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.
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.

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.

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.
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.

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.

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.

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.

Coral reef heterotrophic bacteria and fleshy macroalgae cause oxygen loss from reef systems through microbial biomass accumulation and ebullition from algae surfaces.
