Haze cools Pluto's atmosphere p.302

Modelling suggests that Pluto's atmospheric temperature is regulated by haze, unlike the other planetary bodies in the Solar System. The finding has implications for our understanding of exoplanetary atmospheres. See Letter p.352

Bacteria disarm host-defence proteins p.303

Infection with Shigella flexneri bacteria is a major cause of infant death. It emerges that S. flexneri evades intracellular defences by releasing a protein that triggers the destruction of members of a key family of host enzymes. See Letter p.378

Ocean hotspots of nitrogen loss p.305

Microbial activity in the sea results in a loss of bioavailable nitrogen. It emerges that the climate phenomenon called the El Niño–Southern Oscillation has a surprisingly large effect on the size of this loss.

Transgenic stem cells replace skin p.306

The treatment of a patient affected by an incurable genetic skin disease demonstrates the efficacy, feasibility and safety of replacing almost the whole skin using genetically corrected stem cells. See Letter p.327

The buoyancy of Earth's deep mantle p.308

The physical nature of two regions called large low-shear-velocity provinces at the base of Earth's mantle is uncertain. A measurement of their density has implications for our understanding of mantle dynamics. See Article p.321

The effect of conservation spending p.309

Statistical analysis of data on threatened species provides a model that can predict how rates of investment in conservation affect biodiversity under changing human population levels and agricultural and economic conditions. See Letter p.364

A broadly protective antibody p.310

A single antibody uses multiple antiviral mechanisms to block the replication of influenza B viruses in mice and ferrets. The development could inform research into improved flu vaccines.

Tidal tomography constrains Earth’s deep-mantle buoyancy p.321

An estimate of Earth’s deep-mantle buoyancy is derived from GPS-based measurements of body tide deformation and shown to be dominated by dense material possibly related to subducted oceanic plates or primordial rock.

Inflammation-induced IgA+ cells dismantle anti-liver cancer immunity p.340

IgA+ B cells expressing programmed death ligand 1 (PD-L1) and interleukin 10 accumulate in the inflamed livers of humans and mice with non-alcoholic fatty liver disease where they promote the progression to hepatocellular carcinoma by limiting the local activation of PD-1-expressing CD8+ T cells.

Granular materials flow like complex fluids p.360

The relaxation dynamics of granular materials is more like that of complex fluids than that of thermal glass-forming systems, owing to the absence of the ‘cage effect’.

Reductions in global biodiversity loss predicted from conservation spending p.364

Empirical two-part models describe the relationship between conservation spending, human development pressures and biodiversity loss and can inform sustainable development strategies by predicting the effects of financing decisions on future biodiversity losses.

Parallel palaeogenomic transects reveal complex genetic history of early European farmers p.368

In European Neolithic populations, the arrival of farmers prompted admixture with local hunter-gatherers over many centuries, resulting in distinct signatures in each region due to a complex series of interactions.

A ubiquitin-dependent signalling axis specific for ALKBH-mediated DNA dealkylation repair p.389

A signalling mechanism in human cells for sensing DNA damage induced by alkylation involves ubiquitin-dependent recruitment of the alkylation repair complex ASCC to the vicinity of the damage and co-localization with transcription and splicing factors.
