In doing so, it highlights how our understanding of the pluripotent state has evolved over almost 60 years.

Goto, Eiichi Tajika, Ryuji Tada, Kazuhisa Goto, Shinji Yamamoto, Naohiko Ohkouchi, Nanako O. Ogawa and Teruyuki Maruoka The Early Palaeoproterozoic saw glaciations and a rise in atmospheric oxygen, but the link between these two changes is poorly understood. Here, osmium isotope records from sedimentary rocks indicate synchronicity between an episode of increasing oxygen and a glacial transition. 11 Oct | Nat Commun 2:502 doi:10.1038/ncomms1507 (2011) Earth sciences Biogeochemistry  Geology and geophysics  Abstract | Full Text | PDF (439 kB) | Supplementary Information The ubiquitin ligase HACE1 regulates Golgi membrane dynamics during the cell cycle Danming Tang, Yi Xiang, Stefano De Renzis, Jochen Rink, Gen Zheng, Marino Zerial and Yanzhuang Wang The Golgi membrane is fragmented during mitosis and is subsequently fused following cell division and this process is known to be controlled by ubiquitination. In this study, the ubiquitin ligase HACE1 is shown to be targeted to the Golgi membrane and is required for fusion after the completion of mitosis. 11 Oct | Nat Commun 2:501 doi:10.1038/ncomms1509 (2011) Biological sciences Biochemistry  Cell biology  Abstract | Full Text | PDF (1,641 kB) | Supplementary Information Travelling and splitting of a wave of hedgehog expression involved in spider-head segmentation OPEN Masaki Kanayama, Yasuko Akiyama-Oda, Osamu Nishimura, Hiroshi Tarui, Kiyokazu Agata and Hiroki Oda During development, waves of gene expression are required for segmentation of the body axis. In this study, repeated splitting of a wave of hedgehog gene expression is shown during segmentation of the spider Achaearanea tepidariorum. 11 Oct | Nat Commun 2:500 doi:10.1038/ncomms1510 (2011) Biological sciences Developmental biology  Zoology Abstract | Full Text | PDF (1,495 kB) | Supplementary Information Pericytes resident in postnatal skeletal muscle differentiate into muscle fibres and generate satellite cells A. Dellavalle, G. Maroli, D. Covarello, E. Azzoni, A. Innocenzi, L. Perani, S. Antonini, R. Sambasivan, S. Brunelli, S. Tajbakhsh and G. Cossu The fusion of satellite cells to muscle fibres during adult life is required for both muscle growth and regeneration but it is unknown whether non-muscle cells contribute to this process. Now, Dellavalle and colleagues show that pericytes, cells associated with the vasculature can contribute to both growth and regeneration of muscle fibres. 11 Oct | Nat Commun 2:499 doi:10.1038/ncomms1508 (2011) Biological sciences Cell biology  Developmental biology  Abstract | Full Text | PDF (2,419 kB) | Supplementary Information NMDA receptor activation requires remodelling of intersubunit contacts within ligand-binding heterodimers William F. Borschel, Swetha E. Murthy, Eileen M. Kasperek and Gabriela K. Popescu In non-NMDA glutamate receptors, intersubunit contacts within agonist binding domains affect functional desensitization. Now, NMDA receptor activation, but not desensitization, is shown to involve rearrangements at the heterodimer interface, suggesting that the intersubunit contacts of NMDA and non-NMDA receptors may have distinct functional roles. 11 Oct | Nat Commun 2:498 doi:10.1038/ncomms1512 (2011) Biological sciences Biochemistry  Biophysics Neuroscience  Abstract | Full Text | PDF (2,381 kB) | Supplementary Information A mitochondria-targeted inhibitor of cytochrome c peroxidase mitigates radiation-induced death Jeffrey Atkinson, Alexandr A. Kapralov, Naveena Yanamala, Yulia Y. Tyurina, Andrew A. Amoscato, Linda Pearce, Jim Peterson, Zhentai Huang, Jianfei Jiang, Alejandro K. Samhan-Arias, Akihiro Maeda, Weihong Feng, Karla Wasserloos, Natalia A. Belikova, Vladimir A. Tyurin, Hong Wang, Jackie Fletcher, Yongsheng Wang, Irina I. Vlasova, Judith Klein-Seetharaman, Detcho A. Stoyanovsky, Hülya Bayîr, Bruce R. Pitt, Michael W. Epperly, Joel S. Greenberger and Valerian E. Kagan Radiomitigating compounds could be used to protect against ionizing radiation. In this study, mitochondria-targeted oleic and stearic acid derivatives are shown to inhibit pro-apoptotic oxidative events, prevent cell death, and protect mice against lethal doses of radiation. 