For those of you who read the previous post about LaTeX and are interested in giving it a go, but just don’t know where to start, this article should get you on your feet. I used LaTeX to write my thesis and was (mostly) self taught, so I know how scary it is to begin…
Every once in a while a big case of scientific fraud reaches public attention. Does that mean these well-known cases are exceptions, a few rotten apples…or might the rest of the fruit bowl also be affected? A major part of a scientist’s work is to secure funding for future research. Obtaining funding is strongly connected…
Having to make stock solutions is a part of everyday lab life…a tedious, but necessary, one. So why not make the process as streamlined as possible? Here are a few little tricks I picked up while I was still in the lab: Check to see if anybody has a tried and tested recipe – why…
To become an expert in managing people and projects together, a scientist needs a variety of important skills to succeed. One way to add to an already impressive skill set is by mentoring others through internships. Students take internships to be exposed to new things. Mentors give internships to inspire others to do research. They…
After years of hard work in the lab, having to sit down and write everything up can be a daunting and difficult task. Here are a few tips that I picked up during my thesis write-up that might help to make the process that little bit easier. Back up This is probably the advice most…
Keeping up with the latest developments in your field of research is important whether you are taking a sabbatical to travel the world or your funding has finally dried up. Whatever your situation, it is good to maintain a broad working knowledge of your field of interest and not leave yourself a mountain of reading…
Let’s face it: when you said you read that paper, what you really meant was that you read the abstract. And that conference you went to? You probably scanned the abstracts of the posters instead of actually attending the poster session and chatting with the presenters. It’s a dirty little secret and a time-saving tool…
Every scientist, at one time or another, has avoided meetings with their PI. They are, however extremely important in shaping the direction and progress of your project. Having regular productive meetings with your PI will help maintain a positive working relationship and contribute to the success of your project. Keep the following in mind when…
Most scientists I know approach the publication process with fear and trembling: the endless discussions about what journal to submit to, the agonized consideration of impact factors, comparing the all-important “time to first decision”, etc. Now that I’ve been working for a scientific publisher for a few months, I’m surprised at how many manuscripts still…
For scientists, Photoshop is a double-edged sword with a dagger nailed to the hilt. Its power in image processing is unrivalled; its ability to gut you with ethics violations is unmatched. An earlier article outlined how to keep your conscience clean when Photoshopping, here we offer four tips that will help walk with the Photoshop balancing…
Like many scientists, I don’t consider myself a statistics expert. But I am determined to do things right in my science, and that includes statistics. In my experience, a lot of scientists who are “scared” of statistics fall into the trap of ignoring the existence of anything beyond a t-test. But using the right method…
What comes to mind when you think of good laboratory practices? To many, good laboratory practices describes the best conduct while working at the bench. The laboratory is a complex environment and understanding how small, seemingly innocuous, actions can have such a huge impact on the outcome of an experiment will help you to ensure…
The very idea of standing up and giving an oral presentation at a conference gives even the most confident of us butterflies. Additionally, I don’t know many scientists who find the thought of spending hours working on a powerpoint presentation exactly thrilling. However, there are many benefits to presenting your work at a conference. First…
How often have you torn apart the lab looking for the reagent you need right now for some thawing samples? That reagent which you (possibly) ordered a week ago and which (maybe) came in yesterday? If your answer isn’t “just once in my entire career,” please read on! I will outline four steps to setup…
It’s pretty likely you’ll have heard of impact factors, either through colleagues talking about them in the lab, or from a journal homepage advertising its latest score. Whilst impact factor is a relatively artificial value, it is something that journal editors, scientists and some funding agencies take seriously. It’s therefore important to understand what it…
Graduate programs in science can take an additional four to seven years beyond a Bachelor’s degree. That’s a lot of time to commit to advanced training! If you’re currently a high school or college student wondering if graduate school is the right path for you, perhaps an internship in a laboratory can help you decide….
Following closely on the heels of Cristy’s article “How to Clean a Waterbath”, I’d like to take a moment to rant about a few other hated (and carefully avoided) lab tasks. Here are my top ten LEAST favorite things to do in the lab: Cleaning out the vacuum trap – truly gag-worthy…you never know what…
Poster sessions can be your best friend, or your worst nightmare; it all comes down to how well you’ve prepared. In this article, I’ll discuss how to present your data in poster form, what to look out for at a poster session, and how to make the most out of a poster session…in short, how…
Here’s a quick guide to cleaning and maintenance, to help you overcome your fears of the monsters lurking in your water bath.
