Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17821-1Autosomal dominant optic atrophy is caused by mutations in the mitochondrial fusion protein OPA1. Here, the authors show that AMPK-induced autophagy depletes mitochondria in axons of retinal ganglion cells and that autophagic inhibition reverses vision loss in a mouse model.

Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17870-6Sensory information processing in robots relies on a centralized approach with issues of wiring, fault-tolerance and latency. Here, the authors report a decentralized neuromorphic approach with self-healable memristive elements enabling intelligent sensations in a prototypical robotic nervous system.

Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17877-zHigh stretchability, low hysteresis and anti-fatigue fracture are essential for hydrogel-based devices but it is rare to achieve. Here the authors demonstrate a hydrogel design using tandem-repeat proteins as the cross-linkers and random coiled polymers as the percolating network which results in high stretchability, low hysteresis and high fracture toughness.

Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17745-wThe reaction trajectories of photoexcited molecules may involve transitions through conical intersections, which are ubiquitous in nature but challenging to characterize. Here the authors provide a complete mapping of molecular dissociation of two model alkyl halides by ultrafast XUV transient absorption.

Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17705-4The mitochondrial calcium uptake system, crucial for cellular processes, evolved in ancient eukaryotes. Here, authors perform a phylogenomic analysis across 1,156 eukaryotes, and show that previously identified animal and fungal genes in this system originated from an ancestral duplication.

Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17790-5Soil microbial communities remain active throughout much of the Arctic winter, and Arctic winters are warming dramatically. Here, the authors show that persistently warm winter soils can lead to labile carbon starvation and reduced microbial respiration, despite the high carbon content of most Arctic soils.

Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17689-1The nori producing seaweed Pyropia yezoensis has heteromorphic generations that occupy distinct habitats. Here, via genome assembly, transcriptome analysis, and 13 C isotope labeling, the authors show the interplay between inorganic carbon availability and life cycle evolution in the intertidal environment.

Nature Communications, Published online: 12 August 2020; doi:10.1038/s41467-020-17854-6The hippocampus is thought to underlie income gaps in children’s cognition. Here, the authors find that the stress-sensitive anterior (but not posterior) hippocampus mediates income-gaps in memory and vocabulary, especially in children whose families earn ≤$75k annually.
