The release of the trailer for The Principle, a geocentric film casting doubt on Copernicanism, resulted in statements from several people featured in the trailer distancing themselves from the project. Narrator Kate Mulgrew explained on Facebook that she was misled about the nature of the project and that “I am not a geocentrist, nor am I in any way a proponent of geocentrism.” Physicist Lawrence Krauss reasoned that producers either purchased footage of him from another production company, interviewed him under false pretences, or used public domain footage. With regard to the latter, producer Rick Delano said in a released statement that “I can tell him how he ended up in our film. He signed a release form, and cashed a check.” Robert Sungenis, the film’s executive producer, is a geocentrist, running the galileowaswrong.com blog.

“Language diversity” correlates both with mountainous terrain that isolates human groups and with rivers that bring those groups together.

Jenny McCarthy argues in an op-ed piece for the Chicago Sun-Times that she is not and has never been against vaccines. Phil Plait provides an excellent argument to the contrary, but I’ll add that her backtracking might have been motivated by the resurgence of preventable disease outbreaks, grimly documented in the Jenny McCarthy Body Count website.

Kansas is not planning to black out the science program Cosmos, despite the viral popularity of the satirical news story.

Here’s a roundup of the best April Fool’s Day hoaxes from around the web, and another one focused on the science/library community. But NPR’s prank is the clear winner.

“You don’t think of the Bible necessarily as a scientifically accurate source of information, so I guess we were quite surprised when we discovered it would work. We’re not proving that it’s true, but the concept would definitely work”: Physics students at the University of Leicester have determined that Noah’s ark would indeed be buoyant.

Don’t tell Mr. Toad: A new study suggests that children retain less information about animals from anthropomorphized accounts. But kids learn more when science is packaged in a music video.

We don’t have stasis fields yet, but in a new clinical trial, gunshot or stabbing victims will be placed in suspended animation (induced hypothermia) while doctors repair damaged organs. [via Marginal Revolution]

Eliminating invasive species is more difficult than we realize, as is even labelling them “native” or “alien.”

Conflicting with previous results, a new study supports the 5-second food rule.

The end may be nigh, according to a NASA-funded study of past complex civilizations employing both natural and social scientists. The paper, which will eventually be published in Ecological Economics, points to resource overexploitation and economic inequalities as the harbingers of doom, but offers a silver lining: structural changes or policy initiatives could stave off societal collapse.

Say goodbye to dessert: the WHO proposes limiting added sugars to 5% of caloric intake, or around 6 teaspoons of added sugar per day for the average person, halving their previous recommendation. But not to worry; if Virginia Tech professor Y.H. Percival Zhang’s research can scale up, we’ll all be eating starch from wood chips and other currently-inedible plant parts.

A 43% reduction in American childhood obesity has been reported across multiple news outlets, but some question such striking results. Mark Liberman at Language Log has done some digging and suspects both the statistical treatment of reference population growth charts, as well as changes to the sampling method which result in a more racially-inclusive population.

We eat too much of everything… except yogourt: the FDA has proposed new serving sizes for several types of food to better reflect actual consumption habits.

“Professors, We Need You!” Nicholas Kristof argues in the New York Times that professors need to make themselves relevant in real-world debates. Professors argued back that they already do, and that they might be better off staying in the (shrinking) ivory tower: for one thing, there are no FBI background checks.

Food research is notorious for flip-flopping, but studies suggest that consumers of whole milk and butter are less likely to be obese. NPR explores this “full fat paradox.”

“These gender differences that everyone knows exist, and they know they’ll always exist and they’re biological — when I started pressing on them I found that a lot of those assumptions hadn’t really been tested.” New York Magazine interviews psychologist Terri Conley, whose work debunks evolutionary explanations for men and women’s sex preferences.

One in four Americans believes that the sun revolves around the Earth, according to the results of a NSF survey presented at the recent AAAS meeting. But according to Time magazine, Europeans fared even worse on that question, with one in three responding incorrectly.

Despite an outpouring of protest and offers of rehousing, Copenhagen Zoo killed its “surplus” male giraffe Marius, and then performed a public autopsy with children in the audience. Meat from the corpse was fed to the zoo’s lions. Marius’ death has sparked discussion on the ethics of zoo conservation, with some blaming the zoo’s actions on Denmark’s pragmatic culture.

The health outcomes of people living in food deserts, areas without access to fresh food and which have prompted healthy eating initiatives, aren’t improved by improving access to fresh food; some researchers even believe food deserts aren’t the issue but that the cumulative stress (allostatic load) caused by long-term poverty is responsible for illness. Nutrition is a confusing field with a ”dysfunctional research establishment.” All we know without a doubt is that Americans really love pizza.

A report commissioned by The Beer Store, Ontario’s beer retailer, claims that beer would become more expensive if customers could purchase it at convenience stores. But the author of a previous study commissioned by the Ontario Convenience Store Association disagrees.

What should a first-semester, first-year, part-time, mature psychology MA student do upon discovering faulty math in an extremely popular paper in American Psychologist claiming that complex fluid dynamics proves that a ratio of 2.9013 positive to negative emotions is the tipping point for human flourishing? Well, if you’re Nick Brown, you team up with Alan Sokal and psychologist Harris Friedman and publish a takedown in the same journal.

Much has been written about Stephen Hawking’s black hole U-turn, prompted by his submission of a paper to arXiv claiming that “there are no black holes.” But as PopMech points out, Hawking’s quote continues with “—in the sense of regimes from which light can’t escape to infinity. There are, however, apparent horizons which persist for a period of time”: Hawking is weighing in on a debate about event horizons. And to top it off, the Borowitz Report posted a satirical column wherein Michelle Bachman claims that Hawking’s reversal means we shouldn’t believe climate or evolutionary science, which quickly went viral. [via Gizmodo]

Children’s “weight fate” may be set as early as kindergarten: according to a new study in the New England Journal of Medicine, overweight 5-year-olds are much more likely to be overweight as teenagers.

Why do dogs romp in the snow? Because it’s fun, of course!

Acclaimed biologist Lewis Wolpert has apologized for using the unattributed work of published papers, websites, and Wikipedia in his 2011 popular science book on ageing, You’re Looking Very Well, which has now been withdrawn by his publisher Faber & Faber. Wolpert, in his 80s, also included unattributed material in a not-yet-published manuscript, Why Can’t a Woman Be More Like a Man? This case joins other recent high-profile cases including Jane Goodall’s Seeds of Hope (plagiarism) and Jonah Lehrer’s Imagine: How Creativity Works (quote fabrication).
