Dispatch from a Baylor Summer Fellow | Enzo Henry

Most of my summer has been spent counting cells and trying to figure out why something hadn't worked. That's the whole of it, more or less. There's no result to report yet. The analysis is still in progress, and it will be for a while.

I want to be straight about that, because the version of research that shows up in a
blog post usually skips this stretch. It goes from a question to a finding. What actually fills the days is working through sections, keeping counts consistent, and going back through a failed run to figure out which step needs to change.

What I didn't expect is how much of a study's reliability lives right there. A figure in a paper looks like something that was simply found. In practice it's the sum of small decisions made by whoever was gathering the data, on days when nobody was watching and nobody would have known if the criteria drifted. Holding that line at hour three staring at my computer screen, debating on if a certain cell meets the criteria we are looking for isn't a technical skill. Sometimes the staining is unclear or nonspecific, and a cell sits somewhere between counting and not counting. The criteria don't settle that for you. You settle it, and then you have to settle it the same way for every ambiguous cell after it, including the ones you get to when you're tired and want to be finished. Nothing outside of you enforces that.

I'm hesitant to claim more than that. Counting cells taken from mouse tissue is a long way from a worldwide breakthrough, and I didn't do the part of this project that reaches a person. What it showed me is that the trustworthiness of scientific work gets built quietly, upstream, by people who did the tedious portion correctly. If service means anything in a lab, I think it looks like that.
