Biological Sciences Symposia

 

B01 Gina Sosinsky Memorial Symposium: Imaging of Cellular Communications

Bernard Heymann, Esther Bullitt, Alasdair Steven

Gina Sosinsky's recent passing represents a severe loss. Gina was a valuable contributor to the 3DEM community and a delightful person. We are organizing this symposium to honor her and her work on cellular communication. One of her main interests was the junctions between eukaryotic cells, and how these serve both structural and communication functions. The former is essential to maintain the integrity of tissues, while the latter ensures propagation of signals between cells. Gina made important contributions to how gap junctions form selective channels between cells, and couple their cytoplasms to allow solute exchange. Adherens junctions and desmosomes provide mechanical contacts involved in transmitting force signals. Tight junctions offer selectivity to the passage of solutes in the spaces between cells. Retinoschisin is involved in maintaining the layered structure of the retina. Synaptic transmission affords the communication of information. The extracellular matrix forms a scaffolding for these and other proteins in the interstices between cells. Defects in these proteins cause debilitating diseases. The symposium will highlight the progress that has been made towards determining the structures and functions of proteins mediating cell-cell interactions using electron microscopy, light microscopy and other visualization techniques.

Invited Speakers:

B02 Microstructure Characterization of Food Systems

Jinping Dong, Joel Wallecan

Understanding of microstructure and functionality correlations leads the recent trend in food research. Various microscopy and microanalysis techniques are constantly employed by scientists to characterize food microstructures. However, many challenges are faced in this field due to the high complexity nature of the food. Many unique imaging and characterization methods have been developed in individual labs. There is a high demand for the exchange of experience and knowledge in the field, which is the intent of this symposium. This symposium will present applications of microscopy related techniques to characterize food microstructures and to draw their relationship with functionalities. Topics include, but are not limited to light, fluorescence, electron, ion, x-ray, and spectroscopy based microscopy techniques with their applications in food research.

B03: Imaging the Biology of Cells and Tissues: Just Do It Right

Eduardo Rosa-Molinar, Jay Potts

This symposium will serve as a forum for the exchange of information, ideas, and knowledge regarding rigor and reproducibility in imaging sciences, a topic of increasing frequency and importance. Assuring confidence in and reproducibility of imaging results and their interpretation requires thoughtful consideration of the microscopic and experimental controls and procedures, detailed reporting of experimental design, methodologies, and means of analysis, as well as a review of a long and rich literature in the imaging sciences. Using case studies, panelists will discuss the most significant and recurring imaging issues, strive to reach a consensus about the extent to which rigor and reproducibility is a problem, and, suggest individual and organizational means of addressing the concern. Target attendees include undergraduate and graduate students, post-doctoral researchers, and scientists of all levels of experience/expertise and related backgrounds.

Invited Speakers:

  • Le Trinh, University of Southern California
  • Paul Kulesa, Stower Institute for Medical Research

B04 3D and Intravital Imaging in Development and Beyond

David Entenberg, Kevin Eliceiri, Sandra Rugonyi

While conventional optical imaging tools like 2D in vitro assays offer the ability to tightly and reproducibly control experimental conditions, they do not adequately reflect the topography or diversity of environments encountered by cells in vivo. 3D and intravital imaging can remove these restrictions and restore the heterogeneity of environments present in the living organism. For example, 3D organoid cultures free cells from the culture dish's two dimensional confines revealing more physiologically relevant motility and extracellular matrix interactions; whole mount imaging preserves the structural integrity and spatial arrangement of the living organism; and intravital imaging further restores multiple host cell interactions, connection to lymphatic and vascular circuits and regulatory signals from distant organs. These increasingly more physiological environs come at the price of greatly increased challenges for the design of experiments and extraction of interpretable information from them. This session is intended to be a forum for highlighting new developments and techniques in the art and science of 3D and intravital imaging as well as what can be learned from their application to areas ranging from development to pathology.

B07 Bridging the Gap: Technologies and Methods for Correlative Light and Charged Particle Microscopy of Biological Systems

James A.J. Fitzpatrick, Matthew S. Joens, Joshua Z. Rappoport

Correlating light and charged particle (both electron, ion and x-ray) microscopy methodologies serves to bridge the multi-scale gap that hinders both the two- and three-dimensional analyses of rare cellular and sub-cellular level events that remain beyond reach due to the diffraction limit of light. The need to correlate information obtained from both types of datasets has proven a significant challenge, but has evolved in recent years with the advent of new probes, processing techniques, and detectors with substantially increased sensitivity. We seek to highlight the scientific innovations that address the correlation of light and charged particle microscopy of biological samples and soft materials. This symposium is intended to be a forum for the dissemination of correlative workflows and advanced sample preparation methods. Invited papers would include those describing novel approaches for correlating information from multiple light modalities with x-ray, electron and ion microscopy datasets. Of particular interest are innovative developments of new CLEM probes and contrast agents, advanced methods for ultrastructural preservation and dynamic in situ measurements. Target attendees will include engineers and scientists from all levels of bio-imaging expertise and all related backgrounds.

