Bland-Hawthorn, S.C. Ellis, S.G. Leon-Saval, R. Haynes, M.M. Roth, H.-G. Löhmannsröben, A.J. Horton, J.-G. Cuby, T.A. Birks, J.S. Lawrence, P. Gillingham, S.D. Ryder and C. Trinh The night sky viewed from Earth is very bright at infrared wavelengths due to atmospheric emission, making land-based astronomy difficult in this spectral region. Here, a photonic filter is demonstrated to suppress this unwanted light, opening new paths to infrared astronomy with current and future telescopes. 06 Dec | Nat Commun 2:581 doi:10.1038/ncomms1584 (2011) Physical sciences  Applied physics Astronomy  Atmospheric science  Optical physics Abstract | Full Text | PDF (917 kB) Spin waves and magnetic exchange interactions in insulating Rb0.89Fe1.58Se2 Miaoyin Wang, Chen Fang, Dao-Xin Yao, GuoTai Tan, Leland W. Harriger, Yu Song, Tucker Netherton, Chenglin Zhang, Meng Wang, Matthew B. Stone, Wei Tian, Jiangping Hu and Pengcheng Dai Unlike the other iron-based superconductors, the parent compounds of the alkaline iron selenide superconductors are insulators. Dai and colleagues examine the spin-wave excitations in these materials and uncover evidence for a common magnetic origin for all iron-based superconductors. 06 Dec | Nat Commun 2:580 doi:10.1038/ncomms1573 (2011) Physical sciences Condensed matter  Materials science  Abstract | Full Text | PDF (1,237 kB) | Supplementary Information Plasmon resonance enhanced multicolour photodetection by graphene Yuan Liu, Rui Cheng, Lei Liao, Hailong Zhou, Jingwei Bai, Gang Liu, Lixin Liu, Yu Huang and Xiangfeng Duan Among the wide range of potential applications of graphene, photodetection is believed to be among the most promising. By combining graphene with plasmonic nanostructures, Duan and colleagues observe dramatic improvements in the efficiency and spectral sensitivity of graphene-based photodetectors. 06 Dec | Nat Commun 2:579 doi:10.1038/ncomms1589 (2011) Physical sciences Applied physics  Materials science Nanotechnology Abstract | Full Text | PDF (1,004 kB) | Supplementary Information Low-concentration mechanical biosensor based on a photonic crystal nanowire array Yuerui Lu, Songming Peng, Dan Luo and Amit Lal Nanomechanical resonators are attractive as ultra-low concentration sensors of biomolecules, as their small scale allows for sensitive mass detection. Here, using a nanowire array as part of a photonic crystal, such a device is presented for light trapping, absorption and low-concentration sensing. 06 Dec | Nat Commun 2:578 doi:10.1038/ncomms1587 (2011) Physical sciences Applied physics  Bioengineering Biotechnology  Nanotechnology Abstract | Full Text | PDF (926 kB) | Supplementary Information Binding of herpes simplex virus glycoprotein D to nectin-1 exploits host cell adhesion Na Zhang, Jinghua Yan, Guangwen Lu, Zhengfei Guo, Zheng Fan, Jiawei Wang, Yi Shi, Jianxun Qi and George F Gao Herpesvirus glycoprotein D binds to nectin 1 and the herpes virus entry mediator protein on the surface of host cells. In this study, Zhang et al. report the crystal structure of glycoprotein D in complex with the immunoglobulin-like domains of nectin 1, which suggests that binding of glycoprotein D to nectin 1 prevents nectin 1 dimerization. 06 Dec | Nat Commun 2:577 doi:10.1038/ncomms1571 (2011) Biological sciences Microbiology  Molecular biology Virology Abstract | Full Text | PDF (1,731 kB) Activin enhances skin tumourigenesis and malignant progression by inducing a pro-tumourigenic immune cell response OPEN Maria Antsiferova, Marcel Huber, Michael Meyer, Aleksandra Piwko-Czuchra, Tamara Ramadan, Amanda S. MacLeod, Wendy L. Havran, Reinhard Dummer, Daniel Hohl and Sabine Werner Activin is known to have a role in wound healing, but its role in skin cancer is unknown. Antsiferova et al. show that activin is elevated in human skin tumours, and by modulating epidermal immune cells, exacerbates tumour progression in a mouse model of skin cancer. 06 Dec | Nat Commun 2:576 doi:10.1038/ncomms1585 (2011) Biological sciences Cancer  Cell biology Immunology  Medical research Abstract | Full Text | PDF (1,422 kB) | Supplementary Information Gate-tuned normal and superconducting transport at the surface of a topological insulator OPEN Benjamin Sacépé, Jeroen B. Oostinga, Jian Li, Alberto Ubaldini, Nuno J.G. Couto, Enrico Giannini and Alberto F. Morpurgo Topological insulators are a unique class of materials characterized by exotic metallic states at their surface, while remaining insulated in the bulk. Sacépé et al. show how to manipulate normal and superconducting electronic transport at the surface of the topological insulator Bi2Se3, by tuning a gate-voltage to vary the electronic density. 