Another step towards quantum computing – the Holy Grail of data processing and storage – was achieved when an international team of scientists that included researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) were able to successfully store and retrieve information using the nucleus of an atom.
In case anyone was wondering, I am far from alone in my call for a new science policy in the coming administration. It is the topic of the editorial in a recent issue of Science Magazine America's premier scientific journal.
Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants.
The world’s largest computing grid is ready to tackle mankind’s biggest data challenge from the earth’s most powerful accelerator. Today, three weeks after the first particle beams were injected into the Large Hadron Collider (LHC), the Worldwide LHC Computing Grid combines the power of more than 140 computer centers from 33 countries to analyze and manage more than 15 million gigabytes of LHC data every year.
If you've balanced a laptop computer on your lap lately, you probably noticed a burning sensation. That's because ever-increasing processing speeds are creating more and more heat, which has to go somewhere — in this case, into your lap.
People who hope to keep their age a secret won't want to go near a computer running this software.
A new Bluetooth system designed primarily for blind people places a layer of information technology over the real world to tell pedestrians about points of interest along their path as they pass them.
New "petascale" computer models depicting detailed climate dynamics, and building the foundation for the next generation of complex climate models, are in the offing.
A (fairly) new journal dedicated to Web-based research. Oh, and it's free.
Wireless Sensor Networks (WSNs) used to detect and report events including hurricanes, earthquakes, and forest fires and for military surveillance and antiterrorist activities are prone to subterfuge. In the International Journal of Security and Networks, computer scientists at Florida Atlantic University describe a new antihacking system to protect WSNs.
So-called 'intelligent' computer-based methods for classifying patient samples, for example, have been evaluated with the help of two methods that have completely dominated research for 25 years. Now Swedish researchers at Uppsala University are revealing that this methodology is worthless when it comes to practical problems.
The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego.
A time-and-money-saving question shared by commuters in their cars and networks sharing ever-changing Internet resources is: “What’s the best way to get from here to there?” A new algorithm developed by computer scientists at the University of California, San Diego helps answer that question, at least for computer networks, and it promises to significantly boost the efficiency of network routing.
An experiment has realized spin torque switching of a nanomagnet as fast as the fundamental speed limit allows.
