Nerve cell growth
Nerve cell growth. Fluorescent light micrograph of PC12 cells following stimulation by nerve growth factor. The cell bodies contain the nuclei (purple). The initially spherical cells have formed long branching extensions called neurites (grey and green). These neurites would form the axons and dendrons that connect nerve cells and transmit nerve impulses around the body, and the brain and spinal cord. PC12 cells are derived from a tumour of the adrenal gland (pheochromocytoma). Research into curing spinal paralysis uses nerve tissue cultures to investigate neural regeneration. Magnification: x670 when printed 10cm wide.

IBM 7090 computer in CERN
IBM 7090 computer (left) in the computercentre of CERN, 1963. In 1954 CERN, the Europeanparticle physics laboratory was founded in Geneva, Switzerland. Its work using high-energy particleaccelerators has led to many key discoveries inthe field of sub-atomic particles and high-energyphysics. The IBM 7090 was a transistorised versionthe earlier 709, which had been orientedspecifically towards scientific work. It wasintroduced in 1959 and used a 36-bit instructionformat, with a 3-bit prefix, 15-bit decrement, 3-bit tag and 15-bit address. It used floating-point arithmetic.
