   The IRE1/XBP1 signaling axis promotes skeletal muscle regeneration through a cell non-autonomous mechanism

   Anirban Roy et al.

   The IRE1/XBP1 signaling in myofibers is essential for robust skeletal muscle regeneration in response to injury.

   A nanocompartment system contributes to defense against oxidative stress in Mycobacterium tuberculosis

   Katie A Lien et al.

   A peroxidase-containing nanocompartment in the bacterial pathogen Mycobacterium tuberculosis protects against oxidative stress and antibiotic treatment in the host.

   Motor memories of object dynamics are categorically organized

   Evan Cesanek et al.

   The motor-relevant properties of the myriad objects with which we interact on a daily basis are encoded in memory using categorical representations, or 'object families'.

   Branched ubiquitin chain binding and deubiquitination by UCH37 facilitate proteasome clearance of stress-induced inclusions

   Aixin Song et al.

   Through interactions with both ubiquitin units that emanate from a branch point in polyubiquitin, UCH37 recognizes and hydrolyzes branched chains to promote proteasome-mediated degradation upon proteolytic stresses.

   Markov state models of proton- and pore-dependent activation in a pentameric ligand-gated ion channel

   Cathrine Bergh et al.

   Computational models of gating processes in an ion channel show how stability shifts upon ligand-binding and mutations are reproduced, which highlights mechanistic details and proposes a new role for symmetry in gating.

   Ca²⁺/CaM binding to CaMKI promotes IMA-3 importin binding and nuclear translocation in sensory neurons to control behavioral adaptation

   Domenica Ippolito et al.

   Ca²⁺-dependent nuclear entry of Ca²⁺/calmodulin-dependent protein kinase-1 in sensory neurons, taking place with a relatively slow kinetics, contributes to couple long-lasting sensory stimulations with signaling in the nucleus over a timescale relevant for sensory history-dependent plasticity.

   A recombinant protein containing influenza viral conserved epitopes and superantigen induces broad-spectrum protection

   Yansheng Li et al.

   By fusing influenza viral conserved epitopes and a superantigen fragment, we constructed a recombinant protein that might be a candidate universal broad-spectrum vaccine for the prevention and treatment of multiple influenza viruses.

   High rates of evolution preceded shifts to sex-biased gene expression in Leucadendron, the most sexually dimorphic angiosperms

   Mathias Scharmann et al.

   In the dioecious plant genus Leucadendron, shifts to sex-biased gene expression occurred predominantly in genes with ancestrally high rates of expression evolution, and were not correlated with morphology.

   The alpha/B.1.1.7 SARS-CoV-2 variant exhibits significantly higher affinity for ACE-2 and requires lower inoculation doses to cause disease in K18-hACE2 mice

   Rafael Bayarri-Olmos et al.

   Functional characterization of the alpha/B1.1.7 SARS-CoV-2 variant revealed an eightfold affinity increase of the N501Y RBD to human ACE-2 and that even a low inoculation dose of the alpha variant induces severe disease and fast progression in transgenic hACE2 mice.

    Efficacy of FFP3 respirators for prevention of SARS-CoV-2 infection in healthcare workers

    Mark Ferris et al.

    Healthcare workers working on COVID-19 wards experience a 31-fold increased risk of infection with SARS-CoV-2 compared to colleagues on non-COVID-19 wards whilst wearing fluid-resistant surgical masks, and FFP3 respirators provide up to 100% protection against infection.
