Digestive decoys

Article Abstract:

James C. Paton and his colleagues at the University of Adelaide altered a harmless strain of Escherichia coli with the idea of bacterial toxins to bind to the decoy cells instead of to cells lining the human gut. Paton inserted genes from two other bacteria types into the mild-mannered Escherichia coli strain for constructing his decoys so that it would incorporate a chimeric molecule into its surface receptors.

Problems with contamination and genetic abnormalities may not stop work on embryonic stem cell therapies

Article Abstract:

A brief description on the problems with contamination and genetic abnormalities, which might not be stopped to work on embryonic stem cell therapies, is presented. Human embryonic cells grown in the laboratory are contaminated with material from supportive mouse cells in the cultures that makes their usefulness in future therapies questionable.

Attitude screen: Seeing if the public is ready for personal genetic information

Article Abstract:

The researchers at the U.S. National Human Genome Research Institute started research on the analysis of human DNA to explain individual genetic information. However, the Institute has to ascertain whether people would like to know their genetic capabilities or not.
