The Nobel Prize in Physics 2015: The discovery of neutrino oscillations, which shows that neutrinos have mass

23.05.2016, 16:15, Hoersaal 6

The 2015 Physics Nobel Prize was awarded to Takaaki Kajita and Arthur B.
McDonald. They were the leading scientists in two experiments,
SuperKamiokande and Sudbury Neutrino Observatory (SNO), which demonstrated
that neutrinos can change their type, the so-called flavor, while they
travel through space. This phenomenon is interpreted as `neutrino
oscillations\', which requires that neutrinos have a non-zero mass. This is
the first discovery of physics beyond the Standard Model of Particle
Physics, which assumed neutrinos to be massless. I introduce the physics of
neutrinos and the experiments which led to this breakthrough. Then I
discuss its theoretical interpretation and possible consequences for
particle physics and cosmology.

Viele Gruesse,

Force measurements for the quantification of molecular interactions, cell adhesion and cell mechanics

02.05.2016, 16:15, Hoersaal 6

Forces and mechanical properties play a central role in many biological processes covering a huge range of length and time scales: from the movement of whole organisms over the adhesion, migration, proliferation of cells, down to the mechanics and interactions of single molecules. For example, cells are able to sense external forces (mechanosensing), translate these mechanical forces into biochemical signals (mechanotransduction) and react to these signals (mechanoresponse). Mechanics also plays an important role on the level of single biomolecules. For example, forces act between ligands and receptors, forces induce conformational changes in biomolecules, and the mechanical properties of biomolecules are often related to their function.
In this talk, I will first focus on recent work in my lab related to mechanical interactions between cells and the extracellular matrix (ECM) critical to the metastasis of cancer cells. To assess the mechanical interplay between the cells and ECM during invasion, we combined confocal fluorescence microscopy and atomic force microscopy (AFM) indentation to determine the Young’s moduli of individual embedded cells and the pericellular matrix using novel analysis methods for heterogeneous samples. In the second part of my talk, I will discuss how physical properties of fibrinogen matrices control the adhesion of blood cells. The adsorption of fibrinogen on fibrin clots and other surfaces strongly reduces integrin-mediated adhesion of platelets and leukocytes with implications for the surface-mediated control of thrombus growth and blood compatibility of biomaterials. We applied AFM based force spectroscopy techniques combined with optical microscopy to quantify the adhesive properties of fibrinogen matrixes on the single cell level and studied the mechanism behind the transformation of highly adhesive to non-adhesive surfaces.
