The first nano-CT pictures of a bone sample with a diameter smaller than a human hair (about 25 micrometers).
Image explanation:
Clearly visible are cross-sections through the so-called osteocyte lacunae, i.e. cavities in which bone-sustaining cells (osteocytes) reside (colored in blue in the picture) and their fine interconnection network (canaliculi) of about 100 nanometers.
