And now for the next 50 years...

This year's annual meeting of the American Society for Cell Biology, the 50th, featured talks and displays marking the last 50 years in the field -- what scientists have learned, overturned, etc.

But tucked away into one part of the Philadelphia Convention Center was a much less polished, but equally interesting display -- a once-blank sheet of paper now filled with handwritten predictions from attendees of what the next 50 years in biology would bring.
