Broadclub cuttlefish

Male broadclub cuttlefish (Sepia latimanus) displaying threat colouration to another male (not seen). The bands of black and white are used to intimidate other males during the breeding season. Cuttlefish can rapidly change the colour of their skin by dilating or contracting pigment cells called chromatophores. This cuttlefish preys largely on crustaceans, which it catches with a quick strike with its two tentacles (not seen). These are usually kept hidden amongst its eight arms, as here. This cuttlefish is found in the tropical Indo-Pacific region. It may reach a length of around 45 centimetres. Photographed off Indonesia

The Grid

The Grid. Computer artwork representing The Grid, a network of supercomputers that will allow access to their processing power from a standard desktop computer. The Grid operates in a similar way to the internet, but instead of simply sharing documents and data it can share system resources. A user on a computer in one part of the world can use the network of supercomputers to perform calculations far beyond the capabilities of the computer through which it is accessed. Problems in particle physics, medicine, astronomy, engineering and many other fields can then be solved without leaving the laboratory
