This is JosephI was reading Mike the Mad Biologist's web page and I noted this article on Ebola and the flu.  Ebola has been in the news a lot but influenza remains a bigger killer than Ebola:Ebola has claimed fewer than 4,000 lives globally to date, none in the United States. Flu claims between 250,000 and 500,000 lives every year, including over 20,000 in the United States—far more American lives than Ebola will ever claim.Notice just how terrible the Spanish flu was:It infected 500 […]

A cardiovascular group has retracted a conference proceeding abstract, because it too closely resembled a paper they published prior to the conference. The last author is baffled as to why the journal couldn’t have made that call before they published the abstract. Here’s the notice for “Increased beta-adrenergic inotropy in ventricular myocardium from Trpm4 knockout […]

This one’s a real mess. In June, a paper in Tumor Biology was retracted for at least four reasons, including bad data and hiding a trial sponsor (Merck). Some people who contributed work weren’t cited; at least one author had no idea his name would be on it. And that’s just what they tell us in the notice. Here’s the […]

...or at least ask a follow-up question.Maybe it's just me, but don't journalists have an obligation to object when sources say something blatantly, laughably untrue? If the subject of an interview has just insulted the intelligence of your readers, should you at least attempt to get a more truthful response?Andrew Cuomo has a new book out. To promote it he has a brief interview with Amy Chozick in the New York Times. I realize that this isn't a setting where you expect hard-hitting […]

[picking up where we left off here]David Brooks has one of the most desirable jobs in journalism; it is also one of the most difficult. He has to present a mainstream conservative perspective in a way that appeals to his center-left target audience (which includes but is somewhat larger than the target audience of the New York Times). His job is greatly complicated by shifts in the Republican Party and the conservative movement. On a growing number of issues there is less and less common ground […]

There’s a new journal in town. Inference’s first issue includes a lengthy review of a laboratory by a tennis instructor, a set of caricatures, and an exchange of emails from 1996 that is “perhaps, less remarkable for what it says than for the fact that it took place at all.” In short, its editors — […]
