Scientists at the University of Aberdeen have developed an ultra-low magnetic scanner, which can perform MRI scans without the need for intravenous contrast agents and with unprecedented precision.

Scientists use scanning tunneling microscopy to understand how a material's electronic or magnetic properties relate to its structure on the atomic scale. When using this technique, however, they can ...

The figure (left) shows the magnetic state above the surface by means of its (simplified) wave function (green wavy line), which penetrates beneath the graphene (dark grey small spheres) to the ...
