Brittle stars Featured 19 Sep 2003 Image

Brittle stars

Brittle stars. Colour of the brittle star Ophiocoma wendtii during the day (top) and at night. This marine echinoderm changes colour in response to light. It is covered in microscopic light-sensitive calcium carbonite crystals that act as microlenses, forming a compound eye on its surface. A network of nerve fibres beneath the lenses detects light signals, allowing the brittle star to detect and escape from predators. The design of the lenses may be used to improve components of optical networks and computer chips. The lenses were discovered by Joanna Aizenberg and her team at Lucent Technologies Bell Labs, USA

Computer graphic of a molecule of AMP

AMP. Computer graphic representation of a molecule of adenosine monophosphate (AMP). Atoms are depicted as spheres, joined by atomic bonds. Atoms are colour-coded: carbon (green), nitrogen (blue), oxygen (orange), phosphorus (yellow), hydrogen (white). The AMP molecule is a carrier of cell metabolic energy, and levels in the cell dictate rates of many biochemical pathways. This structure contains only one phosphate group (top right). When AMP gains two more phosphate groups it becomes ATP, the energy rich adenosine triphos- phate form. It now appears that many hormones exert their effect by first altering levels of AMP in the cell
