Cryo-electron microscopy images shed light on virus structure, function UCLA researchers report in the April 30 edition of the journal Cell that they have imaged a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of imaging biological complexes at such a resolution. The research team, led by Hong Zhou, UCLA professor of microbiology, immunology and molecular genetics, used cryo-electron microscopy to image the structure at 3.3 angstroms. An...

X-ray diffraction microscopy provides the best resolution yet A team of scientists working at beamline 9.0.1 of the Advanced Light Source (ALS) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory has used x-ray diffraction microscopy to make images of whole yeast cells, achieving the highest resolution"”11 to 13 nanometers (billionths of a meter)"”ever obtained with this method for biological specimens. Their success indicates that full 3-D tomography of whole...

In nanoscience, researchers are truly limited by the technology of their field, needing increasingly more advanced tools for studying, analyzing and manipulating objects and systems at the scale of individual molecules and atoms. Directors of the Kavli Institute at Cornell for Nanoscale Science, Paul McEuen and  David A. Muller, talk about their mission to push the technology of observation, measurement and control to ever-smaller dimensions. To expand the boundaries of nanoscience, the...

ORNL Z-contrast microscope first to resolve, identify individual light atoms OAK RIDGE, Tenn. -- Using the latest in aberration-corrected electron microscopy, researchers at the Department of Energy's Oak Ridge National Laboratory and their colleagues have obtained the first images that distinguish individual light atoms such as boron, carbon, nitrogen and oxygen. The ORNL images were obtained with a Z-contrast scanning transmission electron microscope (STEM). Individual atoms of carbon,...

Material scientists have high hopes that one day they will be able place a sample of unknown substance under a microscope and be able to name individual atoms and what structure they form, reports the AFP news agency. Thanks to a feat by US scientists, they are one step closer to that goal. Scientists used a transmission electron microscope to analyze a single layer of film made up of boron nitride. They were able to distinguish boron atoms from nitrogen atoms, as well as oxygen and carbon...

It's been used to dye the Chicago River green on St. Patrick's Day. It's been used to find latent blood stains at crime scenes. And now researchers at Northwestern University have used it to examine the thinnest material in the world. The useful tool is the dye fluorescein, and Jiaxing Huang, assistant professor of materials science and engineering at the McCormick School of Engineering and Applied Science, and his research group have used the dye to create a new imaging technique to view...
