Jason Koebler, reporting for Motherboard: You may have seen a viral headline floating around over the last few days: Apple recycled $40 million worth of gold last year, which was extracted from iPhones. Almost none of what was reported is true. [...] Here is the truth: Apple paid independent recyclers to recycle old electronics -- which were almost never Apple products, by the way -- because it's required by law to do so. Far from banking $40 million on the prospect, Apple likely ended up taking an overall monetary loss. This is not because Apple is a bad actor or is hiding anything, it's simply how the industry works. All electronics manufacturers that sell products in the United States are required to do e-waste recycling under laws enacted in 25 states. The laws are different in each state, but none of them require Apple to recycle Apple products. Instead, they usually require manufacturers to recycle a certain amount of pounds of e-waste, which is linked to either their market share or to the overall weight of products they sell. That's why you see Apple noting that it recycled "71 percent of the total weight of products we sold seven years earlier."

An anonymous reader writes: A new study from NASA finds global warming is shifting the way the Earth wobbles on its polar axis. Melting ice sheets are changing the distribution of weight on Earth, which has caused both the North Pole and the wobble, called polar motion, to change course. Since 1899, scientists and navigators have been accurately measuring the true pole and polar motion and for almost the entire 20th century they migrated a bit toward Canada. That migration has changed with this century -- now they're moving toward England, said study lead author Surendra Adhikari at NASA's Jet Propulsion Lab. "The recent shift from the 20th-century direction is very dramatic," Adhikari said. NASA scientist and the study's co-author Eirk Ivins said, Greenland has lost on average more than 600 trillion pounds of ice a year since 2003 and that affects the way the Earth wobbles in a manner similar to a figure skater lifting one leg while spinning.

__roo writes: Did you know chocolate helps you lose weight? You can read all about this great news for chocoholics in the Daily Star, Daily Express, Irish Examiner, and TV shows in Texas and Australia, and even the front page of Bild, Europe's largest daily newspaper. The problem is that it's not true. A researcher who previously worked with Science to do a sting operation on fee-charging open access journals ran a real—but obviously flawed—study rigged to generate false positives, paid €600 to get it published in a fee-charging open access journal, set up a website for a fake institute, and issued press releases to feed the ever-hungry pool of nutrition journalists. The doctor who ran the trial had the idea to use chocolate, because it's a favorite of the "whole food" fanatics. "Bitter chocolate tastes bad, therefore it must be good for you. It's like a religion."

Bennett Haselton writes: I can't stand switching from a slideout-keyboard phone to a touchscreen phone, and my own informal online survey found a slight majority of people who prefer slideout keyboards even more than I do. Why will no carrier make them available, at any price, except occasionally as the crummiest low-end phones in the store? Bennett's been asking around, of store managers and users, and arrives at even more perplexing questions. Read on, below.

stephendavion (2872091) writes "Chinese aircraft manufacturer China Aviation Industry General Aircraft (CAIGA) has started trial production of its TA600 amphibious aircraft, claimed to be the world's largest of its kind. With an expected maiden flight late next year, the Chinese plane would replace Japan's ShinMaywa US-2 short takeoff and landing (STOL) aircraft as the largest of its kind globally." Take a look at a side profile illustration of the CA-600, on this Korean language page. The TA600 has a huge maximum takeoff weight of 53.5 tons, but looks a bit puny compared to Howard Hughes' H-4 Hercules.

