By now, many of you will have heard of the recent Lancet study which claims that over 650,000 Iraqis have died due to the actions of the Bush administration. The paper is available online as a pdf. I haven't as yet had a chance to read the paper (still grading), but will just note that even if the estimate is too high, it is probable that the official estimate is too low. For further commentary by SciBlings see: Mike Dunford, Mark Chu-Carroll [here and here], Mike the Mad Biologist, Tim Lambert, and I'm sure others.
billmon has an interesting look at the study and the reactions to it over at http://billmon.org/archives/002822.html
