Coloured SEM of Podocyrtis mitra, a radiolarian

Radiolarian. Coloured scanning electron micrograph (SEM) of the test (skeleton) of a Podocyrtis mitra, a type of radiolarian protozoan. Radiolarians build these hard, mineral skeletons around themselves as they float in warm seas with other plankton. They extend their protoplasm as pseudopodia (false feet) through pores in the shell to feed on tiny organisms. The radiolarians can change their density in order to vary their depth. Large numbers of radiolarian skeletons litter the sea bed; these become fossilised to form minerals like flint. Magnification: x190 at 5x7cm size. x460 at 6.75x4.7ins print

NMR scan of a childs head, sagittal section Featured 27 Aug 2003 Print

NMR scan of a childs head, sagittal section

Nuclear Magnetic Resonance (NMR) image of a sagittal (mid-profile) section through a child's head, showing structures of the brain and spinal cord. Details of the brain visible include the folds of the cerebral cortex, the cerebellum (below the rear lobes of the brain hemispheres) and the pons and medulla of the brainstem, the areas of swelling at the top of the spinal cord, which can be seen running down the neck. Unlike X- ray (CT) scanning, NMR imaging does not use ionising radiations; an image is obtained by studying the radio-response of protons in body tissues that are subjected to a strong, pulsed magnetic field
