Light sheet microscopy is an easy to implement and extremely powerful alternative to established fluorescence imaging techniques such as laser scanning confocal, multi‐photon and spinning disk microscopy. By illuminating the sample only with a thin slice of light, photo‐bleaching is reduced to a minimum, making light sheet microscopy ideal for non‐destructive imaging of fragile samples over extended periods of time. Millimeter‐sized samples can be imaged rapidly with high resolution and high depth penetration. A large variety of instruments have been developed (...) and optimized for a number of different samples: Bessel beams form thin light sheets for single cells, and selective plane illumination microscopy (SPIM) offers multi‐view acquisition to image entire embryos with isotropic resolution. This review explains how light sheet microscopy involves a conceptually new microscope design and how it changes modern imaging in biology. (shrink)

In this article, I compare the ways in which Baudrillard and Heidegger seek to bring attention to the importance of death for our personal existential situation which has now become repressed in conceptions of existence and society. Heidegger critiques public conceptions of death that serve to cover up its importance. Less well known is that, somewhat in parallel fashion, Baudrillard charts a ‘genealogy’ of the ‘extradition’ of the dead from the centre of the social and he claims that we live (...) currently in a death denying society. This reduces the meaning of our own impending deaths. However, unlike Heidegger, Baudrillard’s ‘genealogical’ critique of the exclusion of death in modern society is not a one-way dismissal because he proposes an alternative social role for death in the form of ‘primitive symbolic exchange’.
