    Abstract:

    The contemporary Anthropocene crisis is frequently described as the rarefaction of resources or resources per capita. However, both energy and minerals correspond to fundamentally conserved quantities from a physical perspective. A specific concept is required to understand the rarefaction of these resources. This concept, entropy, pertains to the configurations of energy and matter and not just to their sheer amount. However, the physical concept of entropy is insufficient to understand biological and social organizations. Biological phenomena display both historicity and more synchronic, systemic properties. The concept of anti-entropy stems from the combination of these aspects. We propose that many vulnerabilities of living entities to the changes of the Anthropocene pertain to anti-entropy. They correspond to the entropization of anti-entropy, that is, a loss of organization. They can also be the disruption of anti-entropy production, that is to say, the loss of the ability to produce functional novelties.

    Bernard Stiegler soulignait l’importance de la question de l’entropie, conduisant au concept d’entropocène. L’auteur introduit et illustre ce concept pour montrer sa pertinence d’un point de vue physique, biologique et social.

    Abstract:

    En examinant le second tome de Qu’appelle-t-on panser (1), le théoricien de la biologie et épistémologue Maël Montévil, qui a collaboré avec Bernard Stiegler à la fois sur des questions théoriques et sur des expérimentations territoriales, s’arrête sur le rôle des sciences dans l’Anthropocène pour souligner leur difficulté à penser cette ère et, ce faisant, à prendre soin des vivants, humains et non-humains, des techniques et des sciences elles-mêmes. Stiegler soulignait l’importance de la question de l’entropie, conduisant au concept d’entropocène. L’auteur introduit et illustre ce concept pour montrer sa pertinence d’un point de vue physique, biologique et social. Ce faisant, il insiste sur la parenté mais aussi sur les différences entre ces phénomènes. Dans le cas des humains, les savoirs jouent un rôle central pour lutter contre l’entropie, et les sciences pourraient retrouver leur compte en contribuant au développement – urgent – de savoirs territoriaux.

    A combined morphometric and statistical approach to assess non-monotonicity in the developing mammary gland of rats in the CLARITY-BPA study

    Environmental Health Perspectives


    We can and should take advantage of nonmonotonic properties to perform statistical analysis rigorously by new statistical and morphometric methods.

    Abstract:

    We aimed to a) determine whether BPA showed effects on the developing rat mammary gland using new quantitative and established semiquantitative methods in two laboratories, b) develop a software tool for automatic evaluation of quantifiable aspects of the mammary ductal tree, and c) compare those methods. Conclusions: Both the semiquantitative and the quantitative methods revealed nonmonotonic effects of BPA. The quantitative unsupervised analysis used 91 measurements and produced the most striking nonmonotonic dose–response curves. At all time points, lower doses resulted in larger effects, consistent with the core study, which revealed a significant increase of mammary adenocarcinoma incidence in the stop-dose animals at the lowest BPA dose tested.
