Faux Pas in Researching

I chose to pick three sources discussing the subject of stem cells.

"The new challenge of stem cell: Brain tumor therapy," F. Colleoni and Y. Torrente.
This first source is one I chose from an academic journal I found from the HBLL's website. The journal, called Cancer Letters, is a collection of academic papers covering studies that have been researched concerning cancer. This article in particular is one that discusses stem cell and its importance in cancer research. As it was written directly by researchers from the Stem Cell Laboratory, whose specialty is stem cell research, the information is the most likely to be accurate.

The second source is an article from the New York Times which is in danger of being a more biased source, as it's written by a columnist. These articles are written to argue their opinion, and so statistics are often taken out of context, or important details left out.

The least reliable source is the article on stem cell research from Wikipedia.com. Although it would be useful to get an idea of the topic, because the article can be changed by anyone, it's not always the most accurate of information.
