You can poke them, prod them and pump them full of drugs, and they'll never complain, as New Scientist discovers IT STARTS out like any silicon chip: intricate patterns are drawn with light and etched with acid. But this is no microprocessor destined for a computer. Instead there are minuscule chambers filled with human cells: liver cells, lung cells, fat cells, all connected by tiny channels. A nutrient fluid is pumped through the channels, flowing from one chamber to another just as blood flows from organ to organ in the body. A company named Hurel (Human Relavent) is commecializing these so called animal on a chip technologies.
