Dolly's Creator Moves Away from ESC to iPS.

Yamanaka's ability to convert adult mouse cells into embryoniclike stem cells—called induced pluripotent stem cells (iPS cells)—has pumped fresh excitement into regenerative medicine. In this process, scientists use viruses to deliver three to four genes into an adult cell and to reprogram it back to its unspecialized state, enabling it to grow into any type of cell in the body. In a span of months, Yamanaka's team and three others reported success using human cells from adult skin and joint tissue and newborn foreskin.

What's this?
Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

Now the 64-year-old Wilmut is one of several high-profile scientists who remain loyal to SCNT [somatic cell nuclear transfer] in concept but are leading a wholesale charge out of the field and into an alternative technology. That other approach, first demonstrated in 2006 by Shinya Yamanaka of Kyoto University, restores adult cells back to an embryonic­like state called pluripotency, in which they regain the ability to develop into any kind of cell.

Fascinating, and promising.
