Comment: High-visibility vests – quality over cheap purchases

The latest ADAC test on high-visibility vests has yielded alarming results: 60 per cent of the models tested barely fulfil their purpose, if at all, and all of the failures come from the low-cost segment of the internet. This shows once again that the supposedly...

Magnetisation textures in graphene detected

Potential for security technology through nano-SQUID-on-tip sensors A team from the Weizmann Institute of Science in Rechovot has used a novel superconducting quantum sensor to visualise previously unknown magnetisation textures in rhombohedral graphene. Their...
