    Quatorze antibiotiques ont été retrouvés dans les rivières de 72 pays, d’après une étude britannique inédite révélée lundi 27 mai. Les concentrations d’antibiotiques trouvés dépassent jusqu’à 300 fois les niveaux « acceptables ». Un risque majeur puisque ce phénomène accentue le phénomène de résistance aux antibiotiques qui deviennent moins efficaces pour traiter certains symptômes.

    Aucune n’est épargnée. Une étude présentée lundi 27 mai révèle que, de l’Europe à l’Asie en passant par l’Afrique, les concentrations d’antibiotiques relevées dans certaines rivières du monde dépassent largement les niveaux acceptables. La nouveauté de cette étude résulte du fait qu’il s’agit désormais d’un « problème mondial » car si, autrefois, les niveaux tolérés étaient le plus souvent dépassés en Asie et en Afrique - les sites les plus problématiques se trouvent au Bangladesh, Kenya, Ghana, Pakistan et Nigeria - l’Europe et l’Amérique ne sont plus en reste, note le communiqué de l’équipe de chercheurs de l’université britannique de York responsable de l’étude.

    Les scientifiques ont ainsi analysé des prélèvements effectués sur 711 sites dans 72 pays sur six continents et ont détecté au moins un des 14 antibiotiques recherchés dans 65% des échantillons. Les chercheurs, qui présentaient leurs recherches lundi à un congrès à Helsinki, ont comparé ces prélèvements aux niveaux acceptables établis par le groupement d’industries pharmaceutiques AMR Industry Alliance, qui varient selon la substance.

    Résultat, le métronidazole, utilisé contre les infections de la peau et de la bouche, est l’antibiotique qui dépasse le plus ce niveau acceptable, avec des concentrations allant jusqu’à 300 fois ce seuil sur un site au Bangladesh. Le niveau est également dépassé dans la Tamise. La ciprofloxacine est de son côté la substance qui dépasse le plus souvent le seuil de sûreté acceptable (sur 51 sites), tandis que le triméthoprime, utilisé dans le traitement des infections urinaires, est le plus fréquemment retrouvé.

    • Est-ce que c’est des antibiotiques qu’on prescrit aux humain·es ou aux non-humain·es ?

      Antibiotics found in some of the world’s rivers exceed ‘safe’ levels, global study finds - News and events, The University of York
      https://www.york.ac.uk/news-and-events/news/2019/research/antibiotics-found-in-some-of-worlds-rivers
      https://www.york.ac.uk/media/news-and-events/pressreleases/2019/Global rivers feat.jpg

      Concentrations of antibiotics found in some of the world’s rivers exceed ‘safe’ levels by up to 300 times, the first ever global study has discovered.
      […]
      Researchers looked for 14 commonly used antibiotics in rivers in 72 countries across six continents and found antibiotics at 65% of the sites monitored.

      Metronidazole, which is used to treat bacterial infections including skin and mouth infections, exceeded safe levels by the biggest margin, with concentrations at one site in Bangladesh 300 times greater than the ‘safe’ level.

      In the River Thames and one of its tributaries in London, the researchers detected a maximum total antibiotic concentration of 233 nanograms per litre (ng/l), whereas in Bangladesh the concentration was 170 times higher.

      Trimethoprim
      The most prevalent antibiotic was trimethoprim, which was detected at 307 of the 711 sites tested and is primarily used to treat urinary tract infections.

      The research team compared the monitoring data with ‘safe’ levels recently established by the AMR Industry Alliance which, depending on the antibiotic, range from 20-32,000 ng/l.

      Ciproflaxacin, which is used to treat a number of bacterial infections, was the compound that most frequently exceeded safe levels, surpassing the safety threshold in 51 places.

      Global problem
      The team said that the ‘safe’ limits were most frequently exceeded in Asia and Africa, but sites in Europe, North America and South America also had levels of concern showing that antibiotic contamination was a “global problem.”

      Sites where antibiotics exceeded ‘safe’ levels by the greatest degree were in Bangladesh, Kenya, Ghana, Pakistan and Nigeria, while a site in Austria was ranked the highest of the European sites monitored.

      The study revealed that high-risk sites were typically adjacent to wastewater treatment systems, waste or sewage dumps and in some areas of political turmoil, including the Israeli and Palestinian border.

      Monitoring
      The project, which was led by the University of York, was a huge logistical challenge – with 92 sampling kits flown out to partners across the world who were asked to take samples from locations along their local river system.

