Weekly Content Alert 18 October 2011 Featured image: Ettinger et al. show that the extent of midbody release into the extracellular space is greater in stem cells than cancer cells, and can be enhanced upon differentiation.

Using the Pseudomonas syringae hrp system, Wang and colleagues generate AND, NOT and NAND gates, demonstrating the ability to engineer a modular system from biological elements. 18 Oct | Nat Commun 2:508 doi:10.1038/ncomms1516 (2011) Biological sciences Bioengineering  Biotechnology  Abstract | Full Text | PDF (1,163 kB) | Supplementary Information Superconductivity at 5 K in alkali-metal-doped phenanthrene X.F. Wang, R.H. Liu, Z. Gui, Y.L. Xie, Y.J. Yan, J.J. Ying, X.G. Luo and X.H. Chen Intercalating alkali metals into picene—a hydrocarbon with five linearly fused benzene rings—results in superconducting materials. Now, alkali-metal-doped phenanthrene, which consists of three fused benzene rings, is also found to be superconducting, opening up a broader class of organic superconductors. 18 Oct | Nat Commun 2:507 doi:10.1038/ncomms1513 (2011) Physical sciences Materials science Abstract | Full Text | PDF (804 kB) Field-effect reconfigurable nanofluidic ionic diodes Weihua Guan, Rong Fan and Mark A. Reed Nanofluidic diodes are utilized for the rectification of ionic transport, but their rectifying properties cannot be altered after the devices are made. Here, a field-effect reconfigurable nanofluidic diode is reported in which the forward direction and the degree of rectification can be modulated by a gate voltage. 18 Oct | Nat Commun 2:506 doi:10.1038/ncomms1514 (2011) Physical sciences Applied physics  Fluids and plasma physics Nanotechnology Abstract | Full Text | PDF (1,048 kB) | Supplementary Information Quantum interferometric visibility as a witness of general relativistic proper time OPEN Magdalena Zych, Fabio Costa, Igor Pikovski and Časlav Brukner In the theory of general relativity time flows at different rates depending on the space–time geometry. Here, a drop in the visibility of a quantum 'clock' interference in a gravitational potential is predicted, which cannot be explained without the general relativistic notion of time. 18 Oct | Nat Commun 2:505 doi:10.1038/ncomms1498 (2011) Physical sciences Theoretical physics Abstract | Full Text | PDF (642 kB) Behavioural memory reconsolidation of food and fear memories Charlotte R. Flavell, David J. Barber and Jonathan L.C. Lee Memory retrieval followed by extinction training has been shown to erase fear memories. Flavell et al. show that this approach also erases appetitive memories in rats and results from a modification of memory reconsolidation, which could be useful for the treatment of drug addiction. 18 Oct | Nat Commun 2:504 doi:10.1038/ncomms1515 (2011) Biological sciences Neuroscience  Abstract | Full Text | PDF (527 kB) Proliferating versus differentiating stem and cancer cells exhibit distinct midbody-release behaviour OPEN Andreas W. Ettinger, Michaela Wilsch-Bräuninger, Anne-Marie Marzesco, Marc Bickle, Annett Lohmann, Zoltan Maliga, Jana Karbanová, Denis Corbeil, Anthony A. Hyman and Wieland B. Huttner During cell division, a cytoplasmic bridge—the midbody—forms between the nascent daughter cells, but it has been unclear under which conditions this is retained by a daughter cell or released. Now, Ettinger and colleagues show that midbody-release occurs more frequently in stem cells compared with cancer cells. 18 Oct | Nat Commun 2:503 doi:10.1038/ncomms1511 (2011) Biological sciences Cancer  Cell biology  Abstract | Full Text | PDF (1,769 kB) | Supplementary Information   Nature Communications JOBS of the week Senior Researcher - Genomics and Proteomics of Plants CEITEC ‐ Central European Institute of Technology of Masaryk University Brno, CZ Gastroenterology Faculty Position University of Washington Medical Center Seattle, US Postdocotral Research Fellow Level 1 University College Dublin Dublin, IE Research Instructor University of Pittsburgh Pittsburgh, US Postdoctoral position in Cancer Research Prof. Pierre Sonveaux, University of Louvain (UCL) Medical School Brussels, BE Assistant Research Scientist University of Maryland - Center for Environmental Science -CBL Solomons, US Fellowship available in Cancer Research Johns Hopkins University School of Medicine Baltimore, US Professor in Cellular Signaling Network Biology Technical University of Denmark, Department of Systems Biology (CBS) DK PhD Fellowship In RNA Bioinformatics Center for non-coding RNA in Technology and Health Frederiksberg, DK Technische / r Assistent / in - PB D Ref.#D28a Biodiversität und Klima Forschungszentrum Frankfurt Am Main, DE More Science jobs from Nature Communications EVENT Translational Cancer Research for Basic Scientists Workshop 30.10.-04.11.11 MA, US More science events from   Advertisement Nature Cell Biology Focus on Cell cycle and DNA damage The maintenance of genomic integrity requires tight control of the cell division process as well as accurate repair of damaged DNA, and failure in such mechanisms can cause developmental disorders and cancer. In the October issue of Nature Cell Biology, leading scientists highlight and discuss new developments in these areas.
