EEGor on Proteins: A Brain-based Perspective on Crowd-sourced Protein Structure Prediction

EEG-based Brain-Computer Interfaces (BCIs) are becoming increasingly popular, with products such as the Muse Headband and g-tec’s Unicorn Hybrid Black taking off, while in the protein folding space, Fold It and distributed/crowd computing efforts like Fold@home, don’t seem to be talked about as much as they once were.

Game-ification is still just as effective a tool to harness human ingenuity as it once was, so perhaps what is needed is a new approach to crowd-folding efforts that can tap into the full potential of the human mind to manipulate and visualise new 3D structures, by drawing inspiration directly from the minds of users…

How COVID-19 affected my (undergrad) masters

The COVID-19 pandemic hit us all in different ways, and this is a short look into how it affected me, a biochemistry undergrad doing my masters project in OPIG.

The first thing that impacted me was the move to working from home. Now you might think that as the group does only computational work that our work might not be too affected by working from home, as all the servers etc. can be accessed remotely. To a certain extent, this is true, it is possible to work from home for starters. Things may well be right as rain for a few people, but it wasn’t for me. I think a lot of people are finding that things take longer when not in the office even under the best circumstances. Technology and equipment can also reduce your productivity quite majorly. Not having a very fast computer (mine is 5 years old and you can tell) or poor chairs that give you backache (living that wooden dining room chair life) are just examples of things that affect your productivity, and also not something most of can do about.

10 reasons why LGBT Pride is still necessary

We are starting the LGBT Pride Month, which commemorates the Stonewall Riots (1959). It has rained a lot since that June 51 years ago when a group of transgender, gay, lesbian, and bisexual people rebelled against the police fighting for their rights, inexistent at that time. Fortunately, the situation has changed for the better: in 2011 the UN National Assembly approved the first Human rights, sexual orientation and gender identity resolution, and the difference between sex and gender is not and up to date, 29 different countries recognise same-sex marriage. Therefore, do we still need to celebrate/commemorate/revindicate LGBT Pride? Yes, yes and one thousand times yes. Why? Here I give you only 10 reasons, but it would not be difficult finding 100 more.

Visualising macromolecules and grids in Jupyter Notebooks with nglview

If you do most of your work in Jupyter notebooks, it can be convenient to have a quick visualisation tool to view the results of your latest computation from within the notebook, without having to flick between the notebook and your favourite molecule viewer.

I have recently started using NGLview, an IPython/Jupyter widget, to do this. It is based on the NGL viewer, an embeddable webapp for macromolecular visualisation. The nglvew module documentation can be found here, and in addition to handling the usual formats for molecular structure (.pdb, .mol2, .sdf, .pqr, etc.) and map density(.ccp4 and more), it supports visualising trajectories and even making movies.
