Note that this is so potentially powerful because it's such a starkly different approach from the historical experiments that led us to this point. In the past, researchers basically worked in the opposite direction: some observable characteristic of the cell is tracked to the protein causing the observation, to the gene encoding the protein, to the specific pattern of activity that allows that gene to have that effect. In this case, researchers observe the activity patterns without context, then brute-analyze them to find other genes, with known effects. This allows them to work forwards toward practical effects on the cell, rather than backward from them.
