[Illinois] Beckman Graduate Seminar: Dispersion-relation Spectroscopy of Intracellular Transport
18 Dec 2012 | | Contributor(s):: Ru Wang
The interior of a living cell is a busy place. Molecular motors move materials along prescribed biopolymer tracks. This sort of active transport is required to rapidly move products over large distances within the cell, where passive diffusion is too slow. Just as understanding the flow of...
[Illinois] Beckman Graduate Seminar: Membrane Sculpting by F-BAR Domains Studied by Molecular Dynamics Simulations
18 Dec 2012 | | Contributor(s):: Hang Yu
Interplay between cellular membranes and their peripheral proteins drives many processes in eukaryotic cells. Proteins of the Bin/Amphiphysin/Rvs (BAR) domain family, in particular, play a role in cellular morphogenesis, for example curving planar membranes into tubular membranes. However, it is...

[Illinois] Coping with the Unknown: A Guide for Bacteria and Bacteriologists
07 Dec 2012 | | Contributor(s):: Peter Freddolino
Bacteria and other microorganisms rely on a complex sensory and regulatory network in order to respond appropriately to hazards and opportunities in their surroundings. This network, shaped over the evolutionary history of the organism, must provide an internal representation of frequently...
[Illinois] BioEngineering Seminar Series: Novel Receptor-Targeting Radiolabeled Peptides for Cancer Imaging
26 Nov 2012 | | Contributor(s):: Yubin Miao
Gonadotropin-releasing hormone (GnRH) and melanocortin-1 (MC1) receptors are attractive molecular targets for cancer imaging due to their over-expressions on cancer cells. GnRH and alpha-melanocyte stimulating hormone (α-MSH) peptides can bind the GnRH and MC1 receptors with nanomolar...
[Illinois] Beckman Director's Seminar - Quantitative Phase Imaging
26 Nov 2012 | | Contributor(s):: Gabriel Popescu
"Ever since the invention of the microscope in the 17th century, it has been observed that live cells are transparent under visible illumination, i.e. they do not absorb (or scatter) light significantly. Thus, a magnified image of cells will generally exhibit low contrast. In order to overcome...

[Illinois] Nano EP Seminar Series: Dipole Instabilities in AlGaN/GaN Heterostructures and the Direct Generation of Millimeter-Wave Oscillations and Intrinsic Tristability in RTDs
26 Nov 2012 | | Contributor(s):: Paul Douglas Yoder
Negative differential drift velocity in wurtzite GaN has been verified experimentally, yet in spite of the wealth of documented theoretical investigations of GaN-based Gunn diodes, not a single such device has yet been demonstrated. The likelihood of realizing GaN-based k-space transfer devices...
[Illinois] BioNanotechnology Seminar Series Fall 2012: Understanding and Controlling Fibrotic Myocardium
26 Nov 2012 | | Contributor(s):: Guy Genin
Hypertension kills 1 in every 5000 Americans each year and affects the majority of those over the age of 55. Following prolonged hypertension, cardiac fibroblasts within the heart convert to myofibroblasts, a larger, contractile phenotype that produces fibrous connective tissue and thereby...
[Illinois] Microbiology Seminar Series: Salmonella Resistance to Phagocytic Superoxide
26 Nov 2012 | | Contributor(s):: James M. Slauch
"Salmonella cause 1.4 million cases of gastroenteritis and enteric fever per year in the US and lead all other foodborne bacterial pathogens as a cause of death. The long-term objectives of our research are to understand the molecular mechanisms by which Salmonella circumvents the host immune...
