Last Friday, five of our salon contributors gave public talks at the SoundBio lab, a nonprofit DIY biology lab in Seattle. These talks were the result of the Talk Stream from this Spring’s Salon SciComm workshop series. Our group worked together to draft and practice a series of presentations for a general audience. Each talk was 5-10 minutes with minimal slides, and were based on topics we each thought would be novel and exciting to science-interested people.
Bryce Taylor, Postdoctoral Fellow
My talk focused on ways model organism research can tell us about ourselves. I focused on how efforts to understand the function of genes in yeast and other model organisms gave us a head start in interpreting the human genome. I then honed in on an example where different versions of human genes were engineered into yeast. This allowed scientists to determine whether certain individuals carried versions with a reduced function that could predispose them to diseases like cancer.

My talk (entitled Driven by Data: A scientist reads the news) was about how anyone can use scientific reasoning to evaluate claims about science made in the popular media. I started by describing the 2011 neutrino speed controversy, in which physicists who observed neutrinos moving faster than the speed of light enlisted the help of the scientific community, including their competitors, to evaluate the accuracy of their findings. In the end, the physics-defying measurement was due to a small error which was found in the collaborative investigation. The reasoning process that the scientists went through when deciding whether to accept the neutrino measurement can be applied by anyone, to any scientific claim (and can be adapted to evaluate lots of other kinds of claims).
1) Is the claim consistent with our expectations? If not, why?
2) What did the study do? Are there any problems with this?
3) Does the study support the claim? If so, are we ready to change our expectations?
With audience participation, we examined a health claim popularized by the New York Times: the “Scientific 7 Minute Workout”
. By examining the article text and a few additional publicly accessible resources we were able to conclude that while the study referenced by the New York Times might have been sound, the claims made by the paper were not supported by the study or by other information provided. We ended by discussing the responsibilities of scientists, journalists, and readers in ensuring that information is conveyed accurately.
Sarah Nelson, Research Scientist
My talk took a critical look at the growing world of the “quantified self:” the way people are increasingly accessing and using personal data to influence their thoughts and actions. I began with an introspective personal anecdote about how I’ve started tracking my daily bike commutes with a smartphone app. Despite years of intrinsically enjoying this part of my routine, I am now drawn to checking my “stats.” I then introduced consumer genomic testing as another type of quantified self activity. I described how customers can access reams of “raw” or uninterpreted genetic data through these tests, which can then be taken to various third-party interpretation tools online. I showed why these interpretations should be taken with a huge grain of salt, despite how fun and interesting they may be. Quantified self technologies will likely continue to grow in the future, so I encouraged the audience to take note of when and why they are engaging in such practices and to ask what other knowledge they might be leaving out.
Seungsoo Kim, PhD Candidate
My talk explained what a genome is, how it works, and why we should care. We can understand the genome at multiple levels, from being the basis of heredity and why you look like your parents, to being present in each of your many different cells and telling those cells how to do their many different “jobs,” and even to how the physical genome is packaged in three-dimensional space. I used the analogy of a cookbook, where you get some recipes from your mother and others from your father. The recipes in a cookbook represent genes, which are not used by all cells – each cell type has a favorite subset, which it “bookmarks” using epigenetic modifications. Finally, I described a few ways in which the genome’s functions can go wrong in disease, which is one reason we should continue to research how the genome works.
Elizabeth Morton, Postdoctoral Fellow
My talk was on the development and use of green fluorescent protein (GFP) as an imaging technology. I described how this protein was isolated from a jellyfish native to the Pacific Northwest and explained how GFP finally allowed us to track molecules in living cells, an advancement that eventually led to a Nobel Prize. I explained a little about the scientists that were involved in the discovery of GFP and their various contributions. I wrapped up with showing the array of different colors of fluorescent proteins available now, with some brief examples of particularly medically-relevant applications of GFP today.
