Mauro Copelli, Leonardo Lyra Gollo e eu estamos submetendo um paper sobre dendritos ativos no PlOS Computational Biology. Parece ser uma revista interessante. Alguns extratos de uma reflexão publicada em 2005.

“Antedisciplinary” Science

“The scale and complexity of today's biomedical research problems demand that scientists move beyond the confines of their individual disciplines and explore new organizational models for team science. Advances in molecular imaging, for example, require collaborations among diverse groups—radiologists, cell biologists, physicists, and computer programmers.” —National Institutes of Health Roadmap Initiative [1]

Reading this made me a little depressed. For starters, the phrase “organizational models for team science” makes me imagine a factory floor of scientists toiling away on their next 100-author paper under the watchful gaze of their National Institutes of Health program officers, like some scene from Terry Gilliam's movie Brazil.
It's also depressing to read that the National Institutes of Health thinks that science has become too hard for individual humans to cope with, and that it will take the hive mind of an interdisciplinary “research team of the future” to make progress. But what's most depressing comes from purely selfish reasons: if groundbreaking science really requires assembling teams of people with proper credentials from different disciplines, then I have made some very bad career moves.

I've been a computational biologist for about 15 years now. We're still not quite sure what “computational biology” means, but we seem to agree that it's an interdisciplinary field, requiring skills in computer science, molecular biology, statistics, mathematics, and more. I'm not qualified in any of these fields. I'm certainly not a card-carrying software developer, computer scientist, or mathematician, though I spend most of my time writing software, developing algorithms, and deriving equations. I do have formal training in molecular biology, but that was 15 years ago, and I'm sure my union card has expired.


Progress is driven by new scientific questions, which demand new ways of thinking. You want to go where a question takes you, not where your training left you. We may not have a single clarion call to arms like Schrödinger's What is Life? driving physicists into biology right now, as in the beginnings of molecular biology. But we do have powerful new technologies to harness (computational biology), newly revitalized approaches to old problems (systems biology), and new areas altogether (synthetic biology).
New disciplines eventually self-organize around new problems and approaches, creating a new shared culture. This shared culture coalesces into the next essential training regimen for the next generation of scientists, and with luck, some of these people will overcome their training to open up more new fields of inquiry. Interdisciplinary science is just the embryonic stage of a new discipline. To value interdisciplinary science for its own sake is to value history over progress—that is, to value people's past training more than their current work.

I wonder if it's the success of the Human Genome Project that led us to this. The scale of the genome project required “big science” and large teams. The genome project also fueled the explosive growth of the highly successful field of computational biology. Did the ideas of interdisciplinary science and large teams become inappropriately intertwined? Certainly, achieving the goals of the Human Genome Project required engineers, physicists, and computer scientists.
It would be silly to argue against large interdisciplinary teams where a mammoth technical goal can be clearly defined. But when I think of new fields in science that have been opened, I don't think of interdisciplinary teams combining existing skills to solve a defined problem—I think of single interdisciplinary people inventing new ways to look at the world.
Focusing on interdisciplinary teams instead of interdisciplinary people reinforces standard disciplinary boundaries rather than breaking them down. An interdisciplinary team is a committee in which members identify themselves as an expert in something else besides the actual scientific problem at hand, and abdicate responsibility for the majority of the work because it's not their field. Expecting a team of disciplinary scientists to develop a new field is like sending a team of monolingual diplomats to the United Nations.


To encourage the rise of new disciplines as successful as molecular biology, we need to encourage individuals to leave old disciplines behind and forge new fields. New science needs to be judged on its merits, not by the disciplinary credentials of the people doing it—particularly in fast-moving interdisciplinary areas where any formal training may be outdated anyway.
If your grant proposal includes statistical analysis, your reviewers shouldn't be acting as enforcers requiring you to have a card-carrying statistician as a collaborator. Maybe in your narrow area, you know how to do the relevant statistics as well as any formally trained statistician.
A proposal invoking high-performance computing should not get held up until you enlist collaborating computer scientists, who may not even be interested in your problem. Maybe you know how to use a supercomputer well enough to do what you propose.


Perhaps the whole idea of interdisciplinary science is the wrong way to look at what we want to encourage. What we really mean is “antedisciplinary” science—the science that precedes the organization of new disciplines, the Wild West frontier stage that comes before the law arrives. It's apropos that antedisciplinary sounds like “anti-disciplinary.” People who gravitate to the unexplored frontiers tend to be self-selected as people who don't like disciplines—or discipline, for that matter
Computer science mythologizes the big teams and great computing engines of Bletchley Park cracking the Enigma code as much as we mythologize the Human Genome Project, but computer science rests more on the lasting visions of unique intellectual adventurers like Alan Turing and John von Neumann.
Looking around my desk at the work I'm trying to build on, I do see the human genome paper, but even more, I see the work of individual pioneers who left old disciplines and defined new ones—writing with the coherence, clarity, and glorious idiosyncrasy that can only come from a single mind.

Eu acho que já disse isso antes, mas Leonardo da Vinci deve estar dando murros na tampa do caixão!... E Gamov doido para reencarnar!... :D

Caro Osame

Acho que muitos anos atras tivemos uma discussao sobre temas tocados neste artigo.
Como avança a ciencia? Devido a esforços coordenados de várias mentes (grupos)? ou a avanços de pesquisadores independentes? Aqui não oponho N contra 1, mas muitos contra poucos (n~<4 )

Acho se o Alzheimer nao impedir, que lembro que voce defendia N. Eu defendia a posição n


Osame Kinouchi disse...

Hum, eu acho que defendia n > 1 e vc n=1, mas tudo bem, dou o braço a torcer...
