1. Celestial Orientation in Dim Light
Abstract : The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. READ MORE

2. Regulation of GRAF1 membrane sculpting function during cell movement
Abstract : All eukaryotic cells rely on endocytic events to satisfy a constant need for nutrient and fluid uptake from their surroundings. Endocytosis-dependent turnover of cell surface constituents also serves to control signal transduction and establish morphological changes in response to extracellular stimuli. READ MORE

3. Nuclear pore membrane glycoprotein 210 as a new marker for epithelial cells
Abstract : Epithelial cell polarisation is a prerequisite for the branching morphogenesis in several organs. Differential screening techniques were used to identify genes, which are upregulated during induction of epithelium in early kidney development. READ MORE

4. Theoretical Studies of Spin-Dependent Quantum Phenomena in Semiconductor Nanostructures
Abstract : The study of spin transport has emerged at the forefront of condensed matter physics during the last decade. Much of the interest has undoubtedly been sparked by the advent of the spintronics paradigm and the idea of creating novel electronic devices based on the spin degree of freedom of the carriers.

5. Majorana Representation in Quantum Optics : SU(2) Interferometry and Uncertainty Relations
Abstract : The algebra of SU(2) is ubiquitous in physics, applicable both to the atomic spin states and the polarisation states of light. The method developed by Majorana and Schwinger to represent pure, symmetric spin-states of arbitrary value as a product of spin-1/2 states is a powerful tool that allows for a great conceptual and practical simplification.
