Ten percent scientist: Developing your science communication skill set

What does it take to be a scientist in addition to collecting and analyzing data?

Since most people aren’t looking in on your lab mice or peering at the graphs on your computer screen, they rely on you to shape the meaning of your work. In the competitive world of academia, where the ‘impact’ of publications is becoming just as important as the quantity of publications, communication skills are becoming a key part of a scientist’s job.

Scientists have traditionally been reluctant to engage with the media and the public. Yet if scientists step back and leave communication in the hands of the media, their work is too often reduced to ‘morning show gossip’. (See John Oliver’s entertaining clip on science hype here.) It’s incumbent on the scientists themselves to communicate about their work responsibly and lead others do the same.

Because of the general excitement over microbiome science and its potential to impact so many aspects of how humans live, results from this field are particularly prone to distortion in the media. Here are some examples of how science communication can go awry (keeping in mind that I’m not trying to pick on any particular news outlet):

Obesity could be contagious, scientists say (based on this study)

Gut bacteria affecting both our cravings and moods to get us to eat what they want: University of New Mexico Study (based on this review/opinion)

Exercise is good for your gut bacteria, too (based on this study)

In the next Human Microbiome Journal Club, I’ll be visiting to lead a discussion on why the next generation of scientists will need to become ten percent scientist, ninety percent communicator. It’s not that you need to spend ninety percent of your time communicating — but that you’ll benefit throughout your career if you constantly think about the role of your work in the wider world.

From my perspective as a science writer, I’ll give you some tips on how to get others interested in your research without resorting to cheap tricks. We’ll cover the different audiences who need to know about your work and how to target each one. I’ll give you some examples of microbiome scientists who are great communicators,  and we’ll talk about a few guidelines on how to start engaging with a minimal commitment of time.

Join us in MUMC 3N10A on Friday, June 3rd, at 3:00 pm. We’ll continue the discussion over drinks afterward!

Science writer Kristina Campbell, from Victoria, BC, is a freelancer whose work has appeared in publications throughout North America and Europe. She consults on microbiome-related medical education projects and works as a web editor for the Gut Microbiota for Health website. Kristina is also co-author of an upcoming cookbook and an Elsevier textbook on nutrition & gut microbiota.

A network based approach to longitudinal analysis of the microbiota

tileshopAnalysis of the microbiome over time is hard. You can treat the abundance of each bacterial taxa as a separate outcome and look at them all individually but then you lose interactions between them. Worse yet, you can treat each measurement time point as separate, to get a picture of the interactions, but lose the connections between time points.

This week in journal club we will explore an alternative to longitudinal gut microbiome modeling – Network-based methods. After a simple introduction to longitudinal modeling and the different types of network methods we will look at a new implementation of one network method for longitudinal microbiome analysis from McGeachie et al. 2016 called Dynamic Bayesian Networks. In this paper they present the method and try it out on real data (16S rRNA gene profiles) from infants sampled every day in a neonatal intensive care unit. It’s important that you attempt the paper and google some of the terms before attending but I’ll do my best to explain the concepts used so that we can have a lively discussion.

Journal club will be this Friday April 29th from 3 – 4 pm in MUMC 3N10A. Afterward we will retire to the pub for a pint and to talk about a new view of the tree of life or maybe What Is the Tree of Life?

April journal club: genomes from metagenomes.

Research into the composition and effect that the human microbiome can have on its host has advanced significantly with the application of 16S rRNA gene sequencing techniques and improvements in next generation sequencing technology. Using this marker gene, we can get a pretty good picture of “who” is there using standard, easy-to-use techniques.

However, in order to move forward with mechanistic, functional research, we need to know more than the coarse outline of the bacteria that are present in these communities. First, 16S studies only allow for the identification of the bacterial portion of the microbiome (though we have looked at ways of assessing fungal communities as well in past JCs). Additionally, 16S sequencing does not have the ability to differentiate between bacterial strains, and at the length that most high-throughput methods are currently optimized for, sequencing of specific regions of the 16S rRNA gene generally can only identify bacteria accurately to the genus level.

