Researchers at Nano-Meta Technologies Inc. have shown how to overcome key limitations of a material that could enable the magnetic storage industry to achieve data-recording densities far beyond today's computers. The new technology could make it possible to record data on an unprecedented small scale using tiny "nanoantennas" and to increase the amount of data that can be stored on a standard magnetic disk by 10 to 100 times.
Rice Univ. is preparing to offer its researchers who deal in “big data” the opportunity to compute in the cloud with fewer barriers. Rice is installing the Big Research Data Cloud (BiRD Cloud), which will allow for cloud bursting. That means data-intensive tasks can spill over into outside cloud-computing systems when necessary, essentially providing unlimited computing capacity.
Carpe diem…seize the day. This Latin phrase, coined by the Roman poet Horace in 23 BC, is used often to encourage us to take full advantage of the opportunities each day provides. In modern times with seemingly limitless amounts of data on any conceivable subject available at our fingertips, organizations globally are developing strategies to leverage this growing data volume to enhance business success.
A team of New York Univ. and Univ. of Barcelona physicists has developed a method to control the movements occurring within magnetic materials, which are used to store and carry information. The breakthrough could simultaneously bolster information processing while reducing the energy necessary to do so.
The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but the fundamentals of computation, mixing two inputs into a single output, currently require too much space and power when done with light.
Researchers from the Queen Mary Univ. of London gave a computer program the outline of how a magic jigsaw puzzle and a mind-reading card trick work, as well the results of experiments into how humans understand magic tricks, and the system created completely new variants on those tricks which can be delivered by a magician.
Lawrence Livermore National Laboratory (LLNL) announced a contract with IBM to deliver a next-generation supercomputer in 2017. The system, to be called Sierra, will serve the National Nuclear Security Administration’s Advanced Simulation and Computing program. Procurement of Sierra is part of a DOE-sponsored Collaboration of Oak Ridge, Argonne and Lawrence Livermore national labs to accelerate the development of high-performance computing.
Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, Lawrence Berkeley National Laboratory climate scientist Michael Wehner was able to complete a run in just three months. Not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms.
While the Martinis Lab at the Univ. of California, Santa Barbara has been focusing on quantum computation, they have also been exploring qubits for quantum simulation on a smaller scale. The team worked on a new qubit architecture, which is an essential ingredient for quantum simulation, and allowed them to master the seven parameters necessary for complete control of a two-qubit system.
The tree has been an effective model of evolution for 150 years, but a Rice Univ. computer scientist believes it’s far too simple to illustrate the breadth of current knowledge. Rice researcher Luay Nakhleh and his group have developed PhyloNet, an open source software package that accounts for horizontal as well as vertical inheritance of genetic material among genomes.
Today, petabytes of digital information are generated daily by such sources as social media, Internet activity, surveillance sensors and advanced research instruments. The results are often referred to as “big data”—accumulations so huge that highly sophisticated computer techniques are required to identify useful information hidden within. Graph analysis is a prime tool for finding the needle in the data haystack.
Here is an idea worth following: “share” for tenure; “like” to get cited. Academic researchers are turning to social media more and more, according to new research.
New research demonstrates how glass can be manipulated to create a material that will enable computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.
Laser surgery to correct eyesight is common practice, but did you know that technology developed for use in space is now commonly used to track the patient's eye and precisely direct the laser scalpel? If you look at a fixed point while tilting or shaking your head, your eyes automatically hold steady, allowing you to see clearly even while moving around. This neat trick of nature is a reflex and we are usually unaware that it even happens.
Researchers studying iron-based superconductors are combining novel electronic structure algorithms with the high-performance computing power of the U.S. Dept. of Energy’s Titan supercomputer at Oak Ridge National Laboratory to predict spin dynamics, or the ways electrons orient and correlate their spins in a material.
Microsoft is releasing a $199 fitness band that also checks your email and even pays for coffee as the software company seeks to challenge Apple and others in the still-infant market for wearable devices. The Microsoft Band will work with the company's new Microsoft Health system for consolidating health and fitness data from various gadgets and mobile apps.
Most modern cryptographic schemes rely on computational complexity for their security. In principle, they can be cracked, but that would take a prohibitively long time, even with enormous computational resources. There is, however, another notion of security—information-theoretic security—which means that even an adversary with unbounded computational power could extract no useful information from an encrypted message.
Scientists at IBM and leading global energy company Repsol S.A. announced this week the world’s first research collaboration to leverage cognitive technologies that will help transform the oil and gas industry. IBM and Repsol are jointly developing two prototype cognitive applications specifically designed to augment Repsol’s strategic decision making in the optimization of oil reservoir production and in the acquisition of new oil fields.
As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation.
Inside Massachusetts Institute of Technology’s Building 41, a small, Roomba-like robot is trying to decided where to go. As the robot considers its options, its “thoughts” are projected on the ground in the form of different colored dots and lines. This new visualization system, called “measurable virtual reality”, combines projectors with motion-capture technology and animation software to project a robot’s intentions in real time.
If the surroundings are designed to be sufficiently stimulating, even a simple computer screen is enough to generate an intense cinematic experience. After observing some 300 study subjects, researchers in Germany have concluded that the angle of viewing does not play a vital role in the cinematic experience. Instead, the presence of so-called contextual visual cues plays a greater role in actually drawing viewers into a movie.
Quantum technology devices, such as high-precision sensors and specialised superfast computers, often depend on harnessing the delicate interaction of atoms. However, the methods for trapping these tiny particles are hugely problematic because of the atoms’ tendency to interact with their immediate environment. Scientists in the U.K. have recently shown how to make a new type of flexibly designed microscopic trap for atoms.
For many high school seniors, fall means deciding where to apply for college and maybe visiting a guidance counselor. Data crunchers hope to help. The popularity of social media sites and advancements in the ability to analyze the vast amounts of data we put online give members of the class of 2015 more tools than ever to help chart their next step, even if finding the right college is an inexact science.
A Silicon Valley startup has developed technology to let dispatchers know when a police officer's weapon has been fired. The product by Yardarm Technologies would notify dispatchers in real time when an officer's gun is taken out of its holster and when it's fired. It can also track where the gun is located and in what direction it was fired.
At first glance, the static, greyscale display created by a group of researchers in Hong Kong might not catch the eye of a thoughtful consumer in a market saturated with flashy, colorful electronics. But a closer look at the specs could change that: the ultra-thin LCD screen is capable of holding 3-D images without a power source, making it a compact, energy-efficient way to display visual information.
