Brain tumour. Coloured scanning electron micrograph (SEM) of a glioma, a type of tumour that arises from glial cells of the central nervous system. The most common site for gliomas is the brain. They can be either low or high-grade, with the latter having the worse prognosis. Magnification: x8000 when printed at 10 centimetres wide. Credit: STEVE GSCHMEISSNER

Scanning electron micrograph (SEM) of cancellous (spongy) bone of the human shin. Bone tissue is either compact or cancellous. Compact bone usually makes up the exterior of the bone, while cancellous bone is found in the interior. Cancellous bone is characterised by a honeycomb arrangement of trabeculae. These structures help to provide support and strength. The spaces within this tissue normally contain bone marrow, a blood forming substance. Credit: SCIENCE SOURCE/SCIENCE PHOTO LIBRARY
