Emulsion photo of decay of kaon into pions Featured August Print

Emulsion photo of decay of kaon into pions

The first observation of the decay of a kaon into 3 pions, recorded in special photographic emulsion by Cecil Powell's team at Bristol University in 1948. The kaon produces the dense track coming in from top right. It decays at A into 3 pions. One of the pions moves away slowly, leaving a dense track, & then interacts at B. The other 2 pions are faster & leave relatively faint tracks as they move off in opposite directions towards top right & bottom left. (The distance between A & B is 25 micrometres). The kaon was the first discovered member of the family of "strange" particles, which contain a strange quark

False-colour TEM of Shigella sp. bacteria Featured August Print

False-colour TEM of Shigella sp. bacteria

False colour transmission electron micrograph of a group of the rod shaped bacteria, Shigella sp., a pathogenic strain causing bacillary dysentery. Dysentery, affecting mainly the large intestines, varies in severity from a mild attack of diarrhoea to an accute infection. Until the introduction of the sulphonamides in the 1930s it was a killer disease of the world. It still is among the young, elderly & malnourished. The infection is spread by flies, direct contact, & water contaminated by faeces containing the bacillus. The micrograph shows bacterial cell division (binary fission), a pinching in process which divides the cell in half. Magnification: X 13000 at 35mm size