06 Dec | Nat Commun 2:575 doi:10.1038/ncomms1586 (2011) Physical sciences Condensed matter  Materials science Nanotechnology Abstract | Full Text | PDF (899 kB) | Supplementary Information Band structure engineering in (Bi1–xSbx)2Te3 ternary topological insulators Jinsong Zhang, Cui-Zu Chang, Zuocheng Zhang, Jing Wen, Xiao Feng, Kang Li, Minhao Liu, Ke He, Lili Wang, Xi Chen, Qi-Kun Xue, Xucun Ma and Yayu Wang The unique band structure of topological insulators gives rise to insulating bulk and unusual metallic surface properties. By tuning the content of Sb in the ternary compound (Bi1–xSbx)2Te3, Wang and collaborators show it is possible to control the precise features of the band structure in a continuous fashion. 06 Dec | Nat Commun 2:574 doi:10.1038/ncomms1588 (2011) Physical sciences Applied physics  Condensed matter Materials science  Nanotechnology Abstract | Full Text | PDF (748 kB) | Supplementary Information The evolution of sensory divergence in the context of limited gene flow in the bumblebee bat OPEN Sébastien J. Puechmaille, Meriadeg Ar Gouilh, Piyathip Piyapan, Medhi Yokubol, Khin Mie Mie, Paul J. Bates, Chutamas Satasook, Tin Nwe, Si Si Hla Bu, Iain J. Mackie, Eric J. Petit and Emma C. Teeling Populations of the same species living in different habitats can differ in sensory traits driving speciation, but it is not known if this variation limits gene flow. Here, a genetic and acoustic study of the bumblebee bat suggests that geographic distance, instead of echolocation divergence, limits gene flow. 06 Dec | Nat Commun 2:573 doi:10.1038/ncomms1582 (2011) Biological sciences Ecology  Evolution Genetics  Abstract | Full Text | PDF (686 kB) | Supplementary Information Magnetic resonance force microscopy of paramagnetic electron spins at millikelvin temperatures A. Vinante, G. Wijts, O. Usenko, L. Schinkelshoek and T.H. Oosterkamp Magnetic resonance force microscopy is a scanning probe technique capable of detecting and imaging electron spins. Vinante et al. bring the operating temperature of this method into the millikelvin temperature regime, revealing spin diffusion phenomena that were hitherto inaccessible. 06 Dec | Nat Commun 2:572 doi:10.1038/ncomms1581 (2011) Physical sciences Condensed matter  Nanotechnology  Abstract | Full Text | PDF (480 kB) | Supplementary Information Graphene chiral liquid crystals and macroscopic assembled fibres OPEN Zhen Xu and Chao Gao Chiral liquid crystals of two-dimensional colloids have not been extensively investigated. Xu and Gao show that graphene oxide can form chiral liquid crystals, and demonstrate that they can be spun into macroscopic fibres, and that subsequent chemical reduction provides graphene fibres with high conductivity. 06 Dec | Nat Commun 2:571 doi:10.1038/ncomms1583 (2011) Chemical sciences Applied physics  Materials science Nanotechnology Abstract | Full Text | PDF (2,087 kB) | Supplementary Information Observation of an anomalous decoherence effect in a quantum bath at room temperature OPEN Pu Huang, Xi Kong, Nan Zhao, Fazhan Shi, Pengfei Wang, Xing Rong, Ren-Bao Liu and Jiangfeng Du Quantum objects are subject to decoherence effects due to the surrounding environment. This study demonstrates experimentally a counterintuitive example of anomalous decoherence, in which electron spins residing at nitrogen vacancy centres in diamond display longer coherence times under stronger noises. 06 Dec | Nat Commun 2:570 doi:10.1038/ncomms1579 (2011) Physical sciences Applied physics  Condensed matter Nanotechnology  Abstract | Full Text | PDF (786 kB) | Supplementary Information Reinforcement learning in professional basketball players OPEN Tal Neiman and Yonatan Loewenstein Reinforcement learning quantifies the change in behaviour in response to past experience. Using field goal attempt data from basketball, Neiman and Loewenstein demonstrate that even one failed or made attempt has an impact on subsequent attempts, showing that players overgeneralize from their most recent actions. 06 Dec | Nat Commun 2:569 doi:10.1038/ncomms1580 (2011) Biological sciences Neuroscience Abstract | Full Text | PDF (381 kB) | Supplementary Information   Nature Communications JOBS of the week protein biochemistry, vascular biology, or immunology.
