MRI machine at the nanoscale breaks world records

The paper referenced is 'Probing the Nuclear Spin-Lattice Relaxation Time at the Nanoscale' [1] by researchers at the Leiden Institute of Physics.

One of the reasons this is interesting is the application to brain imaging - it is suggested it can be used to study the brains of Alzheimer's patients 'at a molecular level' which could pave the way for whole-brain scans and mapping.
