Researchers in NY created the first genetically modified human embryo by inserting a gene for a florescent protein:

After the embryo divided for three days, all the cells in the embryo glowed, Dr. Rosenwaks said. He said the goal of the work was to see if the fluorescent marker would carry into the daughter cells, allowing genetic changes to be traced as cells divided.

I don’t know or care what practical purpose an experiment like this could ever serve, it is disturbing to see human life treated as nothing more than an instrument of scientific experimentation.
