Integral membrane proteins also are notoriously hard to synthesize and study, which explains why so few have been fully, three-dimensionally characterized with protein crystallography. Using standard recombinant DNA techniques and some novel design principles, Cornell chemical engineers have developed a new method for making large quantities of integral membrane proteins simply and inexpensively – all without the use of harsh chemicals, or detergents, typically used today.

Undergraduates will model “Irradiance” – a collection of electrogarments designed by Eric Beaudette ’16, fiber science; Lina Sanchez Botero, graduate student in the field of fiber science; and Neal Reynolds, graduate student in the field of physics – on the runway at the Cornell Fashion Collective, Saturday, April 11, at 8 p.m. at Barton Hall.

Although the desire to streamline was paramount along with a responsive display that works across multiple devices, we wanted to visually highlight our users and scientists in action at the lab and sprinkle their news articles across the site. We chose a CMS platform, Drupal 8, which in addition to those and many other engaging digital experience features, allows for accessible content entry. The results of the project were revealed last month.

The project director Lora Hine is manager of Xraise, the education and public outreach program at CHESS. Xraise will be working in collaboration with the principal of the Beverly J. Martin (BJM) Elementary School and the second/third grade teacher teams at BJM Elementary School, part of the Ithaca City School District.

Drs. Turner and Shade lead the experimental and modeling components of the high-energy diffraction microscopy team. The effort continues to develop novel, high quality, and world-first datasets to validate micromechanical models with the longer-term goal of advancing microstructure-based component lifetime predictions for aerospace alloy systems.

One of her research specialties is using two-dimensional high-resolution elemental maps of small sections of fish ear stones, called otoliths, as time-stamped records of the histories of fishes’ lives and marine conditions. Her studies have challenged many CHESS scientists over the years to further develop scanning x-ray fluorescence microscopy (SXFM) at the F3 station, including Don Bilderback and Rong Huang who produced microbeams with tapered glass capillaries and Darren Dale who built software for rapid data collection, analysis and visualization of elemental maps (1,2).

Like many other bacteria, Rickettsia uses the actin cytoskeleton of the host cells to move within a cell and spread from one cell to another. It does this through the agency of a “comet tail” assembled from actin filaments, and inhibition of comet tail formation reduces the virulence of Rickettsia. The bacterial transporter protein Sca2 is required for assembly of comet tails; it functions similarly to the eukaryotic formin proteins in promoting actin filament formation.

These devices create position information based on photo-electron currents produced by X-rays hitting metallic blades that usually skim the outer edges of beam. Typical P.E. monitors for undulator source utilize four blades to determine simultaneously both vertical and horizontal position information by taking mathematical difference-over-sum (D/S) values using photo currents from opposing blades.

These bismuth platinum pyrochlore films have potential for use in fuel cells, where they could act as more effective cathode materials. Using pulsed laser deposition (PLD) at the G3 beamline of CHESS to co-deposit epitaxial δ-Bi₂O₃ and disordered platinum, the team was able to produce epitaxial Bi₂Pt₂O₇ crystals approximately 100 nanometers in length by annealing the PLD deposited films in air.

Students in BJM's not-for-profit extended day program, Academic Plus, were given some basic tools, access to common materials, and assignments like, "Make something roll from here to there." They dove head-first into the challenge, limited only by the extent of their creativity and what's physically possible.
