Just a pause to affirm that one doesn’t have to push the boundaries of ethics to extend the boundaries of medical science:

The cell identity switch turned ordinary pancreas cells into the rarer type that churns out insulin, essential for preventing diabetes. But its implications go beyond diabetes to a host of possibilities, scientists said.
It’s the second advance in about a year that suggests that doctors might be able to use a patient’s own cells to treat disease or injury without turning to stem cells taken from embryos.

Of course, some folks give the impression that, deep down, they believe that ethical absolutes are the greatest disease facing humanity, with all mere ailments as subsequent considerations.
