Description: From determining the optical properties of simple molecular crystals to establishing the preferred handedness in highly complex vertebrates, molecular chirality profoundly influences the structural, mechanical and optical properties of both synthetic and biological matter on macroscopic length scales. In soft materials such as amphiphilic lipids and liquid crystals, the competition between local chiral interactions and global constraints imposed by the geometry of the self-assembled structures leads to frustration and the assembly of unique materials. An example of particular interest is smectic liquid crystals, where the two-dimensional layered geometry cannot support twist and chirality is consequently expelled to the edges in a manner analogous to the expulsion of a magnetic field from superconductors. Here we demonstrate a consequence of this geometric frustration that leads to a new design principle for the assembly of chiral molecules. Using a model system of colloidal membranes, we show that molecular chirality can control the interfacial tension, an important property of multi-component mixtures. This suggests an analogy between chiral twist, which is expelled to the edges of two-dimensional membranes, and amphiphilic surfactants, which are expelled to oil-water interfaces. As with surfactants, chiral control of interfacial tension drives the formation of many polymorphic assemblages such as twisted ribbons with linear and circular topologies, starfish membranes, and double and triple helices. Tuning molecular chirality in situ allows dynamical control of line tension, which powers polymorphic transitions between various chiral structures. These findings outline a general strategy for the assembly of reconfigurable chiral materials that can easily be moved, stretched, attached to one another and transformed between multiple conformational states, thus allowing precise assembly and nanosculpting of highly dynamical and designable materials with complex topologies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibaud, Thomas -- Barry, Edward -- Zakhary, Mark J -- Henglin, Mir -- Ward, Andrew -- Yang, Yasheng -- Berciu, Cristina -- Oldenbourg, Rudolf -- Hagan, Michael F -- Nicastro, Daniela -- Meyer, Robert B -- Dogic, Zvonimir -- R01 EB002583/EB/NIBIB NIH HHS/ -- England -- Nature. 2012 Jan 4;481(7381):348-51. doi: 10.1038/nature10769.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Martin Fisher School of Physics, Brandeis University, 415 South Street, Waltham, Massachusetts 02454, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22217941" target="_blank"〉PubMed〈/a〉

Description: Dislocations represent one of the most fascinating and fundamental concepts in materials science. Most importantly, dislocations are the main carriers of plastic deformation in crystalline materials. Furthermore, they can strongly affect the local electronic and optical properties of semiconductors and ionic crystals. In materials with small dimensions, they experience extensive image forces, which attract them to the surface to release strain energy. However, in layered crystals such as graphite, dislocation movement is mainly restricted to the basal plane. Thus, the dislocations cannot escape, enabling their confinement in crystals as thin as only two monolayers. To explore the nature of dislocations under such extreme boundary conditions, the material of choice is bilayer graphene, the thinnest possible quasi-two-dimensional crystal in which such linear defects can be confined. Homogeneous and robust graphene membranes derived from high-quality epitaxial graphene on silicon carbide provide an ideal platform for their investigation. Here we report the direct observation of basal-plane dislocations in freestanding bilayer graphene using transmission electron microscopy and their detailed investigation by diffraction contrast analysis and atomistic simulations. Our investigation reveals two striking size effects. First, the absence of stacking-fault energy, a unique property of bilayer graphene, leads to a characteristic dislocation pattern that corresponds to an alternating AB B[Symbol: see text]AC change of the stacking order. Second, our experiments in combination with atomistic simulations reveal a pronounced buckling of the bilayer graphene membrane that results directly from accommodation of strain. In fact, the buckling changes the strain state of the bilayer graphene and is of key importance for its electronic properties. Our findings will contribute to the understanding of dislocations and of their role in the structural, mechanical and electronic properties of bilayer and few-layer graphene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butz, Benjamin -- Dolle, Christian -- Niekiel, Florian -- Weber, Konstantin -- Waldmann, Daniel -- Weber, Heiko B -- Meyer, Bernd -- Spiecker, Erdmann -- England -- Nature. 2014 Jan 23;505(7484):533-7. doi: 10.1038/nature12780.