P03 Advanced Microscopy and Microanalysis of Complex Oxides

Xiaoqing Pan, Peng Wang, Elizabeth Dickey

Complex oxide materials exhibit a broad range of functional properties, such as high temperature superconductivity, metal-insulator transitions, colossal magnetoresistance, (anti-) ferromagnetism, (anti-) ferroelectricity, piezoelectricity, and multiferroicity. In many of these materials, unique functionality is derived from local structure and disorder, and there is a need to understand the interplay between chemistry, atomic structure and electronic structure at the atomic scale and across correlation lengths of tens to hundreds of nanometers. In addition, recent technical advances in the atomic-scale synthesis of oxide materials have provided a fertile new ground for creating fascinating phenomena and novel states of matter at their interfaces. A completely new class of electronic devices can be envisaged and engineered by tailoring the physical properties on the atomic scale. This symposium will focus on analytical transmission electron microscopy techniques, aberration-correction, spectroscopy, and in-situ methods to characterize these emerging properties across interfaces, thin films and bulk materials for the understanding of new phenomena that occur in these complex-oxide materials.

P06 Nanoparticles: Synthesis, Characterization, and Applications

Thomas W. Hansen, Abhaya Datye, Marc-George Willinger

Nanoparticles find a wide range of applications varying from food additives, medical applications as well as industrial catalysis. A broad array of techniques is utilized to study nanoparticles, but they tend to average information over a large collection of particles. Electron microscopy remains the most important technique since it provides information at the level of single particles. As the level of resolution has approached the atomic scale, with the wide spread deployment of aberration correction, we can do a lot more than determine particle size distributions.

In this symposium we aim at highlighting the properties of nanoparticles as determined from electron microscopy and related techniques. We seek contributions that highlight novel synthesis techniques to prepare nanoparticles, especially those that combine organic and inorganic materials. We will highlight the essential role of computational modelling through molecular dynamics simulations and density functional theory that help us in understanding the properties of nanoparticles.

Nikhilesh Chawla, James Evans, Jeff Gelb

Multiscale imaging aids in the understanding of how changes at each scale of interaction impacts whole systems. For material science applications, this can mean linking the atomic scale to bulk material or engineering scales. Whereas in biology it means placing macromolecular complexes and other subcellular components into a whole cell context or localizing single cells in a larger community, plant or animal scale context. Although each sample may have different temporal and spatial requirements, a common need exists to create hierarchical volumetric imaging data with increasing resolution or field-of-view under both static and in situ conditions in order to observe structural evolution (e.g. 4D). This symposia will bring together leaders in both materials science and biological fields for bridging scales in 2D, 3D and 4D microscopy using a variety of modalities alongside appropriate quantitative analysis techniques.

Sanjit Bhowmick, Andrew Minor, Daniel Kiener, Nan Li

Nanomechanical testing inside an electron microscope provides an opportunity for real-time imaging of the dynamics of deformation in materials at the micrometer, nanometer, and atomic scale. Recent advances in microscopy techniques, analytical detectors, high-speed cameras, and computing resources are able to provide unprecedented insights and fundamental understanding of elasticity, plasticity, fatigue, and fracture in nanostructured materials. The focus of this symposium is to bring the growing in-situ mechanical characterization community together to discuss key developments in techniques and experimental methods that aid in the understanding of deformation mechanisms of small-scale materials. Contributions on advanced mechanical characterization in controlled environments, which include elevated temperature, cryogenic temperature, electrical and magnetic fields, gas, and humidity, are particularly welcome.

A16 In situ and operando Characterization of Material Processes in Liquids and Gases

Raymond Unocic, Guangwen Zhou, Libor Kovarik

Within the past few years, in situ and operando electron microscopy has evolved to the point where high spatial and temporal resolution imaging, diffraction, and spectroscopy can be performed to elucidate the behavior of materials within liquid and gaseous environments either in response to external stimuli (in situ) or under a working condition (operando). This symposium intends to focus on the development of advanced techniques for in situ/operando experimentation and utilization of such techniques to study fundamental materials structure and chemistry, functional properties, dynamical behavior under non-equilibrium conditions, and materials synthesis/degradation. Understanding the effect of sample-beam interactions, which often limits the applicability of in situ TEM techniques, will also be of interest in this symposium. The symposium will focus on all aspects of imaging and analysis, covering imaging, diffraction and chemical analysis approaches available though in situ TEM.

Invited Speakers:

  • Eric Stach, Brookhaven National Laboratory
  • Thomas Hansen, Technical University of Denmark, Denmark
  • Ai Leen Koh, Stanford University
  • Haimei, Zheng, Lawrence Berkeley National Laboratory
  • Taylor Woehl, University of Maryland

A17 Biological Soft X-ray Tomography

Carolyn Larabell, Kenneth Fahy

This symposium is a forum for the exchange of information and knowledge on the use of soft X-ray tomography for imaging biological specimens. Soft X-ray tomography images fully hydrated, intact cells in 3D without the use of contrast agents or other visualization enabling molecules. Invited papers would include those describing technical advances in specimen preparation, data processing and reconstruction, imaging formation theory, and novel applications of the soft X-ray tomography in cell science. Target audience will include cell biologists, and scientists and engineers interested in novel microscopies, including correlative imaging methods.
