Sydney Brenner, a ‘failed’ biologist from UK, delivered a thought-provoking talk in 2006.
The title of his talk was The Next 100 Years of Biology, but Brenner, whose scientific triumphs include establishing the existence of messenger RNA, shied away from speculation. Instead, he asked, What should we do over the next 100 years?
I think a lot of (biology) is going in absolutely the wrong direction, he said.
The Human Genome Project, for example, has led to what Brenner called factory science heavy investment in expensive gene sequencers that begin to drive the direction of research.
You have 100 machines; you’re looking at about $100 million of investment, he said. And you’ve just got to keep that going all the time in order to get the use from them.
This, he said, and the Genburo, the Politburo of Genetics, in which everything is decided stultifies research, and discourages young people from entering the field.
They think, ‘How can I work in a field where this guy has a lab of 300 people and all the tools and lots of money?’ And I tell you something; one good idea is worth more than all of that.
Because what we’re looking for is innovation, something new, Brenner said. And you won’t get something new if you work within a completely established mode of work. We need some people to stray off of the standard path and ask new questions.
Speaking in the crackling cadence of his native South Africa, Brenner took delight in piercing the latest biological trends, including the proliferation of omic sciences.
I was asked by a business journal in England, The Economist, which was the most important omic science for biotechnology, and I gave them the obvious answer: it was that science called econ-omics, he chuckled.
So we now have a culture which is based on everything must be high-throughput, Brenner continued. I like to call it low-input, high-throughput, no-output biology.
I’m not taking advantage of my advanced years in order to make cracks about this. But this is not the way to solve problems, he said.
The discovery of a gene, for example, doesn’t necessarily mean that the protein it encodes has an important function. You’ve got to have a theory on how the cell works, Brenner said.
The same goes for translational research.
The promise of the human genome is that we will have millions of targets and we can take all the chemicals, and we can just do high-throughput analysis on all of these and find all the drugs for everything for the future from bench to bedside.
I think this is totally wrong.
For one thing, this approach requires a therapeutic hypothesis, that blocking a particular target could affect a physiological function or prevent a disease.
It is very rare that I have seen coming out of basic labs hypotheses of these kinds, Brenner argued, mostly because most people in basic labs don’t know anything about human physiology and pathology.
So I believe that the process should be the other way around. I think what we can do very well now is to go from bedside to bench.
Ewan Birney, the most successful biologist from UK, used a figure to explain what Brenner should have been doing instead.
