Some inspirational advice for the new year:
The motivational part was written by a grad student, and the addendum added a week or so later by another student.
To explain the joke: iPS stands for induced pluripotent stem cells.
Meaning stem cells that have been created through engineering, by taking “regular” adult cells and moving them back to a more elastic state (aka a stem cell) where they can become any other kind of cell.
So iPS cells would indeed be the exception to the maxim that you can’t go back to the beginning 🙂
