It’s not uncommon to hear stories of mistakes resulting in graduates students missing paychecks. This is a major problem because most students live month-to-month and can’t wait for a missed check to be fixed in the next pay cycle. Despite the commonness and dramatic impact of missed pay in graduate school*, it’s common to see these issues written off as isolated incidents and not part of a more systematic problem.

The weecology group is coming in force to the annual meeting of the Ecological Society of America which is being held in New Orleans next week. We’ve been up to a quite diversified list of things over the past year ranging from temporal dynamics of communities to forecasting and remote sensing. We also have people involved in a number of outreach or training events this year.

We have a new paper out. It’s not exactly news, because the paper has been up on bioRxiv since December 2016 and hasn’t changed too much. All of the work was done by Nick Clarke when he was a PhD student in the lab. This post is to explain our new paper to a general audience.

This post has been in my drafts folder for a while. With the World Cup here, it’s time to post it! It’s a rule that a 3D assembly of hexagons must have at least twelve pentagons in order to be a closed polyhedral shape. This post takes a look at why this is true. First, some examples from nature. The stinkhorn fungus Clathrus ruber , has a largely hexagonal layout, with pentagons inserted.

I’ve written in the past about instrumentalism, the scientific practice of treating theories as tools that can be evaluated by their usefulness, rather than as claims that can be evaluated as true or false. If you haven’t tried this way of looking at science, I highly recommend it! But if theories are tools, what are they used for? What makes a theory more or less useful?

A while back, the lab moved to an electronic lab notebook (details here and here). One of the drivers for this move was the huge number of hard copy lab note books that had accumulated in the lab over >10 years. Switching to an ELN solved this problem for the future, but didn’t make the old lab note books disappear. So the next step was to archive them and free up some space.

This wonderful movie has repeatedly popped up into my twitter feed. http://quantixed.org/wp-content/uploads/2018/04/ctenophore.mp4 It was taken by Tessa Montague and is available here (tweet is here). The movie is striking because of the way that cytokinesis starts at one side and moves to the other. Most model systems for cell division have symmetrical division. Rob de Bruin commented that “it makes total sense to segregate this way”.

I read about Antonio Sánchez Chinchón’s clever approach to use the Travelling Salesperson algorithm to generate some math-art in R. The follow up was even nicer in my opinion, Pencil Scribbles. The subject was Boris Karloff as the monster in Frankenstein. I was interested in running the code (available here and here), so I thought I’d run it on a famous scientist.

We are excited to announce the first release of a new Julia package that let’s you run our Data Retriever software with a native Julia interface. For those of you not familiar with Julia it is a new programming language that is similar to R and Python, has a central focus on data analysis, and is designed from the ground up to be fast. It is an emerging scientific programming and data analysis language.

You might be familiar with Arthur C. Clarke’s Third Law, “Any sufficiently advanced technology is indistinguishable from magic.” Clarke tucked this away in a footnote without explanation, but it fits in with the discussion of magic in Chapter III of James Frazer’s magnum opus The Golden Bough . These two works have shaped a lot of my thoughts about science, technology and the way we interact with our world.
