If you have surfed the interwebz in the last five years, chances are high that you would have stumbled upon one of Amy Cuddy’s articles or talks about ‘power posing’. Admittedly the argument that she weaves is actually convincing, and the simple fix she suggests to help with stressful situations most compelling. But what part of this claim is actually evidence based research, and what part is abusing authority to stretch scientific truth?
One thing that regularly stumps scientists is the handling of data. We seem to be very good at generating obscene amounts of it, but representing it meaningfully can be a little off putting if you don’t happen to be a bioinformatician. Let’s continue our tutorial series by introducing Two-Sample t-Tests and Paired t-Tests to see how we can easily incorporate statistical analysis into our work.

For all you car owners out there, doesn’t it drive you crazy not knowing what the heck you are filling your cars up with? Well, stop wondering and start learning about the composition of fuels and how its chemistry affects the performance of your car!
Like many others out there, I require at least one cup of coffee a day to function – in fact I am drinking a cappuccino as I type this. Interestingly, there is more chemistry involved in the brewing and consumption of coffee than just getting your caffeine fix. We also explore death by coffee, because that’s what the masses want. Right?
Technically speaking, a human penis can’t actually be ‘broken’. That’s because it’s made up not of bone, but of soft, spongy tissue. But what about animals? Do our close and not-so-close relatives possess boney penises? And if so, what is the function of a penis bone? The answer isn’t as simple as you might think.
Virtually all scientific reports and articles deal with numbers of some sort, and what better way to represent large amounts of data than on a well made graph? Unfortunately not all graphs are created equal; this post will introduce the basics of graph building and common pitfalls to avoid.
