An anonymous reader writes "The fear of flying or of skittering spiders can mean more than just a momentary increase in heart rate and a pair of sweaty palms. A hard-core phobia can lead to crippling anxiety. Now an international team of researchers says it believes it has found a way to silence the gene that feeds phobic fear via a novel mechanism of gene regulation associated with fear extinction. The notion appears to be that phobias arise from experiences that have left an outsized imprint on gene expression, and that undoing this can undo the anxiety itself. The study was published this month (abstract) in the Proceedings of the National Academy of Sciences."

KentuckyFC (1144503) writes "Last year, astronomers announced that a small ball of ice and rock heading towards the inner Solar System could turn out to be the most eye-catching comet in living memory. They calculated that Comet Ison's orbit would take it behind the Sun but that it would then head towards Earth where it would put on a spectacular display of heavenly fireworks. Sure enough, Ison brightened dramatically as it headed Sunwards. But as astronomers watched on the evening of 28 November, the brightly flaring Ison moved behind the Sun but never emerged. The comet simply disappeared. Now a new analysis of the death of Ison suggests that the comet was doomed long before it reached the Sun. Images from several Sun-observing spacecraft that had a unique view of events, indicate that Ison exhausted its supply of water and other ice in the final flare-ups as it approached the Sun. The new study shows that all that was left in its last hours were a few hundred thousands pebbles glowing brightly as they vaporized in the Sun's heat. In fact, Comet Ison died in full view of the watching hordes of astronomers on Earth who did not realize what they were watching at the time."

ckwu (2886397) writes "Two independent research groups report the first transistors built entirely of two-dimensional electronic materials, making the devices some of the thinnest yet. The transistors, just a few atoms thick and hence transparent, are smaller than their silicon-based counterparts, which would allow for a super-high density of pixels in flexible, next-generation displays. The research teams, one at Argonne National Laboratory and the other at the University of California, Berkeley, used materials such as tungsten diselenide, graphene, and boron nitride to make all three components of a transistor: a semiconductor, a set of electrodes, and an insulating layer. Electrons travel in the devices 70 to 100 times faster than in amorphous silicon. Such a high electron mobility means the transistors switch faster, which dictates a display's refresh rate and is necessary for high-quality video, especially 3-D video."

This policy follows the pattern set by China, Pakistan, Turkey, and Iran." Any site with more than 3000 daily visitors will be required to register and be held to a number of restrictions, quoting the article: "Besides registering, bloggers can no longer remain anonymous online, and organizations that provide platforms for their work such as search engines, social networks and other forums must maintain computer records on Russian soil of everything posted over the previous six months."

theodp (442580) writes "Meet your new 'Room Mom', kids! On Tuesday, Google announced a preview of Classroom, a new, free tool in the Google Apps for Education suite. From the announcement: 'With Classroom, you'll be able to: [1] Create and collect assignments: Classroom weaves together Google Docs, Drive and Gmail to help teachers create and collect assignments paperlessly. They can quickly see who has or hasn't completed the work, and provide direct, real-time feedback to individual students. [2] Improve class communications: Teachers can make announcements, ask questions and comment with students in real time—improving communication inside and outside of class. [3] Stay organized: Classroom automatically creates Drive folders for each assignment and for each student. Students can easily see what's due on their Assignments page.'

Addressing privacy concerns, Google reassures teachers, 'We know that protecting your students' privacy is critical. Like the rest of our Apps for Education services, Classroom contains no ads, never uses your content or student data for advertising purposes, and is free for schools.' After the recent torpedoing of Bill Gates' $100M inBloom initiative, Google might want to have a privacy pitch ready for parents, too!"

First time accepted submitter aojensen (1503269) writes "GitHub has made good on promises to open source Atom, a programmer's text editor based on Chromium. Atom is released under the MIT license (source repository). GitHub announced the following on their blog: 'Because we spend most of our day in a text editor, the single most important feature we wanted in an editor was extensibility. Atom is built with the same open source technologies used by modern web browsers. ... But more importantly, extending Atom is as simple as writing JavaScript and CSS, two languages used by millions of developers each day.'

Apart from being extensible via HTML, JavaScript, and CSS, Atom also offers out-of-the-box Node.js integration, a modular design with a built-in package manager (apm), and extensive features such as file system browser, themes, project-wide search and replace, panes, snippets, code folding, and more. Launched only 10 weeks ago, Atom seems to have a well-established ecosystem of packages and extensions already." The editor is based on atom-shell, a more general framework for building desktop apps using JavaScript/HTML. Beware: according to the FAQ, by default it sends "usage data" to Google Analytics (which can be disabled at least).

RightsCorp says Europe needs its help in fighting piracy." They recently expanded operations into Canada as well.

MarkWhittington writes: "The drive by SpaceX to make the first stage of its Falcon 9 launch vehicle reusable has attracted the attention of both the media and the commercial space world. It recently tested a first stage which 'soft landed' successfully in the Atlantic Ocean. However both NASA and the French space agency CNES have cast doubt that this kind of reusability could ever be made practical, according to a Monday story in Aviation Week. SpaceX is basing its plan on the idea that its Merlin 1D engines could be reused 40 times. However, citing their own experience in trying to reuse engines, both NASA and the CNES have suggested that the technical challenges and the economics work against SpaceX being able to reuse all or part of their rockets. NASA found that it was not worth trying to reuse the space shuttle main engines after every flight without extensive refurbishment. The CNES studied reusing its Ariane 5 solid rocket boosters liquid fueled and reusable but soon scrapped the idea."

An anonymous reader writes "Patrick Lin of California Polytechnic State University explores one of the ethical problems autonomous car developers are going to have to solve: crash prioritization. He posits this scenario: suppose an autonomous car determines a crash is unavoidable, but has the option of swerving right into a small car with few safety features or swerving left into a heavier car that's more structurally sound. Do the people programming the car have it intentionally crash into the vehicle less likely to crumple? It might make more sense, and lead to fewer fatalities — but it sure wouldn't feel that way to the people in the car that got hit. He says, '[W]hile human drivers may be forgiven for making a poor split-second reaction – for instance, crashing into a Pinto that's prone to explode, instead of a more stable object – robot cars won't enjoy that freedom. Programmers have all the time in the world to get it right. It's the difference between premeditated murder and involuntary manslaughter.' We could somewhat randomize outcomes, but that would lead to generate just as much trouble. Lin adds, 'The larger challenge, though, isn't thinking through ethical dilemmas. It's also about setting accurate expectations with users and the general public who might find themselves surprised in bad ways by autonomous cars. Whatever answer to an ethical dilemma the car industry might lean towards will not be satisfying to everyone.'"

Nerval's Lobster writes: "Dice [note: our corporate overlord] collects a ton of data from job postings. Its latest findings? The number of jobs posted for NoSQL experts has risen 54 percent year-over-year, ahead of postings for professionals skilled in so-called 'Big Data' (up 46 percent), Apache Hadoop (43 percent), and Python (16 percent). Employers are also seeking those with expertise in Software-as-a-Service platforms, to the tune of 20 percent more job postings over the past twelve months; in a similar vein, postings for tech professionals with some cloud experience have leapt 27 percent in the same period. Nothing earth-shattering here, but it's perhaps interesting to note that, for all the hype surrounding some of these things, there's actually significant demand behind them."
