Why?
Have you
ever wondered why biology is so much better at its job than we are
at ours? What does it
get right that we don’t? The answer may surprise you. It
has learned how to gather, use, and interpret information correctly. This
is the lesson we can now learn from an information infrastructure. Allow
me to explain.
We as
investigators explore biology by devising models to supply and
interpret biological information that comes to us in the form of
data. Biology continues to outperform us because it already knows
how to match all of its models (rules) to its information (data).
We arrive at the playing field with two principal shortcomings.
First we fail to understand that our primary role is that of an
observer and second we are genuinely inept at matching our models to
our data.
Our
goal here is quite straightforward. We – as players - want to
become just as skillful as biology at playing the game. Exactly, what
game is biology playing? It uses a vast collection of
parts and its remarkable engineering skills to assemble complexities
with advantageous properties. As a complex adaptive system, it
continually upgrades or creates new complexities as the need
arises. In effect, biology seems to be playing a
complexity-emergent properties game. If true, then we - as
researchers – can profit by learning to play this game as well.
Although biological stereology - supported with advanced
technologies - is rapidly learning how to play this game, the big
players will ultimately be biochemistry and molecular biology,
largely because of their ability to generate vast quantities of
research data.
There
is, however, a small problem. These molecular disciplines have allowed
themselves - unwittingly - to become caught in a catch-22. They are
producing huge amounts of semiquantitative data that
bear little if any resemblance to the quantitative data of biology.
As accurate descriptors or predictors of biology, semiquantitative and
quantitative data tend to be mutually exclusive. Since our
new model model for systems biology
(SB2) includes molecular data, their shortcomings become ours as well.
This means that before we can tap into the molecular data of these
disciplines, we have to find a way to release the catch-22.
Consider
this. Can we bring biochemistry and molecular biology
into the game by leveraging what we are learning about biological
complexity with our stereological data? Yes, I think so. The new
connection phenotypes offer the promise of turning semiquantitative
data into quantitative data – provided the sampling is unbiased.
Recall that genes control both the amounts and the proportions of
the parts they produce. Since connection phenotypes can extract quantitative
proportions from semiquantitative data, we can at least bring biochemistry and molecular
biology into the game as minor players. To become major
players, however, someone will have to figure out how to estimate
unbiased counts of molecules in an in vivo setting with
hierarchical connections.
