Check out this recent post by another Science blog. He claims the media often gets Science news wrong because they know nothing about the subject and interject sensationalized words into the articles.
Unfortunately, science reporting is pretty poorly done most of the time. Written by people that have very little knowledge about science, and don’t ever actually read the original journals where the studies they are discussing originate. Places like Science Daily source them at the bottom of articles and should be checked for science much more than with any other form of news story IMO.
