Researchers from North Carolina State University have developed a new software tool to prevent performance disruptions in cloud computing systems by automatically identifying and responding to potential anomalies before they can develop into problems.
Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1s and 0s were represented by bursts of light, instead of electricity. Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires.
Scientists from the University of Aberdeen's Marine Biodiscovery Center and the University of St Andrews presented their work on the components of a new type of computer chip created using molecules from a sea squirt sourced from the bottom of the Great Barrier Reef.
In Finland, researchers have experimentally determined the conditions for rebounding of water droplets moving on superhydrophobic surfaces. Like billiard balls, these droplets move by way of collisions, allowing the scientists to build “droplet logic”. When combined with chemical reactions these devices demonstrate elementary Boolean logic operations.
Particular sequences of the familiar double helix structure of DNA form genes, which tell cells how to make proteins. But the vast majority of DNA lies outside of genes and is poorly understood. A massive project by more than 500 scientists to gain a comprehensive look at how our DNA works has produced an encyclopedia of information that reveals extraordinarily complex networks that tell our genes what to do. It also reveals just how much of the human genome is active.
A refined method developed at NIST for measuring nanometer-sized objects may help computer manufacturers more effectively size up the myriad tiny switches packed onto chips' surfaces. The method, which makes use of multiple measuring instruments and statistical techniques, is already drawing attention from industry.
Only about 1% of the human genome contains gene regions that code for proteins, raising the question of what the rest of the DNA is doing. Scientists have now begun to discover the answer: About 80% of the genome is biochemically active, and likely involved in regulating the expression of nearby genes, according to a study from a large international team of researchers.
Over the past few decades, the hunt for extrasolar planets has yielded incredible discoveries. Now, planetary researchers have a new tool—simulated models of how planets are born. A team of researchers at The University of Texas at Austin are using supercomputers to model and simulate the protostellar disks that precede the formation of planet.
Disorders such as schizophrenia can originate in certain regions of the brain and then spread out to affect connected areas. Identifying these regions of the brain, and how they affect the other areas they communicate with, would allow drug companies to develop better treatments and could ultimately help doctors make a diagnosis. But interpreting the vast amount of data produced by brain scans to identify these connecting regions has so far proved impossible, until now.
An international research collaboration led by scientists in the U.K. has developed a new approach to quantum computing that could lead more widespread use of new quantum technologies. The breakthrough has been a move from glass-based circuitry that allowed circuits to manipulate photons to a silicon-based technology that accomplishes the same calculations using quantum mechanical effects.
Most major Websites maintain huge databases. Almost any transaction on a shopping site, travel site, or social networking site require multiple database queries, which can slow response time. Now, researchers at Massachusetts Institute of Technology have developed a system that automatically streamlines Websites' database access patterns, making the sites up to three times as fast.
Researchers from the Australian National University have taken a quantum leap towards developing the next generation of super-fast networks needed to drive future computers. The team has developed a technique that allows for quantum information to travel at higher bandwidth using a beam of light and the phenomenon called entanglement.
On Tuesday IBM introduced a new line of mainframe computers the company calls its most powerful and technologically advanced ever. The zEnterprise EC12 mainframe server is designed to help users securely and quickly sift through massive amounts of data. Running at 5.5 GHz, IBM said the microprocessor that powers the mainframe is the fastest chip in the world.
A critical element in any microchip is an inverter—an electronic component that spits out zeros when it is given ones, and vice versa. Complementary metal-oxide-semiconductor, or CMOS, is the industry standard for this type of component, but still requires billions of dollars to achieve production scale. Researchers have recently pioneered a room-temperature additive process that creates a nanoscale inverter quickly and at low cost.
Cancer metastasis, the escape and spread of primary tumor cells, is a common cause of cancer-related deaths. But metastasis remains poorly understood, and only recently have studies indicate that blood’s “stickiness” actually tears off tumor cells. Using a statistical technique employed by animators, scientists created a new computer simulation that reveals how cancer cells enter the bloodstream and the physical forces involved.
At outdoor athletic competitions?at the Olympic Games, for example?athletes pushed themselves to the limit. But it’s hard to depict this in pictures alone. Researchers at the Fraunhofer Institute in Germany have created an intelligent camera that instantly delivers more complete picture of the action, supplying additional metadata acceleration, temperature, or heart rate.
Researchers at the Stanford University School of Medicine and Intel Corp. have collaborated to synthesize and study a grid-like array of short pieces of a disease-associated protein on silicon chips normally used in computer microprocessors. Used recently to identify patients with a severe form of lupus, the new technology has the potential to improve diagnoses of a multitude of diseases.
A research team at the University of Santa Barbara has designed and fabricated a quantum processor capable of factoring a composite number—in this case the number 15—into its constituent prime factors, 3 and 5. Although modest compared to, say, a 600-digit number, the algorithm they developed was right about half the time, matching theoretical predictions and marking a milestone on the trail of building a stronger quantum computer.
Using next-generation sequencing technology and a new strategy to encode 1,000 times the largest data size previously achieved in DNA, Harvard University geneticist George Church has encoded his book in life's language. While the volume of data is comparatively modest, the density of 5.5 petabits, or 1 million gigabits per cubic meter, is off the charts.
IBM announced it has entered into a definitive agreement to acquire Texas Memory Systems (TMS), a developer of high-performance flash memory solutions. Following acquisition close, IBM plans to invest in and support the TMS product portfolio, and will look to integrate over time TMS technologies into a variety of solutions including storage, servers, software, and PureSystems offerings.
In order to preserve the integrity of data in a quantum computer, the quantum mechanical system must be stable and shielded. But the information must also go in and come out. Researchers in France and Germany report they have done this for the first time by reading out the quantum state of an atom directly by using electrodes.
Researchers at the Max Planck Institute in Germany have developed a complex network computer that is equally capable of performing arbitrary calculations as conventional computer, but does this under completely different conditions. Instead of a 0s and 1s in a binary system, this computer can in principle compute from, or be built from, any oscillating system, like a pendulum.
Conventional face capturing is well established and widely utilized in the entertainment industry to capture a 3D model of an actor's face. However, up to now, no method was capable of reconstructing facial hair or even handling it appropriately. A new method developed at Disney Research in Switzerland captures individual strands of facial hair and stores them separately from the actual human face until added. Or “shaved” away.
Take that, sports cars! Physicists at NIST can accelerate their beryllium ions from zero to 100 mph and stop them in just a few microseconds. What's more, the ions come to a complete stop and hardly feel the effects of the ride. And they're not just good for submicroscopic racing—NIST physicists think their zippy ions may be useful in future quantum computers.
Bioengineers at the University of California, San Diego have developed a method of modeling, simultaneously, an organism’s metabolism and its underlying gene expression. In addition to serving as a platform for investigating fundamental biological questions, this technology enables far more detailed calculations of the total cost of synthesizing many different chemicals, including biofuels.
