That's an interesting idea and I think we're getting closer to
it, though I think we still have a long, long way to go even to
simulate the behavior of a single cell.
The Stanford "Folding@home" project attempts to simulate the
folding of polypeptides (strings of amino acids) into proteins.
It takes thousands of hours of computer time to just figure out
the most likely scenario for how one protein folds from a linear
sequence of amino acids into "secondary" and "tertiary"
structures that actually do work in the cell. Since a typical
cell may have tens of thousands of proteins, not to mention other
molecules, and since they assemble into a huge variety of
structures about which we still have only limited knowledge, I
suspect we're still decades away from full simulations.
But, like everything in science, progress measured from month to
month and even from year to year, appears slow. But when we look
back over a few decades or more, the total progress is truly
astonishing.
It's incredible to think that our grandfathers were born in the
horse and buggy era. Their parents lit their homes with candles
and oil lamps. Radio was a revolution in our parents generation
and many of us can still remember when television came into our
homes for the first time. My own children can remember when the
first computers came into our home.
DNA, in many ways the foundation of life, was not understood
until the 1950's, and now we know that it is mutations in DNA
that are the cause of cancer.

The work I do is all information dissemination rather than
scientific programming. I work on the system that prepares the
data that goes onto
http://www.cancer.gov.
However, I've gotten interested in the science behind it all and
try to read books on biology and chemistry. I'm slowly becoming
more knowledgeable.

The drug companies spend much more on advertising, marketing, and
lobbying than they do on research. A good part of that money is
dedicated to convincing people, voters and government officials,
that they are spending more money on research than on
advertising.
Nowadays, the drug companies spend even less money on research
than they did, say, ten years ago. The new model of drug company
drug discovery is:
Get in bed with universities, medical schools, and biotech
startup companies.
Let those organizations fund their own research by getting
government research grants and some venture capital.
If, and only if, truly promising research comes out, wave big
bucks at the professors and buy out the biotechs to get the
marketing rights.
The idea is, don't ever spend money on basic research. Let the
government do that. Buy the fruits of the research when you
already know it's likely to pan out.
So the taxpayer funds the research. If it fails, the taxpayer is
out the money. If it succeeds, the drug company buys the rights,
the government gets nothing, and the taxpayer is not only out the
money but must also pay for the huge profits that the companies
make in order to get the drugs that their taxes paid to develop.
I won't say that the drug companies never invest money in
research. They do invest some. But the amounts have been
declining in the last decade.
Do I sound bitter about that?
In my view the drug companies, by sucking the money out of the
health system, are one of the major obstacles to progress.
There are others, of course, who disagree. And even I do believe
that the typical scientist and technician working at a drug
company is sincere in his or her attempt to advance science and
health. But the organization is, after all, not dedicated either
to science or health. It's dedicated to making profits for the
stockholders. The two interests do not coincide, and where they
conflict, there's no question about which interest wins.

In a way, NCI does attempt to do that.
They have a team of people who read every single article
published in the top 200 or so medical and cancer journals, in
every issue.
If someone reading an article thinks it may be significant, they
xerox it and send it out to one of the board members for his
review. He reads it and, if he (or she) thinks it's good he says
so and it will be sent out to two more board members for their
review. One of the people will volunteer or be appointed to make
a presentation to the board as a whole.
The board meets about 5 or 6 times per year, the people coming in
to Rockville, Maryland, or appearing by video conference. At the
meeting they thrash out all of the research that they think is
significant since their last meeting.
As a result of their discussions, they might do any of the
following:
Edit the state-of-the-art summary that NCI publishes for each
type of cancer, revising NCI's recommendations to cancer
practitioners. Over 500 such summaries are maintained on a
regular basis.
Add articles to the recommended bibliography that they urge
oncologists to read.
Make recommendations to NCI regarding the funding of types of
research - either to increase funding in a specific area, or
to reduce it. Reducing is just as important as increasing
because the research budgets are fixed every year and NCI can
only increase funding in one area by cutting it in another.
I don't know the exact numbers, but I'm pretty sure that upwards
of 100 people are involved in this process.
So there really is a lot of collation going on.