Bennett Haselton writes "What advice would you give someone who just bought a new laptop? What would you tell someone about how to secure their webserver against attacks? For that matter, how would you tell someone to prepare for their first year at Burning Man? I submit that the metric by which we usually judge tech advice, and advice in general, is fundamentally flawed, and has bred much of the unhelpful tech advice out there."

sagecreek writes "You can judge this book, at least in part, by the lengthy tagline on its cover: 'Learn to make practical, unique, real-world sites that span a variety of industries and technologies with the world's most popular mobile development library.' jQuery might not be your favorite framework on the long, long list of JavaScript possibilities. But Shane Gliser unabashedly describes himself as a jQuery 'fanboy...if it's officially jQuery, I love it.' Gliser is an experienced mobile developer and blogger who operates Roughly Brilliant Digital Studios. He also has some background in mobile UX (user experience), and both qualities show in this smoothly written, well-illustrated, 234-page how-to book that focuses on jQuery Mobile, a 'touch-optimized' web framework for smartphones and tablets." Read below for the rest of sagecreek's review.

Nerval's Lobster writes "Nate Silver, famous for applying rigorous statistical methods to U.S. political elections, has focused his predictive powers on a somewhat more lighthearted topic: this weekend's Academy Awards. As part of his predictive analysis, Silver rounded up the various awards that precede the Academy Awards, including those from the Directors Guild of America and the Screen Actors Guild; in his calculations, he gave additional weight to those awards with a higher historical success rate, and doubled the score 'for awards whose voting memberships overlap significantly with the academy.' But he isn't the only statistician predicting this year's Oscar winners: David Rothschild, a member of Microsoft's massive research division, has also developed a data-driven model. What does their number-crunching predict? That Argo will win Best Picture, and a bunch of people will win other things."

Slashdot contributor Bennett Haselton writes with "a response to some of the objections raised to my last article, about a design for a distributed social networking protocol, which would allow for decentralized (and censorship-resistant) hosting of social networking accounts, while supporting all of the same features as sites like Facebook." Social networking is no longer new; whether you consider it to have started with online communities in the mid-90s or with the beginnings of sites many people still use today. As its popularity has surged, it has grown in limited ways; modern social networks have made communication between users easier, but they've also made users easier to market to advertisers as well. There's no question that the future of social networking holds more changes that can both help and harm users — perhaps something like what Bennett suggests could serve to mitigate that harm.

eldavojohn writes "As a web developer in the 'Agile' era, I find myself making (or recognizing) more and more important decisions being made in developing for the web. Scalability Rules cemented and codified a lot of things I had suspected or picked up from blogs but failed to give much more thought to and had difficulty defending as a member of a team. A simple example is that I knew state is bad if unneeded but I couldn't quite define why. Scalability Rules provided this confidence as each of the fifty rules is broken down in a chapter that is divided into what, when, how, why and key takeaways. A strength of the book is that these rules cover all aspects of web development; but that became a double edged sword as I struggled through some rules meant for managers or technical operators."

FrederickSeiler writes "When David Harriman, this book's author, was studying physics at Berkeley, he noticed an interesting contrast: 'In my physics lab course, I learned how to determine the atomic structure of crystals by means of x-ray diffraction and how to identify subatomic particles by analyzing bubble-chamber photographs. In my philosophy of science course, on the other hand, I was taught by a world-renowned professor (Paul Feyerabend) that there is no such thing as scientific method and that physicists have no better claim to knowledge than voodoo priests. I knew little about epistemology [the philosophy of knowledge] at the time, but I could not help noticing that it was the physicists, not the voodoo priests, who had made possible the life-promoting technology we enjoy today.' Harriman noticed the enormous gulf between science as it is successfully practiced and science as is it described by post-Kantian philosophers such as Feyerabend, who are totally unable to explain the spectacular achievements of modern science."

theodp writes "Screw that eHarmony Compatibility Matching System nonsense. 'Physical appearance is generally considered one of the most important search criteria among users of online dating services,' according to a patent granted Tuesday to five Microsoft Research Asia inventors. Its Image-Based Face Search technology not only allows people to specify the 'gender, age, ethnicity, location, height, weight, and the like' of their prey, explains Microsoft, it also allows them to 'provide a query image of a face for which they would like to search for similar faces.' So, even though you can't have the real Angelina Jolie or Natalie Portman, Microsoft will fix you up with a look-alike."

