NASA Explains how We Caused the Hottest Decade and are generally screwing ourselves over (Video) The True Superhumans Are Already Among U. We used to think of “superhumans” as comic book heroes possessing extraordinary, even divine-like powers. Now, we are realizing that the true superhumans are already among us – they are the extraordinary Paralympians who are actively embracing technology as a way to transform their “disabilities” into “super-abilities.” To emphasize this point, the promotional video for UK Channel 4's coverage of the 2012 Paralympic Games in London is called “Meet the Superhumans.” This 90-second spot is an inspiring montage of athletic achievement, technological know-how and the power of the human will to overcome anything - whether it is exploding bombs, car accidents or genetic irregularities.
Now more than ever, this brilliant mash-up of sports, science, technology and design is causing a new conception of the postmodern body – a body that is part human, part machine and Harder Than You Think. image: Meet the Superhumans / UK Channel 4. Europe's Newsroom. Moore's Law, the observation by Intel co-founder Gordon E. Moore that the number of transistors on a chip doubles approximately every two years, has been accurate for half a century. As a result, we now carry more processing power in the mobile phones in our pockets than could fit in a house-sized computer in the 1960s.
But by around 2020 Moore's Law will start to reach its limits: the laws of physics will eventually pose a barrier to higher transistor density, but other factors such as heat, energy consumption and cost look set to slow the increase in performance even sooner. At the same time, the world is in the midst of a data explosion, with humans and machines generating, storing, sharing and accessing ever increasing amounts of data in many different forms, on a multitude of different devices that require more energy-efficient, higher-performance processors.
How can computing systems, now facing a post-Moore era, meet this ever growing demand? Useful links: Links to related news: New Wave of Deft Robots Is Changing Global Industry. LHC başlatma ve ilk çarpışmaların 2010 | Şerit Bilim. Après quelques péripéties en 2009 pour le LHC (un incident qui a cassé un morceau de la machine et qui a demandé un an de réparation), le LHC repartait de plus belle à la conquête du Higgs en 2010 en fournissant à la communauté internationale les premières collisions à des énergies encore inégalées. Voici un billet qui avait été publié sur le blog En quête de Sciences lors du redémarrage et un extrait de ce billet de La Science pour Tous lors des premières collisions à hautes énergies qui ont eu lieues le 20 mars 2010. L’heure du week-end n’est pas encore venue pour les employés du CERN. Vendredi en fin d’après-midi, les physiciens ont remis en route le Large hadron collider (LHC), plus grand accélérateur de particules au monde. Pour la première fois depuis son inauguration et ses quelques heures de fonctionnement en septembre 2008, des injections de particules ont eu lieu, l’espace de quelques fractions de seconde, dans les anneaux du LHC.

Werner Heisenberg's uncertainty principle, formulated by the theoretical physicist in 1927, is one of the cornerstones of quantum mechanics. In its most familiar form, it says that it is impossible to measure anything without disturbing it. For instance, any attempt to measure a particle's position must randomly change its speed. The principle has bedeviled quantum physicists for nearly a century, until recently, when researchers at the University of Toronto demonstrated the ability to directly measure the disturbance and confirm that Heisenberg was too pessimistic. "We designed an apparatus to measure a property – the polarization – of a single photon. We then needed to measure how much that apparatus disturbed that photon," says Lee Rozema, a Ph.D. candidate in Professor Aephraim Steinberg's quantum optics research group at U of T, and lead author of a study published this week in Physical Review Letters.

