X-Ray Stroboscope Offers New Insights Into Biomolecular Dynamics

Reaearchers from Göttingen in collaboration with colleagues from Augsburg have 'filmed' the movement of lipid molecules using an X-ray stroboscope at DESY. In the scientific journal Physical Review Letters, researchers lead by Professor Tim Salditt of the University of Göttingen report that their study offers new insights into the dynamics of biomolecules, which compose materials such as cell membranes. The cell membranes consist of a double layer of lipid molecules; the properties of the membranes are of great interest because they control which substances enter and exit a biological cell and also determine which materials are exchanged between different cell regions.

Highest Resolution Ever with X-Ray Microscopy

A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or "soft" X-rays to image structures only five nanometres in size. This resolution, obtained at Berkeley Lab´s Advanced Light Source (ALS), a DOE Office of Science User Facility, is the highest ever achieved with X-ray microscopy.

Raman Imaging: Seeing the Motion of Single Molecule in Real Time

UC Irvine chemists have scored a scientific first: capturing moving images of a single molecule as it vibrates, or "breathes," and shifts from one quantum state to another. The groundbreaking achievement, led by Ara Apkarian, professor of chemistry, and Eric Potma, associate professor of chemistry, opens a window into the strange realm of quantum mechanics - where nanoscopic bits of matter seemingly defy the logic of classical physics.

Intracellular Imaging Gets Interactive

A system of compounds has been developed that can signal the presence of certain chemical compounds critical to cellular energy metabolism, as well as activating them. The work demonstrates an approach that the authors suggest could be used to control or investigate cells. They describe their approach as ‘bioparallel chemistry', emphasising the contrast with widely known bioorthogonal chemical reactions that do not interfere with biological processes native to the cell.

Oxford Instruments Asylum Research Receives the 2014 Microscopy Today Innovation Award for ...

Oxford Instruments Asylum Research has received the 2014 Microscopy Today Innovation Award for the development of blueDrive Photothermal Excitation. blueDrive, an option available exclusively for Asylum's Cypher Atomic Force Microscopes (AFMs), makes tapping mode imaging remarkably simple, incredibly stable, and strikingly accurate. It replaces the conventional piezoacoustic excitation mechanism of the AFM cantilever by using a blue laser to directly excite the cantilever photothermally. more

Materials Science: Magnetism Intensified by Defects

Materials Science: Electron microscopy reveals how certain nanoscale crystal defects can dramatically intensify ferromagnetism in metal alloys. Magnetic materials are fundamental to many technologies, from data storage to next-generation spintronic devices. However, as integrated circuits become increasingly miniaturized and the sizes of magnetic components approach nanoscale dimensions, magnetic properties can disappear. Yasukazu Murakami and colleagues from the RIKEN Center for Emergent Matter Science and Tohoku University in Japan have now obtained important insight into the development of stable, strong nanomagnets, thanks to the discovery of amplified magnetization due to nanoscale atomic disorder in iron-aluminum alloys.