      Samples were then frozen and couriered back to the University of York for testing. Some of the world’s most iconic rivers were sampled, including the Chao Phraya, Danube, Mekong, Seine, Thames, Tiber and Tigris.

      3.12 - New Insights into Chemical Exposures over Multiple Spatial and Temporal Scales
      Co-chairs: Alistair Boxall, Charlotte Wagner, Rainer Lohmann, Jason Snape 

      Tuesday May 28, 2019 | 13:55–15:30 | Session Room 204/205 

      Current methods used to assess chemical exposures are insufficient to accurately establish the impacts of chemicals on human and ecosystem health. For example, exposure assessment often involves the use of averaged concentrations, assumes constant exposure of an organism and focuses on select geographical regions, individual chemicals and single environmental compartments. A combination of tools in environmental scientists’ toolbox can be used to address these limitations.

      This session will therefore include presentations on experimental and modelling approaches to better understand environmental exposures of humans and other organisms to chemicals over space and time, and the drivers of such exposures. We welcome submissions from the following areas:
      1) Applications of novel approaches such as source apportionment, wireless sensor networks, drones and citizen science to generate and understand exposure data over multiple spatial and temporal scales,
      2) Advancements in assessing exposures to multiple chemicals and from different land-use types, as well as the impact of an organism’s differing interactions with its environment, and
      3) Quantification of chemical exposures at regional, continental and global geographical scales.

      This session aims at advancing efforts to combine models and measurement to better assess environmental distribution and exposure to chemical contaminants, reducing ubiquitous exposures and risks to public and environmental health.

  • The Woman With Lapis Lazuli in Her Teeth - The Atlantic
    https://www.theatlantic.com/science/archive/2019/01/the-woman-with-lapis-lazuli-in-her-teeth/579760

    Who was that person? A woman, first of all. According to radiocarbon dating, she lived around 997 to 1162, and she was buried at a women’s monastery in Dalheim, Germany. And so these embedded blue particles in her teeth illuminate a forgotten history of medieval manuscripts: Not just monks made them. In the medieval ages, nuns also produced the famously laborious and beautiful books. And some of these women must have been very good, if they were using pigment as precious and rare as ultramarine.

    (...) art experts were still skeptical. Some dismissed the idea that a woman could have been a painter skilled enough to work with ultramarine. One suggested to Warinner that this woman came into contact with ultramarine because she was simply the cleaning lady.

  • Students with lower A Levels from poorly performing schools do just as well on medical degrees - News and events, The University of York
    https://www.york.ac.uk/news-and-events/news/2018/research/students-with-lower-a-levels-do-just-as-well

    Particulièrement intéressant en ces temps de #sélection en #France,

    The research also found that students from poorly performing schools who match the top A Level grades achieved by pupils from the best performing schools, go on to do better during a medical degree.

    The authors of the research are now calling for medical school entry criteria to be relaxed for all pupils applying from low-performing schools.

  • Pourquoi des sourcils expressifs ont pu avoir de l’importance dans l’évolution humaine.

    Why expressive brows might have mattered in human evolution - News and events, The University of York 09/04/2018

    Comme les bois sur un cerf, un front prononcé était un signal permanent de domination et d’agressivité chez nos ancêtres. Les humains modernes l’ont échangé pour un front lisse avec des sourcils plus visibles et poilus capables d’une plus grande gamme de mouvement.

    À l’aide d’un logiciel d’ingénierie 3D, les chercheurs ont examiné l’arête frontale emblématique d’un crâne fossilisé, connu sous le nom de Kabwe 1, conservé dans les collections du Natural History Museum.

    L’auteur principal du document, le Dr Ricardo Godinho, a déclaré, après avoir écarté par essais sur le crane modélisé en 3D que, "puisque la forme de l’arrête frontale [n’était] pas uniquement dictée par les exigences spatiales et mécaniques, et que d’autres explications sur les arrêtes des sourcils comme la sueur ou les cheveux [avait] déjà été écartées, nous suggérons une explication plausible dans la communication sociale "

    Selon les chercheurs, nos fronts communicatifs ont commencé comme un effet secondaire de nos visages devenant progressivement plus petit au cours des 100 000 dernières années. Ce processus est devenu particulièrement rapide au cours des 20 000 dernières années et, plus récemment, au moment où nous sommes passés de chasseurs-cueilleurs à agriculteurs.

