Sreeprasad, Ashvin Nagaraja, Alfredo Alexander Rodriguez and Vikas Berry | | | Current top-down and bottom-up syntheses of graphene nanostructures suffer from low yields or do not produce structures with different and controlled shapes. Here, monodisperse graphene shapes are produced by diamond-edge cutting of pyrolytic graphite followed by exfoliation. | | | 15 May | Nat Commun 3:844 doi:10.1038/ncomms1834 (2012) | | | Chemical sciences Materials science | | | Nanotechnology | | Abstract | Full Text | PDF (2,233 kB) |

| Environmental noise exposure degrades normal listening processes | | | Xiaoming Zhou and Michael M. Merzenich | | | The damaging effects of loud noise on auditory function are well established, but the effects of low-level noise are not so well understood. Zhou and Merzenich chronically expose adult rats to structured low-level noise and find that it causes auditory cortex damage and sound discrimination impairment. | | | 15 May | Nat Commun 3:843 doi:10.1038/ncomms1849 (2012) | | | Biological sciences Neuroscience | | | | Abstract | Full Text | PDF (952 kB) |

| Serine-7 but not serine-5 phosphorylation primes RNA polymerase II CTD for P-TEFb recognition OPEN | | | Nadine Czudnochowski, Christian A. Bösken and Matthias Geyer | | | Phosphorylation of the carboxy-terminal domain of RNA polymerase II is important for controlling gene transcription. In this study, the transcription elongation factor Tefb is shown to phosphorylate serine-5 and its activity is enhanced when the polymerase is already phosphorylated on serine-7. | | | 15 May | Nat Commun 3:842 doi:10.1038/ncomms1846 (2012) | | | Biological sciences Biochemistry | | | Molecular biology | | Abstract | Full Text | PDF (1,188 kB) |

Dougalis, Vincenzo de Paola, Mark A. Ungless, Meng Li and Tristan A. Rodríguez | | | Signalling inputs to neural progenitors regulate the differentiation of the stem cell pool. By analysing the mechanisms occuring during neurogenesis, Cambray et al. report that activin is the pivotal factor regulating the differentiation of telencephalic neural precursors towards a cortical interneuron fate. | | | 15 May | Nat Commun 3:841 doi:10.1038/ncomms1817 (2012) | | | Biological sciences Neuroscience | | Abstract | Full Text | PDF (1,734 kB) |

| Symbiont fidelity and the origin of species in fungus-growing ants OPEN | | | Natasha J. Mehdiabadi, Ulrich G. Mueller, Seán G. Brady, Anna G. Himler and Ted R. Schultz | | | Fungus-growing ants cultivate fungi for food, but it is unclear whether single ant and fungal species are exclusive to one another. This study of C. wheeleri ants and their fungi shows that each ant species has been associated with a single fungal cultivar species for millions of years and that ant speciation coincides with shifts in fungal use. | | | 15 May | Nat Commun 3:840 doi:10.1038/ncomms1844 (2012) | | | Biological sciences Ecology | | | Evolution | | Abstract | Full Text | PDF (561 kB) |

| Enamel-like apatite crown covering amorphous mineral in a crayfish mandible OPEN | | | Shmuel Bentov, Paul Zaslansky, Ali Al-Sawalmih, Admir Masic, Peter Fratzl, Amir Sagi, Amir Berman and Barbara Aichmayer | | | The compositional makeup of skeletons and teeth in invertebrates and vertebrates is generally different. This study examines the material composition and properties of freshwater crayfish mandibles and finds, in an unusual case of convergent evolution, that they are composed of an apatite layer that is similar to mammalian enamel. | | | 15 May | Nat Commun 3:839 doi:10.1038/ncomms1839 (2012) | | | Biological sciences Biochemistry | | | Biophysics Materials science | | Abstract | Full Text | PDF (1,120 kB) |

