We will concentrate here on the thermodynamics of liquid mixtures containing dissociated salt. We will give a brief background and an introduction to electro-prewetting transitions near charged surfaces. We will then show that colloids can be stabilized by addition of salt without use of surfactants or polymers. When a suitable salt is added to a solvent mixture, the coupling of the colloid's surface chemistry and the preferential solvation of ions leads to a repulsive force between colloids that can overcome van der Waals attraction. This
repulsive force is substantial in a large range of temperatures, mixture composition and
salt concentrations.

"Understanding Robustness in Biology's Molecular Machines"

How does this happen? Where and how does biology achieve the robustness that is essential for achieving similar function across these variations? In this lecture we will explore the nature of structure-function relationships used in a range of biological machines, from ribosomes, as the key machinery of protein synthesis in the cell, to helicases that function in transcription of DNA to RNA, to viral capsid assembly. In each of these systems, we will suggest that these biological machines utilize simple physical principles as constraints that operate on a scale that is largely ignorant of the detailed nature of the chemical make-up of their constituent components. We will illustrate how the key motions necessary for critical steps in protein synthesis by the ribosome and in functional motions that unwind double-stranded DNA as part of the process of transcription rely largely on the architecture and shape of the these macromolecular machines. We will also demonstrate how elements of viral assembly and the composition of virus types can be rationalized from simple considerations of geometry and topology. -

As NGS applications continue to grow, so does the need for more powerful tools to work with less-than-ideal samples. As the core of the SMARTer kits for transcriptome analysis, Clontech’s patented SMART® technology utilizes the template switching activity of reverse transcriptase to enable researchers to analyze their most challenging samples, such as single cells, low-input RNA, noncoding RNA, and RNA from degraded samples. In particular, single-cell RNA-seq is one of the more difficult, and fastest growing, applications of NGS. The high sensitivity and dT-primed protocol of the SMARTer Ultra Low family has made these kits the industry standard for single-cell analysis. Applications of SMART technology are constantly expanding and now include a novel, ligation-free method for generating ChIP (chromatin immunoprecipitation) sequencing libraries. The purpose of this seminar is to take a deeper look into the new technologies being developed for single-cell RNA-seq and other sensitive NGS applications.

In addition to classical lithographic systems, also special methods based on combination of FIB modification of surfaces and their wet etching, selective growth on substrates pre-patterned by FIB or electron beam, and Ge nanowire growth in SEM for real time monitoring will be discussed. -

Connectomics, the generation (at this point through electron microscopy), of a connectivity graph for a volume of neural tissue, is still in its infancy. This talk will survey the road ahead, the various technical and computational problems we face, and the joint MIT/Harvard effort to devise an automated pipeline that will allow researchers to have connectomes generated on demand. -

I will describe activity patterns that we have observed in hippocampal place cell dendrites and the implications for how associative Hebbian learning may take place during behavior. I will also describe the functional micro-organization of grid cells in the medial entorhinal cortex and what the organization might tell us about the circuits that generate grid cell firing patterns.
