Levar Burton Enlists the Internet To Help Resurrect Reading Rainbow
An anonymous reader writes “A former MIT instructor and students have come up with software that can write an entire essay in less than one second; just feed it up to three keywords.The essays, though grammatically correct and structurally sound, have no coherent meaning and have proved to be graded highly by automated essay-grading software. From The Chronicle of Higher Education article: ‘Critics of automated essay scoring are a small but lively band, and Mr. Perelman is perhaps the most theatrical. He has claimed to be able to guess, from across a room, the scores awarded to SAT essays, judging solely on the basis of length. (It’s a skill he happily demonstrated to a New York Times reporter in 2005.) In presentations, he likes to show how the Gettysburg Address would have scored poorly on the SAT writing test. (That test is graded by human readers, but Mr. Perelman says the rubric is so rigid, and time so short, that they may as well be robots.).'” Read more of this story at Slashdot.

Hugh Pickens DOT Com (2995471) writes “Michael S. Rosenwald reports in the Washington Post that, according to cognitive neuroscientists, humans seem to be developing digital brains with new circuits for skimming through the torrent of information online at the expense of traditional deep reading circuitry… Maryanne Wolf, one of the world’s foremost experts on the study of reading, was startled last year to discover her brain was apparently adapting, too. After a day of scrolling through the Web and hundreds of e-mails, she sat down one evening to read Hermann Hesse’s challenging novel The Glass Bead Game. ‘I’m not kidding: I couldn’t do it, ‘ says Wolf. ‘It was torture getting through the first page. I couldn’t force myself to slow down so that I wasn’t skimming, picking out key words, organizing my eye movements to generate the most information at the highest speed. I was so disgusted with myself.’ The brain was not designed for reading and there are no genes for reading like there are for language or vision. … Before the Internet, the brain read mostly in linear ways — one page led to the next page, and so on. The Internet is different. With so much information, hyperlinked text, videos alongside words and interactivity everywhere, our brains form shortcuts to deal with it all — scanning, searching for key words, scrolling up and down quickly. This is nonlinear reading, and it has been documented in academic studies. … Some researchers believe that for many people, this style of reading is beginning to invade our ability to deal with other mediums. ‘We’re spending so much time touching, pushing, linking, scrolling and jumping through text that when we sit down with a novel, your daily habits of jumping, clicking, linking is just ingrained in you, ‘ says Andrew Dillon.” Read more of this story at Slashdot.

Online Skim Reading Is Taking Over the Human Brain
Graphene + Copper (not to scale, obviously) About a year ago, I traveled to Cornell University to interview a bunch of materials scientists who work at the nanoscale level. This means they work with stuff that is very, very tiny. A nanometer is a billionth of a meter. One of the challenges nearly all of the scientists kept mentioning is the issue of overheating in electronics. Most of us are directly familiar with the heat released from our computers when we balance them on our lap for a period of time, for example. And this becomes a big deal as devices get smaller and smaller. The smaller the copper wires—which connect chips, among other things—the more heat they emit. This is important for future devices and wearables. Scientists are exploring all kinds of solutions but a proven one has recently been announced in the journal Nano Letters. We’ve mentioned the magic material graphene before and it continues to be the superhero material, coming to the rescue over and over again. This time, it shows up as a possible damper for heated copper wires. Graphene is a one-atom thick material that can move electrons and heat. And it is able to cling to copper. Apparently by sandwiching copper between layers of graphene, the heat created by the metal is decreased by 25 percent. When attached to copper, the graphene actually changes its structure in such a way that allows the heat to move more freely through the metal, instead of being trapped in it.

