Mapping Bacterial Membrane Proteins with Super-Resolution Microscopy

Using super-resolution microscopy researchers have found another chink in bacteria's armour, mapping for the first time the structure of a protein that plays an important role helping infection gain a foothold in the body. Published in Nature a group of international scientists from Monash University, the National Institutes of Health (NIH), the Georgia Institutes of Technology and the Diamond Light Source have determined the structure, in two species of bacteria, of an essential membrane protein called BamA.

Amplifying the Sensitivity of Raman Spectroscopy Using Carbon Nanotubes Probes

Using carbon nanotubes, a research team led by Professor Hyung Gyu Park in collaboration with Dr. Tiziana Bond has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy. This type of sensor makes it possible to detect molecules present in the tiniest of concentrations.

Materials Research: First Laser-like X-ray Light from a Solid

Researchers have for the first time created an X-ray laser based on a solid. The method developed at DESY's free-electron laser FLASH opens up new avenues of investigation in materials research, as reported by the team of Prof. Alexander Föhlisch of the Helmholtz Zentrum Berlin (HZB) in the journal Nature. "This technology makes it possible to analyse sensitive samples that otherwise are quickly destroyed by intense X-ray light," notes co-author Prof. Wilfried Wurth of the University of Hamburg and the Hamburg Center for Free-Electron Laser Science (CFEL), a collaborative effort by DESY, the Max Planck Society and the University of Hamburg.

3D NanoChemiscope: Combining Microscopy with Mass Spectrometry for Surface Analysis

The 3D NanoChemiscope is a miracle of state-of-the-art analysis technology. As a further development of well-known microscopic and mass spectroscopic methods, it maps the physical and chemical surfaces of materials down to the atomic level. This instrument, which is unique in the world, not only delivers high-definition images; it also knows what it is "seeing".

Improving Optical Sensing with a New Silver Nanoantenna-Superlens System

Mathematical modeling confirms that a nanometer-scale device that can concentrate light into a tiny spot improves optical sensing. Conventional lenses, made of shaped glass, are limited in how precisely they can redirect beams of incoming light and make them meet at a point. Now, a team led by Zhengtong Liu at the A*STAR Institute of High Performance Computing, Singapore, has proposed a novel approach to ‘superlens' systems that can surpass this classical limit of focusing light.

Correlative Microscopy: Specialized Endocytocis Consumes Membrane Tendrils

The process cells use to ‘swallow' up nutrients, hormones and other signals from their environment - called endocytosis - can play a crucial role in shaping the cells themselves, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have found. The study, published in Nature Communications, could help explain how the cells on your skin become different from those that line your stomach or intestine.

Arizona State University: Electron Microscopy of Carbon Under Pressure

High pressures and temperatures cause materials to exhibit unusual properties, some of which can be special. Understanding such new properties is important for developing new materials for desired industrial uses and also for understanding the interior of Earth, where everything is hot and squeezed.
