Imagine what it was like to take a photograph of an object such as a tree, before the wide availablilty of zoom lenses. You would be able to make out the shape and the branches from a distance but you wouldnt be able to see the smaller branches or leaves. Until recently, Doctors have been in a similar situation regarding NMR (nuclear magnetic resonance) imaging of organs and other features deep within the body. Thanks to a new NMR microscope developed by Oxford Researchers, Doctors will in future be able to focus in with a magnification factor of around x100 on hot spots or areas identified as a potentially life threatening soft tissue disease such as cancer or an aneurysm in order to make a more reliable diagnosis in a more comfortable way for the patient.
The imaging of very small features within the human body using NMR has long been a desirable objective, not only because the images provided using current methods of PET (Positron Emission Tomography) scanning are not detailed enough i.e. they do not allow images of organs or other features deep within the body to be created in enough detail, but also because they involve the use of unpleasant processes such as injecting opaque dyes and time restricted large dose levels of X-rays.
Researchers at Oxford University have developed a waveguide technology which permits the detailed examination of features located at its tip. The tapered pickup allows the collection of very localised signals whilst isolating them from surrounding objects resulting in the possibility of collecting very high resolution MRI data.

Augsburg chemists and physicists report how they have succeeded in the extremely difficult separation of hydrogen and deuterium in a gas mixture.
Thanks to the Surface Acoustic Wave (SAW) technology developed here and already widely used, the University of Augsburg is internationally recognized as the...
Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.
In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...
Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
