White, Eric D. Głowacki, Tsuyoshi Sekitani, Takao Someya, Niyazi Serdar Sariciftci and Siegfried Bauer Organic solar cells are promising for technological applications, as they are lightweight and mechanically robust. This study presents flexible organic solar cells that are less than 2 μm thick, have very low specific weight and maintain their photovoltaic performance under repeated mechanical deformation. 03 Apr | Nat Commun 3:770 doi:10.1038/ncomms1772 (2012) Physical sciences Materials science Nanotechnology  Physical chemistry  Abstract | Full Text | PDF (752 kB) | Supplementary Information Drosophila follicle stem cells are regulated by proliferation and niche adhesion as well as mitochondria and ROS Zhu A. Wang, Jianhua Huang and Daniel Kalderon Stem cells are thought to be tethered in their niche via adhesion molecules and the inhibition of cell differentiation. Here, the authors screened for genes required for maintaining Drosophila ovarian follicle stem cells and found their function to depend on cell proliferation, mitochondrial function and niche adhesion. 03 Apr | Nat Commun 3:769 doi:10.1038/ncomms1765 (2012) Biological sciences Cell biology  Developmental biology  Abstract | Full Text | PDF (1,038 kB) | Supplementary Information Growth of non-phototrophic microorganisms using solar energy through mineral photocatalysis Anhuai Lu, Yan Li, Song Jin, Xin Wang, Xiao-Lei Wu, Cuiping Zeng, Yan Li, Hongrui Ding, Ruixia Hao, Ming Lv, Changqiu Wang, Yueqin Tang and Hailiang Dong Microbial metabolism is usually considered to be phototrophic or chemotrophic. By showing that light-induced photoelectrons from metal oxide and metal sulfides can stimulate the growth of chemoautotrophic and heterotrophic bacteria, this study indicates that light may be involved in non-phototrophic microbial activity. 03 Apr | Nat Commun 3:768 doi:10.1038/ncomms1768 (2012) Biological sciences Microbiology Abstract | Full Text | PDF (609 kB) | Supplementary Information BCR-signalling synergizes with TLR-signalling for induction of AID and immunoglobulin class-switching through the non-canonical NF-κB pathway OPEN Egest J. Pone, Jinsong Zhang, Thach Mai, Clayton A. White, Guideng Li, John K. Sakakura, Pina J. Patel, Ahmed Al-Qahtani, Hong Zan, Zhenming Xu and Paolo Casali Class switch recombination diversifies antibody effector functions and requires expression of activation-induced cytidine deaminase (AID). In this study, ligation of the B-cell receptor and Toll-like receptors synergize to induce non-canonical NF-κB activation, AID expression and class switching recombination. 03 Apr | Nat Commun 3:767 doi:10.1038/ncomms1769 (2012) Biological sciences Cell biology Immunology  Molecular biology Abstract | Full Text | PDF (1,993 kB) | Supplementary Information The self-interaction of native TDP-43 C terminus inhibits its degradation and contributes to early proteinopathies I.-Fan Wang, Hsiang-Yu Chang, Shin-Chen Hou, Gunn-Guang Liou, Tzong-Der Way and C.-K. James Shen The C terminus of TAR DNA-binding protein 43 (TDP-43) forms aggregates that are a feature of some neurodegenerative diseases. In this study, Chang et al. show that C terminus of TDP-43 interacts with itself, altering its cellular localisation and the splicing function of the protein. 03 Apr | Nat Commun 3:766 doi:10.1038/ncomms1766 (2012) Biological sciences Cell biology  Molecular biology  Abstract | Full Text | PDF (1,399 kB) | Supplementary Information Demonstration of a stable ultrafast laser based on a nonlinear microcavity OPEN M. Peccianti, A. Pasquazi, Y. Park, B.E. Little, S.T. Chu, D.J. Moss and R. Morandotti Stable, ultrahigh repetition rate optical clocks are critical for applications in high-speed communications, metrology and microchip computing. Peccianti et al. present a mode-locked laser based on an integrated microcavity, with repetition rate exceeding 200 GHz and narrow linewidth pulses. 03 Apr | Nat Commun 3:765 doi:10.1038/ncomms1762 (2012) Physical sciences Applied physics  Nanotechnology Optical physics  Abstract | Full Text | PDF (832 kB) Decreased extra-renal urate excretion is a common cause of hyperuricemia OPEN Kimiyoshi Ichida, Hirotaka Matsuo, Tappei Takada, Akiyoshi Nakayama, Keizo Murakami, Toru Shimizu, Yoshihide Yamanashi, Hiroshi Kasuga, Hiroshi Nakashima, Takahiro Nakamura, Yuzo Takada, Yusuke Kawamura, Hiroki Inoue, Chisa Okada, Yoshitaka Utsumi, Yuki Ikebuchi, Kousei Ito, Makiko Nakamura, Yoshihiko Shinohara, Makoto Hosoyamada, Yutaka Sakurai, Nariyoshi Shinomiya, Tatsuo Hosoya and Hiroshi Suzuki Hyperuricemia, or gout, is thought to arise either from urate overproduction or from decreased renal excretion of urate. Ichida et al. show that the extra-renal excretion of urate also has a role in the pathogenesis of hyperuricemia, and propose a new classification for patients with this disease. 03 Apr | Nat Commun 3:764 doi:10.1038/ncomms1756 (2012) Biological sciences Genetics Medical research Abstract | Full Text | PDF (418 kB) | Supplementary Information   Nature Communications JOBS of the week PhD positions in Population Genetics Vienna Graduate School of Population Genetics Post-Doctoral Research Fellow UNIVERSITY OF SUSSEX Postdoc modeler in Land-Atmosphere Interaction Biodiversity and Climate Research Centre (BiK-F) Discovery Chemistry - Intern H3 Biomedicine Tenure track positions in cell & molecular biology of retinal and optic nerve disease University of Montréal Postdoctoral Fellow in Organic Synthesis and Molecular Imaging Ecole Polytechnique Federale de Lausanne (EPFL, Swiss Federal Institute of Technology) Head of Proteomics Medical Research Council Postdoc in Computational Fungal Genomics Massey University Chair in Veterinary and Comparative Pathology and Director of the Centre for Comparative Pathology The University of Edinburgh Professorship and Division Director: Division of Biosciences Brunel University More Science jobs from Nature Communications EVENT International Symposium on Bioinformatics Research and Applications (ISBRA'12) 21.-23.05.12 TX, US More science events from     Natureevents is a fully searchable, multi-disciplinary database designed to maximise exposure for events organisers.
