A Level Biology: Interesting article on scientific studies

This article from Science, debating current research revealing links between Chronic Fatigue Syndrome and viruses, does a good job of highlighting how the scientific community self-regulates. It discusses research protocols such as sample selection and demographics, faults such as contamination and bias linked to commercial interests. I think it makes a good up to date discussion of how scientific studies are carried out and the need to produce clear and detailed articles. It is an easy read too and I highly recommend it:
