microscope to allow researchers to overlay chemical and physical images. It opens up a whole world of studies, Nealson said. You can use this technology to look at things going on inside the cell. This is going to change the way that we do a lot of...
Boffins Find Evidence for Novel Brain Cell Communication
...nd crabs). The current study provides the first electron
microscopic evidence for gap junctions on the axons of excitatory nerve cells in the mammalian brain. Gap junctions at this site, on axons, would be expected to act as short circuits for nerve signals and to produce cross-talk. However the new dat...

Bubbles may Pave Way for Producing Nanoscale Electronic Components
...examined the resulting film under both optical and electron
microscopes, and found that the nanowires and nanotubes had become neatly lined up vertically towards the top of the bubble and evenly spread out across the surface. Varying the concentration of tubes or wires in the mixture altered the density of ...

A Sweet Step Toward New Cancer Therapies
...at problem, researchers have used a process called electron
capture dissociation (ECD) instead of the usual "shake-it-til-it breaks" method to fragment proteins. But that method requires the presence of at least two positive charges, which can be difficult to accomplish with acidic molecules, such as proteins...
Natural Milk Protein Could Lead to Super Nutritious Foods
... Engineering also took part in the research, using electron
microscopy to visualize the tiny micelles, which measure in at a miniscule 150 nanometers (0.00015 millimeter). Dr. Livney says that foods utilizing this technology could reach the marketplace within five years. The researchers are now studying whe...
Potentially Pathogenic Virus Found in Mad Cow Cells
... 'mad cow' disease. Examining the cultures using electron
microscopy, Manuelidis and her co-authors found an abundance of 25 nm virus-like particles. They also found that the particles did not bind antibodies for the prion protein, indicating they were not composed of prion protein. The development of the p...
