    Carbon recovery dynamics following disturbance by selective logging in Amazonian forests

    Camille Piponiot, Plinio Sist ... Bruno Hérault
    Carbon recovery in Amazonian forests disturbed by selective logging is higher in the Guiana Shield and in the west, and is mainly shaped by the carbon gain of trees that survived the disturbance.

    RETRACTED: Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

    'Palaeoshellomics’ reveals the use of freshwater mother-of-pearl in prehistory

    Jorune Sakalauskaite, Søren H Andersen ... Beatrice Demarchi
    Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.

    Acute perturbation of Pet1-neuron activity in neonatal mice impairs cardiorespiratory homeostatic recovery

    Ryan T Dosumu-Johnson, Andrea E Cocoran ... Susan M Dymecki
    Pet1 neurons actively maintain cardiorespiratory tone and dynamic range in mouse neonates and critically support the recovery response to apneas, informing brain findings in the sudden infant death syndrome.

    Recovery of consciousness and cognition after general anesthesia in humans

    George A Mashour, Ben JA Palanca ... Max B Kelz
    Cognitive reconstitution after pharmacologic unconsciousness is an extended process, executive function is more robust than expected, and the healthy human brain is resilient to the effects of deep general anesthesia.

    A dynamic rhizosphere interplay between tree roots and soil bacteria under drought stress

    Yaara Oppenheimer-Shaanan, Gilad Jakoby ... Tamir Klein
    Increased root exudation rate under combined drought and bacterial inoculation and bacterial growth stimulation by specific exudation metabolites support the idea of root recruitment of beneficial bacteria, especially under water stress.

    SWI/SNF senses carbon starvation with a pH-sensitive low-complexity sequence

    J Ignacio Gutierrez, Gregory P Brittingham ... Liam J Holt
    A combination of single-cell analysis, genomics, and simulations shows that a glutamine-rich low-complexity sequence in the SWI/SNF chromatin remodeling complex senses transient intracellular acidification as a signal for cells to switch their global transcriptional program.

    Protein gradients on the nucleoid position the carbon-fixing organelles of cyanobacteria

    Joshua S MacCready, Pusparanee Hakim ... Daniel C Ducat
    Carboxysomes, the carbon-fixation machinery of cyanobacteria, are equidistantly-positioned by dynamic gradients of the protein McdA on the nucleoid that emerge through interaction with a previously unidentified carboxysome factor, McdB.

    Biophysical and physiological processes causing oxygen loss from coral reefs

    Cynthia B Silveira, Antoni Luque ... Forest Rohwer
    Coral reef heterotrophic bacteria and fleshy macroalgae cause oxygen loss from reef systems through microbial biomass accumulation and ebullition from algae surfaces.
