Advanced MRI brain scan
Advanced MRI brain scan. This 3D magnetic resonance imaging (MRI) scan of a normal human brain has been produced by the 3T MRI scanner at Neurospin, one of the most advanced MRI research centres in the world. The front of the brain is at left. The coloured lines indicate the many neural pathways that exist in the brain. Neurospin has 3T and 7T scanners. The 'T' designations refer to the magnetic field strengths of 3 Tesla and 7 Tesla. These are extremely strong magnetic fields, and hence this technique is known as ultra high-field magnetic resonance imaging. The high magnetic field strength allows detailed examination of the brain and brain disorders. Neurospin was founded in 2006, and is located near Paris, France.

'In a British advanced observation post'
'In a British advanced observation post.' How artillery fire is observed and corrected. 'With the British Army on the Western Front' - published in 1916 for Tatler and Sphere. . Fortunino Matania, Ri (1881-1963). One of the most accomplished realistic illustrators and artists of his time, his wartime work was immensely popular and appeared in nearly every major news magazine, Allied, Neutral and Central Powers alike. Literally tens of millions of readers saw wartime events through the medium of Matania's weekly illustrations and, as such, he played an important role in defining people's mental image of what Great War battlefield scenes and soldiers looked like.

A British Advanced observation post
A ruined house is used as an advanced observation post by British officers. Situated close to German lines, the officers relay information back about the accuracy of artillery fire. The dark cloth seen behind one of the officers (with binoculars) helps to disguise any movement. Seen against a background of sky, he would inevitably attract the attention of snipers. Date: 1915
