There was that report I think earlier this year about a team of Scottish researchers who'd, IIRC, reprogrammed t-cells to attack only cancer cells and cured cancer in mice. Have there been any new developments on that?

I did a quick search and there lots of articles and research papers on the programmed T cells that have been released in the past month.  You should check them out.

I did the search and it seems like this approach of programming T cells was already in use in fighting cancer before the big announcement from the Scottish team. So what did those guys exactly innovate and does this has prospects of being a cure or just a therapy?
