Abstract Metagenomics has opened up an entirely new perspective on life. It reveals that microorganisms colonize every environment on the planet and that the diversity studied in the laboratory represents only a tiny fraction of the total. The number of …

Le PIB est devenu le symbole d'une vision du progrès centrée sur la croissance économique. Pourtant, les économistes ont montré qu'il ne constitue un bon indicateur du bien-être social que sous des hypothèses très restrictives. Il ignore notamment les …
