"There is no one centre with all the necessary experience or facilities to cope with the diagnosis of so many types of bone disorders," said project administrator Jacky Taylor, who is based at the National Genetics Reference Laboratory in Manchester.

"Until recently, we thought it was necessary to use visible light to produce oxygen through photosynthesis, but now we know there are at least three organisms that can do this using infrared radiation as well.

"Much like a seed is necessary for the growth of a plant, we believe that tumor stem cells exist at the heart of a tumor and perpetuate the growth of cancer," explained Dr. Donnenberg, who is assistant professor of surgery at the University of Pittsburgh School of Medicine.

Nanosphere's technology can rapidly, easily, and accurately interrogate both bases in the pair to determine if they are homozygous (i.e., both are mutant or normal) or heterozygous (i.e...... a fundamental understanding of landscape fires is necessary for comprehending the way much of the world works and for projecting the effects of changing human land use and climate on vegetation.