Ingham, via Wikimedia Commons) The computer, smartphone or other electronic device on which you are reading this article has a rudimentary brain—kind of.* It has highly organized electrical circuits that store information and behave in specific, predictable ways, just like the interconnected cells in your brain. On the most fundamental level, electrical circuits and neurons are made of the same stuff—atoms and their constituent elementary particles—but whereas the human brain is conscious, manmade gadgets do not know they exist. Consciousness, most scientists argue, is not a universal property of all matter in the universe. Humans are more than just conscious—they are also self-aware. Numerous neuroimaging studies have suggested that thinking about ourselves, recognizing images of ourselves and reflecting on our thoughts and feelings—that is, different forms self-awareness—all involve the cerebral cortex, the outermost, intricately wrinkled part of the brain.
Emerging Social Media Trends In 2012. In my last blog on Emerging Digital marketing trends this year, I mentioned that trends in Social Media deserve a separate post. It has taken me more than three months to have moved from a draft to an actual blog post, and the only thing that has changed is some of what I originally noted can already be seen in the execution. Let us see what the highlights or current trends are. 1) Social Media will move from acquisition to quality of acquisition- If you pay for a click that helps you acquire a fan, you as a brand will start calculating ROI at some point and will soon realise the value of a fan who might actually be interested versus one who is not.
This article interestingly points out that the generation loves to endorse their likes & dislikes. These are the users who would actually share content, like your updates, your new products & eventually help you go viral. If you are a brand, you’ve probably realised this by now. So what has changed you ask? Arms trade? Drug cartels? Now? Bring it on, Google. Last Friday, I got an email from HuffPost Live, the Huffington Post's new live broadcast platform, asking if I could participate in a panel discussion on Google and its increasing role in things "not search", ranging from tracking the arms trade around the world to its overall dominance in our Internet lives.
The question was, is Google growing in influence faster than our government can keep up and is it stepping into places it shouldn't? More to the point, does Google need regulation and how much are we at risk because of Google's influence? You can check out the discussion here (ironically, conducted via a Google+ Hangout). This panel discussion was particularly in response to Google's recent visualization of the worldwide small arms trade. Along similar lines, Google Executive Chairman, Eric Schmidt, recently noted in a Washington Post op-ed with Jared Cohen (Director of Google Ideas), [The people of Juarez, Mexico] Have been overwhelmed by crime, their lives overcome with fear.

Ray Bradbury FBI File: Sci-Fi Legend Suspected Of Communist Sympathies. Late science-fiction legend Ray Bradbury was actively investigated by the FBI during the 1960s for suspected Communist leanings, according to FBI files released in response to a Freedom of Information Act request by The Huffington Post.
Bradbury aroused the suspicion of the FBI due to his outspoken criticism of the U.S. government and the House Un-American Activities Committee (HUAC), which was investigating real and suspected communists in America. In a full-page ad in Variety, Bradbury had denounced the committee’s probes as “claptrap and nonsense” and several informants in Hollywood also voiced their suspicions about the acclaimed writer to the bureau.
Bradbury’s suspected activity was reported to the bureau by screenwriter Martin Berkeley, who claimed that science fiction writers were prone to being Communists and that the genre was uniquely capable of indoctrinating readers in Communist ideologies.

The corridor of uncertainty. How the first plant came to be. The genome of provides essential clues to the origin of photosynthesis in algae and plants. Science/AAAS Earth is the planet of the plants — and it all can be traced back to one green cell.
The world's lush profusion of photosynthesizers — from towering redwoods to ubiquitous diatoms — owe their existence to a tiny alga eons ago that swallowed a cyanobacteria and turned it into an internal solar power plant. By studying the genetics of a "glaucophyte" — one of a group of just 13 unique microscopic freshwater blue-green algae, sometimes called "living fossils" — an international consortium of scientists led by molecular bioscientist Dana Price of the University of Queensland, Brisbane, has elucidated the evolutionary history of plants. According to the analysis of 's genome of roughly 70 million base pairs, this capture must have occurred only once because most modern plants share the genes that make the merger of photosynthesizer and larger host cell possible.
Plone CMS: Open Source Content Management. Goodnet | Gateway to doing good. Tracking nanotechnology. A team of scientists led by Carnegie's Lin Wang has observed a new form of very hard carbon clusters, which are unusual in their mix of crystalline and disordered structure. The material is capable of indenting diamond. This finding has potential applications for a range of mechanical, electronic, and electrochemical uses. Carbon is the fourth-most-abundant element in the universe and takes on a wide variety of forms—the honeycomb-like graphene, the pencil "lead" graphite, diamond, cylindrically structured nanotubes, and hollow spheres called fullerenes. Some forms of carbon are crystalline, meaning that the structure is organized in repeating atomic units.
Other forms are amorphous, meaning that the structure lacks the long-range order of crystals. At relatively low pressure, the carbon-60's cage structure remained. This material was capable of indenting the diamond anvil used in creating the high-pressure conditions. Results | YazikOpen.
