Jack
: Youre a Harvard boy aren't you?
Andrew: I got my
Ph.D. at Berkeley. Post-doc at Harvard.
Jack:
And then you went to Iowa - for the sake of your children?
Andrew: For the sake
of my children. I've always been in a big city, and I went to Iowa. I
went to a small pond to try to begin a research program there that was
independent of the big fish at Harvard.
Jack:
And now you're off to Chicago
Andrew: Ive
begun there. University of Illinois, Chicago.
Jack:
Youre from an artistic background. You were going to be a concert
pianist
Andrew: Uh, huh.
Jack:
Your parents are artistic. Your presentation was extraordinary. I don't
know what the scientists made of it, but it was rather theatrical. And
it helps to show cool videos of chromosomes being yanked out of cells.
Andrew: Well, thank
you. [LAUGHTER] I've had a lot of good comments and feedback about my
presentation, you know, from the scientists here, which is very gratifying.
Thats better than money in the bank for us. That kind of acceptance
is an important component of ones productivity and of ones
desire to continue doing what ones does. If what you are doing is met
constantly with the reaction that youre doing the wrong thing or
were not interested, or that's not important
- which can be the case then its really tough.
Andrew: My publications
have. Our approach is pretty fundamental. On purpose. You take really
important contributors to science, you read about Max Delbrück, for
example, or Barbara McClintock or Jane Goodall; its good to read
what other people have written about these figures and their discoveries.
Its through them that one can learn what creative science is all
about. It may be necessary, if you have made a discovery, to set your
findings up against a fundamental premise, and to undermine it. That may
be the whole task. That's where the innovations come from. Theres
a procedure to doing revolutionary science or even science that pushes
back the boundaries a little bit.
Jack:
And you're a revolutionary scientist?
Andrew: I try to
do revolutionary science. I don't derive a lot of pleasure from dotting
I's and crossing T's. I've only rarely published on the same thing twice
for example. In terms of the nervous system, the first group I really
worked with was the first to map out the cytostatic pathway that causes
seizures - down to the synaptic level in the brain. That was done through
paying exquisite attention to the continuity of nerve fibers that course
from the brain via the nervous system and through the body. We could label
every one of those fibers, so our study essentially entailed the watching
of continuity in the way that system works. As a matter of fact that's
where animal cell tissue culture came from in the 1930's. They didn't
know if the nervous system was this continuous mesh until Harrison took
brains out of animals and put em in dishes and saw that there are
individual units called neurons.
Jack: Lets talk about the cell, and that may bring us to the question
of reductionism. I have had a lot of lessons here at this conference,
about the cell, the division of the cell, and the things that are travelling
around within the cell. It is tremendously busy inside there, inside that
lil cell.
Andrew: Yes. And I
use to love reading about it, going back to when people were first talking
about cells, which is where you have to start to understand the history
and the thinking about a subject. So for me it begins on the public library
bookshelf with one of E.B. Wilsons, The Cell in Development
and Inheritance, 1925
Its peculiar in a
way, but its very interesting the way he begins that book. The very first
sentence in the very first paragraph in the first chapter says that the
term cell is a misnomer. And you must remember that the cell
was though of as an empty room. Another image of the cell
that people had was of a water-filled balloon. Now those ideas
that we had about cells came from a different century of plant biologists
who were looking mostly at dead material.
I am thinking here of people
like Robert Hook. [Robert Hook (1635-1703), English Physicist who looked
at a thin slice of cork under powerful hand lens and discovered a large
number of cells.] Well, we now know that the cell is anything
but an empty room, or a water-filled balloon. The cell is filled. It is
packed. It contains fibers, vesicles, proteins, and different arrays of
structures; we are still trying to find them all, study them all, and
understand them.
The modern definition of
the cell has changed and, strictly speaking, they should do away with
the word altogether, and invent something else to call it, more on the
level of what it really does. I mean a single cell gives rise to a whale.
The potential of a cell is truly enormous. Imagine the biomass of the
earth, all of this planets organic material. It all came from one
cell, and then another and another; and each cell was not an empty room.
It was all built up from little, living entities, some which remain ill-defined,
the size of a few wavelengths of light. The study of cells and biological
systems is different from the other exact and physical sciences; thats
one of the reasons why, for example, researchers from the physical sciences
are now coming in droves to study biology.
Essentially we are learning
to see our work in a more comprehensive fashion as being connected to
the other sciences, to Nature in general, to the Universe and to Time
itself. It is to me a wonderful thought about Nature and Time that the
clam that we have here around us today tastes or may exactly the same
as the clams did around 800. We know that from the fossil record. As George
Gaylord Simpson and other evolutionists used to say, they probably -if
you cooked them the same way theyd taste the same. [LAUGHTER]
Whereas a mountain range like this would come and go 40 -50 times in that
same period. this [The interview took place in Banff, Canada, looking
out at the Rocky mountains] So there is something stable about these so-called
cells and the way they hook up to their external environment, which we
call the matrix. And the modern definition of the cell has become the
cell plus its unit matrix. This indicates outward connection, a connection
outside the cell
Jack:
Ive interviewed quite a few people here about cells and the like.
Different people have described the cell in different ways. Its
like a castle. Its like an American city and City Hall is in the
cells nucleus. That the genes were some kind of ah, minister of
finance. They inform the rest of the system you could have so much resources
here and so much there
Andrew: This is what
people have been saying -?
Jack:
Yes, And one scientist told me she thinks the cell is a complete control
freak. I asked her if she thought the cell is like a fascist state and
she said, Yes, yes, it sort of is. fascist state?
Andrew: Fascist state
Hmm!!!
[LAUGHTER]
Jack:
I'm sorry. [LAUGHTER] Youre not comfortable with that?
Andrew: Well, I had
a moment to think about it. Youre making an analogy obviously, because
we dont have such terms in biology. If you were to ask me is it
a democratic state Id have to take a moment. [LAUGHTER]. What does
come to mind is a new concept thats emerging in the biological sciences;
so we might be able to talk of a mutualist state. Its an extreme example
of mutualism between different entities co-operating. The prime example
is the mitochondria [energy-producing units that power all cells] and
the way theyve become co-operative. Whats more, co-called
eukaryotic cells are made up or organisms other than bacteria, but its
thought that they were once bacteria that is to say, free living
organisms which then got incorporated. All of your cells essentially have
these protobacteria in them that have come from a different
era. Even the genes in each cell have been shuttled around such that 80%
or so have been contained in the host cells nucleus. And these protobacteria
and these genes have acquired higher selective advantages. Down through
the ages, they have been become incorporated but also theyve exchanged
parts. Now theyre functioning like a watch. It is via this mutualism
that everything is driven. In much that takes place within the cell there
is this mutualistic interaction.
Jack:
Its collaborative
Andrew: Yeah. For
the most part. I study cancer cells where things arent collaborating
so well. You can have both sides of the story. The living state has beautiful
examples of co-operativity and mutualism. And its opposites as well.
Theyre co-existing in the same system, in the same place at the
same time.
Jack:
Right.
Andrew: Its
a very large thing. When you think of a cell its quite natural for
you to think of something microscopic often, but you have to extend your
thinking to -
Jack:
The yolk of an ostrich egg [Which, large as it is, is still regarded as
a cell]
Andrew: Well, no,
even bigger than that. You have to look at lichens, look at the oceans.
Theyre filled with blue or green algae.
