The technique involves using a mammogram or ultrasound scan to locate the tumour, and then implanting a tiny magnetic marker or ‘seed’. The aim is that this device will guide the surgeon to ...

Magnetic resonance imaging (MRI) is a non-invasive biomedical imaging technique that uses a strong oscillating magnetic field to induce endogenous atoms such as hydrogen, or exogenously added ...

Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...

Individuals’ metabolomic marker profiles may predict the onset of inflammatory bowel disease a decade in advance, underlining ...

The new blood-based assay PAC-MANN-1 (protease activity–based cancer marker using magnetic nanosensor-1) identified pancreatic ductal adenocarcinoma (PDAC) across all stages with high ...

This makes it easy both to hand-hold Big Larry or to pop him down on a flat surface (the base is also magnetic ... and looks rather like an oversized marker pen. It'll still go into your pocket ...