11 Oct | Nat Commun 2:497 doi:10.1038/ncomms1499 (2011) Chemical sciences Biochemistry  Chemical biology Medicinal chemistry Abstract | Full Text | PDF (1,163 kB) | Supplementary Information Electrosensory ampullary organs are derived from lateral line placodes in bony fishes Melinda S. Modrell, William E. Bemis, R. Glenn Northcutt, Marcus C. Davis and Clare V.H. Baker Ampullary organs are involved in electroreception, but whether these are derived from placodes, thickened ectoderm, is unclear. In this study, the ampullary organs of the primitive ray-finned fish, Polyodon spathula, are shown to develop from lateral line placodes, suggesting that this is the ancestral state in bony fishes. 11 Oct | Nat Commun 2:496 doi:10.1038/ncomms1502 (2011) Biological sciences Developmental biology  Evolution Molecular biology  Neuroscience Abstract | Full Text | PDF (2,615 kB) Selective fluorescent probes for live-cell monitoring of sulphide Yong Qian, Jason Karpus, Omer Kabil, Shu-Yu Zhang, Hai-Liang Zhu, Ruma Banerjee, Jing Zhao and Chuan He Molecular probes that can detect aqueous sulphides could help to elucidate their roles in biological signalling. Qian et al. develop two sulphide-selective fluorescent probes and demonstrate their ability to image free sulphide in living cells. 11 Oct | Nat Commun 2:495 doi:10.1038/ncomms1506 (2011) Chemical sciences Chemical biology  Organic chemistry  Abstract | Full Text | PDF (925 kB) | Supplementary Information Control of electronic conduction at an oxide heterointerface using surface polar adsorbates Yanwu Xie, Yasuyuki Hikita, Christopher Bell and Harold Y. Hwang The interfaces between complex oxides can play host to a range of interesting electronic phenomena. Xie et al. demonstrate that the electronic properties at the LaAlO3/SrTiO3 interface can be tuned upon application of common polar solvents such as acetone, ethanol and water. 11 Oct | Nat Commun 2:494 doi:10.1038/ncomms1501 (2011) Physical sciences Applied physics  Condensed matter Nanotechnology  Abstract | Full Text | PDF (1,464 kB) Single-molecule fluorescence spectroscopy maps the folding landscape of a large protein Menahem Pirchi, Guy Ziv, Inbal Riven, Sharona Sedghani Cohen, Nir Zohar, Yoav Barak and Gilad Haran The folding of multidomain proteins can involve metastable intermediate states. Here, a single-molecule FRET based method is developed and used to identify six metastable states in the folding landscape of the three-domain protein adenylate kinase. 11 Oct | Nat Commun 2:493 doi:10.1038/ncomms1504 (2011) Biological sciences Biophysics  Abstract | Full Text | PDF (1,034 kB) | Supplementary Information Bottom-up synthesis of finite models of helical (n,m)-single-wall carbon nanotubes Shunpei Hitosugi, Waka Nakanishi, Takashi Yamasaki and Hiroyuki Isobe Hoop-shaped aromatic hydrocarbons can be considered as finite models of single-wall carbon nanotubes. Hitosugi et al. describe the bottom-up synthesis of a macrocyclic tetramer of chrysene, and show that its persistent rotational isomers are finite models of chiral nanotubes. 11 Oct | Nat Commun 2:492 doi:10.1038/ncomms1505 (2011) Chemical sciences Materials science  Nanotechnology Organic chemistry  Abstract | Full Text | PDF (437 kB) | Supplementary Information   Nature Communications JOBS of the week Research Fellow in Health Service Research Peninsula College of Medicine and Dentistry Exeter, GB Chair Professorship University of Colorado Boulder, US Assistant / Associate Professor of Biochemistry University of Missouri Columbia, US Faculty Positions Memorial Sloan-Kettering Cancer Center New York, US Junior Research Groups University of Würzburg Würzburg, DE Professorship in Earth and Environmental Science University of Pennsylvania Philadelphia, US Tenure-Track Position in Cell Biology McGill University Quebec City, CA W3-Professur fur Vaskulare Neurologie Universitat Heidelberg Heidelberg, DE Postdoctoral Opportunity International Agency for Research on Cancer Lyon, FR Science Portfolio Adviser Wellcome Trust London, GB More Science jobs from Nature Communications EVENT 14th World Congress on Controversies in Obstetrics, Gynecology & Infertility (COGI™) 17.-20.11.11 Paris, France More science events from   Advertisement Take a look at this article that recently appeared in Heredity: An autosomal locus controls sex reversal in interspecific XY hybrids of the medaka fishes FREE M Kato, Y Takehana, Y Fukuda, K Naruse, M Sakaizumi et al Heredity doi:10.1038/hdy.2011.38   Natureevents is a fully searchable, multi-disciplinary database designed to maximise exposure for events organisers.
