o    "The middle - going from hits and leads to drugs with proof of concept - is
     where industry fails. There, you need agility, focus and speed. You need
     autonomy and accountable entrepreneurial spirit that maximises scientific
     interaction and internal competition for resources.

o    .... These units, of no more than 400-500 scientists, will work on the drug
     leads that have been discovered in the huge screening processes conducted
     at corporate level."
