SUMMARY:Physics Colloquium: Prof. Ed Lattman
DESCRIPTION:Professor Ed Lattman\, Principal Research Scientist at the Hauptman-Woodward Institute; Professor of Structural Biology & Materials Design and Innovation at the University of Buffalo (SUNY) \nOf Course\, an STC is Only a Means to An End\, Which Is (Hopefully) Science \nNSF Science and Technology Centers are large\, prestigious awards intended to enable transformative research that cannot readily be carried out by individual investigators. STCs usually involve a set of institutions. Using as an example an individual STC – Biology with X-ray Lasers or BioXFEL – this colloquium will discuss both the science behind the Center\, and a variety of non-research related benefits and burdens associated with it. These include the capacity to create significant and impactful education programs.  It will also touch upon what is needed – in addition to good luck – to gain such an award and to ensure its renewal.

SUMMARY:Physics Colloquium: Professor Yuval Garini
DESCRIPTION:Professor Yuval Garini\, Physics Dept. and Institute of Nanotechnology\, Bar Ilan University\, Israel \nStudying Chromatin Dynamics by Advanced Live Cell Imaging Methods \nThe DNA in a human cell (which is ~3 meters long) is packed in a tiny nucleus of ~10 μm radius. Although it is dynamic\, it is well organized. By using advanced microscopy methods for live cell imaging\, we study the mechanisms that organizes the chromatin in the nucleus. We identified a dynamic structure that was not known before that we call the ‘DNA matrix’. \nThese methods allowed us to identify that a protein\, lamin A\, forms chromatin loops thereby restricting the chromatin dynamics significantly in the whole nucleus volume. The methods we use are based on measuring the signal and fluctuations of fluorescent molecules and the use of biophysical models based on Smoluchowski equation and modified diffusion equations. It allowed us to identify not only the type of the protein\, but also its bound and free fractions\, concentration and diffusion properties. \nThe methods include single particle tracking\, a new method that we have developed named time resolved intensity photobleaching (TRIP)\, as well as fluorescence correlation spectroscopy (FCS) and single particle tracking (SPT). We also use single-molecule methods for verifying the DNA-protein interaction\, including tethered particle motion (TPM) and atomic force microscopy (AFM). The methods\, their use\, the biophysical modeling and the biological insight\, will be described.
