BBC.The resolution of magnetic resonance imaging (MRI) has been given a massive boost by a team at computer giant IBM.
MRI is used as an imaging technique in medicine to visualise the internal structure of the human body.
The researchers demonstrated this imaging at a resolution 100 million times finer than current MRI.
The advance could lead to important medical applications and is powerful enough to see bacteria, viruses and proteins, say the researchers.
The researchers said it offered the ability to study complex 3D structures at the "nano" scale.
The step forward was made possible by a technique called magnetic resonance force microscopy (MRFM), which relies on detecting very small magnetic forces.
The big blue's R&D departments never cease to amaze.
