Total solar eclipse Featured September Print

Total solar eclipse

The large, shining corona of the Sun, seen during the total solar eclipse of 11 July 1991 from Baja Caifornia, Mexico. The visible corona is in fact the overlapping K-corona and F-corona. Usually it is only visible during eclipses, as the light from the Sun's photosphere drowns it out. The K-corona consists of fast-moving free electrons at a temperature of about 2 million Kelvin, at heights of about 75, 000km above the Sun's surface. The F- corona extends for many million km, and consists mainly of slow-moving particles of cosmic dust. The shape of the corona changes during the cycle of solar activity under the infuence of the Sun's magnetic field

F/col TEM of Corynebacterium diphtheria Featured September Print

F/col TEM of Corynebacterium diphtheria

False-colour transmission electron micrograph (TEM) of Corynebacterium diphtheria, showing a number of the Gram-positive, non-sporing, aerobic bacilli (rod-shaped bacteria) which are the causative agents of diphtheria. C. diphtheria is an obligate human parasite - man is its only natural host - causing an infection of the upper respiratory tract. Other effects arise from the production of an exotoxin which enters the bloodstream and damages the heart, nervous system, liver, kidneys and adrenal glands. The bacilli are slightly curved, and their appearance has earned them the name of "chinese characters". Mag: x13, 000 at 35mm size, x26, 000 at 6x7cm size
