NeuroArm, a new weapon in surgery
Date: May 1, 2007
Author: David Bradley
A surgical robot that carries out its own MRI scans has been created by neurosurgeons in Canada. The system will liberate surgeons from the limitations of the human hand and could extend the working life of experienced surgeons way beyond the first signs of shakiness.

Unchained MRI
Date: Apr 1, 2007
Author: David Bradley
Physicists in Canada have used a conventional MRI system to control the movement of a small metal bead inside a blood vessel. The demonstration could herald the emergence of a new form of surgery that uses MRI to control "untethered" devices within the body.

The brain gain
Date: Jan 26, 2007
Author: David Bradley
US researchers used fMRI to probe brain activity associated with potential monetary gains and losses. They certain regions are more sensitive when you are heading for the red than when you are in the black, providing clues to how gambling addiction and other behavioural problems might be studied.
