DUSSELDORF, Germany – Golden autumn sunlight breaking over the mighty Rhine was the pleasing sight for delegates taking a breather from the many sessions at the BIO-Europe Fall 2011 meeting, which opened at the Congress Center Dusseldorf Monday.But there was little time to savor the view. With 2,825 individual delegates representing 1,596 companies in attendance, and 183 company presentations scheduled here through Wednesday, the meeting does not allow much time for hanging around.
