What the future of science will look like if we’re bold enough to look beyond centuries-old models.
Over the last six months, I’ve had a number of conversations about lab practice. In one, Tim Gardner of Riffyn told me about a gene transformation experiment he did in grad school. As he was new to the lab, he asked two more experienced scientists for their protocol: one said it must be done exactly at 42 C for 45 seconds, the other said exactly 37 C for 90 seconds. When he ran the experiment, Tim discovered that the temperature actually didn’t matter much. A broad range of temperatures and times would work.
In an unrelated conversation, DJ Kleinbaum of Emerald Cloud Lab told me about students who would only use their “lucky machine” in their work. Why, given a choice of lab equipment, did one of two apparently identical machines give “good” results for a some experiment, while the other one didn’t? Nobody knew. Perhaps it is the tubing that connects the machine to the rest of the experiment; perhaps it is some valve somewhere; perhaps it is some quirk of the machine’s calibration.
The more people I talked to, the more stories I heard: labs where the experimental protocols weren’t written down, but were handed down from mentor to student. Labs where there was a shared common knowledge of how to do things, but where that shared culture never made it outside, not even to the lab down the hall. There’s no need to write it down or publish stuff that’s “obvious” or that “everyone knows.” As someone who is more familiar with literature than with biology labs, this behavior was immediately recognizable: we’re in the land of mythology, not science. Each lab has its own ritualized behavior that “works.” Whether it’s protocols, lucky machines, or common knowledge that’s picked up by every student in the lab (but which might not be the same from lab to lab), the process of doing science is an odd mixture of rigor and folklore. Everybody knows that you use 42 C for 45 seconds, but nobody really knows why. It’s just what you do.
Despite all of this, we’ve gotten fairly good at doing science. But to get even better, we have to go beyond mythology and folklore. And getting beyond folklore requires change: changes in how we record data, changes in how we describe experiments, and perhaps most importantly, changes in how we publish results. Read more…
BioCoder 6: iGEM's first Giant Jamboree, an update from the #ScienceHack Hack-a-thon, the Open qPCR project, and more.
Once again, we’re interested in your ideas and in new content, so if you have an article or a proposal for an article, send it in to BioCoder@oreilly.com. We’re very interested in what you’re doing. There are many, many fascinating projects that aren’t getting media attention. We’d like to shine some light on those. If you’re running one of them — or if you know of one, and would like to hear more about it — let us know. We’d also like to hear more about exciting start-ups. Who do you know that’s doing something amazing? And if it’s you, don’t be shy: tell us.
Above all, don’t hesitate to spread the word. BioCoder was meant to be shared. Our goal with BioCoder is to be the nervous system for a large and diverse but poorly connected community. We’re making progress, but we need you to help make the connections.
