  • Caption: Macrophage engulfing TB bacteria. Coloured scanning electron micrograph (SEM) of a macrophage white blood cell (red) engulfing a tuberculosis (Mycobacterium tuberculosis) bacterium (yellow). This process is called phagocytosis. Macrophages are cells of the body's immune system. They phagocytose and destroy pathogens, dead cells and cellular debris. Magnification: x750 when printed at 10 centimetres tall.
  • The inner surfaces of the iris and adjoining structures in the human eye
  • The cytoskeleton is made of strings of proteins that constantly stretch and shrink as the neuron sends out projections toward other neurons, making and breaking connections. This neuron is from mouse hippocampus, a part of the brain important in memory, but the ones in the human brain are constructed much the same way.

  • Cochlea from Inner Ear. Color-enhanced scanning electron micrograph of the inside of a guinea pig inner ear showing the hearing organ, or cochlea. Running along the spiral structure are rows of sensory cells which respond to different frequencies of sound. The whole organ is just a few millimeters long.
  • The venation network of a young quaking aspen leaf (Populus tremuloides) was magnified 4 times by Benjamin Blonder and David Elliott of the University of Arizona in Tucson utilizing a brightfield image of safranin-stained tissue. (Benjamin Blonder and David Elliott)

  • Morning glory flower pollination, SEM. Morning glory flower pollination. Coloured scanning electron micrograph (SEM) of pollen grains (orange) on the stigma of a morning glory flower (Ipomoea learii). The pollen grains, which contain male genetic material, have become trapped by the stigma's papillae (tiny projections, yellow). The stigma is part of the female reproductive structure (pistil), which is formed from one or more carpels.