Using time-resolved X-ray diffraction at a free electron laser, Lee et al. investigate the charge order parameter in a striped nickelate. | | | 15 May | Nat Commun 3:838 doi:10.1038/ncomms1837 (2012) | | | Physical sciences Condensed matter | | | Materials science | | | | Abstract | Full Text | PDF (981 kB) |

| Developmentally based scaling of leaf venation architecture explains global ecological patterns OPEN | | | Lawren Sack, Christine Scoffoni, Athena D. McKown, Kristen Frole, Michael Rawls, J. Christopher Havran, Huy Tran and Thusuong Tran | | | The size of dicotyledon leaves and their venation vary enormously across ecosystems. In this study, using 485 plant species, scaling relationships are presented between vein traits and leaf size, and explained based on a developmental algorithm that demonstrates why smaller leaves persist in drier areas. | | | 15 May | Nat Commun 3:837 doi:10.1038/ncomms1835 (2012) | | | Biological sciences Ecology | | | Evolution | | | Plant sciences | | Abstract | Full Text | PDF (847 kB) |

| A crucial role for bone morphogenetic protein-Smad1 signalling in the DNA damage response | | | Jenny Fung Ling Chau, Deyong Jia, Zhongfeng Wang, Zhi Liu, Yuanyu Hu, Xin Zhang, Hao Jia, Keng Po Lai, Wai Fook Leong, Bi Jin Au, Yuji Mishina, Ye-Guang Chen, Christine Biondi, Elizabeth Robertson, Dong Xie, Huijuan Liu, Lin He, Xueying Wang, Qiang Yu and Baojie Li | | | The bone morphogenetic protein (BMP) and Smad1 signalling pathway is required for embryogenesis. In this study, Smad1 is shown to be phosphorylated by Atm in response to DNA damage and this results in elevated Smad1 signalling, thus uncovering a new role for this pathway in the DNA damage response. | | | 15 May | Nat Commun 3:836 doi:10.1038/ncomms1832 (2012) | | | Biological sciences Cancer | | | Cell biology Molecular biology | | Abstract | Full Text | PDF (1,743 kB) |

Leake, Stefanie Tille, Martin I. Bidartondo and David J. Beerling | | | Vascular plants with root systems evolved in the mid-Palaeozoic with symbiotic fungi. Field et al. show that in contrast to non-vascular plants lacking roots, the efficiency of plant–fungal symbiosis increased for vascular plants with root systems as carbon dioxide levels declined in the mid-Palaeozoic. | | | 15 May | Nat Commun 3:835 doi:10.1038/ncomms1831 (2012) | | | Biological sciences Ecology | | | Evolution Plant sciences | | | Abstract | Full Text | PDF (761 kB) |

| Giant nonlinear optical activity in a plasmonic metamaterial | | | Mengxin Ren, Eric Plum, Jingjun Xu and Nikolay I. Zheludev | | | Light propagating in a medium can undergo polarization rotation, an effect that depends on light intensity and chiral properties. Ren et al. report polarization rotation in a plasmonic metamaterial with million-fold stronger nonlinearity than that found in natural crystals. | | | 15 May | Nat Commun 3:833 doi:10.1038/ncomms1805 (2012) | | | Physical sciences Optical physics | | | Abstract | Full Text | PDF (817 kB) |
| The origin of pelletal lapilli in explosive kimberlite eruptions | | | T.M. Gernon, R.J. Brown, M.A. Tait and T.K. Hincks | | | Kimberlites are volatile-rich magmas that form diverging pipes containing pelletal lapilli - well rounded clasts that consist of an inner seed particle. Gernon et al. suggest that pelletal lapilli are formed when fluid volatile-rich melts intrude into earlier volcaniclastic infill close to the diatreme root zone. | | | 15 May | Nat Commun 3:832 doi:10.1038/ncomms1842 (2012) | | | Earth sciences Geology and geophysics | | | | | Abstract | Full Text | PDF (1,586 kB) |

Keimer and D.S. Inosov | | | Resonant magnetic excitations are common in unconventional superconductors, but the mechanism for their formation is elusive. Using inelastic neutron scattering, this study finds similar excitations in the non-superconducting heavy-fermion metal CeB6, suggesting common behaviour between the two ground states. | | | 15 May | Nat Commun 3:830 doi:10.1038/ncomms1821 (2012) | | | Physical sciences Condensed matter | | | Materials science | | | Abstract | Full Text | PDF (2,432 kB) | | | | | | |
