Mock-up of Large Hadron Collider at CERN Featured 15 Mar 2004 Image

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 Featured 15 Mar 2004 Image

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

Polarised LM of streptomycin crystals Featured 15 Mar 2004 Image

Polarised LM of streptomycin crystals

Streptomycin. Polarised light micrograph of crystals of the antibiotic drug streptomycin. This is an aminoglycoside type of antibiotic, a drug used to treat infections caused by bacteria. Streptomycin was discovered in the 1940s and was the first effective drug treatment for tubercu- losis (TB). It is still used to treat resistant strains of bacteria causing TB, but because of serious side-effects streptomycin has largely been replaced by other antibiotics. Streptomycin is, however, still used to treat uncommon infections such as plague, brucellosis, and glanders. It may be used with penicillin to treat endocarditis. Magnification: x25 at 35mm size
