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 ...

In a second step, this polarity is reversed using high-frequency impulses. This creates local magnetic markers in the fluid, which are detected in a third step by highly sensitive quantum sensors ...

Yeast cells aren’t normally magnetic, but a little genetic engineering can make them thralls to a magnetic ... a biomedical engineer who investigates the potential for magnetizing mammalian cells as a ...
