Oesophagus epithelium, SEM Featured 10 Mar 2004 Image

Oesophagus epithelium, SEM

Oesophagus epithelium. Coloured scanning electron micrograph (SEM) of the lining of the human oesophagus or gullet (yellow) and two unknown bacteria (pink & purple). The lining is composed of non-keratinised striated squamous epithelial cells, which have a surface covered in characteristic ridge-like folds (microplicae). Many types of bacteria are found throughout the alimentary canal. Rod-shaped varieties are known as bacilli, and ball-shaped varieties are known as cocci. The oesophagus is a muscular tube about 25 centimetres long that runs from the back of the throat to the stomach. Magnification: x 1700

Quantum entanglement equipment

Quantum physicists with equipment used in a quantum entanglement experiment. Entanglement is a property of a pair of particles in which a change to one has an instantaneous effect on the other, no matter how far apart they are. Researchers at Vienna University, Austria, split entangled photon pairs and sent each photon to a separate receiver. They performed this both in fibre optic wires and through the air. Entanglement was confirmed by the detectors in both cases. It is hoped that this entanglement will find uses in cryptography, quantum computing and satellite communications. Photographed in 2003. The double exposure effect illustrates the oddness of the quantum world
