European Journal of Philosophy, EarlyView.Abstract This essay aims to reveal the conceptual unity of an ensemble of concepts of organic, animal, and anthropological life articulated by the young Karl Marx between 1842 and 1844. To lay the groundwork for my analysis, I begin with Marx's general account of “life as activity.” I argue that Marx articulates a hylomorphic theory of organic form in ...

Imaging malaria parasites across scales and time
Journal of Microscopy, EarlyView.Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.
