica J Jowais ... H Peter Larsson
    Changing substituents on the aromatic rings of polyunsaturated fatty acid analogues tailors their activation effect on the IKs channel and thus their therapeutic potential for long QT syndrome.

    A back-door insight into the modulation of Src kinase activity by the polyamine spermidine

    Sofia Rossini, Marco Gargaro ... Giada Mondanelli
    A road to modulators of the kinase activity and the non-enzymatic functions of Src and IDO1 at once.

    Flying squirrels use a mortise-tenon structure to fix nuts on understory twigs

    Han Xu, Lian Xia ... Suqin Fang
    Two flying squirrel species chewed grooves into Cyclobalanopsis nuts, and used them to pressure-fit nuts tightly in crotches formed by small twigs on understory plants, in a way similar to a mortise-tenon joint used in architecture and carpentry.

    Allosteric activation or inhibition of PI3Kγ mediated through conformational changes in the p110γ helical domain

    Noah J Harris, Meredith L Jenkins ... John E Burke
    Regulation of phosphoinositide 3 kinase (PI3Kγ) is essential in immune function, and stimuli that modulate the dynamics of the PI3Kγ helical domain can activate or inhibit kinase activity.
    1. Neuroscience

    A tradeoff between acoustic and linguistic feature encoding in spoken language comprehension

    Filiz Tezcan, Hugo Weissbart, Andrea E Martin
    Linguistic features are encoded more strongly during language comprehension than when comprehension is absent, and high word entropy (less constraining context) enhances the encoding of lower-level acoustic and linguistic features while low word entropy suppresses it.

    Vitamin B2 enables regulation of fasting glucose availability

    Peter M Masschelin, Pradip Saha ... Sean M Hartig
    The dietary vitamin riboflavin provides the chemical backbone to generate essential substrates that support liver glucose metabolism during low-nutrient conditions.

    The Opto-inflammasome in zebrafish as a tool to study cell and tissue responses to speck formation and cell death

    Eva Hasel de Carvalho, Shivani S Dharmadhikari ... Maria Leptin
    Manipulating cell death in situ with the temporal and spatial precision of optogenetic tools opens up new avenues for studying inflammation, death and related phenomena, revealing, for example, that epithelial cell death cannot be classified into strictly distinct categories.

    CCR4 and CCR7 differentially regulate thymocyte localization with distinct outcomes for central tolerance

    Yu Li, Pablo Guaman Tipan ... Lauren IR Ehrlich
    Two-photon microscopy, combined with chemotaxis assays, synchronized thymocyte selection studies, and flow cytometry analyses, reveal that CCR4 and CCR7 promote medullary entry and central tolerance of immature and mature post-positive selection thymocyte subsets, respectively, with distinct outcomes for central tolerance.
    1. Medicine

    Development and biophysical characterization of a humanized FSH–blocking monoclonal antibody therapeutic formulated at an ultra-high concentration

    Satish Rojekar, Anusha R Pallapati ... Mone Zaidi
    MS-Hu6 biotherapeutic formulation for the treatment of osteoporosis, obesity, and Alzheimer's disease.

    The ER folding sensor UGGT1 acts on TAPBPR-chaperoned peptide-free MHC I

    Lina Sagert, Christian Winter ... Robert Tampé
    The endoplasmic reticulum (ER) folding sensor UGGT1 essentially cooperates with the peptide editor TAPBPR to provide quality control of MHC I molecules in the antigen presentation pathway.