  • The #Mediterranean_Missing_Project

    The Mediterranean Missing project is a 1 year ESRC-funded research project and a collaboration between the Centre for Applied Human Rights at the University of York, The International Organisation for Migration, and City University, London. The project seeks to collect data and explore current responses to migrant bodies in the Mediterranean, and the impacts of a missing relative on families left behind. In 2015, over 3,770 refugees and migrants are known to have died at sea while trying to reach Europe. The majority of these people are not identified, and in such cases a family is left in a state of ambiguous loss, unable to fully grieve for their loved one. This project aims to shed light on the policy vacuum at EU and national levels o this issue, through investigating law, policy and practice in Italy and Greece regarding the investigation, identification, burial and repatriation of migrant bodies. Research with families from Syria, Iraq and Tunisia aims to better understand the impacts of missing persons on their families.

    Europe and the people: Examining the EU’s democratic legitimacy examines the concerns across Europe around the democratic legitimacy of EU institutions and the European project as whole. It looks at how the debate about EU democratic legitimacy fits within the broader context of a crisis of institutions at both the national and global levels, particularly in the wake of the 2008 economic crisis. The publication explores the mechanisms through which EU institutions seek to gain democratic legitimacy and how they try to engage the public, comparing and contrasting with other organisations at the national and international levels. It places the debate around European democratic legitimacy within the context of the UK referendum on EU membership, as well as the fallout from the Greek debt crisis. It sets out ideas for potential improvements in how the EU operates to increase its democratic legitimacy and accountability but recognises that some of the challenges will persist irrespective of efforts to reform.

  • Mapping the world’s linguistic diversity—scientists discover links between your genes and the language you speak

    http://phys.org/news/2015-07-world-linguistic-diversityscientists-links-genes.html

    Academics at the University of York have discovered a correlation between genetic and linguistic diversity and concluded that at least in Europe people who speak different languages are also more likely to have a different genetic make-up.

    The study, led by Professor Giuseppe Longobardi in York’s Department of Language and Linguistic Science, in collaboration with geneticists and linguists at the Universities of Ferrara and Modena and Reggio Emilia in Italy, has discovered that language proves a better predictor of genetic differences than the geographical distribution of population.

  • Intellectual Integrity? How to be a public intellectual
    The Integrity Project | Investigating the value of integrity, and the price of doing without it.

    Tiens voilà un truc très “seenthis”, un débat intéressant , utile et urgent en France :) :

    Intellectual Integrity? How to be a public intellectual
    9th—10th July 2013
    University of York

    ******************
    The Integrity Project (www.projectintegrity.wordpress.com) is collaborating with the board of studies for academic practice to organise a series of events on the theme Intellectual Integrity? How to be a public intellectual.

    These events explore the different ways in which the role of public intellectual can be enacted, both inside and outside the academy, and the different pressures, compromises, and opportunities that one aspiring to that role can expect to face. We will ask: what is it to be a public- intellectual, and can one step into the role without compromising one’s integrity?

    Intellectual Integrity? is a chance for new and established academics, public figures, post-grads, students, and York residents to think about and discuss the risks and rewards of stepping outside the university or engaging in academic life as a public intellectual.

    The Integrity Project explores the psychological, social, institutional and political preconditions for acting and speaking with integrity; those which undermine the possibility of maintaining integrity; and the consequences on individuals and societies of widespread failures integrity. Addressing this brings together social anthropologists and sociologists; philosophers and political and cultural theorists; and historians and scholars of literature and the arts. It also involves people actually living and working in circumstances which compromise or enable their acting with integrity, interested in changing or extending those practical circumstances, and reflecting on the benefits and risks of so doing

  • #BDS : British students reject twinning with Israel University.
    http://youthanormalization.blogspot.com/2011/12/bds-british-students-reject-twinning_09.html

    "Student leaders pointed out that the relatively high turnout of voters reflected the importance of the issue to the students.

    Students at Britain’s University of York have rejected a proposal to twin the institution with the Hebrew University in occupied Jerusalem. The vote on the issue was carried out by York University’s Student Union.

    Le plus cocasse est que la proposition de jumelage avec une université israélienne avait pour vocation à lutter contre… l’antisémitisme :

    According to newspaper reports, York student Jacob Campbell proposed the twinning agreement in order to defend Israel and curb what he described as “anti-Semitic” activities in British universities.

    Comme quoi personne n’est dupe.
