I'm late in getting something up on this, but it's big news:

In a move that will push the Methuselah Foundation's M Prize over the $1 million mark, Dr. William Haseltine, biotech pioneer of Human Genome Sciences fame, has joined the Three Hundred, a group of individuals who pledge to donate $1000 per year to the M Prize for the next 25 years. "I am delighted that my decision to join the Three Hundred has pushed the prize fund over its first one million dollars, which I trust is only the first of many millions," said Dr. Haseltine of his decision. "There's nothing to compare with this effort, and it has already contributed significantly to the awareness that regenerative medicine is a near term reality, not an IF."

Go, mousie, go!

Via our good friend Reason, of course.
