    A New Lineage of Eukaryotes Illuminates Early Mitochondrial Genome Reduction

    No full text
    The origin of eukaryotic cells represents a key transition in cellular evolution and is closely tied to outstanding questions about mitochondrial endosymbiosis [1, 2]. For example, gene-rich mitochondrial genomes are thought to be indicative of an ancient divergence, but this relies on unexamined assumptions about endosymbiont-to-host gene transfer [3–5]. Here, we characterize Ancoracysta twista, a new predatory flagellate that is not closely related to any known lineage in 201-protein phylogenomic trees and has a unique morphology, including a novel type of extrusome (ancoracyst). The Ancoracysta mitochondrion has a gene-rich genome with a coding capacity exceeding that of all other eukaryotes except the distantly related jakobids and Diphylleia, and it uniquely possesses heterologous, nucleus-, and mitochondrion-encoded cytochrome c maturase systems. To comprehensively examine mitochondrial genome reduction, we also assembled mitochondrial genomes from picozoans and colponemids and re-annotated existing mitochondrial genomes using hidden Markov model gene profiles. This revealed over a dozen previously overlooked mitochondrial genes at the level of eukaryotic supergroups. Analysis of trends over evolutionary time demonstrates that gene transfer to the nucleus was non-linear, that it occurred in waves of exponential decrease, and that much of it took place comparatively early, massively independently, and with lineage-specific rates. This process has led to differential gene retention, suggesting that gene-rich mitochondrial genomes are not a product of their early divergence. Parallel transfer of mitochondrial genes and their functional replacement by new nuclear factors are important in models for the origin of eukaryotes, especially as major gaps in our knowledge of eukaryotic diversity at the deepest level remain unfilled

    En el artículo se examinan la obra y el legado del francés Alexis Carrel (1873-1944), ganador del Premio Nobel, como caso paradigmático del modernismo reaccionario y el pesimismo cultural del periodo de entreguerras. Preocupado por la "crisis de la civilización", en 1935 Carrel publicó La incógnita del hombre, un libro en el que proponía la reconstrucción del individuo a partir de un conjunto de medidas fascistas y eugenésicas. El éxito de la obra convirtió a su autor en uno de los divulgadores del racismo científico más populares de la época. Entre 1941 y 1944 trabajó para el régimen colaboracionista de Vichy dirigiendo un instituto de investigaciones sociobiológicas que tenía por misión "mejorar" la población. Tras su muerte, y pese a haber apoyado explícitamente la política biológicoracial de Hitler, Carrel ha sido reivindicado con propósitos de lo más diversos, desde el humanismo católico y la clonación hasta el racismo antiárabe y el fundamentalismo islámico.The article examines the career and legacy of the French-born Nobel laureate Alexis Carrel (1873-1944) as a paradigmatic case of interwar reactionary modernism and cultural despair. Concerned about the "crisis of civilization", in 1935 Carrel published Man, the Unknown, a book in which he proposed the reconstruction of the individual along fascist and eugenic lines. The book´s success turned the author into one of the most popular vulgarizers of scientific racism. Between 1941 and 1944 he worked for the collaborationist regime of Vichy, heading an institution of sociobiological research aimed at the "improvement" of the population. After his death, and despite his endorsement of Nazi racialbiological policies, Carrel has been claimed for widely different purposes, from cloning research to anti-Arab racism and Islamic fundamentalism.Adams, Mark B.

    Fables, Vol. I

    No full text
    Eighteen months ago I thought that purchasing a set of Rousset for about 150mighthavebeenamistake.NowpurchasingasetofRoussetfor150 might have been a mistake. Now purchasing a set of Rousset for 300 may have been another mistake. But it has been a fascinating mistake! Why? First, this set of four volumes is signed by the author. Secondly, there is a surprising pattern: though some images overlap in the two sets, images missing in that set are in this set and vice versa. Thus this copy lacks the decorative title-page, an image of an inscribed log with surrounding leafage. On that page we find In this deep impression "Imp. Dantzell. Lyon," about as close as either version comes to announcing a publisher. Our new volume has a title-page beginning Livre I with a cherub. Our new volume does not have for the first fable the full-page image of a figure (Poesie?) looking over the shoulder of another figure (Sagesse?). But fable II in the new-bought copy has an image of a narcissus and a butterfly. It has full-page images for Fables III and VI but none for VII, which has an image in the earlier copy. And so it goes, apparently throughout the volume. How strange! At last in Book II Fable III both have the identical full-page illustration. There is a third anomaly here. The printer or bookbinder botched his job! This volume is missing 121 to 172. It skips from III 5 to IV 6. That segment is found in the middle of an even greater lapse in the second volume (120 to 240). My! In this volume, a particularly good image portrays a group of rats abandoning a house for Book II Fable VIII, an illustration not present in the other version. Another is "Lion and Ass" facing 280 (also not in the earlier copy). My favorite printer's device is on 58: A lion plays piano. Many of these devices are lively! The illustration facing 52 has a fine moral: "Les bons et les méchants pursuivent le Bonheur. Mais les bons seuls peuvent l'atteindre." 285 pages, followed by a T of C for the five books here. The illustrated interior title-page pays homage to Aesop and La Fontaine. I am not so sure the fables do. 5.5" x 8.5".This is a hardbound book (hard cover)Language note: FrenchAlexis Rousse