Born around 276 B.C. in Cyrene, Libya, Eratosthenes soon became one of the most famous mathematicians of his time. He is best known for making the first recorded measurement of the Earth’s circumference, which was also remarkably accurate. (And, yes, people at that point had known for some time that the world wasn’t flat, contrary to popular belief .) Read more…

First time accepted submitter ultranova writes with news of a new phase in trials for an HIV vaccine. From the article: “Some 1, 000 patients throughout France and Switzerland will take part on the trials, with the first phase involving hundreds of HIV sufferers. Participant numbers will increase as the program progresses. … According to Reijonen, the GTU technology developed by FIT Biotech is also suitable for use as a preventive HIV vaccine, however, he says that such a drug is still ten years away.The central idea behind HIV vaccine development is the use of genetic immunization. Genes are introduced into the body in order to generate a controlled immune response against HIV. Gene Transport Unit (or GTU) technology refers to FIT Biotech’s patented method by which genes can be safely introduced into the body.” Read more of this story at Slashdot.

Nate the greatest writes “Intel didn’t mention how much they paid for digital textbook startup Kno when they announced the acquisition last week but inside sources are now saying that the digital textbook startup was picked up for a song. GigaOm reported earlier today that their sources told them that Kno sold effectively for pennies on the dollar: ‘Well placed sources who were in the know told us that the company sold for $15 million with some retention bonuses for the employees. Intel bought the company mostly for its hardware-related intellectual property and the employees. Intel also was one of the largest investors in the company — having pumped in $20 million via its Intel Capital arm.’ Kno had raised $73 million in venture capital since it was founded 4 years ago, and it picked up another $20 million in debt. This deal was nothing less than a fire sale, and that does not bode well for the digital textbook market or other startups in this niche. Inkling, for example, just raised $20 million dollars this summer in order to compete in a market that where one of their competitors failed.” Read more of this story at Slashdot.

Digital Textbook Startup Kno Was Sold For $15 Million
Nerval’s Lobster writes “While Google built its highly profitable search business atop a complex mix of algorithms and machine learning, its latest initiative actually depends on people power: Helpouts, which allows users (for a fee) to video-chat with experts in particular fields. Google has rolled out the service with a few brands in place, such as One Medical and Weight Watchers, and promises that it will expand its portfolio of helpful brands and individuals over the next several months. Existing categories include Cooking, Art & Music, Computers & Electronics, Education & Careers, Fashion & Beauty, Fitness & Nutrition, Health, and Home & Garden. Some Helpouts charge nothing for their time; for example, the ‘Cooking’ section of the Website already features a handful of chefs willing to talk users through baking, broiling, slicing and dicing for free. A few vendors in the Computers & Electronics section, by contrast, charge $2 per minute or even $200 per Hangout session for advice on WordPress setup, Website design, and more. So why is Google doing this? There are plenty of Websites that already dispense advice, although most rely on the written word—Quora, for example, lets its users pose text-based questions and receive answers. There’s also rising interest in Massive Open Online Courses, also known as MOOCs, in which thousands of people can sign online to learn about something new. In theory, Helpouts (if it’s built out enough) could make Google a player in those markets, as well as specialized verticals such as language learning — and earn some healthy revenue in the process.” Read more of this story at Slashdot.

Google Relying On People Power For ‘Helpouts’
Hugh Pickens DOT Com writes “Los Angeles Unified School District started issuing iPads to its students this school year, as part of a $30 million deal with Apple. Now Sam Sanders reports at NPR that less than a week after getting their iPads, high school students have found a way to bypass software blocks on the devices that limit what websites the students can use. The students are getting around software that lets school district officials know where the iPads are, what the students are doing with them at all times and lets the district block certain sites, such as social media favorites like Facebook. ‘They were bound to fail, ‘ says Renee Hobbs, who’s been a skeptic of the iPad program from the start. ‘There is a huge history in American education of being attracted to the new, shiny, hugely promising bauble and then watching the idea fizzle because teachers weren’t properly trained to use it and it just ended up in the closet.’ The rollout of the iPads might have to be delayed as officials reassess access policies. Right now, the program is still in Phase 1, with fewer than 15, 000 iPads distributed. ‘I’m guessing this is just a sample of what will likely occur on other campuses once this hits Twitter, YouTube or other social media sites explaining to our students how to breach or compromise the security of these devices, ‘ says Steven Zipperman. ‘I want to prevent a “runaway train” scenario when we may have the ability to put a hold on the roll-out.’ The incident has prompted questions about overall preparations for the $1-billion tablet initiative.” Read more of this story at Slashdot.
