Pushing the thermal limits of nanoscale SQUIDs

Researchers have introduced a new type of nanoscale SQUID based on optimised proximity effect bilayers. This consists of a noble metal (Au) layer as a thermal shunt which is integrated with a variable-thickness superconducting (Ti) layer. The noble metal layer helps control the superconducting transition temperature and the degree of heating in the device via the so-called superconducting proximity effect.

Frozen magnetic monopoles create new laboratory physics

Many of the most interesting things in nature are transient, or far-from-equilibrium. To discover the secrets of far from equilibrium states, physicists need simple yet appealing laboratory systems. Now, researchers have created just such a system in the magnetic material known as 'spin ice'.

Nanotechnology tools: DNA clamp to grab cancer before it develops

As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology.
