Do you tend to think that science is a body of unchanging factual information, and everything published in the scientific literature is correct? Read on…

Recently my favourite science blogger, Orac, provided links to a couple of videos that I think should be compulsory viewing for anyone interested in learning about critical thinking and the nature of science. So I’m going to give you the links through his website (because I’m pretty new to this blogging business and so far […]

One of the attributes of a successful student is the ability to integrate material from across the curriculum – pulling together knowledge from (say) genetics, evolution, and biotechnology into a coherent whole. Here’s an example of a recent paper that integrates biotechnology techniques and genetics to clarify our understanding of our own evolutionary past.