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Jurídicas, Programa de Pós-Graduação em Direito, Florianópolis, 2012.Nesse trabalho será explorada a ideia de descentralização política e administrativa no Brasil no período do Segundo Reinado, no pensamento político de Tavares Bastos. Esse autor inova ao apresentar uma proposta de reforma que pretende solucionar de forma conjunta os problemas políticos e sociais de sua época. Questões como a educação, a abolição da escravidão, a imigração estrangeira, a liberdade de cabotagem, são alguns dos temas levantados pelo autor nesse sentido. Pretendia propor um modelo de Estado que tinha como principal objetivo o desenvolvimento moral e material do país. Para tanto adotou a via da descentralização política e administrativa, como forma de promoção de uma política voltada para a liberdade, preocupada com a sorte do povo e comprometida com o desenvolvimento do país. Assim, pretendeu-se relacionar os direitos fundamentais defendidos e promovidos pelo autor para demonstrar que a descentralização aparece como aspecto fundamental para o exercício da liberdade e à promoção do progresso. Abstract: In this paper we explore the idea of political and administrative decentralization in Brazil during the Empire, the political thoughts of Tavares Bastos. This author innovates to propose a reform intended to address jointly the political and social problems of his time. Issues such as education, the abolition of slavery, foreign immigration, freedom of cabotage between ports, are some of the issues brought by the author in this regard. He intended to propose a model of state which had as main objective the moral and material development of the country. For both adopted the path of political and administrative decentralization as a way of promoting a political freedom, worried about the fate of the people and committed to the development of the country. Thus, we sought to relate the fundamental rights protected and promoted by the author to demonstrate that decentralization appears as a fundamental aspect to the exercise of freedom and the promotion of progress

    Quantitative approach to extension and fault characterization within the central and northern Llanos basin, Colombia

    No full text
    The author has granted permission for their work to be available to the general public.The early Llanos basin developed during the Paleozoic–Mesozoic in a volcanic back arc, formed by subduction along the northwestern corner of the South American plate. In the Cenozoic, accretion of the Panama arch uplifted the Cordillera and isolated the eastern side of the basin into the current configuration. Two major depocenters were present in the northern and central-western Llanos basin, respectively: the Arauca graben resulted from early Paleozoic rifting, and uplift of the Eastern Cordillera led to flexural depression of the lithosphere. Variations in basin depth between these two depocenters and the eastern forebulge, affected fault populations and the distribution of lateral extension within the basin. Extension was calculated from line length balancing along eight sections across the basin, and the results compared with thickness of basin fill, fault population, and basement structure. This study quantitatively demonstrates that extension is greater in areas of thicker basin fill, yet fault population (principally antithetic faults) increases within thinner sections. Distribution of oil fields apparently follows the areas of high fault population, rather than areas of high lateral extension. Overall, NNE–SSW fault orientations in the Casanare domain provide better seals for oil accumulation than the ENE–WSW fault orientations in the Arauca area.Geoscience

    Enhanced Laterally Resolved ToF-SIMS and AFM Imaging of the Electrically Conductive Structures in Cable Bacteria

    No full text
    Cable bacteria are electroactive bacteria that form a long, linear chain of ridged cylindrical cells. These filamentous bacteria conduct centimeter-scale long-range electron transport through parallel, interconnected conductive pathways of which the detailed chemical and electrical properties are still unclear. Here, we combine time-of-flight secondary-ion mass spectrometry (ToF-SIMS) and atomic force microscopy (AFM) to investigate the structure and composition of this naturally occurring electrical network. The enhanced lateral resolution achieved allows differentiation between the cell body and the cell-cell junctions that contain a conspicuous cartwheel structure. Three ToF-SIMS modes were compared in the study of so-called fiber sheaths (i.e., the cell material that remains after the removal of cytoplasm and membranes, and which embeds the electrical network). Among these, fast imaging delayed extraction (FI-DE) was found to balance lateral and mass resolution, thus yielding the following multiple benefits in the study of structure-composition relations in cable bacteria: (i) it enables the separate study of the cell body and cell-cell junctions; (ii) by combining FI-DE with in situ AFM, the depth of Ni-containing protein - key in the electrical transport - is determined with greater precision; and (iii) this combination prevents contamination, which is possible when using an ex situ AFM. Our results imply that the interconnects in extracted fiber sheaths are either damaged during extraction, or that their composition is different from fibers, or both. From a more general analytical perspective, the proposed methodology of ToF-SIMS in the FI-DE mode combined with in situ AFM holds great promise for studying the chemical structure of other biological systems.BT/Environmental Biotechnolog
