0.05 Tesla MRI: When less is more
A whole-body MRI scanner with a compact 0.05 Tesla permanent magnet has been developed that operates on a standard wall power outlet without radiofrequency or magnetic shielding cages.

Researchers were able to produce sub-millimetre resolution images of cardiac micro-vessels. This non-invasive new technique could allow scientists to study the physiology of the heart in more detail.
Research team led by Göttingen University combine two techniques to achieve isotropic super-resolution imaging.
Ever since the Abbe diffraction limit of conventional microscopy has been surpassed, super-resolution techniques have been diving ever deeper into the most miniscule details of molecular structures. We spoke with Prof. Dominic Zerulla, whose company PEARlabs is developing an imaging technique that sets out to push the boundaries once more – by looking at in-vivo nano-scale processes in motion.
Scientists use super-resolution microscopy to study previously undiscovered cellular worlds, revealing nanometer-scale details inside cells. This method revolutionized light microscopy and earned its inventors the 2014 Nobel Prize in Chemistry. In an international collaboration, AI researchers from Tübingen have now developed an algorithm that significantly accelerates this technology.
A new imaging technique has the potential to detect neurological disorders at their earliest stages, enabling physicians to diagnose and treat patients more quickly.
Monash University researchers have provided a fundamental advance regarding how T cells become activated when encountering pathogens such as viruses.
Using an ordinary light microscope, engineers at the Massachusetts Institute of Technology (MIT) have devised a technique for imaging biological samples with accuracy at the scale of 10 nanometers — which should enable them to image viruses and potentially even single biomolecules, the researchers say. The new technique builds on expansion microscopy, an approach that involves embedding…
Improving the detection of cancerous cells during surgery – this is the goal of the European research project CARMEN. The research institutes Laser Zentrum Hannover e.V. (LZH) from Germany and Multitel asbl from Belgium work together with companies from both countries, JenLab GmbH, Deltatec, and LaserSpec, to develop a novel, compact and multimodal imaging system. This could even allow the…
For the first time ever, expansion microscopy allows the imaging of even the finest details of cell membranes. This offers new insights into bacterial and viral infection processes.
Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as…
Scientists from EPFL have developed an algorithm that can determine whether a super-resolution microscope is operating at maximum resolution based on a single image. The method is compatible with all types of microscopes and could one day be a standard feature of automated models.
Ultra-high-field magnetic resonance tomography with field strength of 7 Tesla is slowly but surely entering clinical routine. ‘Thanks to very high spatial and spectral resolution, ultra-high-field MR permits detailed views of the human anatomy and can show precisely the metabolic processes such as those in the brain,’ said Professor Siegfried Trattnig, from Vienna’s Medical University.
Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart — a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death.
Light microscopy today offers a wealth of techniques that provide fascinating insights into life on subcellular level. “In light microscopy these days there are so many new techniques that each of us can only handle a subset of them,” says Christian Tischer, scientific officer in der Advanced Light Microscopy Facility of the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany,…
Scientists of the Göttingen Cluster of Excellence CNMPB and the EMBL describe efficient fluorescence tag for super-resolution microscopy.
A new type of super-resolution X-ray microscope invented by researchers from Paul Scherrer Institut (PSI) and Ecole Polytechnique Fédérale de Lausanne (EPFL) gives pin sharped insights into the composition of semiconductor devices and cellular structures.
