BIAS EVIDENT IN MEDIA


Emails to government officials saying a terrorist group had claimed responsibility were written about by two news agencies, but with very different perspectives.
            Fox and NBC both reported on the emails, which said that a group named Ansar Al-Sharia had claimed responsibility for the attack on the American embassy in Libya, in which four Americans died.
            The NBC report had the headline, “U.S. officials: Benghazi emails reveal little new about attack response.” The first paragraph explains about the emails, while the rest of the article appears to be a thinly veiled attempt to make the reader doubt that this intelligence could be relied upon.
            The Fox headline read, “Lawmakers press administration for Libya answers after email release.” To their credit, the article did state that the group later denied the claims, but bias shows up here as well. The article didn’t spend much time on the emails, but instead spoke more about how the administration’s initial explanation didn’t match up with later intelligence.
            Overall, both sides appear to be trying to persuade the reader to believe something, instead of just reporting the news.

NEW FUNCTIONS OF DNA DISCOVERED

A new genetic discovery has big implications for medicine and scientific thought.
Scientists previously thought that only one or two percent of the genetic code was actually used. The research group ENCODE (Encyclopedia Of DNA Elements) recently published findings that at least 80 percent of DNA is chemically active.
"The genome is just alive with stuff. We just really didn't realize that beforehand," said Ewan Birney, one of the leaders of the project, in an article of The Sydney Morning Herald. ENCODE discovered that the majority of genes act like switches which activate or deactivate a command to build a specific protein structure.
It works like this: cells are made of proteins. DNA tells the proteins how to fit together to build the cell. Activate certain switches and the DNA will tell the proteins to build a kidney cell. Activate a different set of switches and you will get a blood cell, and so on.
The research also indicated that diseases such as diabetes and some kinds of cancer have a lot to do with genes. That means that if scientists discover how to manipulate the gene switches, it could lead to incredible breakthroughs in medicine.
"Most of the changes that affect disease don't lie in the genes themselves; they lie in the switches," said Michael Snyder, a Stanford University researcher in an interview with The New York Times.
