Genetics Unzipped: The accidental discovery of genetic fingerprinting

Posted by , on 26 March 2020

35 years ago this month, a small team of scientists at the University of Leicester published a paper in the journal Nature that changed the world. Written by Alec Jeffreys, Victoria Wilson and Swee Lay Thein, the title, ‘Hypervariable ‘minisatellite’ regions in human DNA’ and the jargon-filled results talking about dispersed tandem-repeats and allelic variations don’t provide much of a clue unless you know what you’re looking at. 

But it’s this last sentence of the abstract that’s the real giveaway: “A probe based on a tandem-repeat of the core sequence can detect many highly variable loci simultaneously and can provide an individual-specific DNA ‘fingerprint’ of general use in human genetic analysis.”

In the latest episode of Genetics Unzipped, we take a look at the story of genetic fingerprinting, and some of the very first ways in which this game-changing technique was put to work.

Labs in lockdown II

Posted by , on 25 March 2020

A couple of weeks ago we posted a collection of tweets from scientists about COVID-19. A lot has changed since that time – we in the UK are two days in to our own lock down, along with many parts of the world – and so we thought it would be a good time to share some more perspectives from the science Twittershere in the time of the pandemic. You’ll hopefully find some of it is useful, some thought-provoking, and some light-hearted. Feel free to share any other online nuggets in the comments.

 

Firstly, remember it’s a pandemic

Time to crack coding?

Posted by , on 24 March 2020

As labs shut down in response to the coronavirus pandemic, some might be unsure of what to do next. Even if your project doesn’t have a computational (i.e. bioinformatic) aspect, knowing some code can still be useful to present your research. Importantly, learning to code is particularly well-suited for the current situation, because there are a lot of free resources online that make it possible to learn by yourself with just a computer.

Before I go any further, I must acknowledge that during this time, many researchers will find themselves in a strange and stressful situation to which everyone will react differently. Although some will see this as an opportunity, others might feel they should be productive and find that they are unable, because they don’t have the resources, emotional energy or time, especially if they’re now taking on additional responsibilities such caring for children full time etc. The suggestions in this post are just that – suggestions – something to do if you are bored. They are not requirements or necessities. Should you feel that you’re under too much of a burden then try something else instead or – and this is important too – just try to rest. Please do not feel that you need to be productive. We should support everyone’s unique situation, rather than compare it our own response and responsibilities.

An additional disclaimer: I am, by no means, a coding expert. The coding languages I suggest are based on the fact that they can be used for universal tasks in academia (and beyond), and that they are simple enough to pick up and produce something useful without knowing the whole language. However, it’s unlikely I’ll be able to help with any specific problems! It’s also important to recognise that coding can be frustrating and time-consuming. Sometimes, it can be a case of a learning through a lot of trial and error, or you might find you copy code without ever understanding how it works. Both are fine and, if want to persevere, remember to be patient with yourself.

Below I’ve introduced three coding languages. To start, I recommend picking just one and setting yourself a small goal of what you would like to do with it. I find that it can sometimes be difficult to know where to start if you’re not really sure what you want to end up with!


1. LaTeX

Pronounced “Lay-tek”, LaTeX is a coding language that is used for preparing, formatting and producing written documents. It can be useful for putting together a formatted version of your preprint or writing your thesis. The bonus here is that, since it is written in code, the file size is quite small, which makes it less likely to crash when producing large documents. It is also great at integrating mathematical equations and figures, and integrates with reference management software to produce bibliographies. Perhaps most importantly, it uses a nice font(!)

The hardest thing about using LaTeX is knowing which software to use. There are several different apps (usually with ‘tex’ somewhere in the name) that allow you to write in LaTeX and compile a document. To be honest, I have no idea which one is best or indeed the difference between them (I use TeXShop). To start off with, I recommend using Overleaf, which is free for personal and uses a web-browser, so no need to download anything. They also provide a number of useful tutorials and walkthroughs to get started. There are also plenty of other research sites that you can find with a quick Google search. To begin with, you could try:

  • Producing a thesis cover page.
  • Producing a cover letter for a job application.
  • Writing your C.V.
  • Formatting a figure and figure legend.

