• Tandem mass spectrometry (GC-MS/MS) is an alternative to GC-HRMS
  The Revision of EU Regulation laying down methods of sampling and analysis for the control of levels of dioxins (PCDD/Fs), dioxin-like and non-dioxin-like PCBs in foodstuffs allows GC-MS/MS in addi...
• A new way to assemble individual molecules could revolutionize the creation of novel materials
  This work focuses on the interactions between molecules and in particular on "amphiphilic" molecules, which contain two distinct parts to them. Household detergent is a good example of a product th...
• Sucessful determination of the state of a quantum mechanical system
  Processes on the atomic scale can only be described accurately by using the laws of quantum mechanics. Physicists at the University of Würzburg have now succeeded for the first time to completely d...
• Nano-imaging probes molecular disorder
  Using a newly developed imaging method, LMU researchers show that thin-film organic semiconductors contain regions of structural disorder that could inhibit the transport of charge and limit the ef...
• Three-dimensional volume diffraction optics for X-rays developed
  Physicists at HZB have developed a process to generate improved lenses for X-ray microscopy that provide both better resolution and higher throughput. To accomplish this, they fabricate three-dimen...
• Observing the random diffusion of missing atoms in graphene
  Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging n...
• Nanodiamonds identified as potent bactericidal agent
  Exhibiting a diameter of 5 nanometers, nanodiamonds are 200-times smaller than a bacterium. Nanodiamonds are produced by the explosion of carbon-containing compounds in high-pressure storage tanks....
• High resolution in tomography with hard X-rays
  Tomography enables the interior of a vast range of objects to be depicted in 3D - from cellular structures to technical appliances. Researchers from the Paul Scherrer Institut (PSI) have now devise...
• Bacteria can reshape their DNA to survive dehydration
  The research shows that bacterial DNA can change from the regular double helix - known as B-DNA, to the more compact A-DNA form, when faced with hostile conditions such as dehydration. Crucially...
• OpenFDA to provide easy access to valuable FDA public data
  The U.S. Food and Drug Administration launched openFDA, a new initiative designed to make it easier for web developers, researchers, and the public to access large, important public health datasets...
• First 3D Model of a Synapse
  A glance into a new world for neuroscience: research team from Göttingen led by Prof. Dr. Silvio O. Rizzoli present the first scientifically accurate 3D model of a synapse. This effort has been mad...
• DNA-coralling protein complex in an unexpected bind
  Every time a cell divides to create two offspring cells, it has to carefully manage its genetic inheritance to ensure that each new cell ends up with their appropriate share. In most cases, the par...
• A new way to analyse delicate biomolecules
  Using DESY's synchrotron light source PETRA III, scientists have pioneered a new way to analyse delicate biomolecules. The novel approach, borrowed from a new class of high-intensity X-ray sources ...
• X-ray pulses on demand from Electron Storage Rings
  HZB physicists recently devised a new method to pick single x-ray pulses out of the pulse trains usually emitted from synchrotron radiation facilities. The technique is very useful to support studi...
• Nano World: Where towers construct themselves
  Imagine a tower builds itself into the desired structure only by choosing the appropriate bricks. Absurd - and however, in the nano world this is reality: There an unordered crowd of components can...
• Immunologists discover immune system precursor cells that fight infection
  The innate immune system recognizes infectious agents such as viruses and bacteria. A group of lymphocytes known as "innate lymphoid cells" or ILCs plays a central role in the defense of the human ...
• Better catalysts for the petrochemical industry
  When crude oil is refined to fuels and chemicals, help is at hand - in the form of so-called catalysts. Scientists now provide a reference parameter for the performance of an important class of cat...
• New insight into photosynthesis
  The way that algae and plants respond to light has been reinterpreted based on results from experiments studying real-time structural changes in green algae. Under particular lighting conditions du...
• Diverging thermal conductivity
  Physicists at the Max Planck Institute for Polymer Research show unlimited heat conduction in graphene. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the Natio...
