Mock-up of Large Hadron Collider at CERN

Mock-up of the Large Hadron Collider. The Large Hadron Collider (LHC) is the proposed new accelerator for the CERN European particle physics laboratory. The magnets for the LHC (seen here in blue) will sit on top of the existing Large Electron-Positron (LEP) accelerator at CERN's Geneva site. The LEP occupies a tunnel some 27km in circumference. Advances in magnet design mean that the LHC will be able to bend beams of protons and heavy ions around the same curvature as the far lighter electrons used in LEP. This will create far higher collision energies than the existing LEP ring, allowing scientists to delve even further into sub-atomic processes

Coloured SEM of internal membrane of hen eggshell

Eggshell membrane. Coloured scanning electron micrograph (SEM) of the internal membrane from the shell of a hen's egg. Several membranes are found around the embryo in a bird's egg. The shell membranes adhere to the inner surface of the shell, with an air space between them at one end of the egg. Changes in the eggshell as the chick develops permit the passage of carbon dioxide and oxygen and the release of water vapour via the shell membranes. The function of the membranes and the shell is to protect the developing chick from trauma and dessication. Magnification: x1500 at 5x7cm size. x5200 at 10x8ins