Everybody is different when it comes to how they like to run their work space. Some people just find a space in the lab and work wherever there’s room, sharing their tips and pipettes, while others like to have a designated area to do their lab work in, with their own equipment. Personally, I much…
There are six little words that can instill both excitement and trepidation in the heart of a graduate student: “No one’s ever done this before.” What those words really mean, of course, is “No one’s ever published this before,” and you are either standing at the edge of a great discovery or a chasm of…
In today’s technology-driven world, we leave so many things to our electronic gadgets. Surprisingly, many life scientists try manically to control the appearance of their documents by hand with programs like MS Word. LaTeX takes this task off your hands by providing highly efficient algorithms to properly format your texts. The results are almost always…
The easiest way to keep abreast of what’s going on in your scientific field is to set up a PubMed alert. We show you how.
You have just finished your undergraduate studies, or perhaps you have been working in the field for a while, you are full of energy and zest and you want to prove to the world that you are carved from the right stone to pursue PhD studies. Going to graduate school is a very important, potentially…
Against the advice of journals and printers, many scientists use Microsoft Powerpoint to assemble posters and figures. You should consider upgrading to Adobe Illustrator! For generating scientific figures, Illustrator is more powerful and flexible than Powerpoint and is designed to produce print documents at high quality resolution. This means that journals will stop sending your…
Collecting the data took several years, writing the paper took several months, assembling the figures took several weeks, and converting those figures to PDFs took a frustratingly long day. You waited a month for the paper to come back from review, then two months re-doing experiments to satisfy a sadistic reviewer. Finally, your paper is…
To pull together our discussions so far on hypothesis testing and p-values, we will use the t distribution as an example to see how it all works. The t distribution (you may have heard it called Student’s t) is a probability distribution that looks like a bell-shaped curve (or normal distribution). If we sample repeatedly from…
Now we come to the third part of our trifecta; in the last two posts I have gone over p-values and how they determine significance in null hypothesis testing, and we talked about degrees of freedom and their effect on the p-value. Finally, we come to pseudoreplication: where it can all go terribly wrong. Replication…
In the previous article in this series, we covered teamwork and networking. Now it’s time to move on to what many people consider the most boring part of the lab work: the analysis. I know we all wish that a simple histogram or a rather nice-looking Western blot or PCR would suffice. But the fact…
In the last post I talked about p-values and how we define significance in null hypothesis testing. P-values are inherently linked to degrees of freedom; a lack of knowledge about degrees of freedom invariably leads to poor experimental design, mistaken statistical tests and awkward questions from peer reviewers or conference attendees. Even if you think…
In previous articles, I’ve primed you on hypothesis testing and how we are forced to choose between minimising either Type I or Type II errors. In the world of the null hypothesis fetish, the p-value (p) is the most revered number. It may also be the least understood. The p-value is the probability, assuming the…
Before starting any new research project, it’s essential that you have as complete an understanding as possible of the current research literature. Knowing what other people have done will prevent you from duplicating existing work, and will perhaps indicate under-explored niches. If you work in the same subject area over a number of years, you…
You have been toiling away at your thesis project for years and you think the end is in sight. Now the big question is “What’s next?” If you think you might want to move away from the bench, then you should check out our suggestions for alternative careers for scientists. If you think your future…
Merriam-Webster defines networking as “the cultivation of productive relationships for employment or business”. Less formally, networking is actively communicating with the other people you know (mostly scientists, in our case) for career advice and job openings, in addition to utilizing opportunities to meet new people for the same purpose. This is a core activity of…
Several years ago as a freshman in a research lab, the very first project I received was to pipette incremental micro-volumes of H2O onto a piece of parafilm. Boring! Weighing the liquid on parafilm and comparing the weight between 10 replicates for each micro-volume continued for a week before I touched anything else in that…
You might be proud of your pipetting skills (if not, check this article on how to stop pipetting errors from ruining your experiments) and be churning out data faster than a liquid handling robot, but beware… you might also be pipetting yourself out of a job. I almost did. Pain due to pipetting is common….
Everyone loves a bargain! These days, more and more labs need to stretch every dollar as far as it will go. So how do you keep your lab well-supplied on a tight budget? To get a better deal on products you might choose to shop around, buy in bulk or haggle with vendors. However, if…
They say scientists are highly skilled… and rightly so! While many people would think that we’re shy, retiring types who sit at our lab benches obsessing over teeny-weeny molecules, science (and particularly the process of obtaining a PhD) sets us up as highly skilled members of the workforce. I can hear you all groaning as…
This column is loaded with pop quizzes for you to test yourself on. If you haven’t already done so, catch up on yesterday’s piece on hypothesis testing for a refresher. Take a gander at the table below for a summary of the two types of error that can result from hypothesis testing. Type I Errors occur…
Hypothesis testing is the foundation around which we prove our science is worth funding, publishing and sitting through a conference presentation for. I can’t overstate the importance of understanding hypothesis testing, such is the integral part it plays in biological analyses. The Null Hypothesis Fundamental to statistics is the concept of a null hypothesis, and…
