A real-world demonstration of a thought experiment conducted at the University of Vienna, has produced a result that is somewhat befuddling to people with what the lead researcher calls a "naïve classical world view." Two pairs of particles are either quantum-entangled or not. One person makes the decision as to whether to entangle them or not, and another pair of people measure the particles to see whether they're entangled or not.

Mathematicians have now visualized abstract mathematical objects called flat tori - items resembling donuts with corrugated, fractal surfaces. These were thought to be impossible to envision in ordinary 3-D space... until now.

n 1983, a Chinese fast-food restaurant in Pasadena, California hired a curious-looking pair of servers: two robots named Tanbo R-1 and Tanbo R-2. At 4.5 feet tall and 180 pounds, the robots would scoot around; bringing trays of chow mein, spareribs and fortune cookies to customers' tables.

Scaling College Composition by AUDREY WATTERS on 22 APR, 2012 I've been thinking a lot this week about two seemingly unrelated news items. The first, the research by David Shermis and Ben Hamner that found that automated essay grading software performs comparably to human graders. (See the Inside Higher Ed story.) The second, the official unveiling of Coursera, the latest online learning startup to spin out of Stanford, that promises to offer a full course catalog, including many classes in the humanities. (Here's my write-up of the news). The connection: scaling how we assess student writing.

In our most recent Scientific Reports paper, we show how the visual pattern recognition ability of humans combined with the high processing speed of computers leads to a visual analytics method for discovering groups of nodes characterized by common network properties.

People sometimes worry about the Singularity [Vinge, 1993; Kurzweil, 2005], or about the world being taken over by artificially intelligent robots. I believe the risks of these are very small. However, few people recognize that we already share our world with artificial creatures that participate as intelligent agents in our society: corporations. Our planet is inhabited by two distinct kinds of intelligent beings --- individual humans and corporate entities --- whose natures and interests are intimately linked. To co-exist well, we need to find ways to define the rights and responsibilities of both individual humans and corporate entities, and to find ways to ensure that corporate entities behave as responsible members of society.

Note-I am going to try this for our blog. If you've ever wondered how some website that looks like it was an early draft from the proverbial infinite number of monkeys on infinite keyboards managed to get to the top of a search result page instead of something you actually want to read (or something you've written), you've been victimized by the dark art of search engine optimization (SEO). In the never-ending battle for the top of the Google search results page, and for advertising click-throughs, marketers and bloggers enlist an ever-changing bag of tricks to game search engine algorithms, often with the help of SEO consultants and a collection of tools that track the best tactics of the moment.

Allison sez, "Michael Geist provides some commentary on yesterday's announcement by Association of Universities and Colleges of Canada and Access Copyright. His conclusion: 'For those that sign the model license, the new AUCC - Access Copyright deal is simply more of the same: AUCC and its institutions pass along copyright costs to students, Access Copyright gets millions in revenues despite ongoing questions about its repertoire (with thousands used to lobby against education copyright reforms and most of the money going to foreign collectives and publishers, not authors), and the potential for digitally-oriented changes within Canadian higher education heading back to the back burner.'"

Scientists are pioneering the use of 3D printers to create drugs and other chemicals at the University of Glasgow. Researchers have used a £1,250 system to create a range of organic compounds and inorganic clusters - some of which are used to create cancer treatments. Longer term, the scientists say the process could be used to make customised medicines.

On Tuesday, a new company called Planetary Resources will announce its existence at the Charles Simonyi Space Gallery at The Museum of Flight in Seattle. It's not clear what the firm does, but its roster of backers incudes Google cofounders Larry Page and Eric Schmidt, filmmaker James Cameron, former Microsoftie (and space philanthropist) Charles Simonyi, and Ross frikkin' Perot.

Ghost Invaders is a mystery game immersive and hybrid (between ARG, JDR and NG) happens on the Internet and in the town of Saint-Denis. As the game progresses, you will find many events: concerts, installations ghosts, treasure hunts, street actors ...

In the fall of 2010, Dr. Ferric C. Fang made an unsettling discovery. Dr. Fang, who is editor in chief of the journal Infection and Immunity, found that one of his authors had doctored several papers

n 1961, IBM commissioned Charles and Ray Eames to create an exhibition for the California Museum of Science and Industry.  The resulting exhibition, called Mathematica: a World of Numbers, is a founding document of interactive STEM (Science Technology Engineering and Math) exhibitions.

SANTA BARBARA-"Maybe we're just too dumb," Nobel laureate physicist David Gross mused in a lecture at Caltech two weeks ago. When someone of his level wonders whether the unification of physics will always be beyond mortal minds, it gets you worried. Since his lecture, I've been learning about a theory that seems to confirm Gross's worry. It is so ridiculously hard that it could be the subject of an Onion parody. But at the same time, I've been watching how physicists are trying to power through their intimidation, because the theory promises a new way of understanding what space and time really are, at a deep level.

Google's swooshy new concept video for augmented reality goggles (or "spex", if you will) has certainly put the virtual cat among the digital pigeons. An attempt, perhaps, to leapfrog the iPad - if Google can persuade us that what we really want is headwear that will let us see things that aren't really there.

IT professionals will increasingly act as data managers as the role of application manager becomes superfluous, according to a report called Technology Vision 2011, from IT services firm Accenture. In addition, the coming years will see IT decision-makers choosing platforms that are best able to manage soaring volumes of data as opposed to platforms designed to support applications.

This honor goes to Dr. Ronald Breslow of Columbia University, who ended his recent paper "Evidence for the Likely Origin of Homochirality in Amino Acids, Sugars, and Nucleosides on Prebiotic Earth" in the Journal of the American Chemical Society with an ominous editorial. After an otherwise technical paper about the prehistoric origins of amino acids, the conclusion takes a turn for the extremely sinister. Emphasis is ours:

A massive new storyline will creepy-crawl across every aspect of the Dungeons & Dragons landscape this year, as the Demon Queen of Spiders and her drow minions rise from their underground domains to take on the surface world. Rise of the Underdark will impact D&D RPG books, organized play, novels, a new miniatures game and even D&D Online, the free-to-play MMORPG. Hope you like drow (or enjoy killing them).

At least since the followers of Ned Ludd smashed mechanized looms in 1811, workers have worried about automation destroying jobs. Economists have reassured them that new jobs would be created even as old ones were eliminated. For over 200 years, the economists were right. Despite massive automation of millions of jobs, more Americans had jobs at the end of each decade up through the end of the 20th century. However, this empirical fact conceals a dirty secret. There is no economic law that says that everyone, or even most people, automatically benefit from technological progress.

As a child I used to read my grandfather's Popular Science and Popular Mechanics magazines. The constant promise and inevitable disappointment of amazing technologies that mostly never materialized (a problem likely exacerbated by my focus on the amazing and outlandish ones) made me skeptical of futurist predictions. It is somewhat strange then, that I now commonly find myself a proponent of futurist visions equally as grand as those that once made me a cynic. But I'm not alone in seeing the near future as a quickly changing technological landscape. In their recent book Race Against The Machine: How the Digital Revolution is Accelerating Innovation, Driving Productivity, and Irreversibly Transforming Employment and the Economy, MIT's Erik Brynjolfsson and Andrew McAfee* offer a similarly sweeping view of how technology is, and will be, shaping our future
