Hale-Bopp comet

Hale-Bopp. Artwork of the comet Hale-Bopp above an ocean shore. Hale-Bopp was one of the brightest comets of the 20th century, and was seen for much of early 1997. A comet is a lump of ice and rock. Its tail is formed as its ice evaporates as it nears the Sun. The tail always points away from the Sun, and may stretch for millions of kilometres


Naegleria fowleri protozoa, TEM Featured 17 Nov 2004 Image

Naegleria fowleri protozoa, TEM

Naegleria fowleri protozoan. Coloured transmission electron micrograph (TEM) of a section through a Naegleria fowleri protozoan. The nucleus (purple) contains a large nucleolus (orange), in which ribonucleic acid is synthesised. This organism is an opportunistic pathogen of humans, causing meningoencephalitis (inflammation of the brain and its surrounding membranes) when inhaled, often by children swimming in fresh water. Headaches, vomiting, sensory disturbance and a fatal coma may occur if the victim is not treated, often with a combination of antibiotics and anti-fungal drugs. Magnification: x3300 at 6x7cm size


Giant squid Featured 17 Nov 2004 Image

Giant squid

Giant squid (Architeuthis sp.). This sea creature has been the focus of myths and legends for more than two thousand years. Although this cephalopd mollusc does exist, what little is known about it has come from dead specimens that have washed up on shore or captured in nets by fishermen. The giant squid is the largest invertebrate animal in the world and amongst the most complex. It is a deep-ocean dweller, living at depths of 300-600 metres. It is thought to grow to between 17 and 20 metres. An adult has never been seen alive, although it may be possible to capture juveniles and maintain them in an aquarium in order to learn more about this creature's biology and habits
