No-wait Data Centers: System could reduce Transmission Delays by 99.6 Percent

July 18, 2014 3:59 pm | by Larry Hardesty, MIT | News | Comments

Big Web sites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a queue, and if the queues get too long, packets can be delayed.

Fundamental Chemistry Findings Could Help Extend Moore’s Law

July 16, 2014 11:49 am | by Lawrence Berkeley National Laboratory | News | Comments

Over the years, computer chips have gotten smaller, thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore’s Law. But there’s one component of the chip-making process in need of an overhaul if Moore’s law is to continue: the chemical mixture called photoresist.

Cray Awarded Contract to Install India's First Cray XC30 Supercomputer

July 16, 2014 3:33 am | by Cray | News | Comments

The Cray XC30 system will be used by a nation-wide consortium of scientists called the Indian Lattice Gauge Theory Initiative (ILGTI). The group will research the properties of a phase of matter called the quark-gluon plasma, which existed when the universe was approximately a microsecond old. ILGTI also carries out research on exotic and heavy-flavor hadrons, which will be produced in hadron collider experiments.

Scientists Track Quantum Errors in Real Time, Step Toward Age of Quantum Computing

July 15, 2014 4:33 pm | by Holly Lauridsen, Yale University | News | Comments

Scientists have demonstrated the ability to track real quantum errors as they occur, a major step in the development of reliable quantum computers. Quantum computers could significantly improve the computational power of modern computers, but a major problem stands in the way: information loss, or quantum errors. To combat errors, physicists must be able to detect that an error has occurred and then correct it in real time.

Inventor Pushes Solar Panels for Roads, Highways

July 15, 2014 12:06 pm | by Nicholas K. Geranios, Associated Press | News | Comments

The solar panels that Idaho inventor Scott Brusaw has built aren't meant for rooftops. They are meant for roads, driveways, parking lots, bike trails and, eventually, highways. Brusaw, an electrical engineer, says the hexagon-shaped panels can withstand the wear and tear that comes from inclement weather and vehicles, big and small, to generate electricity.

Chemists Discover Boron Buckyball

July 15, 2014 11:55 am | by Brown University | News | Comments

The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch. Researchers have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It’s the first experimental evidence that a boron cage structure — previously only a matter of speculation — does indeed exist.

Astronomers Bring Third Dimension to Doomed Star's Outburst

July 11, 2014 4:31 pm | by NASA | News | Comments

In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun's mass and made it the second-brightest star in the sky. Now, a team of astronomers has used extensive new observations to create the first high-resolution 3-D model of the expanding cloud produced by this outburst.

Making Quantum Connections: Speed of Information in a Spin Network

July 11, 2014 4:09 pm | by E. Edwards, Joint Quantum Institute | News | Comments

In quantum mechanics, interactions between particles can give rise to entanglement, which is a strange type of connection that could never be described by a non-quantum, classical theory. These connections, called quantum correlations, are present in entangled systems even if the objects are not physically linked. Entanglement is at the heart of what distinguishes purely quantum systems from classical ones — why they are potentially useful.

Speeding up Data Storage 1000x with Spin Current

July 11, 2014 3:52 pm | by Eindhoven University of Technology | News | Comments

The storage capacity of hard drives is increasing explosively, but the speed with which all that data can be written has reached its limits. Researchers presented a promising new technology which potentially allows data to be stored 1,000 times as fast in Nature Communications. The technology, in which ultra-short laser pulses generate a ‘spin current,’ also opens the way to future optical computer chips.
