Pluto's telltale heart p.42

Studies of a large frost-filled basin on Pluto show that this feature altered the dwarf planet's spin axis, driving tectonic activity on its surface, and hint at the presence of a subsurface ocean. See Letters p.86, p.90, p.94 & p.97

Double agents for mitochondrial division p.43

Mitochondrial organelles — the energy powerhouses of the cell — must divide and fuse dynamically to function. It emerges that two distinct dynamin enzymes enable mitochondrial division. See Letter p.139

Efficient fault tolerance p.44

Dealing with errors in a quantum computer typically requires complex programming and many additional quantum bits. A technique for controlling errors has been proposed that alleviates both of these problems.

Sort of unexpected p.45

To reach the cell surface, membrane proteins are first targeted to an organelle called the endoplasmic reticulum. Several targeting pathways are known, but it now emerges that there is yet another pathway. See Letter p.134

Projections of the soil-carbon deficit p.47

Changes in the amount of carbon stored in soil might be a crucial feedback to climate change. Experimental field studies show that warming-induced soil carbon losses are greatest where carbon stocks are largest. See Letter p.104

A black hole changes its feeding habits p.48

In the 1980s, the gas surrounding a black hole in a nearby galaxy began to emit much more radiation than before. This change has unexpectedly reversed in the past five years, questioning our understanding of these extreme phenomena.

Wild times p.49

Little is known about the biological rhythms that emerge from social behaviours in the wild. A study of shorebird pairs shows that rhythms of nest-incubation duties are mainly governed by strategies to avoid predators. See Letter p.109

Stem cells and interspecies chimaeras p.51

A comprehensive review into mammalian interspecies chimaeras, documenting the advances that have occurred alongside developments in stem-cell biology and assessing the future of the field, including any possible ethical and legal issues.

Organization and functions of mGlu and GABAB receptor complexes p.60

This Review discusses current knowledge of the structure, function and interactions of the metabotropic glutamate and GABAB receptors and the potential to target receptor subunits for future therapeutic intervention in neurological and mental health disorders.

Ghost imaging with atoms p.100

Ghost imaging is demonstrated using beams of correlated pairs of ultracold helium atoms, rather than photons, yielding a reconstructed image with submillimetre resolution.

Unexpected diversity in socially synchronized rhythms of shorebirds p.109

Socially synchronized rhythms in shorebirds were assessed during biparental incubation under natural circumstances and were exceptionally diverse, often not following the 24-h day, whereby risk of predation, not starvation, determined some of the variation in incubation rhythms.

Genomic evolution and chemoresistance in germ-cell tumours p.114

Genomic analyses show that primary germ-cell tumours are highly enriched for chromosomal reciprocal loss of heterozygosity, mutations in KRAS and have high mitochondrial priming, providing insight into chemosensitivity and the evolution of chemoresistance in this disease.
