A few very good articles from the ever-reliable Katharine Mieszkowski in recent issues of Salon.

• "The triumph of fringe science" about global warming deniers in governement.
  
• "A textbook case of bad science" is another depressing article, this time about evolution deniers in schools.
  
• "Superbug to the rescue!" is about using genetically modified organisms to help clean up pollution. Or not.
