    Description: The summit crater of Vailulu'u Seamount, the youngest volcano in the Samoan chain, hosts an active hydrothermal system with profound impact on the ocean water column inside and around its crater (2 km wide and 407 m deep at a 593 m summit depth). The turbidity of the ocean water reaches 1.4 NTU, values that are higher than in any other submarine hydrothermal system. The water is enriched in hydrothermal Mn (3.8 ppb) and 3He (1 × 10−11 cc/g) and we measured water temperature anomalies near the crater floor up to 0.2°C. The hydrothermal system shows complex interactions with the ocean currents around Vailulu'u that include tidally-modulated vertical motions of about 40–50 m, and replenishment of waters into the crater through breaches in the upper half of the crater wall. Inside and outside potential density gradients suggest that hydrothermal venting exports substantial amounts of water from the crater (1.3 ± 0.2 × 108 m3/day), which is in good agreement with fluxes obtained from a tracer release experiment inside the crater of Vailulu'u (0.8 × 108 m3/day [Hart et al., 2003]). This mass flux, in combination with the differences in the inside and outside crater temperature, yields a power output of around 760 megawatts, the equivalent of 20–100 MOR black smokers. The Mn output of 300 kg/day is approximately ten times the output of a single black smoker.

    Hydrothermal venting in magma deserts : the ultraslow-spreading Gakkel and Southwest Indian Ridges (2006)

    Description: Detailed hydrothermal surveys over ridges with spreading rates of 50–150 mm/yr have found a linear relation between spreading rate and the spatial frequency of hydrothermal venting, but the validity of this relation at slow and ultraslow ridges is unproved. Here we compare hydrothermal plume surveys along three sections of the Gakkel Ridge (Arctic Ocean) and the Southwest Indian Ridge (SWIR) to determine if hydrothermal activity is similarly distributed among these ultraslow ridge sections and if these distributions follow the hypothesized linear trend derived from surveys along fast ridges. Along the Gakkel Ridge, most apparent vent sites occur on volcanic highs, and the extraordinarily weak vertical density gradient of the deep Arctic permits plumes to rise above the axial bathymetry. Individual plumes can thus be extensively dispersed along axis, to distances 〉200 km, and ∼75% of the total axial length surveyed is overlain by plumes. Detailed mapping of these plumes points to only 9–10 active sites in 850 km, however, yielding a site frequency F s , sites/100 km of ridge length, of 1.1–1.2. Plumes detected along the SWIR are considerably less extensive for two reasons: an apparent paucity of active vent fields on volcanic highs and a normal deep-ocean density gradient that prevents extended plume rise. Along a western SWIR section (10°–23°E) we identify 3–8 sites, so F s = 0.3–0.8; along a previously surveyed 440 km section of the eastern SWIR (58°–66°E), 6 sites yield F s = 1.3. Plotting spreading rate (us) versus F s, the ultraslow ridges and eight other ridge sections, spanning the global range of spreading rate, establish a robust linear trend (F s = 0.98 + 0.015us), implying that the long-term heat supply is the first-order control on the global distribution of hydrothermal activity. Normalizing F s to the delivery rate of basaltic magma suggests that ultraslow ridges are several times more efficient than faster-spreading ridges in supporting active vent fields. This increased efficiency could derive from some combination of three-dimensional magma focusing at volcanic centers, deep mining of heat from gabbroic intrusions and direct cooling of the upper mantle, and nonmagmatic heat supplied by exothermic serpentinization.

    Evolutionary history of Salmonella typhi (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-25
    Description: For microbial pathogens, phylogeographic differentiation seems to be relatively common. However, the neutral population structure of Salmonella enterica serovar Typhi reflects the continued existence of ubiquitous haplotypes over millennia. In contrast, clinical use of fluoroquinolones has yielded at least 15 independent gyrA mutations within a decade and stimulated clonal expansion of haplotype H58 in Asia and Africa. Yet, antibiotic-sensitive strains and haplotypes other than H58 still persist despite selection for antibiotic resistance. Neutral evolution in Typhi appears to reflect the asymptomatic carrier state, and adaptive evolution depends on the rapid transmission of phenotypic changes through acute infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2652035/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2652035/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roumagnac, Philippe -- Weill, Francois-Xavier -- Dolecek, Christiane -- Baker, Stephen -- Brisse, Sylvain -- Chinh, Nguyen Tran -- Le, Thi Anh Hong -- Acosta, Camilo J -- Farrar, Jeremy -- Dougan, Gordon -- Achtman, Mark -- 076962/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1301-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Infektionsbiologie, Department of Molecular Biology, Chariteplatz 1, 10117 Berlin, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124322" target="_blank"〉PubMed〈/a〉

