End of magnet for Large Hadron Collider

Magnet for the Large Hadron Collider. The Large Hadron Collider (LHC) is the new accelerator for CERN, the European particle physics laboratory at Geneva. This is an end-on view of one of the cylindrical bending magnets. A test cable is seen inserted into one of the twin beam pipes down which bunches of protons or heavy ions will be accelerated in opposite directions at very close to the speed of light. The beam pipes are encased in a cryostat jacket which will be cooled to 1. 8 degrees Kelvin using liquid helium. This allows superconducting wire to be used, making possible the very strong magnetic fields needed to bend the proton beams around the LHC's 27-km circumference

Forensic DNA analysis

MODEL RELEASED. Forensic DNA analysis. Forensic scientist holding a vial containing DNA amplified from a trace amount found at a crime scene. The DNA is the cloudy strand at the base of the vial. DNA (deoxyribonucleic acid) is found in cells, and can be used as a genetic fingerprint to uniquely identify an individual. Modern procedures allow fast processing of samples and the results can be entered into databases with DNA details of many thousands of criminals and other individuals. DNA evidence is considered conclusive proof that a suspect was at a crime scene. DNA analysis can help solve old crimes and identify human remains. Tissues used include blood, saliva, skin and hair
