The paper examines the body as a stake in space exploration at the intersection of technology, material practices and utopian imaginaries. Based on an interpretation of the film “Gattaca” in the light of the problem of access to space, the paper opposes two techno-utopian regimes — cosmopolitics and biopolitics. Cosmopolitics assumes an equality of access to space for all beings, while biopolitics links bodily restrictions to the problem of regravitation. Regravitation is the biopolitical practice aimed at preserving the “terrestrial” conditions (...) of the body’s existence. The problem of access to space is exemplified by the debate over the boundary between Earth’s atmosphere and space in the NewSpace movement. A radical step here is taken by space amateurs, defining the stratosphere as “almost space”. In this sense, the amateurs' space techno-utopia turns out to be cosmopolitan — not so much in the sense of space as a political order equal to all beings and entities, but in the sense of a politics of equal access to space beyond Earth. K. E. Tsiolkovsky’s amateur techno-utopia proposes a radical transformation of the body and its liberation from terrestrial gravity. People will become “citizens of the ether” with the help of an extreme environment and gain additional opportunities. (shrink)

Three early 20th-century attempts at unifying separate areas of biology, in particular development, genetics, physiology, and evolution, are compared in regard to their success and fruitfulness for further research: Jacques Loeb’s reductionist project of unifying approaches by physico-chemical explanations; Richard Goldschmidt’s anti-reductionist attempts to unify by integration; and Sewall Wright’s combination of reductionist research and vision of hierarchical genetic systems. Loeb’s program, demanding that all aspects of biology, including evolution, be studied by the methods of the experimental sciences, proved highly (...) successful and indispensible for higher level investigations, even though evolutionary change and properties of biological systems up to now cannot be fully explained on the molecular level alone. Goldschmidt has been appraised as pioneer of physiological and developmental genetics and of a new evolutionary synthesis which transcended neo-Darwinism. However, this study concludes that his anti-reductionist attempts to integrate genetics, development and evolution have to be regarded as failures or dead ends. His grand speculations were based on the one hand on concepts and experimental systems that were too vague in order to stimulate further research, and on the other on experiments which in their core parts turned out not to be reproducible. In contrast, Sewall Wright, apart from being one of the architects of the neo-Darwinian synthesis of the 1930s, opened up new paths of testable quantitative developmental genetic investigations. He placed his research within a framework of logical reasoning, which resulted in the farsighted speculation that examinations of biological systems should be related to the regulation of hierarchical genetic subsystems, possibly providing a mechanism for development and evolution. I argue that his suggestion of basing the study of systems on clearly defined properties of the components has proved superior to Goldschmidt’s approach of studying systems as a whole, and that attempts to integrate different fields at a too early stage may prove futile or worse. © 2011 Elsevier Inc.

The processing of information within the retino-tectal visual system of amphibians is decomposed into five major operational stages, three of them taking place in the retina and two in the optic tectum. The stages in the retina involve (i) a spatially local high-pass filtering in connection to the perception of moving objects, (ii) separation of the receptor activity into ON- and OFF-channels regarding the distinction of objects on both light and dark backgrounds, (iii) spatial integration via near excitation and far-reaching (...) inhibition. Variation of the spatial range of excitation and inhibition allows to account for typical activities observed in a variety of classes of retina ganglion cells.Mathematical description of the operations in the tectum opticum include (i) spatial summation of retinal output (mainly of class-2 and class-3 retina ganglion cells), and (ii) direct or indirect lateral inhibition between tectal cells. In the computer simulation, first the output of the mathematical retina model is computed which, then, is used as the input to the tectum model. The full spatio-temporal dynamics is taken into account. (shrink)