    Stabilizing isopeptide bonds revealed in gram-positive bacterial pilus structure (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-12-08
    Description: Many bacterial pathogens have long, slender pili through which they adhere to host cells. The crystal structure of the major pilin subunit from the Gram-positive human pathogen Streptococcus pyogenes at 2.2 angstroms resolution reveals an extended structure comprising two all-beta domains. The molecules associate in columns through the crystal, with each carboxyl terminus adjacent to a conserved lysine of the next molecule. This lysine forms the isopeptide bonds that link the subunits in native pili, validating the relevance of the crystal assembly. Each subunit contains two lysine-asparagine isopeptide bonds generated by an intramolecular reaction, and we find evidence for similar isopeptide bonds in other cell surface proteins of Gram-positive bacteria. The present structure explains the strength and stability of such Gram-positive pili and could facilitate vaccine development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kang, Hae Joo -- Coulibaly, Fasseli -- Clow, Fiona -- Proft, Thomas -- Baker, Edward N -- New York, N.Y. -- Science. 2007 Dec 7;318(5856):1625-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Maurice Wilkins Centre for Molecular Biodiscovery, University of Auckland, Auckland 1010, New Zealand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18063798" target="_blank"〉PubMed〈/a〉

    Publication Date: 2007-06-16
    Description: Tilman et al. (Reports, 8 December 2006, p. 1598) argued that low-input high-diversity grasslands can provide a substantial proportion of global energy needs. We contend that their conclusions are not substantiated by their experimental protocol. The authors understated the management inputs required to establish prairies, extrapolated globally from site-specific results, and presented potentially misleading energy accounting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Russelle, Michael P -- Morey, R Vance -- Baker, John M -- Porter, Paul M -- Jung, Hans-Joachim G -- New York, N.Y. -- Science. 2007 Jun 15;316(5831):1567; author reply 1567.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Agriculture, Agricultural Research Service, St. Paul, MN 55108, USA. michael.russelle@ars.usda.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17569846" target="_blank"〉PubMed〈/a〉

    A common variant on chromosome 9p21 affects the risk of myocardial infarction (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-05
    Description: The global endemic of cardiovascular diseases calls for improved risk assessment and treatment. Here, we describe an association between myocardial infarction (MI) and a common sequence variant on chromosome 9p21. This study included a total of 4587 cases and 12,767 controls. The identified variant, adjacent to the tumor suppressor genes CDKN2A and CDKN2B, was associated with the disease with high significance. Approximately 21% of individuals in the population are homozygous for this variant, and their estimated risk of suffering myocardial infarction is 1.64 times as great as that of noncarriers. The corresponding risk is 2.02 times as great for early-onset cases. The population attributable risk is 21% for MI in general and 31% for early-onset cases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Helgadottir, Anna -- Thorleifsson, Gudmar -- Manolescu, Andrei -- Gretarsdottir, Solveig -- Blondal, Thorarinn -- Jonasdottir, Aslaug -- Jonasdottir, Adalbjorg -- Sigurdsson, Asgeir -- Baker, Adam -- Palsson, Arnar -- Masson, Gisli -- Gudbjartsson, Daniel F -- Magnusson, Kristinn P -- Andersen, Karl -- Levey, Allan I -- Backman, Valgerdur M -- Matthiasdottir, Sigurborg -- Jonsdottir, Thorbjorg -- Palsson, Stefan -- Einarsdottir, Helga -- Gunnarsdottir, Steinunn -- Gylfason, Arnaldur -- Vaccarino, Viola -- Hooper, W Craig -- Reilly, Muredach P -- Granger, Christopher B -- Austin, Harland -- Rader, Daniel J -- Shah, Svati H -- Quyyumi, Arshed A -- Gulcher, Jeffrey R -- Thorgeirsson, Gudmundur -- Thorsteinsdottir, Unnur -- Kong, Augustine -- Stefansson, Kari -- New York, N.Y. -- Science. 2007 Jun 8;316(5830):1491-3.
