4:51 PM | What it's like to be a woman in social media
An excellent article about Mary Beard, the famous classicist, is in this week's New Yorker. It is informative to have a prominent academic give an account of her life experiences like this. I want to encourage others to read the original article, but will pull out one salient and topical...

1:00 PM | Netflix and the ethics of modern journalism
I had meant to drop this topic after the recent Emmys post, but one more issue got stuck between my teeth and I think it would be easier to write it away then to try to ignore it.I recently heard an interview on public radio that bothered me quite a bit but before I get into the specifics I should probably lay some groundwork about the Netflix business model.When Netflix first started as a DVD-by-mail service, perhaps its greatest selling point was selection. It couldn't offer every movie and […]
12:56 PM | Danish committee rejects much of Klarlund Pedersen’s appeal of misconduct findings
The Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU) has partially reversed a December 2013 finding of misconduct against a scientist in Denmark, but has upheld most of its ruling. Bente Klarlund Pedersen, whose case was tied up with that of Milena Penkowa, another scientist in Denmark found guilty of misconduct, committed misconduct in […]
11:00 AM | WS MoreOrLess: Do We Use Only 10% of Our Brains? 29 Aug 14
Is it true that humans use just 10% of their brains? It’s the premise of the new film Lucy, in which the brain capacity of Scarlett Johansson’s character increases to dangerous levels. Tim Harford uses considerably more than 10% of his brain to separate the neuro-science facts from the fiction with Professor Sophie Scott. What drives the price of footballers? Tim Harford tries to understand the huge transfer fees with Raffaele Poli from the CIES Football Observatory and football […]

1:19 AM | Barry Ritholtz on Market Timing, Wolf Richter on rigging the IPO market
I don't have the time to do anything more than pass these along (and Joseph has even less), but these are worth your time.First, Barry Ritholtz  looks at the upper and lower bounds for returns on market timing strategies and comes up with some interesting conclusions.Second, Wolf Richter shows how a carefully placed (and even more carefully leaked) investment of $20 million has caused the valuation of a company with no revenue and virtually no business plan to go from an […]

8:40 PM | Q: Before you open the box, isn’t Schrödinger’s cat alive or dead, not alive and dead?
The original question was: If I don’t open the lid of the bunker, the cat inside is either dead OR alive.  Why does Schrödinger say that the cat is both alive AND dead if I do not perform the act of … Continue reading →
1:45 PM | Weekend reads: DIY peer review, wildly exaggerated breakthroughs, and how to commit fraud without being caught
Another busy week at Retraction Watch. Here’s what was happening elsewhere: “…as I am the first author of this manuscript…it would probably be better if someone else performed the review.” Keon West on “the strangest e-mail I’ve had to send in a while.” Of course, he could have just done his own peer review. “…most […]
5:00 AM | Il problema di agosto (552) – Wimbledon 2.0
Ma vi rende conto? Rudy che non sa neppure che a Wimbledon è assolutamente irrinunciabile vestire di bianco! Dobbiamo davvero vederle tutte, in questa vita faticosa. Oddio, va riconosciuto a Rudy che, a ben vedere, non è che si trattasse davvero di Wimbledon: anche perché, se si fosse trattato davvero del praticello inglese, assai difficilmente avremmo [...]

6:19 PM | Statshot: Large Weddings, Burning Man and College Football
In this week's statshot: A new study finds that large weddings seem to mean happier marriages; since Burning Man started, the annual weeklong desert festival has grown so much that it temporarily becomes the sixth-largest city in Nevada; and big-time college football will now have a four-team playoff.
5:55 PM | Comet Landing Like Trying to Put a Toy Helicopter on a Leaking Balloon
The Rosetta space probe made history this month when it became the first mission to orbit a comet. The trip took a dozen years, covered 4 billion miles, and required four gravity slingshots to control the satellite’s speed and trajectory.

3:31 PM | MoreOrLess: How Deadly Is Ebola? 29 Aug 14
Media reports are suggesting that as many as 12,000 people may have Ebola in West Africa, but experts tell More or Less that's not the case.

Courtesy of The Australian, we have an update on a story we first covered in late 2012.

1:00 PM | One of the most important aspects of Common Core gets relatively little attention
“No one ever went out to lunch with Mushari. He took nourishment alone in cheap cafeterias, and plotted the violent overthrow of the Rosewater Foundation. He knew no Rosewaters. What engaged his emotions was the fact that the Rosewater fortune was the largest single money package represented by McAllister, Robjent, Reed and McGee. He recalled what his favorite professor, Leonard Leech, once told him about getting ahead in law. Leech said that, just as a good airplane pilot should always be […]

3:30 PM | Déjà vu: Double pub in the same issue earns a retraction
Always do a careful reading of your galleys, editors. We imagine readers of Biomedical Chromatography’s special issue, “Reminiscences of Chang Kee Lim,” did some flipping back and forth when they found the same paper published twice. Here’s the resulting notice for “Determination of 4-hydroxy-2-nonenal in serum by high-performance liquid chromatography with fluorescence detection after pre-column derivatization using […]