2. R

R is a very powerful language that can be used for all types of statistical data analysis and presentation. All I know how to do with it, however, is how to turn an excel file into a graph. As R is so powerful, even the introductory resources can be quite complex and quickly dive-in to specialist terminology. I recommend this introductory workshop (still in early phases of being put together) by DataCarpentry. As a side-note they run some great workshops on a number of different coding languages and I would recommend attending if you get the chance. In addition, sometimes it’s best just to Google what you want to do, copy that code and learn yourself through tweaking it here and there. This approach isn’t so different from wet-lab research: imagine, for example, that R is your model organism and your knocking-in and knocking-out genes – with instant results! To start off with you could try:

  • Producing a bar graph and formatting the font, colours and axes.
  • Presenting some data as a box and whiskers plot.
  • Conducting some simple statistical analysis.

Whilst thinking about data presentation, please also take some time to read the excellent posts on data visualisation and statistics by Joachim Goedhart here on the Node.

UPDATE 01/04/2020: HarvardX Biomedical Data Science Open Online Training also has some great guides, including step-by-step Youtube walk-throughs.

3. HTML/CSS

HTML provides a basic language for producing websites and CSS is used to make them look better. Some fundamental knowledge of these can help when trying to customise your lab website or formatting a blog post. You don’t need any specialist software, you can just use Notepad or TextEdit to create the file (save the files with .html or .css and they’re converted automatically and will open in your browser), although some programmes do make it easier when starting out by colour-coding parts of code. Again, tons of material is provided online. A good start for learning HTML is provided in this tutorial from w3schools.com and the CSS intro is very good too. As always, Google is your friend. Why not experiment by:

  • Producing a simple homepage for a website?
  • Writing a blog post (for the Node, maybe?) introducing some HTML elements?
  • Presenting your data in a HTML table?
  • Customising an existing HTML file with your own CSS code?

If a group would like to start learning together, it might be a good idea to start a Slack group to support each other! If you have any other suggestions on languages to add to this post, please comment or add to the Twitter thread. For other suggestions for what to do outside of the lab, check out this great infographic from Dr Zoë Ayres. Why not write use your new skills to a post for the Node on one of these ideas?

Development and the COVID-19 pandemic

Posted by , on 23 March 2020

Last week, I and the rest of the Development team said goodbye to our lovely office, and a new era of remote working has begun. But we’re lucky – editorial work can (we hope!) proceed pretty much as normal from our desks at home. Of course, things are not so easy for researchers: shutting down a lab means a lot more than moving your monitor and keyboard to a new location and figuring out the best ways to maintain good communication with your colleagues.

Across the globe, normal life and normal work is on hold for the foreseeable future, and – while there are far more important things to worry about – this will inevitably impact on researchers’ ability to publish their work. The Development editorial team has been thinking about what we can do to support our community during this time, and we’ve just released the following statement (which you can also read here):

We are of course aware that the COVID-19 pandemic is having an unprecedented impact on researchers worldwide, with many labs shutting down either partially or fully. The Editors of all The Company of Biologists’ journals have been considering ways in which we can alleviate concerns that members of our community may have around publishing activities during this time. Here, we detail the actions we are taking at this point:

