Friday beautiful science

Today's Friday beautiful science comes from the Nanotechnology Now art gallery at the University of Cambridge Department of Materials Science and Metallurgy:

The image shows the magnetic field lines in a single bacterial cell. The fine white lines are the magnetic field lines in the cell, which were measured using off-axis electron holography. Such bacteria live in sediments and bodies of water, and move parallel to geomagnetic field lines as a result of the torque exerted on their magnetosome chains by the earth's magnetic field.
