Beautiful Bio-Luminescent Luciferase

Way back in 1974, I was already a nerd. I had a summer internship at the National Bureau of Standards (now called the National Institute for Standards and Technology or NIST). My posting was to the micro-calorimetry lab, where I got to work on a project to determine the heat of reaction of the luciferase based chemical reaction that happens in the tail of a firefly

At one point, we actually put a live firefly- (this is not the kind we used) in the calorimeter, and watched the heat being given off by the insect. It was a very sensitive instrument, and the energy graph was pretty ragged. But then there was a big spike. The whole unit was opaque, so we couldn’t see anything, but we figured that the firefly was lighting up at that point. Who knows, maybe it was just mad at us and trying to get out. We released it, unharmed. Not so lucky were the ones that got killed for their tails. I wondered if they paid little kids to go collect them.

I was informed of the chemical reaction that allowed the fireflies their trick. That had already been figured out years ago!

It was a fun summer. I realized then that I did not have the patience to work as a scientist, and decided to go to engineering school instead. Twenty years later, I ran across an article in a technical journal about how scientists had finally managed to do something practical by using this compound to make a field kit to measure oxygen levels in streams and other bodies of water.

What I had realized years before was that the scientists were just having fun.

Nothing wrong with that. So did I. And I am still working in the field.

They didn’t pay us much. If we didn’t have family need, we got I think $12.00 a week. It almost paid my part of the gas money I gave to the janitor and the technician who gave me a ride out to Gaithersburg. The janitor was a down to earth, friendly guy. The technician was more of a grouch. I wonder what they thought of me. There were not too many females in technical fields then. Even less than today.

  1. Liked this as an engineer’s memoir, a glimpse of the intellectual curiosity that is such a driving force in your life!
    That’s what I would love to see in my grandchildren’s faces as they explore the world we live in!
