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.
New findings from a team of Lawrence Berkeley National Laboratory and Japanese scientists suggest that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well. A study at the Advanced Light Source revealed that contrary to suppositions, the formation of magnetic vortices in ferromagnetic nanodisks is an asymmetric phenomenon.
Electron microscopy reveals cellular structures in high detail, but only tiny portions of a cell can be seen at a time. A team of scientists has tackled this problem by developing new tools for stitching together thousands of electron microscopy images into single, high-resolution images of biological tissues—a "Google Earth" for cell biologists. A newly enhanced viewer is available for public use.
Quantum key distribution is not a new phenomenon and has been in commercial use for several years to secure communication networks. Recently, however, single particles of light, also known as photons, have been produced and implemented into a wireless QKD link, transmitting 40 cm through the air.
While bipeds and quadrupeds have reigned supreme in CG animation, attempts to create and control their skeleton-free cousins using similar techniques has proved time-consuming and laborious. Georgia Institute of Technology researchers have found a possible solution to this challenge by developing a way to simulate and control movement of computer-generated characters without a skeletal structure, anything from starfish and earthworms to an elephant’s trunk or the human tongue.
For decades it has been thought that a shock wave from a supernova explosion triggered the formation of our Solar System. Material from the exploding star generated cloud of dust and gas, which collapsed to form the Sun and its surrounding planets. New work from the Carnegie Institution provides the first fully 3D models for how this process could have happened.
When it comes to delivering data to users, the Web still works brilliantly. But for other functions such as allowing users to move between wireless networks or companies to shift traffic among servers, engineers are forced to implement increasingly cumbersome tweaks. A team of Princeton University researchers has released a plan to cut through that tangle and provide a simple solution to many of the problems involved with the Internet's growing pains.
It’s relatively easy to collect massive amounts of data on microbes. But the files are so large that it takes days to simply transmit them to other researchers and months to analyze once they are received. Researchers at Michigan State University have developed a new computational technique that relieves the logjam that these “big data” issues create.
Interactive proofs have emerged as one of the major research topics in theoretical computer science. In the classic interactive proof, a questioner with limited computational power tries to extract reliable information from a computationally powerful but unreliable respondent. The proofs get more complex with the addition of multiple respondents, and researchers recently solved a long-standing question about whether these types of proofs work in a quantum system.
Developed in partnership with AstraZeneca, a new private virtual laboratory product, Research Exchange, has been launched by Assay Depot. The cloud-based “laboratory” enables researchers to search for research services and vendors, communicate with experts, purchase services, and rate and review services through a single interface.
With billions of dollars and control of the U.S. smartphone and computer tablets markets at stake, jury selection began Monday in a closely watched trial between two of the world's leading tech companies over patents. Cupertino-based Apple is demanding $2.5 billion in damages from Samsung Electronics Co., an award that would dwarf the largest patent-related verdict to date.
A research team at the Georgia Tech Research Institute has developed a software tool that enables users to perform in-depth analysis of modeling and simulation data, then visualize the results on screen. The new data analysis and visualization tool offers improved ease of use compared to similar tools, the researchers say, and could be readily adapted for use with existing data sets in a variety of disciplines.
