If I struggle to find the answer to something, it must be worth a post to help out others. So, here’s where to find the php.ini file on a standard WordPress install on Raspberry Pi. I installed a LAMP stack and WordPress on a Raspberry Pi following these excellent instructions. The aim was to import our lab’s ELN onto a fresh WordPress install.

The Retropie project is a wonderful way to play retro games on a Raspberry Pi (see previous post). A number of handheld units are available to make a convincing retro gaming experience. One of these is the Retroflag GPi case, modelled on Nintendo’s Game Boy. It’s possible to order one of these pre-built and even loaded with games, but where is the fun in that? Here is a quick guide to building one.

I have a long-running project Raspberry Pi project to make time-lapse movies of a countryside view (see previous posts). It’s been running for over two years and the results are great. The camera takes images every ten minutes and by assembling movies with different time intervals, you can see seasons change, trees growing or the sun setting and snow melting. The sky is mesmerising to watch.

The aim of this post is to look at revisions of bioRxiv preprints. I’m interested how long preprint versions exist on bioRxiv. In other words: how long do revisions to preprints take? The data from bioRxiv is a complex dataset with many caveats as I’ll explain further down, but some interesting details do emerge. Consider this a sketch of the dataset rather than an in-depth analysis. I’ll walk you through the code.

This post is an update of a previous analysis on quantixed. We have covered publication lag times – the time it takes for a paper go from submitted (received) to accepted and published – a lot on here. It is possible to look at lag times, in R using data from PubMed. Previously my code performed these calculations using an XML file downloaded from the PubMed website.

As the COVID-19 pandemic continues, different countries are experiencing various restrictions including lockdowns. Some of these restrictions alter our ability to do science: by hindering lab access or taking time away from researchers for homeschooling. So, what impact has the pandemic had on scientific output? One way to look at this – for biology – is to look at newly deposited papers on bioRxiv.

Clathrin is a three-legged protein complex or triskelion that can assemble into lattice-like structures. Inside the cell, this assembly helps to create vesicles: tiny packages of membranes containing proteins and goodies for the cell to use. Incredibly our first view of assembled clathrin was made in the 1960s, with resolution improving steadily since then. The image below shows these improvements.

The scientific response to the COVID-19 pandemic has been astounding. Aside from efforts to generate vaccines, the genomic surveillance of the virus has been truly remarkable. For example, the nextstrain project has sequence many SARS-CoV-2 genomes. In fact, the rapid identification of multiple new strains and mutations by diverse groups of scientists has resulted in a nomenclature crisis.

Reading about someone else’s recovery-after-injury story can be a bit dull. At least that was my conclusion after pressing delete on my story a moment ago. Having spared you the details, the summary is: I got injured. It hurt. It took me a year to recover because I didn’t tackle the recovery properly.

We have a new paper out! I am a bit late with this post, since the accepted version went online in December 2020, and the final version appeared a few weeks ago. It will shortly appear in a finished issue of the journal so I can tell myself that I am not too late yet. What’s it about? A complex of TACC3-chTOG-clathrin-GTSE1 is important for stabilising the mitotic spindle during cell division.

Many running races and events have been cancelled or disrupted due to the pandemic. To fill the void, I’ve been taking on Garmin’s “Challenges”. In Garmin Connect, you can accept a challenge set by Garmin (I think users can challenge each other too). Completion of these challenges gives the user points, which I’ve become somewhat obsessed with.