  • Any reviewer or author unable to meet deadlines set by the journal should contact the editorial office and we will be able to extend your deadline. Our Academic Editors may also be somewhat delayed in handling papers as they deal with pressing matters – we hope that all parties will recognise the need for increased flexibility with timelines during this period. Please note that reviewers will still receive automated reminders from our system, but these are not intended to put you under increased pressure so please just let us now if you need extra time. 
  • Our scoop protection policy means you don’t need to worry about being scooped once you’ve submitted your manuscript – even if your revisions take longer than expected. Moreover, we will not necessarily reject a new submission if a competing paper has just been published: in these cases, we encourage authors to contact us to discuss how to proceed.
  • We ask that reviewers bear in mind that authors may be unable to conduct experimental revisions for a paper. Obviously the journal needs to ensure that submissions are held to the same standards as usual, and that all conclusions drawn in a paper are supported by the data presented, but ask reviewers to limit requests for experimental revisions to those they deem essential for publication in the journal.
  • Where authors are concerned about their ability to respond to reviewers’ reports, we encourage you to contact the editorial office to discuss their revision further. Please send us a point-by-point response indicating where you are able to address concerns raised (either experimentally or by changes to the text) and where you will not be able to do so within the normal timeframe of a revision. The editor will then provide further guidance.

We hope these policies will help to support authors during these difficult times; we will continue to review the situation going forwards. Please don’t hesitate to contact the editorial office if you have any questions or concerns.

And at this time when many researchers are unable to conduct experiments, remember that Development welcomes the submission of purely computational or theoretical papers!

 

As many of you will be aware, The Company of Biologists also organises workshops and meetings that have been affected by the pandemic. All our events through to the end of July have been postponed, and we will continue to review the situation for events later in the year. We’re still hoping to be able to hold our ‘From Stem Cells to Human Development’ meeting in September, but recognise that no-one wants to be booking conferences at this time and so have made some changes to our deadlines and registration process – you can find more information on this here.

In these crazy times, communities (be they personal or professional) seem more important than ever – so while we won’t be meeting in person any time soon, I’m looking forward to seeing the innovative ways we’ll find to interact virtually, and I’d be happy to hear any ideas you may have about how Development and The Node can help with this. Feel free to comment below, get in touch on twitter (@katemmabrown1) or drop me an email.

And in the meantime, stay safe, stay at home and wash your hands!

BSDB/GenSoc 2020 – eTalks and Tweetorials

Posted by , on 18 March 2020

The BSDB/GenSoc meeting’s cancellation left organisers and us thinking about ways to try to replicate some of it online. Over on Twitter it’s been a blast – just look at #BSDBGenSoc2020 where you’ll find speaker profiles, poster sessions (which we also put on the Node: I and II), and lots of discussions. But what about talks? One option would have been to set up sessions of video conferenced talks – but we didn’t have the time, and even if we had, many if not most speakers have too much on their plate to commit to giving one. What we did instead was send out a call for people to submit their talks, in any form, and got a great response.

If you have any questions for the speakers and can’t find their contacts online, let us know and we’ll send the message on!

 

eTalks and teasers

 

Peter Sarkies – Epi-Evo: New insights into epigenetic regulation through evolutionary analyses

Peter used PowerPoint’s record function to give the talk he was due to give in the ‘Evolution of Development’ session.


 

Filipa Simões – New target identified for repairing the heart after heart attack

Filipa uploaded a video of her discussing the work she would have presented at the meeting (she also uploaded a poster).


 

Emma Rawlins – building and rebuilding the lung: insights from human lung development

Emma uploaded six teaser slides from the talk she was planning to give in the Human Development and Genetics session.


 

Andrea Streit – Cell fate decisions in the cranial sensory nervous system

Andrea uploaded a teaser slide of her talk that would have been in the ‘Gene Regulatory Networks in Development’ session.


 

Tweetorials

Usually used to go through new papers, the Tweetorial is just as good for presenting talks or posters!

 

Tim Fulton – Self-organised symmetry breaking in zebrafish reveals feedback from morphogenesis to pattern formation


 

Oluwaseun Ogundele – The role of chromatin remodellers in transcriptional response to extracellular signals


 

Alfonso Martinez Arias – Gastruloids: an ESC based model for mammalian gastrulation and body plan engineering

Part I

 

Part II


 

Jessica Forsyth – Describing the changing architecture of the preimplantation embryo using IVEN
