Description: Extremely low frequency magnetic fields (ELF-MF) are common environmental agents that are suspected to promote later stages of tumorigenesis, especially in brain-derived malignancies. Even though ELF magnetic fields have been previously linked to increased proliferation in neuroblastoma cells, no previous work has studied whether ELF-MF exposure may change key biomolecular features, such as anti-glycative defence and energy re-programming, both of which are currently considered as crucial factors involved in the phenotype and progression of many malignancies. Our study investigated whether the hyperproliferation that is induced in SH-SY5Y human neuroblastoma cells by a 50 Hz, 1 mT ELF magnetic field is supported by an improved defense towards methylglyoxal (MG), which is an endogenous cancer-static and glycating α-oxoaldehyde, and by rewiring of energy metabolism. Our findings show that not only the ELF magnetic field interfered with the biology of neuron-derived malignant cells, by de-differentiating further the cellular phenotype and by increasing the proliferative activity, but also triggered cytoprotective mechanisms through the enhancement of the defense against MG, along with a more efficient management of metabolic energy, presumably to support the rapid cell outgrowth. Intriguingly, we also revealed that the MF-induced bioeffects took place after an initial imbalance of the cellular homeostasis, which most likely created a transient unstable milieu. The biochemical pathways and molecular targets revealed in this research could be exploited for future approaches aimed at limiting or suppressing the deleterious effects of ELF magnetic fields.

Description: Oil-in-water emulsions have been successfully used to increase the efficacy, immunogenicity, and cross-protection of human vaccines; however, their mechanism of action is still largely unknown. Nlrp3 inflammasome has been previously associated to the activity of alum, another adjuvant broadly used in human vaccines, and MyD88 adaptor protein is required for the adjuvanticity of most Toll-like receptor agonists. We compared the contribution of Nlrp3 and MyD88 to the adjuvanticity of alum, the oil-in-water emulsion MF59, and complete Freund's adjuvant in mice using a three-component vaccine against serogroup B Neisseria meningitidis (rMenB). Although the basal antibody responses to the nonadjuvanted rMenB vaccine were largely dependent on Nlrp3, the high-level antibody responses induced by alum, MF59, or complete Freund's adjuvant did not require Nlrp3. Surprisingly, we found that MF59 requires MyD88 to enhance bactericidal antibody responses to the rMenB vaccine. Because MF59 did not activate any of the Toll-like receptors in vitro, we propose that MF59 requires MyD88 for a Toll-like receptor-independent signaling pathway.

Description: Agulhas rings provide the principal route for ocean waters to circulate from the Indo-Pacific to the Atlantic basin. Their influence on global ocean circulation is well known, but their role in plankton transport is largely unexplored. We show that, although the coarse taxonomic structure of plankton communities is continuous across the Agulhas choke point, South Atlantic plankton diversity is altered compared with Indian Ocean source populations. Modeling and in situ sampling of a young Agulhas ring indicate that strong vertical mixing drives complex nitrogen cycling, shaping community metabolism and biogeochemical signatures as the ring and associated plankton transit westward. The peculiar local environment inside Agulhas rings may provide a selective mechanism contributing to the limited dispersal of Indian Ocean plankton populations into the Atlantic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Villar, Emilie -- Farrant, Gregory K -- Follows, Michael -- Garczarek, Laurence -- Speich, Sabrina -- Audic, Stephane -- Bittner, Lucie -- Blanke, Bruno -- Brum, Jennifer R -- Brunet, Christophe -- Casotti, Raffaella -- Chase, Alison -- Dolan, John R -- d'Ortenzio, Fabrizio -- Gattuso, Jean-Pierre -- Grima, Nicolas -- Guidi, Lionel -- Hill, Christopher N -- Jahn, Oliver -- Jamet, Jean-Louis -- Le Goff, Herve -- Lepoivre, Cyrille -- Malviya, Shruti -- Pelletier, Eric -- Romagnan, Jean-Baptiste -- Roux, Simon -- Santini, Sebastien -- Scalco, Eleonora -- Schwenck, Sarah M -- Tanaka, Atsuko -- Testor, Pierre -- Vannier, Thomas -- Vincent, Flora -- Zingone, Adriana -- Dimier, Celine -- Picheral, Marc -- Searson, Sarah -- Kandels-Lewis, Stefanie -- Tara Oceans Coordinators -- Acinas, Silvia G -- Bork, Peer -- Boss, Emmanuel -- de Vargas, Colomban -- Gorsky, Gabriel -- Ogata, Hiroyuki -- Pesant, Stephane -- Sullivan, Matthew B -- Sunagawa, Shinichi -- Wincker, Patrick -- Karsenti, Eric -- Bowler, Chris -- Not, Fabrice -- Hingamp, Pascal -- Iudicone, Daniele -- New York, N.Y. -- Science. 2015 May 22;348(6237):1261447. doi: 10.1126/science.1261447.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Aix Marseille Universite, CNRS, IGS UMR 7256, 13288 Marseille, France. villar@igs.cnrs-mrs.fr not@sb-roscoff.fr hingamp@igs.cnrs-mrs.fr iudicone@szn.it karsenti@embl.de cbowler@biologie.ens.fr. ; CNRS, UMR 7144, Station Biologique de Roscoff, Place Georges Teissier, 29680 Roscoff, France.

Description: Mulga, comprised of a complex of closely related Acacia spp., grades from a low open forest to tall shrublands in tropical and sub-tropical arid and semi-arid regions of Australia and experiences warm-to-hot annual temperatures and a pronounced dry season. This short synthesis of current knowledge briefly outlines the causes of the extreme variability in rainfall characteristic of much of central Australia, and then discusses the patterns and drivers of variability in carbon and water fluxes of a central Australian low open Mulga forest. Variation in phenology and the impact of differences in the amount and timing of precipitation on vegetation function are then discussed. We use field observations, with particular emphasis on eddy covariance data, coupled with modelling and remote sensing products to interpret inter-seasonal and inter-annual patterns in the behaviour of this ecosystem. We show that Mulga can vary between periods of near carbon neutrality to periods of be...