Michael J. Ross writes "While it is possible to create a simple website using a base installation of Drupal, the real power of this content management system is achieved through the use of modules, which can be thought of as add-ons that extend the capabilities of Drupal in specific ways — oftentimes in conjunction with other modules. These modules are developed and contributed by PHP programmers who understand how to use one or more of the Drupal application programming interfaces (APIs) to access information stored in a Drupal database, such as content, user profiles, and theme settings. These APIs have changed with Drupal version 7, and thus Drupal coders could benefit from a book that explains how to create Drupal 7 contrib modules." Read on for the rest of Michael's review.

waderoush writes "A startup called Tibion in Sunnyvale, CA, has begun selling battery-powered robotic exoskeletons that help stroke victims with one-sided weakness relearn how to stand, sit, walk, and negotiate stairs. The leg isn't a permanent attachment; the company says patients who use the device for 45 minutes a week for four weeks experience significant gains in walking speed that persist and even improve months after the treatment. They believe that the $40,000 device — which includes sensors that respond to subtle signs of user intentions, such a shift in weight — provides feedback that triggers neuroplasticity, the brain's ability to rewire itself to repair damage."

Ponca City, We Love You writes "The BBC reports that scientists have discovered the 36-million-year-old fossil of a penguin nearly five feet tall and almost twice the weight of an Emperor Penguin, the largest living species. 'The heavier the penguin, the deeper it dives,' says Julia Clarke, a palaeontologist at the University of Texas. 'If that holds true for any penguins, then the dive depths achieved by these giant forms would've been very different.' The bird, named Inkayacu paracasensis, or water king, lived during the late Eocene period and had a long, straight beak, much longer than that of its modern relatives. But, most surprisingly, the giant penguin's feathers were brown and gray, distinct from the black 'tuxedo'" Reader SpuriousLogic notes that it's also getting easier to keep an eye on modern penguins, since Google has extended Street View to Antarctica.

Michael J. Ross writes "In the past, a Web developer tasked with building an online store would most likely do so using a dedicated e-commerce system, instead of a content management system (CMS), because even though the leading CMSs offered more features and flexibility, they did not provide robust e-commerce capabilities, such as product listings, bulk import, pricing in multiple currencies, a built-in shopping cart, and integration with tax and shipping information sources. Since that time, e-commerce systems have become more like CMSs, by adding features such as blogging and forums. At the same time, CMSs are continually expanding their e-commerce potential, usually in the form of developers adding plug-ins. For developers using Drupal, there traditionally have been two major e-commerce plug-ins (known as "modules"): Ubercart and e-Commerce. The former has emerged as the leader, and is explored in Drupal E-commerce with Ubercart 2.x." Read on for the rest of Michael's review.

azoblue writes with a piece in New Scientist that might make you rethink the concept of "statistical certainty." As the article puts it, "even when analysts agree that someone could be a match for a piece of DNA evidence, the statistical weight assigned to that match can vary enormously, even by orders of magnitude." Azoblue writes: "For instance, in one man's trial the DNA evidence statistic ranged from 1/95,000 to 1/13, depending on the different weighing methods used by the defense and the prosecution."

Frequent Slashdot contributor Bennett Haselton's essay this week is about "A Tennessee man is arrested for possessing a picture of Miley Cyrus's face superimposed on a nude woman's body. In a survey that I posted on the Web, a majority of respondents said the man violated the law -- except for respondents who say they were good at math in school, who as a group answered the survey differently from everyone else."

On these pages, admitting that you are a Trekkie is not a mark of shame; it's more like admitting that you are a carbon-based life form, which is true of almost all of us. I watch every movie. I've seen every episode of every series. And as my wife will tell you, I scream "F*** you Rick Berman!' during the credits every time I see it. So when JJ Abrams got a crack at a reboot, I was hopeful. The short review is that I liked it. Keep reading; I'll keep the spoilers down to a minimum. (Continued below.)
