Out of the Attic, Into the Lab: a talk about prototyping

OutOfTheAttic

On August 1st, I presented a talk entitled “Out of the Attic, Into the Lab: building a shrink ray is harder than it looks”. The talk was part of the Science and a Movie program, a series put on by Central Cinema and the Pacific Science Center. The series pairs talks from scientists in the Seattle area with silly or classic movies (in this case “Honey I Shrunk the Kids”).

In “Honey I Shrunk the Kids” Wayne Szalinski builds a prototype for a shrink ray in his attic. For many reasons, this is not the best idea (never leave your labs unlocked and unattended). But America has a long history of people inventing in their homes (think of Hewlett-Packard, or the telephone), so there’s got to be some appeal, right? In reality, the feasibility of working in a non-lab setting largely comes down to what the prototype is meant to do. A lot of new technology (computers, electronic testing equipment) is easy to make anywhere you have access to an empty space and electricity. But a lot of scientific technology (like the Large Hadron Collider, or, let’s be real, a shrink ray) requires specialized settings, materials, or people, and so is much easier to accomplish in academic settings.

This is especially true in my area of research, bioanalytical chemistry. Because bioanalytical chemistry focuses on identifying and quantifying chemicals that affect living things, we’re often using samples and methods that require a specialized physical space where we have a lot of control. For example, my graduate work has focused on understanding how the shape of a protein determines what job it does inside your body. Problem is, proteins are so small we have to develop special tools just to look at them. These tools can involve freezing the proteins, shoots lasers at them, putting them in extreme low-pressure environment,* etc. None of these things are particularly feasible to do in a garage. Plus, building bioanalytical machines in academic institutions gives me access to people who can help me work around design challenges or offer advice when things go wrong (and they always go wrong). Best of all, I don’t have to worry about accidentally shrinking any nosy kids.

Thanks to Central Cinema and the Pacific Science Center’s Meet a Scientist program for the opportunity!

* I don’t mean making them feel relaxed- we put them in an aluminum box, suck almost all the air out, and then move the proteins around.

Fair Judging

At the end of February, I returned to my hometown to judge my former high school’s science fair. You may remember the science fairs of your youth as a series of baking soda volcanoes and talked-to plants. But as with most other aspects of high-school-life, the looming threat of college applications has largely done away with those carefree cultural signifiers of childhood scientific studies. No, these kids, who go to a private college prep school and were competing for a chance to go to the state science and engineering fair, were often using science techniques I didn’t encounter until midway through college. Here are a few of highlights:

  • Studying a protein human saliva to track our internal clock.
  • Making wire meshes to  help improve flexible, wearable technology.
  • Creating a new model to predict the path of hurricanes in almost real time.
  • Using plants to remove and recover heavy metals from contaminated water ways.

Despite the above-average complexity of these projects, everyone was still in high school, and so much of my job as a judge was to help them practice and improve their science communication skills. As a judge, the task is relatively straightforward: go to your assigned category, stop by a poster, read it, and then ask questions of the student scientists. Repeat for each poster. Then, go to a different location and discuss with other judges the scientific creativity, research execution, and overall presentation quality. Pick one or two winners from your category to go on to the state or to be considered for the international fair, and you’re done.

I loved my experience as a science fair judge. I got to dust off some old skills (it’s been a while since I’ve thought about cell cultures or the DNA-replicating polymerase chain reaction), talk about some fiendishly clever science, and remind myself how exciting science can be when you’re just starting out.  And if you took more than the introductory course in any science in college, you too can be a science fair judge.

Also, in full disclosure, my favorite part might actually have been seeing friends and former teachers, who had also come back to lend their scientific expertise to the fair.