Inevitable advances in the biology and sequencing will improve 16S sequencing in the coming years; however, another interesting avenue for studying the composition of the (human) microbiome is by whole genome shotgun metagenomics. This method is advantageous in that they give us more biological information about a sample by identifying the genes that are present, and non-bacterial components such as viruses, phage, and fungi. However, if we do not have the computational tools to be able to re-assemble the metagenomic jigsaw puzzle into individual genomes, mechanistic and functional research will still be difficult.

This Friday, we will be examining a semi-recent paper entitled “Identification and assembly of genomes and genetic elements in complex metagenomic samples without using reference genomes” where Nielsen et al. design a bioinformatic approach for sub-dividing the jigsaw puzzle of metagenomics into neat little piles, each representing a genome present within the sample.

Together we’ll investigate:

-the what of this algorithm (for a non-bioinformatic audience): what it is, and how it works to disentangle the input information into pseudo-genomes

-the howhow the authors applied this algorithm to a set of gut microbiome samples from which they identified and assembled 238 microbial genomes

For those who stick around to philosophize over beer, we can discuss the future of metagenomic technologies, how it might interact with 16S sequencing for the microbiome centre-stage, and how algorithms like these could be used to explore the human microbiome further.

Details: I will give a short presentation with discussion Friday, April 1st (no joke) at 3:00pm in HSC-3N10A (just outside of the Farncombe Institute). Following, all are welcome to continue discussions at the Phoenix.

Note: You MUST read the paper! This is a more technical paper than we usually pick, but you must make an honest effort to go through the manuscript to attend HMBJC. Highlight areas you are unsure of, and we’ll go through them together!

Working Group: updated room information

Hello fellow microbiome-explorers!

Our drop in, bring-your-data&questions style, working group format is still kicking every Tuesday from 3:30pm on. Our room booking moves around a bit, so I would just like to update you that we will be in MUMC 2v7 from now until May 3rd 2016, when we move to MUMC 4N55A.

See you next week!

Citizen Science and the Microbiome: uBiome studies women’s health

Everyone that reads this blog has some stake in the human microbiome game, so I’m assuming that you would all be interested in exploring your own personal microbiomes!

If you haven’t heard of them by now, uBiome is a company started via a crowdsourcing effort in the San Francisco Bay Area back in 2012 with personal microbiomes in mind. They now provide sampling kits (internationally!) for you to test your own microbes at any of the five physical sites they currently study: skin, nasal, oral, gut, and genitals.  In addition to each sampling kit is a health survey.  The information uBiome gets in each of these surveys allows the data from the resulting microbiomes to be included in larger research projects (with your permission of course), both at uBiome and with various collaborators.

The latest project being pursued by uBiome is a women’s health initiative (sorry guys, this one’s for the ladies!).  The new study will make use of citizen science and the uBiome platform to delve into the changes in the vaginal microbiome throughout both the menstrual cycle and different phases of life.  Anyone that meets the criteria and wants to participate, anywhere in the world, can opt into the study.  Participating means that you not only get to learn about your own microbiome and how it stacks up against other women around the world, but you also get to be a part of a larger initiative towards advancing women’s health.  As an added incentive, uBiome provided the first 500 kits for free (all of which were claimed in under two days), and any kits beyond those initial 500 are being provided at a discounted price.

Between social media and word of mouth, innovative ventures like uBiome may be the most relevant new way to study broad topics like the microbiome.  Citizen science initiatives brings a whole new brand of participation in research studies to the field.  I for one can’t wait to see what they’ll do next.

Does dysbiosis drive intestinal inflammation or is dysbiosis resulted from inflammation in IBD?

This Friday the 13th at 3:30pm we continue journal club to discuss: Lewis et al, 2015. Inflammation, Antibiotics, and Diet as Environmental Stressors of the Gut Microbiome in Pediatric Crohn’s Disease.

Dysbiosis, a term that is often misused and over simplified as a reduction in diversity and altered bacterial composition, will be the highlight of our discussion this week. It is well documented that patients with Inflammatory Bowel Disease (IBD) have an altered microbial composition however, is this altered composition a result of inflammation or does it drive inflammation? This paper claims that dysbiosis is reduced when inflammation is reduced. Moreover, inflammation, antibiotic exposure, and diet independently influence specific taxa meaning the response of the gut microbiome depends on the environmental stressor.

Please join us for a great discussion at West End Pub @ 3:30pm!
