New and better ways of measuring high-tech energy consumption could lead to significant environmental and economic gains, a study from The Australian National University (ANU) has found. Researchers from ANU, the University of Texas at Austin, and the University of Washington have completed the first systematic profile of microprocessors, which could help lower the energy costs of electronic devices.
Scientists at The Scripps Research Institute in California and the Technion–Israel Institute of Technology have developed a "biological computer" made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips. Although DNA has been used for encryption in the past, this is the first experimental demonstration of a molecular cryptosystem of images based on DNA computing.
Researchers from North Carolina State University have developed a new technique that allows graphics processing units and central processing units on a single chip to collaborate—boosting processor performance by an average of more than 20%.
Some of the recent advancements in nanotechnology depend critically on how nanoparticles move and diffuse on a surface or in a fluid under non-ideal to extreme conditions. Georgia Institute of Technology has a team of researchers dedicated to advancing this frontier.
Data from Scripps Institution of Oceanography, NOAA, and the University of California, San Diego has been used by Google experts this week to sharpen the resolution of seafloor maps in the popular Google Earth application. The original version of the program, according to a Scripps geophysicist, had high resolution but was full of thousands of blunders from old data.
Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors.
Conventional scientific wisdom says that the interatomic forces between ions that control high-temperature processes are insensitive to the heating of the electron "glue" that binds the ions together. In effect, traditional atomistic simulations ignore electron temperature completely. However, physicists at the Lawrence Livermore National Laboratory have shown how electron temperature has a surprisingly large impact on phase stability and melting in refractory transition metals.
As the United States seeks to reinvigorate its job market and move past economic recession, the Massachusetts Institute of Technology examines manufacturing's role in America's economic future through work at the institute around manufacturing.
Taking inspiration from the yellow fattail scorpion, which uses a bionic shield to protect itself against scratches from desert sandstorms, scientists have developed a new way to protect the moving parts of machinery from wear and tear.
Two years after a devastating shark attack took his right leg, Craig Hutto became the test pilot for a unique and powerful new prosthetic leg being developed by mechanical engineer Michael Goldfarb and his team at Vanderbilt University. Now, six years later, Hutto’s leg has evolved into a sophisticated bionic leg version 2.0.
Givaudan has turned to researchers in the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory (CSAIL) for help analyzing taste-test results. To analyze taste-test results, the CSAIL researchers are using genetic programming, in which mathematical models compete with each other to fit the available data and then cross-pollinate to produce models that are more accurate.
A new University of Michigan computer model of disease transmission in space and time can predict cholera outbreaks in Bangladesh up to 11 months in advance, providing an early warning system that could help public health officials there.
Kodak is at a crossroads: It could go the way of Circuit City, or it could prosper after bankruptcy like General Motors. Even in bankruptcy, the company boasts some enviable strengths, including a rich collection of photo patents, and more than $4 billion in annual sales. But it may be too late for a transition.
Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. They have performed an experimental demonstration of quantum computation in which the input, the data processing, and the output remain unknown to the quantum computer.
A big reason for publishing scientific results is to inform others who can then use your data and conclusions to make additional discoveries, technologies or products. But what good are findings if they are, well, hard to find? Scientists from the SLAC National Accelerator Laboratory and Stanford University have a solution for those who design new chemical catalysts: They made an app.
For some time, researchers have explored flammable ice for low-carbon or alternative fuel or as a place to store carbon dioxide. Now, a computer analysis of the ice and gas compound, known as a gas hydrate, reveals key details of its structure. The results show that hydrates can hold hydrogen at an optimal capacity of 5 weight-percent, a value that meets the goal of a U.S. Department of Energy standard and makes gas hydrates practical and affordable.
After a long decade of deliberation, United Nations member countries will cast their vote this week on an issue that lasts literally just a second. Leap seconds are necessary to prevent atomic clocks from speeding ahead of solar time, but the United States and other countries want to abolish it for all time.
A new, 162-Teraflop peak supercomputer at the Pacific Northwest National Laboratory is helping scientists do more complex, advanced research in areas such energy storage and future power grid development. It also uses less energy than similar computers because of its water-fed cooling system.
Research into biofuel crops such as switchgrass and Miscanthus has focused mainly on how to grow these crops and convert them into fuels. But many steps lead from the farm to the biorefinery, and each could help or hinder the growth of this new industry. A new computer model developed at the University of Illinois can simplify this transition.
At the International Consumer Electronics Show, the gigantic gadget conclave in Las Vegas this week, several companies demonstrated how they can make mobile devices shake and rattle with great realism, employing a technology that uses plastics that function like muscles.
While physicists at the Large Hadron Collider smash together thousands of protons and other particles to see what matter is made of, they're never going to hurl electrons at each other. No matter how high the energy, the little negative particles won't break apart. But that doesn't mean they are indestructible. Using several massive supercomputers, a team of physicists has spilt simulated electron perfectly in half.
Purdue University physicists created computational tools that can predict the fleeting structures of iron-containing enzymes as they transform during chemical reactions. Many of these temporary but critical structures have eluded capture through traditional experimental methods such as X-ray crystallography.
In the basement of Hoyt Laboratory at Princeton University, Alexei Tyryshkin clicked a computer mouse and sent a burst of microwaves washing across a silicon crystal suspended in a frozen cylinder of stainless steel. The waves pulsed like distant music across the crystal and deep within its heart, billions of electrons started spinning to their beat. This choreographed dance is a stride toward developing quantum computers.
Addressing the complexity of Domain Name System Security (DNSSEC), Sandia National Laboratories computer scientist Casey Deccio has developed a new visualization tool known as DNSViz. DNSSEC is a standard security feature at high-level government offices, but it is extremely complex and Deccio’s tool helps simplify implementation.
University of California, Davis, researchers have proposed a radical new way of thinking about the chemical reactions between water and metal oxides. The new paradigm could lead to a better understanding of corrosion and how toxic minerals leach from rocks and soil. It could also help in development of green technology.
