I think this is the biggest news since Dolly, and speaking of Dolly, there is a very obvious experiment that I'm sure somebody has thought of and already started. Take a gene for telomerase production and a gene to turn it on and insert them into a sheep cell. With present techniques when you insert a gene into a cell it almost never finds its way to the correct place on the chromosome and gets expressed properly. It may take millions or billions of attempts before everything works correctly, but you can put trillions of cells in a test tube and if you also include a signaling gene for antibiotic resistance or for the production of a small amount of florescent dye, you can find the one successful cell out of billions. Then you use that cell to make a clone and observe if you get a cancerous sheep, an immortal sheep, or no sheep at all. Whatever the results of this experiment it will give us a profound lesson in how life works. We live in exciting times.
