Yuen, Ping Zhong, Mahboobe Ghaedi, Zhixing Hu, Gissou Azabdaftari, Kazuhiro Nakaso, Zhen Yan and Jian Feng | | | Mutations in parkin, an ubiquitin ligase, cause an inherited form of Parkinson's disease. Here, Jiang et al. generate induced pluripotent stem cells from two patients with parkin mutations and find that neurons derived from the stem cells have defects in dopamine release, dopamine uptake and oxidative metabolism. | | | 07 Feb | Nat Commun 3:668 doi:10.1038/ncomms1669 (2012) | | | Biological sciences Cell biology | | | Medical research Neuroscience | | | | | Abstract | Full Text | PDF (1,928 kB) |

| EphB3 suppresses non-small-cell lung cancer metastasis via a PP2A/RACK1/Akt signalling complex | | | Guo Li, Xiao-Dan Ji, Hong Gao, Jiang-Sha Zhao, Jun-Feng Xu, Zhi-Jian Sun, Yue-Zhen Deng, Shuo Shi, Yu-Xiong Feng, Yin-Qiu Zhu, Tao Wang, Jing-Jing Li and Dong Xie | | | The role of ephrin receptors in tumour development and progression has remained controversial. Li et al. show that kinase activation of ephrin-B3 inhibits non-small-cell lung cancer migration both in vitro and in vivo, which depends on a novel interacting partner, RACK 1, in a ternary complex with PP2A and Akt. | | | 07 Feb | Nat Commun 3:667 doi:10.1038/ncomms1675 (2012) | | | Biological sciences Cancer | | | Cell biology | | Abstract | Full Text | PDF (1,147 kB) |

| Ultrafast heating as a sufficient stimulus for magnetization reversal in a ferrimagnet | | | T.A. Ostler, J. Barker, R.F.L. Evans, R.W. Chantrell, U. Atxitia, O. Chubykalo-Fesenko, S. El Moussaoui, L. Le Guyader, E. Mengotti, L.J. Heyderman, F. Nolting, A. Tsukamoto, A. Itoh, D. Afanasiev, B.A. Ivanov, A.M. Kalashnikova, K. Vahaplar, J. Mentink, A. Kirilyuk, Th. Rasing and A.V. Kimel | | | The dynamics of spin ordering in magnetic materials is of interest both from a fundamental and an applied point of view. Using a combination of numerical and experimental techniques, Ostler et al. show that the magnetization of a ferrimagnet can be reversed on a timescale of picoseconds solely by heating it. | | | 07 Feb | Nat Commun 3:666 doi:10.1038/ncomms1666 (2012) | | | Physical sciences Applied physics | | | Condensed matter | | Abstract | Full Text | PDF (548 kB) |

| Modification of the carboxy-terminal flanking region of a universal influenza epitope alters CD4+ T-cell repertoire selection OPEN | | | David K. Cole, Kathleen Gallagher, Brigitte Lemercier, Christopher J. Holland, Sayed Junaid, James P. Hindley, Katherine K. Wynn, Emma Gostick, Andrew K. Sewell, Awen M. Gallimore, Kristin Ladell, David A. Price, Marie-Lise Gougeon and Andrew Godkin | | | Epitopes presented by MHC-II molecules bind to T-cell receptors to activate CD4+ T cells. In this study, changes in the carboxy-terminal region of the influenza hemagglutinin epitope HA305-320 alters the strength of binding to the T-cell receptor, thus modulating T-cell receptor usage and activation. | | | 07 Feb | Nat Commun 3:665 doi:10.1038/ncomms1665 (2012) | | | Biological sciences Immunology | | | Molecular biology Virology | | Abstract | Full Text | PDF (878 kB) |

| Broadband light management using low-Q whispering gallery modes in spherical nanoshells | | | Yan Yao, Jie Yao, Vijay Kris Narasimhan, Zhichao Ruan, Chong Xie, Shanhui Fan and Yi Cui | | | Control of light absorption in optical devices, such as solar cells, can be achieved through resonant features like whispering gallery modes. Here, these modes are exploited in spherical silicon nanoshells to enhance absorption over a broad spectral range in nanometre-scale flexible layers. | | | 07 Feb | Nat Commun 3:664 doi:10.1038/ncomms1664 (2012) | | | Physical sciences Materials science | | | Nanotechnology Optical physics | | Abstract | Full Text | PDF (694 kB) |

| Emergent neutrality leads to multimodal species abundance distributions | | | Remi Vergnon, Egbert H. van Nes and Marten Scheffer | | | Empirical data suggest that species abundance distributions can have multiple modes, which is not predicted by existing theories. This study shows that the multimodal pattern is consistent with emergent neutrality, suggesting this theory could have a role in shaping natural communities. | | | 07 Feb | Nat Commun 3:663 doi:10.1038/ncomms1663 (2012) | | | Biological sciences Ecology | | | Evolution | | Abstract | Full Text | PDF (597 kB) |

| Imperfect interface of Beclin1 coiled-coil domain regulates homodimer and heterodimer formation with Atg14L and UVRAG OPEN | | | Xiaohua Li, Liqiang He, Ka Hing Che, Sarah F. Funderburk, Lifeng Pan, Nina Pan, Mingjie Zhang, Zhenyu Yue and Yanxiang Zhao | | | Beclin1 is a key regulator of VPS34-related processes, including autophagy. Li et al. solve the crystal structure of Beclin 1 CC domain, an antiparallel dimer that is rendered metastable by a series of a-d' pairings, which determines its ability to form distinct heterodimers either with Atg14L or UVRAG. | | | 07 Feb | Nat Commun 3:662 doi:10.1038/ncomms1648 (2012) | | | Biological sciences Biochemistry | | Abstract | Full Text | PDF (1,273 kB) |

| Generation and control of polarization-entangled photons from GaAs island quantum dots by an electric field OPEN | | | Mohsen Ghali, Keita Ohtani, Yuzo Ohno and Hideo Ohno | | | As quantum information and communication experiments grow in sophistication, the need for efficient sources of entangled photons escalates. Using exciton and biexciton emission in GaAs island quantum dots, Ghali et al. demonstrate the electric field-induced generation of entangled photons with high fidelity. | | | 07 Feb | Nat Commun 3:661 doi:10.1038/ncomms1657 (2012) | | | Physical sciences Applied physics | | | Condensed matter Nanotechnology | | | Abstract | Full Text | PDF (858 kB) |
| Rapid microbial response to the presence of an ancient relic in the Antarctic Dry Valleys | | | Grace Tiao, Charles K. Lee, Ian R. McDonald, Donald A. Cowan and S. Craig Cary | | | It is thought that turnover in soil microbiota occurs very slowly in the Antarctic Dry Valleys due to the extreme cold and aridity. Now, Tiao et al. show that a transformation of microbial communities can happen in a matter of years in soils altered by the presence of a mummified seal. | | | 07 Feb | Nat Commun 3:660 doi:10.1038/ncomms1645 (2012) | | Biological sciences Ecology Microbiology