Description: West Africa is currently witnessing the most extensive Ebola virus (EBOV) outbreak so far recorded. Until now, there have been 27,013 reported cases and 11,134 deaths. The origin of the virus is thought to have been a zoonotic transmission from a bat to a two-year-old boy in December 2013 (ref. 2). From this index case the virus was spread by human-to-human contact throughout Guinea, Sierra Leone and Liberia. However, the origin of the particular virus in each country and time of transmission is not known and currently relies on epidemiological analysis, which may be unreliable owing to the difficulties of obtaining patient information. Here we trace the genetic evolution of EBOV in the current outbreak that has resulted in multiple lineages. Deep sequencing of 179 patient samples processed by the European Mobile Laboratory, the first diagnostics unit to be deployed to the epicentre of the outbreak in Guinea, reveals an epidemiological and evolutionary history of the epidemic from March 2014 to January 2015. Analysis of EBOV genome evolution has also benefited from a similar sequencing effort of patient samples from Sierra Leone. Our results confirm that the EBOV from Guinea moved into Sierra Leone, most likely in April or early May. The viruses of the Guinea/Sierra Leone lineage mixed around June/July 2014. Viral sequences covering August, September and October 2014 indicate that this lineage evolved independently within Guinea. These data can be used in conjunction with epidemiological information to test retrospectively the effectiveness of control measures, and provides an unprecedented window into the evolution of an ongoing viral haemorrhagic fever outbreak.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carroll, Miles W -- Matthews, David A -- Hiscox, Julian A -- Elmore, Michael J -- Pollakis, Georgios -- Rambaut, Andrew -- Hewson, Roger -- Garcia-Dorival, Isabel -- Bore, Joseph Akoi -- Koundouno, Raymond -- Abdellati, Said -- Afrough, Babak -- Aiyepada, John -- Akhilomen, Patience -- Asogun, Danny -- Atkinson, Barry -- Badusche, Marlis -- Bah, Amadou -- Bate, Simon -- Baumann, Jan -- Becker, Dirk -- Becker-Ziaja, Beate -- Bocquin, Anne -- Borremans, Benny -- Bosworth, Andrew -- Boettcher, Jan Peter -- Cannas, Angela -- Carletti, Fabrizio -- Castilletti, Concetta -- Clark, Simon -- Colavita, Francesca -- Diederich, Sandra -- Donatus, Adomeh -- Duraffour, Sophie -- Ehichioya, Deborah -- Ellerbrok, Heinz -- Fernandez-Garcia, Maria Dolores -- Fizet, Alexandra -- Fleischmann, Erna -- Gryseels, Sophie -- Hermelink, Antje -- Hinzmann, Julia -- Hopf-Guevara, Ute -- Ighodalo, Yemisi -- Jameson, Lisa -- Kelterbaum, Anne -- Kis, Zoltan -- Kloth, Stefan -- Kohl, Claudia -- Korva, Misa -- Kraus, Annette -- Kuisma, Eeva -- Kurth, Andreas -- Liedigk, Britta -- Logue, Christopher H -- Ludtke, Anja -- Maes, Piet -- McCowen, James -- Mely, Stephane -- Mertens, Marc -- Meschi, Silvia -- Meyer, Benjamin -- Michel, Janine -- Molkenthin, Peter -- Munoz-Fontela, Cesar -- Muth, Doreen -- Newman, Edmund N C -- Ngabo, Didier -- Oestereich, Lisa -- Okosun, Jennifer -- Olokor, Thomas -- Omiunu, Racheal -- Omomoh, Emmanuel -- Pallasch, Elisa -- Palyi, Bernadett -- Portmann, Jasmine -- Pottage, Thomas -- Pratt, Catherine -- Priesnitz, Simone -- Quartu, Serena -- Rappe, Julie -- Repits, Johanna -- Richter, Martin -- Rudolf, Martin -- Sachse, Andreas -- Schmidt, Kristina Maria -- Schudt, Gordian -- Strecker, Thomas -- Thom, Ruth -- Thomas, Stephen -- Tobin, Ekaete -- Tolley, Howard -- Trautner, Jochen -- Vermoesen, Tine -- Vitoriano, Ines -- Wagner, Matthias -- Wolff, Svenja -- Yue, Constanze -- Capobianchi, Maria Rosaria -- Kretschmer, Birte -- Hall, Yper -- Kenny, John G -- Rickett, Natasha Y -- Dudas, Gytis -- Coltart, Cordelia E M -- Kerber, Romy -- Steer, Damien -- Wright, Callum -- Senyah, Francis -- Keita, Sakoba -- Drury, Patrick -- Diallo, Boubacar -- de Clerck, Hilde -- Van Herp, Michel -- Sprecher, Armand -- Traore, Alexis -- Diakite, Mandiou -- Konde, Mandy Kader -- Koivogui, Lamine -- Magassouba, N'Faly -- Avsic-Zupanc, Tatjana -- Nitsche, Andreas -- Strasser, Marc -- Ippolito, Giuseppe -- Becker, Stephan -- Stoecker, Kilian -- Gabriel, Martin -- Raoul, Herve -- Di Caro, Antonino -- Wolfel, Roman -- Formenty, Pierre -- Gunther, Stephan -- 095831/Wellcome Trust/United Kingdom -- England -- Nature. 2015 Aug 6;524(7563):97-101. doi: 10.1038/nature14594.

Description: In Hungary, wind erosion is one of the most serious natural hazards. Spatial and temporal variation in the factors that determine the location and intensity of wind erosion damage are not well known, nor are the regional and local sensitivities to erosion. Because of methodological challenges, no multi-factor, regional wind erosion sensitivity map is available for Hungary. The aim of this study was to develop a method to estimate the regional differences in wind erosion sensitivity and exposure in Hungary. Wind erosion sensitivity was modelled using the key factors of soil sensitivity, vegetation cover and wind erodibility as proxies. These factors were first estimated separately by factor sensitivity maps and later combined by fuzzy logic into a regional-scale wind erosion sensitivity map. Large areas were evaluated by using publicly available data sets of remotely sensed vegetation information, soil maps and meteorological data on wind speed. The resulting estimates were verified by field studies and examining the economic losses from wind erosion as compensated by the state insurance company. The spatial resolution of the resulting sensitivity map is suitable for regional applications, as identifying sensitive areas is the foundation for diverse land development control measures and implementing management activities.

Description: The Olympos-Ossa-Pelion (OOP) ranges, in NW Aegean, encompass Greece highest summit and are located near the extremity of the North Anatolian Fault (NAF). Structural and thermochronological data gathered in the OOP ranges show that the main exhumation of metamorphic nappes occurred in the Eocene, at ca. 43–39 Ma. This early exhumation, associated with ductile, then brittle-ductile normal faulting with northeastward transport, is nearly coeval with orogenic shortening in the close area. Cooling rates, and likely exhumation, have been low between ~40 Ma and ~20 Ma. 40Ar/39Ar crystallization ages (between 20 and 15 Ma) appears related to brittle-ductile normal faulting and likely associated with the onset of Aegean back-arc extension. The dating of a diabase dyke, and the geometry of associated brittle jointing, of onshore and offshore active normal faults imply a shift in extension direction after 4 Ma. Such a shift is probably related the propagation of the NAF in northern Aegean known to have occurred around 5 Ma.
