Stem cell advances
Once human cells differentiate it is very difficult to get them to revert back to their original totipotent or pluripotent state. This Science News article identifies that scientists think they have found a way (or have started to) to get human cells to revert back to an embyronic state. Do you think this is worthwhile research? Cancer was mentioned as an issue with transplanting these cells, why could cancer come from these cells?

The research is unique, and i am impressed by the way they take out the nucleus and replace it to make the process work. What I don't understand is, what would they use this technique for in patients? They kept mentioning that they could use this for patients, but never said exactly what they would use it for.
