    Mechanisms and functions of respiration-driven gamma oscillations in the primary olfactory cortex

    Joaquin Gonzalez, Pablo Torterolo, Adriano BL Tort
    Computational analyses of in-vivo cerebral activity show that gamma oscillations in the olfactory cortex originate from local feedback inhibition following each sniff and serve to segregate competing odor representations through a winner-take-all process, providing an optimal window to decode odor.

    Assessing healthy vaccinee effect in COVID-19 vaccine effectiveness studies: a national cohort study in Qatar

    Hiam Chemaitelly, Houssein H Ayoub ... Laith J Abu-Raddad
    A pronounced and consistent healthy vaccinee effect has been identified in rigorously conducted vaccine effectiveness studies, specifically within the first 6 months post-vaccination and among older or clinically vulnerable individuals, likely driven by lower vaccination rates among severely ill populations.

    HNF1A is a novel oncogene that regulates human pancreatic cancer stem cell properties

    Ethan V Abel, Masashi Goto ... Diane M Simeone
    HNF1A, a risk factor gene for pancreatic ductal adenocarcinoma, is critical to maintaining pancreatic cancer stem cell properties through regulating POU5F1 (OCT4) expression, providing a novel role for HNF1A in maintenance of the disease.

    Imaging single-cell blood flow in the smallest to largest vessels in the living retina

    Aby Joseph, Andres Guevara-Torres, Jesse Schallek
    By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.

    Noncoding RNA-nucleated heterochromatin spreading is intrinsically labile and requires accessory elements for epigenetic stability

    R A Greenstein, Stephen K Jones ... Bassem Al-Sady
    Heterochromatin spreading in fission yeast predominantly produces intergenerationally unstable outcomes, requiring an accessory element that represses histone turnover.

    Bilateral regulation of EGFR activity and local PI(4,5)P2 dynamics in mammalian cells observed with superresolution microscopy

    Mitsuhiro Abe, Masataka Yanagawa ... Yasushi Sako
    The local PI(4,5)P2 nanodomain promotes the dimerization and activation of EGFR in the plasma membrane, whereas activated EGFR dissolves the nanodomain structure of PI(4,5)P2 through PLCγ.

    Structural basis for the assembly of the mitotic motor Kinesin-5 into bipolar tetramers

    Jessica E Scholey, Stanley Nithianantham ... Jawdat Al-Bassam
    The Bipolar Assembly domain of kinesin-5 comprises an anti-parallel four-helix bundle, which explains how kinesin-5 subunits assemble into bipolar tetramers with two motile ends that transmit forces while crosslinking and sliding adjacent microtubules during mitosis.

    Label-free imaging of immune cell dynamics in the living retina using adaptive optics

    Aby Joseph, Colin J Chu ... Jesse Schallek
    Immune cell motility and vascular response are imaged in vivo and label free in the CNS for the first time, using high-resolution phase-contrast adaptive optics retinal imaging.

    Tubulin cofactors and Arl2 are cage-like chaperones that regulate the soluble αβ-tubulin pool for microtubule dynamics

    Stanley Nithianantham, Sinh Le ... Jawdat Al-Bassam
    Soluble αβ-tubulin assembly is regulated by a cage-like molecular complex containing tubulin cofactors and Arl2.

    A single K+-binding site in the crystal structure of the gastric proton pump

    Kenta Yamamoto, Vikas Dubey ... Kazuhiro Abe
    Crystal structures provide structural rationales for the transport stoichiometry of the gastric proton pump, which suffices the energy requirement for the generation of a million-fold proton gradient across the membrane.
