Clarke, Jason Alicea and Kirill Shtengel | | | Non-Abelian anyons are exotic quasiparticles envisioned to be promising candidates for solid-state quantum computation. Clarke et al. propose a device fabricated from fractional quantum Hall states and superconductors that supports a new type of non-Abelian defect that binds parafermionic zero modes. | | | 08 Jan | Nat Commun 4:1348 doi:10.1038/ncomms2340 (2013) | | | Physical sciences Condensed matter | | | Theoretical physics | | Abstract | Full Text | PDF (559 kB) |

| Kinship reduces alloparental care in cooperative cichlids where helpers pay-to-stay | | | Markus Zöttl, Dik Heg, Noémie Chervet and Michael Taborsky | | | In alloparental brood care, individuals help raise the offspring of others and it is thought that high relatedness between the helpers and recipients is needed. In contrast, Zöttl et al. find that, in cooperatively breeding cichlids, unrelated subordinate females provide more alloparental care than related ones. | | | 08 Jan | Nat Commun 4:1341 doi:10.1038/ncomms2344 (2013) | | | Biological sciences Ecology | | | Zoology | | Abstract | Full Text | PDF (419 kB) |

Ruiz-Jaen, Mats Fröberg, Johan Stendahl, Christopher D. Philipson, Grzegorz Mikusiński, Erik Andersson, Bertil Westerlund, Henrik Andrén, Fredrik Moberg, Jon Moen and Jan Bengtsson | | | Tree diversity is thought to benefit forest ecosystems, but evidence from large-scale studies is scarce. This study of a 400,000 km2 forest area shows that higher tree species richness supports higher levels of multiple ecosystem services, and therefore also a more sustainable management of production forests. | | | 08 Jan | Nat Commun 4:1340 doi:10.1038/ncomms2328 (2013) | | | Biological sciences Ecology | | | | Abstract | Full Text | PDF (1,038 kB) |

The authors demonstrate the use of charge transport in silicon nanomembranes to perform spectroscopy of the electronic structure of the surface states. | | | 08 Jan | Nat Commun 4:1339 doi:10.1038/ncomms2350 (2013) | | | Physical sciences Materials science Nanotechnology | | | Abstract | Full Text | PDF (706 kB) |

| Splicing factor SRSF3 is crucial for hepatocyte differentiation and metabolic function | | | Supriya Sen, Hassan Jumaa and Nicholas J. G. Webster | | | Splicing factors, such as the protein SRSF3, regulate mRNA metabolism but are hard to study in vivo because genetic kockouts are usually lethal. Here, Sen and colleagues create mice with a hepatocyte-specific knockout of Srsf3 and demonstrate its role in hepatocyte differentiation and liver function. | | | 08 Jan | Nat Commun 4:1336 doi:10.1038/ncomms2342 (2013) | | | Biological sciences Cell biology | | | Molecular biology | | Abstract | Full Text | PDF (2,863 kB) |

Duffy, Martina Helfen, Frank Edenhofer, Paul A. de Sousa and Mark Bradley | | | To transfer cultured human embryonic stem cells (hESCs) between culture dishes, cells need to be released using mechanical, enzymatic or chemical means, which can damage cells. Zhang et al. describe a thermomodulatable hydrogel that allows gentle, reagent-free cell passaging for the long-term culture of hESCs. | | | 08 Jan | Nat Commun 4:1335 doi:10.1038/ncomms2341 (2013) | | | Biological sciences Cell biology | | | | Abstract | Full Text | PDF (1,872 kB) |

Schiffer, S. D. Brown, C. J. Fennie and D. G.

Ryan et al. demonstrate that europium titanate under moderate strain exhibits strong magnetoelectric coupling that could be valuable to this endeavour. | | | 08 Jan | Nat Commun 4:1334 doi:10.1038/ncomms2329 (2013) | | | Physical sciences Condensed matter | | | Abstract | Full Text | PDF (1,376 kB) |

Schneider, Matthias F. Schneider and Alfredo Alexander-Katz | | | Blood clotting is caused by biopolymer-mediated aggregation of platelets and is enhanced by fast shear flows. Chen et al. find a similar process that arises during the self-assembly of polymer–colloid composites—a process that can be controlled and even reversed by flow rate and interparticle interaction. | | | 08 Jan | Nat Commun 4:1333 doi:10.1038/ncomms2326 (2013) | | | Physical sciences Biophysics | | | | Abstract | Full Text | PDF (1,329 kB) |

McDowell, Po-Chun Hsu and Yi Cui | | | The practical performance of lithium–sulphur batteries is lower than expected because of polysulphide dissolution into the electrolyte over time. Seh et al. show that a yolk–shell nanoarchitecture is able to encapsulate sulphur cathode materials efficiently and thus allows over 1,000 charge/discharge cycles. | | | 08 Jan | Nat Commun 4:1331 doi:10.1038/ncomms2327 (2013) | | | Chemical sciences Materials science | | | Nanotechnology | | Abstract | Full Text | PDF (1,086 kB) |
