Le stress des animaux de laboratoire

Les recherches effectuées sur les animaux ont pour but de mieux connaître les maladies et les moyens de les guérir, et d’évaluer la toxicité des médicaments avant qu’ils soient testés sur les êtres humains. En fait, les études menées sur les animaux ont joué un rôle fondamental dans presque tout progrès médical important.

Bien que les chercheurs souhaitent réduire ou remplacer les tests sur les animaux, les moyens technologiques actuels ne permettent pas encore de s’en passer. Le Conseil de bioéthique de Nuffied estime qu’entre 50 et 100 millions d’animaux, des mouches aux singes, sont mis à mort chaque année dans le cadre des recherches scientifiques. Près de 90 pour cent des vertébrés utilisés sont des rongeurs.

Obtenir des informations fiables à partir des expérimentations animales nécessite des paramètres stricts : d’autres scientifiques doivent être à même de les reproduire dans des endroits différents. Pour cela, une compréhension approfondie de chaque espèce animale et de sa biologie est essentielle.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
