The number of tornadoes recorded by the National Climatic Data Center has increased in recent years, but that doesn’t mean there have been more twisters.

5:50 PM | Have you had your flu shot yet?
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 […]

5:29 PM | Talking to Your Phone, Dining Out and Slower Runs (Statshot)
American teens don’t use smartphone voice-recognition technology much more than adults do overall, but they use it in different ways. Homemade meals make up almost 20% less of our calorie intake than they did 35 years ago. The jump in marathon participation has brought with it a sharp increase in average finishing time.

3:30 PM | Heart paper will go on, but only in the first of two journals it was published in
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 […]

1:30 PM | Failure to disclose drug company sponsor among litany of reasons for cancer retraction
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 In June, a paper in Tumor Biology was retracted for at least four reasons, including bad data and hiding a trial sponsor (Merck).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 […]

1:00 PM | When journalists have an ethical obligation to roll their eyes...
...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 […]

2:30 PM | Authors retract PNAS paper questioned on PubPeer after original films can’t be found
PubPeer leads the way again: The authors of a paper about Parkinson’s disease in the Proceedings of the National Academy of Sciences (PNAS) have retracted it, several months after a commenter highlighted the exact issue that led to the article’s demise.

1:00 PM | David Brooks, con(firmation) artist
[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.

Marc Andreessen has a new interview up and it is characteristically packed with silliness.
