The interior single cell in the brain, freeze fractured to reveal its organelles and imaged with a scanning electron microscope.  The nucleus is purple, DNA is pink, endoplasmic reticulum is green, ribosomes are blue, golgi apparatus is olive, vesicles are yellow, and mitochondria are red.  This image is part of a 600 megapixel mosaic, which can be seen in full resolution on gigapan.  The sample was prepared with the osmium maceration technique by Dr. Patrick Nahirney

Pollen from a forget-me-not. This flower has one of the smallest known grains of pollen; just five one-thousandths of a millimetre in diameter. A Swiss scientists named Martin Oeggerli, who uses the name Micronaut for his art, has captured these Scanning Electron Microscope images of pollen grains.
