• The Computer That Stores and Processes Information At the Same Time →

  

  The human brain is an extraordinary computing machine. Nobody understands exactly how it works its magic but part of the trick is the ability to store and process information at the same time.

  That’s entirely unlike conventional computers which store information in random access memory or on hard disc and shuttle it back and forth as required to a central processing unit.

  The time and energy all this takes is the thing that ultimately limits conventional computing performance, the so-called von Neumann bottleneck. Essentially, it is this that prevents conventional computers from approaching the performance of biological ones.

• What's Lost (And Found) In Machine Translation →

  A few milestones in the short but storied history of machine translation: in 1939, Bell Labs presented the first speech synethesizing device, the Voder, at the World’s Fair in New York. In 1978, the first spoken words were transmitted across the Internet. June 2012 saw the release of VoiceTra4U-M, an iPhone app developed by the global Universal Speech Translation Advanced Research Consortium (U-STAR) which enables voice translation of 13 different languages.

• Quantum Dots Give Notebooks a New Glow →

  

  A layer of nanomaterial that gives a liquid-crystal display the rich range of colors usually possible only with more expensive technologies will be commercialized later this year by the materials giant 3M and Nanosys, a private company in Palo Alto, California. Nanosys representatives say they are in talks with major display manufacturers to adopt the quantum-dot films, and that they will be in a 15.6-inch notebook computer available next year.

• Quantum computers are still years away, but a trio of theorists has already figured out at least one talent they may have. According to the theorists, including one from the National Institute of Standards and Technology (NIST), physicists might one day use quantum computers to study the inner workings of the universe in ways that are far beyond the reach of even the most powerful conventional supercomputers.

  Quantum computers require technology that may not be perfected for decades, but they hold great promise for solving complex problems. The switches in their processors will take advantage of quantum mechanics – the laws that govern the interaction of subatomic particles. These laws allow quantum switches to exist in both on and off states simultaneously, so they will be able to consider all possible solutions to a problem at once.

• New DNA Computer Stores 1 Bit of Data →

  

  Bioengineers at Stanford University have turned living cells into data storage devices that can store a rewriteable small amount data, just like silicon devices. Sections of DNA in the researchers’ engineered cells can sit in one of two positions, representing the 0s and 1s of digital data. “Essentially, if the DNA section points in one direction, it’s a zero. If it points the other way, it’s a one,” Pakpoom Subsoontorn, one of the researchers in the study, said in a statement. Biological bits might help future scientists count cancer cells as they divide or study other life processes. For now, however, it’s accomplishment enough just to get biological stuff to hold and rewrite digital data, said Drew Endy, senior scientist in the project.

• Google Gets Transparent with Glass, Its Augmented Reality Project →

  

  Larry Page and Sergey Brin have long had the dream of a hands-free, mobile Google, where search was a seamless process as you moved around the world. As the years progressed the vision did, too, expanding beyond search to persistent connections with the people in your lives.

  In other words, Google’s view of the world now has the social side fully baked into it.

• Eye-tracking computer programs and privacy. →

  

  Consider, for a moment, the following list: Republican. Abortion. Democrat. Future. Afghanistan. Health care. Same-sex marriage.

  There is an enormous amount of information reflected in the way you just read that list. Did your eyes pause for a fraction of a second on certain words? Did your pupils dilate, ever so slightly, at any point while you were reading the list? For some words did your eyes blink at a different rate? Did you backtrack to reread any words, and if so, which ones, when, and for how long?

• New computers respond to students' emotions, boredom →

  

  Emotion-sensing computer software that models and responds to students’ cognitive and emotional states — including frustration and boredom — has been developed by University of Notre Dame Assistant Professor of Psychology Sidney D’Mello, Art Graesser from the University of Memphis and a colleague from Massachusetts Institute of Technology. D’Mello also is a concurrent assistant professor of computer science and engineering.

• Schizophrenia patients' ability to monitor reality may be helped by computerized training →

  People with schizophrenia who completed 80 hours of intensive, computerized cognitive training exercises were better able to perform complex tasks that required them to distinguish their internal thoughts from reality.

  As described in the journal Neuron (2/22/12), a small clinical study conducted at the San Francisco VA Medical Center (SFVAMC) and the University of California, San Francisco (UCSF), tested the digital exercises as a new therapy for schizophrenia.

• Genetically-inspired algorithm could improve network security →

  

  Computer scientists at Wake Forest University are using a genetically-inspired algorithm that proactively discovers more secure computer network configurations.

  Inadequate security configurations are responsible for a large number of security vulnerabilities — up to 80 percent of those identified by the United States Air Force, for example. Computer science associate professor Errin Fulp and graduate student Michael Crouse were funded by a grant from Pacific Northwest National Laboratory to improve defence mechanisms with minimal human interaction.

• Phase-change materials can fix machine memory crunch →

  

  WE WALK about with thousands of songs, photos and videos in our pockets, but we won’t be able to keep cramming more and more onto our memory cards forever. While last week’s news that a single bit of digital information has been stored on just 12 atoms was remarkable, at some point we are going to reach a limit. What happens when we can store a single bit on an atom, for example?

  Now a radical approach could solve our impending memory crisis and allow a massive increase in storage density - without making chips any bigger. It may also force us to reassess the notion that all things digital must be made up of 1s and 0s.

• World's Largest Quantum Computation Uses 84 Qubits →

  

  Quantum computers are in danger of losing their lustre. These machines exploit the strange rules of quantum mechanics to carry out calculations that are vastly more powerful than anything that conventional computers can do.

  Or so we’re told. Quantum computers in one form or another have been carrying out calculations for more than a decade. But far from putting conventional computers to shame, these devices have yet to outperform the calculating abilities of a primary school child.

• Wearing Your Computer on Your Sleeve →

  

  Technology often has a way of fixing the problems it creates. Here’s one that needs solving.

  The invention of the smartphone has created a world where millions of people stroll through life constantly staring into a mobile device, like Narcissus at the edge of a pond.

  I know. I’m one of them.

  People are not going to put these devices down in the near future. Realistically, we will become only more absorbed by the Screen. Technology will have to solve this problem. It will do so by creating wearable computers.
