The Time Is (Still) Right

Michael White at Adaptive Complexity promises to say something nice about systems biologists soon, but first he writes that the field is "still struggling to get beyond square 1." On his blog, he includes two passages, one from 1976 and one from 2005, that both say the time is right to take an integrated look at biology. "We're saying the same things now that we were saying 30 years ago: the time is ripe, we need a systems-level understanding, it will revolutionize biology. And yet there is still so little consensus about how to do it," White writes.
