One of the hottest areas of biology today is synthetic biology. Synthetic biologists are not content to take a gene from one species and insert it into the genetic material of another species.Instead, synthetic biologists are attempting to build a set of standard building blocks often by synthesizing DNA from scratch. The idea is to have a set of modules that can be plugged together to make the biological equivalent of electrical devices.So just as an electrical engineer designs new circuits by plugging together standard parts on a breadboard, the synthetic biologist attempts to create custom organisms by inserting these biological circuits into cells.The field has progressed to the point where there is an annual student competition at MIT dedicated to designing custom devices called iGEM which stands for InternationalGenetically Engineered Machine Competition. The winners of the 2007 competition have just been announced and they include teams that developed applications of synthetic biology to medicine, environmental sensing, energy and information processing.For example a team from Alberta Canada developed a synthetic set of genes involved in the production of butanol, an organic compound that could serve as a fuel alternative to ethanol.A team from University of Missouri at Rolla, the Missouri Miners developed a biological breathalyser and a biological timer.Synthetic biology is in its infancy and the power of this technology is rapidly increasing, much like the power of computers, so that soon synthetic biologists may be able to construct synthetic organisms entirely from scratch!Readers, how is this dangerous in a positive sense? How about the risks?LinksSyntheticbiology.orgSynthetic Life, Scientific American 2004

It seems both tantalizing and frightening at the same time. As with much progress, both good and evil could follow due to its use or misuse. I remember watching a movie many years ago called "Creator" with Peter O'Toole and Mariel Hemingway in which O'Toole's character saves DNA from his dead wife with the hope of cloning her. Although the science may have been improbable, it made for some interesting discussions and thoughts about relationships and holding onto the past..
