This study demonstrates that a large class of such processes are most efficiently simulated by quantum mechanical models, thus reducing the complexity required to simulate them using classical models. 27 Mar | Nat Commun 3:762 doi:10.1038/ncomms1761 (2012) Physical sciences  Abstract | Full Text | PDF (488 kB) Past daily light cycle recorded in the strontium/calcium ratios of giant clam shells Yuji Sano, Sayumi Kobayashi, Kotaro Shirai, Naoto Takahata, Katsumi Matsumoto, Tsuyoshi Watanabe, Kohki Sowa and Kenji Iwai A record of the daily light cycle in tropical regions is difficult to extract from biogenic marine carbonates such as shells. Here, the precise analysis of Sr/Ca ratios is shown in a cultivated giant clam shell, revealing variations that reflect the daily light cycle and the potential for future development of a proxy. 27 Mar | Nat Commun 3:761 doi:10.1038/ncomms1763 (2012) Earth sciences Analytical chemistry  Biogeochemistry Oceanography  Abstract | Full Text | PDF (906 kB) | Supplementary Information Poly(ADP-ribose) controls DE-cadherin-dependent stem cell maintenance and oocyte localization Yingbiao Ji and Alexei V. Tulin Drosophila germline stem cells are anchored to their niche via DE-cadherin. In this study, poly(ADP-ribose) is shown to regulate the expression of DE-cadherin via the heterogeneous nuclear ribonucleoprotein, hnRNPA1, and defects in poly(ADP-ribose) catabolism or hnRNPA1 deficiency lead to the loss of germline stem cells. 27 Mar | Nat Commun 3:760 doi:10.1038/ncomms1759 (2012) Biological sciences Cell biology Developmental biology  Abstract | Full Text | PDF (33,122 kB) | Supplementary Information Neural circuits in the brain that are activated when mitigating criminal sentences OPEN Makiko Yamada, Colin F. Camerer, Saori Fujie, Motoichiro Kato, Tetsuya Matsuda, Harumasa Takano, Hiroshi Ito, Tetsuya Suhara and Hidehiko Takahashi Jurors can be influenced by mitigating circumstances when deciding on sentences for committed crimes. Yamada et al. show that feelings of sympathy created by mitigating circumstances activate moral conflict regions of the brain that predict individual differences in the severity of the sentence. 27 Mar | Nat Commun 3:759 doi:10.1038/ncomms1757 (2012) Biological sciences Neuroscience  Abstract | Full Text | PDF (488 kB) | Supplementary Information FAD-dependent lysine-specific demethylase-1 regulates cellular energy expenditure OPEN Shinjiro Hino, Akihisa Sakamoto, Katsuya Nagaoka, Kotaro Anan, Yuqing Wang, Shinya Mimasu, Takashi Umehara, Shigeyuki Yokoyama, Ken-ichiro Kosai and Mitsuyoshi Nakao Lysine-specific demethylase 1 (LSD1) removes methyl groups from mono-methylated and dimethylated lysine 4 of histone H3 and represses transcription. In this study, a role for LSD1 in the regulation of genes involved in energy expenditure in adipocytes is reported in vitro and in mice fed on a high-fat diet. 27 Mar | Nat Commun 3:758 doi:10.1038/ncomms1755 (2012) Biological sciences Cell biology  Medical research  Molecular biology Abstract | Full Text | PDF (1,070 kB) | Supplementary Information Ultra-low carrier concentration and surface-dominant transport in antimony-doped Bi2Se3 topological insulator nanoribbons Seung Sae Hong, Judy J. Cha, Desheng Kong and Yi Cui The singular properties of topological insulators are defined by the topological nature of their metallic surface states. This study shows that by doping Bi2Se3 nanoribbons with antimony, the transport properties of these surface states are measurable and can be distinguished from the contributions due to the bulk of the samples. 27 Mar | Nat Commun 3:757 doi:10.1038/ncomms1771 (2012) Physical sciences Condensed matter  Materials science Nanotechnology Abstract | Full Text | PDF (661 kB) | Supplementary Information Dark acoustic metamaterials as super absorbers for low-frequency sound Jun Mei, Guancong Ma, Min Yang, Zhiyu Yang, Weijia Wen and Ping Sheng Metamaterials can be used to alter the transmission of light or sound, with their tailored structures permitting control over their optical or acoustic properties. Mei et al. present a thin-film acoustic metamaterial that provides efficient absorption of sound over a broad range of wavelengths. 27 Mar | Nat Commun 3:756 doi:10.1038/ncomms1758 (2012) Physical sciences Applied physics  Materials science Abstract | Full Text | PDF (577 kB) | Supplementary Information Annexin A2 binds to endosomes following organelle destabilization by particulate wear debris Brian Scharf, Cristina C. Clement, Xiao-Xuan Wu, Kateryna Morozova, Diego Zanolini, Antonia Follenzi, Jorge N. Larocca, Kalle Levon, Fayyaz S. Sutterwala, Jacob Rand, Neil Cobelli, Ed Purdue, Katherine A. Hajjar and Laura Santambrogio Endosomes contain hydrolytic enzymes, and recent reports have suggested that the endosomal membrane can be damaged by wear particles, resulting in the release of their contents and an inflammatory response. In this study, a role for annexin II in the repair of the damaged endosome membrane is reported. 27 Mar | Nat Commun 3:755 doi:10.1038/ncomms1754 (2012) Biological sciences Cell biology  Immunology Medical research Abstract | Full Text | PDF (1,785 kB) | Supplementary Information Casein kinase 2 reverses tail-independent inactivation of kinesin-1 Jing Xu, Babu J. N. Reddy, Preetha Anand, Zhanyong Shu, Silvia Cermelli, Michelle K. Mattson, Suvranta K. Tripathy, Matthew T. Hoss, Nikita S. James, Stephen J. King, Lan Huang, Lee Bardwell and Steven P. Gross Kinesin-1 is a motor protein that transports cargo along microtubules and defects in this process can result in neurodegeneration. In this study, a role for casein kinase 2 in regulating the activity of Kinesin-2 is reported, suggesting that signalling molecules can modulate this transport process. 27 Mar | Nat Commun 3:754 doi:10.1038/ncomms1760 (2012) Biological sciences Biochemistry  Biophysics  Abstract | Full Text | PDF (1,336 kB) | Supplementary Information   Nature Communications JOBS of the week Postdoctoral position in Developmental biology laboratory Medical University of South Carolina Instructor of Biological Sciences Northwestern State University Long-term Marine Ecological Research University of Stockholm Postdoctoral Position in Neuroscience Cold Spring Harbor Laboratory (CSHL) Scientific Programmer TAJ Technologies Inc Postdoctoral fellow - Cancer Metastasis University of Saskatchewan W3-Professors in Funktionelle Genomik Martin-Luther-Universitat University Lectureship University of Cambridge Department Head of Pharmacology University of Minnesota Medical School Professorial / Senior Fellow Positions The University of Manchester, GlaxoSmithKline and AstraZeneca More Science jobs from Nature Communications EVENT Microbial Stress Responses: from Molecules to Systems 10.-13.05.12 Belgirate, Italy More science events from     Natureevents is a fully searchable, multi-disciplinary database designed to maximise exposure for events organisers.
