    A novel single alpha-helix DNA-binding domain in CAF-1 promotes gene silencing and DNA damage survival through tetrasome-length DNA selectivity and spacer function

    Ruben Rosas, Rhiannon R Aguilar ... Mair EA Churchill
    The lysine/glutamic acid/arginine region in chromatin assembly factor (CAF-1) forms a long single alpha-helix DNA-binding domain, facilitating the recognition of tetrasome-length DNA and linking functional domains within the CAF-1 architecture for efficient tetrasome assembly after DNA synthesis.

    Temperature sensitivity of the interspecific interaction strength of coastal marine fish communities

    Masayuki Ushio, Testuya Sado ... Masaki Miya
    Fish environmental DNA remaining in a cup of seawater provides information about interaction strengths among marine fish species in nature, highlighting the potential impact of global climate change on community dynamics and stability.

    Target cell-specific synaptic dynamics of excitatory to inhibitory neuron connections in supragranular layers of human neocortex

    Mean-Hwan Kim, Cristina Radaelli ... Ed Lein
    Electrophysiological study in human brain slices reveals that short-term synaptic plasticity from presynaptic pyramidal neuron to postsynaptic interneuron connections are target-cell specific based on their subclass interneuron identity.

    Flexible specificity of memory in Drosophila depends on a comparison between choices

    Mehrab N Modi, Adithya E Rajagopalan ... Glenn C Turner
    Flies can optimally recall a memory with high specificity by comparing options close in time, or default to generalization when they cannot.

    MYC overrides HIF-1α to regulate proliferating primary cell metabolism in hypoxia

    Courtney A Copeland, Benjamin A Olenchock ... William M Oldham
    Hypoxia does not increase glycolysis in proliferating primary cells and antagonizes the increase in glycolysis caused by activation of hypoxia-inducible factor in normoxia, in part, through activation of MYC signaling pathways.

    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.

    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.
