Pipefish World!

One of the projects I’ve been working on recently is getting a citizen-science project involving Syngnathid fishes up and running. What is citizen-science, you ask? It is a way in which scientists collect data using volunteers outside of the science community. These volunteers can be anyone who is interested in science–children, families, fishermen, school teachers and classes, ANYONE!

My project is called “Pipefish World” and has a very basic premise: provide information and updates about seahorses and pipefish research to anyone interested in it, and to have people visiting the coast look for Syngnathids and send me their photographs. We have limited information about the distribution of these fish, and simply collecting photographs from people (preferably along with location information) can provide an incredible amount of useful data for us!

Here is the website, embedded in my lab website: http://www.bio.tamu.edu/USERS/ajones/Pipefish/Pipefish.html

Right now, we’re targeting the Gulf of Mexico (because that’s where we work so have access to), but if you see Syngnathids anywhere in the world I would love to hear from you! Please share this project with your friends & family, and if you see any pipefish or seahorses–take a picture and send it to me!

Practical computing for biologists: book review


Most scientists these days are coming to realize how imperative it is for them to be able to use computers. By this I don’t mean just being able to turn one on, use the internet and basic programs like Microsoft Word and Excel. No, I’m talking about using the command line and writing simple programs in languages like C++, Python, and Perl. These skills are not only desirable because they make you a more marketable job candidate–for many of us, they’re absolutely necessary to just access, manipulate, and analyze our data.

This is because new tecnologies, such as next generation sequencing options like the Illumina HiSeq macine, are generating huge amounts of data. Sequencing DNA in one lane on that machine will generate millions of sequencing reads, each of which contains ~100 base pairs of DNA. Although these are relatively short reads (genes, especially in eukaryotes, are hundreds or thousands off base pairs in length), the sheer number of them can become overwhelming when you start thinking about data analysis. The types of files that contain these data would be simply unreasonable to deal with in programs like Excel or Word.

Thus, biologists like myself are being thrust into the world of computer science. It can be frightening to get started, and can take a long time to really get comfortable using computer programming approaches. I have been writing a model simulating a population under different types of selection in C++ for over a year, and it still seems like every time I sit down to write a new block of code I end up learning something new!

But a couple weeks ago I sent my first batch of samples off for that in depth next generation sequencing that I mentioned before, and I realized that my piecemeal knowledge of C++ wasn’t going to cut it when I got my data back–I needed to become familiar with the command line and linux. So I picked up a wonderful book by Drs Haddock and Dunn called Practical Computing For Biologists. I’m about halfway through the book, and I already feel infinitely more confident with the command line, the unix shell, and python.

The book is written in an incredibly straightforward manner. Many computer programming books are full of jargon and can be very confusing; Practical Computing for Biologists is not one. It doesn’t go into unnecessary detail about how to do esoteric programming tasks. Instead, the book uses biologically relevant tasks, like searching a file full of data from various sampling sites for every data point from a particular place or date. The book has an accompanying website where a bunch of example files are available to be downloaded. The first few chapters instruct you on how to set up your computer and how to do basic tasks using the command line and text editors. Then it goes into using Python and writing programs, and then goes into more complicated programming tasks. I highly recommend this book for anyone who wants or needs to learn basic computer programming skills. It is a wonderful starting point, and soon your desk may begin to look like mine!


Happy Mothers’ Day! Plus, Mothers in Science

Mothers Day orchid

Today is the day in the US when everyone celebrates their mothers by giving them gifts, food, flowers, etc. It’s a nice reminder of how difficult of a job being a mom is.

Being a mom can be especially difficult in science, at least in academia. To become a tenured professor, usually one must spend long hours in the lab, not to mention the long hours outside of the lab writing up all the results. This can make it difficult to be a ‘normal’ mom, and some people point to motherhood as one of the reasons for the huge gender gap in science. The gender gap in science is actually still sort of a mystery–there tend to be more women than men entering science at the graduate school level, but there are still far fewer tenured female faculty members. Nature even had a special on the gender gap back in March:



But part of that special included stories about successful scientists who are also mothers, and how they’ve dealt with the demands of both jobs. There are myriads of articles out there that say the desire to have a family is the critical factor that holds women back from being equal to men in science, but I don’t really buy it. There are too many examples of successful female scientists who also have families for that to be a good argument, in my mind. But it is likely a factor. There are many challenges facing scientists, and it would seem that women have one extra. So I’m giving scientist mothers an extra shout-out today–keep working hard and inspiring the generations to come!

Also, Happy Mothers’ Day, Mom!
