Computer Scientists Develop New Approach to Sort Cells Up to 38 Times Faster
A team of engineers led by computer scientists at the University of California, San Diego, has developed a new approach that marries computer vision and hardware optimization to sort cells up to 38 times faster than is currently possible. The approach could be used for clinical diagnostics, stem cell characterization and other applications.

Matching eyes to math for translucent images
Matching eyes to math for translucent images
The differences are subtle, but marble, left, scatters light beneath its surface differently than jade, right, in these computer-generated images based on a model of the same statue. Whether it's a rare jade figurine or an ice sculpture, how light passes through a translucent surface is key to its appearance, and humans are sensitive to subtle differences in the result.

Scientists Help Tame Tidal Wave of Genomic Data Using SDSC’s Trestles
Sequencing the DNA of an organism, whether human, plant, or jellyfish, has become a straightforward task, but assembling the information gathered into something coherent remains a massive data challenge. Researchers using computational resources at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego, have created a faster and more effective way to assemble genomic information, while increasing performance.

On the Road to Fault-Tolerant Quantum Computing
On the Road to Fault-Tolerant Quantum Computing
Reliable quantum computing would make it possible to solve certain types of extremely complex technological problems millions of times faster than today's most powerful supercomputers. Other types of problems that quantum computing could tackle would not even be feasible with today's fastest machines.

Detecting program-tampering in the cloud
A new version of 'zero-knowledge proofs' allows cloud customers to verify the proper execution of their software with a single packet of data. For small and midsize organizations, the outsourcing of demanding computational tasks to the cloud - huge banks of computers accessible over the Internet - can be much more cost-effective than buying their own hardware.

Precomputing speeds up cloth imaging
Precomputing speeds up cloth imaging
Creating a computer graphic model of a uniform material like woven cloth or finished wood can be done by modeling a small volume, like one yarn crossing, and repeating it over and over, perhaps with minor modifications for color or brightness. But the final "rendering" step, where the computer creates an image of the model, can require far too much calculating for practical use.

’Zero knowledge’ may answer computer security question
In the age of the Internet, it's getting harder and harder to keep secrets. When you type in your password, there's no telling who might be watching it go by. New research at Cornell may offer a pathway to more secure. The answer is to not send sensitive information at all. Rafael Pass, associate professor of computer science, has developed a new protocol, or set of rules, to create what computer scientists call a "zero knowledge proof." "I think zero knowledge proofs are one of the most amazing notions in computer science," Pass said.

Crowdsourcing creates a database of surfaces
Crowdsourcing creates a database of surfaces
Computer graphics are moving off the movie screen and into everyday life. Home remodeling specialists, for example, may soon be able to to show you how your kitchen would look with marble countertops or stainless steel appliances. To do this, computers have to be able to recognize and simulate common materials; so Cornell researchers have drawn on uniquely human skills to build a database of surfaces computers can work with.

More Realistic Simulated Cloth for More Realistic Video Games and Movies
Computer scientists develop new model to simulate cloth on a computer with unprecedented accuracy Computer scientists at the University of California, San Diego, have developed a new model to simulate with unprecedented accuracy on the computer the way cloth and light interact. The new model can be used in animated movies and in video games to make cloth look more realistic.

Making connections in the eye
Wiring diagram of retinal neurons is first step toward mapping the human brain. The human brain has 100 billion neurons, connected to each other in networks that allow us to interpret the world around us, plan for the future, and control our actions and movements. MIT neuroscientist Sebastian Seung wants to map those networks, creating a wiring diagram of the brain that could help scientists learn how we each become our unique selves.

Research points toward better colonoscopy
New technology offers three-dimensional images, making it easier to detect precancerous lesions. MIT researchers have developed a new endoscopy technology that could make it easier for doctors to detect precancerous lesions in the colon. Early detection of such lesions has been shown to reduce death rates from colorectal cancer, which kills about 50,000 people per year in the United States.

Birds and humans have similar brain wiring
Birds and humans have similar brain wiring
We may have more in common with pigeons than previously thought, according to research showing both animals' brains are wired in a similar way. A researcher from Imperial College London and his colleagues have developed for the first time a map of a typical bird brain, showing how different regions are connected together to process information.

Robot mom would beat robot butler in popularity contest
UNIVERSITY PARK, Pa - If you tickle a robot, it may not laugh, but you may still consider it humanlike - depending on its role in your life, reports an international group of researchers. Designers and engineers assign robots specific roles, such as servant, caregiver, assistant or playmate. Researchers found that people expressed more positive feelings toward a robot that would take care of them than toward a robot that needed care.

Timing of tweets is clue to authenticity of tweeters
Timing of tweets is clue to authenticity of tweeters
Scientists determine the difference between human tweeters, those managed by groups of people and automated Twitter accounts based on tweet timings. The researchers, from Imperial College London, found that they could easily tell if humans were responsible for tweets, irrespective of their content, based on when the user's tweet was posted.

Development of New Advanced Materials to Get Boost
The Materials Project-an open-access Google-like database for materials research developed by Lawrence Berkeley National Laboratory (Berkeley Lab) and the Massachusetts Institute of Technology (MIT)-is working with Intermolecular, Inc. to enhance the tool's modeling capabilities and thus accelerate the speed of new material development by tenfold or more over conventional approaches.

Almost Half of Mobile Apps Access Privacy-sensitive Data on iOS devices, Computer Scientists Find
Almost half of the mobile apps running on Apple's iOS operating system access the unique identifier of the devices where they're downloaded, computer scientists at the University of California, San Diego, have found. In addition, more than 13 percent access the devices' location and more than 6 percent the address book.

What makes people click?
A new study has analysed tens of thousands of articles available to readers of online news and created a model to find out 'what makes people click'. The researchers developed a model of "news appeal" based on the words contained in an article's title and text intro, which is what a reader uses when they choose to click on a story.

Interactive public displays not being used to full potential, says research
Interactive public information displays and wallflowers have something in common, according to University of Sydney information technologies researchers: they simply sit around hoping someone will notice them. The need for Interactive Public Information Displays (PIDs) to overcome a number of challenges will be reported this week at the International Symposium on Pervasive Displays in Mountain View, California.
