Researchers at NIH-FEI Living Lab for Structural Biology achieve breakthrough biological results

FEI is pleased to announce that researchers at the NIH-FEI Living Lab for Structural Biology have achieved breakthrough biological results, using FEI’s Titan Krios™ transmission electron microscope (TEM), to elucidate the structural mechanism by which glutamate receptors participate in the transmission of signals between neurons in the brain. Their work is described in Nature, “Structural Mechanism of Glutamate Receptor Activation and Desensitization,” by Meyerson, et al., (DOI: 10.1038/nature13603), http://www.nature.com/nature/journal/vaop/ncurrent/full/nature13603.html .

Study finds microglia increase neuronal firing and enhance brain cell survival after injury

A type of immune cell widely believed to exacerbate chronic adult brain diseases, such as Alzheimer's disease and multiple sclerosis (MS), can actually protect the brain from traumatic brain injury (TBI) and may slow the progression of neurodegenerative diseases, according to Cleveland Clinic research published today in the online journal Nature Communications.

FEI announces the sale of a complete correlative workflow to the University of Maastricht

FEI (NASDAQ: FEIC) announces the sale of a complete correlative workflow to the University of Maastricht. The systems will be installed at the University’s Institute of Nanoscopy, a new research facility that will use the high-resolution microscopes to understand the working mechanisms of protein complexes in an effort to develop new and improved treatment and prevention for disease, such as cancer and tuberculosis.

Novel microscopy technology helps detect protein that plays key role in prostate cancer

Assemblies of proteins, known as protein complexes, have important functions in cells; protein complexes embedded in the cell membrane, for example, are responsible for the exchange with the extracellular environment.

Researchers study structural aspects of DNA-particle/lipid interface directly using x-ray scattering

Scientists seeking ways to engineer the assembly of tiny particles measuring just billionths of a meter have achieved a new first-the formation of a single layer of nanoparticles on a liquid surface where the properties of the layer can be easily switched.

Dendrimer offers a simple way of creating vesicles

One of the defining features of cells is their membranes. Each cell's repository of DNA and protein-making machinery must be kept stable and secure from invaders and toxins. Scientists have attempted to replicate these properties, but, despite decades of research, even the most basic membrane structures, known as vesicles, still face many problems when made in the lab. They are difficult to make at consistent sizes and lack the stability of their biological counterparts.
