Epitope-focused vaccine design to protect against Zika and dengue virus simultaneously

M. Felix Rey   Institut Pasteur (Paris), directeur de l’unité de Virologie structurale Felix Rey is a structural biologist who graduated in theoretical physics in Argentina and later obtained his PhD in biochemistry at the South Paris University in France (in 1988). He then spent 7-years as post-doctoral fellow at Harvard university, until 1995, where he specialized in the structure of viruses. In 1995 he returned to France as Junior PI working at CNRS in Gif-sur-Yvette (Paris area), where in 1999 he became Director of the CNRS Laboratory of Structural and Molecular Virology. ...

Artlingo, les langues autrement dites

Artlingo : Créé à l’Université de Strasbourg sous l’égide des Investissements d’Avenir (IdEx) et à l’initiative de Lara Delage-Toriel et Carole Egger, ARTLINGO est un projet interdisciplinaire innovant destiné à redynamiser le désir d’apprendre en encourageant l’initiative et la créativité des étudiants et des enseignants. Le programme, qui a été mis en place dès la rentrée de septembre 2016, propose un éventail de cours/ateliers en Licence et en Master qui bénéficient du concours de professionnels de différentes pratiques artistiques (théâtre, danse, musique, soundpainting, ...

Comparison of Simulated Tree-Ring Cellulose d180 at the European Scale

In order to investigate factors involved in the inter-annual variability of d180 in tree ring cellulose (d18OTRC), we simulated the d18OTRC from 1960 to 2001 over Europe. We used 1) simulated climate and water isotope fields of REMOiso, a meso-scale circulation model, 2) hypotheses of the distribution of roots and soil hydrology, and 3) a mechanistic model of oxygen-isotopes in tree ring cellulose (d18OTRC). Sensitivity tests show that relative humidity of the air and soil water d18O contribute differently to the d180 in tree ring cellulose according to regional climate. In the commonly observed hydrological situation, humidity of the air ...

Holocene Climatic Changes and Their Effect on Morphodynamics and Sedimentation in Campania

High-resolution paleoclimatic studies (e.g. 18O, 13C, CH4, MS, ect) provide 38 detailed reconstructions of the Holocene climatic variability, but they don’t are unable to provide direct informations about the effects of the climatic changes on landscape and human ecosystems. In order to assess the response of the subaerial geomorphologic/pedo-sedimentary systems to the climatic changes and their potential impact on the ancient human communities, detailed stratigraphical investigations in Campania (southern Italy) have been carried out. In addition to indications provided by litho-pedostratigraphical and geomorphological investigations, the study has recurred to historical, archaeological, and palaeobiological data. Some of the main global cyclical ...

The State of UK Climate Modelling

The UK recently invested £23 million (~US$40 million) in a program in Quantifying and Understanding the Earth SysTem (QUEST). The final product of this investment is the state-of-the-art QUEST Earth System Model (QUESM), which is comprised of the most comprehensive modeling and understanding of terrestrial, atmosphere, and marine processes ever built. QUESM is to be linked with the world-leading Hadley Centre’s GCM to assess and understand changes in the Earth system with respect to climate and global change. Here, I present the state of UK climate modeling, an overview of the QUEST Earth System Model, and detail the individual sub-models ...

Data-Model Fusion Approach in Global Change Research: Recent Development and Future Challenges

It is increasingly recognized that global change research requires methods and strategies for combing process models and data in systematic ways. This is leading to research towards the application of model-data fusion approach. The model-data fusion is a new quantitative approach to model analysis and data assimilation that provides a high level of empirical constraint over model predictions based on observations. Applications of model-data fusion require (a) a model that describes the underlying physical, chemical and biological processes, (b) experimental observations and (c) an optimization tool. The optimization tool is used to find optimal estimates of model parameters or states ...

Setting Cumulative Emissions Targets to Reduce the Risk of "Dangerous" Climate Change

The ultimate objective of climate change mitigation is to reduce the amount of anthropogenic greenhouse gas (GHG) emissions in order to achieve “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system” (UNFCCC, Article 2). This statement raises a number of questions regarding (i) what “dangerous interference” means, (ii) what GHG concentration level may considered “safe”, and (iii) what emissions pathway should be taken towards stabilization. Here we present a novel approach to coupled climate-carbon cycle modelling which allows one to estimate the probability that any given level of ...

Industrial and Environmental Policies: Reciprocal Impacts

Total as a key player of the Oil and Gas industry is providing answers to 25 environmental challenges. In that respect, it has already developed environmental objectives and policies. Its environmental footprints is being assessed, controlled and reduced with a set of concrete means to improve its performance, a better selection of major challenges and a better report to external stake holders. Energy and climate issues are inextricably interwoven, which means that we have to help to reconcile the objectives of today’s society, pursuing economic growth while protecting the climate for future generations. Faced with this predicament, we are ...

The Costs of Strategic Adaptation in a Simple Conceptual of Climate Change

A simple theoretical model of the process of strategic adaptation to climate change is proposed. Climate change is represented by a non-stationary Markov process on the space of climate states, and strategic adaptation by a simple resource allocation task in which agents incur costs when moving resources from one activity to another. A stationary analysis allows diagnostics that quantify the net costs of climate change, and the long-run benefits to adaptation, to be defined. A full dynamic analysis of the model 74 allows for the computation of the costs of negotiating the transition between two stationary climate regimes. We analyze ...
