Tips for Choosing Your Lab Notebook Pen (and Why You Need to Choose Carefully)
Keeping a meticulous lab record of your experiments is a necessity. And it’s drilled into us to back up our computers, including backups stored in different locations to ensure vital records don’t get lost. But how do we protect the hard copy information in our lab books? You may not have given much thought previously…
Genomic Analysis of Single Cells: The Benefits of Being Single
You don’t need to be told about how next generation sequencing technologies have revolutionized the way we study the genome and the epigenome. Whether you want to look at transcription (RNA-seq), translation (Ribo-seq) genomes (DNA-seq), interactions of proteins and DNA (ChIP-Seq) or to study epigenetic features such as methylation (whole genome bilsulfite sequencing) there are…
Common Sins When Publishing Your Paper
When it comes to publishing your paper you want to show the world what excellent research you’ve worked so hard to produce. Part of that is providing enough detail so that others can reproduce your work and take it further. There are certain details you need to include in your paper; many, but not all…

A Picture Speaks a Thousand Words – Making Diagrams Simple
Figures play a central role in science not just as a way of displaying results, although this is obviously important, but also as a way of getting across complicated theories and processes in a relatively simple and direct manner. I’m a firm believe in the power of putting ideas into diagrams and spent a considerable…
Let’s Talk About Stats: Getting the Most out of your Multiple Datasets with Post-hoc Testing
So you’ve performed a test such as an ANOVA and have found that there is statistical significance in your data (lucky you!), however you now want to know where that significance lies. When you are comparing multiple sets of data it might seem like a logical thought to simply perform an individual t-test between each…
Let’s Talk About Stats: Comparing Multiple Datasets
Last week I focused on the left-hand side of this diagram and talked about statistical tests for comparing only two datasets. Unfortunately, many experiments are more complicated and have three or more datasets. Different statistical tests are used for comparing multiple data sets. Today I will focus on the right side of the diagram and…
Let’s Talk About Stats: Comparing Two Sets of Data
There are so may statistical tests out there it can be difficult to determine which is the right test to use. Below is a simple diagram to help you quickly determine which test is right for you. Although this is by no means a comprehensive guide, it includes some of the most common tests and…
Let’s Talk About Stats: Understanding the Lingo
The first hurdle in learning about statistics is the language. It’s terrible to be reading about a particular statistical test and have to be looking up the meaning of every third word. The type of data you have, the number of measurements, the range of your data values and how your data cluster are all…
Avoiding Plagiarism in Science
I remember when I first learned about plagiarism during my undergraduate course. The lecturers were so firm in telling us that if we got caught plagiarizing we would face serious repercussions and that all our work, especially our dissertations, would be vigorously checked by plagiarism detecting software. I was so panicked that I would inadvertently…
The Ten Lab Commandments: Or the Guide to a Happy Lab
I was lucky enough to do my PhD in an extremely friendly and well-organised lab. In my opinion, these two key traits are required for a successful research experience. This environment, while appearing effortless, was due in part to the hard work of the senior postdoc who kept the lab, and all of us, in…
A Guide for Solving Your Lab Math Problems
Math is an important part of lab life, from making solutions to calculating protein concentrations, and miscalculations can cause mayhem for your experiments. Therefore it is important that your math is right, or you could spend weeks trying to figure out what’s going wrong in your experiments. I was hopeless at remembering how to do…
10 Tips For Organizing Your Lab Book
Writing your lab book is easy to put off as it never seems quite as important as splitting your cells or running that gel. I’m sure, like me, you’ve said to yourself it’s fine if I leave it for a day or maybe even a week, as I’ve got all my notes to work from.…
Conrad Waddington and his epigenetic landscape
I was first introduced to Conrad Waddington’s epigenetic landscape when reading ‘The epigenetic revolution’, a fantastic introduction to epigenetics, and in my opinion, a must read for anyone who is looking for an entertaining and enjoyable introduction to this fascinating field. In his model, Waddington likens the process of cellular differentiation to a marble, which…
Useful Tips to Keep on Top of New Literature
It’s a gut wrenching feeling to come across a paper that impacts your work, and even worse when it turns out the paper is weeks or even months old. Perhaps finding that paper earlier would have saved you time with your experiments or change the direction of your project. It used to be (long before…
